Expert Verdict

CI 77000 (Aluminum Powder) is a metallic pigment permitted as a colorant in EU cosmetics under Annex IV with purity criteria per Commission Directive 95/45/EC. In the US, FDA grants permanent listing exempt from certification for externally applied cosmetics including eye area use under 21 CFR 73.2645, but explicitly excludes lip products. Formulators must not use CI 77000 in lipsticks or lip gloss for US market compliance. Good safety profile within approved non-lip external use scope.
