摘　　要：Cardanol polyoxyethylene ether is a kind of nonionic surfactants based on natural raw materials, with good surface activity and resistance to hard water. At 25 ℃, the value of critical micelle concentration （CMC） is 6.09×10-6 mol/L, and the lowest surface tension （TcMc） is 38.08 mN/m. Moreover, cardanol polyoxyethylene ether has strong salt tolerance to monovalent inorganic salts; with the increase of concentration of divalent inorganic salt, the surface activity of cardanol polyoxyethylene ether is enhanced. The effect of monohydric alcohol on the surface activity of cardanol polyoxyethylene ether is complex： the ability of BGF-10 to form micelles increases and then decreases with the increase of the concentration of monohydric alcohol, cardanol polyoxyethylene ether has a synergistic effect with anionic, nonionic and cationic surfactants, especially with hexadecyltrimethylammonium bromide （CTAB）, and its critical micelle concentration is decreased by 2.52%, while the surface tension is decreased by 11.49%. Test results also show, comparing to nonylphenol polyoxyethylene ether, the emulsifying and the thickening performances of cardanol polyoxyethylene ether are better, and its foam performance is lower. Also, the cloud point of cardanol polyoxyethylene ether is higher than nonylphenol polyoxyethylene ether. In most case, the detergency of cardanol polyoxyethylene ether is better than or equivalent to nonylphenol polyoxyethylene ether. cardanol polyoxyethylene ether is an excellent alternative to nonylphenol polyoxyethylene ether in detergents.Cardanol polyoxyethylene ether is a kind of nonionic surfactants based on natural raw materials, with good surface activity and resistance to hard water.
