Description

<Desc / Clms Page number 1>

The present application relates to a composition comprising an aqueous phase comprising particles of a silicone block copolymer, an organic filler and a mineral filler, and to the use of said composition in the cosmetic and dermatological fields, in particular for the care, treatment, cleansing and / or makeup of the skin of the body or face, hair and / or lips.

To improve the lightness of the cosmetic compositions, it is known to add mineral or organic fillers. These fillers provide lightness and softness, but they give a dry effect when applied to the skin. They also have the disadvantage of giving the impression of a lack of hydration. In addition, to obtain more softness, it is necessary to put a quantity such that one is then faced with linting problems during application to the skin.

douceur et de la consistance. Toutefois, te toucher final lors de l'application sur la peau reste sec et peut même être encore plus sec. En outre, ces élastomères huileux ont tendance à alourdir la composition, c'est-à-dire que la composition laisse un effet filmogène assez désagréable. To remedy the disadvantage of a dry touch, it has been envisaged to add oils. However, when the compositions contain too much oil, they leave the skin oily and shiny, which is unacceptable for the user. It is also possible to overcome the dryness of the touch by adding cross-linked silicone elastomers in oily dispersion which provide

sweetness and consistency. However, the final touch when applying to the skin remains dry and may even be even drier. In addition, these oily elastomers tend to weigh down the composition, that is to say that the composition leaves a rather unpleasant film-forming effect.

The object of the invention is to be able to produce compositions containing fillers having good cosmetic properties without having the disadvantages of the prior art.

The Applicant has unexpectedly discovered that the fact of associating block silicone copolymer particles with both organic fillers and mineral fillers made it possible to obtain a composition having high cosmetic qualities, that is to say both soft, soft, elastic and moreover surprisingly having emollient and moisturizing properties. To obtain the desired qualities, it is necessary to have the three kinds of particles.

Thus, the present invention relates to a composition comprising, in a physiologically acceptable medium, at least one aqueous phase comprising block silicone copolymer particles, at least one organic filler and at least one mineral filler.

The composition of the invention being intended in particular for a topical application comprises a physiologically acceptable medium, that is to say a medium compatible with all keratin materials such as skin, nails, mucous membranes and hair or any other skin area of the body. It may constitute in particular a cosmetic or dermatological composition.

Procedure: Phase A is prepared by heating the constituents of this phase to 60 C. Phase B is prepared by heating the mixture of water and water.

glycerin at 65 ° C., by preserving the preservatives and dye, adding the Hostacerin AMPS and maintaining the stirring until gelation. The emulsion is prepared by pouring phase A at 60 ° C. in phase B at 650 ° C. with stirring, then Simulgel EG is added; homogenized and cooled to 30 C. The phase C is then added with stirring.

An emulsion fluid is obtained which has an effect of surprising softness and comfort and which can be used morning and / or evening. This fluid was tested on a panel of 30 women who found it very soft on application, light and comfortable, leaving the skin very soft.

A very gentle moisturizing compact product is obtained. This product, because of its nomadic product presentation (that is to say that you can take with you) can be used during the day when the skin feels the need. It can be applied to the finger or the sponge.

Procedure: Phases A and B are mixed, and then pre-mixed phase C is added dropwise. The assembly is then milled in a pin mill, then sieved to be deagglomerated due to the tendency of the powders to agglomerate. This powder is then compacted in cups.

We obtain a very soft compact powder that is applied to the sponge or brush directly on the skin or on a foundation to obtain a velvety makeup.
