  • Use of dihydroisoquinolinium salts for treating keratin materials, compositions and implementation processes
    Patent number: 11406580
    Abstract: Use of dihydroisoquinolinium salts for treating keratin materials, compositions and implementation processes The present invention relates to the use of one or more dihydroisoquinolinium 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 salts as defined below and one or more chemical oxidizing agents.
    Type: Grant
