3,149,042 HAIR PREPARATIONS Lojo Habicht, Hamburg, and Arno Kluge, Bad Soden,

Taunus, Germany, assignors to Colgate-Palmolive Company, New York, N.Y., a corporation of Delaware No Drawing. Filed June 24, 1960, Ser. No. 38,459 Claims priority, application Germany, July 9, 1959, P 23,120 14 Claims. (Cl. 167-87) 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 an aqueous 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 Bari 0.05 570% of a water sglub le dgcjn g agent selected from the group consisting of water-soluble salts of sulfur oxygen acids having from 2 to 3 sulfur atoms, salts of phosphorous acid, and reducing sugars, and 0.05 to of a diamide having the formula wherein X is selected from the group consisting of oxygen and sulfur, and R R R and R are selected from the group consisting of hydrogen, alkyl, alkylol and acyl and mixtures thereof, and n is from 1 to 2, in an aqueous medium.

Suitable diamide compounds having the above formula include u r ea, thiourea, biuret, thiobiuret, dithiobiuret and their water-soluble monoand polyalkyl, -alkylol and -acyl derivatives. In general the alkyl, alkylol and acyl groups may be of saturated or unsaturated nature and may be straight chain or branched having not more than 4 carbon atoms, although in the case of biuret derivatives it is preferred that the chain length of the alkyl, alkylol and acyl groups be limited to not more than 2 carbon atoms. Examples of suitable compounds include, e.g.,

1,3-dimethyl-urea, 1-methyl-3-acetyl-urea, tetramethyl-urea, 1,1-diethyl-urea, l-ethyl-3-propionyl-urea, 1,1-dipropyl-urea, l-propyl-B-butyryl-urea, 1-methyl-1-isobutyl-urea, l-(tert.butyl)-urea,

The reducing agents of the present invention are watersoluble and skin-compatible, i.e. may be applied to the skin in the proportions of the present compositions on a daily schedule without any untoward effect. Preferred for use as reducing agents are the reducing sugars, i.e. sugars which are characterized by containing a fre carbonyl group, the ability to reduce Fehlings solution, and the inability to reduce iodine solutions. Such sugars include, e.g., monosaccharides such as glucose, fructose, a mixture of both such as invert sugar, and galactose, as well as reducing disaccharides such as maltose and lactose. These sugars are especially stable against air oxygen as well as against other components of the hair preparation, particularly perfumes, and may therefore be used at relatively high concentrations, i.e., up to 20%. Moreover, it has been found that use of these sugars is highly beneficial in that they lower substantially both the cloud point and the clear point of the present aqueous compositions.

Also suitable for use as inorganic skin-compatible reducing agents are the water-soluble salts of dithionous ago, thiosulfuric acid, trithionic acid, and phosphorous acid, e.g. sodium dithiom te, sodium thiosulfate, sodium trithionate, and the sodium salt of phosphorous acid.

The instant water-soluble reducing agents are employed in the present hair preparations in an amount from about 0.05 up to 5%, and sometimes up to 20%. In the case of the reducing sugars, the preferred proportion is in the range of 1 to 5%, whereas the inorganic reducing salts desirably are used in an amount within the range of 0.5 to 2% of the final product.

Normally, the diamide is present in an amount from about 0.05 to 10% and preferably from 0.5 to 5% of the hair preparation, and typically the ratio of reducing agent to diamide will be 1:5 to 5:1 and preferably 1:2 to 2:1.

The present aqueous compositions may be prepared in various forms including inter alia, aqueous and aqueousalcoholic solutions, emulsions, pastes, crearnsflotions and the like. They may consist of one or more phases, at least one of which however is aqueous. For instance the hair preparation may consist of 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-in-water type.

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 composition such as hair dyeing 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 from decorative or treating compositions such as hair dressings, hair tonics and the like, in which case the nonvolatile toile t agent for the daily care of the hair is a hair grooming agent, 9 r they may be prepared in the farm of ham cleansing products such as shampoos, in which case the non-volatile toilet agent for the daily care of the hair is a detergent mate i a l. In both hair grooming and hair cleansing compositions however, the nonvolatile toilet agent for the daily care of the hair is normally present in an amount from 0.5 to 65% by weight of the composition.

