Ethyl Norbornyl Alkyl Ethers, Organoleptic Uses Thereof and Process for Preparing Same

The present invention relates to ethyl norbornyl alkyl ethers of our invention defined according to the structure: ##STR5## wherein R represents C.sub.1 -C.sub.4 lower alkyl and uses thereof in order to alter, modify or enhance the aroma of consumable materials.

There has been considerable work performed relating to substances which can be used to impart (modify, augment or enhance) fragrances to (or in) various consumable materials. These substances are used to diminish the use of natural materials, some of which may be in short supply and to provide more uniform properties in the finished product.

Long-lasting, fresh, green, stemmy, ozoney, woody, citrusy, camphoraceous, rooty, cinnamon and fruity aromas are desirable in several types of perfume compositions, perfumed articles and colognes.

The perfume use of norbornene alcohol and ester derivatives having the structures: ##STR6## wherein R.sub.1 is C.sub.1 -C.sub.4 alkyl is disclosed in U.S. Pat. No. 3,860,635 particularly at Example XV at column 16 thereof. Such compounds and the synthesis thereof are also disclosed by Bobyleva, Zh. Org. Kh. Volume 13, No. 10, pages 2085-92, October 1977. In addition, ethers of norbornene derivatives having the structures: ##STR7## are disclosed as well as the process for preparing same according to the reaction: ##STR8## in Shield, Can. J. Chem. Volume 49, 1971, page 1142.

U.S. Pat. No. 3,927,116 indicates the utility of certain vinyl norbornyl ethers having the structure: ##STR9## wherein R.sub.2 represents C.sub.1 -C.sub.4 alkyl as being intermediate for the preparation of detergents at column 9 lines 10-15. No indication in U.S. Pat. No. 3,927,116 of the use of such compounds in perfumery, for augmenting or enhancing the aroma of perfumes, perfumed articles and colognes, is suggested either implicitly or explicitly in U.S. Pat. No. 3,927,116.

Furthermore, considerable difficulties have heretofore been encountered in using compounded hypochlorite bleach or sterilizing solutions with perfumed oils so that a stable long-lasting, single phase commercially feasible bleach or sterilizing solution has been difficult to obtain, particularly wherein the desired aroma of the article bleached or sterilized (e.g., clothing) has a pleasant and stable and consistent aroma on drying (and not the usual "hypochlorite-bleached-article" aroma). The problem has been defined in United Kingdom Patent Specification No. 886,084 published on Jan. 3, 1962 wherein it is stated that a stable "dispersion" of hypochlorite-resistent perfume in aqueous solutions of hypochlorites was formulated. United Kingdom Patent Specification No. 886,084 discloses the preparation of an aqueous "solution" of a hypochlorite containing a hypochlorite resistant perfume and a surface active quaternary ammonium compound of the betaine type soluble in the hypochlorite solution. Such ammonium compounds have the generic structure: ##STR10## wherein each of R.sub.1 ", R.sub.2 ", R.sub.3 " and R.sub.4 " are alkyl. One of the features of the perfumed solutions produced in accordance with said United Kingdom Patent Specification No. 886,084 is indicated to be that the solution exhibits foaming properties. Another feature of United Kingdom Patent Specification No. 886,084 is stated to be that the perfumed solutions covered by the patent are found to be clear and homogeneous after eight weeks of storage at room temperature. Nevertheless, betaines such as "Ambiteric D" as are discussed therein are not so broadly useful when used in concentrations of from 0.15% up to 4.0% (based on total weight of bleach or sterilizing solution) as to have the ability to be used in conjunction with perfume oils which should be incorporated into thickened, high viscous hypochlorite bleaches or sterilizers having excellent surface tension properties so that long lasting stable soluble single phase thickened perfumed aqueous alkali metal hypochlorite bleach or sterilizing solutions having long lasting pleasant stable aromas are obtained, particularly where the quantity of perfume oil in the bleach or sterilizing substance is at levels of between 0.02% and 0.8% by weight of the total bleach or sterilizing solution. The need for such aromas (e.g., "citrusy") to be present in such bleach or sterilizing solutions exists so that the disagreeable characteristic "hypochlorite" aroma is substantially eliminated from aromas of the product to which the bleach or sterilizing solution is applied; particularly on dry-out, as well as from the aroma of the hands of the user when they are in direct contact with such bleach or sterilizing solutions.

