Use of glycine-N,N-diacetic acid derivatives as biodegradable complexing agents for alkaline earth metal ions and heavy metal ions and process for the preparation thereof

摘要

Glycine-N,N-diacetic acid derivatives and their alkali metal, alkaline earth metal, ammonium and substituted ammonium salts are used as complexing agents for alkaline earth metal and heavy metal ions with the exception of -alanine-N,N-diacetic acid as textile detergent builders in powder detergent formulations and as calcium sequestrants in oral hygiene products.
