Description

Title of the invention: Composition comprising at least one vinyl silicone, at least one mercapto silicone and at least one liquid fatty substance

[0001] The present invention relates to a composition, intended for the cosmetic treatment of keratin fibers, in particular human keratin fibers such as hair, comprising one or more non-acrylate silicones comprising at least one vinyl group, one or more silicones comprising one or more mercapto groups and one or more liquid fats.

[0002] The invention also relates to a cosmetic treatment process for keratin fibers in which said fibers are treated with one or more compositions comprising one or more non-acrylate silicones comprising at least one vinyl group and one or more silicones comprising one or more mercapto groups and one or more liquid fats.

[0003] Hair is generally damaged and weakened by the action of external atmospheric agents such as light and weather, as well as by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perms and / or straightening.

[0004] Hair is thus damaged by these different factors and can eventually become dry, rough, brittle or dull, especially in fragile areas, and more particularly at the ends.

[0005] Thus, to remedy these drawbacks, it is common to use hair care products that employ compositions designed to condition the hair properly, providing it with satisfactory cosmetic properties, including smoothing, shine, softness, suppleness, lightness, a natural feel, and good detangling properties. These compositions are therefore intended to protect, repair, and cosmetically transform the hair.

[0006] These hair care compositions, intended to be applied regularly to the hair, may be, for example, conditioning shampoos, conditioners, masks or serums, and may be in the form of gels, hair lotions and more or less thick care creams.

[0007] However, such compositions still too often lead to effects that are not sufficiently durable and that fade, in particular, with washing.

[0008] There is therefore a real need to implement on keratin fibers, in particular human keratin fibers such as hair, compositions that do not present the disadvantages mentioned above, that is to say, that are capable of conditioning keratin fibers in a durable manner, in particular by giving them lasting cosmetic properties in shampoos. This goal is achieved by the present invention which relates in particular to a composition comprising (i) one or more non-acrylate silicones comprising at least one vinyl group, b) one or more silicones comprising one or more mercapto groups, c) one or more liquid fats.

[0009] The composition according to the invention makes it possible to condition the keratin fibers satisfactorily, in particular by improving detangling and softness to the touch, and this in a durable manner.

[0010] Thus the composition according to the invention makes it possible to give the keratin fibers satisfactory and lasting cosmetic properties to shampoos.

[0011] In particular, the composition according to the invention makes it possible to give improved detangling and softness to the touch, including after five shampoos, compared to a composition comprising the combination of an acrylate functionalized silicone and a silicone functionalized by one or more mercapto groups.

[0012] As a result, keratin fibers can be protected, repaired and cosmetically transformed in a sustainable way.

[0013] The invention also relates to a cosmetic treatment process for keratin fibers, in particular human keratin fibers such as hair, in which said fibers are treated with one or more compositions containing, taken together or separately in said composition(s), the following ingredients: - one or more non-acrylate silicones comprising one or more vinyl groups, - one or more silicones comprising one or more mercapto groups, - one or more liquid fats.

[0014] The process therefore makes it possible to condition keratin fibers in a satisfactory and durable manner.

[0015] Another object of the present invention relates to the use of the composition as defined above for the conditioning of keratin fibers, in particular human keratin fibers such as hair.

[0016] The invention also relates to a multi-compartment device comprising at least a first compartment containing a composition comprising one or more non-acrylate silicones comprising at least one vinyl group and a second compartment containing a composition comprising one or more silicones comprising one or more mercapto groups, at least one of the two compositions comprising one or more liquid fats.

[0017] Other features and advantages of the invention will become more apparent at the read the description and examples that follow.

[0018] In this description, and unless otherwise indicated: The expression "at least one" is equivalent to the expression "one or more" and can be substituted for it; The expression "between" is equivalent to the expression "ranging from" and can be substituted for it, and implies that the boundaries are included; For the purposes of this application, "keratin fibers" means human keratin fibers, and more specifically hair.

[0019] By "non-acrylate silicone" according to the present invention, silicones which do not include an acrylate or methacrylate function are designated.

[0020] Non-acrylate silicones comprising at least one vinyl group may be designated by the term vinyl silicones or vinyl silicones.

