摘要
Abstract
Surface performance of alkyl ethoxy polyglycosides (AEG050 ) and the influences of different additives on them were examined. Results showed that:at 25 ℃,the value of critical micelle concentration (cmc)achieves 44. 5 mg/L,and the surface tension at cmc (γcmc )achieves 29. 4 mN/m. Besides,it displays rather strong capacity for resistance to hard water. With the increase of concentration of NaCl and/or Na2 SO4 , their surface activity increases. In monohydric alcohol solution of relatively lower concentration,the surface activity of AEG050 also strengthens,but when the monohydric alcohol concentration is relatively higher,their surface activity declines. There is a certain synergetic effect when AEG050 blends with other surfactants, especially cetyltrimethylammonium bromide (CTAB ). In this case,cmc of blend composed of AEG050 and CTAB synergizes as 34. 2% lower,while the surface tension γcmc decreases 4. 1%.关键词
