Product Description:
Polyethylene glycol and polyethylene glycol fatty acid esters are widely used in cosmetic industry and pharmaceutical industry. Because polyethylene glycol has many excellent properties: water-soluble, non-volatile, physiologically inert, mild, lubricating, and makes the skin moist, soft, and pleasant after use. Polyethylene glycol with different relative molecular mass fractions can be selected to change the viscosity, hygroscopicity and organizational structure of the product.
Polyethylene glycol (Mr<2000) with low molecular weight is suitable for wetting agent and consistency regulator, used in cream, lotion, toothpaste and shaving cream, etc., and also suitable for non-cleaning hair care products , giving 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 glycol is also used as a suspending and thickening agent. In the pharmaceutical industry, used as a base for ointments, creams, ointments, lotions and suppositories.