[0022] In all that follows, the term silicone, in accordance with general understanding, refers to all organosilicon polymers or oligomers with a linear or cyclic, branched or cross-linked structure, of variable molecular weight, which can be obtained in particular by polymerization and / or polycondensation of suitably functionalized silanes, and which are essentially composed of a repetition of principal motifs in which silicon atoms are linked together by oxygen atoms (siloxane bond -Si-O-Si-), with optionally substituted hydrocarbon radicals being directly linked via a carbon atom to said silicon atoms. The most common hydrocarbon radicals are alkyl radicals, particularly the C1-C10 group, and in particular methyl radicals, fluoroalkyl radicals whose alkyl portion is C1-C10, and aryl radicals, and in particular phenyl radicals.

[0023] The non-acrylate silicone(s) comprising at least one vinyl group include a polysiloxane portion comprising one or more non-(meth)acrylate vinyl reactive groups;

[0138] De façon préférentielle, le photoinitiateur préféré est le composé Ethyl (2, 4, 6-trimethylbenzoyl)-phenyl-phosphinate (TPO-L).

[0139] The photoinitiator(s) is preferably present in the composition, in an amount ranging from 0.001% to 20% by weight, relative to the total weight of the composition, preferably ranging from 0.01% to 10% by weight, preferably ranging from 0.05% to 5% by weight, even better ranging from 0.1% to 3% by weight.

[0140] The process according to the invention optionally includes a step (ii) of light irradiation of the keratin fibers consisting of exposing the keratin fibers to light radiation.

[0141] This step (ii) of light irradiation of the keratin fibers is carried out after the step of application (i) of the composition as described above.

[0142] Preferably, step (ii) of light irradiation of the keratin fibers consists of exposing the keratin fibers to artificial light radiation.

[0143] More preferably, step (ii) of light irradiation of the keratin fibers consists of exposing the keratin fibers to artificial light radiation having a wavelength between 250 and 750 nm, more preferably between 280 and 700 nm, better between 300 and 600 nm, and even better between 350 and 500 nm.

[0144] More specifically, UV-Visible radiation has a wavelength of 385 nm, 405 nm or 455 nm (± 10 nanometers).

[0145] Preferably, step (ii) of light irradiation of the keratin fibers consists of exposing the keratin fibers to artificial light radiation whose irradiance is in the range of 0.1 to 50 W / cm2 of keratin fibers; more preferably from 0.5 to 30 W / cm2; more preferably still from 1 to 10 W / cm2.

[0146] Advantageously, the irradiation step of the process according to the invention is carried out using one or more light sources, preferably one or more electroluminescent sources.

[0147] More advantageously, UV-Visible radiation is emitted by one or more electroluminescent sources composed of one or more electroluminescent elements such as light-emitting diodes (LEDs) or organoelectroluminescent diodes (OLEDs).

[0148] The light-emitting source can be chosen from light-emitting diodes (LEDs) or organo-electro-light-emitting diodes (OLEDs).

[0149] In other words, the irradiation step is implemented by one or more electroluminescent sources, which makes it possible to effectively reduce the processing time of the process.

[0150] In particular, the irradiation source used in the process according to the invention is carried by a clamp as described in French patent application No. 1903781 which can be moved along a wick.

[0151] The UV-Visible radiation can be continuous or pulsed at a pulse frequency from 0.001 to 1000 Hz and preferably from 0.01 to 100 Hz.

[0152] The irradiation source can be moved along a wick one or more consecutive times.

[0153] Preferably, the irradiation step is carried out immediately after the application of the composition to the keratin fibers.

[0154] By "immediately after", we mean less than 5 minutes after the end of the application of the composition.

[0155] Preferably, the duration of exposure of the keratin fibers to light radiation is greater than or equal to 1 second, more preferably between 1 second and 45 minutes, more preferably between 2 seconds and 30 minutes, even better between 5 seconds and 15 minutes.

[0156] The invention also relates to a multi-compartment device comprising a first compartment containing a composition comprising one or more vinyl silicones and a second compartment containing a composition comprising one or more silicones comprising one or more mercapto groups, at least one of the two compositions comprising one or more liquid fats.

[0157] The following examples are given by way of illustration of the present invention.
