Propylene glycol stearate is a milky white solid at room temperature. no Soluble or dispersed in water and glycerol, soluble in propylene glycol, isopropanol and other solvents when heated. The hydrophobic part of its molecular structure is dominant, so it gives it the Emulsification Characteristics of water in oil. There is no mesomorphism in water. Monopropyl ester exists in a-crystal form and has no polycrystal, but it has a-crystal form tendency or tends to a-crystal form. In addition, it can stabilize the x-crystal form of other emulsifiers and has good aeration. These characteristics determine its application range
