Sodium Lauryl Ether Sulfate 70% (SLES-70%) is one of the most widely used anionic surfactants. Owing to its excellent detergency, emulsifying, foaming, and degreasing performance, it is extensively used in a wide range of personal care, cosmetic, and detergent formulations. This material is readily soluble in water and can be easily thickened with salt, reducing the need for additional viscosity modifiers in formulations.
