HallBrite® PSF is a somewhat viscous fluid that, as an organomodified silicone, improves the feel and spreadability of sunscreen formulations. HallBrite® PSF is made by grafting a cyano diphenyl acrylate moiety onto a polysiloxane backbone. The resulting polymer provides formulations with superior organic compatibility, anti-whitening and detackification benefits, and enhanced substantivity and water resistance. It may also aid in dispersing metal oxides such as Titanium Dioxide, Zinc Oxide and Iron Oxides. The recommended use level for HallBrite® PSF is 1-8%.
