Typical Properties
Summary
Magnesium stearate has good adhesion and lubricity to skin. It can be used in powder products in cosmetics to improve adhesion and lubricity. Magnesium stearate can be used as heat stabilizer of PVC, and its stability is similar to that of calcium stearate. It can be used in food packaging materials with zinc soap or calcium soap, but it is not widely used.
