Abstract
The effect of a homologous series of octylphenoxy surfactants [2-{α-[4-(1, 1,3,3-tetramethylbutyl)phenoxy]poly(2-ethoxy)}ethanol;«Triton-X» series], with five (TX-45), 9-10 (TX-100), 16 (TX-165) and 40 (TX-405) units of ethylene oxide (EO) on penetration of NAA [2-(1-naphthyl)acetic acid] through enzymatically isolated tomato (Lycopersicon esculentum Mill.) fruit cuticles was investigated. Surfactant effects on NAA flux were related to EO chain length and to surfactant concentration, compared on a basis relative to the critical micelle concentration (CMC, 2.5×CMC and CMC/2.5). At concentrations above the CMC, TX-45 and TX-100 increased NAA flux 2.5 and 1.5-fold, respectively, while TX-165 was without effect and TX-405 decreased NAA flux 0.7-fold
