About
An inorganic manganese colorant used for brown/olive shades in cosmetic formulations, with manganese content requiring monitoring for skin absorption.
Ammonium manganese(III) diphosphate is an inorganic complex salt of manganese in the +3 oxidation state with phosphate ligands. Manganese-based colorants are used in decorative cosmetics for brown, olive, and khaki shades. The manganese oxidation state and solubility affect both color properties and safety. Soluble manganese compounds can be absorbed through skin, and the ECHA has flagged manganese compounds for neurotoxicity concerns at high exposure levels. Cosmetic use in leave-on products warrants monitoring, though concentrations are typically low.
Skin benefits
- Used as inorganic colorant for cosmetic preparations
Known concerns
- Manganese absorption concern - especially in leave-on products
- ECHA flagged for neurotoxicity concern at high exposure
