FOAMING COSMETIC COMPOSITION; USES FOR
The present invention relates to a foaming composition for topical application, containing a particular surfactant system consisting of at least one partially or totally neutralized fatty acid, an amphoteric non-betaine co-surfactant and a co-surfactant. anionic surfactant of the sulfosuccinate type as well as its use in the cosmetic or dermatological fields, especially as cleaning or makeup removal products for human keratin materials and more particularly for the skin.

The cleaning of the skin is very important for the care of the face. It must be as efficient as possible because the fatty residues such as the excess of sebum, the remains of the cosmetics used daily and the make-up products in particular the waterproof products resistant to the water, accumulate in the folds of skin and can clog the pores of the skin and cause the appearance of pimples.

Several major types of skin cleansing products are known: foaming detergent aqueous lotions and gels, rinse-off anhydrous cleansing oils and gels, and foaming creams.

Rinseable anhydrous oils and gels have a cleaning action thanks to the oils contained in these formulations. These oils allow the solubilization of the fatty residues and the dispersion of the makeup pigments. These products are effective and well tolerated. They have the disadvantage of being heavy, not to foam and not to give a feeling of freshness to the application, which is penalizing from a cosmetic point of view.

In addition, foaming detergent aqueous lotions and gels have a cleaning action thanks to the surfactants which suspend the fatty residues and the pigments of the make-up products. They are effective and pleasant to use because they foam and are easily removed. However, the lotions are generally quite fluid, which makes their handling sometimes delicate, and it is difficult to thicken the gels while keeping good foaming properties.

To obtain good foaming performance while having a thick composition, it has sought to prepare foaming creams.

The term "foaming creams" is intended herein to mean opaque, viscous compositions generally packaged in a tube and generally consisting of an aqueous medium containing a mixture of surfactants such as the salts of fatty acids (soaps) or synthetic surfactants anionic, nonionic, amphoteric and other additives such as, for example, polymers, polyols, fillers.

These creams, especially for cleaning the skin, develop foam when mixed with water. They can be used in two ways: # the first use is to spread the cream in the hands, to apply it on the face or on the body then to massage it in the presence of water to develop the foam directly on the face or the body.

 # the other possible use of this type of product is to develop the foam in the palms of the hands before being applied on the face or the body.

In both cases, the foam is then rinsed.

Of the foaming creams currently available commercially, some produce foams whose qualities are not yet satisfactory especially

<Desc / Clms Page number 2>

 at the fast start of the foam, the foaming power, the creamy appearance of the foam (density).

Other foaming creams are unstable over time and sensitive to temperature variations and transport and storage conditions: they quickly lead to macroscopic demixing, resulting in separation into at least two phases.

However, it is essential that a foam cleaning cream is resistant after several months to temperature changes and transport conditions. Indeed, during its life, the product may be exposed to temperatures that vary according to climate, storage or transport conditions. He may also be shaken during transport. It is also necessary that these foaming creams can be used in hot countries without their transportation and conservation pose a problem.

There remains therefore the need for a foaming cleaning cream that is resistant over time to temperature variations and transport conditions and that does not have the disadvantages listed above.

The Applicant has surprisingly found that the object of the invention can be achieved and a foaming composition in the form of a cream having good stability can be achieved by using a particular surfactant system consisting of at least one acid. partially or totally neutralized fat, an amphoteric non-betaineic co-surfactant and an anionic co-surfactant of the sulfosuccinate type.

It is thus possible to obtain an opaque composition which has very good cosmetic properties (softness, lubricity), has a good spreading at the outlet of the tube, produces a foam which starts quickly, which is creamy, dense and which is eliminated very quickly at rinsing. The composition obtained also has good resistance over time to temperature variations and transport conditions.

Thus, the present application relates to a foaming composition for topical application, containing in a cosmetically acceptable aqueous medium at least one surfactant system comprising: (a) at least one fatty acid or a mixture of fatty acids partially or totally neutralized by a organic or mineral base; (b) at least one amphoteric non-betaineic surfactant; (c) at least one anionic surfactant of the sulfosuccinate type; the weight ratio of the non-betaineic surfactant to the sulphosuccinate surfactant being less than 2.

Another subject of the invention consists in the cosmetic use of the composition as defined above, as cleaners and / or makeup removers of keratin materials.

Another subject of the invention consists in a cosmetic process for cleaning the dirt residues of human keratinous materials, characterized in that the composition of the invention is applied to said keratinous substances in the presence of water. it is massed to form a foam and the formed foam and the soil residues are removed by rinsing with water.

Throughout the description, human keratin materials are understood to mean the skin (body or face including the eyelids and the scalp) and the integuments such as hair, eyelashes and eyebrows.

The creams of Examples 5 to 7 are prepared according to the same procedure as Examples 1 to 4 above. Their viscosity is determined at 25 ° C. by Rheomat RM180 (from Rheometric Scientific) with mobile 4 (TV set), a measurement system 75 and a velocity gradient of 200 s -1 and a rotation time of the mobile phone. 10 minutes.

Sensory Performance: The foam qualities of the compositions of Examples 5, 6 and 7 were evaluated by a panel of 7 people according to the protocol described below: Before any use of the products, the hands are washed with soap and then rinsed thoroughly.

Then the following steps are carried out: - wet hands by passing under running water thermostated at 38 C with a flow rate of 8 l / min, - place 2 g of product in the hollow of one of the hands, - add 3 ml of the same water and work the product for 15 seconds, - evaluate the foam quality criteria of the test, - rinse hands under the same running water,

<Desc / Clms Page number 11>

 The following criteria are evaluated and scored on a scale of 0 to 10.

Starting the foam: the higher the rating, the faster the start.

Quantity: foaming power; the score awarded is all the higher as the product has developed more foam in the hands The feeling of creamy: the score awarded is even higher than the creamy sensation is great.

The mean sensory results for each of the criteria are presented in the following table:
