Polyethylene glycol series products can be used in pharmaceuticals. Polyethylene glycol with a relatively low molecular weight can be used as a solvent, co-solvent, o/w emulsifier and stabilizer for making cement suspensions, emulsions, injections, etc., and can also be used as a water-soluble ointment base and suppository base. Solid waxy polyethylene glycol with high relative molecular weight is often used to increase the viscosity and solidification of low molecular weight liquid PEG, and 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 For the purpose of solid dispersion, PEG4000 and PEG6000 are good coating materials, hydrophilic polishing materials, film materials and capsule materials, plasticizers, lubricants and dropping pill matrices for the preparation of tablets, pills, capsules and microcapsules. wait.
Application:
1. PEG4000 and PEG6000 are used as excipients in the pharmaceutical industry for the preparation of suppositories and ointments; as coating agents in the papermaking industry to increase the gloss and smoothness of paper; and as additives in the rubber industry to increase the lubricity and smoothness of rubber products. Plasticity, reducing power consumption during processing and extending the service life of rubber products.
2. Polyethylene glycol series products can be used as raw materials for ester surfactants.
3. PEG-200 can be used as a medium for organic synthesis and a heat carrier with higher requirements. It is used as a moisturizer, inorganic salt solubilizer, and viscosity regulator in the daily chemical industry; it is used as a softener and antistatic agent in the textile industry. ; Used as wetting agent in paper and pesticide industries.
4. PEG-400, PEG-600, and PEG-800 are used as bases for medicines and cosmetics, and as lubricants and wetting agents in the rubber and textile industries. PEG-600 is added to the electrolyte in the metal industry to enhance the grinding effect and enhance the luster of the metal surface.
5. PEG-1000 and PEG-1500 are used as matrix or lubricant and softener in the pharmaceutical, textile and cosmetics industries; as dispersants in the coating industry; to improve the water dispersibility and flexibility of the resin, the dosage is 20~30% ; In ink, it can improve the solubility of dyes and reduce their volatility. It is especially suitable for wax paper and ink pad inks. It can also be used to adjust the viscosity of ink in ballpoint pen inks. It can be used as a dispersant in the rubber industry to promote vulcanization. Used as a dispersant for carbon black fillers.
6. PEG-2000 and PEG-3000 are used as molding agents for metal processing, lubricants and cutting fluids for metal wire drawing, stamping or forming, grinding, cooling, lubricating and polishing agents, welding agents, etc.; they are also used as lubricants in the papermaking industry, etc. Hot melt adhesive to add rapid rewetting capabilities.
7. PEG-4000 and PEG-6000 are used as substrates in the pharmaceutical and cosmetics industry to adjust viscosity and melting point; they are used as lubricants and coolants in the rubber and metal processing industries, and as pesticides and pigments in the industrial production. Dispersant, emulsifier; used as antistatic agent, lubricant, etc. in the textile industry.
8. PEG8000 is used as a matrix in the pharmaceutical and cosmetics industrial production to adjust viscosity and melting point; it is used as a lubricant and coolant in the rubber and metal processing industries, and as a dispersant and emulsifier in the pesticide and pigment industrial production; Used as antistatic agent, lubricant, etc. in the textile industry.
