A delivery system that includes surfactant micelles, and a surfactant system of nonionic, cationic or zwitterionic surfactants, with the surfactant being present in an amount equal to or greater than its critical micelle concentration, 10% or more by weight, based on the total weight of the delivery system, of a hydrophilic phase formed of water and/or a water-soluble solvent, and from 0.0001 to 5% by weight, based on the total weight of the delivery system, of a compound having the structureor salts, and/or solvates thereof (“compound 1”), wherein at least a proportion of compound 1 is encapsulated within the surfactant micelles.
