This invention has as its object the use of cationic polymers as cosmetic agents, cosmetic compositions containing these polymers, and a process of treating hair, skin or nails with said polymers.

It has already been proposed to use various cationic polymers as pesticides, flocculating agents, etc. It has also been proposed to use certain cationic polymers as cosmetic agents; see, for example, French Pat. No. 75.15162.

It has now been discovered that the use of certain particular cationic polymers offers advantages in comparison with cationic polymers previously used. Some of these advantages will be disclosed below in the present specification.

and when A.sub.3 represents --E--OD).sub.z OE--

D represents a group --(CH.sub.2).sub.2 --, --CH.sub.2 --CH(CH.sub.3)-- or --(CH.sub.2).sub.2 --,

and z can vary particularly from 2 to 18.

It should be noted that the invention extends to the cosmetic use of formula (I) polymers wherein the groups A.sub.1, X, A.sub.2, A.sub.3, R.sub.1, R.sub.2, R.sub.3 and/or R.sub.4 have several different values in the same polymer I.

In addition, the formula I polymers can be copolymers further containing formula I' groups: ##STR7## wherein A'.sub.1 is a saturated or unsaturated linear or branched hydrocarbon, particularly a substituted or unsubstituted alkylene or arylene group having up to 20 carbon atoms.

The formula (I) polymers can be prepared by a standard process consisting in submitting to a polycondensation reaction a ditertiary diamine of the formula: ##STR8## wherein:

A.sub.1, X, A.sub.2, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are defined above, with a compound of the formula Z--A.sub.3 --A,

Z and A.sub.3 being defined as above.

Formula (I) polymers can also be prepared by causing a ditertiary diamine of the formula ##STR9## to react on a derivative of the formula

Further, to obtain copolymers containing formula I' groups, a part of the ditertiary diamine mentioned above is replaced by a tertiary diamine of the type ##STR10## or a part of the compound Z--A.sub.3 --Z or Z--A.sub.1 XA.sub.2 --Z, for example, by the compound Z--A'.sub.1 --Z--.

The polycondensation reaction is performed, for example, in a solvent or mixture of solvents favoring quaternization reactions, such as water, dimethylformamide, acetonitrile, lower alcohols, particularly lower alkanols such as methanols, etc.

The reaction temperature can vary between 10.degree. and 150.degree. C. and preferably between 20.degree. and 100.degree. C.

The reaction time depends on the nature of the solvent, starting reagents and degree of polymerization desired.

Generally, the starting reagents are made to react in equimolecular amounts, but it is possible to use either diamine or dihalide in slight excess, this excess being less than 20% in moles.

The resulting polycondensate is optionally isolated at the end of the reaction either by filtration or by concentration of the reaction mixture.

It is possible to regulate the average length of the chains by adding, at the beginning or during the reaction, a slight amount (1 to 15% in moles in relation to one of the reagents) of a monofunctional reagent such as a tertiary amine or a monohalide. In this case, at least a part of the end groups of the resulting polymer I consists of either the tertiary amine groups used or the hydrocarbon group of the monohalide.

Some formula (I) polymers are known particularly from French Pat. No. 78.17373 and from British Pat. No. 1,288,006.

The invention extends to the cosmetic use of formula (I) polymers having such end groups.

Instead of the starting reagent it is also possible to use either a mixture of ditertiary diamines or a mixture of dihalides or again a mixture of ditertiary amines and a mixture of dihalides provided that the ratio of the total molar amounts of diamines and dihalides is close to 1.

The starting products of formula A.sub.3 (Z).sub.2 can be prepared by standard methods like those described, for example, in French patent application No 76.02948; by Perry-Hibbert, Canad. J. Res. (B), 14 (1936), 82; Fordyce and Lowell H., J. Am. Chem. Soc., 61 (1939), 190; Johansson, Eur. J. Biochem., 33, 379 (1973).

The starting ditertiary diamines can be prepared by standard processes like those described, for example, in French Pat. No. 75.15162; U.S. Pat. No. 4,110,263.

Further, in case, for example, the starting diamine is of the type: ##STR11## it is possible to obtain a crosslinked polymer either by using an excess of reagent A.sub.3 (Z).sub.2 or after having made said starting amine react with a fairly equimolecular amount of reagent A.sub.3 (Z).sub.2, by making the resulting polymer react with another bifunctional derivative. Thus, it is possible to obtain any variety of polymers (I) having variable degrees of crosslinking.

The invention particularly has for its object the use of formula I polymers described below in the experimental part.

Although the invention is not limited to use of polymer I with a degree of polymerization varying in a particular field, it can be pointed out that the formula (I) polymers that can be used according to the invention have a molecular weight generally between 1,000 and 50,000.

They are generally soluble in at least one of the three solvents consisting of water, ethanol or a water-ethanol mixture.