U.S. Pat. No. 3,560,389 also discloses the feasibility of using perfume oils in hypochlorite bleaches or sterilizers at column 3, lines 37-40 but the disclosure is limited to inclusion of various detergents in addition to amine oxides, such as lithium lauryl sulfate and sodium lauryl ether sulfate and/or is further limited to include hydrotropes such as sodium xylene sulfonate in addition to the amine oxide. Exclusion of such hydrotropes and detergents additional to the amine oxides and diphenyl oxide derivatives of our invention is desirable not only to cause the ethyl norbornyl alkyl ethers of our invention to function properly, but also from an ecological standpoint.

European Chemical News, Volume 13, Jan. 18, 1968, sets forth a synopsis of South African Patent No. 67/4667 which corresponds to U.S. Pat. No. 3,560,389, but the reference also states at page 42:

"Alternatively, a detergent with bleaching or bacteriocidal properties can be formulated. Perfuming bleaching solutions is now possible."

Neither the South African nor the United States Patents, however, indicate the advantages and usefulness of limiting the detergents either to (a) compounds having the generic structure: ##STR11## wherein at least one of R.sub.1 and R.sub.2 represents C.sub.10 -C.sub.12 straight chain or branched chain alkyl and when one of R.sub.1 or R.sub.2 is C.sub.10 -C.sub.12 branched or straight chain alkyl, the other or R.sub.1 or R.sub.12 is pH-adjusted hydrogen and wherein M.sub..alpha. and M.sub..beta. are the same or different and each represents alkali metal which may be sodium, lithium or potassium, or (b) to mixtures of compounds having the structure: ##STR12## with at least one amine oxide defined according to the structure: ##STR13## of excluding from the formulation a hydrotrope or of specifying the nature of the perfume oil useful in the perfumed bleach or sterilizing solution (wherein A and B are each separately methyl or taken together, complete a morpholino ring and wherein R.sub.3 '" is straight chain alkyl having from 11 up to 13 carbon atoms).

U.S. Pat. No. 3,876,551 in attempting to solve the foregoing problem discloses a stable single phase aqueous alkali metal hypochlorite liquid perfume bleach or sterilizing compositio comprising an aqueous mixture of (1) an amine oxide composition consisting essentially of at least one morpholino- and/or dimethyl (C.sub.11 -C.sub.13 straight chain alkyl) amine oxide in an amount greater than 55% of said amine oxide composition, (2) at least one alkali metal hydroxide, (3) at least one alkali metal hypochorite, and (4) a perfume oil compatible with the mixture capable of imparting a "woody" or a "floral" or a "clean fresh" or a "citrusy" note to the bleach or sterilizing composition; the mixture having a pH in the range of from 12 to 13.5 and the mixture excluding hydrotropes as well as all surfactants except the amine oxide. U.S. Pat. No. 3,876,551 also attempts to solve the foregoing problem by disclosing a process for producing the above-named mixture comprising the steps of combining an amide oxide composition consisting essentially of one or more morpholino and/or dimethyl C.sub.11 -C.sub.13 straight chain alkyl amine oxide(s) with the perfumed oil to form an amine oxide-perfume oil premix; admixing the amine oxide-perfume oil premix with an aqueous alkali metal hypochlorite solution, and combining an alkali metal hydroxide with the solution whereby the final pH of the mixture is from 12 up to 13.5. In a further effort to solve the foregoing problem U.S. Pat. No. 3,876,551 also discloses adjustment of the pH of the aqueous metal hypochlorite solution initially to the range of 12-13.5 and then combining the resulting aqueous hypochlorite solution with the aforementioned premix. The resulting composition is indicated to cause products to which said composition is applied to have eliminated therefrom the disagreeable characteristics "hypochlorite" aroma and instead to have a "clean fresh" or "floral" or "woody" or "citrusy" aroma to be imparted to the treated products. In addition, it is stated that the hands of the individual user after using and being in direct contact with the hypochlorite composition will not have the disagreeable characteristics "hypochlorite" aroma but instead will have a pleasant "clean fresh" or "floral" or "woody" or "citrusy" aroma.

The disadvantage of the system of U.S. Pat. No. 3,876,551 however, concerns (a) the inability to use a thickener in the system whereby the resulting liquid has a viscosity of 5-25 centipoises at 20.degree.-40.degree. C. and (b) the relatively low degree of chemical stability and substantive stability of the perfume oil and of the single liquid phase system. Nothing in U.S. Pat. No. 3,876,551 indicates such a high degree of stabilities of the perfume-hypochlorite system as exists in the system of the present invention; wherein there is also included a thickener. Indeed, the stabilities using the system of the instant invention are far greater even at levels as low as 3% hypochlorite and are also relatively stable (from a standpoint of chemical stability of perfume oil, substantive stability of perfume oil and phase separation stability taken in combination with one another) at levels of as high as 10% hypochlorite in aqueous solution. Thus, the instant system gives rise to unexpected, unobvious and advantageous properties over the systems taught in the prior art.

