Claim 1
Independent Claim
117 words
A method of preparing a stable waterproof makeup having a water disperse phase and an oil continuous phase which comprises (A) admixing (a) a cosmetic emulsion oil and (b) a cosmetic pigment and (c) an emulsifier combination comprising (i) a stearate selected from the group consisting of aluminum stearate, calcium stearate and mixtures thereof, and (ii) a polyhydric alcohol ester of a liquid fatty acid having an HLB value less than 5 and selected from the group consisting of polyglycerol (4) monooleate, sorbitan sesquioleate and glycerol monooleate; and (B), while agitating, blending at 90° C.-95° C. therewith (d) water which has been heated to a temperature in the range of about 90° C. to about 95° C.
