Polyethylene glycol series products can be used in pharmaceutical products. Polyethylene glycol can be used as solvent, cosolvent, O/W emulsifier and stabilizer, used for cement suspension, emulsion, injection and so on. It can also be used as a water-soluble ointment base and suppository base. Compared with high molecular weight solid waxy polyethylene glycol, it is often used to increase the viscosity and curing properties of low molecular weight liquid PEG and compensate for other drugs. For insoluble drugs in water, the product can be used as a carrier of solid dispersant to achieve the purpose of solid dispersion.
