    Abstract: The present invention relates to the use of one or more dihydroisoquinolinium double salts for treating keratin materials, in particular keratin fibres, especially human keratin fibres such as the hair. The invention also relates to a process for treating keratin materials using said salts and optionally in the presence of one or more chemical oxidizing agents. A subject of the invention is also a composition for lightening keratin materials, comprising one or more dihydroisoquinolinium double salts as defined below and one or more chemical oxidizing agents. The present invention also relates to one or more particular dihydroisoquinolinium double salts and also to compositions containing them, in particular compositions comprising a physiologically acceptable medium.

    Abstract: The invention relates to primary para-phenylenediamine compounds substituted with an aliphatic chain comprising a cationic heterocyclic group according to formula (I), as well as the organic or mineral acid or base addition salts thereof, optical isomers, geometric isomers, tautomers, mesomers and/or solvates thereof, such as hydrates. Formula (I), wherein: ALK is a linear or branched, optionally substituted, alkylene chain comprising 3 to 8 carbon atoms; HET+ is a saturated or unsaturated, aromatic or non-aromatic cationic heterocyclic group, optionally substituted, comprising 5 to 0 links, optionally substituted, and comprising one or more ammonium groups; and An−, present or absent, is a mineral or organic anionic counterion ensuring the electroneutrality of the molecule. The present invention also relates to a composition comprising one or more of these previously defined compounds, in a medium suitable for dyeing. The present invention lastly relates to a dyeing device consisting of a first compartment which contains said composition, and a second compartment containing one or more oxidising agents.
