Description
Background of the Invention
This invention relates to a detergent composition containing an organosilane compound. The detergent compositions of this invention are intended for use on hard, i.e. metallic and vitreous surfaces. More particularly, the inclusion of the hereindescribed organosilane compound in detergent compositions provides soil release benefits to surfaces washed with such compositions.
Detergent compositions intended for use on hard surfaces are continually being reformulated in order to improve their performance. Generally, detergent compositions are formulated to obtain optimum cleaning performance. Such endeavors have revolved around the use of different organic detergents as well as the use of detergent builders and various additives, e.g., enzymes, bleaches and pH modifiers. Considerations such as human safety, compatibility of components, and equipment safety have played a part in dictating what components can be used for improving existing detergent compositions.
Other attempts at insuring that hard surfaces are clean have involved the application of various surface coatings to such hard surfaces. For example, cookware which has been coated with Teflon provides a surface which is easier to clean. Thus, while soil continues to deposit upon the surface, its removal is easier by virtue of the coating. Unfortunately, such coatings are relatively expensive. Moreover, such a coating on glassware would be objectionable due to its appearance and/or feel. Since this kind of a coating must be applied by the manufacturer of the cookware or glassware, it must be permanent; this generally involves a relatively heavy coating with the consequent drawback in terms of cost, appearance, and/or feel.
It has been discovered that a very thin layer of a compound possessing soil release benefits can be supplied to metallic and vitreous surfaces by a detergent composition. Thus, when the detergent composition is used for cleaning or washing the hard surface, a thin semi-permanent coating of the compound is deposited. The amount of coating is sufficient to provide a soil release benefit to the surface, while at the same time, is not visible or expensive.
It accordingly is an object of this invention to provide detergent compositions which are capable of imparting a soil release benefit to surfaces contacted therewith.
It is another object of this invention to provide detergent compositions containing an organosilane which are able to efficiently provide soil release benefits to metallic and vitreous surfaces when applied thereto form a dilute wash or rinse solution.
Still another object of this invention is to provide a method for imparting a soil release benefit to hard surfaces.
As used herein, all percentages and ratios are by weight unless otherwise indicated.
Summary of the Invention
A detergent composition capable of imparting soil release benefits to metallic and vitreous surfaces contacted therewith consisting essentially of:
a. an organosilane having the formula ##STR1## or is siloxane oligomer thereof wherein R.sub.1 is an alkyl group containing 1 to 4 carbon atoms,
where x is 2 to 4, m is 1 to 20, and Z is hydrogen, an alkyl group containing 1 to 18 carbons or an acyl group containing 1 to 4 carbon atoms; R.sub.2 is an alkyl group containing 1 to 18 carbon atoms; a is 0 to 2; R.sub.3 is hydrogen or an alkyl group containing 1 to 18 carbon atoms; b is 1 to 3; c is 0 or 1; R.sub.4 is an alkyl, aryl or arylalkyl group containing 1 to 12 carbon atoms, a carboxy-substituted alkyl group containing 1 to 4 carbon atoms,
where x, m and Z are as defined above, or oxygen provided only one R.sub.4 is oxygen; R.sub.5 is an alkyl, aryl or arylalkyl group containing 1 to 22 carbon atoms; X is halide; and Y is nitrogen, sulfur or phosphorus; and
b. a water-soluble organic detergent selected from the group consisting of nonionic, zwitterionic and ampholytic detergents and mixtures thereof in a weight ratio of organosilane to detergent of from 2:1 to 1:10,000.
Description of the Invention
The subject invention relates to all manner of detergent compositions. As examples, may be mentioned the following: automatic dishwasher detergent compositions intended for home use, commercial dishwasher detergent compositions, light duty liquid detergent compositions, car wash detergent compositions, rinse aids, window cleaners, toilet bowl cleaners and oven cleaners. The previous listing is merely illustrative and is in no way limiting. Such compositions are further described hereinafter. The compositions may be used on any metallic or vitreous surface where a soil release benefit is desired. Examples of such surfaces are cooking utensils (e.g., metallic pots, pans and skillets), tableware (e.g., china, glasses, ceramic ware, and flatware), oven walls, automobiles, windows, and porcelain surfaces (e.g., bathtubs, sinks and toilet bowls).
