Abstract

La présente invention porte sur une composition et un procédé pour le traitement de substrats, tels que des tissus ; en particulier pour un détachage amélioré et un meilleur nettoyage lors du lavage subséquent et également pour une redépôt réduite de la saleté. La présente invention a par conséquent pour objet d'assurer un détachage aqueux/javellisable, huileux ou particulaire amélioré. La présente invention a pour autre objet d'assurer un nettoyage amélioré lors du lavage subséquent et de réduire la redépôt de la saleté. Il a été découvert qu'un détachage aqueux/javellisable, huileux ou particulaire amélioré et une redépôt réduite de la saleté peuvent être réalisés par dépôt sur le tissu d'un complexe de tensioactifs constitué d'un tensioactif anionique et d'un tensioactif cationique, d'un polymère non ionique et d'un agent chélateur.
