General description

Span® 60 is a sorbitan monoester than is used as a non-ionic detergent.

Application

Span® 60 has been used in a study to assess encapsulation of doxorubicin in niosomes as a route to tumor targeting. It has also been used in a study to investigate the use of nonionic surfactants as contrast agents for use in diagnostic ultrasounds.

Other Notes

Fatty acid composition: Stearic acid (C18:0) approx. 50%; balance primarily palmitic acid (C16:0).
