Abstract
The powdery bleaching composition has improved storage stability and contains from 25 to 70 percent by weight of at least one solid per-compound as effective bleaching agent and from about 0.1 to about 20 percent by weight of at least one cross-linked silicone elastomer. The at least one cross-linked silicone elastomer is made by cross-linking with an alpha, omega-diene or a vinyl-polysiloxane and preferably is a dimethicone/vinyl-dimethicone crosspolymer or a cyclopentasiloxane and dimethicone crosspolymer. Simple methods of making the powdery cosmetic compositions are also described.
Claims7
A powdery bleaching composition comprising
- from 25 to 70 percent by weight of at least one solid per-compound as effective bleaching agent;
- and
- from about 0.01 to 50 percent by weight of at least one silicone elastomer;
- wherein said at least one silicone elastomer is selected from the group consisting of dimethicone/vinyldimethicone crosspolymer and cyclopenta-siloxane and dimethicone crosspolymer.
A powdery bleaching composition comprising
- from 25 to 70 percent by weight of at least one solid per-compound as effective bleaching agent;
- and
- from about 0.1 to about 20 percent by weight of at least one cross-linked silicone elastomer;
- wherein said at least one cross-linked silicone elastomer is made by crosslinking at least one silicone elastomer with a vinylpolysiloxane or an alpha, omega-diene in the presence of a catalyst and in a linear or cyclic polysiloxane solvent.
