Title:
USE OF DEFORMABLE HOLLOW PARTICLE FOR PREVENTING TITANIUM OXIDE COLOR ELEMENT-CONTAINING COSMETICS AND/OR DERMATOLOGICAL COMPOSITION FROM LIGHT BLUEING AND/OR WHITENING
Document Type and Number:
Japanese Patent JPH0925215
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To obtain a cosmetic and a composition for dermatological use suppressed and freed from photobluing and whitening phenomena caused by a composition containing a titanium oxide coloring matter by introducing deformable hollow particles having a specific density and a specified particle diameter into the composition. SOLUTION: Deformable hollow particles, having 1-250μm particle diameter and comprising an expanded copolymer of vinylidene chloride, acrylonitrile and methyl (meth)acrylate are used. The hollow particles have especially <100μm, above all, preferably 10-60μm particle diameter. Furtermore, the hollow particles have preferably 15-200kg/m<3> , especially preferably 40-100kg/m<3> density. The hollow particles are contained in an amount of preferably 0.1-10wt.%, especially preferably 0.3-5wt.% based on the total weight of the composition. The titanium oxide is contained in an amount of at least 5wt.%, especially at least 10wt.%, above all, at least 15wt.% based on the total weight of the composition.
