Title
(EN) ACTIVATED ALUMINUM/DEPOLYMERIZED ZIRCONIUM ANTIPERSPIRANT COMPOSITIONS
(FR) COMPOSITIONS ANTISUDORIFIQUES D'ALUMINIUM ACTIVE/ZIRCONIUM DEPOLYMERISE
Abstract
(EN) An aluminum-zirconium antiperspirant composition comprising activated aluminum and depolymerized zirconium species is characterized by an Inductively Coupled Plasma (ICO)-Size Exclusion Chromatograpy (SEC)-HPLC method. A good correlation is obtained between the intensity of the zirconium peak at retention time of about 4.3 minutes to about 4.9 minutes by ICP-SEC-HPLC and the extent of the polymerization of the zirconium species, such that the higher the intensity of the zirconium species, the greater the polymerization of the zirconium species. The extent of the polymerization of zirconium species in the activated aluminum-zirconium salt is affected by the factors and reaction conditions such as the ratio of chloride to zirconium in a zirconium hydroxy chloride (ZHC) solution; the heat treatment of the ZHC glycinate solution; and the concentration of activated basic aluminum chloride (BAC) solution. Controlling the reaction conditions yields a novel aluminum-zirconium antiperspirant salt of enhanced efficacy having activated aluminum and depolymerized zirconium species.
(FR) L’invention concerne une composition antisudorifique d’aluminium-zirconium comprenant des espèces d’aluminium activé et zirconium dépolymérisé, qui est caractérisée par une méthode ICP-SEC-HPLC (HPLC d’exclusion - spectrographie couplée à un plasma induit). Une bonne corrélation est obtenue entre l’intensité du pic de zirconium au temps de rétention d’environ 4,3 minutes à environ 4,9 minutes par ICP-SEC-HPLC et l’ampleur de la polymérisation de l’espèce zirconium, de sorte que plus l’intensité de l’espèce zirconium est élevée, plus la polymérisation de l’espèce zirconium est grande. L’ampleur de la polymérisation de l’espèce zirconium dans le sel d’aluminium activé-zirconium est affectée par les facteurs et les conditions de réaction, tels que le rapport chlorure sur zirconium dans une solution d’hydroxychlorure de zirconium (ZHC) ; le traitement thermique de la solution de glycinate de ZHC ; et la concentration de solution de chlorure d’aluminium basique activé (BAC). Le contrôle des conditions de réaction donne un nouveau sel antisudorifique aluminium-zirconium ayant une efficacité accrue contenant des espèces de zirconium dépolymérisé et d’aluminium activé.
