Span 83-LQ-(SG) (Sorbitan Sesquioleate) by Croda is the emulsifier that works quietly in the oil phase, doing the structural work that makes a cream feel luxurious, a lotion stay stable, and an emulsion hold together beautifully over time. A nonionic surfactant from Croda’s trusted Span series, it brings a low HLB value and strong lipophilic character that make it particularly effective in water-in-oil (W/O) systems and as a co-emulsifier in oil-in-water formulations.
Its amber viscous form integrates smoothly into the oil phase, reducing interfacial tension between oil and water and creating the stable, uniform emulsion structure that underpins every well-made cream or lotion. Beyond emulsification, it contributes to texture — adding a smooth, creamy richness that improves spreadability and skin feel. It also aids in solubilizing fragrances, essential oils, and oil-soluble actives, making it a genuinely multi-functional ingredient in the formulator’s toolkit.

Formulation Tips
Add to the oil phase and heat to 70–75°C alongside other oil-phase ingredients before combining with the water phase. For O/W emulsions, pair with a higher HLB emulsifier (such as Tween 80 / Polysorbate 80) to achieve the optimal HLB balance for your system. Particularly effective as a co-emulsifier in complex emulsion systems where stability and texture are both priorities. Works well with silicones, esters, and natural oils.
