PROBLEM TO BE SOLVED: To obtain the subject composition, excellent in rinsing effect and little stimulant to the skin or hair by including a specific quantity of a water-soluble chitosan and a polymer treated to be cationic, and adjusting its pH in a specific range with a basic amino acid. SOLUTION: This composition contains (A) a water-soluble chitosan (e.g. hydroxypropyl chitosan, succinyl chitosan, succinylated carboxymethyl chitosan, chitosan-d1-pyrrolidone-carboxylate) at 0.4 to 2.0 wt.%, and (B) a polymer treated to be cationic e.g. chlorinated O-[2-hydroxy-3-(trimethylammonio) propyl]hydroxyethyl cellulose} at 0.3 to 2.0 wt.%, wherein the total content of the components A and B is 1.0 wt.% or more, the composition being adjusted at pH 7 to 10, preferably 8 to 9, with a basic amino acid (e.g. arginine, lysine or histidine).
