Monoglycerides chemical called glyceryl monostearate single eighteen (alkyl) acid esters of glycerol (Glycerin monostearate), referred to as monoglycerides (GMS), the molecular weight of 358. Industrial products usually tasteless, odorless, non-toxic yellow waxy solid or sheet, containing a small amount of di- and tri-esters. Quality index: Item GMS monoester content (%) 40-42 color white or pale yellow waxy solid traits powder or flake iodine value (gI2 / 100g) ≤ 3.0 Melting point (℃) ≥ 53 free acid (stearic acid Total,%) ≤ 2.5 heavy metals (Pb,%) ≤ 0.0005 arsenic (As,%) ≤ 0.0001 iron (as Fe,%) ≤ 0.0002 Note: Some indicators can be according to customer needs to be adjusted accordingly applications : monoglycerides in rigid PVC, UPVC sheet profiles, pipes, pipe fittings production as an internal lubricant, so that manufactures the surface smooth, shiny and does not bloom, for there is a certain PVC resin modified plasticizing effect; in lead salt composite stabilizer, rare earth compound stabilizer is essential lubricant, and can be used as synthetic latex paraffin dispersant and with the agent. Monoglycerides HLB value 3.6-4.0, is oil-soluble nonionic surfactants. As the emulsifier, an emulsion stabilizer and thickening agents are widely used in flavors, fragrances, moisturizers, ointments, hair lotions, shampoos, pharmaceuticals and other emulsion.
