Titanium Dioxide On Mica

Titanium dioxide on mica is a color additive used to create shimmering or pearlescent effects. It consists of tiny mica flakes, which are naturally occurring silicate minerals, coated with titanium dioxide, a white mineral oxide. This combination is processed to achieve a lustrous appearance.

Manufacturers add titanium dioxide on mica to foods primarily for its decorative properties, providing a pearlescent or metallic sheen. It is frequently used in confectionery, baked goods, and other decorative food coatings to enhance visual appeal.

In the United States, titanium dioxide, including its use on mica, is an FDA-approved color additive for food. It is generally recognized as safe for its intended use under current regulations. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated titanium dioxide and set an acceptable daily intake. However, in 2021, the European Food Safety Authority (EFSA) concluded that titanium dioxide could no longer be considered safe as a food additive due to concerns about genotoxicity, leading to its ban in the EU in 2022. Despite the EU ban, titanium dioxide remains permitted by the FDA as a food additive in the United States and is not part of the FDA's proposed phase-out of petroleum-based synthetic dyes.
