Introduction to the product These series products of nano titanium dioxide are independently developed by our corporation and divided into two crystal forms of anatase and rutile with an appearance of white powder, high purity, characteristics of even granularity and average grain size of less than 100 nm. Nano titanium dioxide of our corporation has the properties of good transparency, and excellent absorbency to uva and uvb, except for the properties of normal titanium dioxide. It also has good properties of chemical stability, thermal stability. Nano titanium dioxide is insolubility in water, organic acid and weak inorganic acid, and solubility in sulfuric acid, alkali and hydrofluoric acid. Characteristics of the product Htti-03-h and htti-04-h are made for cosmetics. The model of htti-03-h is hydrophilic, while htti-04-h is lipophilic. These products have very good characteristics of even granularity and more excellent absorbency to uva and uvb than sun organic screener. They are widely and safely used as inorganic sun screener in the cosmetics and well compatible with other raw materials. They are the ideal additive of the sunscreen, anti-ultraviolet rays cosmetics.
