The food-level titanium dioxide can be only produced by appointed enterprise in our company. At present, the technical index for food-level (equal to technical index of medicine) titanium dioxide of our company has exceeded standards of Chinese Pharmacopoeia and reached standards of America and European UnionPharmacopoeia.Titanium Dioxide Food Grade Tio2 is anatase titanium dioxide pigment manufactured by the sulphate process adopting international advanced technology and devices. It is designed to aim at reducing the heavy-metal content as far as possible and has successfully passed the SGS testing and BV testing. The product key features are owning very high purity, extremely low heavy-metal, and also has superior pigment performance such as bright-white gloss,excellent hiding power and tinting strength, very good dispersion and chemical stability. The combined properties of titanium dioxide food grade is similar to those international brands titanium dioxide used in medicine, food and cosmetic industries, Titanium Dioxide Food Grade complies with FDA USA (Commisssion directive 2006/33) and WHO/FAO specification as published in FAO Food & Nutrition Paper No. 52/1 and Z.etc.
