摘要:
Chelating agents for a transition metal, which exhibit the special feature of being photocleavable, that is containing a chelating functional group blocked by a photocleavable protecting group such that the chelating functional group is released only on exposure to luminous, specially ultraviolet, radiation, trap the transition metals released by the action of the luminous radiation, without exhibiting the side effects observed with conventional chelating agents. Compositions, especially cosmetic and/or dermatological ones, containing at least one such chelating agent are useful for protecting the skin, the mucosa, and/or the hair against ultraviolet radiation.
