Polyethylene glycol and polyethylene glycol fatty acid esters are widely used in the cosmetic and pharmaceutical industries. Because peg has many excellent properties:
Water soluble, non-volatile, physiological inertia, mild, lubricious, moisturizing skin, soft, pleasant feeling after use, etc. Polyethylene glycol can be selected from different molecular weight levels to change the viscosity, hygroscopicity and structure of the product.
Polyethylene glycol (Mr2000) is used as a wetting agent and consistency regulator in comparison to its molecular weight, in creams, lotions, toothpastes and shaving creams, and also in dirty hair care products to give hair luster.
Polyethylene glycol (Mr>2000) is suitable for lipstick, deodorant stick, soap, shaving soap, foundation, beauty cosmetics, etc. Polyethylene glycol is also used as a suspending agent and thickener in cleaning agents.
In the pharmaceutical industry, it is used as a base for ointments, emulsions, ointments, detergents, and suppositories. PolyethyleneGlycolNF, Dowchemicalco., is more suitable for food and medicine
Methoxy polyethylene glycol and poly (propylene glycol) are used similarly to polyethylene glycol. Polyethylene glycol is widely used in injections, topical preparations, eye preparations, oral and rectal preparations and other pharmaceutical preparations.
Solid grade polyethylene glycol can add liquid polyethylene glycol to adjust the viscosity, used for local ointment; Polyethylene glycol mixture can be used as suppository base; Polyethylene glycol aqueous solution can be used as suspension agent or other suspension medium viscosity; Polyethylene glycol and other emulsifiers can increase the stability of emulsions.
In addition, polyethylene glycol is also used as film coating agent, tablet lubricant, controlled release material, etc.
