Rutile micro titanium dioxide. Is made by surface processing t-butyl methoxy dibenzoylmethane with micro titanium dioxide. It solves the issue of t-butyl methoxy dibenzoylmethane crystallization to exhibit an excellent UV-A shielding effect and SPF effect. In addition, it maintains its UV shielding effect at a high-level due to the improved photodurability of t-butyl methoxy dibenzoylmethane.
