Sorbitan Oleate is a nonionic surfactant and emulsifier derived from the esterification of sorbitol with oleic acid. It has a low HLB value, making it particularly effective in stabilizing water-in-oil (W/O) emulsions. Sorbitan Oleate also acts as a dispersing agent and solubilizer for oil-soluble ingredients, and it is often used with polysorbates to create versatile emulsification systems. It is mild, biodegradable, and compatible with a wide range of formulation types.
