Abstract
Abstract An improved dry pressed powder composition containing, by weight, about 1 to 10% a metal stearate, e.g. zinc stearate, about 1 to 10% alkaline metal carbonate, e.g. magnesium carbonate, about 10 to 50% of a naturally or synthetically derived cellulose or derivative thereof; and about 10 to 60% of aluminum potassium silicate; and a cosmetically effective amount of a cosmetically active ingredient, e.g. about 15 to 30% of aluminum chlorohydrate antiperspirant. The ingredients are blended together in a dry form and pressed into a stick-type form.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
140 words
In an improved dry pressed powder stick composition consisting essentially of, by weight: (a) about 1 to 10% of a metal stearate; (b) about 1 to 10% of an alkaline metal carbonate; (c) about 10% to 50% of a naturally or synthetically derived cellulose or derivative thereof; (d) about 0.05% up to 50% of cosmetically active ingredient which is stable in the composition, wherein the improvement comprises about 10% to 60% of aluminum potassium silicate, said dry pressed powder stick composition formed by mixing all of the above ingredients in a dry blend to form a homogeneous mixture, loading the mixture into a mold, and then applying pressures from about 100 psi to 3000 psi to the mixture in the mold at a temperature from 20° C. to 80° C. for a time sufficient to achieve the pressed stick composition.
