    摘要： 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.

    摘要： The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, in one or more steps, comprising the application to said keratin fibres of a composition comprising one or more compounds of formula (I) and/or (II), and also to the use thereof for dyeing keratin fibres, and to a device: in which formula (I) or (II) R1, R3, R4, R5, R6, and n are as defined in the description. The compounds of formula (I) according to the invention can give powerful, chromatic and sparingly selective colourings with good colour build-up, which are resistant to the various attacking factors to which keratin fibres may be subjected, such as inclement weather, light, washing and perspiration.

    摘要： The present invention relates to the use of one or more particular dihydroisoquinolinium salts of formula (I) 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 one or more chemical oxidizing agents. A subject of the invention is also a composition for lightening keratin materials, comprising one or more dihydroisoquinolinium salts and one or more chemical oxidizing agents.
