Abstract

The present invention provides a detergent composition containing N-acyl acidic amino acids that, even at low pH, exhibits excellent solubility, has good storage stability, and creates a quality foam with satisfactory lathering performance. Specifically, the present invention provides a detergent composition and the like comprising:

(A) an N-unsaturated acyl acidic amino acid wherein the unsaturated acyl is a linear acyl with 8 to 20 carbon atoms;(B) an N-saturated acyl acidic amino acid wherein the saturated acyl is a linear acyl with 8 to 14 carbon atoms; and(C) optionally, an N-saturated acyl acidic amino acid wherein the saturated acyl is a linear acyl with 16 to 20 carbon atoms;wherein the weight ratio of the component (A) to the component (B) (A/B) is 0.01 to 0.80, andthe weight ratio of the component (C) to the component (B) (C/B) is 0.00 to 0.32.
