Silicone-substituted cinnamamide/malonamide/malonate compounds and photoprotective compositions comprised thereof

摘要

Novel silicone-substituted cinnamamide/malonamide/malonate compounds having the structural formulae (1) and (2): in which A is a radical of formula (3): are well suited for the photoprotection of human skin and/or hair against the damaging effects of UV-A and UV-B irradiation, particularly solar radiation, and are also useful for photoprotecting such UV-sensitive substrates as plastics.
