Normal micelles in non-aqueous media

Micellization of both ionic and non-ionic surfactants occurs in solvents such as 

2-diols, triols, and formamide which have sufficient hydrogen bonding centers that 

Carbocation or oxonium ion derived micelles form in concentrated sulfuric acid, a medium which is unsuitable for most organic solutes [20], They are generated by dissolving the ether or alkene in sulfuric acid  

The effects of a variety of added organic solvents upon the thermodynamics of micellization have been investigated by lonescu and Fung [129], 

Aggregation of surfactants in apolar solvents, e.g., aliphatic or aromatic hydrocarbons, occurs provided that small amounts of water are present [1,126,127], These aggregates are often called reverse micelles, although the solutions do not always appear to have a critical micelle concentration, and surfactant association is often governed by a multiple equilibrium, mass action, model vith a large spread of aggregate sizes [130,131], It has recently been suggested that the existence of a monomer f -mer equilibrium should be used as a criterion of micellization, and that this term should not be applied to self-associated systems which involve multiple equilibria [132],
