Description

COMPOSITION COMPRISING AN X-COMPOUND AND A Y-COMPOUND REACTING TOGETHER AT LEAST ONE OF WHICH IS SILICONE AND ONE

CATIONIC SURFACTANT

The subject of the present invention is a composition for the treatment of keratinous fibers, and in particular human keratinous fibers such as the hair, comprising at least two compounds X and Y, capable of reacting together, at least one of these compounds being silicone and at least 0.1% by weight relative to the total weight of the composition of at least one cationic surfactant.

In the field of cosmetics, it is sought to modify the surface properties of keratinous fibers such as the hair, for example to provide the hair with a conditioning effect such as softness, or shine or a styling effect to bring the body, mass or volume to the hair.

To do this, cosmetic compositions based on conditioning or styling agents such as silicones or polymers having a high affinity for keratinous fibers, and especially for the hair, are generally used. However, these conditioning or styling agents tend to be eliminated during washing with shampoos, making it necessary to renew the applications of the compositions on the hair.

A disadvantage related to the use of these hair compositions lies in the fact that the cosmetic effects conferred by such compositions tend to disappear, especially from the first shampoo.

In order to overcome this disadvantage, it is conceivable to increase the remanence of the polymer deposit by directly effecting a polymerization of certain monomers in the hair. US 4,344,763 discloses a hair-fixing composition from an aminoalkylalkoxysilane reactive silicone and an ester titanate. However, the cladding obtained does not give total satisfaction with external agents such as washing and transpiration. In addition, the sheath obtained is sensitive to fatty substances such as sebum. Documents WO 01/96450, GB 2 407 496 and EP 465 744 describe the use of particular reactive silicones for producing film on the skin. WO 01/96450 and GB 2 407 496 disclose a one-part formulation which comprises a polysiloxane having koxyalkylsilyl end groups, a catalyst, a solvent and optionally an alkoxysilane and fillers. These compositions make it possible to obtain a film on the skin by condensation. EP 465 744 describes the use of polysiloxane with unsaturated aliphatic groups for producing medical devices for topical use. The object of the present invention is to develop a hair treatment composition which makes it possible to obtain durable hair fixing properties while having good cosmetic properties, these properties being themselves remanent to shampoos.

The Applicant has just discovered that it is possible to obtain an improvement in the body, the mass or the volume of the hair and this in a sustainable way, associating at least 0.1% by weight with respect to the total weight of the hair. composition of at least one cationic surfactant and at least two compounds X and Y capable of reacting together which will be described later, the treated hair having more very good cosmetic properties such as detangling and smoothing to the touch.

Indeed, the application of a composition comprising such an association leads to the formation of a coating or remanent coating including shampoos, even after several washes of the hair.

The sheathing obtained can provide shine and conditioning properties, in addition to the residual styling properties (maintenance and volume).

In addition, the hair can be styled without difficulty.

In addition, removing makeup from this coating or sheathing is improved by the presence of the cationic surfactant. The present invention relates to a cosmetic composition for the treatment of keratinous fibers comprising:

at least one compound X and at least one compound Y, at least one of the compounds X and Y being a silicone compound, said compounds X and Y being capable of reacting together by a hydrosilylation reaction, condensation, or crosslinking in the presence of a peroxide, when they are brought into contact with each other; and

at least 0.1% by weight relative to the total weight of the composition of at least one cationic surfactant. Preferably, the composition is in the form of a water-in-oil or oil-in-water emulsion.

Another subject of the invention relates to a kit comprising at least two compounds X and Y, capable of reacting together, at least one of these compounds being silicone and at least 0.1% by weight relative to the total weight of the composition of at least one cationic surfactant, the compounds of type X and Y being in two separate compositions, the cationic surfactant (s) being in one or other of the compositions or in a third composition.

Dendrimers (from the Greek dendron = tree) are polymeric molecules

"tree", that is to say very branched invented by D. A. Tomalia and his team in the early 90s (Donald A. Tomalia et al., Angewandte Chemie,

Int. Engl. Ed., Vol. 29, No. 2, pp. 138-175). These are structures built around a generally versatile central pattern. Around this central motif are chained, according to a perfectly determined structure, branched chain extension units thus giving rise to symmetrical, monodisperse macromolecules having a well-defined chemical and stereochemical structure. Dendrimers of the polyamidoamine type are marketed for example under the name Starburst ^® by the company DENDRITECH.

The hyperbranched polymers are polycondensates, generally of polyester, polyamide or polyethyleneamine type, obtained from multifunctional monomers, which have a tree structure similar to that of dendrimers but beau∞up less regular than this one (see for example WO-A-93/17060 and WO 96/12754).

