Polyethylene glycol and polyethylene glycol fatty acid ester used in the cosmetics industry and the pharmaceutical industry is very wide. Since both polyethylene glycol many excellent properties: a water-soluble, non-volatile, physiologically inert, mildness, lubricity and wetting the skin, soft, pleasant after feel like. You can select different molecular weight fractions of polyethylene glycol to change the viscosity of the products, absorbent and organizational structure. Low molecular weight polyethylene glycol (Mr2000) applies lipstick, deodorant sticks, soap, shaving soap, foundation and cosmetics and the like. In cleaning solvents, polyethylene glycol is also used as suspending agents and thickening agents. In the pharmaceutical industry, it is used as ointments, creams, ointments, lotions and suppositories matrix. Commercially available with food and drug use polyethylene glycol (such as Polyethylene Glycol NF, Dow chemical Co.) is more suitable for cosmetic use. Methoxy polyethylene glycol and polypropylene glycol, polyethylene glycol and similar applications. Polyethylene glycol is widely used in a variety of pharmaceutical preparations, such as injections, topical preparations, ophthalmic preparations, oral and rectal formulations. Solid polyethylene glycol can be added to the level of liquid polyethylene glycol adjust viscosity for topical ointment; polyethylene glycol suppository bases can be used as a mixture of; aqueous polyethylene glycol can be used as suspending agents or for adjusting other polyethylene glycol and other emulsifier combination, increase emulsion stability; viscosity of the suspending medium. In addition, the polyethylene glycol is also used as a film coating agent, tablet lubricants, controlled-release materials.
