Polysorbate 80 is a solubilizerwith an HLB of 15; we use it to disperse oils into otherwise watery concoctions. Compared to Polysorbate 20 it is better suited to solubilizing true oils. From Croda: “Polysorbate 80 is an O/W [oil-in-water] emulsifier and dispersant often used in conjunction with the appropriate SPAN. Good solubilizing properties, recommended in systems with unsaturated lipid components such as oleyl alcohol and vegetable triglycerides”.
