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 are widely used in cosmetic, pharmaceutical, chemical fiber, rubber, plastic, papermaking, paint, electroplating, pesticide, metal processing and food processing industries due to their excellent lubricity, moisture, dispersity, adhesives, antistatic agents and softeners.
Storage and transportation of POLYETHYLENE glycol (PEG) : this product is non-toxic and non-flammable. It should be transported as general chemicals and stored in a sealed dry place. Main USES: tablet, capsule, film coat, dropping pill, suppository, etc.
The high molecular weight PEG (PEG4000 and PEG6000) is useful as an adhesive for making tablets due to the plasticity of PEG during preparation and its ability to enhance drug release in tablets. PEG makes the surface of the tablet shiny and smooth, but not easily damaged.
The hygroscopicity of PEG is less than that of low molecular weight diols and less than that of glycerol, so the peg mixture is not sensitive to changes in ambient humidity, and its softness and plasticity remain high even after long-term storage. Peg is less volatile than diethylene glycol or triethylene glycol. Liquid polyethylene glycol (peg) 200-600 can provide wide selection hygroscopicity, especially suitable for plasticizer, rubber additives, can be used for the preparation of surface active agent, paint and ink, pharmaceutical, cosmetic, detergent, paper making, textile, food additives, leather processing, oil, wood processing, ceramics, agricultural, plating, photographic materials, adhesives and packaging materials, etc.
