Use of 2,4,6-Trimethylcyclohexanemethanol and Derivatives for Augmenting or Enhancing the Aroma or Taste of Smoking Tobacco and Smoking Tobacco Articles

The instant invention provides novel 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof having the generic structure: ##STR2## wherein R is hydrogen or acetyl and wherein the dashed line is a carbon-carbon single bond or a carbon-carbon double bond and uses thereof for their organoleptic properties in consumable materials.

Chemical compounds which can provide sweet, spicy; fresh, green, floral; fruity; Freesia-like and methyl ionone-like aromas with geranium and ionone-like topnotes and minty-rose undertones are desirable in the art of perfumery. Many of the natural materials which provide such fragrances and contribute such desired nuances to perfumery compositions are high in cost, unobtainable at times, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.

By the same token, materials which can provide herbaceous, spicy, floral, green, minty, fruity, fresh, ionone-like and camphoraceous flavor characteristics, as well as aroma characteristics, are desirable in applying the art of flavoring to foodstuffs, toothpastes, chewing gums and medicinal products. Many of the natural materials which provide such flavor notes and contribute desired nuances to flavoring compositions are high in cost, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.

By the same token, sweet, floral, green, weedy and herbaceous aromas prior to and on smoking in the main stream and in the side stream are desirable in the smoking tobacco art for enhancing certain specialty smoking tobacco-like notes.

There is, accordingly, a continuing effort to find synthetic materials which will replace, enhance or augment the essential flavor and fragrance notes provided by natural essential oils or compositions thereof. Unfortunately, many of these synthetic materials either have the desired nuances only to a relatively small degree or else contribute undesirable or unwanted odor to the compositions.

The compound having the structure: ##STR3## and the compound having the structure: ##STR4## are reported by Sopov and Kovner at Zh. Obsch. Khim. 34, 1492-6 (1964) as abstracted in Chem. Abstracts, Vol. 61, 5529b.

The Sopov and Kovner reference does not, however, disclose organoleptic uses of the compounds having the structures: ##STR5##

In recent years, compounds having the structures: ##STR6## have been found to be useful in compounding various perfume formulations. These lower adjacent methyl homologs of the compounds having the structure: ##STR7## have properties from an organoleptic standpoint considered to be different in kind, rather than in degree, from the compounds defined by the structure: ##STR8## These compounds defined according to the structure: ##STR9## have properties which are unobvious, unexpected and advantageous over the prior-used compounds having the structures: ##STR10##

Furthermore, insofar as their organoleptic uses are concerned, the compounds of the instant invention have unexpected, unobvious and advantageous properties over any other compounds of the prior art.

It has now been determined that certain 2,4,6-Trimethylcyclohexenemethanol derivatives and the 2,4,6-Trimethylcyclohexenemethanol itself having the generic structure: ##STR23## wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond and R is hydrogen or acetyl are capable of imparting a variety of flavors and fragrances to various consumable materials and are also capable of augmenting or enhancing a variety of flavors and fragrances of various consumable materials.

Briefly, our invention contemplates augmenting or enhancing the flavors and/or fragrances of such consumable materials as perfumes, perfumed articles (e.g., solid or liquid anionic, cationic or non-ionic detergents or dryer-added fabric softeners), colognes, foodstuffs, chewing gums, toothpastes, medicinal products and smoking tobaccos by adding thereto a small but effective amount of at least one of the compounds having the generic structure: ##STR24## wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond and R is hydrogen or acetyl.

The 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention augment or enhance camphoraceous, herbaceous, spicy, floral, green, minty, fruity, fresh and ionone-like flavor and aroma characteristics insofar as augmenting or enhancing the aroma or taste of foodstuffs, toothpastes, medicinal products (e.g., cough drops) and chewing gum.

The 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention also augment or enhance the sweet, spicy; fresh, green, floral; fruity; Freesia; methyl ionone-like aromas and geranium and ionone topnotes and minty-rose under-tones of perfumes, perfumed articles (such as cationic, anionic and non-ionic detergents and dryer-added fabric softener articles) and colognes.

The 2,4,6-Trimethylcyclohexanemethanol and derivatives of our invention also augment or enhance the sweet, floral, green, weedy and herbaceous aroma nuances of smoking tobacco, both prior to and on smoking, both in the main stream and in the side stream.

