Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
143 words
A method for manufacturing a solid stick of powder for cosmetic and toilet use comprising the steps of, blending (1) one or more particulate materials selected from the group consisting of talc, kaolin, calcium carbonate, magnesium carbonate, starch, zinc white, titanium dioxide, metallic soap, silica; particulate resin, hydrocarbons, fats and oils, waxes, fatty acids, lower and higher alcohols, esters, and phospholipids; (2) one or more ingredients consisting of surface active agents, perfumes, pigments and preservatives and (3) as a binding aid, one or more ingredients selected from the group consisting of particulate polyethylene, zinc stearate, corn starch, silicone oil, lanolin and kaolin, and mixing with agitation at a temperature of from 90° C. to 160° C.; pulverizing the resultant mixture, and compressing said pulverized material at an impact pressure of about 3.0 kg/cm 2 to 8.0 kg/cm 2 to form a solid stick.
