ENCAPSULATED COSMETIC MATERIALS

摘要

Cosmetric materials, e.g., sunscreen agents are encapsulated by means of a compound of the formula (I) where X is O or NR<SUB>5</SUB>; EWG is an electron-withdrawing group; R<SUB>1</SUB>, R<SUB>2</SUB>, R<SUB>3</SUB> R<SUB>5</SUB> are equal to an H, alykl, cycloalkyl, aryl, or heterocyclic group; or R<SUB>1</SUB>, R<SUB>2</SUB> and R<SUB>5</SUB> or R<SUB>1</SUB>, R<SUB>2</SUB> and R<SUB>3</SUB> together form a heterocyclic group; and wherein at least one NH or NH<SUB>2</SUB> 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.
