| Abstract: | Anionic and nonionic surfactants exhibit opposite changes in hydrophilicity with a change of temperature. This antagonism can be harnessed by the use of mixtures. The phase behavior and emulsion type are mapped on a temperature water-oil/ratio diagram for different anionic-nonionic mixtures. It is shown that the mixing can result in insensitivity to temperature of different kinds of emulsions. |
