Description
The present invention relates to new cosmetic compositions for the treatment and care of the hair.
It is well known that the hair is generally sensitized to various extents by the action of atmospheric agents, as well as by the action of treatments such as bleaching, permanent-waving and/or dyeing, so that the hair is often difficult to disentangle and to style.
One of the means generally employed for improving the disentangling and softness of the hair, sensitized or otherwise, consists in using surfactant agents which are cationic in nature.
Such agents have, however, the drawback of weighing down the hair and giving it a greasy appearance.
These same drawbacks are emphasized in the case of fine hair which lacks hold, liveliness and volume.
Rinsing compositions, such as those described in U.S. Pat. No. 4,144,326, based on cationic surfactant agents such as a mixture of dodecyltrimethylammonium and dialkyldimethylammonium chloride, the compositions being thickened with a quaternized cellulose, have already been recommended.
Some rinsing compositions of the prior art contain a quaternary ammonium salt in combination with a cationic cellulose to form a protective film on the hair, as described in Japanese Pat. No. 79/135,234.
All these compositions have, however, the disadvantage of weighing down the hair. In addition, hair treated with such rinsing compositions lacks body and liveliness after drying.
Applicants has now discovered, surprisingly, that, by combining a trimethylalkylammonium chloride, a quaternized hydroxyalkylcellulose polymer and a polyorganosiloxane/polyoxyalkylene copolymer, exceptional properties of body, hold and liveliness which were not possessed by earlier compositions were obtained on the hair.
The subject of the invention hence consists of a cosmetic composition for the treatment and care of the hair, containing, in a cosmetically acceptable aqueous medium, a trimethylalkylammonium chloride, a quaternized hydroxyalkylcellulose polymer and a polyorganosiloxane/polyoxyalkylene copolymer.
The subject of the invention is also a process for treatment and care of the hair employing such a composition.
Other subjects of the invention will become apparent on reading the description and the examples which follow.
The cosmetic composition intended for the treatment and care of the hair, according to the invention, is essentially characterized in that it contains, in a cosmetically acceptable aqueous medium:
at least one cationic surfactant agent of formula (I): ##STR2## in which R.sub.1 denotes a mixture of alkenyl and/or alkyl radicals having from 14 to 22 carbon atoms, derived from tallow fatty acids;

The cellulose derivatives are preferably chosen from hydroxyalkylcelluloses such as hydroxymethyl- or hydroxyethyl- or hydroxypropylcelluloses.
The especially preferred products consist of the copolymer of hydroxyethylcellulose grafted by a free-radical method with diallyldimethylammonium chloride, sold by the company NATIONAL STARCH under the name "CELQUAT L 200" or "CELQUAT H 100".
The polyorganosiloxane/polyoxyalkylene copolymer used according to the invention is preferably an alkoxylated polydi(C.sub.1 -C.sub.4 alkyl)siloxane in which some of the di(C.sub.1 -C.sub.4 alkyl)siloxane units are modified by substitution of one of the alkyl groups with hydroxy(C.sub.1 -C.sub.4 alkyl) groups, and more especially an ethoxylated polydimethylsiloxane in which some of the dimethylsiloxane units are modified by the substitution of one of the methyl groups with 3-hydroxypropylmethyl groups, such as the products sold by the company UNION CARBIDE under the name SILWET.TM. The molecular weight of these copolymers is between 500 and 10,000, and preferably between 550 and 6,000.

A more especially preferred cosmetic composition for hair treatment, according to the invention, contains, in a cosmetically acceptable aqueous medium:
0.7 to 2% by weight of cationic surfactant agent of formula (I);
1 to 2% by weight of cellulose ether polymer derived from quaternary ammonium, especially the product sold by the company UNION CARBIDE under the name JR-400; and
0.6 to 1% by weight of ethoxylated dimethylsiloxane/3-hydroxypropylmethylsiloxane copolymer, especially the product sold by the company UNION CARBIDE under the name SILWET 7600.
The cosmetic compositions for the treatment and care of the hair are presented in the form of an aqueous solution, thickened or otherwise, a cream, an emulsion, a gel, an aerosol foam or a spray.
The aqueous solutions contain either water or a water/solvent mixture. The solvents are preferably chosen from monohydric alcohols, polyhydric alcohols, glycol ethers and fatty acid esters. There may be mentioned, more especially, lower alcohols such as ethanol, n-propanol, isopropanol and n-butanol, polyhydric alcohols such as ethylene glycol, diethylene glycol and propylene glycol, and glycol ethers such as mono- or diethylene glycol alkyl ethers.
These compositions can contain, in addition to the compounds mentioned in the invention, other cationic surfactant agents and agents customarily used in cosmetics, such as perfumes, colourings, preservatives, sequestering agents, thickeners, emulsifiers, emollients and other adjuvants customarily used in hair-care compositions. They do not contain active substances having detergent, wetting and foaming properties, enabling the hair to be cleansed.
The cosmetic compositions according to the invention which are presented in thickened or gel form contain thickeners in the presence or absence of solvents. The thickeners are preferably chosen from sodium alginate, gum arabic, cellulose derivatives such as methylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxyporpylmethylcellulose and carboxymethylcellulose, guar gum or its derivatives, xanthan gum or scleroglucans. It is also possible to obtain a thickening of the compositions by mixing polyethylene glycol and polyethylene glycol stearate or distearate, or by a mixture of amide and phosphoric ester.
The concentration of thickener can vary from 0.1 to 30% by weight, and preferably between 0.2 and 15% by weight, relative to the total weight of the composition.
The different cosmetic compositions for the treatment and care of the hair may be presented under pressure, in the form of an aerosol can, and used in the form of an aerosol foam. They are packaged in this case in the presence of one or more propellant gases.
The propellant gases used for pressurizing the cosmetic formulations are present in proportions not exceeding 25%, and preferably 15%, relative to the total weight of the composition. By way of propellant gases, it is possible to use carbon dioxide, nitrogen, nitrous oxide, volatile hydrocarbons such as butane, isobutane, propane and mixtures thereof, and non-hydrolysable chlorinated and/or fluorinated hydrocarbons such as, for example, those sold under the name FREON by the company DU PONT DE NEMOURS and belonging, in particular, to the categories of fluorochlorohydrocarbons such as dichlorodifluoromethane or Freon 12 and dichlorotetrafluoroethane or Freon 114. These propellants may be used alone or in combination; there may be mentioned in particular, a mixture of Freon 114/12 in proportions varying between 40:60 and 80:20.
The pH of these compositions may be adjusted with an alkalinizing or acidifying agent customarily used in the cosmetic field. The pH is generally between 3 and 10, depending on the application envisaged. It is adjusted using alkalinizing or acidifying agents that are well known in the state of the art.
The cosmetic compositions are intended for the treatment and care of the hair. A cosmetic treatment denotes a treatment intended for improving the appearance, feel and shape of the hair.
The process for treatment of the hair, according to the invention, consists in applying the cosmetic compositions as defined above on the hair, and in following this, where appropriate after an exposure time of 1 to 30 minutes, with a rinse.
The cosmetic compositions according to the invention are preferably used as a product to be rinsed before or after shampooing, before of after dyeing or bleaching, before or after permanent-waving or straightening.
The examples which follow are designed to illustrate the invention, no limitation of the latter being implied.
