- Magnesium Stearate 1. Introduction Magnesium stearate Mg[CH3（CH2）16COO]2 2. Characters Magnesium stearate is a kind of tiny, light and white powder with greasy touch sense, insoluble in water, ethanol neither ethoxyethane, but soluble in hot water, hot ethanol, decomposes into stearic acid and magnesium salts when contacting with acid. 3. Applications Magnesium stearate is widely adopted in food, medicine, paint, plastic, rubber and textile fields and mainly function as emulsifier, releasing agent, lubricant, stabilizer, or accelerant etc. Also it can be used as stabilizer and lubricant in PVC or ABS resin etc. 4.（Specification） Test items Specification Appearance (tiny, light and white powder) Assay of Mg 4.0%~5.0% Loss on Drying ≤5.0% Free acid ≤1.0% Melting point 110~160℃ Particle size 325 99% (≥99% through 325 mesh) Bulk density 0.1~0.35g/ml 5.
