Abstract

L'invention concerne des compositions détergentes particulièrement efficaces dans l'élimination de salissures et de tâches graisseuses/huileuses de substrats tels que des tissus ou de la vaisselle pendant des opérations de nettoyage. Ces compositions contiennent essentiellement un constituant tensioactif comprenant du sarcosinate d'oléoyle et une source hydrosoluble d'ions calcium et/ou magnésium. L'invention concerne également des procédés de lavage de ces substrats ainsi que des procédés de prétraitement de ces derniers à l'aide de ces compositions.
