Abstract

Appareil reproduisant les phénomènes de sudation ou d'échange chimique d'une peau vivante; phénomènes qui peuvent être modifiés par l'application de produits cosmetologiques. Cette modification appréciée par une mesure permet de comparer l'efficacité de différents produits cosmétologiques entre eux. L'appareillage comporte : - une membrane synthétique ou un tissu animal polarisé électriquement et maintenus hydratés par un gel; - une cellule d'électrolyse thermostatée comportant une cathode et une sonde, l'anode étant solidaire de la membrane; - un électrolyte maintenu sous une faible pression à l'intérieur de la cellule; - un dispositif électrique permettant de mesurer les variations d'impédance des membranes; - l'appareillage peut être utilisé pour apprécier l'efficacité ou l'altération d'un produit cosmétique destine à l'hygiène de la peau.