Examples of the 2,4,6-Trimethylcyclohexanemethanol and derivatives of our invention and their organoleptic characteristics are as follows:

The 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention can be produced by first forming 2,4,6-Trimethyl-3-cyclohexene-1-carboxaldehyde by reaction of an alpha, beta-unsaturated aldehyde with a conjugated diene according to the reaction: ##STR29## This reaction product is then reduced using an alkali metal borohydride or hydrogen and a Raney nickel catalyst. Also lithium aluminum hydride and an alkali metal BH.sub.3 CN can be used.

The mole ratio of the resulting isocyclocitral to alkali metal borohydride may vary from 5:1 to 2:1 but is preferably 4:1. The reaction temperature for reduction may range from 40.degree. C. up to 80.degree. C. The solvents used in this reduction reaction are polar solvents such as tetrahydrofuran, isopropyl alcohol, methyl alcohol, ethyl alcohol and dioxane.

The procedure for carrying out the reaction is critical insofar as one particular aspect is concerned; that is, that the isocyclocitral is to be added to a mixture of alkali metal borohydride in solvent.

Regarding the catalytic hydrogenation of the 2,4,6-Trimethyl-3-cyclohexene-1-carboxaldehyde, Raney nickel is the preferred catalyst. The temperature of reaction may vary from 60.degree. C. up to 100.degree. C. with a temperature of 80.degree. C. being preferred. The hydrogen pressure when using hydrogen over a Raney nickel catalyst may vary up to 500 psig.

The 2,4,6-Trimethyl-3-cyclohexene-1-methanol prepared by the reduction of the 2,4,6-Trimethyl-3-cyclohexene-1-carboxaldehyde may be either further reduced to form the compound having the structure: ##STR30## or it may be acylated using, for example, acetic anhydride to form the compound having the structure: ##STR31## In addition, the compound having the structure: ##STR32## may also be acylated thereby producing the compound having the structure: ##STR33## Although the preferred reagent for such acylation is acetic anhydride, acetyl chloride in a base such as pyridine, triethylamine or potassium carbonate may be used.

When using acetic anhydride as an acylating agent, this reaction can be carried out in the presence of mineral acids such as phosphoric acid, sulfuric acid or anhydrous hydrochloric acid at temperatures of from 40.degree. C. up to 80.degree. C. When no catalyst is used, the temperature range should be from 80.degree. C. up to 120.degree. C. Inert solvents in this reaction can be used, such as toluene, dichlorobenzene or xylene, or the reaction can be carried out without the use of a solvent.

The mole ratio of an acylating agent:starting material is 1:1 up to 2:1 with a mole ratio of 1.5:1 being preferred.

In carrying out the hydrogenation using Raney nickel, 5% or 10% palladium or platinum on carbon can be used to replace the Raney nickel or rhodium catalyst may be used. Raney nickel is preferred as the catalyst since it is the least expensive to use and since the temperatures when using same are relatively low. The reaction pressure may vary during the hydrogenation from 500 psi up to 3,600 psi with 1,000 psi pressure being preferred. The overall reaction sequence as described above is set forth as follows: ##STR34##

The individual 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention can be obtained in pure form or in substantially pure form by conventional purification techniques. Thus, the products can be purified and/or isolated by distillation, extraction, crystallization, preparative chromatographic techniques (column chromatography and vapor phase chromatography) and the like. It has been found desirable to purify the 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention by fractional distillation in vacuo.

When the 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof our invention are used as food flavor adjuvants, the nature of the co-ingredients included with said 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention in formulating the product composition will also serve to alter modify, augment or enhance the organoleptic characteristics of the ultimate foodstuff treated therewith.

As used herein in regard to flavors, the terms "alter", "modify" and "augment" in their various forms means "supplying or imparting flavor character or note to otherwise bland, relatively tasteless substances or augmenting the existing flavor characteristic where a natural flavor is deficient in some regard or supplementing the existing flavor impression to modify its quality, character or taste".

The term "enhance" is used herein to mean the intensification of a flavor or aroma characteristic or note without the modification of the quality thereof. Thus, "enhancement" of a flavor or aroma means that the enhancement agent does not add any additional flavor note.

