Abstract

Cette invention concerne des produits de consommation, comprenant des détergents ou des agents de nettoyage sous forme de capsules à basse teneur en formaldéhydes et/ou exemptes de formaldéhydes, qui sont stables en stockage et empêchent ainsi une contamination du détergent ou de l'agent de nettoyage par le formaldéhyde, dont des micro-capsules, la paroi de la capsule contenant une résine qui est obtenue par réaction d'au moins un alcool aromatique ou d'un éther ou dérivé de celui-ci et d'au moins un composant aldéhydique qui contient au moins deux atomes C par molécule, et éventuellement au moins un polymère de (méth)acrylate, et des adjuvants de détergence et/ou tensioactifs. Le détergent ou les agents de nettoyage selon l'invention permettent, pendant l'application, une libération ciblée et durable des substances actives liquides comme, par exemple, en particulier les senteurs, en direction des objets traités.
