Span 60 (Sorbitan Stearate) – Non-Ionic Emulsifier for Creams & Balms
Span 60, also known by its INCI name Sorbitan Stearate, is a nonionic lipophilic emulsifier widely used in cosmetic and personal care formulations. With an HLB value of approximately 4.7, Span 60 is the preferred choice for creating stable water-in-oil emulsions such as cold creams, body butters, protective balms, and thick ointments. It works by reducing interfacial tension between oil and water phases, producing smooth and consistent textures. Sorbitan Stearate also functions as a co-emulsifier when paired with polysorbates like Tween 60 to build versatile O/W systems across a wider HLB range. It offers excellent thickening support, enhances product stability during temperature fluctuations, and contributes a luxurious skin feel without greasiness. Derived from the esterification of sorbitol with stearic acid, Span 60 is suitable for natural and conventional formulations alike. Rabibazaar supplies cosmetic-grade Span 60 for DIY beauty formulators, soap makers, and professional cosmetic manufacturers across Pakistan.