As used herein, the term "foodstuff" includes both solid and liquid ingestible materials which usually do, but need not, have nutritional value. Thus, foodstuffs include soups, convenience foods, beverages, dairy products, candies, vegetables, cereals, soft drinks, snacks, and the like.

As used herein, the term "medicinal product" includes both solids and liquids which are ingestible, non-toxic materials which have medicinal value such as cough syrups, cough drops, aspirin and chewable medicinal tablets.

The term "chewing gum" is intended to mean a composition which comprises a substantially water insoluble, chewable plastic gum base such as chicle, or substitutes therefor, including jelutong, guttakay, rubber or certain comestible natural or synthetic resins or waxes. Incorporated with the gum base in admixture therewith may be plasticizers or softening agents, e.g., glycerine, and a flavoring composition which incorporates one or more of 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention, and in addition, sweetening agents which may be sugars, including sucrose or dextrose and/or artificial sweeteners such as cyclamates or saccharin. Other optional ingredients may also be present.

Substances suitable for use herein as co-ingredients or flavoring adjuvants are well known in the art for such use, being extensively described in the relevant literature. It is a requirement that any such material be "ingestibly" acceptable and thus non-toxic and otherwise non-deleterious particularly from an organoleptic standpoint whereby the ultimate flavor and/or aroma of the consumable material used is not caused to have unacceptable aroma and taste nuances. Such materials may in general be characterised as flavoring adjuvants or vehicles comprising, broadly, stabilizers, thickeners, surface active agents, conditioners, other flavorants and flavor intensifiers.

The specific flavoring adjuvant selected for use may be either solid or liquid depending upon the desired physical form of the ultimate product, i.e., foodstuff, whether simulated or natural, and should, in any event, (i) be organoleptically compatible with 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention by not covering or spoiling the organoleptic properties (aroma and/or taste) thereof; (ii) be non-reactive with 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention and (iii) be capable of providing an environment in which the 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention can be dispersed or admixed to provide a homogeneous medium. In addition, selection of one or more flavoring adjuvants, as well as the quantities thereof will depend upon the precise organoleptic character desired in the finished product. Thus, in the case of flavoring compositions, ingredient selection will vary in accordance with the foodstuff, chewing gum, medicinal product or toothpaste to which the flavor and/or aroma are to be imparted, modified, altered or enhanced. In contradistinction, in the preparation of solid products, e.g., simulated foodstuffs, ingredients capable of providing normally solid compositions should be selected such as various cellulose derivatives.

As will be appreciated by those skilled in the art, the amount of 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention employed in a particular instance can vary over a relatively wide range, depending upon the desired organoleptic effects to be achieved. Thus, correspondingly, greater amounts would be necessary in those instances wherein the ultimate food composition to be flavored (e.g., with a spice flavor or a specific black pepper-like flavor) is relatively bland to the taste, whereas relatively minor quantities may suffice for purposes of enhancing the composition merely deficient in natural flavor or aroma. The primary requirement is that the amount selected be effective, i.e., sufficient to alter, modify or enhance the organoleptic characteristics of the parent composition, whether foodstuff per se, chewing gum per se, medicinal product per se, toothpaste per se, or flavoring composition.

The use of insufficient quantities of 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention will, of course, substantially vitiate any possibility of obtaining the desired results while excess quantities prove needlessly costly and in extreme cases may disrupt the flavor-aroma balance, thus proving self-defeating. Accordingly, the terminology "effective amount" and "sufficient amount" is to be accorded a significance in the context of the present invention consistent with the obtention of desired flavoring effects.

Thus, and with respect to ultimate food compositions, chewing gum compositions, medicinal product compositions and toothpaste compositions, it is found that quantities of 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention ranging from a small but effective amount, e.g., 0.05 parts per million up to about 500 parts per million based on total composition, are suitable. Concentrations in excess of the maximum quantity stated are not normally recommended since they fail to provide commensurate enhancement of organoleptic properties. In those instances wherein the 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention are added to the foodstuff as an integral component of a flavoring composition, it is, of course, essential that the total quantity of flavoring composition employed be sufficient to yield effective 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof concentration in the foodstuff product.

Food flavoring compositions prepared in accordance with the present invention preferably contain the 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention in concentrations ranging from about 0.025% up to about 15% by weight based on the total weight of the said flavoring composition.

