Titanium Dioxide is a natural mineral used to whiten cosmetics, soaps, toiletries, etc. Two common forms used are Anastase and Rutile. On this page you are purchasing RUTILE. All our other Titanium Dioxides are Anastase form. In addition, this product has been surface-treated with Sodium C14-16 Olefin Sulfonate. As a result the product disperses extremely easily in any water-phase product (no clumping or separation).
