Titanium dioxide, with the chemical formula TiO2, has the CAS number 13463-67-7. It is a white solid that appears as a fine powder. Titanium dioxide does not have a distinct odor. Its basic structure consists of one titanium atom bonded to two oxygen atoms. This compound is insoluble in water. Titanium dioxide is considered to be non-toxic and safe for use in various applications. However, inhalation of its fine particles may cause respiratory irritation. It is important to handle titanium dioxide with care and avoid prolonged exposure to its dust.
Applicable Fields
Cosmetics: Titanium dioxide is widely used in the cosmetics industry. Its purpose in this field involves its ability to provide a white pigment and opacity to cosmetic products. The mechanism of action in cosmetics is based on the scattering and reflection of light by titanium dioxide particles, which helps to create a smooth and even appearance on the skin.
Paints and Coatings: This compound is commonly used as a pigment in paints and coatings. Its purpose in this field involves its ability to provide whiteness, brightness, and opacity to the finished product. The mechanism of action in paints and coatings is similar to that in cosmetics, where titanium dioxide particles scatter and reflect light, enhancing the visual properties of the coating.
Sunscreen: Titanium dioxide is also used in sunscreens as a physical UV filter. Its purpose in this field involves its ability to absorb and reflect UV radiation, providing protection against harmful sun rays. The mechanism of action in sunscreens is based on the formation of a protective barrier on the skin, preventing UV radiation from reaching the deeper layers.
Storage
Conditions: Store in a cool and dry place.
