Scheme of possible SLES cleavage mechanisms for complete degradation to CO2 and biomass formation. The general molecular structure of SLES is shown, where n is the mean of ethoxy units (n = 2–3 in commercial products), and R is the alkyl group (the linear alkyl chain of AES surfactants can have 12 to 18 carbons) (adapted from Hales et al. (1986) and Steber and Berger (1995))