Furthermore, nothing in the prior art including the teaching of U.S. Pat. No. 3,876,551 states either explicitly or implicitly the compatability of a thickener in the instant system, such as sodium palmitate, sodium stearate, potassium palmitate, potassium stearate, lithium palmitate, lithium stearate, lithium laurate, potassium laurate or sodium laurate whereby a stable gel (as opposed to a liquid) phase perfumed hypochlorite system or perfumed oil stabilizer emulsifier system "premix" may be produced.

The combination of the compound group having the structure: ##STR14## (wherein R.sub.1, R.sub.2, M.sub..alpha. and M.sub..beta. are defined, supra) with perfume and hypochlorite bleach in general, is set forth in the Kao Soap Company, Japanese Patent No. 25514/79 filed on Nov. 2, 1973 and opened for public inspection on June 19, 1975. Thus, on page 2, at column 4, line 15, the compound: ##STR15## is disclosed for use in conjunction with the perfumed hypochlorite bleaches. The claim of the Kao Soap Patent is as follows:

Claim: An aromatic liquid bleaching composition containing, as active ingredient, sodium hypochlorite, which comprises one or more of simple perfumes or compounded perfumes selected from the group consisting of anisole, benzophenone, benzylphenyl ether, bromelia, cedrenyl acetate, p-tertiary butylcyclohexanol, dimethylbenzylcarbinyl acetate, dihydroterpinyl acetate, diphenyl oxide, dimethylbenzylcarbinol, dimethylphenylcarbinol, dihydroterpineol, fenchyl acetate, fenchyl alcohol, p-methyldimethylbenzylcarbinol, methylphenylcarbinyl acetate, methyl-n-valerate, muskmoskene, muscarone, methylamyl ketone, phenylethyldimethylcarbinyl acetate, rose phenone, styrallyl propionate, tetra hydromuguol, tetra hydromuguyl acetate, tetrahydrolinalool, tetrahydrolinalyl acetate, verool, velveton, verdox, coniferan and yarayara, and a surface active agent which can stably be dissolved in an aqueous solution of sodium hypochlorite.

Furthermore, the use of such compounds as those having the structure: ##STR16## (wherein R.sub.1, R.sub.2, M and M have been previously defined) with hypochlorite bleaches is documented in the brochure of Dow Chemical entitled "DOWFAX Surfactants" and is covered in the Dow Chemical Company U.S. Pat. No. 3,172,861 issued on Mar. 9, 1965.

Nothing in the prior art discloses, however, the utility of the thickeners of the instant application taken together with a perfume oil (e.g., "diisoamylene" or "diisoamylene epoxide") and one of the compounds defined according to the generic structure: ##STR17## (wherein R.sub.1, R.sub.2, M.sub..alpha. and M.sub..beta. have been defined, supra) in hypochlorite bleaches, particularly where the hypochlorite concentration is greater than 7%. More particularly, nothing in the prior art discloses the use of such systems in conjunction with a thickener such as sodium palmitate, potassium palmitate, sodium stearate, potassium stearate, sodium laurate, potassium laurate, lithium laurate, lithium stearate or lithium palmitate, whereby a stable gelled perfumed hypochlorite mixture is formed or whereby a "premix" gel-phase perfume oil-stabilizing/emulsifying agent is formed.

The ethyl norbornyl alkyl ethers of our invention are unique insofar as the aforementioned systems are concerned for use in hypochlorite bleaches. Nothing in the prior art discloses any organic compounds even remotely similar to the ethyl norbornyl alkyl ethers of our invention for use as a stable aroma augmenting or enhancing agent in hypochlorite bleaches.

FIG. 11 represents a cut-away side elevation view of apparatus used in forming perfumed polymers which contain imbedded therein at least one of the ethyl norbornyl alkyl ethers of our invention.

FIG. 12 is a front view of the apparatus of FIG. 11 looking in the direction of the arrows.

