Ci 77220

CI 77220 is an inorganic colorant (commonly used as a cosmetic pigment) typically present at low percentages in makeup and tinted skincare, where it functions as an insoluble particulate rather than a reactive active. In clinical use, such mineral pigments are generally well tolerated, but in highly reactive or barrier-impaired skin they can contribute to mild irritation via friction/particle load or contamination/impurities, so it is not scored as fully inert. Overall, the irritation potential is low at typical concentrations, consistent with a 'very gentle' rating while still acknowledging sensitive-skin edge cases. Safety Notes: CI 77220 (Calcium Sulfate) is used as a bulking agent, absorbent, and opacifier in cosmetic products. At the low end (0.01-0.1%), it appears in liquid foundations and serums as a minor opacity modifier. At the high end (15-25%), it's a primary ingredient in powder formulations including face powders, dry shampoos, body powders, and pressed powder compacts where it serves as a major bulking and absorbent component.
