Description :

Polysorbate 80 is a nonionic surfactant and emulsifier derived from sorbitol which comes from fruit and berries. Polysorbate 80 is a highly viscose water-soluble yellowish liquid used as a dispersing agent -mixes oil and water, stabilizer and lubricates.

Characteristics and Application :

Polysorbate 80 is a nonionic surfactant and emulsifier derived from polyethoxylated sorbitan and oleic acid, and is often used in foods. Polysorbate 80 is a viscous, water-soluble yellow liquid. The hydrophilic groups in this compound are polyethers also known as polyoxyethylene groups which are polymers of ethylene oxide. In the nomenclature of polysorbates, the numeric designation following polysorbate refers to the lipophilic group, in this case the oleic acid .

Polysorbate 80 is often used in ice cream to prevent milk proteins from completely coating the fat droplets. This allows them to join together in chains and nets, to hold air in the mixture, and provide a firmer texture, holding its shape as the ice cream melts

Uses :

Polysorbate 80 is used as an emulsifier in the manufacture of medications for parenteral administration, most notably in the popular anti-arrhythmic amiodarone.
