EO/PO Block Copolymers

GASTAL L Series is a series of Block Copolymers of Ethylene oxide and propylene oxide that are of low enough molecular weight to be liquids at room temperature. An Alternate INCI and CTFA names are Poloxamers. The different percent of Ethylene Oxide in the molecule allows this chemistry to go from a Wetter/Defoamer to an excellent Scour/Dispersant.