The composition described herein can be prepared according to conventional techniques well known as typified by cake batters and fruit drinks and can be formulated by merely admixing the involved ingredients within the proportions stated in a suitable blender to obtain the desired consistency, homogeneity of dispersion, etc. Alternatively, flavoring compositions in the form of particulate solids can be conveniently prepared by mixing the 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention with, for example, gum arabic, gum tragacanth, carrageenan and the like, and thereafter spray-drying the resultant mixture whereby to obtain the particular solid product. Pre-prepared flavor mixes in powder form, e.g., a fruit-flavored powder mix, are obtained by mixing the dried solid components, e.g., starch, sugar and the like, and 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention in a dry blender until the requisite degree of uniformity is achieved.

It is presently preferred to combine with the 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention, the following adjuvants: Oil of Cubeb; Phellandrene; beta-Phellandrene; Oil of Coriander; Oil of Pimento Leaf, Oil of Patchouli; Natural Lemon Oil; Acetaldehyde; .alpha.-Terpineol, Citral; Carvone; Terpinolene; .alpha.-Terpinene; Diphenyl; .alpha.-Fenchyl Alcohol; Cineole; Limonene; Linalool; Geranyl Acetate; Nootkatone; Neryl Acetate; Heliotropin; Maltol, Vanillin; Ethyl Maltol; Ethyl Vanillin; Anisaldehyde; Alpha Pinene; Beta-Pinene; Beta-Caryophyllene; Dihydrocarveol; Piperonal; Piperine; Chavicine; Piperidine; Oil of Black Pepper; Black Pepper Oleoresin; Capsicum; Oil of Nutmeg; Cardamom Oil; Clove Oil; Spearmint Oil; Oil of Peppermint; and C.sub.10 -Terpinyl Ethers as described in Application for United States Patent, Ser. No. 872,937 filed on Jan. 27, 1978, now U.S. Pat. No. 4,131,687 issued on Dec. 26, 1978 (such as fenchyl ethyl ethers).

The 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention can be used to contribute sweet, spicy, fresh green, floral, fruity, Freesia-like and methylionone-like aromas with geranium and ionone-like topnotes and minty-rose undertones to perfumes, perfumed articles and colgones. As olfactory agents, the 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention can be formulated into or used as components of a "perfume composition" or can be used as components of a "perfumed article" or the perfume composition may be added to perfumed articles.

The term "perfume composition" is used herein to mean a mixture of organic compounds including, for example, alcohols, aldehydes, ketones, nitriles, ethers, lactones, natural essential oils, synthetic essential oils and frequently hydrocarbons which are admixed so that the combined odors of the individual components produce a pleasant or desired fragrance. 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) top-notes which are usually low-boiling, fresh-smelling materials.

In perfume compositions, the individual component will contribute its particular olfactory characteristics, but the overall effect of the perfume composition will be the sum of the effects of each of the ingredients. Thus, the individual compounds of this invention, or mixtures thereof, can be used to alter the aroma characteristics of a perfume composition, for example, by highlighting or moderating the olfactory reaction contributed by another ingredient in the composition.

The amount of 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention which will be effective in perfume compositions depends on 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 0.5% of 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of this invention, or even less, can be used to impart an interesting spicy, fruity, Freesia-like and/or green aroma to soaps, liquid and solid cationic, anionic and nonionic detergents, cosmetic, powders, liquid and solid fabric softeners, optical brightener compositions, and other products. The amount employed can range up to 50% or higher and will depend on considerations of cost, nature of the end product, and the effect desired on the finished product and particular fragrance sought.

The 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of this invention can be used alone or in a perfume composition as an olfactory component in detergents and soaps, space odorants and deodorants; perfumes; colognes, toilet waters; bath salts; hair 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 powder, and the like. When used as an olfactory component of a perfumed article, as little as 0.01% of one or more of 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof will suffice to impart an interesting spicy, fruity, Freesia-like and/or green aroma. Generally no more than 0.5% is required.

In addition, the perfume composition can contain a vehicle or carrier for 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof alone or with other ingredients. The vehicle can be a liquid such as an alcohol such as ethanol, a glycol such as propylene glycol, or the like. The carrier can be an absorbent solid such as a gum or components for encapsulating the composition such as gelatin which can be used to form a capsule wall surrounding the perfume oil, by means of coacervation.

