Employed in pharmaceutical applications. Lower molecular weight variants serve as solvents, co-solvents, and O/W emulsifiers, stabilizing emulsions and cement injections. They are also utilized as water-soluble ointment bases and suppository foundations. Higher molecular weight waxy solid versions enhance the viscosity and settling properties of lower molecular weight liquid PEG. These are employed as carriers for solid dispersants. PEG4000 and PEG6000 find favor as materials for capsules, hydrophilic substances, webbing, bladder materials, plasticizers, lubricants, and the base for producing lozenges, pills, capsules, and microcapsules, among other uses. Utilized as a fundamental ingredient in ester surfactant production.
PEG200 can be harnessed as an organic synthesis medium and a high-temperature heat carrier, functioning as a humectant, inorganic salt solubilizer, and viscosity regulator in the daily-use chemical industry. It also acts as a softening agent and antistatic agent in the textile sector, a wetting agent in the papermaking industry, and for pesticide applications.
PEG400, PEG600, and PEG800 serve as bases in pharmaceuticals and cosmetics, while also functioning as lubricants and wetting agents in the rubber and textile industries. The addition of PEG600 to electrolytes can enhance grinding effectiveness in metal processing.
PEG1000 and PEG1500 act as substrates, lubricants, and softening agents in the pharmaceutical, textile, and cosmetic sectors. They are employed as dispersants in bead paint and rubber industries to boost sulfidation and serve as dispersants for black carbon fillers.
PEG2000 and PEG3000 are applied as coolants, lubricants, and cutting oils in metal stripping, stamping, and molding processes. They serve as brighteners and soldering agents for metal processing cooling and lubrication.
PEG4000 and PEG6000 are utilized as substrates in the pharmaceutical and cosmetic industries for viscosity and melting point adjustments. They function as lubricants, release agents, and coolants in the rubber and metal processing industries. Moreover, they act as dispersants and emulsifiers in the pesticide and coloring industries and as adhesives for antistatic, lubrication, and polishing purposes in the textile sector.

1.Polyethylene glycol series products can be used in pharmaceuticals. Polyethylene glycol with low relative molecular weight can be used as solvent, co-solvent, O/W emulsifier and stabilizer, used to make cement suspensions, emulsions, injections, etc., and also used as water-soluble ointment matrix and suppository matrix, solid waxy polyethylene glycol with high relative molecular weight is often used to increase the viscosity and solidification of low molecular weight liquid PEG, as well as compensate other drugs; For drugs that are not easily soluble in water, this product can be used as a carrier of solid dispersant to achieve the purpose of solid dispersion, PEG4000, PEG6000 is a good coating material, hydrophilic polishing materials, film and capsule materials, plasticizers, lubricants and drop pill matrix, for the preparation of tablets, pills, capsules, microencapsulations, etc.
