Reversible switchable surfactants are provided. A surfactant is the salt of an amidine or guanidine having at least one R group that is a hydrophobic moiety selected from the group consisting of higher aliphatic moiety, higher siloxyl moiety, higher aliphatic / siloxyl moiety, aliphatic / aryl moiety, siloxyl / aryl moiety, and aliphatic / siloxyl / aryl moiety. The other R groups are smaller moieties such as H, C1 to C4 aliphatic or the like. The surfactant is turned on by a gas that liberates hydrogen ions, such as, for example, carbon dioxide, which liberates hydrogen ions in the presence of water. The surfactant is turned off by exposure to a flushing gas and / or heating. When “on” the surfactants are useful to stabilize emulsions, and when “off” they are useful to separate immiscible liquids or a liquid and a solid. The surfactants find uses in polymerization and in the oil industry.