By evaporation of their solution, it is possible to obtain films that particularly exhibit a good affinity for hair.

In contrast with certain cation agents, they are generally compatible with nonionic derivatives used in a standard way in the preparation of compositions in gel form.

As indicated above, the formula (I) polymers exhibit attractive cosmetic properties that make it possible to use them in preparing cosmetic compositions.

This invention also has for its object cosmetic compositions characterized by the fact that they comprise at least a formula (I) polymer. These cosmetic compositions generally comprise at least an adjuvant usually used in cosmetic compositions.

The cosmetic compositions of the invention comprise formula (I) polymers either as main active ingredient or as additive.

These cosmetic compositions can be in the form of aqueous, alcohol or dilute alcohol solutions (the alcohol particularly being a lower alkanol such as ethanol or isopropanol) or in the form of emulsions, creams, lotions, powders or gels, and can be packaged as aerosols containing a propellant such as, for example, nitrogen, nitrogen protoxide or fluorocarbons of the "Freon" type.

The adjuvants generally present in the cosmetic compositions of the invention are, for example, perfumes, dyes, preservatives, sequestering agents, thickeners, filters, peptizers, emulsifiers, or again cosmetic resins usually used in hair compositions.

It should be noted that the cosmetic compositions according to the invention are both ready-to-use compositions and concentrates that have to be diluted before use. The cosmetic compositions of the invention are therefore not limited to a particular field of concentration of formula (I) polymer.

Generally, in the cosmetic compositions of the invention, the concentration of formula (I) polymers is between 0.01 and 15% by weight, particularly between 0.1 and 10% and preferably between 0.25 and 5%.

The formula (I) polymers particularly exhibit attractive cosmetic properties when they are applied to hair.

Thus, when they are applied to the hair either alone or with other active substances during a treatment such as a shampoo, dyeing, setting, brushing, permanents, etc., they notably improve the qualities of the hair.

For example, they enhance the treatment and facilitate untangling of wet hair. Even in a strong concentration, they do not give wet hair a gluey touch.

In contrast with the usual cationic agents, they do not make dry hair heavy and therefore facilitate bouffants. They give dry hair lively qualities and a glossy appearance. Untangling of dry hair is facilitated.

They effectively contribute to eliminating the defects of hair sensitized by treatments such as bleachings, permanents or dyeings. It is indeed known that sensitized hair is often dry, dull and rough and difficult to untangle and set.

In particular they offer a great advantage when they are used as pre- or post-treatment agents, particularly in the form of rinse compositions (rinses, creams or gels) applied before or after bleaching, dyeing, a permanent or shampoo.

The cosmetic compositions for hair according to the invention generally comprise at least an adjuvant usually used in cosmetic hair compositions to be able to offer them in the form of aqueous, alcohol or dilute alcohol solutions, in the form of emulsions (particularly creams), gels or powder.

The formula (I) polymers can be present in the cosmetic hair composition, either as an additive or as a main active ingredient in setting lotions, treating compositions, hairdo lotions, creams or gels, or again as an additive in shampoo, setting, setting, permament, dye compositions, restructuring lotions, seborrhea treating lotions, hair lacquers.

The cosmetic hair compositions according to the invention therefore particularly comprise:

(a) treating (or hairdo) compositions characterized in that they comprise as an active ingredient at least a formula (I) polymer.

These treating compositions can be lotions, creams or gels.

The content of these treating compositions in formula (I) polymer generally varies from 0.1 to 10% by weight, particularly from 0.25 to 5%.

The lotions are aqueous or dilute alcohol solutions of formula (I) polymers.

The pH of these lotions is close to neutrality and can vary, for example, from 5 to 8. If necessary, the pH can be brought to the desired value by adding either an acid such as citric acid or a base, particularly an alkanolamine such as monoethanolamine or triethanolamine. Generally, these lotions contain a perfume and/or a dye intended to color said lotions and/or a preservative.

To treat hair with such a lotion, said lotion is applied to wet hair, allowed to act for 3 to 15 minutes, then the hair is rinsed.

If desired, a standard setting can then be done.

The treating creams are made with a support formulated with a base of soaps or fatty alcohols in the presence of emulsifiers. The soaps can be made up from neutral or synthetic fatty acids with C.sub.12 -C.sub.20 (such as lauric acid, myristic acid, palmitic acid, oleic acid, ricinoleic acid, stearic acid, isostearic acid and their mixtures) in concentrations between 10 and 30% and alkalizing agents (such as soda, potash, ammonia, monoethanolamine, triethanolamine and their mixtures).

Besides polymer I and soap, these creams can contain adjuvants such as fatty amides and fatty alcohols.

Of the fatty acids the following compounds in particular can be used: mono or di-ethanolamide of acids derived from copra, lauric acid, oleic acid or stearic acid in concentrations between 0 and 15%.

