The full chemical name of OPE-105 is Octylphenol Polyoxyethylene (10.5) Ether, with a molecular formula of C₃₅H₆₄O₁₁.₅ (average) and a molecular weight of approximately 668. The product appears as a colorless to light yellow viscous liquid. It is a nonionic surfactant with excellent fluidity and operability, facilitating precise metering and compounding processing.
This product maintains stable interfacial activity under a wide range of temperature and medium conditions. Its core advantages include: excellent emulsifying ability — it efficiently emulsifies various oil phases and organic solvents, forming fine and stable emulsions; outstanding wetting and penetrating properties — it rapidly reduces surface tension, achieving quick wetting and deep penetration on fabrics, metal surfaces, and porous materials; excellent dispersibility — it provides strong dispersion effects on pigments, fillers, and solid particles; broad chemical tolerance — it remains stable under acidic, alkaline, and hard water conditions, resisting hydrolysis or deactivation; good formulation compatibility — it can be compounded with anionic, cationic, and other nonionic surfactants for synergistic effects.
OPE-105 is easily soluble in water and organic solvents. It is a low-foaming surfactant, particularly suitable for industrial applications requiring rapid foam breaking or low foam control. The product remains chemically stable in acids, alkalis, and hard water, adapting to harsh working conditions.
