Titanium Dioxide Is It Safe-What Is Non Nano Titanium Dioxide

Non-nano titanium dioxide refers to a form of titanium dioxide (TiO2) where the particles are larger than 100 nanometers (nm) in size. Titanium dioxide is a common ingredient used in a variety of products, including sunscreen, cosmetics, paints, and food, primarily for its whitening and opacity-providing properties.

The term “nano” refers to the size of the particles, where a nanometer is one billionth of a meter. Nanomaterials, including nano titanium dioxide, have particles that are smaller than 100 nm. These small sizes can offer certain advantages, such as improved UV protection in sunscreens and better dispersion in products, but they also raise concerns about potential health and environmental risks due to their increased reactivity and bioavailability.

Non-nano titanium dioxide is considered by some to be a safer alternative to nano titanium dioxide because the larger particle size is thought to reduce the potential for these particles to penetrate the skin or be inhaled, which is a concern with nano-sized particles. Larger particles are less likely to enter cells and cause potential damage, and they are generally considered to be less reactive and more stable.

In the context of sunscreens, non-nano titanium dioxide is often preferred by those who are concerned about the potential risks of nanoparticles. However, it’s important to note that the safety of both nano and non-nano titanium dioxide is extensively studied and regulated by health authorities in many countries. The use of any form of titanium dioxide in products is subject to guidelines and restrictions to ensure safety for consumers.
