Title (EN) COLOR CHANGING GELS AND METHOD OF PRODUCTION
(FR) GELS À CHANGEMENT DE COULEUR ET LEUR PROCÉDÉ DE PRODUCTION
Abstract:
(EN) An aqueous system comprises a pH-responsive visual indicator and a volatile pH modifier. A method of producing a visual signal comprises evaporation of a volatile pH modifier from a system further comprising a pH-responsive visual indicator.
(FR) Un système aqueux comprend un indicateur visuel sensible au pH et un modificateur de pH volatil. Un procédé de production d'un signal visuel comprend l'évaporation d'un modificateur de pH volatil à partir d'un système comprenant en outre un indicateur visuel sensible au pH.
