Abstract

The magnetized water is known to have a unique pattern of hydrogen bond between water molecules, thereby producing different physicochemical properties from the ordinary water. We have examined the effect of magnetized water on the change of critical micelle concentrations (CMC) of some surfactants. The CMC changes of SDS (sodium dodecyl sulfate) and CTAB (cetyltrimethylammonium bromide) dissolved in the magnetized water have been determined by the conductivity measurement at $25\;{^{\circ}C}$ and that of SDS, CTAB and Pluronic F-68 have also been examined by the surface tension method at $25\;{^{\circ}C}$. The CMC variation of SDS was examined by ITC (Isothermal Titration Calorimeter) at $25\;{^{\circ}C}$. The CMC of SDS, CTAB, and Pluronic F-68 are more decreased in the magnetized water, SDS is about $2.7{\sim}6.5$25 %, CTAB is about $2.3{\sim}3.0$%, and Pluronic F-68 is about 24.2 %, than in the control water.
