 Emulsifier
Remarks：

 

[CAS RN.]: 1592-23-0
[EINECS]: 216-472-8
[Molecular Weight]: 607.023
[Molecular Formula]: (C18H35O2)2Ca
[Melting Point(℃)]: 145 - 160 
[Description]:
Calcium Stearate is fine white nontoxic and no curing pollution with specific gravity 1.08. It can slightly dissolve in hot ethanol, but not in water.It will be decomposed to stearate or sale when meet strong acid and can absorb moisture in air. Much attention shall be paid during storage and transportation. 
[Applications]:
Calcium Stearate has good thermal stability, but poorer than lead stearate ans barium stearate. It is better if used with zinc or epoxy compound, so it is widely used for the nontoxic products. PVC can become light red at 160 or heated for a long time. If in a large quantity, there will be frost phenomenon.

[Molecular formula]: Ca(CH3(CH2)16COO)2
[Characters]: It is white, fine powder, puff, greasy to touch, soluble in hot water, ethanol, aether.
[Usage]: It is widely used in medicine, food, cosmetics etc, used as emulsifier, releasing agent, lubricant, stabilizer, thickener, accelerant etc.
[Package]: The PE film lined the polywoven bag. Net wt: 20kg/bag, or follow customer’s packing instructions
