Detergency performance comparisons of dodecyl‐type LAS and ABS show that at typical conditions for countries in Latin America, Africa, the Middle East and Southeast Asia, LAS gives better cleaning performance than ABS. The differences in carbon chain distribution between dodecyl‐type LAS and ABS account for some of the improvement in performance. An additional factor is the solubility of the calcium sulfonate salts. At high use level wash conditions, LAS is less hardness‐sensitive than ABS. This increase in Ca +2 tolerance by LAS can result in improved cost/performance of HDP formulations.
