Patent Images
1. A slurry powder cosmetic composition in the form of an evaporation residue of a slurry mixture comprising:
- particulates precoated with a pre-mixed binder composition that contains at least one nonpolar oil selected from the group consisting of dimethicone, C2-30 fatty acid esters, paraffinic hydrocarbons and mixtures thereof;
at least one synthetic wax having a melting point of from about 30°
C. to about 100°
C.; and
at least one film former selected from the group consisting of trimethylsiloxy silicate, dimethicone silylate and mixture thereof;
a silicone gel composition comprising an organosiloxane elastomer solvated or dispersed in a nonpolar oil; and
an alcohol based composition;
wherein the binder composition comprises 5 to 75% by weight of the final composition.

14. A method for making a slurry powder composition comprising:
-
(a) combining at least one nonpolar oil selected from the group consisting of dimethicone, C2-30 fatty acid esters, paraffinic hydrocarbons and mixtures thereof, at least one synthetic wax having a melting point of from about 30°
C. to about 100°
C., and at least one film former selected from the group consisting of trimethylsiloxy silicate, dimethicone silylate and mixture thereof to form a binder composition,(b) coating particulates with the binder composition of (a), (c) adding a silicone gel composition comprising an organosiloxane elastomer solvated or dispersed in a nonpolar oil to the mixture of (b), (d) adding an alcohol based composition to the mixture of (c), (e) subjecting the mixture of (d) to slurrying., (f) evaporating the slurrying mixture of (e), to yield a slurry powder composition which contains 5 to 75% by the weight of the total formulation of the binder composition. - View Dependent Claims (15, 16)