The detergent compositions of this invention contain an organosilane and a water-soluble organic nonionic, zwitterionic and/or ampholytic detergent in a ratio of organosilane to detergent of from 2:1 to 1:10,000, preferably 1:1 to 1:500, most preferably 1:3 to 1:60. The organosilane has the following formula: ##STR2## or is a siloxane oligomer thereof wherein R.sub.1 is an alkyl group containing 1 to 4 carbon atoms,
where x is 2 to 4, m is 1 to 20, and Z is hydrogen, an alkyl group containing 1 to 18 carbon atoms or an acyl group containing 1 to 4 carbon atoms; R.sub.2 is an alkyl group containing 1 to 18 carbon atoms; a is 0 to 2; R.sub.3 is hydrogen or an alkyl group containing 1 to 18 carbon atoms; b is 1 to 3; c is 0 or 1; R.sub.4 is an alkyl, aryl or arylalkyl group containing 1 to 12 carbon atoms, a carboxy-substituted alkyl group containing 1 to 4 carbon atoms,
where x, m and Z are as defined above, or oxygen provided only one R.sub.4 is oxygen; R.sub.5 is an alkyl, aryl or arylalkyl group containing 1 to 22 carbon atoms; X is halide; and Y is nitrogen, sulfur or phosphorus. Preferably X is chloride or bromide and b is 1.
It should be understood that the R.sub.4 in the above formula and the formulae to follow may be the same or different. It should further be understood that when Y is S, there will be only one R.sub.4 substituent. Also, when one R.sub.4 is oxygen or, under acidic conditions, the anion of a carboxylic acid substituted alkyl, the counter ion X.sup.- is not extant. The 1 to 4 carbon atoms in the carboxy-substituted alkyl group is inclusive of the carboxyl group. The aryl or arylalkyl groups of R.sub.4 and R.sub.5 contain 6 to 12 carbon atoms and 6 to 22 carbon atoms, respectively.
Classes of organosilane compounds and their preparation which fit the above description follow. ##STR3## wherein R.sub.1 is a C.sub.1.sub.-4 alkyl group, b is from 1-3, R.sub.4 is a C.sub.1.sub.-12 alkyl, aryl or arylalkyl group, a carboxy-substituted C.sub.1.sub.-4 alkyl group,
where x is 2-4, m is 1-20, and Z is hydrogen, a C.sub.1.sub.-18 alkyl group or a C.sub.1.sub.-4 acyl group, or oxygen provided only one R.sub.4 is oxygen, R.sub.5 is a C.sub.4.sub.-22 alkyl, aryl or arylalkyl group, X is a halide, and Y is N, S or P.
When b is 3 and R.sub.4 is a C.sub.1.sub.-12 alkyl, aryl or arylalkyl group, the class of compounds represented by Formula I is prepared by the following route: ##STR4##
The trihalosilane (where the halogen is chlorine or bromine) is reacted with the allyl chloride at about 100.degree. C. for from 4 to 10 hours in the presence of a catalyst, e.g., chloroplatinic acid or platinum. The resultant gamma-halopropyltrihalosilane is reacted with a lower alcohol to produce the gamma-halopropyltrialkoxysilane. At least three equivalents of alcohol per equivalent of halopropyltrihalosilane are added slowly to the silane. The gamma-halopropyltrihalosilane may be dissolved in an inert solvent, preferably hexane or pentane. (See W. Noll, "Chemistry and Technology of Silanes," Academic Press, New York, 1968, page 81 for the alcoholysis of halosilanes.) One equivalent of the gamma-halopropyltrialkoxysilane is reacted with one equivalent of the tertiary amine, tertiary phosphine, or dialkylsulfide to produce the organosilane. An inert solvent, preferably of high dielectric constant, may be used. The reaction is carried out at temperatures of from 40.degree. C. to 120.degree. C. and a time of 2 to 10 hours for the reaction of the bromopropyltrialkoxysilane and 120.degree. C. to 150.degree. C. for 2 to 20 hours for the reaction of the chloropropyltrialkoxysilane.
