Abstract: Solid cosmetic composition in the form of a molded powder cake includes a particulate charge containing hollow microspheres having one or more open or closed cavities. The weight proportion of the hollow microspheres ranges from 0.1 to 50 percent relative to the total weight of the composition. A process for the preparation of the composition and the use of such a particulate charge, dispersed in a non-aqueous liquid vehicle, for the preparation of a fluid paste intended for the preparation of such a solid cosmetic composition is also disclosed.

Abstract: Process for the manufacture of a solid cosmetic composition using plaster of Paris, in which:a pulverulent mixture (P) consisting of:1) calcium sulphate hemihydrate (CaSO.sub.4.1/2 H.sub.2 O) in powder form,2) a hydrophobic fraction (OF) comprising at least one fatty substance and/or at least one pulverulent substance treated by coating or chemical grafting so as to give it hydrophobic properties,3) a hydrophilic fraction (IF) in powder form, is prepared, the weight proportion IF/OF being between 0.08 and 7.5;an aqueous phase (AP) in liquid form is prepared;the pulverulent mixture (P) and the aqueous phase (AP) are headed in a weight proportion P/AP of between 0.2 and 2, so as to obtain a pourable mixture;the pourable mixture is run into a mould;it is left to harden by hydration of the calcium sulphate hemihydrate to calcium sulphate dihydrate (CaSO.sub.4.2H.sub.2 O), and the product is removed from the mould.

Abstract: A cosmetic composition for skin consisting of an anhydrous powder and mainly including a solid particulate phase mixed with a fatty binder containing a silicone mixture which consists of (a) at least one silicone oil, (b) at least one silicone wax, (c) at least one silicone resin, (d) optionally at least one silicon gum, and (e) optionally at least one phenyldimethicone; wherein components (a), (b), (c), (d) and (e) are present in the binder in concentrations of 12-98.9%, 1-60%, 0.1-25%, 0-3% and 0-20% by weight respectively in relation to the overall weight of the silicone mixture. The composition may be used as face make-up, as eye shadow or as a make-up foundation or powder.
