Oxide Dispersion

Titanium Dioxide Nanoparticles Dispersion is non-toxic and chemical properties are stable. It almost has no reaction with other material produce under normal temperature. It is a partial acid oxide. It has no reaction with oxygen, hydrogen sulfide, sulfur dioxide, carbon dioxide and ammonia and is not soluble in water, fatty acids, other organic acid and weak inorganic acid except for alkali and hot nitric acid.

Titanium Dioxide Nanoparticles Dispersion is mostly used as white pigment because of its high diffraction index, strong light scattering, incident-light reflection capability and a high UV resistance that make TiO2 the standard pigment found in white dispersion paints with high hiding power. TiO2 pigments used are almost exclusively rutile modification particles with grain sizes in the micrometer range. These white pigments are not only found in paints and dyes but also in varnishes, plastics, paper and textiles.

The potential toxicity of titanium dioxide nanodispersion is a controversial subject. Many cosmetic companies use titanium dioxide nanoparticles. Because of its bright whiteness, it is used in products such as paints, coatings, papers, inks, toothpaste, face powder, and food coloring.

TiO₂ dispersions are non-toxic and therefore are used in cosmetic products (sunscreens, lipsticks, body powder, soap, pearl essence pigments and tooth pastes) and also in special pharmaceutics. TiO₂ is even used in food stuffs. TiO₂ photo catalytic characteristics are greatly enhanced due to the advent of nanotechnology.
