No. 36,754 (Ilaims priority, application Germany, duly 7, 1959, P 23,1tl2 11 Claims. (Cl. l6787) The present invention relates to a cosmetic composition suitable for daily use in the care of the hair. More particularly it relates to hair cleansing and grooming compositions such as hair lotions, tonics, shampoos and the like which may be used in the daily toilet.

in accordance with the present invention a cosmetic composition suitable for daily use in the care of the hair and scalp comprises a substantially non-volatile organic toilet agent for the daily care of the hair and a diamide compound having the formula wherein X is selected from the group consisting of oxygen sulfur, R R R and R are selected from the group consisting of hydrogen alkyl, alkylol and acyl, and R is selected from the group consisting of hydrogen and alkyl, said R R R R and R containing up to two carbon atoms each, and from 40 to 99.45% of a volatile aqueous solvent medium, said composition having a pH of from 4 to and being free of reducing agents. Suitable such compounds include biuret, thiobiuret, dithiobiuret, and their waterand alcohol-soluble monoand polyalkyl, -alkylol and -acyl derivatives wherein the alkyl, alkylol and acyl groups have in general not more than 2 carbon atoms, e.g. l-rnethyl-biuret, S-methylbiuret, l-ethyl-biuret, 1,5-dimethyl-biuret, 1,3,5-trimethylbiuret, l-hydroxymethyl-biuret, 1,5-dihydroxymethyl-biuret, I-acetyl-biuret, 1-forrnyl5-acetyl-biuret, 1,5-dimethyl-l-acetyl-biuret, 1,3,5-trimethyl-l-acetyl-biuret, 3-ethyll-acetyl-biuret, l-methyl-thiobiuret, l-ethyl-thiobiuret, 1 acetyl-thiobiuret, 1 hydroxymethyl-thiobiuret, and l-methyl-dithiobiuret.

The cosmetic compositions of the present invention may be prepared in a wide variety of physical forms. They may be liquids, pastes or solids and may consist of one or more phases. They may, for example, constitute a single aqueous or aqueous-alcoholic phase, or may comprise an aqueous and a separate oily phase as in two layer systems or emulsions of the water-in-oil or oil-inwater types.

The instant compositions and their constituents are skin-compatible, being suitable for periodic use at short, i.e. daily or at the most weekly, intervals, as distinguished from decorative or treating compositions such as hair dye ing or waving compositions which can be used only at much greater intervals. Thus it is contemplated that the present cosmetic compositions may be prepared in the form of daily hair grooming products such as hair 10- tions, hair dressings, hair tonics and the like, or they may be prepared in the form of hair cleansing products such as shampoos, the non-volatile organic toilet agent for daily care of the hair being present in each instance in an amount from 0.5 to 98% by Weight of the composition.

In the case of hair grooming compositions, the nonvolatile organic toilet agent for the daily care of the hair stituent containing 8 to 26 carbon atoms.

is an agent which facilitates grooming of the hair and helps to keep the hair in place. Such hair groonnng agents include, e.g., castor oil, mineral o1l, lower alkoxypolyoxy lower alkylene glycols such as butoxypolyoxypropylene glycol, higher molecular weight copolymers of random mixtures of ethylene oxide and propylene oxide, esters of fatty acids such as isopropylmyristate or the coconut oil fatty acid ester of polyethylene glycol having an average molecular Weight of about 400, polyhydric alcohols such as glycerol and propylene glycol, gums such as gum tragacanth, lacquers such as shellac, and the like. It is preferred to employ those substantially non-volatile organic hair grooming agents which have a molecular weight greater than about and preferably greater than about 200 and which contain an alcoholic hydroxyl group such as the aforementioned glycols, polyhydric alcohols, polymerized alkylene oxides, and castor oil. The foregoing organic hair grooming materials desirably are employed in the instant hair grooming preparations in an amount from 0.5 to 50% and higher depending on the nature of the respective compound and its compatibility in the desired system.

In the case of hair cleansing compositions or shampoos, the non-volatile organic toilet agent for the daily care of the hair is a cleansing agent such as a water-soluble organic detergent. Preferably this detergent is an anionic sulfate or sulfonate, i.e. a sulfated or sulfonated compound having a hydrophobic substituent containing 8 to 26 carbon atoms, desirably from 12 to 18 carbon atoms, per molecule.

Detergents of this preferred type which may be suitably employed include the sulfuric acid esters of polyhydric alcohols incompletely esterified with higher fatty acids, e.g., coconut oil monoglyceride monosulfate and fallow diglyceride monosulfate; the long chain'pure or mixed'allryl sulfates such as lauryl sulfate, cetyl sulfate, and higher fatty alcohol sulfates derived from coconut oil; the hydroxy sulfonated higher fatty acid esters such as, e.g., higher fatty acid esters of 2,3-dihydroxypropane sulfonic acid; the lugher fatty acid esters of low molecular weight alkyiolsulfonic acids, e.g., oleic acid ester of isethionic acid; the sulfated higher fatty acid alkylolamides such as, e.g., CthSIiOIZLrldC sulfates; the higher fatty acid amides of amino alkyl sulfonic acids, e.g., the lauric amide of taurine, and the like.