Referring to FIGS. 11 and 12, there is provided a process for forming scented polymer elements (wherein the polymer may be a thermoplastic polymer such as low density polyethylene or polypropylene or copolymers of ethylene and vinyl acetate or mixtures of polymers and copolymers such as copolymers of ethylene and vinyl acetate and polyethylene) such as pellets useful in the formation of plastic particles useful in fabricating certain articles which may be perfumed (and, further, which may be exposed to chlorine bleaches). This process comprises heating the polymer or mixture of polymers to the melting point of said polymer or mixture of polymers, e.g., 250.degree. C. in the case of low density polyethylene. The lower most portion of the container is maintained at a slightly lower temperature and the material in the container is taken off at such location for delivery through the conduit. Thus, referring to FIGS. 11 and 12, in particular, the apparatus used in producing such elements comprises a device for forming the polymer containing the perfume, e.g., polyethylene or polyethylene-polyvinyl acetate or mixtures of same or polypropylene, which comprises a vat or container 212 into which the polymer taken alone or in admixture with other copolymers and the perfuming substance which is at least one of the ethyl norbornyl alkyl ethers of our invention or mixtures of ethyl norbornyl alkyl ethers of our invention and other compatible perfumes is placed. The container is closed by means of an air-tight lid 228 and clamped to the container by bolts 265. A stirrer 273 traverses the lid or cover 228 in an air-tight manner and is rotatable in a suitable manner. A surrounding cylinder 212A having heating coils which are supplied with electric current through cable 214 from a rheostate or control 216 is operated to maintain the temperature inside the container 212 such that the polymer in the container will be maintained in the molten or liquid state. It has been found advantageous to employ polymers at such a temperature that the viscosity will be in the range of 90-100 sayboldt seconds. The heater 218 is operated to maintain the upper portion of the container 212 within a temperature range of, for example, 220.degree.-270.degree. C. in the case of low density polyethylene.

The bottom portion of the container 212 is heated by means of heating coils 212A regulated through the control 220 connected thereto through a connecting wire 222 to maintain the lower portion of the container 212 within a temperature range of 220.degree.-270.degree. C.

Thus, the polymer or mixture of polymers added to the container 212 is heated from 10-12 hours, whereafter the perfume composition or perfume material which contains one or more of the ethyl norbornyl alkyl ethers of our invention is quickly added to the melt. Generally, about 10-45 percent by weight of the resulting mixture of the perfumery substance is added to the polymer.

After the perfume material is added to the container 212, the mixture is stirred for a few minutes, for example, 5-15 minutes and maintained within the temperature ranges indicated previously by the heating coil 212A. The controls 216 and 220 are connected through cables 224 and 226 to a suitable supply of electric current for supplying the power for heating purposes.

Thereafter, the valve "V" is opened permitting the mass to flow outwardly through conduit 232 having a multiplicity of orifices 234 adjacent to the lower side thereof. The outer end of the conduit 232 is closed so that the liquid polymer in intimate admixture with one or more of the ethyl norbornyl alkyl ethers of our invention or mixture of ethyl norbornyl alkyl ethers and one or more other substances, will continuously drop through the orifices 234 downwardly from the conduit 232. During this time, the temperature of the polymer intimately admixed with the perfumery substance in the container 212 is accurately controlled so that a temperature in the range of from about 240.degree.-250.degree. C., for example, (in the case of low density polyethylene) will exist in the conduit 232. The regulation of the temperature through the controls 216 and 220 is essential in order to insure temperature balance to provide for the continuous dripping or dropping of molten polymer intimately admixed with the perfume substance which is all of or which contains one or more of the ethyl norbornyl alkyl ethers of our invention, through the orifices 234 at a rate which will insure the formation of droplets 236 which will fall downwardly onto a moving conveyor belt 238 caused to run between conveyor wheels 240 and 242 beneath the conduit 232.

When the droplets 236 fall onto the conveyor 238, they form pellets 244 which harden almost instantaneously and fall off the end of the conveyor 238 into a container 250 which is advantageously filled with water or some other suitable cooling liquid to insure the rapid cooling of each of the pellets 244. The pellets 244 are then collected from the container 250 and utilized for the formation of functional products, e.g., garbage bags and the like.

The present invention provides ethyl norbornyl alkyl ethers of our invention defined according to the generic structure: ##STR28## including the compounds having the structures: ##STR29## and, optionally, including compounds defined according to the structure: ##STR30## wherein R represents C.sub.1 -C.sub.4 alkyl, e.g., methyl, ethyl, n-propyl, isopropyl, n-butyl, secondary butyl, 2-methylpropyl, and t-butyl.

