摘要:
The present invention relates to novel cosmetic and/or dermatological compositions comprising, in a cosmetically and/or dermatologically acceptable support, i) a dibenzoylmethane derivative, in particular 4-tert-butyl-4'-methoxydibenzoylmethane, ii) at least one specific 1,3,5-triazine derivative, and iii) at least one amide compound. These compositions are particularly photostable. The invention also relates to the use of these compositions in the cosmetic and/or dermatological fields, in particular, as a sunscreen.
摘要:
Topically applicable, water-resistant cosmetic/dermatological emulsions well suited for the UV-photoprotection of human skin and/or hair contain an effective UV-photoprotecting amount of at least one micronized organic UV-screening agent insoluble therein, the mean particle size of such micronized particles ranging from 0.01 to 2 &mgr;m, and further containing at least one associative polymer which is characteristically other than a C8-C16 alkyl polyglucoside.
摘要:
The UV-stability of the UV-photoprotecting dibenzoylmethane compounds is conspicuously enhanced, as is the UV-stability of cosmetic/dermatological sunscreen compositions comprised thereof, by formulating such dibenzoylmethane compounds with an effective UV-photostabilizing amount of at least one micronized insoluble organic UV-screening agent, the mean particle size of said micronized particles ranging from 0.01 to 2 &mgr;m.
摘要:
Topically applicable, water-resistant but emulsifier-free cosmetic/dermatological emulsions well suited for the UV-photoprotection of human skin and/or hair contain (a) at least one aqueous phase and (b) at least one fatty phase, (c) an effective UV-photoprotecting amount of at least one micronized organic UV-screening agent insoluble therein, the mean particle size of such micronized particles ranging from 0.01 to 2 &mgr;m and (d) optionally, at least one crosslinked polymer of at least one ethylenically unsaturated monomer.
摘要:
Topically applicable sunscreen/cosmetic compositions well suited for enhanced photoprotection of human skin and/or hair against the damaging effects of UV-A and UV-B irradiation, particularly solar radiation, comprise a photoprotecting synergistically effective amount of (i) 1,4-benzene �di(3-methylidene-10-camphosulfonic)! acid, optionally either partially or totally neutralized, together with a photoprotecting synergistically effective amount of (ii) a benzotriazole-substituted polyorganosiloxane, in a cosmetically acceptable vehicle, diluent or carrier therefor.