Other anionic synthetic detergents which may be employed in shampoos are the sulfonic acid salts of alkylated aromatic hydrocarbon compounds having an alkyl sub The aromatic portion of the molecule may be monoor polynuclear, e.g., benzene, toluene, Xylene, naphthalene, phenanthrene, anthracene, etc., and may contain other substituents such as hydroxyl groups or short chain alkyl groups such as, e.g., in phenol, cresol, phenol ethers, toluene, Xylene, etc. The long chain alkyl substituent of the alkylated aromatic molecule preferably is saturated and may be straight chain or branched. Representative long chain alkyl groups include the dodecyl, hexyl, octyl, nonyl, and decyl groups as well as mixed alkyls derived from fatty materials, cracked parafiins or polymers of lower mono olefins, etc. In general, the alkylated aromatic detergents employed will be a mixture of compounds having alkyl substituents of varying chain length since the chain length is dependent upon the sharpness of the fractionation of the aliphatic hydrocarbon used for the alkylation. The average chain length of the alkyl substituents shouldbe in general from 9 to 15 carbon atoms and preferably between 12 and 14 carbon atoms.

These various anionic detergents are employed in shampoos prepared in accordance with the present invention in the form of their water-soluble salts. Thus, detergents may be used in the form of their alkali salts, e.g.,

as sodium, potassium or lithium salts, or as ammonium salts, as well as in the form of salts of nitrogen containing bases, e.g., as salts of low molecular alkylolamines such as mono-, diand triethanolamine, and as mixtures of various of these salts.

Other anionic detergents which may also be employed include water-soluble alkyl phosphates, sulfated ethylene oxide condensates of hydrophobic materials such as higher fatty acids, fatty alcohols, alkyl aromatic hydrocarbons and the like, sulfonated oils, soaps such as sodium, potassium and triethanolamine soaps of higher fatty acids containing from 12 to 18 carbon atoms as well as mixtures of soaps being especially useful such as sodium laurate, sodium palmitate, sodium oleate and the potassium and/or triethanolamine soaps of coconut oil, palm oil, and tallow fatty acids.

lauroyl pyridinium bromide, cetyl trimethyl ammonium chloride or cetyl pyridinium chloride may also be used alone or'in combination with other compatible detergents. Suitable salts of cationic detergents are the chloride, bromide, acetate and sulfate. V

Suitable detergents are furthermore the amphoteric detergents such as salts of the N-alkyl compounds of betaamino propionic acid wherein the alkyl group is derived from a fatty acid fatty acids.

Shampoos in accordance with the present invention may be prepared in any convenient physical form and may consist of one or more phases. Thus such a shampoo such as the mixture of coconut oil 'may be a solid product such as a bar or a powder, or a clear, homogeneous single phase liquid such as an aqueous or aqueous-alcoholic composition, or it may contain two or more liquid or mixed liquid and solid phases, as in ably comprise 'at least and prferably from to 40% "of the instant shampoos when they are prepared in a liquid or paste formQand from 15 to 98% when the shampoo is prepared in the form of a solid'composition;

The diamide compounds of the present invention constitute a minor proportion, on the order of 0.05 to 10% of the instant hair preparations, the most suitable amount depending on the characteristics desired; Thus, in a clear, homogeneous, single phase,.aqueous type of hair preparation preferably an amount on the order of 0.25 to 'the case of cream-shampoos, lotion-shampoos, pasteshampoos, and the like. The foregoing detergents desir- 1.0% of the composition in employed. In a single phase 1 For example, an'aqueous cosmetic composition may comprise from 0.05 to 10% of diamide, from 0.5 to 50% of the non-volatile organic toilet agent, and as the balance,

e. g.14099.45%, a volatile aqueous solvent medium such as water or mixtures of water and a lower monohydric alcohol such as ethanol or isopropyl alcohol. In the reparation of a clear, homogeneous single phase aqueous shampoo, preferably 0.5 to 2% of one of the instant diamide compounds, 5 to 20% water soluble detergent, and 7894.5% water and other components are used, Whereas in a shampoo containing aqueous alcohol wherein said diamide compounds and detergents are each more soluble, more than 2% of the diamide may be used in combination with 5 to 40% of the detergent, the balance being aqueous alcohol and other components. In solid, powder or cream shampoos amounts of 0.05 up to 10% of diamide are possible in combination with 15 to 98% of the detergent and'a balance of water and/ or other components.

The instant hair preparations may also contain as adjuvant materials various substances such as vitamins, hormones, cholesterol, lanolin, bactericides, plant extracts, buffers, and the like in compatible proportions, although the preparations should be free of substantial quantities of water insoluble sohd substanceswhich may be deposited on and clog the pores of the scalp. Desirably the present compositions have a pH of 4 to 10 as they appear to be most effective in this range.

The hair preparations of the invention exhibit unusua ly excellent hair grooming properties. They render the hair soft and manageable, impart a high gloss and luster, and are particularly effective in controlling or preventing the formation of dry flaky scales of sloughed-oif skin.

The efiiciency of aqueous compositions prepared in accordance with the present invention is favorably infiuenced by the presence of a water soluble material which reduces the surfaceand/or interfacialatension of water (e.g. alcohol in alcoholic hair tonics, soaps or synthetic detergents in shampoos, emulsifiers in hair dressings). The presence of these surface active materials is believed to reduce the interfacial tension between the aqueous phase containing the instant water soluble diamides and the hair v and scalp so that soil and oily secretions are more easily temperature or elevated temperature in the amount of water, alcohol or aqueous alcohol required for the respective hair preparation. Thereafter, the toilet agent for the daily care of the hair may be added in the usual way, i.e.

in the case of hair tonics, liquid shampoos or hair rinses the hair grooming agent may be added to the liquid containing the diamide of the invention, and in the case of hair creams of the oil-in-water or water-in-oil type, the

liquid containing the diamide may be heated to 50-70 C. and emulsified with the molten fats, mineral oils orlike hair grooming agents, the emulsion, if necessary, being homogenized thereafter.

Cream shampoos formulated in accordance with the present invention may be prepared by mixing an aqueous detergent paste with an appropriate diamide compound and any other desired components with stirring at an elevated temperature (4060 C.)..

Powder shampoos may be made by homogeneously mixing the desired components in a mixer.
