摘　　要：植物源油酸是一种利用可再生资源生产的表面活性剂,在液体洗涤剂中有广阔的应用前景。从油酸、脂肪醇聚氧乙烯醚和脂肪醇聚氧乙烯醚硫酸钠及其复配体系的表面张力、发泡力、润湿时间和去污力等性能指标研究的结果表明,油酸具有很好的降泡和增黏作用,尽管其不耐硬水和易氧化的缺点限制了其在洗衣液中的添加量,但植物源油酸通过复配依然是一款适用于液体织物洗涤剂中的表面活性剂原料。Plant-derived oleic acid is a kind of surfactant produced from renewable resources and has a broad application prospect in liquid detergents.The surface tension,foaming power,wetting time and cleaning power of oleic acid,aliphatic alcohol polyoxyethylene ether and aliphatic alcohol polyoxyethylene ether sodium sulfate and their composite systems were studied in this paper.The results indicated that Oleic acid had excellent defoaming and thickening effects.However,its drawbacks of intolerance to hard water and susceptibility to oxidation limited the dosage of oleic acid in laundry detergent.Nonetheless,the plant-derived oleic acid remains a suitable raw material for liquid fabric detergents.
