Nanotechnology and micronization both refer to the practice of creating very small particles sizes of a given material. Micronized TiO2 (also called “nano” or “nanoparticles”) was introduced in the early 1990s. Some shapes can be converted to nanomaterials. Titanium dioxide can form several different shapes, which have different properties. It is used in a wide variety of personal care products, including color cosmetics such as eye shadow and blush, loose and pressed powders and in sunscreens. It is also resistant to ultraviolet (UV) light, and is used widely in sunscreens and pigments that are likely to be exposed to UV light. It is naturally opaque and bright, which makes it useful for use in paper, ceramics, rubber, textiles, paints, inks and cosmetics. It was first intentionally produced for use as a white pigment in 1923. Titanium dioxide (TiO2) is a fine white powder or dust that occurs naturally. ![]() Titanium dioxide nanoparticles do not appear to confer any unique health hazards. However, when titanium dioxide is inhalable-as it may be when in powder form-it is considered a possible carcinogen by the International Agency for Research on Cancer. In lotions and creams (dermal exposure), it is not a risk for adverse health effects. Titanium dioxide (TiO2) is used in a variety of personal care products, including sunscreens, pressed powders, and loose powders, as a UV filter or whitening agent.
