Abstract

La présente invention concerne des produits de nettoyage liquides, contenant des phosphates, pauvres en eau à exempts d'eau, en particulier un produit de lavage de vaisselle en machine, qui contient au moins un composant d'adjuvant contenant des phosphates, de préférence un polyphosphate, des ions de potassium et de sodium et au moins un alcool polyvalent, choisi parmi le glycérol et des mélanges de glycérol et de 1,2-propylèneglycol et qui présente une teneur en eau inférieure à 25 % en poids. Selon l'invention, le rapport massique de glycérol à 1,2-propylèneglycol est de 1:1 ou plus, de préférence de 2:1 ou plus et le rapport massique des ions de potassium aux ions de sodium dans le produit de nettoyage est soit de 2:1 ou plus, soit de 1,5:1 ou moins. Des procédés pour leur préparation et leur utilisation sont également décrits.
