  • Publication number: 20050186235
    Abstract: The present disclosure provides compact powder form cosmetic compositions for making up and/or caring for the skin, including the face, comprising a pulverulent phase and a fatty phase comprising at least one solid fatty phase, wherein the solid fatty phase is present in an amount such that the compact powder has a cohesion corresponding to a loss of mass, evaluated by the drop test, of less than 12% by weight, and the pulverulent phase is such that when it is used in a proportion of 91.2% by weight as a mixture with 8.8% of a reference liquid binder described in Example 1 and when the whole is compacted at a pressure of 2×107 Pa, it results in a compact whose cohesion corresponds to a loss of mass, evaluated by the drop test, of greater than 12% by weight and/or a compact that does not erode homogeneously.
