Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) defers its safety assessment of Aluminum Powder (CI 77000) to the FDA. The FDA sanctions its use as a color additive, exempt from certification, for externally applied cosmetics, including those for the eye area, but explicitly prohibits its inclusion in lip products. The Scientific Committee on Consumer Safety (SCCS) concluded in 2023 that aluminum compounds are safe when used within specified maximum levels in non-sprayable and sprayable products, provided that for sprayable applications, particles/droplets with a diameter less than 10 μm do not exceed 20% of the total aerosolized content. CI 77000 is listed in Annex IV of the EC Cosmetics Regulation as a permitted colorant, conditional on meeting stringent purity requirements.
