Titanium Dioxide (Nano). MPT-171 by Nagase is a rutile, ultrafine titanium dioxide that can be used as 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 320 nm. MPT-171 has the advantage of being low in heavy metals. In addition, it is photo-stable, hydrophobic, has low cohesiveness and can easily be dispersed in the oil phase using a homogenizing mixer. It has particularly high transmittance even in the visible region, making it ideal for use in sunscreens that require a transparent finish.
