Polyethylene glycol is non-toxic and has excellent water solubility, solubility, lubricity, adhesion and thermal stability. Therefore, as a lubricant, dispersant, adhesive, excipient, etc., widely used in medicine, veterinary medicine and cosmetics industry.
Polyethylene glycol PEG is made of ethylene oxide and water or ethylene glycol as raw materials through gradual addition reaction. Its raw materials are mainly from petroleum products. Polyethylene glycol (PEG) is a polymer of ethylene oxide and water. It is a white paraffin-like or powdery solid with no peculiar or faint odor. It is non - toxic, non - irritating, water - soluble and soluble in many organic ingredients. They have excellent lubricity, moisture retention, dispersity, adhesives, antistatic agents and softeners.
With the increase of polymerization degree, the physical appearance and properties of PEG gradually change. When the relative molecular weight is between 200 and 600, it is normal temperature liquid, and when the relative molecular weight is greater than 600, it gradually becomes semi-solid. The higher the molecular mass, the lower the hygroscopicity, and the transition from a colorless, odorless liquid to a waxy solid. It has the chemical properties of alcohol and produces esters by esterification with fatty acids. Soluble in water, ethanol and various organic solvents. Does not affect a variety of heat, acid, alkali stability and a variety of chemicals. It has good moisture absorption, adhesion and lubricity. Non-toxic and non-irritating. Harmless to humans and animals.
PEG series products are mild toxic, non-irritating, water soluble and soluble in various organic ingredients. They are widely used in cosmetics, pharmaceutical, chemical fiber, rubber, plastic, paper making, paint, electroplating, pesticides, metal processing, biological engineering and food processing industries with excellent lubricity, moisture retention, dispersion, adhesive, antistatic agent and softener
