High molecular weight polyethylene glycol (Mr > 2000) is suitable for the lipstick, deodorant stick, soap, shaving soap, foundation and beauty cosmetics.2: MedicineMedical polyethylene glycol (peg) is also called polyethylene oxide (PEO). Made by ring opening polymerization of ethylene oxide linear polyether. In the field of biomedical applications are as follows1) contact lenses with fluid2) synthetic lubrication medicine3) sustained release and carrier of the immobilized enzyme4) medical polymer materials surface modification5) to make contraceptive release. It alkoxide.6) production of hydrophilic anticoagulant polyurethane.7) polyethylene glycol 4000 as penetrative sugar-refining, can increase the osmotic pressure within the lumen, absorb moisture, to soften feces, volume increase, to promote intestinal peristalsis and defecation.8) denture fixative.9) experiment, on the study of the protein molecules can be simulated in a crowded environment, to verify the crowded environment of protein structure3: Food additiveAdditive Chinese name: Polyethylene glycol (peg)Allows the use of the additive of food Chinese name: Candy, chocolate products coatingPacking And Shipment Fedex/DHL/TNTShiping By AirShiping By SeaSuitable QuantityUnder 25KGUnder 100KGMore Than 100KGShipment Time3-10 Days5-15 Days15-45 DaysShiping CostHigh CostHigh CostLost CostServiceDoor to DoorDoor to AirportPort To PortOtherEasy To Pick Up GoodsProfessional Broker is NeededABOUT USFAQQuestion 1:Can you supply free samples ?Answer:Because so many free sample orders everyday to us, sorry, we need to supply sample with charge, but sample charge can be deducted from future orders.Hope you can understand.Question 2: How to assure your delivery same good quality as sample?
