Product Description

Polysorbate 20 - 32 oz

Polysorbate 20 (common commercial brand names include Alkest TW 20 and Tween 20) is a polysorbate surfactant whose stability and relative non-toxicity allows it to be used as a detergent and emulsifier in a number of domestic, scientific, and pharmacological applications. It is a polyoxyethylene derivative of sorbitan monolaurate, and is distinguished from the other members in the polysorbate range by the length of the polyoxyethylene chain and the fatty acid ester moiety. The commercial product contains a range of chemical species.

Data: Polysorbate 20's cmc is 8.0410-5 M at 21 C. This corresponds to 0.0987 g/L or approximately 0.01% w/v. Polysorbate 20's hydrophile-lipophile balance (HLB) is: 16.7. HLB number is a measure of how much a surfactant will move into the water and oil phase. A high HLB number like 16.7 indicates that the surfactant will travel into the water phase.
