General description

Span 20 is a co-surfactant.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product is 100% bio-based non-ionic surfactant, thus aligns with "Use of Renewable Feedstocks" and belongs to "12 principles aligned" category of our greener alternatives.

Application

Span 20 has been used in a study to assess enhanced solubility and oral bioavailability of itraconazole. It has also been used in a study to investigate the oxidation of unsaturated lipids in oil-in-water emulsions.

Other Notes

Fatty acid composition: Lauric acid (C12:0) ≥ 44%; balance primarily myristic (C14:0), palmitic (C16:0) and linolenic (C18:3) acids.
