Abstract

The present invention relates to a composition preferably for topical application in the form of a water-in-oil emulsion containing at least one emulsifying silicone elastomer and at least one semi-crystalline polymer. The invention also relates to the use of the composition according to the invention for skincare, and in particular for nourishing the skin, preventing transepidermal water loss and protecting the skin.

Description

technical field [0001] The present invention relates to a cosmetic composition in the form of a water-in-oil (W / O) emulsion comprising a substantial amount of an aqueous phase, an oxyalkylenated or glycerylated elastomeric organopolysiloxane, and a semicrystalline polymer. The invention also relates to the use of this composition, especially as a skin care product. Background technique [0002] In the field of cosmetology, emulsions of the water-in-oil (W / O) type are considered to be effective in skin care because they include a continuous oil phase and thus have the potential to form a lipid film on the skin surface, preventing transepidermal water loss, and Protects the skin from external aggressions. These emulsions are especially suitable for protecting and moisturizing the skin, especially for dry skin types. However, W / O emulsifiers are often criticized for being too greasy and viscous, and for having poor stability. Usually, it does not keep fresh and is often too ...
