ABSTRACT:
This invention relates to use of polyaminoacids as builders or co-builders in the formulation of detergents. These polyaminoacids, which are highly efficient as complexing agents, have good resistance to heat and stability to pH and are entirely biodegradable, have been chosen among those having the general formula: ##STR1## with substituents which are defined in the following description. The formulations of detergents contain, apart from the above builders, surface active agents, alumina-silicates and additives chosen from neutral salts, enzymes, bleaching agents, stabilizers, anti-foaming agents, perfumes, bactericides.
