Said compositions provide fabric integrity benefits but mitigate the color fidelity problems which may be caused by the use of certain polyamines.

La présente invention se rapporte à la blanchisserie et à des compositions détergentes de blanchisserie. Elle comporte un système de rehaussement de l'aspect des textiles comprenant un ou plusieurs polyamines, et un système de protection du teintage à base de métaux de transition comprenant un oligomère formé par réaction d'un imidazole et d'un agent de réticulation, de préférence l'épichlorohydrine. Ces compositions sont avantageuses pour l'intégrité des textiles et atténuent les problèmes de préservation des couleurs pouvant être causés par l'utilisation de certains polyamines.
