摘要：
Detergency builder/cobuilder preformulations, for improvedly stable/biodegradable detergent compositions, comprise intimate admixture of at least one polyimide polymer and at least one silicate, advantageously in the form of cogranulates thereof, said at least one polyimide polymer generating at least one biodegradable water-soluble polypeptide species when contacted with an aqueous medium having a non-alkaline pH.