The ethyl norbornyl alkyl ethers of our invention produced according to the process of our invention are capable of augmenting or enhancing fresh, green, stemmy, ozoney, woody, citrusy, camphoraceous, rooty, cinnamon and fruity aromas in perfume compositions, colognes and perfumed articles including soaps, bleaches, nonionic, cationic, anionic and zwitterionic detergents, fabric softener articles and perfumed articles.

The ethyl norbornyl alkyl ethers of our invention are produced using as starting materials either compounds defined according to the structure: ##STR31## (including the compounds having the structure: ##STR32## in admixture with the compounds having the structure: ##STR33## or, in the alternative, the mixture of compounds defined according to the generic structure: ##STR34## which includes the mixture of compounds having the structures: ##STR35## taken further together with the compound having the structure: ##STR36##

The mixture of compounds defined according to the structure: ##STR37## is shown to be prepared in U.S. Pat. No. 4,351,347 issued on Sept. 28, 1982 the disclosure of which is incorporated by reference herein and is further indicated to be prepared in U.S. Pat. No. 3,927,116 the disclosure of which is incorporated by reference herein.

The mixture of compounds defined according to the structures: ##STR38## is shown to be prepared in U.S. Pat. Nos. 4,379,060 issued on Apr. 5, 1983; 4,330,416 and 4,311,861 the disclosures of which are incorporated herein by reference.

In each of the cases the compounds having the structure: ##STR39## or the mixture of compounds having the structures: ##STR40## is hydrogenated using standard hydrogenation catalysts according to either the reaction: ##STR41##

In carrying out these reactions, the reaction catalyst may be Raney nickel, palladium, platinum, palladium supported on carbon, nickel supported on alumina (e.g., Ni480-P manufactured by the Calsicat Corporation).

At the end of the reaction, the reaction product is cooled and the catalyst is filtered. The reaction mass is then "worked up" as by washing and the organic phase is distilled by means of, for example, fractional distillation.

Specific examples of the ethyl norbornyl alkyl ethers produced according to the foregoing processes and useful for the practice of our invention are set forth in Table I below.

The ethyl norbornyl alkyl ethers of our invention and one or more auxiliary perfume ingredients, including, for example, hydrocarbons, alcohols, ketones, aldehydes, nitriles, esters, lactones, ethers other than said ethyl norbornyl alkyl ethers of our invention, hydrocarbons, synthetic essential oils and natural essential oils may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly and preferably in citrusy and/or green, woody and/or piney fragrances.

Such perfume compositions usually contain (a) the main note or the "bouquet" or foundation stone of the composition; (b) modifiers which round off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation; and (d) topnotes which are usually low boiling fresh smelling materials.

In perfume compositions, it is the individual components which contribute to their particular olfactory characteristics, however the overall sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, one or more of the ethyl norbornyl alkyl ethers of our invention can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.

The amount of ethyl norbornyl alkyl ethers of our invention which will be effective in perfume compositions as well as in perfumed articles and colognes depends upon many factors, including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.005% of ethyl norbornyl alkyl ethers of our invention or even less (e.g., 0.002%) can be used to impart fresh, green, stemmy, ozoney, woody, citrusy, camphoraceous, rooty, cinnamon and fruity aroma nuances to soaps, cosmetics, detergents (including anionic, nonionic, zwitterionic and cationic solid or liquid detergents) or other products. The amount employed can range up to 70% of the fragrance components and will depend upon considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.

The ethyl norbornyl alkyl ethers of our invention are useful (taken alone or togehter with other detergents in perfume compositions) in detergents and soaps, space odorants and deodorants, perfumes, colognes, toilet water, bath preparations such as lacquers brilliantines, pomades and shampoos; cosmetic preparations, such as creams, deodorants, hand lotions and sun screens; powders such as talcs, dusting powders, face powders and the like. As little as 0.27% of the ethyl norbornyl alkyl esters of our invention will suffice to impart an intense fresh, green, stemmy, ozoney, woody, citrusy, comphoraceous, rooty, cinnamon and fruity notes to citrusy, woody and floral perfume formulations. Generally, no more than 5% of the ethyl norbornyl alkyl ethers of our invention based on the ultimate end product is required to be used as is or in the perfume composition.

Furthermore, as little as 0.25% of the ethyl norbornyl alkyl ethers of our invention will suffice to impart such aroma to perfumed articles per se, whether in the presence of other perfume materials or whether used by itself. Thus, the range of use of the ethyl norbornyl alkyl ethers of our invention in perfumed articles may vary from 0.25% up to 5% by weight based on the total weight of the perfumed article.

