Manganese stearate is a metal-organic compound, a salt of manganese and stearic acid with the chemical formula C
₃₆H
₇₀MnO
₄.^[1]^[2] The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid.^[3]

Synthesis

Manganese stearate is synthesized by the reaction of stearic acid with sodium hydroxide, followed by reacting with manganese chloride.^[4]

Also, the reaction of manganese(II) acetate with stearic acid.^[5]

The compound forms pale pink powder.^[6]

Insoluble in water.^[6]

The compound is used in organic synthesis reactions.^[6]

Also as an oxidant additive for oxo-biodegradable polymers (for example, high-density polyethylene).^[7]
