Description

Description Title of the invention: Cosmetic composition comprising at least one cationic surfactant, at least one fatty alcohol, at least one ester of glycerol and a particular combination of silicones

[0001] — The present invention relates to a cosmetic composition comprising at least a cationic surfactant, at least one fatty alcohol, at least one glycerol ester and a special combination of silicones.

[0002] = The invention also relates to a method for the cosmetic treatment of ke-fibers ratiniques in which such a composition is applied to said fibers.

[0003] — The invention further relates to the use of the composition according to the invention for the conditioning and / or care of keratin fibers, in particular hair.

[0004] Hair is generally damaged and weakened by the action of atmospheric agents- external spherical such as light and weather, as well as by treatments mechanical or chemical such as brushing, combing, dyeing, de- lorations, perms and / or straightening, or even repeated washing.

[0005] The hair is thus damaged by these different factors and can over time become dry, rough, brittle or dull, especially in fragile areas, and especially at the tips.

[0006] Thus, to remedy these drawbacks, it is usual to resort to ca- pills that implement compositions intended to condition the hair by providing them with satisfactory cosmetic properties, in particular smoothing, shine, softness, suppleness, lightness, a natural feel and good detangling properties.

[0007] — These hair care compositions, intended to be applied regularly on the hair, can be, for example, conditioners, masks or serums, and can come in the form of gels, hair lotions and more or less thick care creams.

[0008] It is particularly known to use compositions in the form of oily serums, containing combinations of silicone or non-silicone oils.

[0009] = However, such compositions still too often lead to excessive lubrication important keratin fibers, which results in a greasy or even sticky feel these, and a heavy, loaded visual aspect.

[0010] = In addition, compositions containing non-silicone oils, once applied on the hair, often lead to unpleasant effects to the touch, in particular, hair tends to be coarse and / or "squeaky" (i.e. produce an unpleasant sound effect) especially when rubbing the hair to each other while sliding your fingers along the hair from root to tip. The present invention aims to provide compositions which do not have the drawbacks mentioned above, and which are capable of conditioning keratin fibers in a lasting manner, in particular by giving them good cosmetic properties. The invention also aims to provide hair care compositions which provide coating to the hair, particularly to very sensitized and damaged hair, without weighing it down or making it greasy. This aim is achieved by the present invention which in particular relates to a cosmetic composition comprising: 1) one or more cationic surfactants, 11) one or more fatty alcohols, iii) one or more glycerol esters, (iv) one or more silicones having a viscosity at 25°C greater than or equal to 200,000 mm? / 5s, (v) one or more silicones having a viscosity at 25°C of less than 200,000 mm° / s. The composition comprising the particular combination of the ingredients defined above makes it possible in particular to bring body, strength and discipline to the keratin fibers, and to provide them with a restorative and protective coating. It is particularly effective for the care of very sensitized and / or damaged fibers. The composition according to the invention makes it possible to provide good cosmetic properties to keratin fibers, in particular to hair, in particular in terms of detangling, smoothness to the touch and visually, softness, shine, individualization, discipline and control of frizz. In addition, the composition according to the invention has good usage qualities and does not require the application of a large quantity of composition. It is easy to apply and distribute on the keratin fibers. It has a pleasant texture. It is very easy to remove, by simply rinsing the keratin fibers, without leaving a greasy feel or appearance. The fibers are light, easy to style and shape, not loaded or sticky. The invention also relates to a method for the cosmetic treatment of human keratin fibers such as hair, comprising the application to said keratin fibers of a composition as defined above. Another subject of the present invention relates to the use of the composition as defined above for the care and / or conditioning of keratin fibers, in particular human keratin fibers such as hair. Other objects, features, aspects and advantages of the invention will become apparent even more clearly when reading the description and examples. In this description, and unless otherwise indicated: - the expression “at least one” is equivalent to the expression “one or more” and may be substituted for it; - the expression “between” is equivalent to the expression “ranging from” and can be substituted for it, and implies that the limits are included; - by “keratin fibers” according to the present application, we mean human keratin fibers, and more particularly hair. In all that follows, silicone is used, in accordance with general acceptance, to mean all organosilicon polymers or oligomers with a linear or cyclic, branched or crosslinked structure, of variable molecular weight, obtained by polymerization and / or by polycondensation of suitably functionalized silanes, and consisting essentially of a repetition of main units in which the silicon atoms are linked together by oxygen atoms (siloxane bond -Si-O-Si-), optionally substituted hydrocarbon groups, being directly linked via a carbon atom on said silicon atoms. The most common hydrocarbon groups are alkyl groups, in particular C, -Cy0, and in particular methyl, fluoroalkyl groups whose alkyl part is C, -Cy0, aryl groups such as in particular phenyl groups. As is known per se, the viscosity of silicones, which is the kinematic viscosity, is measured at 25°C and at atmospheric pressure (1 atm, 1, 013.105 Pa) according to the ASTM 445 Appendix C standard. The weight-average molecular masses of silicones can be measured by Gel Permeation Chromatography (GPC) at room temperature (25°C) in polystyrene equivalent. The columns used are styragel y columns. The eluent is THF, the flow rate is 1 ml / min. 200 μl of a 0.5% by weight solution of silicone in THF are injected. Detection is done by refractometry and UVmetry. 1) Cationic surfactants The cosmetic composition according to the present invention comprises one or more cationic surfactants i).

The composition can be used on damp or dry hair, in rinsed or unrinsed mode, and preferably in unrinsed mode (i.e. the keratin fibers are not rinsed after application of the composition).
