1. Introduction
Name:Calcium stearate
Molecular formula:Ca[CH3（CH2）16COO]2
2. Characters
Calcium stearate is kind of fine white powder with greasy touch sense, soluble in hot water, methylbenzene, ethanol and other organic solvents, innoxious, slowly decomposes into stearic acid and calcium salts when it is heated to 400℃.
3. Applications
Calcium stearate is widely applied in food, medicine, cosmetic, plastic, rubber fields, mainly function as lubricant, emulsifier, stabilizer, releasing agent, accelerant etc. Also it is applied in the innoxiously soft film of food Package and medicine apparatus, can effectively improve film’s stability. It is halogen adsorbent in polyethylene and polypropylene, can eliminate the poor effect on resin’s color and stalibility because of catalyst remains. Besides it is widely used to improve plastic’s thermostability, better plastic’s air-conductivity, in future it will replace noxious stabilizer with same functions.
