Summary: | A novel organic dispersion comprises microfine titanium dioxide and a suitable branched chain organic without the use of any dispersing agent. The novel dispersion provides uniquely high SPF with low levels of dry weight titanium dioxide. Methods for preparing said dispersion and cosmetic sunscreen compositions comprising said dispersion are also included within the invention.
Une nouvelle dispersion organique comprend du dioxyde de titane microfin et un agent organique à chaîne ramifiée sans utiliser d'agent dispersant. La nouvelle dispersion permet d'obtenir des facteurs de protection solaire extrêmement élevés avec des taux faibles de dioxyde de titane calculés sur le poids à sec. Des procédés de préparation de ladite dispersion et de compositions cosmétiques de protection solaire comprenant ladite dispersion sont également décrits dans l'invention. |
