The chemical nature of Peregal O-10 is fatty alcohol polyoxyethylene ether, specifically a condensation product of C12-14 alcohols with ethylene oxide (EO), with an average ethylene oxide addition number of 10 moles. Its CAS number is 68439-49-6, and its systematic name can be written as C12-14 alcohol ethoxylate-10 or C12-14 alcohol polyoxyethylene ether (10 mol EO).
This product is manufactured by using natural or synthetic C12-C14 fatty alcohols as starting materials, which react with ethylene oxide under a catalyst through an addition reaction. In the molecular structure, the hydrophobic alkyl chain (R-) of the fatty alcohol provides lipophilicity, while the polyoxyethylene chain segment (-(CH₂CH₂O)₁₀-H) imparts hydrophilicity. This amphiphilic structure, with one end lipophilic and the other hydrophilic, enables it to effectively reduce the interfacial tension between oil and water, performing various functions such as emulsification, wetting, dispersing, and solubilization.
As a typical non-ionic surfactant, Peregal O-10 does not ionize in aqueous solutions, thus exhibiting good chemical stability, resistance to acids, alkalis, and hard water, and does not form precipitates with metal ions. It can be widely used with anionic, cationic, and amphoteric surfactants for synergistic effects.
