Our Span HP range of highly purified sorbitan esters are ideal for use in applications requiring a tighter purity specification than the standard Span grades offer. The Span HP grades have reduced moisture levels, lower peroxide values and lower acid values. 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.
