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 .alpha.-alanine-N,N-diacetic acid as textile detergent builders in powder detergent formulations and as calcium sequestrants in oral hygiene products.
