    Micellization Studies on Binary Mixture of Methionine with Polyoxyethylene (10) Cetyl Ether (Brij-56) and Polyoxyethylene (20) Cetyl Ether (Brij-58) by B. S. Bhadane, T. J. Patil

    Published 2010-01-01
    “…Considering cloud point as threshold temperature of the solubility, the energetic of clouding process (ΔG0cl, ΔH0cl and ΔS0cl) have been evaluated using “Phase Separation Model" It is found that the overall clouding process is exothermic and ΔH0cl > TΔS0cl indicating that the process of clouding is guided by both enthalpy and entropy. This work supports the conjecture that the cloud point is critical phenomenon rather than the growth of micelles.…”
