Abstract

L'invention porte sur un matériau désodorisant qui, lorsqu'il est utilisé dans un habitacle de véhicule automobile classique, et notamment dans un habitacle de véhicule équipé d'un conditionneur d'air, apporte un effet désodorisant stable en raison du fait qu'il se vaporise sur une longue période de temps et, de plus, n'a aucun effet secondaire sur le circuit de conditionnement d'air. Le matériau désodorisant possède des propriétés de vaporisation entretenues et est destiné à être utilisé dans des véhicules, et il comprend une feuille fibreuse imprégnée, en tant qu'ingrédient actif, par au moins un composé antimicrobien à base de phénol comportant dans sa structure moléculaire un groupe hydroxyle se liant facilement à des sources de mauvaises odeurs telles que les amines.
