Abstract

A solid textile detergent formulation, comprising (A) 1-60% by weight of inorganic builders based on crystalline or amorphous aluminosilicates, crystalline or amorphous silicates, carbonates and/or phosphates, PA0 (B) 0.1-25% by weight of one or more glycine-N,N'-diacetic acid derivatives I ##STR1## where R is an organic radical and M is hydrogen or a cation, as organic cobuilders, PA0 (C) 1-40% by weight of anionic surfactants and PA0 (D) 0.5-30% by weight of nonionic surfactants.
