SPAN 80

Sorbitan Monooleate — grade VS-201A · CAS 1338-43-8

HLB 4.3 — W/O emulsifier · scale runs HLB 3 (lipophilic) to 16 (hydrophilic)

Our highest-volume grade and the core W/O emulsifier for emulsion explosives. Strongly lipophilic, stable at the ammonium-nitrate interface, and the same chemistry that serves invert drilling mud and agrochemical EC.
