Product Information

Aceto offers both sourced and proprietary forms of Polysorbarte 20 to enable customers the best choice for fit and function. A&Cā€™s Polysorbate 20 is an excipient which meets the NF monograph. It appears as a yellow liquid and is soluble in cold water. Polysorbate 20 is a non-ionic surfactant, which originated from sorbitan esters. Its suffix of ā€œ20ā€ derives from the amount of ethylene oxide added (the polyoxyethylene) to the base sorbitan monolaurate; in this case, a chain of twenty.
