十二烷基甲基二羟乙基溴化铵的应用性能测定

Determination of Application Performance of Dodecylmethyldihydroxyethyl Ammonium Bromide

测定了十二烷基甲基二羟乙基溴化铵的应用性能。其CMC值为1.67×10-4mol/L,表面张力为24.2N/m,Krafft点小于0℃。其增溶性能、再润湿力很好,有较好的乳化性能、发泡力和柔软性能,以及其对织物白度的影响较小。

The application performance of dodecylmethyldihydroxyethyl ammonium chloride （DBMAC） was tested in this paper. The CMC was 1.67×10^-4mol/L,surface tension was 24.2 N/re,and Krafft point was below 0℃. At the same time,it showed the good solubilization and deuto-wetting property of the surfactant. Its emulsification property, foaming power and softening property were also quite ratio factory. Furthermore the effect on the fabric whiteness was lower.
