Claim 1
Independent Claim
336 words
An anhydrous homogeneous single-phase cosmetic stick, cake or cream composition comprising: (a) 2 to 50 wt. % of dimethylpolysiloxane having the formula ##STR5## wherein the Y substituents are both --CH 3 or both --OH, and wherein the degree of polymerization d is sufficient to impart to the dimethylpolysiloxane a viscosity of 0.65 to 10 6 centistokes at 25° C.; (b) 2 to 50 wt. % of an organosilane having the formula RSi(CH 3 ) 3 or an oragano-polysiloxane having the formula ##STR6## or mixtures thereof, wherein R is alkyl having 1 to 30 carbon atoms, or an aryl substituent which is phenyl or a phenyl ring connected to the Si by an alkylene bridge up to 3 carbons long or by a vinyl group; R 1 and R 3 are independently alkyl having 1 to 30 carbon atoms, or an aryl substituent which is phenyl or a phenyl ring connected to the Si by an alkylene bridge up to 3 carbons long or by a vinyl group; R 2 is alkyl having 2 to 30 carbon atoms, an aryl substituent which is phenyl or a phenyl ring connected to the Si by an alkylene bridge up to 3 carbons long or by a vinyl group, or trimethylsiloxy; R 4 is alkyl having 2 to 30 carbon atoms, or an aryl substituent which is phenyl or a phenyl ring connected to the Si by an alkylene bridge up to 3 carbons long or by a vinyl group; n is 1 to 100; m is 0 to 100; and (n plus m) is 1 to 100; X is alkyl or alkyloxy wherein the alkyl group contains 1 to 30 carbon atoms; and (c) 4 30 wt. % of a cosmetically acceptable wax which does not form a homogeneous single-phase mixture with component (a); provided that there is a sufficient amount of component (b) present that the product formed by cooling to 25° C. a molten, stirred mixture of components (a), (b) and (c) is a single homogeneous phase.
