Preferred Label : micellar catalysis;
IUPAC definition : The acceleration of a chemical reaction in solution by the addition of a surfactant
at a concentration higher than its critical micelle concentration so that the reaction
can proceed in the environment of surfactant aggregates (micelles). (Rate enhancements
may be due, for example, to higher concentration of the reactants in that environment,
more favourable orientation and solvation of the species, or enhanced rate constants
in the micellar pseudophase of the surfactant aggregate.) Micelle formation can also
lead to a decreased reaction rate.;
