Abstract
The invention discloses an aqueous slurry of globular particles of a silicone-based composite elastomer consisting of titanium dioxide particles and a crosslinked silicone elastomer as the matrix for the titanium dioxide particles. The aqueous dispersion comprises from 10 to 60% of the globular elastomer particles of 0.1 to 100 &mgr;m diameter, from 0.1 to 30% by weight of a surfactant which is preferably an anionic surfactant such as a salt of a dialkyl sulfosuccinate and the balance of water. The aqueous dispersion of the globular elastomer particles is quite satisfactory as an ultraviolet-shielding adjuvant in water-base cosmetic or toiletry preparations in respect of good stability of dispersion, high ultraviolet-shielding power and surface lubricity.
