Polysorbate 20 is a fatty acid ester derived from Sorbitan Monolaurate. The number following the polysorbate is related to the type of fatty acid associated with the polyoxyethylene sorbitan part of the molecule. Monolaurate molecule has 20 repeat units of polyethylene glycol is indicated by 20.
Monolaurate is derived form Lauric acid, and is a saturated fatty acid. It is the main acid in coconut oil and in palm kernel oil. It is also found in human milk (5.8% of total fat), cows milk (2.2%), and goat milk (4.5%).

Uses:
1. Food applications
