Abstract
Detergent compositions comprising aminodicarboxylic acid-N,N-dialkanoic acid or its salt (component A) and a synthetic surface active agent having microbial degradability (component B). In particular, in the case where an alkali salt of polyoxyalkylene alkylether acetic acid or alkyl polyglycoside is used as the surface active agent (component B), the detergent compositions exhibit excellent washing effect without forming metallic soap even in washing water with high hardness, and also show high solubility even under the condition of low water temperature, and have excellent microbial degradability. Thus, the detergent compositions are particularly suitable for washing fabrics. Further, in the case where synthetic anionic and/or nonionic surface active agent is used as the surface active agent (component B), influence of corrosion to light metals is small. Accordingly, the detergent compositions are suitable for washing light metals, and also they have excellent foaming property and therefore can be applied to foam cleaning.
