E171

E171, also known as titanium dioxide, is a white pigment used to whiten and brighten products like candies, toothpaste, and cosmetics. It consists of tiny particles of titanium dioxide that reflect light, giving items a fresh, clean appearance. While widely used for its effective coloring and safety approval in many countries, ongoing research examines potential health effects of inhaling or consuming these particles in large amounts. Regulatory agencies have set guidelines to ensure its safe use, but some consumers choose to avoid products containing E171 due to these discussions.
