Source and Preparation

Stearate polyhydroxy 40 ester is mainly used as a suppository substrate, such as medrol, progesterone, chlorhexidine, indomethacin, etc. It can be used as the substrate and emulsifier of ointment to increase the decomposition and bioavailability of drugs, so as to make the appearance of ointment more delicate, white and emulsified evenly. Polyhydrocarbon oxy40 stearate can also be used as the matrix of dripping pills, and the dissolution of drugs in the dispersing system and the solubilization of drugs in the dissolution are superior. Stearate polyhydrocarbon oxy40 ester is used in the cosmetic industry as cream, conditioner and other oil-in-water products.
