Descripción general

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.

Aplicación

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.

Otras notas

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

The development of lipid oxidation in oil-in-water (O/W) emulsions is widely influenced by the properties of the interfacial layer, which separates the oil and water phases. In this work, the effect of the structure of the interface on the oxidative

Formation of polymeric O/W nano-emulsions has been studied in the water/polyoxyethylene 4 sorbitan monolaurate/ethylcellulose solution system by the phase inversion composition (PIC) method. These nano-emulsions were used for the preparation of nanoparticles by solvent evaporation. Composition variables such as O/S

Non-ionic surfactant-based vesicles (niosomes) composed of non-ionic surfactants (i.e., Tween and Span) and cholesterol were formulated, and their turbidity and particle size assayed. The most appropriate niosomes formulation was mixed with novel synthesized spermine-based cationic lipids to prepare cationic niosomes