The compounds of Formula I when at least one R.sub.4 is a carboxy-substituted C.sub.1.sub.-4 alkyl group are prepared in the same manner except for the last reaction step. Here, a tertiary amine, tertiary phosphine or dialkylsulfide having a carboxy-containing alkyl group(s) is reacted with the alpha, beta or gamma-haloalkyltrialkoxysilane at 50.degree. C. to 200.degree. C. for 2 hours to 20 hours. Such carboxy-substituted tertiary amines, tertiary phosphines, and dialkylsulfides are produced by reacting
with
in the presence of base at elevated temperatures, e.g. 50.degree. C. to 150.degree. C.
The compounds of Formula I when at least one R.sub.4 is
with X, m and Z as defined above are produced in the manner given above except for the last reaction step. Thus, alpha- beta- and gamma-haloalkyltrialkoxysilane is reacted with a tertiary amine, tertiary phosphine, or dialkylsulfide where at least one substituent is
the reaction takes place at a temperature of 50.degree. C. to 200.degree. C. and a time of from 2 to 10 hours.
Compounds of Formula I when one R.sub.4 is oxygen are prepared by following the reactions outlined above up to the last reaction step. At this point, a dialkyl amine, dialkyl phosphine or alkylthiol is reacted with the halosilane at 50.degree. C. to 200.degree. C. for from 4 to 10 hours and then with base to produce an intermediate tertiary amine, phosphine, or dialkyl sulfide. These intermediates are then reacted with H.sub.2 O.sub.2 at 20.degree. C. to 100.degree. C. or preferably O.sub.3 in an inert solvent at -80.degree. C. to 20.degree. C. to yield the organosilane.
When b is 2 in Formula I, a trihalovinylsilane of formula
(which is commercially available) is reacted with hydrogen bromide in the presence of peroxide or light to produce a beta-haloethyltrihalosilane. This compound is reacted with an alcohol and thereafter with an appropriate amine, phosphine, or sulfide in the manner discussed above for the preparation of the compounds of Formula I when b is 3.
When b is 1 in Formula I, the starting reactant is a commercially available trihalomethylsilane of formula
this silane is reacted with chlorine or, preferably a half mole of bromine and a half mole of chlorine in the presence of light (such as provided by an ordinary tungsten or fluorescent lamp). The resultant alpha-halomethyltrihalosilane is reacted with an alcohol and thereafter an appropriate amine, phosphine or sulfide in the manner discussed above with the compounds of Formula I when b is 3.

Compounds of Formulas I and II when R.sub.4 is an alkyl, aryl, arylalkyl group or oxygen are disclosed in British Pat. Nos. 686,068 and 882,053 and U.S. Pat. Nos. 2,955,127, 3,557,178, 3,730,701, and 3,817,739. Compounds of Formulas I and II when R.sub.4 is a carboxy-substituted alkyl group or
are disclosed in commonly assigned copending patent application "Organosilane Compounds" by Heckert and Watt U.S. Ser. No. 570,532, filed Apr. 22, 1975. (The disclosure of this application is herein incorporated by reference.) ##STR6## wherein R.sub.1 is C.sub.1.sub.-4 alkyl group, a is 0 to 2, R.sub.2 is a C.sub.1.sub.-18 alkyl group, R.sub.3 is a C.sub.1.sub.-18 alkyl group, R.sub.4 is a C.sub.1.sub.-12 alkyl, aryl or arylalkyl group, a carboxy-substituted C.sub.1.sub.-4 alkyl group,
where x is 2-4, m is 1-20, and Z is hydrogen, a C.sub.1.sub.-18 alkyl group or a C.sub.1.sub.-4 acyl group, or oxygen provided only one R.sub.4 is oxygen, R.sub.5 is a C.sub.1.sub.-22 alkyl, aryl or arylalkyl group, X is halide, and Y is N, S or P.
