    摘要: Cosmetic materials, e.g., sunscreen agents are encapsulated by means of a compound of the formula (I) where X is O or NR5; EWG is an electron-withdrawing group; R1, R2, R3, R5 are equal to an H, alykl, cycloalkyl, aryl, or heterocyclic group; or R1, R2 and R5 or R1, R2 and R3 together form a heterocyclic group; and wherein at least one NH or NH2 group, attached to an electron-attracting atom or to an atom that is connected to electron-attracting atom or group such as oxygen, nitrogen and sulphur, is present.
