Span™ 20
Chemical Description
Sorbitan Laurate
Product Description
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 20 finds application in topical preparations. It is soluble in many fatty compositions and solvents and dispersible in water, dilute acids and alkalis. Recommended topical usage levels of 0.5-5%.
