Polyethylene glycol and polyethylene glycol fatty acid esters are widely used in the cosmetic and pharmaceutical industries. Because polyethylene glycol has many excellent properties: water-soluble, non-volatile, physiologically inert, mild, lubricating and moisturizing the skin, soft, and pleasant after use. Different relative molecular weight fractions of polyethylene glycol can be selected to change the viscosity, hygroscopicity and organizational structure of the product. Low molecular weight polyethylene glycol (Mr<2000) is suitable for use as wetting agent and consistency regulator for cream, lotion, toothpaste and shaving cream, etc. It is also suitable for unwashed hair care products. Gives hair a silky shine. Polyethylene glycol with high molecular weight (Mr>2000) is suitable for lipsticks, deodorant sticks, soaps, shaving soaps, foundations and beauty cosmetics. In cleaning agents, polyethylene glycols are also used as suspending and thickening agents. In the pharmaceutical industry, it is used as a base for ointments, creams, ointments, lotions and suppositories.

Polyethylene glycol is widely used in various pharmaceutical formulations such as injections, topical formulations, ophthalmic formulations, oral and rectal formulations. Solid grade polyethylene glycol can be added to liquid polyethylene glycol to adjust viscosity for topical ointment; polyethylene glycol mixture can be used as suppository base; aqueous polyethylene glycol can be used as suspending agent or used to adjust other The viscosity of the suspension medium; polyethylene glycol is used in combination with other emulsifiers to increase the stability of the emulsion. In addition, polyethylene glycol is also used as a film coating agent, a tablet lubricant, a controlled release material, and the like.
