Description: PEG1500 is a polymer produced by the condensation reaction of ethylene oxide and water, generally white waxy solid in appearance, often used as a pharmaceutical excipient.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
