    • PROBLEM TO BE SOLVED: To obtain a detergent composition which not only is free from the occurrence of deposition of a precipitate or separation with the passage of time, but also can produce a good feel of smoothness and has a viscosity suitable for comfortable use and is extremely excellent in stability of viscosity, and which is, in particular, suitably used as a washing agent for hair such as a shampoo, by incorporating an N-acylglutamic acid salt, a xanthane gum and a quaternary nitrogen-containing cellulose ether into the composition. SOLUTION: As an N-acylglutamic acid slat, use is made of the one having a mixed acyl group derived from a mixed fatty acid such as palm oil fatty acid, hydrogenated beef tallow fatty acid or the like as well as the one having a single acyl group derived from a single fatty acid of an 8-22C acid residue. A quaternary nitrogen-containing cellulose ether is a catiuonated cellulose ether represented by the formula. It is preferred that an N-acylglutamic acid salt, a xanthane gum and a quaternary nitrogen-containing cellulose ether are compounded in amounts of 5 to 50 wt.%, 0.01 to 3 wt.% and 0.01 to 3 wt.% based on the total amount of the composition, respectively.
