Monostearin price
Product name:Monostearin
CAS: 123-94-4
Molecular Formula: C21H42O4
Molecular Weight: 358.56
Product description:White or yellowish waxy solid, has a pleasant smell, the smell of fat. Soluble in hot organic solvents, such as ether, benzene, acetone and mineral oil, insoluble in water. But in the presence of a small amount of surfactant, can be dispersed in water. Median lethal dose (200 mg/kg mice, the abdominal cavity). Goods are often single palmitic acid glycerol monostearate and glycerol ester mixture. Monoglycerides is water-in-oil type emulsifier, sharp shock hitches in hot water and emulsification. Molecular distilled monoglycerides than crude ester with high purity, color white, emulsification effect is good. The emulsification and preservation effect of more than two times the coarse monoglycerides, bread amylose composite index can be from a coarse monoglycerides 28 92.As emulsifier and surfactant in food or in cosmetics, plastic products inside and outside the lubricant.
