The partitioning of 1-propanol, 2-propanol, 1-butanol, 2-butanol, 2-methyl-2-propanol, 1-butylurea, tert-butylurea, cyclohexanol, 6-caprolactam, 1-hexanol, 1-octanol, and 1-decanol between the micelles of dodecyl- (C{sub 12}), tetradecyl- (C{sub 14}), and hexadecyl-(C{sub 16}) trimethylammonium bromides and the surrounding aqueous phase has been determined at 25{degree}C. It is found that the ability to depress the critical micelle concentration, the corresponding ability to increase the micellar degree of ionization, and the coaggregation (solubilization) tendency all tend to decrease with increasing surfactant chain length.
