Abstract

Measurements of density and viscosity for the aqueous solutions of the nonionic surfactants, Triton X-114 and Tween 80, have been taken in the temperature range T = 293–318 K at an interval of 5 K. On the basis of the obtained results, various parameters have been calculated and analyzed including concentration of surfactants in the bulk phase and temperature, for example volume expansivity and fractional free volume, which indicates that water around the Tween 80 molecules is more loosely bound than the Triton X-114. Moreover, it was proved that depending on the temperature and concentration of studied surfactants they can behave as a water structure breaker or maker.
