A new kind of trisiloxane quaternary ammonium salt surfactant (TQAS) was syn-thesized by the ring-opening reaction of epoxy group trisiloxane (ETS) with N ,N ,N′,N′-tetramethylethylene diamine(TMEDA ) .ETS was prepared by hydrosilylation from 1 ,1 ,1 ,3 , 5 ,5 ,5-heptamethyltrisiloxane (HM TS) and allyl glycidyl ether (AGE) in the presence of platinum catalyst .The chemical structure of TQAS was characterized by IR .The interfacial property and foaming property of TQAS were investigated .Experimental results were showed as follows .The critical micelle concentration (cmc) of TQAS solution is 0 .7 g?L-1 . The surface tension (γcmc ) of TQAS solution in cmc is 26 .4 mN?m-1 .The foaming power of 0 .1% TQAS (mass fraction) solution is 2 .20 and foam stability after 5 min is 0 .167 .The bubble that produced by TQAS disappear easily .
