The reaction of surfactant radicals and the spin trap 2-methyl-2-nitrosopropane has been investigated. Sodium dodecyl sulfate and sodium octyl sulfate show no spin adduct when surfactant and spin trap are irradiated with /sup 60/Co at concentrations below their critical micelle concentration (CMC). At concentrations above the cmc a nitroxide is formed from the reaction of the trap and a secondary surfactant radical produced via hydroxyl radical attack on the hydrocarbon chain. The micellar catalytic effect and the site of hydroxyl radical attack are discussed.
