PEG-40 Sorbitan Peroleate
What is PEG-40 Sorbitan Peroleate?
PEG-40 Sorbitan Peroleate is a nonionic surfactant from the ethoxylated sorbitan ester group. It forms by esterifying sorbitol-derived sorbitan with peroleic acid from perilla seed oil, then adding about 40 ethylene oxide molecules for water solubility. This structure features a hydrophobic fatty chain and hydrophilic polyether tail. Primarily used in rinse-off cleansers like shampoos and body washes, plus leave-on emulsions such as lotions and creams. It works by decreasing interfacial tension, allowing oil droplets to disperse evenly in water for stable, creamy textures. As a solubilizer, it disperses fragrances and oils into aqueous bases, creating clear micellar waters and toners. Its surfactant action supports mild foaming and dirt removal while leaving a soft after-feel.
