Polysorbate 20, MP Biomedicals™

Description

Polysorbate 20 is typically used as an emulsifying agent for the preparation of stable oil-in-water emulsions.

Tweens™ are a series of nonionic surfactants derived from sorbitan esters.

• They are soluble or dispersible in water but differ widely in organic and oil solubilities.
• Used as oil-in-water emulsifiers in pharmaceuticals, cosmetics, cleaning compounds, etc.
• Polysorbate 20 is nonionic surfactants derived from sorbitan ester.
