This invention relates to a composition, in particular cosmetic, containing glycerin, and a method for washing or cleaning keratin materials implementing said composition.

It is well known in the field of cosmetics to use cleaning compositions that can be foaming. Many publications describe various types of compositions. Most of these cleaning compositions are aqueous compositions in the form of gel or emulsion comprising foaming cleaning surfactants.

Compositions according to prior art have a scope for further enhancement, in particular by supplying new innovative compositions.

As such this invention has for purpose to provide a new composition, in particular cosmetic, cleaning that can be used for the cleaning of keratin materials, in particular the skin, with the composition having an attractive appearance for the consumer and being applied to the skin with an original application method.

The inventors have discovered that a composition comprising a high glycerin content, a particular surfactant and a particular polymer such as described hereinafter has the appearance of an original and attractive flowing liquid honey for the consumer who has the impression of using a natural product.

During the application on the unmoistened dry skin, the composition of the invention surprisingly produces a heating and the initial deposit is transformed into milk during the massage of the composition on the skin with the fingers. After the massage and by applying water to the treated skin, the deposited composition then forms a foam that as such confers good cleaning of the skin. Advantageously, the composition according to the invention is eliminated easily by rinsing with water.

The composition as such forms a heating cleaning product during its application on the skin that is transformed during the application thereof on the skin

The composition makes it possible to clean the skin gently, without drying the skin or generate tautness of the skin. The heating effect of the composition causes a dilatation of the pores of the skin and as such allows for a deep cleaning of the skin.

The composition can furthermore be used as a shampoo for washing hair. In this case, the composition is preferably applied to wet hair.

The invention particularly relates to a composition, in particular a cosmetic composition, comprising:

- from 50 to 80% glycerin;

- at least one surfactant chosen from anionic surfactants, betaine amphoteric surfactants, or any mixture thereof; - at least one copolymer of (meth)acrylamide and salt of di alkyl(d-C ₄ )- diallylammonium and/or (meth)acrylic acid; and

According to an aspect, the invention relates to a method of cosmetic treatment, and more particularly for cleaning or washing, of the skin comprising:

the application on the skin, preferably on unhumidified skin, of a composition according to the invention;

then the massaging, in particular with the fingers, of the composition applied.

Advantageously, the method further comprises, after the step of massaging, the application of water in order to form a foam with the composition applied to the skin, then a step of rinsing.

According to an embodiment, the method further comprises the cleaning of the skin with water in order to remove the composition.

In general, the method of cosmetic treatment, and more particularly for cleaning or washing, of the skin comprises in a first step the application on the skin, preferably on unhumidified skin, of a composition according to the invention; in a second step the massaging, in particular with the fingers, of the composition applied; in a third step the cleaning of the skin with water in order to remove the composition. According to a particular embodiment, the composition according to the invention is transparent and applied to a skin, for example the face, that is dry (unhumidified). By massaging the composition deposited on the skin with the fingers, the initially transparent deposit whitens and takes on the aspect of a milk also procuring a heating effect on the skin. An aqueous solution can then be applied, as for example water on the face, which forms a foam, for example white. The foam has for advantage to clean the skin well. It is then possible to rinse with an aqueous solution, for example water, in order to remove all of the composition applied from the skin. Advantageously after these operations, the skin is cleaned and hydrated well.

According to an alternative, the composition according to the invention is applied to hair.

According to an aspect, the invention relates to a method of cosmetic treatment, and more particularly for cleaning or washing, of hair comprising:

the application on the hair, of a composition according to the invention;

then the massaging, in particular with the fingers, of the composition applied.

Advantageously, the method further comprises, after the step of massaging, the application of water in order to form a foam with the composition applied to the hair, then a step of rinsing.

The composition can be applied on dry hair (unhumidified): the product applied as such forms a protective and hydrating mask for the hair. The composition can also be applied on wet hair.