The compounds of Formula III when a is 0 and R.sub.4 is an alkyl, aryl or arylalkyl group are prepared by the following route: ##STR7##
The trihalosilane is reacted with an olefin at 100.degree. C. for 4 to 10 hours under a pressure of 50 to 300 psi. in the presence of a chloroplatinic acid or platinum catalyst to produce the trihaloalkylsilane. This reaction is reported by F. P. Mackay, O. W. Steward and P. G. Campbell in "Journal of the American Chemical Society," 79, 2764 (1957) and J. L. Speier, J. A. Webster and S. W. Barnes in Journal of the American Chemical Society, 79, 974 (1957). The trihaloalkylsilane is then halogenated in a known manner by treating it with halogen in the presence of light (such as that provided by ordinary tungsten or fluorescent lamps). Preferably, halogenation is carried out to only partial completion and a distillation is performed to recycle unreacted alkylsilane. The remaining reactions are the same as those described above in connection with the preparation of the compounds of Formula I.
When a is 1 or 2, the preparation of the compounds is essentially the same except for the use of an alkyl substituted silane as the starting reactant.
When R.sub.4 is a carboxy-substituted C.sub.1.sub.-4 alkyl group, oxygen or
where x is 2-4, m is 1-20, and Z is hydrogen, a C.sub.1.sub.-18 alkyl group, or a C.sub.1.sub.-4 acyl group, an appropriate amine, phosphine, or sulfide is used in the reaction step as discussed above for the preparation of similarly substituted compounds of Formula I.
The compounds that follow are illustrative of compounds of Formula III.

Commonly assigned copending patent application "Organosilane Compounds" by Heckert and Watt U.S. Ser. No. 570,537, filed Apr. 22, 1975 discloses the preparation of these compounds. (The disclosure of this application is herein incorporated by reference.) ##STR14## wherein R.sub.1 is a C.sub.1.sub.-4 alkyl group, a is 0-2, R.sub.2 is a C.sub.1.sub.-18 alkyl group, b is 1-3, R.sub.4 is a C.sub.1.sub.-12 alkyl, aryl or arylalkyl group, a carboxy-substituted C.sub.1.sub.-4 alkyl group,
where x is 2-4, m is 1-20, and Z is hydrogen, a C.sub.1.sub.-18 alkyl group or a C.sub.1.sub.-4 acyl group, or oxygen provided only one R.sub.4 is oxygen, R.sub.5 is a C.sub.1.sub.-22 alkyl, aryl or arylalkyl group, X is halide, and Y is N, S or P.
The compounds of Formula X are prepared by initially reacting (when a is 0 and b is 3) trihalosilane with an alcohol (R.sub.1 OH) at 0.degree. C. to 50.degree. C. for 1 to 10 hours to produce a trialkoxysilane. This silane is then reacted with an allylglycidylether ##STR15## in the presence of 0.01% to 0.1% chloroplatinic acid or platinum at 100.degree. C. for 2 to 10 hours. The resultant product ##STR16## is reacted with a tertiary amine, tertiary phosphine, or dialkylsulfide in the presence of an acid in an inert solvent at 60.degree. C. to 100.degree. C. for 1 to 10 hours to produce the compound of Formula X.
When a is 1 or 2, the preparation of the compounds is essentially the same except for the use of an alkyl substituted silane as the starting reactant.
When b is 2 in Formula X, a trihalovinylsilane of formula
(which is commercially available) is reacted with hydrogen bromide in the presence of peroxide or light to produce a beta-haloethyltrihalosilane. This compound is reacted with an alcohol, an allylglycidylether, and finally with an appropriate amine, phosphine, or sulfide in the manner discussed above for the preparation of the compounds of Formula X when b is 3.
