Abstract

Cette invention concerne une composition détergente granulaire d'une densité élevée, laquelle possède d'excellentes qualités détergentes contre les salissures grasses. Cette composition comprend (a) de 3 à 50 % en poids d'un tensioactif alkylolamide correspondant à la formule générale (1) où R1 représente un alcényle ou alkyle C8-C20, R2 représente H ou un alcényle ou alkyle C1-C3, et n varie entre 2 et 6. Cette composition, qui comprend également (b) de 5 à 60 % en poids d'un aluminosilicate et (c) de 5 à 60 % en poids d'un agent alcalin, possède une densité apparente de 0,5 à 1,2 g/ml.
