Abstract

Cosmetic compositions for the hair and skin are described which are characterized in that they contain a polymer which comprises recurring units having the general formula ##STR1## in which: k is 0 or 1, and l=1 if k=0, or l=0 if k=1,p=0 or 1 and the radicals R.sub.1 to R.sub.5 represent various specified organic radicals.

Description

The present invention relates to polymers which contain amine groups and comprise units having a cyclic structure, cosmetic compositions containing them and to their use for the care of the hair and the skin.

For some years, it has been proposed to use, for the care of the hair and of the skin, certain polymers which contain amine groups which are either tertiary or quaternary i.e. ammonium groups.

It was in fact found that these polymers had a certain affinity for the keratin of the hair and of the skin and hence made it possible to avoid sensations of dryness and roughness of the hair and of the skin. However, it was also found that these polymers exhibited a degree of incompatibility in some cosmetic compositions, which therefore considerably limited their use.

Furthermore, it was found that the affinity of these polymers was insufficiently durable and hence it was necessary to repeat the applications very frequently in order to impart to the skin and to the hair a natural appearance which is visually pleasing and pleasant to the touch.

It has now been discovered, according to the present invention, that by using a new class of polymers which contain amine groups and comprise units having a cyclic structure, it is possible, on the one hand, to obtain a large variety of formulations without encountering the disadvantages found with the previous polymers and, on the other hand, to achieve a durable effect in view of the greater affinity of the polymers used, according to the invention, towards the keratin of the hair and of the skin.

This invention provides, a cosmetic composition for the care of the hair and of the skin, which contains, in a suitable cosmetic vehicle, at least one polymer which comprises units having a cyclic structure corresponding to the following formulae: ##STR2## in which: k is 0 or 1, and l=1 if k=0, or l=0 if k=1,

According to a third preferred embodiment of the invention the polymers are copolymers which can be represented by the following general formula: ##STR18## in which: R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, Ac, l, k, p and A have the same meanings as above,

The polymers which can be used according to this invention exhibit the peculiarity of being soluble both in water and in alcohols, especially ethanol and isopropanol.

These polymers usually have a molecular weight of 2,000 to 500,000 and preferably 4,000 to 75,000.

The units (Ia) of the polymers can be derived, by cyclopolymerisation, from a salified diallylamine having the following formula: ##STR20## in which: R.sub.1, R.sub.2 and R.sub.3 have the same meanings as above and

In fact, during polymerisation the compounds of the formulae (XIII) and (XIV) cyclise to give the cyclic units (Ia) and (Ib) respectively, which possess either five or six members in the cyclic structure.

Furthermore, if the radical R.sub.5 above represents a radical which carries a polymerisable double bond, the latter can also participate in the cyclisation and in that case units having a bicyclic structure are obtained, as is the case, for example, if the radical R.sub.5 represents an allyl radical.

Amongst the diallylamines of the formula (XIII) which give the units (Ia), there may in particular be mentioned the hydrochlorides, hydrobromides, hydroiodides, nitrates, acetates, butyrates and lactates of N-trichloroacetyl-diallylamine, N-chloroacetyl-diallylamine, N-acetonitrile-diallylamine, N-acetyl-diallylamine, N-propionitrile-diallylamine, N-propionyl-diallylamine and N-benzenesulphonyl-diallylamine, N-ethyl acetate diallylamine, N-methyl acetate diallylamine and the hydrochloride, hydrobromide, nitrate, acetate, butyrate and lactate of diallylmelamine.

Amongst the unsaturated monomers which give the units M.sub.1 of the copolymers of the formula (III) there may in particular be mentioned:

(i) Amongst the monomers of the formula (IV): the N-methyl-diallylamine, N-ethyl-diallylamine, N-butyl-diallylamine, N-octyl-diallylamine and N-dodecyl-diallylamine hydrochlorides, hydrobromides, hydroiodides, acetates, butyrates and lactates.

It will, of course, be understood in formulae (II), (III) and (IX), the units (Ia) and (Ib) and M units are not necessarily in blocks; generally the polymers are random copolymers, x, y, z, x', y', and z' merely representing the molar proportion of the units in question in the polymer.

The copolymers (and homopolymers), can be obtained by copolymerisation in emulsion or in solution in water or an organic liquid such as ethanol, methanol, benzene, toluene or xylene.

Conventional polymerisation catalyst can be used, for example hydrogen peroxide, benzoyl peroxide or azo-bis-isobutyronitrile, but preferably t-butyl peroxypivalate or t-butyl hydroperoxide.

The polymerisation reaction can also be initiated by irradiation or by oxidation-reduction systems such as the hydro peroxide/ferrous chloride or ammonium persulphate/ferrous chloride systems.

