Description

SHAMPOGS Armin l-liestand, Binningen, Switzerland, assignor to Cilia Limited, Basel, Switzerland, a Swiss company No Drawing. Filed June 22, 1965, Ser. No. 466,061 Claims priority, application Switzerland, Oct. 25, 196i, 12,333/61 14 Claims. (Cl. 252-152) This is a continuation-in-part of application Ser. No. 232,608, filed Oct. 23, 1962, now abandoned.

The present invention provides shampoos that contain (a) A cationic compound containing at least one aliphatic hydrocarbon residue with more than 7, preferably 11 to 18, carbon atoms, as well as at least one tertiary or quaternary nitrogen atom present in salt-like form, and

(b) A water-soluble reaction product of an alcohol with 6 to 11 carbon atoms having a branched hydrocarbon radical and whose main chain contains at least 5 carbon atoms, with up to 15 molecular proportions of ethylene oxide.

It is known to use in shampoos simultaneously cationic compounds andv ethylene oxide adducts derived from linear higher fatty alcohols, for example n-dodecyl alcohol. Compared with such known shampoos the preparations of the invention are distinguished by a vastly superior lathering power and stability of the lather.

The outstanding lathering power of the new shampoos is all the more surprising as the above-mentioned cationic components (a) and the non-ionic components (b) by themselves either have a completely inadequate or no lathering power at all on hair.

It is another surprising advantage of the preparations of the invention that their washing power is such that it ensures on one hand a completely adequate washing effect on dirty hair, while on the other hand this is not accompanied by an undesirable defatting, drying, irritation or the like of the hair or scalp respectively such as is connected with an excess washing effect.

The socalled poissage-efiect which often occurs on application of shampoos containing cationic ingredients and which finds its expression in hair sticking together, more especially when it is subsequently rinsed, practically does not crop up with the present shampoos. It is another of their advantages that they have no unpleasant odour of their own or one that would render perfuming difiicult.

Hair treated with one of the new shampoos has a soft, flufiy feel and a pleasing silky sheen, it has no electrostatic charge and is easy to brush and comb.

The store-mentioned valuable properties of the hair are obtained more especially with those preparations of the invention which contain a hair shampoo preparation which contains (1) As cation active component a member selected from the group consisting of (a) a tertiary amine salt of the compound of the formula R4 R,le lN R, N

3,322,676 Patented May 30, 11967 in which Where A and A each represents a member selected from the group consisting of a hydrogen atom, the

methyl radical and the hydroxyethyl radical with a cosmetically acceptable acid,

(b) A tertiary amine salt of a compound of the formula RrNR -N-R 0H, CH3

in which R represents an aliphatic hydrocarbon radical with 11 to 18 carbon atoms, and

R represents a member selected from the group consistting of an alkylene radical containing 2 to 6 carbon atoms and the radical -CH CHOH-CH with a cosmetically acceptable acid,

(0) A quaternary ammonium salt of a compound of the formulae set forth above under (a) and (b) with a member selected from the group consisting of methyl iodide, dimethyl sulfate, benzyl chloride, a polyglycol chloride containing at most 6 carbon atoms and ethylene chlorohydrine,

(d) A compound of the formula N-OH2 RW- (3H2 N if in which R represents a hydrocarbon radical With 11 to 18 carbon atoms, and R represents a member selected from the group consisting of a hydrogen atom, a radical of the formula -CH -CH -NH and a radical of the formula CHZCH2-OH (2) As nonionic component a water-soluble reaction product of an alcohol which contains 6 to 11 carbon atoms, whose hydrocarbon radical is branched and whose main-chain contains at least carbon atoms, with at most 15 mols of ethylene oxide,

(3) Water, and

(4) A cosmetically acceptable acid in an amount which is sufficient to effect in the aqueous shampoo preparation a pH-value of 3.0 to 7.0, and in which shampoo preparation the weight ratio of component (1) to component (2) ranges from 1:1 to 1:100.

