Span 85 emulsifier chemically known as Sorbitan Oleate, is a low-HLB, oil-soluble nonionic surfactant designed for stable water-in-oil (W/O) emulsions. It is widely used as a co-emulsifier and emulsion promoter in emulsion explosives, with additional applications in pesticide formulations and industrial cosmetics. Span 85 ensures high emulsion stability, uniform droplet distribution, and enhanced formulation performance, making it a trusted choice for demanding industrial processes.

Advantages of emulsion explosives in Industrial Applications
High Emulsion Stability – Prevents droplet coalescence and phase separation, ensuring uniform W/O structure.
Enhanced Detonation Performance – Stabilizes explosive emulsions, improving energy output and reliability.
Optimal Viscosity Control – Maintains flow properties during mixing and pumping.
Long Shelf Life – Maintains consistent performance during extended storage periods.
Versatile Application – Can also serve as a co-emulsifier in pesticide emulsions and cosmetic formulations.
Span 85 is functionally equivalent to Span 80, with the main difference being naming. Span 85 is primarily used in industrial and explosive formulations, whereas Span 80 finds broader application, including food and cosmetic products.
