Abstract

A hair cleansing composition contains (a), (b), and (c). Component (a), as particles having mean particle size of 0.5-50 μm, is a polyalkyleneimine derivative or a salt thereof, having weight average molecular weight of 3,300-50,000, with at least one of R¹—CO—, R²—(CH₂)_n—CHX—CH₂—, and R³—NH—CO— bonded to 40 mol % or more of the N atoms of the polyalkyleneimine. In (a), R¹ represents H, alkyl, alkenyl, or the like; R² represents H, alkyl, alkoxy, alkenyl, or the like; n is 0 or 1; X represents H or OH; R³ represents H, alkyl, or alkenyl; at least one of R¹ to R³ has 13 or more carbon atoms, and the entirety of R¹ to R³ has an average number of carbon atoms of 9 or more and a linear group content of 30 mol % or more. Component (b) is an anionic surfactant. Component (c) is a water-soluble cationic polymer.