With regard to their non-ionic ingredient (2) those preparations of the invention deserve to be given preference which contain a compound obtained by reacting 5 to molecular proportions of ethylene oxide with 1 molecular proportion of the alcohol referred to above under (2).

Particularly useful are those new mixtures whose nonionic ingredient has been prepared by adding 5 to 10 molecular proportions of ethylene oxide on to a secondary or preferably primary aliphatic alcohol of the kind described above.

Surprisingly, it has further been found that those shampoos of the invention possess particularly good properties and are distinguished, for example, by the absence of an unpleasant odour of their own even when examined critically, which contain as the non-ionic ingredient an ethylene oxide adduct which, before being incorporated in the shampoo, has been subjected to a special purifying treatment, for example by expulsion of undesired substances by distillation. Such a purification operation may consist, for example, in the distillative expulsion from a commercial ethylene oxide adduct under a very good water-jet vacuum at about 160 to 180 C. or in a fallingfilm distillation. It has further been found that particularly valuable, purified products are obtained in this manner when the commercial ethylene oxide adduct liquefied by heating is mixed in the undiluted form with a sufficiency of an inorganic or organic acid to establish a weakly acidic reaction of the resulting solution of 10% strength. This may be achieved with concentrated acids, such as phosphoric acid of 85% strength, lactic acid of 90% strength, tartaric acid or citric acid. It is of special advantage to heat the batch to a distillation temperature corresponding to the boiling point of the monohydroxyethyl compound or of the monoglycol or diglycol ether of the alcohol selected as starting material.

The amine compound on which the cationic ingredient (a) is based can be prepared by methods known in the art from the corresponding amine bases or their reaction products with fatty acids or derivatives thereof, hydroxyalkylation agents, for example ethylene oxide, alkylating and acylating agents, for example chloracetic acid or with derivatives thereof, and then converted in known manner by reaction with acids into the amine salts or with quaternating agents into the quaternary ammonium salts. Suitable starting materials for the manufacture of the cationic ingredient to be used according to the invention are tertiary amines of the formula wherein R represents an alkyl with l2-l6 carbon atoms, for example, N-dimethyl-dodecylamine, N-dimethyl-hexadecylamine and their hydroxyalkylation products, also diamines, for example N-dodecyl-ethylenediamine, tetramethylenediamine and hexamethylenediamine, N-octadecyl-ethylenediamine, N-dodecyl-propylenediamine, N- hexadecyl-propylenediamine and N-octadecyl-propylenediamine; also reaction products of such N-alkylene-polyamines with an alkylene oxide, such as ethylene oxide or propylene oxide, for example N-dodecyl-N:N'-dihydroxyethyl-ethylenediamine, N dodecyl-N:N'-dihydroxyethylpropylenediamine and N-octadecyl-N:N-dihydroxyethylpropylenediamine. Furthermore, there may be used as starting material for the cationic ingredient (a) contamed in the new preparations the following: mono-acylation products from 1 molecular proportion of a higher fatty acid (for example lauric, myristic, palmitic, stearic or oleic acid) and 1 molecular proportion of an alkylenepolyamine such as ethylenediamine or propylcnediamine and diethylenetriamine; likewise suitable are reaction products of these monoacyl derivatives with a halohydrin or alkylene oxide, such as N-lauroyl-N-hydroxyethylethylenediamine, N palmitoyl-N'-hydroxyethyl-ethylenediamine, N-stearoyl-N-hydroxyethyl-ethylenediamine, N- lauroyl-N'-hydroxyethyl-propylenediamine and N-lauroylhydroxyethyl-diethylenetriamine.

Those compounds of the general Formula 1, which are used in the form of their salts as cationic ingredient (a) of the new preparations and contain a radical of the formula (in which formula A and A have the above meanings) are accessible by reacting the amine concerned with chloracetic acid or with a compound of the general formula (in which A and A have the above meanings), more especially with chloracetamide or NzN-[di-(fi-hydroxyethyl) l-chloracetamide.

