Impact of different diols/polyols on the phase separation behavior as well as thermodynamic properties of tween 80

Abstract Herein, the cloud points (CPs) of tween 80 (Tw 80) in water/(water + diols [ethanediol, propanediol, and butanediol])/(water + polyols [glucose, fructose, and sorbitol]) systems were measured. For diols‐Tw 80‐water system and polyols‐Tw 80‐water system, the CP values were obtained to reduce gradually with increasing content of diols and polyols at a particular concentration of Tw 80. For a certain concentration of Tw 80 having different contents of diols, the observed ∆ H 0 c , as well as ∆S 0 c values, were negative over the range of concentration of diols studied, and the negative values of ∆ H 0 c and ∆ S 0 c were reduced with the enhancement of the content of diols. The values…