In addition, the perfume composition or fragrance composition of our invention can contain a vehicle, or carrier for the ethyl norbornyl alkyl ethers of our invention. The vehicle can be a liquid such as a non-toxic alcohol, e.g., ethanol, a non-toxic glycol, e.g., propylene glycol or the like. The carrier can also be an absorbent solid, such as a gum (e.g., gum arabic), or components for encapsulating the composition by means of coacervation (such as gelatin).

It will thus be apparent that the ethyl norbornyl alkyl ethers of our invention can be utilized to alter, modify or enhance aroma of perfume compositions, colognes or perfumed articles.

Furthermore, several processes may be used in order to produce a thickened, highly viscous hypochlorite bleaching or sterilizing solution whereby the desired aroma profiles are imparted to the articles treated with said hypochlorite solutions.

Thus, for example, the ethyl norbornyl alkyl ethers may be premixed with the diphenyl oxide derivative or diphenyl oxide derivative-amine oxide solubilizer-stabilizer (having the structures, respectively: ##STR52## and the resulting ethyl norbornyl alkyl ethers-diphenyl oxide derivative or ethyl norbornyl alkyl ethers-diphenyl oxide derivative-amine oxide premix is then mixed with the hypochlorite bleaching or sterilizing solution with stirring. Immediately after such addition, an aqueous alkali metal hydroxide solution is added to the mixture to bring the pH to the range of 11-14.0. A pH of less than 11 is not desired since it is difficult to achieve a single phase stable system at low pH's. A pH higher than 14.0 will also create a system which (1) is unnecessarily corrosive; (2) will narrow the range of perfume oils useable (in conjunction with the ethyl norbornyl alkyl ethers) of the system and (3) will limit the particular ingredients useable in such perfume oils in conjunction with the ethyl norbornyl alkyl ethers. On the other hand, if for example, the ethyl norbornyl alkyl ethers is used alone or further in combination with (i) diisoamylene epoxides; (ii) diisoamylenes as described in application for U.S. Letters Patent, Ser. No. 188,576 filed on Oct. 9, 1980; or (iii) acyl diisoamylene derivatives described in application for U.S. Letters Patent, Ser. No. 184,132 filed on Sept. 4, 1980 and/or (iv) ketal derivatives of acyl diisoamylene derivatives described in application for U.S. Letters Patent, Ser. No. 212,993 filed on Dec. 4, 1980, a pH of about 14.0 and even slightly higher (e.g., 14.1) is acceptable.

The aqueous alkali metal hydroxide can be added to the aqueous alkali metal hypochlorite solution before adding the diphenyl oxide derivatives (taken alone or in conjunction with the amine oxide) or the ethyl norbornyl alkyl ethers or mixtures of ethyl norbornyl alkyl ethers with other materials such as diisoamylene epoxides. Indeed, the ingredients: the ethyl norbornyl alkyl ethers; the alkali metal hydroxide and the diphenyl oxide derivative or diphenyl oxide derivative-amine oxide composition (having the structures, respectively ##STR53## may be added or admixed in any order which is convenient to the formulator. One desirable process involves first forming the diphenyl oxide derivative or diphenyl oxide derivative-amine oxide composition-ethyl norbornyl alkyl ethers "premix", mixing the premix with the alkali metal hypochlorite solution and finally adjusting the pH of the solution with alkali metal hydroxide to bring the pH to within the range of 11-14.0. A second, more preferable process, involves first adjusting the pH of the aqueous alkali metal hypochlorite solution to 11-14.0 and then admixing the solution with the afore-described "premix".

The alkali metal hypochlorites preferred in the practice of our invention are: sodium hypochlorite, potassium hypochlorite and lithium hypochlorite or mixtures of same. The alkali metal hypochlorites preferred in the practice of this invention are: lithium hydroxide, potassium hydroxide and sodium hydroxide, or, if desired, mixtures of such hydroxides.

The temperature at which the composition of our invention remains both substantially stable and commercially useful for the purposes set forth herein (that is, remains as a clear single aqueous or gel phase) and retains (1) the desired properties inherent in the known bleaching and sterilizing uses of aqueous alkali metal hypochlorite liquid or gel solutions, and (2) the properties imparted thereto as a result of the use of the ethyl norbornyl alkyl ethers which impart to articles previously subjected to the aqueous alkali metal hypochlorite gel or liquid solutions a desired aroma profile, varies from approximately 20.degree. F. up to approximately 120.degree. F. At temperatures below 20.degree. F. a two-phase system usually occurs and at temperatures higher than 120.degree. F. the bleaching or sterilizing efficiency of the compositions of our invention is diminished at an excessive rate.