The conversion of the selected tertiary amines into salts used as cationic ingredient of the new preparations is achieved by the usual formation of salts with cosmetically acceptable acids which may be inorganic, such as hydrochloric acid, and phosphoric acid, or organic acids as acetic acid, adipic acid, tartaric acid, malic acid, nitriletriacetic acid, ethylenediamine-tetraacetic acid, citric acid, lactic acid, glycolic acid and mixtures of the above-mentioned acidsv Quite generally speaking, any acid may be used that furnishes with the harmless amine salts that are neither toxic nor irritate the scalp, more especially the salts mentioned specifically below, such as are used in the present invention to establish the desired pH range.

To convert the tertiary amine compounds into quaternary ammonium compoundswhich may likewise and with special advantages be used as cationic ingredient of the new preparationsthey are reacted in known manner with a quaternating agent, for example methyl iodide, dimethyl sulfate, benzyl chloride or with ethylen hlorohydrin or with a polyglycol chloride.

It has further been found that the above-mentioned valuable properties of the new shampoos are particularly evident in those preparations in which the ratio of the cationic ingredient (a) to the non-ionic ingredient (b) ranges from 1:1 to 1:30, preferably from 1:2 to 1:10. More especially at a ratio of (a) (b) of 1:3 it was found that t the new preparations had surprisingly advantageous properties insofar as their lathering power and the stability of the lather, good washing power, gentleness towards the skin and absence of the poissage-effect are concerned.

When the above-mentioned ratios are used, the new preparations have a particularly long shelf-life.

The preparations of the invention should have a moderately acidic to neutral reaction, for example ranging from pH 3.0 to 7.0. The desired pH value may be adjusted with any inorganic or organic acidic compound acceptable for use in cosmetics, for example with acetic acid or phosphoric acid, or with acid phosphates, or adipic, tartaric, malic, nitrilotriacetic, ethylenediamine-tetra:

acetic, citric, lactic or glycolic acid.

Likewise suitable for this purpose are mixtures of inorganic and organic acids, for example mixtures of phosphoric acid and citric acid.

The new shampoos containing the new combinations are obtained by simply mixing and dissolving the ingredients, if desired with further addition of compounds conventionally contained in shampoos, such as perfume, dyestuffs, bleaching agents or thickening agents.

There may be further added fatty acid alkanol-amides, for example coconut oil fatty acid hydroxyethy -amide. The new preparations may be prepared in solid, pasty or liquid form. They are applied in the known hairdressing manner.

Very favourable results were obtained with hair shampoos of the composition set forth above in this application, wherein the weight ratio of cation-active component (l) to nonionic component (2) ranges from 1:1 to 1:100.

Parts in the following examples are parts by weight.

Example 1 (a) The non-ionic polyglycol ethers listed in the following Tables I to V were examined for their lathering power. The results are shown in the tables under Lather volume I.

(b) The cationic compounds listed in the following 6 Tables I to V were examined for their l'at'hering power. The results are shown in the tables under Lather volume II.

(c) Combinations of the cationic and non-ionic compounds shown in Tables I to V were examined for their lathering power. The results are shown in the tables under Lather volume C.

The amounts of the ingredients making up the combinations are shown in the tables under C; I refers to the percentage of the non-ionic share of the total weight of the shampoo solution, and II refers to the cationic share of the total weight of the solution. The remainder of the total weight is accounted for by water and the amount of acid necessary to establish the pH value.

The shampoo solutions listed in the following Tables I, II and V were prepared by dissolving the non-ionic compound and the cationic compound in water with addition of a sufiiciency of citric acid to establish a pH value of 4 to 4.5 of the individual solutions.

The term lather volume in the following Tables I to V refers to the amount of lather in cc. produced by twice washing 10 g. of homogeneously dirtied raw wool, moistened with g. water at C. with 2.7 cc. of the individual shampoo solution in each case. The indices 1 and 2 underneath lather volume in Tables I to V refer to the first and second wash each performed in the method employed for determining the lather volume.
