Cosmetic composition based on guar gum and silicones

Abstract

A non-washing cosmetic composition comprising, in a cosmetically acceptable medium, at least one guar gum and at least one oxyalkylenated silicone in a guar gum/silicone weight ratio of less than or equal to 5:1, and a process for the treatment of the skin or keratinous fibres comprising the step of applying a non-washing cosmetic composition as defined above to the skin or to the keratinous fibres and optionally rinsing the skin or keratinous fibres with water.

Description

The present invention relates to cosmetic compositions containing, in a cosmetically acceptable medium, at least one guar gum and at least one oxyalkylenated silicone in a guar gum/silicone weight ratio of less than or equal to 5.

Another subject of the invention is a process for the non-washing cosmetic treatment of keratinous material, such as the hair or the eyelashes, characterized in that it includes applying a cosmetic composition as defined above to the keratinous material, optionally followed by rinsing with water. As is readily understood by those skilled in the art, non-washing compositions do not have detergent properties, i.e., these compositions contain less than 3% detergent surfactants.

Formulations which make it possible to fix and to condition the hair are already known in the state of the art. Compositions in gel form which are generally based on crosslinked acrylic polymers have already been used with this aim. However, these compositions have the drawback of leaving an undesirable deposit on the hair, which is detrimental to the cosmetic properties thereof: thus, at the end of the operation, the hair lacks shine, is coarse or is sticky.

The use of silicone-containing derivatives in combination with polymer resins is known in the preparation of cosmetic compositions for holding the hairstyle. It has been observed that these silicone-containing derivatives clearly improve the properties of disentangling, softness and shine of hair treated using these compositions, although these properties are generally inferior to the properties of the silicone derivative used alone.

Unfortunately, however, these silicone-containing derivatives are not generally favourable towards the fixing power of these compositions, which fixing power is provided by the polymer resin.

In particular, oxyalkylenated silicones are generally known for not imparting hold to the head of hair. Guar gums have been described in the art as being thickeners. In particular, they have been used to thicken conditioning compositions containing volatile silicones in application EP-A-0,035,901.

The inventors have discovered that the combination of guar gums with oxyalkylenated silicones in a specific ratio led, surprisingly and unexpectedly, to particularly advantageous properties, in particular to an improvement in the hold of the hairstyle over time. The head of hair has more volume, and the hair is shiny and has a natural feel. This discovery forms the basis of the present invention.

The subject of the present invention is thus novel non-washing cosmetic compositions for keratinous material such as the hair, the skin or the eyelashes, characterized in that they contain, in a cosmetically acceptable non-detergent medium, at least one guar gum and at least one oxyalkylenated silicone in a guar gum/silicone weight ratio of less than or equal to 5:1.

Other characteristics, aspects, subjects and advantages of the invention will emerge even more clearly on reading the description and the examples which follow.

The guar gums which may be used according to the invention are preferably nonionic or cationic. According to the invention, unmodified or chemically modified nonionic guar gums are preferably used. Unmodified nonionic guar gums are, for example, the products sold under the name VIDOGUM GH 175 by the company Unipectine and under the name JAGUAR C by the company Meyhall. Modified nonionic guar gums which may be used according to the invention are preferably modified with C.sub.1 -C.sub.6 hydroxyalkyl groups. Among the hydroxyalkyl groups which may be mentioned by way of example are hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups.

These guar gums are well known in the state of the art and may be prepared, for example, by reacting corresponding alkene oxides, for example such as propylene oxides, with guar gum so as to obtain a guar gum modified with hydroxypropyl groups.

The degree of hydroxyalkylation, which corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxyl functions present on the guar gum, preferably ranges from 0.4 to 1.2. Such nonionic guar gums optionally modified with hydroxyalkyl groups are sold, for example, under the trade names JAGUAR HP8, JAGUAR HP60 and JAGUAR HP120, JAGUAR DC 293 and JAGUAR HP 105 by the company Meyhall, or under the name GALACTASOL 4H4FD2 by the company Aqualon.

The cationic guar gums which may more particularly be used according to the invention are guar gums containing trialkylammonium cationic groups. Preferably, 2 to 30%, and even more preferably 5 to 20%, in numerical terms, of the hydroxyl functions of these guar gums bear trialkylammonium cationic groups.

Among these trialkylammonium groups, there may most particularly be mentioned trimethylammonium and triethylammonium groups. Even more preferably, these groups represent from 5 to 20% by weight relative to the total weight of the modified guar gum.

According to the invention, a guar gum modified with 2,3-epoxypropyltrimethylammonium chloride is preferably used.

These guar gums modified with cationic groups are products which are already known per se and are described, for example, in U.S. Pat. Nos. 3,589,578 and 4,031,307, the disclosures of which are expressly incorporated by reference herein. Such products are, moreover, sold in particular under the trade names JAGUAR C13 S, JAGUAR C 15 and JAGUAR C 17 by the company Meyhall.

A nonionic guar gum is preferably used and, among these nonionic guar gums, guar gums modified with hydroxyalkyl groups are more particularly used.
