a Mean cloud point upon heating the micellar solutions determined using turbidimetry data across from three heating and cooling cycles.
b For micelles with irreversible transitions, the cloud point from the first heating cycle is shown.
c The degree of hysteresis from solutions exhibiting irreversible phase transitions was not determined as the normalized transmittance did not reach 0.5 in the cooling cycle.
d Heated from 10–40 °C.
e Heated from 50–95 °C.