When b is 1 in Formula X, the starting reactant is a commercially available trihalomethylsilane of formula
this silane is reacted with chlorine or, preferably a half mole of bromine and a half mole of chlorine in the presence of light (such as provided by an ordinary tungsten or fluorescent lamp). The resultant alpha-halomethyltrihalosilane is reacted with an alcohol, an allyglycidylether, and finally an appropriate amine, phosphine, or sulfide in the manner discussed above with the compounds of Formula X when b is 3.
The following compounds illustrate the compounds of Formula X.

U.S. Pat. No. 3,389,160 discloses compounds of Formula XIII when R.sub.4 is an alkyl, aryl, or arylalkyl group. Commonly assigned patent application, "Organosilane Compounds" by Heckert and Watt, U.S. Ser. No. 570,538, filed Apr. 22, 1975 discloses the preparation of the other compounds. (The disclosure of this application is herein incorporated by reference.)
Siloxane oligomers of the above organosilanes are also useful in the present invention. Such oligomers are formed from the monomers by the controlled addition of from 1 to 100 equivalents of water, preferably in an inert solvent such as alcohol, tetrahydrofuran, etc. As used herein, "oligomers" is used to mean a degree of polymerization of from 2 to 100, preferably 2 to 20. A higher degree of polymerization adversely affects the ability of the compound to bond itself to the hard surface and is for this reason avoided. Examples of siloxane oligomers having varying degress of polymerization are readily visualized from the above examples of organosilane monomers.
Water-soluble organic detergents selected from the group consisting of nonionic detergents, zwitterionic detergents, ampholytic detergents and mixtures thereof are used. U.S. Pat. No. 3,579,454 issued May 18, 1971 to Everett J. Collier, Col. 12, line 16 to Col. 13, line 64, (the disclosure of which is herein incorporated by reference) describes suitable detergents which fall within the abovedescribed classes. The nonionic detergents are preferred. The ratio of organosilane to organic detergent is from 2:1 to 1:10,000, preferably 1:1 to 1:500, most preferably 1:3 to 1:60. An amount of organosilane below 1:10,000 does not initially provide a noticeable soil release benefit and is, for this reason, avoided. (A benefit is realized from compositions containing a ratio of organosilane to detergent less than 1:10,000 after repeated washings due to a gradual buildup of deposited organosilane but is, for all practical purposes, too gradual to be of significance.) The upper level of organosilane in the composition is dictated by cost and the absence of any further noticeable soil release benefit. Generally, the amount of organosilane in a composition does not exceed 50% for a rinse aid type product and 10% for other detergent compositions.
When metallic or vitreous surfaces are contacted with a detergent composition containing the above-described organosilanes, a thin coating of the organosilane is attached to the surfaces. It is theorized that the positively charged organosilane is attracted to a negatively charged metallic or vitreous surface. The silicon atom in the organosilane forms a bond with the surface. The presence of the positive charge on the organosilane is necessary to allow the bonding to take place within a reasonable time period when the organosilane is applied from a dilute system such as is normally encountered in detergent compositions. The terminal alkyl groups attached to the positively charged compound provide the soil release benefits. It is believed that the organosilane compound polymerizes on the surface to form a thin coating of the polymer. The coating is responsible for imparting the soil release benefits to the surface. That is, a hard surface having on it the polymeric coating will be soiled; however, the soil is not tenaciously bound to the surface by virtue of the coating and for this reason is easily washed away.
Repeated washings can subsequently remove the polymeric coating. However, the soil release benefit is renewed by using the detergent compositions of this invention. The ability to provide a soil release benefit from a wash or rinse solution is especially beneficial in that it allows the consumer to efficiently and economically impart the benefit to a hard surface without adversely affecting its appearance.
Detergent compositions in which the organosilane compound is included are described in the following paragraphs.
