PEG-100 Stearate

Overview

PEG-100 Stearate is a highly versatile and widely utilized polyethylene glycol ester of stearic acid, specifically an ethoxylated fatty acid. Chemically, it is formed by the esterification of stearic acid with polyethylene glycol that has an average of 100 ethylene oxide units. This nonionic surfactant (CAS No: 9004-99-3; INCI: PEG-100 Stearate) stands out in the chemical industry for its exceptional emulsifying, solubilizing, and stabilizing properties, particularly in oil-in-water (O/W) systems. Its high HLB (Hydrophilic-Lipophilic Balance) value, typically around 18.8, signifies its strong affinity for the aqueous phase, making it an indispensable component for creating stable and aesthetically pleasing formulations.
