“…Corroborating the results obtained with FTIR [3,25,34,38,39], the DSC peak corresponding to the 'fusion' was not observed at low SL values because the adsorbed surfactant presented a liquid-like arrangement, i.e., a 'molten' state. On the other hand, at a SL >1 the adsorbed surfactant presented a solid-like arrangement and hence it showed the 'fusion' peak at the corresponding temperature in the DSC curve.…”
