PEG-400.600.800:Used as substrate for medicine and cosmetics, wetting agent and lubricant for rubber industry and textile industry.Peg-400 is suitable for soft capsule, because peg-400 is liquid, it has a wide compatibility with various solvents, is a good solvent and solvent, is widely used in liquid preparations, such as oral liquid, eye drops and so on.PEG is the preferred material when vegetable oil is not suitable for active ingredient carrier.This is mainly due to PEG stability, not perishable, PEG containing injection is very safe and stable when heated to 150 degrees Celsius.In addition, it can be mixed with high molecular weight PEG and the mixture has good solubility and compatibility with drugs.Peg-600 can enhance the grinding effect and the luster of metal surface by adding electrolyte in metal industry.

Polyethylene glycol is widely used in the cosmetic and pharmaceutical industries.Polyethylene glycol has many excellent properties:Water-soluble, non-volatile, physiologically inert, mild, lubricious and moistening.Soft and pleasant after use.Different relative molecular weight grades of polyethylene glycol can be selected to change the viscosity of products,hygroscopicity and organization.Peg with low molecular(Mr<2000) weight is suitable for wetting agent and viscosity regulator.Used in creams, lotions, toothpastes and shaving creams.It also applies to unwashed hair care products.Gives hair a silky sheen.Polyethylene glycol has a high relative molecular(Mr>2000) weight and is suitable for lipstick, deodorant stick, soap, shaving soap, foundation and beauty cosmetics.Polyethylene glycol is also used as a suspension and thickening agent among cleaning agents.Used in the pharmaceutical industry as a base for ointments, emulsions, ointments, lotions, and suppositories.Polyethylene glycol, which is commercially available for food and drug use, is more suitable for cosmetic use(for example.polyethylene glycol NF.Dow chemical Co.).Polyethylene glycol is widely used in a variety of pharmaceutical preparations, such as injections, topical preparations, eye preparations, oral and rectal preparations.Solid grade peg can be added to liquid peg to adjust viscosity.for topical application of ointment,Polyethylene glycol mixtures can be used as suppository substrates.An aqueous solution of peg can be used as a suspension aid or to adjust the viscosity of other suspension media.Peg is used in combination with other emulsifiers to increase emulsion stability. In addition, peg is used as film coating agent, tablet lubricant, controlled release material, etc.
