    • One subject of the invention is a composition comprising: (a) at least one cationic surfactant of formula (I) or (I´) below: where: R 1, represent a hydrogen, a C 1 -C 6 alkyl, optionally bearing at least one hydroxyl or alkoxy; R 2 , which may be identical or different, represent a C 1 -C 6 alkyl; R 3 representing a C 8 -C 32 hydrocarbon-based radical, optionally bearing at least one hydroxyl; -CH 2 0-R' 3 with R' 3 representing a C 8 -C 32 hydrocarbon-based radical, optionally bearing at least one hydroxyl; n is equal to 2 or 3; p is equal to 0 or 1 and the sum of n and p is equal to 3; R' 1 , represents a C 1- C 6 alkyl, optionally bearing at least one hydroxyl or alkoxy; R' 2 represents a C 1- C 6 alkyl, optionally bearing at least one hydroxyl or alkoxy; a radical -CH 2 -CH(OH)-[CH(OH)] n '-H with n' representing an integer ranging from 1 to 4; R' 3 representing a C 8 -C 32 hydrocarbon-based radical, optionally bearing at least one hydroxyl; a radical -CH(OH)-(CH20)P-R" 3 with R" 3 representing C 8 -C 32 hydrocarbon- based radical, optionally bearing at least one hydroxyl, p being equal to 0 or 1; m is an integer ranging from 1 to 3; X" represents a counterion; and (b) at least one oxidizing agent; (c) at least one dye or at least one alkaline agent, or mixtures thereof. Other subjects of the invention include a method for treating keratin fibres, in which this composition is applied, and also a multicompartment device comprising, in a first compartment, a composition that is free of oxidizing agent and, in another compartment, a composition comprising this oxidizing agent, the cationic surfactant(s) of formula (I) or (I´) being, without preference, in one and/or the other of the compartments. The invention finally relates to the use of these cationic surfactants of formula (I) or (I´) for dyeing or bleaching human keratin fibres, especially the hair.
