Abstract: The authors used kinetic experiments to track the heat-induced decomposition of disodium lauryl-sulfosuccinate during the manufacture of soap bars and compared the results with those of another soap surfactant, sodium cocoylisethionate.

Sulfosuccinates as a class of surfactants are very versatile materials, and are used industrially for a range of products and functions. Sulfosuccinates are synthesized by a reaction of maleic anhydride or an unsaturated dibasic acid anhydride with alcohols or any compound with a hydroxyl group. The maleic monoester or diester formed is then sulfonated with sodium sulfite/bisulfite for form alkyl or dialkyl sulfosuccinates, respectively, as shown in Figure 1.
