Abstract
The invention relates to a cosmetic composition in the form of a compact powder comprising a fatty phase and a pulverulent phase, said pulverulent phase comprising a first incompactible filler and at least a second filler which may be compactible or incompactible, these two fillers being of different types. The composition preferably has an internal porosity of greater than 2 m.sup.2 /g. The composition is obtained by preparing an oil-in-water type emulsion of the fatty phase in an aqueous phase, dispersing the pulverulent phase in the emulsion, casting the dispersion obtained in a mould, and freeze drying the dispersion.

A composition in the form of a compact powder comprising a fatty phase and a pulverulent phase, said pulverulent phase comprising a first incompactible filler and at least one second filler, which may be compactible or incompactible, said first and said second fillers being inorganic lamellar fillers, organic lamellar fillers, inorganic spherical fillers, or organic spherical fillers, said first and said second fillers being different types, wherein said composition comprises about 2-10% of incompactible fillers relative to the total weight of the composition when said incompactible fillers have a density less than 0.1 g/cm.sup.3, and from about 2-40% incompactible fillers relative to the total weight of the composition when said incompactible fillers have a density of 0.1-0.5 g/cm.sup.3, and from about 30-90% incompactible fillers relative to the total weight of the composition when said incompactible fillers have a density greater than 0.5 g/cm.sup.3, wherein said composition is prepared by a process comprising the steps of:
- preparing an oil-in-water emulsion of said fatty phase in an aqueous phase;
- dispersing said pulverulent phase in said emulsion;
- casting said dispersion obtained in a mold;
- and
- freeze drying said dispersion.
