Product name: Widely Used In The Pharmaceutical Industry Polyethylene Glycol 4000
Main use: pharmaceutical excipient, ointment bulk material and lubricant,tablet, capsules and ect.
Due to the plasticity of PEG during the production process and its ability to improve the release of drugs from the tablet, high molecular weight PEG (PEG4000) is very useful as a binder for the manufacture of tablets. PEG makes the surface of the tablet shiny and smooth, while not easily damaged. In addition, a small amount of high molecular weight PEG (PEG4000) can prevent the adhesion between the icing tablets and the bonding between the bottle.