When it is desired to (1) initially form the C.sub.10 -C.sub.12 straight chain or branched chain diphenyl oxide alkali metal sulfonate or diphenyl oxide derivative-amine oxide-ethyl norbornyl alkyl ether premix; (2) then combine the resulting premix with an alkali metal hypochlorite solution; (3) then add the thickening agent and then (4) adjust the pH of the resulting solution to the range of 11-14.0, then the temperature of mixing ranges are considered to be within the scope of this invention as follows:

In any event, wherever a mixing unit operation involves the aqueous alkali metal hypochlorite solution, the temperature of mixing is limited to the range of 20.degree. F.-120.degree. F. Where the mixing unit operation involves the mixing of ethyl norbornyl alkyl ethers, the upper bound of the temperature range is limited by the stability of the ethyl norbornyl alkyl ethers or other perfume ingredient mixed with the ethyl norbornyl alkyl ethers useable in the practice of our invention; and the lower bound of said temperature range is limited by the least temperature where a single liquid phase or gel phase including the ethyl norbornyl alkyl ethers or other ingredient admixed therewith will exist. Where a unit mixing operation of the process of our invention involves the mixing of one or more diphenyl oxide derivatives having the generic structure: ##STR54## taken alone or taken together with one or more amine oxides having the generic structure: ##STR55## with other materials, the upper bound of the temperature range is the decomposition point of any one of the diphenyl oxide derivatives or amine oxide components and the lower bound is the least temperature where a single liquid phase or gel phase, including the diphenyl oxide derivatives or diphenyl oxide-amine oxide mixture will exist.

Preferred diphenyl oxide derivative compositions from a practical standpoint useful in the practice of our invention are compounds having the structure: ##STR56## where th C.sub.12 H.sub.25 moiety represents one or a series of different branched chains; compounds defined according to the structure: ##STR57## where the C.sub.12 H.sub.25 moiety represents one or a series of different branched chains; compounds defined according to the structure: ##STR58## and compounds defined according to the structure: ##STR59## otherwise known as DOWFAX.RTM. 2A1 in the case where one or R.sub.1 or R.sub.2 represents branched C.sub.12 H.sub.25 alkyl chains and the other of R.sub.1 or R.sub.2 represents hydrogen, or DOWFAX.RTM. 3B2 in the case where one one of R.sub.1 or R.sub.2 represents straight C.sub.10 alkyl chain and the other of R.sub.1 or R.sub.2 represents hydrogen (DOWFAX.RTM. being a registered trademark of the Dow Chemical Company of Midland, Mich.).

When used in conjunction with the diphenyl oxide derivatives preferred amine oxide compositions, from a practical standpoint, useful in the practice of our invention are the commercially available (1) dimethyl "cocoamine" oxide (a mixture which is dominated by dimethyl-C.sub.12 -C.sub.16 straight chain alkyl amine oxides; more particularly a mixture containing approximately 70% C.sub.12 straight chain alkyl amines oxides, approximately 25% of straight chain C.sub.14 alkyl amine oxides and approximately 4% straight chain C.sub.16 alkyl amine oxides) and (2) N-cocomorpholine oxide, a mixture dominated by straight chain C.sub.12 -C.sub.16 alkyl morpholine oxides (specifically containing approximately 70% straight chain C.sub.12 alkyl morpholine oxide, approximately 25% straight chain C.sub.14 alkyl morpholine oxide, and approximately 4% straight chain C.sub.16 alkyl morpholine oxide). Commercial examples of such amine oxide compositions are: AROMOX.RTM. DMC-W and AROMOX.RTM. DMMC-W which are 30% aqueous dimethyl cocoamine oxide solutions and AROMOX.RTM. NCMDW which is a 40% aqueous N-cocomorpholine oxide solution each of which is produced by the Armac Division of AKZO of Chicago, Ill. These materials are described in Brochure 68011, published by Armour Industrial Chemicals, P.O. Box 1805, Chicago, Ill. 60690. Other preferred amine oxides are n-undecyl dimethyl amine oxide and n-tridecyl dimethyl amine oxide.

The percentage of hypochlorite ion in the compositions of our invention may vary from about 1% up to about 20% for the desired effects to be produced using the diphenyl oxide derivative or diphenyl oxide derivative-amine-oxide ethyl norbornyl alkyl ethers compositions covered by our invention. The usual percent of alkali metal hypochlorite in solution is about 5%, the percentage of sodium hypochlorite in such mixtures as CLOROX.RTM. the registered trademark of the Clorox Corporation.