Of the fatty alcohols there can be used in particular lauric, oleic, myristic, cetyl, stearic, isostearic alcohols in concentrations between 0 and 25%.

The emulsifiers can, for example, be either nonionic emulsifiers such as oxyethylenated or polyglycerolated fatty alcohols as for example oleic alcohol polyoxyethylenated with 10 to 30 moles of ethylene oxide, stearyl alcohol with 10-15 or 20 moles of ethylene oxide, oleic alcohol polyglycerolated with 4 moles of glycerol and synthetic fatty alcohols with C.sub.9 -C.sub.15 polyoxyethylenated with 5 to 10 moles of ethylene oxide, these nonionic emulsifiers being present at a rate of 1 to 25% by weight, or ionic emulsifiers such as alkyl sulfates oxyethylenated or not such as sodium lauryl sulfate, ammonium lauryl sulfate, sodium cetyl stearyl sulfate, triethanolamine cetyl stearyl sulfate, monoethanolamine lauryl sulfate, sodium lauryl ether sulfate oxyethylenated (with 2.2 moles of ethylene oxide, for example) and monoethanolamine lauryl ether sulfate oxyethylenated (with 2.2 moles of ethylene oxide, for example), these latter emulsifiers being present in concentrations between 0.5 and 15% by weight.

The treating gels contain thickeners such as sodium alginate or gum arabic or cellulose derivatives in the presence or not of solvents. It is also possible to obtain a thickening of the lotions by mixing polyethyleneglycols and polyethyleneglycol stearates or distearates, or, by mixing phosphoric esters and amides, or again by mixing surfactants and solvents in an aqueous medium.

The concentration of thickener can vary from 0.5 to 30% and preferably from 0.5 to 15% by weight.

The solvents used can be lower aliphatic alcohols, glycols and their ethers. The concentration of these solvents can vary between 2 and 20%.

As indicated above, the treating compositions defined above can be used particularly before or after bleaching, dyeing, a permanent or shampoo. After an application period of 3 to 30 minutes, during which the composition is allowed to act, the hair is rinsed.

These compositions in the form of shampoos can also contain various adjuvants such as, for example, perfumes, dyes, preservatives, thickeners, foam stabilizers, softeners.

In these shampoos the detergent concentration is generally between 3 and 50% by weight, and the formula (I) polymer concentration particularly between 0.1 and 5% and in particular between 0.25 and 5%.

(c) setting lotions or blow-dry lotions, particularly for sensitized hair, characterized by the fact that they comprise at least a formula (I) polymer, in aqueous, alcohol or dilute alcohol solution.

They can further contain at least another cosmetic resin. The cosmetic resins that can be used in such lotions are very varied. They are known and described in works on cosmetology. They are particularly homopolymers or copolymers such as, for example, polyvinylpyrrolidone, polyvinylpyrrolidone and vinyl acetate copolymers, crotonic acid and vinyl acetate copolymers, etc.

The concentration of formula (I) polymers in these setting lotions varies particularly between 0.1 and 5%, for example, between 0.25 and 5%, and the concentration of cosmetic resin varies approximately in the same proportions.

The pH of these setting lotions generally varies between 3 and 9 and preferably between 4.5 and 7.5.

(d) hair dye compositions characterized by the fact that they comprise at least a formula (I) polymer, at least a dye agent for hair and a support.

The support is selected to constitute either a cream or a gel.

The concentration of formula (I) polymers in these dye compositions varies preferably between 0.5 and 15%.

In case of an oxidation dye, the dye composition is packaged in two parts, but in a package comprising the mode of use, the second part being hydrogen peroxide. The two parts are mixed at the time of use.

When the dye composititons are creams, they comprise, beside polymer I, various ingredients permitting the presentation in the form of creams like the treatment creams defined above, to which are added an alkalizing agent and dyes.

The pH of these compositions is generally between 8 and 11 and can be regulated by addition of a suitable alkalizing agent in the dye support for example by addition of ammonia, monoethanolamine, diethanolamine or triethanolamine.

The dyes belong to the class of oxidation dyes to which can be added direct dyes such as azoics, anthraquinones, nitro derivatives of the benzene series, indamines, indoanilines, indophenols, or other oxidative dyes such as leukoderivatives of these compounds.

Said "oxidation dyes" are aromatic compounds of the diamine, aminophenol or phenol type. These aromatic compounds are dye precursors which are transformed into dye compounds by condensation in the presence of a great excess of oxidant, generally hydrogen peroxide. In oxidation dyes there are distinguished, on the one hand, "bases" which are diamines or aminophenols (ortho or para derivatives) and, on the other hand, "modifiers" which are m-diamines, m-aminophenols or polyphenols.

