A composition containing: at least one organic phospholipid capable of forming bilayers in aqueous solution; at least one amphoteric surfactant; at least one non-ionic surfactant present in an amount by weight equal to - or greater than - the amount of the phospholipid; and a water insoluble polymer, comprising at least one aromatic monomeric residue, wherein said aromatic monomeric residue comprises at least one aromatic unit substituted with at least one hydroxyl group. This also relates to a delivery system for water-insoluble ingredients containing the above components and an aqueous phase, where the organic phospholipid, the amphoteric surfactant and the non-ionic surfactant are present in a combined amount sufficient to allow the polymer Water insoluble be incorporated into the system. A method for the treatment of a keratinous substance is also disclosed. |
