Find a grade by HLB
Filter the range by emulsion type, HLB window and application field. This narrows the starting point — the final choice still belongs in your lab.
No grade matches that combination. Widen the HLB range, or tell us the system and we will propose a blend.
If nothing fits exactly
A blend of one low-HLB and one high-HLB grade gives a continuously adjustable blend HLB — SPAN 80 with Tween 80 covers everything from 4.3 to 15.0. We can also shift a grade's own HLB, viscosity or acid value.
