Span 80 nonionic surfactant

nonionic surfactant used was sorbitan monooleate or better known as Span 80 Span 80 was used because it has a long alkyl chain which was expected to form a vesicle that was thicker to protect the active substance that was very easily oxidized The concentration of surfactant used for manufacturing niosomes mol was the range of 100 - 300 mol 34 13 000 ng/L while the nonionic surfactants including Span 80 Tween 80 Tween 85 were 35 detected infrequently (26% of samples) at concentrations from 840 – 9100 ng/L The 36 enantiomers α-/β-EHSS were detected in seawater at concentrations from 200 – 1 900 ng/L and

Span 80 is a nonionic surfactant Application Span 80 has been used in a study to assess transfersomes as a transdermal delivery system for sertraline It has also been used in a study to investigate the dominant factors affecting the stability of nanoemulsions

Nonionic surfactants are the most common type of surface active agent used in preparing vesicles due to the superior benefits they impart with respect to stability compatibility and Span 80 ratio of 1:310 although high encapsulation of colchicine and 5-flourouracil was reported in niosomes made with a

commonly used nonionic surfactants include: • Triton X-100 • Igepal CA-630 • TWEEN 20 and TWEEN 80 • Span 20 and Span 80 All of these surfactants should be used at very low concentration in order to avoid bubble formation A recommended practice is to dilute the surfactant to 1 – 10 volume % using filtered DI water Place the

Spans and Tweens are extremely mild but very powerful multi-functional nonionic surfactants SPAN HP is a range of sorbitan fatty acid esters while TWEEN HP is a range of polyoxyethylene sorbitan fatty acid esters (polysorbates) Both ranges can be used in a multitude of pharmaceutical applications particularly when additional purity is needed

Nonionic surfactants These surfactants do not bear an electrical charge and are often used together with anionic surfactants An advantage is that they do not interact with calcium and magnesium ions in hard water They account for nearly 50% of surfactant production (excluding soap)
