Polyethylene Glycol Chemical Used in Pharmaceutical Industry

Product Information

Polyethylene glycol is a kind of polymer, which is one kind of Industrial Ethylene.

Polyethylene Glycol Uses
1. Biomedical applications
Medical polyethylene glycol is also known as polyethylene oxide (PEO). It is a linear polyether obtained by ring-opening polymerization of ethylene oxide. The main applications in the biomedical field are as follows:
(1) Contact lens solution. The viscosity of the aqueous solution of polyethylene glycol is more sensitive to the shear rate and bacteria are not easy to grow on the polyethylene glycol.
(2) Synthetic lubricants. Condensation polymer of ethylene oxide and water. For the preparation of water-soluble drugs ointment matrix, can also be used as acetylsalicylic acid, caffeine, nimodipine and other difficult to dissolve in water solvent for the preparation of injection.
(3) Carrier for drug slow release and immobilized enzyme. The aqueous solution of polyethylene glycol is coated on the outer layer of the pill, which can control the diffusion of the drug inside the pill in the body to improve the efficacy of the drug.
(4) Surface modification of medical polymer materials. Utilize amphiphilic copolymer containing polyethylene glycol to absorb on the surface of medical polymer materials (5) Make alkanol contraceptive film.
(6) Making hydrophilic anticoagulant Polyurethane .
(7) Polyethylene glycol 4000 for osmotic laxative, in the intestinal lumen can increase the osmotic pressure, absorb water, so that the feces soften, increase in volume, prompting intestinal peristalsis and defecation.
(8) Denture fixative. The use of polyethylene glycol non-toxic and adhesive, used as a component of denture fixative.
(9) in the study of protein molecules in the experiment, you can simulate the crowded environment in vivo, to verify the effect of the crowded environment on the structure of proteins
2. Used as food additives
Name of Additive : polyethylene glycol
Name of food allowed to use this additive: candy, chocolate products coating
Additive function: coating agent
3.Used as fusion promoter
This is an excellent chemical fusion promoter used in protoplast fusion. It is a polymer of ethylene glycol, with the chemical formula HO(CH2CH2O)nH. It is a white, slightly yellowish wax-like solid, soluble in water, with a slight odor.
4.Other
(1)Used as analytical reagent, also used in pharmaceutical industry;
(2)Used as softener, lubricant, etc;
(3)Used as matrix in medicine and cosmetics, dispersant, lubricant and emulsifier in rubber, metal processing, pesticide and other industries;
Medium for organic synthesis, moisturizer for daily-use cosmetic industry, solubilizer for inorganic salts, viscosity regulator, etc;
(4)Used as Flocculant , fluid friction reducing agent, textile-type infiltration agent, retention and filtration aids, adhesives, thickening agents and denture fixing agent;
(5)Used in cosmetics, pharmaceuticals, chemical fiber, rubber, paper, paint, electroplating;
(6)Used as molding agent, metal drawing, stamping and molding lubricant, paper industry lubricant, cutting fluid, grinding fluid cooling lubrication, polishing agent, etc.;
(7)Used as PVC lubricant, color masterbatch additive, textile softener, pigment dispersant, etc;
(8)As an additive for paper making, it can improve the retention rate of filler and fine fiber. It is an effective anti-flocculant. It can be added into pulping to improve the viscosity of pulp, prevent fibers from adhering to each other, improve the homogeneity of paper, reduce the power consumption of pulping, and improve the physical strength.

Company information

The company's main import and export products include

(1)）Petrochemicals：Refers to the use of oil or natural gas as raw materials, the manufacture of chemicals in the petrochemical industry of manufactured products, the same called petrochemical products.Our Petrochemicals include Special Oils And Fats, Solvent Oil , Fuel Oil and so on.

(2)Intermediates:It is a very important type of fine chemical products, the essence of a class of "semi-finished products", is the production of some products in the middle of the product, such as to produce a product, can be produced from the intermediates, cost savings, from the synthesis of pharmaceuticals, pesticides, paints, dyes and fragrances are widely used. In the pharmaceutical field, intermediates are an important link in the pharmaceutical industry chain, used in the process of drug synthesis of some chemical raw materials or chemical products, in a word, used to produce APIs.Our Intermediates products include Synthetic Material Intermediates,Dye Intermediates, Flavors and Fragrances intermediates.