An additional aspect of our invention provides an organoleptically improved smoking tobacco product and additives therefor including methods of making the same which overcome problems heretofore encountered in the creation or enhancement of specific desired natural tobacco-like notes, particularly hay-like notes. Such notes, both prior to and on smoking, in both the main stream and the side stream, may now be readily controlled and maintained at the desired uniform level regardless of variations in the tobacco components of the blend; or the nature of the filter used in conjunction with the smoking tobacco article.

This invention further provides improved tobacco additives and additives for materials used in the fabrication of tobacco articles (particularly smoking tobacco articles) and methods whereby desirable hay-like notes may be imparted to smoking tobacco products and may be readily varied and controlled to produce the desired uniform flavoring characteristics.

In carrying out this aspect of our invention, we add to smoking tobacco materials or a suitable substitute therefor (e.g., dried lettuce leaves) an aroma and flavor additive containing as an active ingredient, one or more of 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention.

In addition to 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention, other flavoring and aroma additives may be added to the smoking tobacco material or substitute therefor either separately or in mixture with one or more of the 2,4,6-Trimethylcyclohexanemethanol and derivatives of our invention:

An aroma and flavoring concentrate containing one or more of 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention and, if desired, one or more of the above-indicated additional flavoring additives may be added to the smoking tobacco material, to the filter or to the leaf or paper wrapper or to a filter which is part of the smoking article. The smoking tobacco material may be shredded, cured, cased and blended tobacco material or reconstituted tobacco material or tobacco substitutes (e.g., lettuce leaves) or mixtures thereof. The proportions of flavoring additives may be varied in accordance with taste, but insofar as enhancement or the imparting of hay-like notes prior to and on smoking, in both the main stream and the side stream, we have found that satisfactory results are obtained if the proportion by weight of the sum total of 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of this invention to smoking tobacco material is between 50 ppm and 1500 ppm (0.005%-0.15%) of the active ingredients to the smoking tobacco material. We have further found that satisfactory results are obtained if the proportions by weight of the sum total of 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof used to flavoring material is between 0.05:1 and 0.50:1.

Any convenient method for incorporating the 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention in the tobacco product may be employed. Thus the 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention taken alone or along with other flavoring additives may be dissolved in a suitable solvent such as food grade ethanol, pentane, diethyl ether and/or other volatile organic solvents, and the resulting solution may either be sprayed on the cured, cased and blended tobacco material; or the tobacco material or filter may be dipped into such solution. Under certain circumstances, a solution of one or more 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof taken alone or taken further together with other flavoring additives as set forth above, may be applied by means of a suitable applicator such as a brush or roller on the paper or leaf wrapper for the smoking product, or it may be applied to the filter by either spraying or dipping or coating.

Furthermore, it will be apparent that only a portion of the tobacco or substitute therefor need be treated, and the thus-treated tobacco may be blended with other tobaccos before the ultimate tobacco product is formed. In such cases, the tobacco treated may have one or more 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention in excess of the amounts or concentrations above indicated so that when blended with other tobaccos, the final product will have the percentage within the indicated range.

While our invention is particularly useful in the manufacture of smoking tobacco such as cigarette tobacco, cigar tobacco and pipe tobacco, other tobacco products formed from sheeted tobacco dust or fines may also be used. As stated supra, 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention can be incorporated with materials such as filter tip materials, seam paste, packaging materials and the like which are used along with the tobacco to form a product adapted for smoking. Furthermore, 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention can be added to certain tobacco substitutes of natural or synthetic origin (e.g., dried lettuce leaves) and, accordingly, by the term "tobacco" as used throughout this specification is meant any composition intended for human consumption, by smoking or otherwise, whether composed of tobacco plant parts or substitute materials or both.

It will thus be apparent that 2,4,6-Trimethylcyclohexanemethanol and derivatives thereof of our invention can be utilized to alter, modify, augment or enhance sensory properties, particularly organoleptic properties, such as flavor(s) and/or fragrance(s) of a wide variety of consumable materials.

The following examples serve to illustrate our invention, and this invention is to be considered restricted thereto only as indicated in the appended claims.
