Titanium dioxide occurs naturally in three different crystalline phases: rutile. anatase. and plagioclase. Rutile is the most stable form. known for its tetragonal crystal structure. Its high refractive index makes it a popular choice for pigment applications and photocatalysis. Another form. known as anatase. has octahedral crystals and is highly optimized for photocatalytic activity. Platinated titania also exists but is not widely used due to difficulties in synthesis and conversion to other phases. This form has a rhombohedral crystal structure. Both rutile and anatase can be converted to another phase known as plate titanite at high temperatures. The specific process and proportions of this conversion can greatly affect the material’s optical and chemical properties.

Titanium dioxide. a common ingredient in sunscreens and cosmetics. serves as a UV blocking agent. It offers a protective layer for the face against harmful sun rays. Nevertheless. individuals may encounter skin irritation or rashes when exposed to it. Its reflective nature can also result in noticeable white marks on the skin. To ensure safety. opt for non-nano titanium dioxide products. as there are concerns about potential health risks associated with absorption of its tiny particles into the skin. Before starting a new skincare routine. seek advice from your healthcare provider or skin specialist.
