TTO-55(C)

Titanium Dioxide (Nano). TTO-55(C) by Nagase is a rutile, ultrafine titanium dioxide that can be used as a UV-A & UV-B filter. Among mineral-based UV filters, titanium dioxide is known for its high level of safety and sustainability. It causes minimal irritation to the skin, making it the ideal choice for baby sunscreens and products for those with sensitive skin. Its range of wavelength absorption is between 290 and 340 nm. It has low photoactivity and low concentrations of heavy metals. It is photo-stable, shows hydrophobicity and offers sun protection. Compared to other grades, TTO-55(C) can shield against even longer wavelengths (UV-A), but has low transmittance in the visible region. Consequently, it is recommended for use in base makeup products that do not require high transparency. Before blending, it is recommended to disperse this product once in, for example, a highly polar ester oil. It is used in skin care and color cosmetics.
