About Polysorbate 20

The Polysorbates (comprising 20, 40, 60, and 80) are a series of non-ionic surfactants and emulsifiers derived from ethoxylated sorbitan esterified with fatty acids. Within the Food & Nutrition, Pharmaceutical, and BPC hierarchies, peg- the industry standard for stabilising O/W emulsions. While they share a common poly...
