Trilinear plots showing the performance of linear alkylbenzene (LAS), alcohol ether sulfate (ES) and alcohol sulfate (AS) mixtures are used to optimize surfactant active composition for maximum cold‐water detergency. Superimposition of cost lines allows for estimating cost/performance. Results show that the composition of the optimally performing LAS/ES/AS mixture depends strongly on temperature, water hardness and cloth type. Under most conditions at low water hardness levels, optimum cost/performance is obtained by an all‐LAS active composition. When water hardness exceeds the hardness removal capability of the builder, an LAS/ES blend is best.