Rinse Aid
Rinse aids are intended to be used in automatic dishwashing machines used either in the home or in commercial establishments. At the end of the cleaning cycle, it is desirable that the rinse water which is sprayed onto tableware and cooking utensils drain uniformly. Such uniform draining assures that spots of water do not remain behind. Invariably the water will contain dissolved substances which will leave behind a residue when dried. The inclusion of a rinse aid in the final rinse step insures that very little water is left behind on the dishes. The rinse aids of this invention consist essentially of from 0.1% to 50%, preferably 1% to 10% of the organosilane; from 5% to 99.9%, preferably 10% to 50% of the water-soluble organic nonionic detergent; and the balance water. Optionally from 1% to 30%, preferably 5% to 10% of a sequestering agent, e.g. phosphoric, glycolic, tartaric, succinic, citric, lactic, fumaric, or glyconic acid is included in the composition.

Optionally, from 1% to 10%, preferably 1% to 3% of magnesium sulfate is included in the composition.
Light Duty Liquid Detergent Composition
Light duty liquid detergent compositions are used for hand washing of cooking utensils and tableware. Such compositions consist essentially of from 0.01% to 10%, preferably 0.1% to 2% of the organosilane; from 10% to 90%, preferably 20% to 40% of the water-soluble nonionic, zwitterionic, and/or ampholytic detergent; and the balance water. Optionally, an electrolyte such as potassium chloride or sodium chloride is included in the composition at a level of from 0.5% to 5%, preferably 1% to 2%. Other optional components include a hydrotrope, e.g. toluene sulfonate, cumene sulfonate or xylene sulfonate at a level of from 1% to 20%, preferably 2% to 5%, and a lower alcohol, e.g. a C.sub.1-4 alcohol at a level of from 1% to 20%, preferably 3% to 10%.
Automatic Dishwashing Detergent Composition
A detergent composition intended to be used in the home in an automatic dishwashing machine is also encompassed by this invention. Such compositions consist essentially of from 0.01% to 5%, preferably 0.1% to 2% of the organosilane; from 0.1% to 15%, preferably 1% to 5% of the water-soluble nonionic detergent; from 5% to 60%, preferably 30% to 50% of a water-soluble organic or inorganic alkaline builder salt; and the balance inert filler salts. Suitable water-soluble organic and inorganic alkaline builder salts include the following: sodium tripolyphosphate, sodium citrate, sodium carbonate and sodium nitrilotriacetate.
Sodium sulfate and sodium chloride are suitable inert filler salts normally included in detergent compositions of this type.
These compositions can additionally contain from 7% to 35%, preferably 10% to 20%, of an alkali metal silicate having a SiO.sub.2 :M.sub.2 O ratio of from 3.6:1 to 1:2, preferably 2:1 to 3.2:1 wherein M is an alkali metal, e.g. sodium. The composition can optionally also contain a bleach in an amount sufficient to give the product an available chlorine content of from 0.5% to 10%, preferably 1% to 5%. Any suitable chlorine yielding bleach can be used. Examples are as follows: chlorinated trisodium phosphate, dichlorocyanuric acid; salts of chlorine substituted cyanuric acid; 1,3-dichloro-5,5-dimethylhydantoin; paratoluene sulfodichloroamide; trichloromelamine; N-chlorosucinimide; N,N'-dichloroazodicarbonamide; N-chloroacetyl urea; N,N'-dichlorobiuret; chlorinated dicyandiamide; sodium hypochlorite; calcium hypochlorite; and lithium hypochlorite.
Commercial Automatic Dishwashing Detergent Composition
A commercial dishwashing composition consists essentially of from 0.01% to 5%, preferably 0.1% to 2% of the organosilane; from 0.1% to 15%, preferably 1 % to 5 % of the water-soluble nonionic detergent; from 5% to 60%, preferably 30 % to 50 % of a water-soluble organic or inorganic alkaline builder salt; from 10% to 40%, preferably 10% to 30% of an alkali metal base; and the balance inert filler salts.

The following examples are illustrative of this invention.
Example I
The organosilanes of this invention are tested for their ability to provide a soil release benefit to hard surfaces in the manner described immediately below.
