CI 77891
Is CI 77891 safe for seborrheic dermatitis?
CI 77891 is not automatically unsafe for seborrheic dermatitis, but its ingredient-specific evidence is too limited for a universal verdict. This name usually identifies titanium dioxide used to make a cosmetic white or opaque. It does not tell you how the powder is treated or how the finished product will feel.
No reliable evidence found for this page shows that CI 77891 feeds Malassezia or treats seb derm. A tinted cream, makeup powder and rinse-off product create very different exposure, and the surrounding emollients, binders or fragrance may matter more. Choose a comfortable formula and stop if irritation repeatedly increases.

What is CI 77891 used for in skincare?
CI 77891 is the Colour Index name for titanium dioxide when it is used as a white pigment or opacifier. It helps control colour, coverage and transparency in makeup and skincare. This entry does not by itself mean the product is a tested sunscreen, because titanium dioxide can serve different roles in different formulas.
