Abstract

Abstract A detergent composition containing at least one ampholytic surface active agent of N.sup.ε -long-chain-acyl-N.sup.ε,N.sup.ε -dimethyllysine or N.sup.ε -long-chain-acyl-N.sup.α,N.sup.α,N.sup.α -trimethyllysine or salt thereof represented by formula (I) or (II) below, and an anionic surface active agent. This detergent composition is superior in solubility, detergency, and sudsing on account of the synergistic effect of the two types of different components. This detergent composition exhibits high detergency in both soft water and hard water, and is mild to the skin and hair. ##STR1## (where RCO denotes an aliphatic acyl group of carbon number 8 to 22.).
