Abstract

La présente invention concerne des compositions de traitement contre les odeurs désagréables qui contiennent un parfum désodorisant, un adjuvant de solubilisation associé et de l'eau. Ces compositions sont utilisées pour traiter les odeurs indésirables sur un article sans qu'il soit nécessaire de le laver. Le parfum comprend: (a) un acétal ou un hémi-acétal produit par la réaction d'un aldéhyde avec un carbinol, ou (b) un cétal ou un hémi-cétal produit par la réaction d'une cétone avec un carbinol, ou (c) un triacétal cyclique d'un aldéhyde. L'aldéhyde peut être l'aldéhyde hexylcinnamique; l'héliotropine; l'aldéhyde undécylénique; le dodécanal ou un composé de formule (I) (II) ou (III). La cétone est l'hédione; l'ionone méthyle ou un composé tel que (V). Le carbinol est le citronellol; le nérol; le géraniol; le dihydromyrcénol; l'alcool β-phényle éthyle; le tétrahydrolinalool; l'undécavertol ou (IV). Il est véritablement préférable que les compositions contiennent un polymère filmogène, par exemple de l'acétate de polyvinyle et/ou au moins de l'acétate de polyvinyle partiellement hydrolysé. On décrit un procédé qui permet de traiter des articles dégageant une odeur désagréable au moyen de l'application de ces mêmes compositions.
