The influence of alkanes and medium- and long-chain alcohols on the aggregation behavior of ionic surfactants is investigated by fluorescence quenching. The aggregation number of the surfactant is observed to increase dramatically upon addition of alkanes. The influence of added alcohols, however, depends on the chain length. Except butanol, which decreases the size of the aggregate, addition of higher alcohols (from heptanol to decanol) leads to an increase of the size of the micellar aggregate. Addition of alcohols (from butanol to decanol) leads to an expansion of the hydrophobic region of the aggregate and to a promotion of the diffusion process in the interface of the aggregate.
