Abstract

The subject of the present invention is a foaming composition comprising, in a physiologically acceptable aqueous medium, Aloe vera in a content of at least 0.03% by weight, relative to the total weight of the composition, and at least one surfactant chosen from isethionic acid derivatives and salts thereof.

Description

Cosmetic composition comprising Aloe vera and an isethionic acid derivative

The present invention relates to a foaming cosmetic composition comprising Aloe vera and an isethionic acid derivative, and also to the use of said composition, in particular in the cosmetics field as a product for cleansing or removing makeup from keratin materials such as the skin, keratin fibres (eyelashes and hair) or the scalp and also for treating oily skin and/or disinfecting the skin and/or the scalp.

The commercially available foaming cleansing products are generally either foaming products with soaps which have the advantage of giving a creamy foam but which can cause taughtness due to them having too much detergence, or foaming products without soaps which generally comprise anionic surfactants such as sulphate derivatives, for instance sodium laureth sulphate, and/or thickeners of synthetic origin, such as acrylic polymers.

Although these surfactants are very effective in terms of foam and detergence, they can have an irritant potential at a high content, in particular in individuals with sensitive or reactive skin.

Moreover, these compositions must be thickened in order to have a consistency suitable for their use, in particular by using salts, thickeners of synthetic origin or gums, but the increase in viscosity can have a negative impact on the qualities of the foam (in particular in terms of foam initiation and amount of foam).

It is therefore sought to obtain foaming compositions which exhibit good innocuousness with respect to keratin materials, while nevertheless at the same time having the required properties for foaming products, namely a suitable viscosity and rapid conversion to foam, an abundant foam and good rinsing.

The Applicant has discovered that the use of an isethionic acid-derived surfactant, in combination with Aloe vera, makes it possible to achieve these objectives.

Thus, the subject of the present application is a foaming cosmetic composition comprising, in a physiologically acceptable aqueous medium, Aloe vera in a content of at least 0.03% by weight relative to the total weight of the composition and at least one surfactant chosen from isethionic acid derivatives and salts thereof. The term "physiologically acceptable medium" is herein intended to mean a medium compatible with keratin materials such as the skin, the mucous membranes, the scalp, the eyes and/or keratin fibres such as the eyelashes or the hair. The use of isethionic acid-derived surfactants and of Aloe vera which has thickening properties makes it possible to obtain compositions having a reduced, or even zero, content of sulphate-derived detergent surfactants and having a suitable consistency and good foaming properties.

It has also been noted that Aloe vera in combination with the isethionic acid derivative makes it possible to obtain a significant increase in the viscosity of the compositions, in particular a viscosity greater than that obtained when Aloe vera is combined with a sulphate-derived surfactant.

The term "sulphate or sulphate-derived surfactant" is intended to mean a compound comprising at least one sulphate functional group (-OS0₃H or -OS0₃ ).

The compositions of the invention are foaming cleansing compositions that can be rinsed off; they are in the form of a translucent aqueous fluid which is stable over time. They have good cosmetic properties, i.e. an even and pleasant texture on application, a sufficient foam and good innocuousness.

The composition according to the invention may in particular constitute a composition for cleansing or removing makeup from keratin materials.

Aloe vera

The Aloe vera may be at 100% of active material, and it may be in the form of a powder or in the form of an extract. The term "Aloe vera extract" is intended to mean all types of substances and/or molecules obtained by aqueous and/or alcoholic extraction. According to one preferred embodiment of the invention, the Aloe vera is in the form of a powder. Preferably, the Aloe vera (CTFA name: ALOE BARBADENSIS) is in the form of a powder at 100% of active material.

The following commercial references can, for example, be used:

- ALOE CON UP 200 CT 82 (Florida Food)

- ALOE VERA FREEZE DRIED POWDER 200: 1 (MA 170) (Mexi Aloe Lab)

- ALOE-CON WG 200 (Florida Food)

- ACTIVERA 1 200 C (AV105702-00) (Active organics) - 4044 PE ALOE VERA 1 : 199 (Bio-Botanica)

- ALOE VERA GEL DECOLORIZED 1X (TERRY)

- ALOE VERA GEL (1X-CG) / CODE 03-2312 (CONCENTRATED ALOE

CORPORATION).

The amount of Aloe vera dry matter in the composition of the invention should be sufficient to obtain the desired viscosity, i.e. at least 0.03% by weight, preferably at least 0.04% by weight, relative to the total weight of the composition. It can range up to 5% by weight, preferably up to 3% by weight, better still up to 1 % by weight, relative to the total weight of the composition. When the Aloe vera used is in the form of Aloe vera juice, the expression "amount of Aloe vera dry matter or active material" is intended to mean the amount obtained once the juice has been dehydrated.

The isethionic acid derivative or salt may be, for example, chosen from acyl isethionic acids, salts thereof (isethionates) and mixtures thereof, preferably from the salts of acyl isethionic acids of which the hydrocarbon-based chain R1 of the acyl group R1 C=0 is linear or branched and contains from 8 to 30 carbon atoms, preferably from 10 to 22 carbon atoms, and better still from 12 to 18 carbon atoms.

The acyl group may in particular be chosen from lauroyl, myristoyl, palmitoyl, stearoyl, olivoyl, cocoyl and oleoyl groups, and mixtures thereof.

The term "cosmetically acceptable salts" is intended to mean that the hydrogen atom of the acid functional group of the isethionic acid is replaced with an M+ cation, for example chosen from the ions of alkali metals such as Na, Li or K, preferably Na or K, the ions of alkaline-earth metals such as Mg, ammonium groups and mixtures thereof.

Procedure:

For compositions 1 and 2: the Aloe vera (where appropriate), the glycerol, the

preservative and the salicylic acid are mixed in water at 50-55°C and then the Iselux is added with mixing, the mixture is brought back to ambient temperature, then the betaine is added and the pH of the composition is adjusted.

For compositions 3 and 4: the Aloe vera (where appropriate), the sodium laureth sulphate, the glycerol, the preservative and the salicylic acid are mixed in water at AT and then the betaine is added and the pH of the composition is adjusted.

The Ford cup (diameter 6 mm) viscosity of each composition is measured 24 h after production; this method consists in measuring, at a predetermined temperature, the time taken for 90 g of product to flow through an orifice of predetermined diameter. The result is expressed in seconds.

The volume of the sample of composition is at least 150 ml, the product introduced into the cup having a homogeneous and nonaerated appearance.

The sample is thermostatted at 25°C ± 0.5°C before characterization. The following results were obtained:

It is noted that the introduction of Aloe vera into an isethionic acid derivative-based surfactant system enables a greater increase in viscosity than in a system based on sulphate-derived surfactants.