The polymerisation is in general carried out at a temperature of 30.degree. to 150.degree. C. and preferably 60.degree. to 90.degree. C.

If it is desired to obtain polymers in which the units (Ia) are in the form of free amines, the polymers obtained in a salified form can be treated with a base such as sodium hydroxide, at ambient temperature.

The cosmetic compositions according to the invention, containing the specified polymers can be in various forms.

The cosmetic compositions according to the invention can contain the polymers either as the principal active ingredient or as an additive i.e. additional ingredient.

Furthermore, the compositions in general contain at least one adjuvant usually employed in cosmetic compositions.

The cosmetic compositions can be in the form of, for example, aqueous, alcoholic or aqueous-alcoholic solutions (the alcohol being, in particular, a lower alkanol such as ethanol or isopropanol), or in the form of creams, gels or emulsions, or in the form of aerosols which contain a propellant.

The adjuvants generally present in the cosmetic compositions according to the invention may be, for example, perfumes, dyestuffs, preservatives, sequestering agents, or thickeners.

It should be noted that the cosmetic compositions according to the invention are either ready-to-use compositions or concentrates which can be diluted before use.

The cosmetic compositions according to the invention are thus not limited to a particular polymer concentration range. In general, the polymer concentration is from 0.01 to 15% by weight and preferably from 0.1 to 10% by weight.

If the specified polymers are applied to the head of hair either by themselves or together with other active substances when carrying out a treatment such as a shampoo, a dyeing operation or a wave-set, they significantly improve the characteristics of the hair and in particular restore its suppleness and an attractive sheen.

Furthermore, they assist the treatment and facilitate the combing-out of the wet hair. In contrast to the previous polymers, they do not make the dry hair heavy and hence make it easy to produce bulky hairstyles. Furthermore, they make an efficient contribution to eliminating the shortcomings of hair which has been sensitised by chemical treatments or deteriorated by the atmosphere, by exposure to the sun or by bathing in the sea.

The polymers used in the compositions according to the invention are of particular value when used as pre-treatment agents, especially with an anionic and/or non-ionic shampoo, or prior to an oxidation dyeing treatment which is itself followed by an anionic and/or non-ionic shampoo.

After such treatment, the hair is particularly easy to comb out and is very soft to the touch.

The polymers can also be used as pre-treatment agents in other hair treatment operations, for example in permanent waving.

The cosmetic compositions for the hair are suitably in the form of aqueous, alcoholic or aqueous-alcholic solutions (the alcohol preferably being either ethanol or isopropanol) or in the form of creams, gels or emulsions, or in the form of sprays. In this latter case, the compositions are packaged in an aerosol container which contains a propellant such as nitrogen, nitrous oxide, carbon dioxide or a fluorochlorohydrocarbon such as those known by the name "Freon", or mixtures of such propellants.

The adjuvants generally present in the cosmetic compositions for hair according to the invention, include perfumes, dyestuffs, preservatives, sequestering agents, thickeners and emulsifiers as well as hair resins.

The cosmetic compositions for hair, according to the invention, thus include, in particular:

(a) Treatment compositions which contain at least one polymer, in aqueous or aqueous-alcoholic solution, as the active ingredient.

The polymer content is generally 0.01 to 15% by weight and preferably 0.1 to 8% by weight.

The pH of these lotions in near the neutral point and can, for example, be from 6 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, especially an alkanolamine such as monoethanolamine or triethanolamine.

In order to treat the hair with such a lotion, the lotion is applied to the wetted hair and is allowed to act for, say, 3 to 15 minutes, and the hair is then rinsed.

The hair can then be wave-set if desired.

(b) Shampoos which contain at least one polymer and a cationic, non-ionic or anionic detergent.

Suitable cationic detergents include long-chain quaternary ammonium compounds, esters of fatty acids and aminoalcohols, and polyether-amines.

Suitable non-ionic detergents include esters of polyols and of sugars, condensation products of ethylene oxide with fatty compounds, with long-chain alkylphenols, with long-chain mercaptans or with long-chain amides, and polyethers of polyhydroxylic fatty alcohols.

Suitable anionic detergents include the alkali metal salts, ammonium salts, amine salts or aminoalcohol salts of fatty acids such as oleic acid, ricinoleic acid, copra oil acids or hydrogenated copra oil acids, the alkali metal salts, ammonium salts or aminoalcohol salts of fatty alcohol-sulphates, especially of C.sub.12 -C.sub.14 fatty alcohols and of C.sub.16 fatty alcohols, the alkali metal salts, magnesium salts, ammonium salts or aminoalcohol salts of oxyethylenenated fatty alcohol-sulphates, the condensation products of fatty acids with isethionates, taurine, methyltaurine and sarcosine, the alkylbenzenesulphonates, especially with C.sub.12 -alkyl, the alkylaryl-polyethersulphates and the monoglyceride-sulphates.

