Description

COMPOSITION COMPRISING A SILICONE COMPOUND AND A CYANOACRYLATE MONOMER

  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.  The hair is generally damaged and weakened by the action of external atmospheric agents such as light and weather, and by mechanical or chemical treatments such as brushing, combing, discoloration, perms and / or dyes.  As a result, the hair is often difficult to discipline, in particular they are difficult to disentangle or comb, and hair, even abundant, difficult to maintain a good looking hairstyle due to the fact that the hair lack of vigor, volume and nervousness.  Thus, to remedy this, it is now customary to use hair styling products that can condition the hair by providing them including body, mass, shine or volume.  These styling products are generally cosmetic hair compositions comprising one or more polymers which have an affinity for the hair and which most often have the function of forming a film on their surface in order to modify their surface properties, in particular for conditioning them.  By obtaining such an effect, it is known in particular to use polysiloxanes, in particular those described in documents FR 2 799 955, FR 2 799 956, FR 2 799 970 and FR 2 799 971.  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.  It is also known to perform hair cladding from a composition comprising an electrophilic monomer of cyanoacrylate type, especially in patent applications FR 2 833 489.  Such a composition makes it possible to obtain perfectly shiny and non-oily hair.  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.  WO01 / 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 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 process which makes it possible to obtain a durable fixation of the hair while retaining good cosmetic properties.  Thus, the subject of the invention is a composition for treating 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, the compounds X and Y being capable of to react together by a hydrosilylation reaction, a condensation reaction, or a crosslinking reaction in the presence of a peroxide, when they are brought into contact with each other, and at least one cyanoacrylate monomer.  The invention also relates to a hair treatment method which consists in applying to the hair at least one compound X and at least one compound Y, at least one of the compounds X and Y being a silicone compound, the compounds X and Y being capable of reacting together by a hydrosilylation reaction, a condensation reaction, or a crosslinking reaction in the presence of a peroxide, when they are brought into contact with each other, and at least a cyanoacrylate monomer.  The subject of the invention is also the use of the combination of compounds X, Y and cyanoacrylate monomers as described above for the treatment of hair, in particular for obtaining a shampoo-resistant sheath of the hair .  Another object of the invention relates to a kit for the treatment of keratinous fibers comprising at least two compositions packaged separately, the kit comprising at least two compounds X and Y, able to react together, at least one of these compounds. being silicone, and at least one cyanoacrylate monomer.  The method of the invention makes it possible to obtain in situ a remanent coating which is homogeneous, smooth and has excellent adhesion to hair.  On the other hand, it has surprisingly been found that the hair remains perfectly individualized, can be capped without problems and that the styling properties provided to the fiber are remanent to the shampoos.  Compounds X and Y Silicone compound is understood to mean a compound comprising at least two organosiloxane units.  According to one particular embodiment, the compounds X and the compounds Y are silicone.  Compounds X and Y may be amino or non-amino.  They may comprise polar groups which may be chosen from the following groups -COOH, -COO-, -COO-, -OH, -NH 2, -NH-,

units.  Of the silicone compounds mentioned hereinafter, some may have both film-forming and adhesive properties, depending, for example, on their proportion of silicone or whether they are used in admixture with a particular additive.  It is therefore possible to modulate the film-forming properties or the adhesive properties of such compounds according to the intended use, this is particularly the case for the so-called "room temperature vulcanization" reactive elastomeric silicones.  Compounds X and Y may react together at a temperature varying between room temperature and 180 C.  Advantageously, compounds X and Y are capable of reacting together at room temperature (20 5 C) and atmospheric pressure, advantageously in the presence of a catalyst, by a hydrosilylation reaction or a condensation reaction, or a reaction of crosslinking in the presence of a peroxide.  1- X and Y compounds capable of reacting by hydrosilvlation According to one embodiment, the compounds X and Y

of dendrimers and hyperbranched polymers with hydroxyl or amino terminal functions, with (meth) acrylic acid; .  Dendrimers (from the Greek dendron = tree) are "tree", that is, highly branched, polymer molecules 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 units thus giving rise to symmetrical, monodisperse macromolecules having a well defined chemical and stereochemical structure.  Dendrimers of 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, WO-A- 93/17060 and WO 96/12754).  The company PERSTORP markets under the name BOLTORN 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 combination with one or more of the polymers and / or oligomers a) to h) above.  According to one embodiment, the composition according to the invention may further comprise an additional reactive compound such as: organic or inorganic particles comprising at 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, cyclotetramethyltetravinylsiloxane-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.  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 a 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 the company Dow Corning: DC 7-9800 Soft Skin Adhesive Parts A & B, as well as mixtures A and B following prepared by Dow Corning: MIXTURE A: Ingredient (INCI name) N CAS Content (%) Dimethyl Siloxane
