Manganese stearate is a metal-organic compound, a salt of manganese and stearic acid with the chemical formula (C₁₇H₃₅CO₂)₂Mn. The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid. ^[1] The pure solid is white, but some impure samples appear brownish. ^[2]

Synthesis and uses

Manganese stearate is synthesized by the reaction of sodium stearate with manganese chloride. ^[2]

It is a precursor to Mn-doped zinc selenide phosphors. ^[2]

Also as an oxidant additive for oxo-biodegradable polymers (for example, high-density polyethylene). ^[3]
