Abstract

A solid textile detergent formulation comprises PA1 (A) from 1 to 30% by weight of inorganic builders based on carbonates, PA1 (B) from 0 to 12% by weight of inorganic builders based on crystalline or amorphous alumosilicates and/or crystalline or amorphous silicates, PA1 (C) from 0 to 5% by weight of inorganic builders based on phosphates, PA1 (D) from 1 to 40% by weight of one or more glycine-N,N-diacetic acid derivatives I ##STR1## PA1 where R is an organic radical and M is hydrogen or a cation, as organic builder component, PA1 (E) from 0 to 40% by weight of anionic surfactants and PA1 (F) from 0.5 to 50% by weight of nonionic surfactants.
