Polyglyceryl-2 Sesquicaprylate
What is Polyglyceryl-2 Sesquicaprylate?
Polyglyceryl-2 Sesquicaprylate is a nonionic surfactant produced through esterification of polyglycerol-2 and caprylic acid. Polyglycerol-2 derives from glycerol, often from vegetable oils like soybean or palm, while caprylic acid comes from coconut or palm kernel oil sources. This creates a multifunctional molecule with hydrophilic and lipophilic properties, ideal for cosmetic applications. Primarily used in cleansing formulations, lotions, and creams, it acts as an emulsifying agent by lowering surface tension between oil and water phases. It forms a stabilizing interfacial film around dispersed droplets, preventing coalescence and ensuring product homogeneity throughout shelf life and use. This results in smooth application, consistent texture, and enhanced sensory feel without greasiness. Its mild profile supports incorporation into daily skincare routines, particularly where gentle phase stabilization is needed.
