Calcium stearate is a white solid, nontoxic, insoluble in most solvents, slightly soluble in hot aromatic solvents, chlorinated hydrocarbons, vegetable oil, mineral oil, etc. It dehydrates and starts to soften at temperatures between 120℃ and 130 ℃，and takes a viscous consistency at approx. 160 ℃，and decomposes when the temperature is higher than 400 。In case of strong acid, it is decomposed into

Zinc stearate is a white solid, nontoxic, insoluble in most solvents, slightly soluble in hot aromatic solvents, chlorinated hydrocarbons, vegetable oil, mineral oil, etc. The melting point is about 120 ℃. After melting, it is a liquid with small viscosity. They are mainly used in the plastics and rubber industries ,and are used as release agents and lubricants due to their good compatibility.

Magnesium stearate is a white solid, insoluble in water, with high melting point. It is widely used in food, medicine, coating, plastic, rubber, textile and other industries, mainly as emulsifier, release agent, lubricant, stabilizer, accelerator, cosmetics base material, etc. It can be used in non-toxic products with calcium soap and zinc soap.

Barium stearate is a white powder solid, a long-term heat stabilizer with lubricant function. It has no sulfurization pollution and excellent initial coloring when used alone.
