Storage:
This product is non-toxic and flame retardant.
Regarded as a general shipments of chemicals, it should be
sealed and stored in dry place.

Function:
molecular weight of PEG600 larger than PEG400, while water solubility of PEG400 is larger than that of PEG600. As the PEG600 is liquid, it has a broad compatibility with various solvents, and is Good solvent and solubilizer. It has been widely used in liquid preparations, such as the oral solution, eye drops etc.
