Hair Treatment Description
The present invention relates to cosmetic compositions for the treatment and care of hair, containing (a) at least one cationic surface-active agent which can be dispersed in water, (b) at least one water soluble quaternised cationic polymer of the ionene type and (c) at least one cationic silicone polymer.

It is well known that hair is generally sensitive to atmospheric conditions, as well as to treatments such as bleaching, permanent waving and/or dyeing, with the result that hair is often difficult to untangle and dress.

One of the means which is widely employed for improving the untangling and the softness of sensitised hair consists of the use of cationic surface-active agents.

The use of cationic surface-active agents however has the disadvantage of making the hair heavier and giving it a greasy appearance.

These disadvantages are emphasised in the case of fine hair which is lacking in body, liveliness and form-retention.

It has already been proposed to improve the untangling and the softness of hair by using cationic polymers which do not have the disadvantage of making hair heavier while having durable effects. However, the untangling which is obtained is inferior to that imparted by a cationic surface-active agent.

Among the cationic polymers which have already been recommended for hair conditioning, we have already described quaternised polymers of the ionene type, as, for example, in French Pat. No. 2,270,846. These polymers facilitate the untangling of wet, natural, bleached or permanent-waved hair and help remove faults from hair sensitised by treatments such as bleaching, permanent waving and/or dyeing, while not making dry hair heavier, and consequently making it easier to obtain hairstyles with body, while retaining liveliness and glossy appearance.

There have also been proposed compositions of a cationic surface-active agent with a cationic polymer.

It is not possible to obtain the maximum possible effect from these combinations of the cationic surface-active agent and cationic polymer, because in the majority of cases the deposition of the cationic surface active agent slows down the deposition of the cationic polymer.

There have been proposed, in French Patent Application No. 2,463,612, hair-care compositions combining cationic polymers of the MERQUAT 100 and 550, or ONAMER type, and/or quaternised polyvinylpyridines with cationic silicone polymers of the Amodimethicone type to produce some durability of the cosmetic properties.

However, these compositions still have the disadvantage that they do not adequately provide the required properties of untangling, liveliness and form-retention.

We have surprisingly discovered that by associating in a hair-care cosmetic composition (a) a cationic surface-active agent which can be dispersed in water, (b) a water-soluble quaternised polymer of the ionene type, and (c) a cationic silicone polymer, preferably of the Amodimethicone type, an optimum and simultaneous deposition of these three components on the hair was promoted and a cosmetic composition was obtained which was noticeably superior to those known hitherto, insofar as the properties of untangling, softness, brilliance, lightness, liveliness, body, pleasant touch and appearance were concerned, while retaining the advantage of not making the hair heavier, and making it antistatic, these cosmetic effects being moreover durable.

In the case of sensitised hair, the composition according to the invention makes hair more resistant to repeated applications of products which modify the keratin fibre such as colorants, bleaches, permanent waving compositions and hair-straighteners.

Thus, the invention provides a cosmetic hair-care composition containing (a) at least one cationic surface-active agent which can be dispersed in water, (b) at least one water-soluble quaternised polymer of the ionene type and (c) at least one cationic silicone polymer.

The invention also provides a process for treating hair comprising applying to the hair an appropriate quantity of a composition as referred to above.

A particularly preferred cosmetic hair-care composition according to the invention contains:

(a) at least one cationic surface-active agent of the formula (I): ##STR15## in a proportion which is from 0.5 to 1.5% of the total weight of the composition,

(b) at least one quaternised polymer of the ionene type of the formula: ##STR16## in a proportion which is from 0.1 to 0.6%, and

(c) at least one silicone polymer such as DC 929 or DOW CORNING Q2 7224 of the DOW Company or such as "UCAR SILICONE ALE 56" of UNION CARBIDE in a proportion which is from 0.5 to 1.5% of the total weight of the composition.

The cosmetic hair-care compositions according to the invention are generally in the form of aqueous or aqueous-alcohol dispersions, which may be thickened or unthickened, creams, gels, aerosol foams or sprays.

In addition to the cationic surface-active agent which can be dispersed in water, the quaternised polymer of the ionene type and the silicone polymer, they may also contain adjuvants conventionally employed in cosmetics such as fragrances, colorants, preserving agents, sequestering agents, thickeners, emulsifiers, softeners and foam stabilisers, depending on the intended application.

The cosmetic hair-care compositions according to the invention may generally be applied in the form of shampoo, rinsing products to be applied before or after shampooing, before or after tinting or bleaching, before or after permanent waving or straightening, products for setting or brushing, conditioning compositions, restoring compositions and compositions for permanent-waved hair.

When the composition forms a shampoo, it also contains one or more anionic, non-ionic, amphoteric and/or zwitterionic surface-active agents, the total concentration of the surface-active agent being generally from 3 to 50% and preferably from 3 to 20% by weight of the total weight of the composition.

The pH is generally from 3 to 10.

The compositions according to the invention may also be in the form of rinses. These products may be aqueous or aqueous-alcohol dispersions, emulsions, thickened compositions or gels.

When the compositions are in the form of emulsions, they may be non-ionic or anionic.

When the compositions are in a thickened form or are gels, they contain thickeners in the presence or absence of solvents.

The thickeners which can be employed may, for example, be sodium alginate or gum arabic, cellulose derivatives such as methylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, guar gum or its derivatives. A thickening of the compositions may also be produced by mixing polyethylene glycol and polyethylene glycol stearate or distearate or by a mixture of a phosphoric ester and an amide.

The concentration of thickening agent is preferably from 0.5 to 30% by weight and more preferably from 0.5 to 15% by weight.

The pH of the rinses is generally from 3 to 9.

When the compositions according to the invention are in the form of products for hairdressing or styling or setting, they usually incorporate, in an aqueous or aqueous-alcohol dispersion, anti-foam agents and non-ionic polymers.

The combination according to the invention may also be employed in compositions for curling permanent-waved hair. The conventional technique for these permanent waves consists in applying, in a first stage, a composition containing a agent and then, after having rinsed the hair if appropriate, applying a composition containing an oxidising agent. According to the invention, at least one of the two compositions contains the combination such as described earlier.

When the compositions according to the present invention are distributed in the form of an aerosol foam, the propellant gasses employed to pressurize the cosmetic formulations are generally present in proportions which do not exceed 25% and preferably do not exceed 15% relative to the total weight of the composition. Examples of propellent gases which may be employed are carbon dioxide, nitrogen, nitrous oxide, volatile hydrocarbons such as butane, isobutane, propane and their mixtures, non-hydrosable chlorinated and/or fluorinated hydrocarbons such as, for example, those sold under the name FREON by the Company Du Pont de Nemours and belonging to the classes of fluorochlorohydrocarbons such as dichlorofluoromethane or Freon 12, dichlorotetrafluoroethane or Freon 114. These propellants may be employed alone or combined; mention can be made in particular of the mixture of Freon 114-12 in proportions varying between 40:60 and 80:20.

The pH of the composition according to the invention is generally from 3 to 10, depending on the intended application. It is adjusted with the aid of alkalysing or acidifying agents which are well known in the state of the art.
