Title (EN) EXTENDING EFFECTIVE LIFE OF RAZOR BLADES BY FACTOR OF 5-7
(FR) EXTENSION DE LA DURÉE DE VIE RÉELLE DE LAMES DE RASOIR D'UN FACTEUR 5-7
Abstract: front page image
(EN)This disclosure dramatically extends by a factor of 5 to 7, the effective service-life of steel shaving blades by chelating mineral molecules in common tap water, thus preventing them from accumulating and attaching to the blade surfaces. This method uses citric acid and common tap water but in specific ratios and steps in its preparation and use.
(FR)L'invention permet de prolonger considérablement d'un facteur de 5 à 7 la durée de vie en service réelle de lames de rasoir en acier, par chélation des molécules minérales présentes dans l'eau du robinet habituelle, ce qui les empêche de s'accumuler et de se fixer sur les surfaces des lames. Ce procédé utilise de l'acide citrique et l'eau du robinet habituelle, mais dans des proportions et selon des étapes spécifiques lors de la préparation et de l'utilisation.
