Abstract:
The present invention relates to cosmetic preparations for protection of the human skin and human hair against the harmful effects of ultraviolet solar radiation containing the water soluble UVA absorbing substance disodium phenyl dibenzimidazole tetrasulfonate [2,2'-(1,4-Phenylene)bis(1H-benzimidazole-4,6- disulfonic acid, monosodium salt); 1H-Benzimidazole-4,6-Disulfonic Acid, 2,2'- (1,4-Phenylene)Bis-, Disodium Salt] together with Benzophenone-4 (2-Hydroxy- 4-methoxybenzophenone-5-sulfonic acid) and its salts to quench the fluorescence of disodium phenyl dibenzimidazole tetrasulfonate.
Abstract:
The present invention relates to cosmetic preparations for protection of the human skin and human hair against the harmful effects of ultraviolet solar radiation containing the water soluble UVA absorbing substance disodium phenyl dibenzimidazole tetrasulfonate together with troxerutin to quench the fluorescence of disodium phenyl dibenzimidazole tetrasulfonate, and corresponding methods of manufacturing such preparations and uses of troxerutin and disodium phenyl dibenzimidazole tetrasulfonate.
Abstract:
The invention concerns preparations, particularly cosmetic or pharmaceutical/dermatological preparations, containing phenylbenzimidazole sulfonic acid (i.e. 2-phenylbenzimidazole-5-sulfonic acid) neutralised with basic amino acids such as arginine, lysine, ornithine and histidine so that the pH of the preparation can be at or below 7.0 without incurring crystallisation of the phenylbenzimidazole sulfonic acid.
Abstract:
Beschrieben wird die Verwendung einer Verbindung der Formel (I) als UV-Filter in kosmetischen Formulierungen, insbesondere in Kombination mit UV-Filtern aus der Gruppe der Methoxycinnamat-Derivate und/oder Dibenzoylmethan-Derivate.
Abstract:
Die vorliegende Erfindung betrifft lichtstabile kosmetische oder dermatologische Lichtschutzzubereitungen mit mindestens einer Lipidphase und mindestens einer wässrigen Phase dadurch gekennzeichnet, dass diese a) mindestens einen auf Dibenzoylmethanderivaten basierenden UV-A Sonnenschutzfilter, b) mindestens einen ein- oder mehrfach sulfonierten und als Salz wasserlöslichen UV-A Sonnenschutzfilter und c) mindestens ein Naphthalindicarbonsäurederivat enthalten, ein Verfahren zur Stabilisierung von Dibenzoylmethanderivaten sowie die Verwendung der Lichtschutzzubereitungen zum Schutz der Haut und der Haare vor UV-Strahlen.
Abstract:
The inventive 2-hydrazino-1,3-heteroazoles or salts thereof are, as very good tyrosinase inhibitors, active constituents in topical cosmetic agents, especially in cosmetic or dermatological skin brightening agents.

Abstract:
The invention relates to 3,4-dihydroxybenzyl-substituted carbonic acid derivatives, to their production, and to their use as antioxidants or free-radical scavengers, especially in cosmetic and pharmaceutical preparations and in foodstuffs and stimulants, to protect cells and tissues from the harmful effects of radicals and reactive oxygen compounds that accelerate aging. The invention further relates to cosmetic and pharmaceutical preparations and to foodstuffs and stimulants that comprises the inventive 3,4-dihydroxybenzyl-substituted carbonic acid derivatives.
