Common Name(s): Manganese violet,permanent violet,manganese ammonium pyrophosphate

CAS Number: 10101-66-3

DESCRIPTION

What It Does: Provides stable mineral violet colour for cosmetic formulations.

Why It's Used: The only approved inorganic violet cosmetic pigment with excellent heat and light stability for process-demanding cosmetic applications.

How It Works: Manganese ammonium pyrophosphate provides violet colour from mn⁵⁺ d-d transitions. photostable mineral pigment. excellent heat stability for melt-process cosmetics. non-soluble in cosmetic matrices.

Typically Found In: Eyeshadow,lipstick,colour cosmetics

SCIENTIFIC NOTE

Manganese violet's mn⁵⁺ oxidation state is exceptionally rare in stable compounds – manganese most commonly exists as mn²⁺, mn³⁺, or mn⁴⁺. the mn⁵⁺ state in manganese violet's pyrophosphate lattice is stabilized by the high negative charge of the pyrophosphate anions, providing a thermodynamically unusual but chemically stable oxidation state that provides the specific d-d transition energy for violet colour.
