PEG-4000.6000.8000:Used for tablet, capsule, film coating, drop pill, bolus, suppository, etc.Peg-4000.6000 is used as an exoctant, suppository and paste preparation in the pharmaceutical industry.Used in the paper industry as a finishing agent to increase the gloss and smoothness of paper.In the rubber industry as an additive, increase the lubricity and plasticity of rubber products, reduce the power consumption in the processing process, extend the service life of rubber works.Used as a substrate in cosmetics industry to regulate viscosity and melting point.Used as lubricant and coolant in rubber and metal processing industry;Used as dispersant and emulsifier in industrial production of pesticides and pigments;Used as antistatic agent and lubricant in textile industry.High molecular weight PEG (4000.6000.8000) is useful as an adhesive for producing tablets due to the plasticity of PEG during the preparation process and its ability to improve drug release in tablets.PEG can make the surface of tablets shiny and smooth, and not easily damaged.In addition, a small amount of high molecular PEG prevents adhesive bonding between sugar coated tablets and medicine bottles.

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.
