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.
