Monostearin CAS 123-94-4

Monoglyceride (MG) is known as monofatty acid glyceride (or glycerol monofatty acid ester), which has two configurations, i.e., 1-MG and 2-MG.According to the name of the main fatty acid, monoglyceride can be classified into glycerol acetate monostearate, glycerol acetate monolaurate, glycerol acetate monooleate and so on, among which the most widely produced and applied is glycerol acetate monostearate. Glyceryl monostearate is generally oily, greasy or waxy, with light yellow or ivory colour, greasy taste or no taste, which is related to the size and saturation degree of fat group, and has excellent sensory characteristics. In addition, glyceryl monostearate is a polyol type nonionic surfactant, due to its structure has a lipophilic long chain alkyl and two hydrophilic hydroxyl, thus has good surface activity, can emulsify, foam, dispersion, defoaming, anti-starch aging and other functions, is the most widely used in food and cosmetics of an emulsifier. In addition, there are important uses in the pharmaceutical industry, such as polyunsaturated fatty acids (EPA, DHA) glycerol esters have the role of preventing cardiovascular disease. In the field of polymer synthesis, glycerol monostearate also has a wide range of applications.

1.Performance and use:

Glyceryl monostearate is a common emulsifier widely used in the food, pharmaceutical, cosmetic and detergent industries. Due to the interaction of monoglyceride with fats and oils, it can promote the generation of its crystal form, with the effect of improving the ductility, esterification and water absorption of plastic fats and oils, as well as preventing spattering during heating, etc., and has been used in the production of margarine, shortening, mayonnaise, seasonings and other special fats and oils. Glycerol monostearate interacts with gluten proteins to form a symmetrical complex of a protein-like lipid-protein and a starch-like lipid-protein, thus enhancing gluten quality. At the same time, it is also the mother of lactic acid monoglyceride, citric acid monoglyceride, luciferic acid monoglyceride, diethyl phthalate tartaric acid monoglyceride and other series of emulsifiers; monoglyceride can be added to improve the flavour of food and its functionality. At the same time it has many other application properties. In polyethylene processing monoglyceride used as an internal lubricant, can promote the smooth progress of gelation, improve fluidity. In polyolefin, monoglyceride is used as antistatic agent, which can leak out the static electricity on the surface of plastic, avoiding the electric shock barrier of the products, preventing the surface of the products from adsorption of dust and becoming dirty, and at the same time reducing the surface friction of electricity. Monoglycerides in plastics used as anti-fogging agent, can eliminate agricultural film fogging and affect the sunlight transmittance and dripping caused by crop growth and other harmful effects of fog, while also eliminating the fogging fuzzy phenomenon in the food packaging film, to improve the aesthetics of the contents and the value of the goods. Synthesis technology

Widely used in cosmetic industry, especially in shampoo shampoo, bath agent is more widely used in food or cosmetics as emulsifiers and surfactants, but also plastic products inside and outside the lubricant used as gas chromatography fixative, dispersant and emulsifier, also used in the pharmaceutical industry, biochemical research, margarine thickening, solvents, emulsifiers, oils and waxes, etc., the protection of hygroscopic powders, opaque Opacifying agent. Gas chromatography stationary liquid (maximum use temperature 125 ℃, solvent for hot ethanol), separation and analysis of oxygenated compounds and volatile oils
