Span™ 80 pharma

Our Span range of sorbitan esters are widely used as W/O emulsifiers and when used in combination with ethoxylated sorbitan esters (the Tween range) they contribute to the overall stability of O/W emulsions. Manipulation of the Span/Tween ratio produces emulsifying systems of various HLB values, allowing the emulsification of a wide range of oils and waxes. Span 80 is a liquid W/O emulsifier and O/W emulsion stabiliser particularly recommended for use with unsaturated lipid components such as oleyl alcohol or vegetable oils. Extensively used as a wetting agent and dispersant for materials such as zinc oxide, calamine and penicillin in lipophilic pharmaceutical bases. Recommended topical usage levels of 0.5-5%.
