ULTRAVIOLET ABSORBENT TITANIUM DIOXIDE OIL DISPERSION USEFULLY IN COSMETIC COMPOSITIONS SUCH AS SOLAR CREAMS

摘要

The subject of the invention is an oily dispersion comprising an oil, titanium dioxide particles and a dispersing agent for said particles. / P P The dispersion according to the invention is characterized in that the particles of titanium have an average size of 0.01 to 0.15 mum and the amount of said particles is such that the dispersion has a solids content of more than 40% by weight and said dispersing agent is organic and said dispersion is substantially transparent to the visible light and substantially absorbs UV light, so that the dispersion has a maximum extinction coefficient E (max) in the ultraviolet wavelength range of at least 40 lg ** - ** 1.cm * * - ** 1. / P P Applications: manufacture of compositions substantially transparent to visible light and practically absorbing UV, in particular sun creams.
