A number of studies have determined that non-ionic surfactants are capable of altering diffusionrates and transportation of both water and active ingredients thorough the waxy barrier of variouscrops, manipulating their morphology and structural integrity; however past investigations into the bulk composition of cuticular waxes suggest that charged and zwitterionic surfactants have a minimal effect upon the transportation properties of waxes.Our investigations into the influence of charged surfactants upon ultra-thin nano-films of reconstituted waxes - representative of waxes found upon the surfaces of crops - suggest that these surfactants do have a significant influence upon wax structure and integrity. A neutron study into the interaction of charged surfactants with waxes will allow us understand how surfactants promote the transport of water and active ingredients into crops.
