Novel s-triazine sunscreens have the structural formula (I):
and are formulated into cosmetic/dermatological photoprotective compositions useful for photoprotecting keratinous substances against the damaging effects of UV-radiation.
Photostable sunscreen compositions containing at least one dibenzoylmethane compound UV-A screening agent and at least one particular s-triazine compound have improved effectiveness with respect to UV-A radiation.
Cosmetic/dermatological sunscreen compositions, suited for photoprotecting, e.g., the skin, lips, scalp and/or hair against the damaging effects of UV-radiation, contain thus effective amounts of at least one novel s-triazine compound tri-substituted with para-aminobenzalmalonate substituents.
