Polyethylene glycol PEG-6000 can be used in pharmaceuticals. Peg has a relatively low molecular weight and can be used as a solvent, cosolvent, O/W emulsifier and stabilizer. Used for making cement suspending agent, emulsion, injection, etc. , also used as a water-soluble ointment base and suppository base. High molecular weight solid waxy polyethylene glycol (PEG) is often used to improve the viscosity and fixation of low molecular weight liquid PEG, and to compensate for the deficiency of other drugs. For insoluble drugs in water, it can be used as the carrier of solid dispersant to prepare tablets, pills, capsules, microcapsules and so on.

Polyethylene glycol PEG-6000 in the pharmaceutical industry as a molding agent, suppository and paste preparation; Used as coatings in the paper industry to increase the gloss and smoothness of paper; As an additive in the rubber industry, it can increase the lubricity and plasticity of rubber products, reduce the power consumption in the processing process, prolong the service life of rubber products, and be used as a matrix in the pharmaceutical and cosmetic industry to adjust the viscosity and melting point; Used as lubricant and coolant in rubber and metal processing industry, as dispersant and emulsifier in pesticide and pigment industry; Used as antistatic agent and lubricant in textile industry. It can be used as raw material of ester surfactant.
