LOOSE POWDERS TURNING INTO LIQUIDS UNDER COSMETIC APPLICATION

摘要

Claimed is a method for the preparation of cosmetic compositions having the texture of a cream when applied to the skin. The composition comprises a liquid phase (A), a powder containing a gelling agent (B), and optionally, (C) an active cosmetic ingredient. The liquid phase is encapsulated or immobilised in a solid carrier and the powder phase includes starch modified by carboxymethyl groups. The solid carrier consists of mineral particles with a hydrophobic surface such as titanium dioxide treated with a silane group, a fluorinated group or a combination thereof. A variation is described where the gelling agent is made up in whole or in part of particles of modified mica and the mineral particles comprise metallic oxide particles with hpophobic groups grafted on their surface.
