Description

1 COMPOSITION COMPRISING X-COMPOUND AND Y COMPOUND HAVING AT LEAST ONE

  The subject of the present invention is a composition for dyeing keratinous fibers, and in particular human keratinous fibers such as the hair, comprising at least two compounds X and Y that are capable of reacting together. at least one of these compounds being silicone, at least one hydrophilic direct dye whose IogP is less than or equal to 2 and preferably at least one organic solvent.

  Since a long time, one seeks to modify the color of the hair and in particular to mask the white hair. To do this, several technologies have been developed. It is known to dye keratinous fibers, and in particular human keratin fibers such as hair, with dyeing compositions containing direct dyes. The conventional dyes which are used are in particular nitrobenzene, anthraquinone, nitropyridine, azo, xanthene, acridine, azine or triarylmethane type dyes or natural dyes. These dyes may be nonionic, anionic, cationic or amphoteric.

  These dyes, which are colored and coloring molecules having an affinity for keratinous fibers, are applied for the time necessary to obtain the desired coloration, and then rinsed.  The resulting dyes are particularly chromatic colorations which are however temporary or semi-permanent because the nature of the interactions which bind the direct dyes to the keratinous fiber, and their desorption of the surface and / or the core of the fiber are responsible for their low dyeing power and their poor resistance to washes or perspiration.  Furthermore, it is known to stain keratin fibers permanently by oxidation dyeing.  This staining technique consists in applying to the keratinous fibers a composition containing dye precursors such as oxidation bases and couplers.  These precursors under the action of an oxidizing agent will form in the hair one or more colored species.  2910297 2 The variety of molecules used at the level of oxidation bases and couplers makes it possible to obtain a rich palette of colors.  The resulting colorations are permanent, strong, and resistant to external agents, including light, weather, washing, perspiration and rubbing.  However, this type of coloration leads to degradation of the fiber due to the use of an oxidizing agent.  There is still a need to develop new direct dyeing compositions to obtain various shades, in particular pastel shades and which exhibit good toughness, especially to external agents such as light, shampoo, sweat while preserving the quality of keratin fibers.  In particular, there is a need to develop coloring compositions which make it possible to obtain colorations having a tenacity close to oxidation coloring without the drawbacks associated with the presence of an oxidizing agent, while having powerful shades and / or Chromatic.  This object is achieved with the present invention which relates to a composition for dyeing 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 peroxide when they are brought into contact with each other; at least one hydrophilic direct dye whose IogP is less than or equal to 2; and optionally at least one organic solvent.  The composition of the invention makes it possible to obtain varied shades and intense colorations.  In addition, the coloration obtained is very resistant to external agents, especially repeated washing.  The hair also has good cosmetic properties, in particular they remain perfectly individualized and can be easily capped.  The subject of the present invention is also a process for dyeing keratin fibers, which comprises applying to the keratinous fibers at least two compounds X and Y that are capable of reacting together, at least one of these compounds being silicone-coated. at least one hydrophilic direct dye whose IogP is less than or equal to 2 and preferably containing at least one organic solvent.  Another subject of the invention relates to a kit for the dyeing 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, at least one hydrophilic direct dye whose log P is less than or equal to 2 and optionally at least one organic solvent.  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 include polar groups which may be selected from the following groups -COOH, -COO-, -COO-, -OH, -NH2, -NH-, -NR-, -SO3H, -SO3-, -OCH2CH2-, -O-CH2CH2CH2-, -O-CH2CH (CH3) -, -NR3 +, -SH, -NO2, I, Cl, Br, -CN, -PO43-, -CONH-, -CONR-, -CONH2, -CSNH -, -SO2-, -SO-, -SO2NH-, -NHCO-, -NHSO2-, -NHCOO-, -OCONH-, -NHCSO- and -OCSNH- with R representing an alkyl group.  According to another embodiment, at least one of the compounds X and Y is a polymer whose main chain is formed mainly of organosiloxane units.  Among the silicone compounds mentioned below, some may have both film-forming and adhesive properties, for example according to their proportion of silicone or according to 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, it is in particular the case for the so-called "room temperature vulcanization" reactive elastomeric silicones.  Compounds X and Y may react together at a temperature ranging from room temperature to 180 ° C.  Advantageously, the compounds X and Y are capable of reacting together at ambient temperature (20 ° 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 are capable of reacting by hydrosilylation, this reaction can be schematically simplified as follows: ## STR1 ## -CH2-W iCH2 = CH2-W with W representing a carbon chain and / or silicone containing one or more unsaturated aliphatic groups.  In this case, the compound X may be chosen from silicone compounds comprising at least two unsaturated aliphatic groups.  By way of example, the compound X may comprise a silicone main chain whose unsaturated aliphatic groups are pendant to the main chain (side group) or located at the ends of the main chain of the compound (terminal group).  In the remainder of the description, these particular compounds will be called polyorganosiloxanes with unsaturated aliphatic groups.  According to one embodiment, the compound X is chosen from polyorganosiloxanes comprising at least two unsaturated aliphatic groups, for example two or three vinyl or allylic groups, each bonded to a silicon atom.  According to an advantageous embodiment, the compound X is chosen from polyorganosiloxanes comprising siloxane units of formula: .  Wherein R represents a monovalent hydrocarbon group, linear or cyclic, comprising from 1 to 30 carbon atoms, preferably from 1 to 20, and more preferably from 1 to 10 carbon atoms, as for example a short-chain alkyl radical, for example comprising from 1 to 10 carbon atoms, in particular a methyl radical or a phenyl group, preferably a methyl radical;

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 10 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 STARBUST 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 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 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 by 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 compositions comprising compound X and / or Y may further comprise additional reactive compounds such as: organic or inorganic particles comprising on their surface at least 2 unsaturated aliphatic groups, there may be mentioned, 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 one or other of the compositions comprising compound X and / or compound Y or in a separate composition, 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 any one of the compositions useful in the present invention in a content of from 0.0001% to 20% by weight based on 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, the

compound containing alkoxysilane group (s) and a silanol group (s) carrier compound (s) or by reaction of 2 compounds carrying group (s) silanol (s).  When the condensation is carried out in the
