Abstract

A sunscreen nanomaterial SiO₂-KH550/TiO₂ was prepared by using rutile TiO₂ as carrier and KH550 as coupling agent by inorganic coating and organic grafting. Its hydrophilic, lipophilic and photocatalytic properties were investigated. The results showed that SiO₂-KH550/TiO₂ had good lipophilicity and could be well dispersed in the oil phase with good stability. After 6 h photodegradation, the degradation rate of methylene blue was only 17%, and the photocatalytic activity of TiO₂ was obviously reduced. The material could solve the problem that TiO₂ was easy to separate and settle in the oil phase system sunscreen cosmetics, and avoided the damage of epidermal cells caused by the photocatalytic activity of TiO₂ during the use of the product.
