is often observed for mixed amphiphile systems where wormlike
micelles are present [15,16,18,28]. The decrease after the maximum
can be attributed to either the breaking or branching of micelles
[31], or possibly to the two types of mixed micelle formation due
to the chain length difference between the sugar surfactant and
the fatty acids. Note that the pH values of these aqueous sugar
surfactant and fatty acid solutions were above 3.7.
