^aCMC was measured via a dye solubilisation method; dye absorbance was plotted against lg (concentration) and the intersection of the best-fit lines drawn for the unimeric and micellar regions gives the CMC (Supplementary Figure S5B). CMC data shown in this table is obtained at 37°C.

^bEnthalpy of micellization is obtained from the gradient of the Arrhenius plot of ln (molar fraction of CMC) against the reciprocal of absolute temperature (Supplementary Figure S5C).

^cGibbs free energy change of micellization is calculated from ln (molar fraction of CMC) using equation 2 at 37°C.

^dEntropy of micellization is calculated from equation 4.

^eSols were prepared at 10 mg ml⁻¹ at room temperature.
