CI 77745 (Manganese Phosphate)

INCI: CI 77745

CAS Number
10236-39-2
Function
Colorant. Inorganic pigment based on manganese phosphate (Mn3(PO4)2). Produces pinkish-beige to light brown tones depending on oxidation state and processing. Used in cosmetic products such as eye shadows, blushes, and face powders as a subtle natural-looking colorant. Chemically stable, resistant to light and heat, and inert in cosmetic formulations. Distinguished from CI 77742 (Manganese Violet/manganese ammonium pyrophosphate), which is a different manganese compound with a different hue.
