✦ Synopsis

This note reports the effects of low levels of SDS on the phase behaviour of dilute CIZE6 solutions above the cloud point. On raising the temperature the two coexisting liquid phases are replaced by a lamellar phase, which gives way to two further liquid phases at still higher temperatures. A recent publication has assigned an isotropic liquid structure to the lamellar phase.

Aqueous solutions of dodecyl hexaoxyethylene ether (the non-ionic amphiphile CIZE6) with added sodium dodecyl sulfate (SDS) show a closed solubility loop which shrinks progressively as the SDS/C12E6 molar ratio r increases and disappears when r is larger than 0.013. The results are explained by noti
