CA 2460663
The present invention relates to a cleaning composition comprising an immiscible liquid system having at least one liquid-liquid interface with an interfacial tension greater than 5 mN/m. The less polar solvent in the system has a carbon chain length of at least 4, or is a silicone with more than 3 SiO units. The composition furthermore comprises from 0.001-20% by weight of a benefit agent such as a fluorescer, a dye transfer inhibitor, a fabric softening agent or an anti-redeposition agent. The compositions provide for an improved delivery and efficacy of the benefit agents in e.g. a fabric cleaning process.
L'invention concerne une composition de nettoyage comprenant un système de liquide immiscible comportant au moins une interface liquide-liquide présentant une tension interfaciale supérieure à 5 mN/m. Le solvant le moins polaire de ce système présente une longueur de chaîne carbonée d'au moins 4 ou est un silicone comportant plus de trois unités SiO. La composition de nettoyage comprend également entre 0,001 et 20 % en poids d'un agent bénéfique tel qu'un agent de fluorescence, un inhibiteur de transfert de colorants, un agent adoucissant de tissus ou un agent d'antiredéposition. Ces compositions permettent d'améliorer la distribution et l'efficacité des agents bénéfiques, par exemple au cours d'un processus de nettoyage de tissus.
