Title (EN) IMPROVED PSEUDOCATALASE COMPOSITION
(FR) COMPOSITION DE PSEUDOCATALASE AMELIOREE
Abstract:
(EN) The $i(in vivo) catalytic dismutation of hydrogen peroxide by the pseudocatalase such as a transition metal bicarbonate complex is increased by the addition of a chelating agent, preferably EDTA, citic acid, 2,6-pyridinedicarboxylic acid, or a salt thereof. Further, the stability of a topical composition comprising a transition metal bicarbonate complex is improved by storing the composition under carbon dioxide, preferably under pressure in aerosol form.
(FR) La dismutation catalytique $i(in vivo) du peroxyde d'hydrogène par une pseudocatalase, du type complexe de métal de transition et de bicarbonate, est augmentée par l'addition d'un chélatant, de préférence l'EDTA, l'acide citrique, l'acide 2,6-pyridinedicarboxylique ou de leurs sels. En outre, la stabilité d'une composition à usage local comprenant un complexe de métal de transition et de bicarbonate est améliorée en conservant la composition sous gaz carbonique, de préférence sous pression dans une bombe aérosol.
