Premicellar aggregates aggregation number

There are also surfactants which display monomer h-mer association in nonpolar solvents [12,14] they often contain two hydrocarbon tails. Dialkyl sulfosucci-nates [15-22], dinonylnaphthalenesulfonates [23, 24] and phosphatidylcholines [25-31] are perhaps the most extensively studied. Aggregation numbers typically range from 12 to about 30, but dodecylammonium benzoate forms a trimer in a monomer h-mer association [32]. Even with these surfactants, the definition of a CMC is not without ambiguity. Thus in the case of Aerosol OT (sodium di(2-ethylhexyl) sulfosuccinate, AOT) [33-36], a premicellar linear trimer which undergoes a conformational transition to a closed trimeric unit has been implicated. [Pg.199]
