HigH PE rForming titAnium DioXiDE DiSPEr SionS leveraging a new patented coating system and pure photostability science introDuCtion HIGH PERFORMING Metal oxides with a wide band gap, such as Titanium Dioxide (TiO 2), or with a direct band gap, such as Zinc Oxide (ZnO), absorb and reflect UV energy from the sun’s radiation. This makes TITANIUMthem useful as UV filters and as DIOXIDE pigments in the cosmetic industry. Unfortunately, they are also photo-active, promoting the formation of reactive oxygen species and catalyzing the decomposition of organic materials. This is not desiredDISPERSIONS in personal care applications, where the protective functions of these organic compounds are needed. CommercialLEVERAGING surface modifications A NEW have PATENTED not eliminated COATING this degradation, so a new means of protection was needed.