In the case of hair grooming compositions, examples of agents which facilitate grooming of the hair and help to keep the hair in place include, e.g., castor oil, mineral oil, lower alkoxypolyoxy lower alkylene glycols such as butoxypolyoxy propylene 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 grooming agents which have a molecular weight above about 75 and preferably above 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 about 0.5 to 65% and preferably about 2 to 50% by weight of the composition.

In the case of hair cleansing compositions or shampoos, the non-volatile organic toilet agent for the care of the hair is a cleansing agent such as a water soluble organic detergent. Desirably 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, preferably 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 tallow diglyceride monosulfate; the long chain pure or mixed alkyl 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 higher fatty acid esters of low molecular weight alkylol sulfonic acids, e.g., oleic acid ester of isethionic acid; the sulfated higher fatty acid alkylolamides such as, e.g., ethanolamide sulfates; the higher fatty acid amides of amine 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 substituent containing 8 to 26 carbon atoms. 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 substituent should be 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 the detergents may be used in the form of their alkali salts, e.g., sodium, potassium or lithium salts, as well as in the form of salts of nitrogen containing bases, e.g., ammonium or lower alkylolamine salts such as mono-, diand triethanolamine salts, and mixtures of various 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.

Further suitable organic detergents include nonionic detergents such as the lower alkylene oxide condensation products of hydrophobic compounds, e.g., the ethylene oxide condensation products with higher fatty acids, higher fatty alcohols or alkylated aromatic hydrocarbons, polypropylene glycols having a molecular weight greater than 900, amide and amine condensates such as fatty acid alkylol amides, e.g., N-bis(2-hydroxyethyl)-lauramide, and finally the condensation products of fatty acid chlorides with hydrolyzed natural proteins often referred to as lysalbinic acid derivatives.

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

Shampoos in accordance with the present invention may be prepared in various forms and may consist of one or more phases. The shampoos suitably may be prepared as a clear, homogeneous, single phase liquid such as an aqueous or aqueous-alcoholic composition, or they may contain two or more liquid or mixed liquid and solid phases, as in the case of cream shampoos, lotion shampoos, paste shampoos, and the like. The foregoing detergents desirably comprise at least about 5% and preferably from about 15 to 40% of the instant shampoos, and may be substantially higher in the case of solidscontaining products, e.g. pastes.

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 hair preparation preferably 0.25 to 1.0% may be employed. In a single phase composition containing aqueous alcohol the diamide compounds are more soluble and therefore preferably 0.25 to 2.0% may be employed. In cream type or solid-containing preparations wherein the partly limited solubility of the diamide compounds is not a concentration-lmiting factor, amounts of diamide on the order of up to about 10% may be used.

For example, an aqueous cosmetic composition may comprise from 0.05 to 10% of diamide, from 0.05 to 20% of water soluble reducing agent, from 0.5 to 65% of the non-volatile organic toilet agent, and, as the balance, e.g. 5 to 99.4%, 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 preparation of a clear, homogeneous single phase aqueous shampoo, typically 0.25 to 2% of the instant diamide compounds, 0.25 to 5% of water soluble reducing agent, 5 to 20% water soluble detergent, and 73 to 94.5% water and various adjuvants are used, whereas in a shampoo containing aqueous alcohol wherein the diamide compounds and detergents are each more soluble, more than 2% of the diamide may be used, e.g. up to 5%, in combination with 5 to 40% of the detergent, the balance being aqueous alcohol and other components.

The present hair preparation 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 solid substances which may be deposited on and clog the pores of the scalp. Desirably the instant compositions have a pH of 4 to as they appear most effective in this range. In this connection it is preferred that the reducing agent and diamide in compositions characterized by a pH above 8 (typically such as, for example, soap shampoos) be, respectively, a reducing sugar and biuret or thiobiuret or their alkylor alkylolderivatives in view of the better stability thereof at an elevated pH as compared to urea.

The hair preparations of the invention exhibit unusually 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-otf skin.

The efiiciency of aqueous compositions prepared in accordance with the present invention is favorably influenced by the presence of a water soluble material which reduces the surfaceand/or interfacial-tension 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 and scalp so that soil and oily secretions are more easily displaced and eliminated, thus aiding in the grooming and care of the hair.

Specific hair preparations according to this invention are illustrated by the following examples. All quantities indicated are by weight unless otherwise specified.