The perfume oil used in conjunction with the ethyl norbornyl alkyl ethers which, in turn, is used in conjunction wit the aqueous alkali metal hypochlorite solution must have such properties as to be able (1) to be compatible with the ethyl norbornyl alkyl ethers of our invention; (2) to impart to the resulting or "aqueous alkali metal hypochlorite" liquid or gel solution a pleasant aroma which harmonizes with the aroma of the ethyl norbornyl alkyl ethers; (3) to effect a substantial diminution or elimination of the disagreeable "hypochlorite" aroma which is imparted to surfaces (e.g., bleached laundry or the hands of the user which are in direct contact with the hypochlorite solution) on which known aqueous alkai metal hypochlorite solutions have been used; and (4) to impart to the surfaces with which such aqueous alkali metal hypochlorite solutions are in contact, a pleasant long lasting stable aroma. Examples of ingredients compatible with ethyl norbornyl alkyl ethers and suitable for the aforementioned purposes, that is, useable in conjunction with the hypochlorites, amine oxide derivatives and diphenyl oxide derivatives of our invention are as follows:

1. Cedryl alkyl ethers covered by U.S. Pat. No. 3,373,208 such as cedryl methyl ether;

It will be understood that a number of materials which impart to the citrusy floral aroma of ethyl norbornyl alkyl ethers of our invention additional eucalyptol-like, or minty or woody nuances will not be useful for our invention because they are, interalia, easily oxidized by the alkali metal hypochlorite in the system. Examples are 1,5,9-trimethyl-12-acetyl-cyclododecatriene-1,5,8 and 1,5,9-trimethyl-12-cyclodecadiene-1,8 covered by British Pat. No. 1,204,409.

A basic feature of our invention concerns the fact that the only detergent group needed or desirable in the composition of our invention is the class of diphenyl oxide derivatives defined according to the structure: ##STR60## wherein R.sub.1, R.sub.2, M.sub..alpha. and M.sub..beta. are defined, supra, taken alone or in conjunction with the class of morpholino and/or dimethyl C.sub.11 -C.sub.13 straight chain alkyl amine oxides defined according to the structure: ##STR61## More specifically, such detergents as sodium decyl ether sulfate, sodium myristyl ether sulfate, sodium lauryl ether sulfate and lithium lauryl ether sulfate are neither desired nor are they required. Furthermore, the well known hydrotropes employed in prior art compositions such as the well known family of clarifying agents comprising the alkali metal or alkali earth metal salts of mono- and polyalkylated benzene or naphthalene sulfonates such as sodium xylene or magnesium toluene sulfonate are again neither desired nor are they required in the compositions intended to be encompassed by the instant invention.

Another basic feature of our invention concerns the fact that when it is desired to have a gel phase composition, thickener agents may be employed in conjunction with the system; hypochlorite bleach-ethyl norbornyl alkyl ethers-diphenyl oxide derivative or plain oxide-derivative-amine oxide derivative (having the general structure ##STR62## and having the structure: ##STR63## of our invention.

Still another basic feature of our invention concerns the fact that the gel phase compositions including thickener agents are employed with the "premix" system: ethyl norbornyl alkyl ethers-diphenyl oxide derivative or diphenyl oxide derivative-amine oxide of our invention.

Thus, sodium palmitate, sodium stearate, sodium laurate, potassium palmitate, potassium stearate, potassium laurate, lithium palmitate, lithium stearate and/or lithium laurate or combinations of the foregoing may be added to the compositions of matter of our invention to provide a thickened gel-type hypochlorite bleach which is, in addition to being a semi-solid state, is unobviously, advantageously and unexpectedly stable over long periodss of time. Percentages of thickening agents such as sodium palmitate, sodium stearate, sodium laurate, potassium palmitate, potassium stearate, potassium laurate, lithium palmitate, lithium stearate or lithium laurate or combinations of these which may be used in the thickened compositions of our invention are from 1% by weight up to 12% by weight of the thickener based on the overall weight of hypochlorite bleach-diphenyl oxide derivative (or diphenyl oxide derivative-amine oxide)-ethyl norbornyl alkyl ethers composition of our invention. When it is merely desired to have a thickened "premix" the percentage of thickening agent may vary from about 5% up to about 40% by weight of thickener based on overall weight of "premix".
