Abstract

Cette invention concerne une composition détergente granulée et d'une densité élevée, laquelle composition possède d'excellentes qualités de biodégradabilité et de sécurité, ainsi qu'une meilleure détergence. Cette composition comprend, dans des proportions spécifiques, (a) un tensioactif à base d'oxyde d'amidoamine, (b) un sel aluminosilicate et (c) un agent alcalin, ladite composition possédant une densité apparente variant entre 0,6 et 1,2 g/ml. Le tensioactif à base d'oxyde d'amidoamine correspond à la formule générale (I) où R1 représente alcényle ou alkyle C10-C20; R2 et R3 représentent chacun H, alcényle ou alkyle C1-C3; R4 représente H, alcényle ou alkyle C1-C5; et enfin, n varie entre 1 et 5.
