Tween 80 is a polyethylene sorbitol ester containing approximately 20 units of ethylene oxide per unit of sorbitol.  The fatty acid composition is heterogeneous with oleic acid as major component (min. 58 %).

Tween 80 is used as an additive for cell culture media. It has numerous effects, e.g. increasing the transformation frequency of Brevibacterium lactofermentum or enhancing the secretion of acid and alkaline phosphatase by Neurospora crassa.

This detergent can be used with particular effect in the biotechnological preparation of microbial enzymes. Tween 80 increases the microbial formation of enzymes like cellulose, ligninase and linamarase significantly.

Tween 80 is a potential solubilizer for relevant pharmaceutical substances like temazepam and allopurinol. It is furthermore frequently used for inactivation of lipd containing viruses.

Tween 80 has also proved useful in the stabilization of the cAMP-dependent protein kinase.

Tween 80  is a registered  trademark of the CRODA International Plc.
