Description

1 COMPOSITION COMPRISING AN X COMPOUND AND A Y COMPOUND REACTING TOGETHER

  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 react together, at least one of these compounds being silicone and at least one cationic polymer.

  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 a reactive aminoalkylalkoxysilane 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 the production of film on the skin.  WO 01/96450 and GB 2 407 496 disclose a one-part formulation which comprises a polysiloxane having trialkoxyalkylsilyl 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.  The applicant has just discovered that it is possible to obtain an improvement in the body, mass or volume of the hair and this in a sustainable manner, by combining at least one cationic polymer and at least two compounds X and Y likely to react 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 sheath obtained can provide gloss and conditioning properties, in addition to the remanent styling properties (hold 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 polymer.  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 compounds X and Y being a silicone compound, said compounds X and Y being capable of reacting together by a hydrosilylation, condensation, or crosslinking reaction in the presence of a peroxide, when they are brought into contact with each other and -

amidification of dendrimers and hyperramified polymers with hydroxyl or amino terminal functions, with (meth) acrylic acid.  Dendrimers (from the Greek dendron = tree) are polymeric molecules "tree", that is to say, very branched invented by D.  AT.  Tomalia and his team in the early 90s (Donald A.  Tomalia et al. , Angewandte Chemie, Int.  Engl.  Ed. , flight.  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 patterns 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 STARBUST by the company DENDRITECH.  The hyperbranched polymers are polycondensates, generally of the polyester, polyamide or polyethyleneamine type, obtained from multifunctional monomers, which have a tree structure similar to that of the dendrimers but much less regular than this one (see for example WOA-93 / 17060 and WO 96/12754).  The company PERSTORP markets under the name BOLTORN 30 hyperbranched polyesters.  Under the COMBURST name of the company DENDRITECH are hyperbranched polyethyleneamines.  Hyperramified poly (esteramide) with hydroxyl ends are marketed by 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 association with one or more of the polymers and / or oligomers a) to h) above.  The 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, mention may be made of for example silicas surface-treated, for example with silicone compounds with vinyl groups such as, for example, cyclo tetramethyl tetravinylsiloxane treated silica, silazane compounds such as hexamethyldisilazane.  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 being preferably 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.  Platinum complexes such as those based on chloroplatinic acid hexahydrate and divinyl tetramethyldisiloxane can also be mentioned.  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.  Polymerization inhibitors or retardants, and more particularly catalyst inhibitors, may also be included in 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 alkylhydrogensiloxane 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.  By way of example of a combination of compounds X and Y reacting by hydrosilylation, mention may be made of the following references proposed by
