Abstract

COSMETIC COMPOSITION, COSMETIC TREATMENT PROCESS AND COSMETIC PROCESS FOR CLEANING IMPURITIES RESIDUES. The present invention relates to a cosmetic composition, particularly a hair composition, comprising anionic surfactants, amphoteric surfactants, cationic polysaccharides and unsaturated fatty alcohols present in a content of less than 1% by weight relative to the total weight of the composition. The invention also relates to a cosmetic treatment process for caring for and/or cleaning hair, using said composition.

Description

[0001] The present invention relates to a composition, in particular a cosmetic composition, in particular a hair composition, comprising one or more anionic surfactants, one or more amphoteric surfactants, one or more unsaturated fatty alcohols and one or more cationic polymers. The invention also relates to a cosmetic treatment process using said composition. These compositions are intended more particularly for cleaning and/or conditioning keratin materials, in particular hair.

[0002] It is common practice to use detergent cosmetic compositions, such as shampoos or shower gels, based essentially on surfactants, for washing keratin materials, such as skin and hair. These compositions are generally applied to the keratin materials, which are preferably wet, and the foam generated by massaging or rubbing with the hands or a washing glove makes it possible, after rinsing with water, to remove the various types of impurities initially present in the hair or skin.

[0003] These base compositions have good washing capacity, but their intrinsic cosmetic properties nevertheless remain quite weak, notably due to the fact that the relatively aggressive nature of such a cleaning treatment can, in the long term, give rise to more or less marked damage to the hair fibers, associated in particular with the gradual removal of the fats or proteins contained in or on their surface.

[0004] Thus, in order to improve the cosmetic properties of the above detergent compositions, and more particularly of those which are to be applied to sensitive hair (i.e. hair which is generally damaged or brittle by the action of external atmospheric agents, such as light and bad weather, and/or mechanical or chemical treatments, such as blow-drying, combing, dyeing, bleaching, permanent waving and/or relaxing), it is now common practice to introduce into these compositions additional cosmetic agents known as conditioning agents, which are intended mainly to repair or limit the damaging or undesirable effects caused by the various treatments or attack factors to which keratin materials are more or less repeatedly subjected, particularly keratin fibres and, in particular, hair. These conditioning agents can obviously also improve the cosmetic behaviour of natural hair.

[0005] Thus, it is a known practice to use cationic polymers and/or silicones as conditioning agents in cosmetic detergent compositions, such as shampoos, to give hair satisfactory cosmetic properties, in particular, in terms of shine, softness, lightness, a natural feel and improved detangling.

[0006] Mention may be made, in particular, of document No. FR 2 773 710 which describes aqueous cosmetic compositions comprising anionic and amphoteric surfactants and cationic polysaccharides.

[0007] It was also envisaged to propose compositions with an innovative visual appearance, namely compositions that are particularly clear, or even transparent; however, the introduction of fatty substances, even when liquid, may have an impact on the clarity of the compositions.

[0008] Thus, current compositions for washing and/or conditioning keratin materials still have several disadvantages: the presence of silicone, the environmental profile which is not always ideal, the generally creamy and opaque appearance of the composition associated with the presence of conditioning agents, the onset of foaming and the quality of foam which are still not completely satisfactory, rapid relubrication of the hair accompanied by the straightening capacity.

[0009] Thus there is a real need for clear cosmetic compositions intended for cleaning/washing keratin materials that preferably do not comprise any silicone ("silicone-free"), that have good operating properties, such as good intrinsic washability, while at the same time making it possible to obtain excellent cosmetic properties, in particular in terms of detangling, manageability, control, a soft feel and smoothing of the treated hair.

[0010] The Applicant has surprisingly found that it is possible to formulate detergent and conditioning compositions for keratin materials, which have the desired properties, by combining anionic and amphoteric surfactants with particular cationic polymers and particular fatty alcohols.

[0011] A subject matter of the present invention is thus a cosmetic composition, in particular a hair composition, comprising: - one or more anionic surfactants, - one or more amphoteric surfactants, - one or more cationic polysaccharides and - one or more unsaturated fatty alcohols, in a total content of less than 1% by weight relative to the total weight of the composition.

[0012] The composition according to the invention has good detergent or washing properties, and has good tolerance particularly with regard to the skin, mucous membranes, scalp and eyes, while at the same time resulting in good conditioning of keratin materials.

[0013] The composition according to the invention makes it possible to rapidly obtain an abundant foam of very good quality. The foam is homogeneous and shows good persistence over time. It spreads easily and evenly over keratin materials and is easily rinsed off.

[0014] Furthermore, the composition according to the invention provides good cosmetic properties to keratin materials, particularly to hair, in particular sensitive hair. After rinsing, the hair is easy to detangle, soft, smooth and has a soft touch.

[0015] By means of the invention, it is also possible to obtain a cosmetic composition that is advantageously clear and transparent to translucent, more preferably transparent.

[0016] The term "clear composition" means a composition that can be seen through distinctly with the naked eye.

[0017] The transparency of the composition can be characterized by measuring its transmittance. In the context of the present invention, transmittance measurements are obtained at 25 °C and at atmospheric pressure (1 atm) with a Cary Type 100 UV scanning visible spectrophotometer.

[0018] Preferably, the transmittance of the composition according to the invention, measured at room temperature (25 °C) and atmospheric pressure, is greater than or equal to 80%, preferably greater than or equal to 85%, even more preferably greater than or equal to 90%, or even greater than or equal to 92% and, even better, greater than or equal to 94%; in particular, in the range from 80% to 100%, or even from 85% to 100%, particularly from 90% to 100%, or even from 92% to 98%.

[0019] The composition is particularly suitable for use on fine and/or damaged and/or sensitive hair; the hair is easy to detangle and comb, soft and light, and has a smooth touch.

[0020] The composition according to the invention preferably has a thickened texture, which allows it to be spread on the hair easily while preventing it from running during application, for example to the eyes; it has also been found that the composition according to the invention is particularly stable.

[0021] The viscosity of the composition according to the invention can be evaluated by determining, at a temperature of 25 °C, the flow time of a quantity of product (for example 90 g of poured product) through a calibrated orifice using a Ford cup viscometer equipped with a Ford cup with an orifice diameter of 8 mm (cF8).

[0022] Preferably, the flow time of the composition according to the invention is greater than or equal to 20 seconds, in particular greater than or equal to 30 seconds, even better greater than or equal to 40 seconds; in particular between 20 and 200 seconds, even better between 30 and 150 seconds, or even between 40 and 100 seconds, even better between 50 and 90 seconds.

[0023] In the present description, the expression “at least one” is equivalent to the expression “one or more” and can be replaced by it.

[0024] In the present description, the expression "between" is equivalent to the expression "in the range of" and can be replaced by it; in these expressions, the limits are considered as inclusive.