A solution of 0.003% organosilane and 0.01% tallow alcohol ethoxylated with 9 moles of ethylene oxide in distilled water is prepared. The solution has a temperature of 55.degree. C. A clean glass slide is dipped into the solution and held there for 10 minutes. The solution is continuously mixed while the glass slide is being treated. After the 10 minute hold time, the glass slide is removed and rinsed with tap water having a temperature of about 15.degree. C. The rinsed slide is dried at 72.degree. C. for 20 minutes.
Next the slide is soiled by dipping it into an oatmeal slurry for 15 seconds and baking it for 20 minutes at 72.degree. C. Thereafter, the slide is washed with distilled water in a Tergotometer for 3 minutes at 55.degree. C. The resultant slide is dyed with a solution of iodide and potassium iodide in water to facilitate its grading.
The slide is graded visually and assigned a number ranging from 0 (equal to an untreated glass slide, i.e., the control) to 4 (a totally clean slide). Intermediate grades of 1 (slightly better than control), 2 (a definite noticeable improvement) and 3 (slide is almost clean) are used.
Each organosilane is tested 5 times in the manner above described and its average is recorded. The individual organosilanes and their grades are reported below.
The addition of different water-soluble organic detergents as hereinbefore described to the solution at levels of 2:1 to 1:10,000 organosilane to detergent does not alter the relative grades of above. That is, such solutions still impart a noticeable soil release benefit to the glass slides. In particular, sodium 3-dodecylaminopropionate or 3-(N,N-dimethyl-N hexadecylammonio)propane-1-sulfonate and the organosilane when tested as above give the same relative grades as above reported for the nonionic detergent.
The following examples are illustrative of detergent compositions containing the organosilanes of this invention. All impart a noticeable solid release benefit to metallic and vitreous surfaces washed or rinsed therewith.
when
or
is substituted for the organosilane of Example II, substantially the same results are obtained.
Substantially the same results are obtained from the above composition when the organosilane is replaced by a similar compound having a phosphorous atom or a sulfur atom (and only one methyl group) in place of the nitrogen atom.
When the above organosilane is replaced with
or
substantially the same results are obtained.
Replacement of the above organosilane with similar compounds having a phosphorous atom and a sulfur atom (and only one ethyl group) in place of the nitrogen atom gives substantially the same results.
When
or
is substituted for the organosilane of Example VII, substantially the same results are obtained.
The use of similar organosilanes having a phosphorous or sulfur atom (and only one ethyl group) in place of the nitrogen atom results in satisfactory soil release benefits.
Substantially the same results are obtained from the above composition when the organosilane is replaced by a similar compound having a phosphorous atom or a sulfur atom (and only one methyl group) in place of the nitrogen atom.
The use of organosilane compounds having a phosphorous atom or a sulfur atom (and only one propyl group) in place of the nitrogen atom results in satisfactory products.
when
or
is substituted for the organosilane of Example XII, substantially the same results are obtained.
Substitution of
or
for the above organosilane gives substantially the same results.
Satisfactory results are obtained when the organosilanes of Examples II - XIV are replaced by any of the organosilanes of Example I. Siloxane oligomers of the organosilanes of Examples I - XIV having a degree of polymerization of from 2 to 100 when substituted in the above examples for the organosilane monomer also give a noticeable soil release benefit to surface washed or rinsed therewith.
The compositions of this invention are generally diluted with water during usage. Under normal usage conditions, from 0.2 to 20 p.p.m. of organosilane is found in the wash or rinse solution. Surprisingly, even from such a low concentration, the organosilane molecule of this invention deposits itself upon hard surfaces in an amount sufficient to provide a noticeable soil release benefit. As previously discussed, it is believed the positively charged atom in the molecule is largely responsible for the necessary deposition to take place under such dilute conditions.
In another aspect of this invention, the organosilane is used in a commercial dishwashing machine as part of the final rinse cycle and free of any organic detergent. Thus, the organosilane is metered into the rinse water at a level sufficient to provide a soil release benefit (i.e. about 0.2 to 20 p.p.m. organosilane) and applied to the previously washed cooking utensils and tableware.
