INCI: Titanium dioxide (and) Silica Sunsafe-T microfine titanium dioxide blocks UV rays by scattering, reflecting, and chemically absorbing the incoming radiation. It can successfully scatter UVA and UVB radiation from 290 nm up to around 370 nm while allowing longer wavelengths (visible) to pass through. Sunsafe-T microfine titanium dioxide offers formulators a great deal of flexibility. It is a highly stable ingredient that does not degrade, and it provides synergy with organic filters.
