Description

Title of the invention: Cosmetic composition comprising specific cationic guars and carboxylic anionic surfactants, and cosmetic processing method

[0001] The present invention relates to a cosmetic composition, in particular for hair cleansing, comprising particular anionic surfactants and particular cationic polymers, as well as a cosmetic treatment process, in particular for hair, implementing said composition.

[0002] Hair is sensitive to many types of aggression and can be weakened and damaged to varying degrees by the external environment, in particular by the action of atmospheric agents such as light, air pollution and weathering, as well as by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perming and / or straightening, or even repeated washing.

[0003] The properties of damaged hair are then degraded and various manifestations of damage can be observed, such as difficulties in detangling and styling the hair, lack of softness of the hair, hair which can eventually become dry, brittle or dull, especially in fragile areas, and more particularly at the tips.

[0004] To remedy these drawbacks, and in particular to repair damaged hair, it is common practice to use hair cosmetic compositions designed to condition the hair by providing it with satisfactory cosmetic properties. Current compositions generally aim to reduce surface defects of the hair, notably through the deposition of conditioning agents, such as silicones or cationic polymers. The effects obtained generally rely on the use of high levels of silicones, which can, however, have the disadvantage of weighing down the hair or causing it to lose its lightness.

[0005] Furthermore, although there are numerous hair repair formulas, they generally do not provide hair with entirely satisfactory and lasting cosmetic properties, particularly when the hair is very fragile, highly sensitized, or severely damaged. Thus, it has been observed that for the most damaged hair, the level of care may prove insufficient; in particular, the smoothness of the hair and its ease of detangling can still be improved.

[0006] The invention therefore aims to provide a cosmetic composition, particularly for hair care, specifically for cleansing and / or conditioning hair, which solves the problems mentioned above, and in particular will provide a high level of care and conditioning, especially for the most damaged hair.

[0007] The present invention relates to a cosmetic composition, particularly for hair, comprising:

[0008] - one or more cationic guars with INCI name: GUAR HYDROXYPROPYLTRIMONIUM CHLORIDE and having a dynamic viscosity between 500 and 1500 mPa.s, measured at a concentration of 1% by weight in water at 25°C and atmospheric pressure, and

[0009] - one or more anionic surfactants selected from alkyl(amido)ether acids polyoxyalkylated carboxylic acids and their salts.

[0010] It has been observed that hair treated with the compositions according to the invention exhibits good cosmetic properties: it is particularly shiny, light, smooth to the touch, supple, easy to detangle and more manageable.

[0011] The compositions according to the invention also have good performance qualities: they allow for the rapid generation of abundant, rich, creamy and pleasant-to-the-touch foam.

[0012] Furthermore, it has been observed that it is possible to obtain compositions presenting a new visual aspect, namely compositions that are particularly clear, or even transparent.

[0013] Thus, the compositions according to the invention can advantageously be clear, even transparent; in particular, they can have a turbidity value less than or equal to 50 NTU, preferably less than or equal to 20 NTU, even better less than or equal to 10 NTU, preferably less than or equal to 5 NTU. The turbidity can be measured at 25°C, 1 atm, using a HACH Model 2100 P turbidimeter.

[0014] In this description, and unless otherwise indicated:

[0015] - 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 limits are included. Cationic guar

[0016] The composition according to the invention comprises one or more particular cationic guars as defined below.

[0017] This or these cationic guars are hydroxypropyltrimonium guar chlorides; they have the INCI name: GUAR HYDROXYPROPYLTRIMONIUM CHLORIDE.

[0018] They also exhibit a dynamic viscosity between 500 and 1500 mPa.s, measured at a concentration of 1% by weight in water, at 25°C and at atmospheric pressure (1.013.105 Pa).

[0019] Dynamic viscosity can in particular be measured using a rheometer such as the Brookfield RVT viscometer, with a spindle 2, at a rotation speed of 20 revolutions / min, the measurement being carried out after 30 seconds of rotation, at 25°C and atmospheric pressure, and at a concentration of 1% by weight in water.

[0020] By way of example, a cationic guar having a dynamic viscosity between 500 and 1500 mPa.s (at 25°C and atmospheric pressure), usable in the composition according to the invention, is that referenced under the number CAS 65497-29-2; one can in particular mention the commercial product available under the name Natemal® Care Clear SGI from the company SYENSQO.

[0021] Preferably, the composition according to the invention comprises the said cationic guar(s), of INCI name: GUAR HYDROXYPROPYLTRIMONIUM CHLORIDE and having a dynamic viscosity of between 500 and 1500 mPa.s, in a total content of 0.01 to 8% by weight, better of 0.05% to 5% by weight, even better of 0.1% to 3% by weight, preferably of 0.2% to 1% by weight, relative to the total weight of the composition.
