Polyethylene glycol series products can be used for pharmaceuticals. Polyethylene glycol with low relative molecular weight can be used as a solvent, co solvent, O/W emulsifier, and stabilizer for the production of cement suspensions, emulsions, injections, etc. It is also used as a water-soluble ointment and suppository base. Solid waxy polyethylene glycol with high relative molecular weight is commonly used to increase the viscosity and solidity of low molecular weight liquid PEG, as well as to compensate for other drugs; For drugs that are not easily soluble in water, this product can be used as a carrier for solid dispersants to achieve the purpose of solid dispersion.
