説明
The telomer-type surfactants containing carbamoyl and/or carboxyl group that had been prepared in the previous paper were evaluated as detergent builder.<BR>The detergent solution composed of LAS, builders and Ls-CONH2 telomer, which telomerized l-dodecanethiol with acrylamide, with only carbamoyl group showed more excellent values than that of STPP for Ca2+ sequestration, CaCO3 dispersion ability, orange OT solubilization ability and detergency, and these values were increased with increasing the hardness of used water. This activation was attributed to the mixed micelle formed by LAS with Ls-CONH2.<BR>On the effect of carboxyl group in the telomer, chelating value, lime soap dispersion power, orange OT solubilization ability, anti-redeposition ability and detergency decreased with increasing the content of carboxyl group and displayed a minimum at 1020 mol% carboxyl group content. On the other hand, CaCO3 dispersion ability increased by introduction of carboxyl group and the maximal value obtained at 20mol% carboxyl group content. These were interpreted as a result of interaction between carbamoyl and carboxyl groups in telomer aqueous solution and resulted variation of conformation of dissolved telomer chain.