When the dye compositions are gelable liquids, they contain, besides formula (I) polymer and dyes or dye precursors, either polyoxyethylenated or polyglycerolated nonionic derivatives, and solvents, or soaps of liquid fatty acids such as those of oleic or isostearic acid, and solvents. The soaps are soda, potash, ammonium or mono-, di- or tri-ethanolamine soaps.

(e) hair lacquers characterized by the fact that they comprise an alcohol or dilute alcohol solution of a usual cosmetic resin for lacquers and at least a formula (I) polymer, this solution being possibly placed in an aerosol container and mixed with a propellant.

Preferably, the bleaching compositions are supports in the form of creams or gelable liquids like those described above in regard to dye compositions. These supports are diluted at the time of use with a solution of hydrogen peroxide and/or peroxides and/or persalts.

They generally contain an alkalizing agent such as ammonia.

The bleaching compositions are applied according to standard techniques.

(h) permanent compositions

It is known that the standard technique for achieving permanent deformation of hair consists, in a first stage, of making openings in the S--S bonds of the hair keratin with a composition containing a reducing agent, then, after having preferably rinsed the hair, of reconstituting in a second stage said S--S bonds by applying an oxidizing composition to the hair subjected to this reduction to give the hair the desired shape.

The formulation of said reducing and oxidizing compositions is known and described in works on cosmetology, particularly by E. Sidi and C. Zviak, "Problemes Capillaires," Paris, 1966 (Gauthier-Villard).

The permanent compositions of this invention are particularly reducing compositions for the first stage of the permanent deformation operation.

The compositions contain, besides the reducing agent, adjuvants making it possible to offer them in the forms of lotions or in the form of powder to be diluted in a liquid support.

The reducing agent is most often a mercaptan such as, for example, thioglycerol or again thioglycolic acid or its derivatives.

The concentration of the reducing agent is the concentration necessary to obtain the reduction of a sufficient number of S--S bonds. These concentrations have been studied and described in works on cosmetology. For example, for thioglycolic acid the concentration is generally on the order of 1 to 11% approximately.

The pH of these compositions for the first stage of a permanent generally varies from 7 to 10.

The compositions for the second stage of a permanent contain an oxidant capable of reconstituting the reduced S--S bonds.

The permament compositions generally contain from 0.1 to 10% by weight of formula (I) polymer and particularly from 0.25 to 5%.

These lotions for the first stage of the permanent are most often aqueous solutions that can contain, in addition, pH modifiers, auxiliary reducing agents such as sulfites, solvents such as ethanol or isopropanol, surfactants, perfumes and/or dyes.

The formula (I) polymers are compatible with the ingredients and adjuvants used in permanent compositions.

The formula (I) polymers also offer attractive cosmetic properties when they are applied to the skin.

Particularly, they give the skin a softness that is noticeable to the touch.

They further offer the advantage of being compatible with the ingredients used to making skin cosmetic compositions.

Further, they generally comprise at least an active ingredient or adjuvant usually used in cosmetic compositions for the skin.

The cosmetic compositions for the skin according to the invention are, for example, in the forms of creams, lotions, emulsions, gels or aqueous, alcohol or dilute alcohol solutions.

The concentration of the formula (I) polymer in these compositions for the skin generally varies between 0.1 and 10% by weight and particularly from 0.25 to 5%.

The adjuvants generally present in these cosmetic compositions are, for example, perfumes, dyes, preservatives, thickeners, sequestering agents, emulsifiers, etc.

These skin compositions particularly constitute treating creams or lotions for the hands or face, antisolar creams, colored creams, cleansing creams, bath foam liquids, aftershave lotions, toilet waters, shaving foams, makeup sticks, colored or uncolored sticks particularly for lips, for makeup or for body hygiene, or again deodorant compositions.

Generally, the composition is allowed to act for 5 to 45 minutes and preferably for 15 to 30 minutes.

The amounts of dye or bleaching composition applied to the hair are generally between 10 and 100 g approximately.

According to another embodiment of the cosmetic treatment process of this application, the invention also has for its object a process of permanent deformation of the hair, characterized by the fact that a sufficient amount of a reducing composition as defined above is applied to the hair, it is allowed to act for about 5 to 20 minutes, the hair is rinsed, a sufficient amount of oxidizing composition to reform the S--S bonds of the hair keratin is applied to the hair that has been thus reduced.

The oxidizing agent is generally hydrogen peroxide or a persalt.

Generally, the hair is subjected to an extension realized particularly by putting up in curlers preferably done before application of the reducing composition.

After application of the oxidizing composition for a sufficient period, the extension of the hair is eliminated, then rinsed. Then setting can be done.

According to another embodiment, the cosmetic treatment process of this application is characterized by the fact that there is applied to the hair, particularly before or after dyeing, bleaching, a permanent or a shampoo, a treating composition as defined above, which is allowed to act for about 3 to 15 minutes, then the hair is rinsed.
