1, polyethylene glycol 6000 is ethylene oxide and water condensation from the polymer, molecular formula HO(CH2CH2O)nH expressed, where N represents the average oxygen vinyl group, it is a non-toxic, non-irritating, widely used in a variety of pharmaceutical preparations. A range of products are available, depending on the degree of polymerization. Polyethylene glycol (PEG) is liquid when its molecular weight is less than 1000. If it's greater than 1000, it's solid.
2, POLYETHYLENE glycol has many excellent properties: water-soluble, non-volatile, physiological inertia, mild, lubricity and make the skin moist, soft, pleasant after use. The viscosity, hygroscopicity and microstructure of the product can be changed by using polyethylene glycol with different molecular weight grades. Polyethylene glycol (Mr<2000) with low molecular weight is suitable for use as a wetting agent and consistency modifier, for creams, lotions, toothpastes, shaving creams, etc., and also for uncleaned hair care products to give hair a silky sheen. Polyethylene glycol (Mr >2000) with high molecular weight is suitable for lipstick, deodorant bar, soap, shaving soap, foundation and cosmetic products. In detergents, PEG is also used as a suspension and thickener. Used in the pharmaceutical industry as a substrate for ointments, emulsions, ointments, lotions, and suppositories. Compulsory Polyethylene Glycol (such as Compulsory medicine NF, Dow Chemical Co.) is more suitable for cosmetics.
