Abstract

The invention relates to topically applicable novel cosmetic / dermatological sunscreen composition, especially suited for the enhanced UV-photoprotection of human skin and / or hair. This composition contains (i) at least a silicone derivative having a benzotriazole functional group as the first shielding agent, (ii) at least a dibenzoylmethane derivative as the second shielding agent, and (iii) at least an amino- substituted 2-hydroxybenzophenone derivative represented by formula (III) as a third shielding agent. The combination of the three UV-screening compounds results in a synergistic effect. The invention also relates to the use of the composition for the photoprotection of the skin and / or hair against the deleterious effects of ultraviolet radiation.

Description

technical field [0001] The present invention relates to novel cosmetic or dermatological compositions for topical application, especially for photoprotection of the skin and / or hair, characterized in that they comprise in cosmetically acceptable excipients: [0002] (i) at least one silicon derivative having a benzotriazole functional group as a first sunscreen; [0003] (ii) at least one dibenzoylmethane derivative as a second sunscreen; [0004] (iii) at least one specific amino-substituted 2-hydroxybenzophenone derivative as a third sunscreen. The protection factor brought about by UV-A PPD However, the combination of these three masking agents resulted in a synergistic effect being obtained. [0005] The invention also relates to their use for protecting the skin and hair from the effects of ultraviolet radiation. Background technique [0006] It is known that light radiation with a wavelength between 280nm and 400nm can brown the human epidermis, and that rays with ...
