Narrow distribution alcohol ether carboxylate (NAEC9) synthesized by oxidation was compounded with ammonium lauryl ether sulfate (ALES), hexadecyl trimethylammonium chloride (1631) and octadecyl glucoside (APG0810), the effects of different mass fractions of NAEC9 on the surface tension、foamability、wetting、emulsification and decontamination of the composite system were studied. The results show that the NAEC9/1631 mixed system was obvious synergistic effect in surface tension、foam and wettability, and the synergistic effect was strongest when the mass fraction of NAEC9 was 66.7 %, the wetting time decreased from non-wetting to 37 s, and the foam volume reached a maximum of 500 mL at 30 s. However, no obvious synergistic effect was found between NAEC9/ALES and NAEC9/APG0810 system . In terms of decontamination performance, the NAEC9/ALES mixed system has the best decontamination performance for sebum decontamination cloth and the worst decontamination ability for protein decontamination cloth. The compound of anionic surfactant NAEC9 and cationic surfactant 1631 has a good synergistic effect, and the surface activity is enhanced without precipitating.
