Description
Titanium dioxide CI 77891 nano is a micronized form of the widely used white pigment titanium dioxide. This ultrafine particle version offers enhanced properties for skincare and cosmetic applications. With particle sizes typically ranging from 10 to 100 nanometers, it provides superior transparency and a smoother application compared to its larger particle counterparts.
In skincare formulations, titanium dioxide nano particles are primarily utilized for their UV protective capabilities. They effectively scatter and absorb both UVA and UVB radiation, providing broad-spectrum sun protection. This nano form allows for more aesthetically pleasing sunscreen formulations that are less likely to leave a white cast on the skin.
However, the use of nano-sized titanium dioxide has raised some safety concerns. While studies have shown limited dermal penetration, ongoing research examines potential long-term effects. Regulatory bodies, including the EU's Scientific Committee on Consumer Safety, have deemed it safe for use in cosmetic products up to certain concentrations.
Formulators must consider factors such as particle size distribution, surface coatings, and dispersion methods when incorporating this ingredient to ensure optimal performance and safety in finished products.