All these detergents, as well as numerous others which can be used, are well known and are described in the literature.

These compositions in the form of shampoos can also contain various adjuvants such as perfumes, dyestuffs, preservatives, thickeners, foam stabilisers, softeners, or one or more cosmetic resins.

In these shampoos, the detergent concentration is generally from 5 to 50% by weight and the concentration of polymer of the formula (I) is generally from 0.01 to 15%, and preferably from 0.1 to 5% by weight.

(c) Wavesetting lotions, especially for sensitised hair, characterised in that they contain at least one polymer as defined above, in aqueous, alcoholic or aqueous-alcoholic solution.

These compositions in the form of wavesetting lotions can furthermore contain another cosmetic resin.

The concentration of the specified polymer in these wavesetting lotions is generally from 0.1 to 5%, and preferably 0.2 to 3%, by weight.

The pH of these wavesetting lotions is generally from 3 to 9 and preferably from 4.5 to 7.5.

(d) Hair dyeing compositions, characterised in that they contain at least one polymer, a colorant and a vehicle. The vehicle preferably consists of a cream.

The concentration of polymer is these dyeing compositions is generally from 0.5 to 15% by weight and preferably from 0.5 to 10% by weight.

In the case of an oxidation dyeing treatment, the dyeing composition can be packaged in two parts, the second part being hydrogen peroxide, the two parts being mixed at the time of use.

(e) Hair lacquers, characterised in that they contain an alcoholic or aqueous-alcoholic solution of at least one polymer, optionally together with another resin, this solution being placed in an aerosol container and mixed with a liquefied propellant under pressure.

For example, an excellent aerosol lacquer according to the invention can be obtained by mixing at least one of the specified polymers with an anhydrous aliphatic alcohol such as ethanol or isopropanol and with a propellant or a mixture of such propellants, such as those enumerated above.

In these compositions in the form of hair lacquers, the concentration of polymers is in general from 0.5 to 3% by weight.

Of course, as in the case of the preceding compositions, it is possible to add to these lacquers various ingredients such as dyestuffs or plasticisers

(f) Pre-treatment compositions, in particular in the form of aqueous or aqueous-alcoholic solutions, optionally in the form of aerosols, or in the form of creams or gels, these pre-treatment compositions being intended to be applied to the hair before a shampoo, especially before an anionic or non-ionic shampoo, before an oxidation dyeing treatment followed by an anionic and/or non-ionic shampoo, or before a permanent waving treatment.

In these pre-treatment compositions, the polymer constitutes the active ingredient and its concentration is generally from 0.1 to 15% and in particular from 0.2 to 8% by weight.

The pH of these compositions is near the neutral point and is generally from 3 to 9, especially 6 to 8.

These pre-treatment compositions can contain various adjuvants usually employed in cosmetic compositions for hair, such as plasticisers, perfumes and dyestuffs.

As indicated above, the cosmetic compositions according to the invention can also be used, in the form of a beauty mask or of a make-up product, for the treatment of the skin.

In effect, these compositions make it possible to facilitate the hydration of the skin and thus to prevent its drying-out. Furthermore, an excellent softness to the touch can be imparted to the skin by means of these compositions.

Such cosmetic compositions according to the invention are preferably in the form of creams, gels, emulsions or aqueous, alcoholic or aqueous-alcoholic solutions.

The polymer concentration in these compositions for the skin is generally from 0.1 to 15% by weight and preferably from 0.2 to 6% by weight.

The adjuvants which may be present in these cosmetic compositions include perfumes, dyestuffs, preservatives, thickeners, sequestering agents, emulsifiers and sunlight filters.

These compositions for the skin are, in particular, creams or treatment lotions for the hands or for the face, or anti-sunburn creams, tinted creams, make-up remover milks, foam bath liquids or deodorant compositions.

These compositions can be prepared by conventional methods.

For example, in order to obtain a cream, an aqueous phase in which the polymer and optionally other ingredients or adjuvants are dissolved, and an oily phase, can be emulsified.

The oily phase can consist of for example, paraffin oil, vaseline oil, sweet almond oil, avocado oil, olive oil and esters of fatty acids such as glyceryl monostearate, ethyl palmitate, isopropyl palmitate and alkyl myristates, such as propyl myristate, butyl myristate or cetyl myristate. It is furthermore possible to add fatty alcohols such as cetyl alcohol or waxes such as beeswax.

The polymers can be present in the cosmetic compositions for the skin either as an additive or as a principal active ingredient.

The following Examples further illustrate the present invention.
