Chemical Name:

Sorbitan Ester Polyethylene Glycol Ether

Trade Name:

KEPS

Introduction:

Polysorbates are oily liquids produced by ethoxylation of sorbitan esterified with fatty acids. All of them have 20 ethylene oxide unit in the molecule. The number following the name of polysorbate is related to the type of fatty acid associated with the polyoxyethylene sorbitan part of the molecule.

General Applications:

Polysorbates are a class of emulsifiers used in pharmaceuticals and food formulations. They are often used in cosmetics to solublize essential oils into water-based products.

Different grades:

KEPS 20, KEPS 60, KEPS 80
