Polyethylene Glycol PEG Classification And Function!

Polyethylene glycol is non-toxic, non-irritating, has excellent water solubility, compatibility, lubrication, bonding and thermal stability. Therefore, as a lubricant, dispersant, adhesive, excipient, etc., in medicine, veterinary medicine and cosmetics industry as a ointment, suppository matrix, dropping pills, tablet carrier, molding agent and injection solvent, etc., have a wide range of applications.

1, polyethylene glycol series products can be used for pharmaceutical. Polyethylene glycol with low relative molecular weight can be used as solvent, co-solvent, o/w emulsifier and stabilizer, used for making cement suspension, emulsion, injection, etc., and also used as water-soluble ointment base and suppository base. Solid waxy polyethylene glycol with high relative molecular weight is often used to increase the viscosity and solid formation of low molecular weight liquid PEG, as well as other drugs. For drugs that are not easily dissolved in water, this product can be used as the carrier of solid dispersant to achieve the purpose of solid dispersion. PEG4000 and PEG6000 are good coating materials, hydrophilic polishing materials, film and capsule materials, plasticizers, lubricants and dropping pill substrates, used for the preparation of tablets, pills, capsules, microcapsules and so on.

2, polyethylene glycol series products can be used as the raw material of ester surfactant.

3, polyethylene glycol PEG-200 can be used as a medium for organic synthesis and a heat carrier with higher requirements, used in the daily chemical industry as a moisturizer, inorganic salt solutizer, viscosity regulator; Used as softening agent and antistatic agent in textile industry; Used as a wetting agent in the paper and pesticide industries.

4, PEG4000, PEG6000 in the pharmaceutical industry as excipients, used as suppositories, paste preparation; Used as finishing agent in the paper industry to increase the gloss and smoothness of paper; As an additive in the rubber industry, it increases the lubricity and plasticity of rubber products, reduces the power consumption during processing, and extends the service life of rubber products.

5, PEG PEG-2000, PEG-3000 used as metal processing casting agent, metal drawing, stamping or forming lubricants and cutting fluids, grinding cooling lubrication polishing agent, welding agent, etc.; It is used in the paper industry as a lubricant, etc., and also as a hot melt adhesive to increase rapid rewetting capacity.

6, PEG8000 is used as a matrix in the production of medicine and cosmetics industry, which plays the role of adjusting viscosity and melting point; It is used as lubricant and coolant in rubber and metal processing industry, and as dispersant and emulsifier in pesticide and pigment industry production. It is used as antistatic agent and lubricant in textile industry.

7, PEG-4000, PEG-6000 in medicine, cosmetics industry production as a matrix, play the role of adjusting viscosity, melting point; It is used as lubricant and coolant in rubber and metal processing industry, and as dispersant and emulsifier in pesticide and pigment industry production. It is used as antistatic agent and lubricant in textile industry.
