Abstract
Disclosed is the use of an effective photo-stabilizing amount of stabilizing agent (a) selected from a diphenylacrylate UV filter (a1), a benzylidene amphor derivative (a2), an organosiloxane comprising benzalemalonate groups (a3), a fluoren derivative (a4), and a naphthalene dicarboxylic acid derivative (a5) for improving the stability with respect to UV radiation of a cosmetic or dermatological composition comprising a UV filter combination of at least one dibenzoylmethane derivative (b) and of at least one specific amino-substituted 2-hydroxybenzophenone derivative (c).

Use of an effective photo-stabilizing amount of a stabilizing agent (a) selected from
- a diphenylacrylate UV filter (a1),
- a benzylidene camphor derivative (a2),
- an organosiloxane comprising benzalemalonate groups (a3),
- a fluoren derivative (a4),
- a naphthalene dicarboxylic acid derivative (a5)
- a natural occurring stabilizer (a6);
- and
- a phenolic antioxidant (a7);
- for improving the stability with respect to UV radiation of a cosmetic or dermatological composition comprising a UV filter combination of at least one dibenzoylmethane derivative (b) and of at least one specific amino-substituted 2-hydroxybenzophenone derivative (c).
Use of the dabilzers (a1)-(a7) for the stabilization of specific amino-substituted 2-hydroxybenzophenone derivative (c).
