Abstract

La présente invention concerne des compositions de nettoyage liquides à structure lamellaire. Ces compositions comprennent 5 à 50 % d'un système tensioactif, comprenant (a) un anionique ou un mélange d'anioniques et (b) un tensioactif anionique amphotérique et/ou bipolaire en mélange, et l'alkylamphoacétate de métal alcalin comprend 25 à 90 % du composant (b). L'invention traite aussi d'un procédé pour augmenter la stabilité à basse température de ces compositions de nettoyage liquides à structure lamellaire par la sélection d'un alkylamphoacétate de métal alcalin à raison de 25 à 90 % du composant (b). On obtient ainsi une excellente stabilité à basse température.
