Claims Analysis
Total Claims: 10
Claim 1

A stick-type cosmetic comprising gypsum and a pearlescent pigment composition; said pigment composition comprising at least one coated pigment and including water to the amount of at least 20 wt.% of said pigment composition, said pigment being selected from the group consisting of titanium dioxide-coated mica, colored titanium dioxide-coated mica, and colored bismuth oxychloride, coated on the surfaces thereof with a water-repellant coating of a metallic soap of the formula- (RCOO).sub.n M wherein R is selected from straight chain, branched chain, saturated and unsaturated aliphatic hydrocarbon groups having more than 6 carbon atoms, M is selected from aluminum and zinc and n is the valance of the metal, said surface coating being prepared by reacting in an aqueous medium an alkaline salt of an aliphatic acid radical (RCOO) - with a mineral acid metal salt where said metal is M as defined above in a theoretical equivalent ratio of 1:4 to 1:10 and in an amount to cause said water-repellent soap to form and coat the surfaces of said pigment and wherein the wt. ratio of said pigment to said metallic soap being from 1:0.01 to 1:0.1.
Claim 2
Dependent Claim
187 words
A stick-type cosmetic comprising gypsum and a pearlescent pigment composition; said pigment composition comprising at least one coated pigment and including water to the amount of at least 20 wt.% of said pigment composition, said pigment being selected from the group consisting of titanium dioxide-coated mica, colored titanium dioxide-coated mica, and colored bismuth oxychloride, coated on the surfaces thereof with a water-repellant coating of a metallic soap of the formula- (RCOO).sub.n M wherein R is selected from straight chain, branched chain, saturated and unsaturated aliphatic hydrocarbon groups having more than 6 carbon atoms, M is selected from aluminum and zinc and n is the valance of the metal, said surface coating being prepared by reacting in an aqueous medium an alkaline salt of an aliphatic acid radical (RCOO) - with a mineral acid metal salt where said metal is M as defined above in a theoretical equivalent ratio of 1:4 to 1:10 and in an amount to cause said water-repellent soap to form and coat the surfaces of said pigment and wherein the wt. ratio of said pigment to said metallic soap being from 1:0.01 to 1:0.1.
