Please Note: Although all of the oils we sell are all originally USP grade, they are purchased in bulk containers and re-bottled. The re-bottling process takes place in a very clean environment, with the utmost care for maintaining the product's purity. However, since the re-bottling process does not take place in an FDA certified clean room, these products are technically no longer USP grade. However, we guarantee the original potency of all re-bottled products.

Polyethylene Glycol - 300 (NF)
Common uses:
PEG can serve as the separator and electrolyte solvent in lithium polymer cells. Its low diffusivity often requires high temperatures of operation, but its high viscosity even near its melting point allows very thin electrolyte layers.
While crystallization of the polymer can degrade performance, many of the salts used to carry charge can also serve as a kinetic barrier to the formation of crystals.
Such batteries carry greater energy for their weight than other lithium ion battery technologies.
When working with phenol in a laboratory situation, PEG 300 can be used on phenol skin burns to deactivate any residual phenol.
