CI 77891
Colorant
CI 77891, commonly known as Titanium Dioxide, is a mineral-based colorant widely used in cosmetics. Its primary function is to provide opacity and whiteness to formulations, making it a popular choice in products like foundations, sunscreens, and powders. Formulators may add CI 77891 not only for its coloring properties but also for its ability to reflect UV light, which can enhance the protective qualities of certain products. However, it is important to note that CI 77891 is subject to specific regulatory restrictions in cosmetic formulations.
