Author:Qingdao Yinuo Chemical Co. LTD

    Polyethylene glycol is nontoxic, nonirritating, and has excellent solubility, compatibility, lubrication, adhesion and thermal stability. Therefore, as lubricants, dispersants, adhesives, excipients and so on, in the pharmaceutical, veterinary and cosmetic industry as ointments, suppository matrix, drop pills, tablets carrier, molding agents and injection solvents, etc., have a wide range of applications.



    Polyethylene glycol PEG is a kind of ethylene oxide with water or ethylene glycol as the raw material through the gradual addition reaction to prepare, its raw materials are mainly from petroleum products. Polyethylene glycol (PEG) is a polymer of ethylene oxide and water. It is a white paraffin flake or powder solid, odorless or with a weak odor. It is non-toxic, non-irritating, has a good water solubility, and has a good compatibility with many organic components. They have excellent lubricity, moisture, dispersibility, adhesives, antistatic agents and softeners.

    With the increase of the degree of polymerization, the physical appearance and properties of PEG gradually changed, with the relative molecular weight between 200 and 600 as liquid at room temperature, and the relative molecular weight over 600 as semi-solid gradually. With the increase of molecular weight, the hygroscopic capacity of the liquid decreases as it changes from colorless and odorless viscous liquid to waxy solid. It has the chemical property of alcohol and can esterify with fatty acid to produce ester. Soluble in water, ethanol and a variety of organic solvents. It is stable to heat, acid and alkali and does not work with many chemicals. It has good moisture absorption, adhesion and lubricity. Non-toxic, no irritation. No harm to man or beast.

    Polyethylene glycol PEG series products are toxic, non - irritating, good water solubility, and has a good compatibility with many organic components. They are widely used in cosmetic, pharmaceutical, chemical fiber, rubber, plastic, papermaking, paint, electroplating, pesticide, metal processing biological engineering and food processing industries with excellent lubricity, moisture, dispersity, adhesive, antistatic agent and softener.
