Pingpingjia O-10, whose full chemical name is fatty alcohol polyoxyethylene (10) ether, is a nonionic surfactant produced by the addition polymerization of C12-14 fatty alcohol with 10 mol of ethylene oxide (EO). At room temperature, it appears as a white to pale yellow paste with a melting point of about 25°C and an active content of ≥99%. Its molecular structure contains both hydrophilic polyoxyethylene chains and lipophilic fatty hydrocarbon chains, providing balanced surface activity, making it a multifunctional auxiliary agent commonly used in industrial formulations.
The core advantages of this product include: excellent emulsifying ability for various oil-phase substances, forming fine and stable emulsions suitable for oil-in-water (O\/W) emulsification systems; effectively reducing liquid surface tension (about 32 mN\/m), quickly wetting the surfaces of various substrates; and significant dispersing and anti-settling effects on solid particles and hydrophobic substances. Additionally, Pingpingjia O-10 has excellent chemical stability, being resistant to acid, alkali, and hard water. It can be widely compounded with nonionic, anionic, cationic, and amphoteric surfactants for synergistic effects.
As a mature product from Guoli Chemical, Pingpingjia O-10, with its low-foaming characteristics, good solubilizing effect, and reliable batch stability, has become an indispensable basic raw material in many industrial formulations, especially suitable for various process applications in hard water environments.