The company PERSTORP markets under the name BOLTORN ^® hyperbranched polyesters. Can be found under the name ^® COMBURST the company DENDRITECH hyperbranched polyethylene amines. Poly (esteramide) hyperbranched hydroxyl end groups are marketed by the company DSM under the name HYBRANE ^®.

These dendrimers and hyperbranched polymers esterified or amidified with acrylic and / or methacrylic acid are distinguished from the polymers described under points a) to h) above by the very large number of ethylenic double bonds present. This high functionality, most often greater than 5, makes them particularly useful by allowing them to play a role of "crosslinking node", that is to say of multiple crosslinking site.

These dendritic and hyperbranched polymers can thus be used in combination with one or more of the polymers and / or oligomers a) to h) above.

1a Additional reactive compounds

According to one embodiment, the composition according to the invention may further comprise an additional reactive compound such as:

the organic or inorganic particles comprising on their surface at least 2 unsaturated aliphatic groups, for example silicas surface-treated for example with silicone compounds with vinyl groups, such as, for example, cyclobutyltetramethyl tetravinylsiloxane-treated silica,

silazane compounds such as hexamethyldisilazane.

1 b Catalyst

The hydrosilylation reaction is advantageously carried out in the presence of a catalyst which may be present in the composition according to the invention, the catalyst preferably being based on platinum or tin.

There may be mentioned, for example, platinum catalysts deposited on a silica gel or charcoal powder (charcoal) support, platinum chloride, platinum and chloroplatinic acid salts. The chloroplatinic acids are preferably used in hexahydrate or anhydrous form, which is easily dispersible in organosilicone media. There may also be mentioned platinum complexes such as those based on chloroplatinic acid hexahydrate and divinyl tetramethyldisiloxane. The catalyst may be present in the composition according to the present invention in a content ranging from 0.0001% to 20% by weight relative to the total weight of the composition.

It is also possible to introduce polymerization inhibitors or retarders, and more particularly catalyst inhibitors, into the composition of the invention, in order to increase the stability of the composition over time or to retard the polymerization. In a nonlimiting manner, mention may be made of cyclic polymethylvinylsiloxanes, and in particular tetravinyl tetramethylcyclotetrasiloxane, and acetylenic alcohols, which are preferably volatile, such as methylisobutynol. The presence of ionic salts, such as sodium acetate, in the composition may influence the rate of polymerization of the compounds.

Advantageously, the compounds X and Y are chosen from silicone compounds capable of reacting by hydrosilylation; in particular, compound X is chosen from polyorganosiloxanes comprising units of formula (I) described above and compound Y is chosen from organosiloxanes comprising alkylhydrogenosiloxane units of formula (III) described above.

According to one particular embodiment, the compound X is a polydimethylsiloxane with terminal vinyl groups, and the compound Y is methylhydrogensiloxane.

As an example of a combination of compounds X and Y reacting by hydrosilylation, mention may be made of the following references proposed by Dow Corning: DC 7-9800 Soft Skin Adhesive Parts A & B, as well as mixtures A and B following products prepared by Dow Corning:

2 / X and Y compounds likely to react by condensation

According to this embodiment, compounds X and Y are capable of reacting by condensation, either in the presence of water (hydrolysis) by reaction of 2 compounds bearing alkoxysilane groups, or by so-called "direct" condensation by reaction of a compound carrier of alkoxysilane group (s) and a silanol group-bearing compound (s) or by reaction of 2 silanol (s) group-bearing compounds.

When the condensation is carried out in the presence of water, this may be in particular the ambient humidity, the residual water of the keratinous fibers, or the water supplied by an external source, for example by prior wetting of the keratinous fibers ( for example by a mist maker).

In this condensation reaction mode, the compounds X and Y, which are identical or different, may therefore be chosen from silicone compounds whose main chain comprises at least two alkoxysilane groups and / or at least two silanol groups (Si-OH), side and / or at the end of the chain. According to an advantageous embodiment, the compounds X and / or Y are chosen from polyorganosiloxanes comprising at least two alkoxysilane groups. By "alkoxysilane" group is meant a group comprising at least a portion -Si-OR, R being an alkyl group comprising from 1 to 6 carbon atoms. The compounds X and Y are in particular chosen from polyorganosiloxanes comprising alkoxysilane end groups, more specifically those which comprise at least 2 terminal alkoxysilane groups, preferably terminal trialkoxysilanes.

These compounds X and / or Y preferably comprise, in a majority manner, units of formula:
