Effects of Surfactants on Cuticular Barrier Properties
The permeation of the cuticle plays an important role in the application of herbicides to crops as the active ingredient has to diffuse through the cuticle to reach its destination. Surfactants are usually added to herbicide formulations to improve the efficacy of the agrochemicals. The permeability of organic compounds through cuticles has been shown to be correlated with the permeance of water. Thus, studies on water permeability through cuticles will help to gain insights in the permeability of active ingredients. In this study Brij 30 was tested for its effect on water permeation through cuticles. The rates of transpiration of water increased after the application of Brij 30 by a factor of 25. Brij 30 is a polydisperse alcohol ethoxylate and the biochemical analysis of Brij 30 revealed that it is a complex mixture of different monomers. Mechanisms for the enhancement for cuticular permeation by surfactants are discussed.
