Extended型表面活性剂微乳液用于低温洗涤

Application of Extended Surfactant Microemulsion for Detergency at Low Temperature

Extended型表面活性剂以其独特的聚氧丙烯嵌段结构使得疏水尾基得以延伸到油相中,同时不牺牲其水溶性。这种表面活性剂可以与油脂之间形成超低界面张力,并且可在常温下形成无醇微乳液,通过显著降低界面张力而使织物油污在低温下被去除,因此,显示出其在日常低温洗涤中的潜力。

With its unique polypropylene oxide(PPO)block structure,Extended surfactant(e-surfactant)allows the hydrophobic tail group to extend into the oil phase without sacrificing its water solubility.E-surfactant can form ultralow interfacial tension(IFT)with oil and can form alcohol-free microemulsion at room temperature.The microemulsion formulation is another optimized form to reduce IFT and improve the oil removal capacity of fabrics.Therefore,e-surfactant microemulsion has attracted much attention in the field of detergents and is expected to be applied in daily low-temperature washing.
