Saponin induced clouding behavior of triton X-100 and methylcellulose

The clouding behaviors of the surfactant p-tert-octylphenoxypolyoxyethylene ether (TX-100) and the water soluble polymer methylcellulose (MC) have been investigated in presence of two saponins, saponin-I (mixture of acaciaside A, acaciaside B, proacaciaside-I, proacaciaside-II, and acaciamine) and saponin-II (mixture of mimusopin and mimusopsin). The saponins have been observed to significantly prevent the clouding of both TX-100 and MC at low concentrations. Besides presenting the cloud points at different concentrations of the saponins, the energetics of the clouding process in terms of the solubilities of TX-100 and MC have also been determined.
