  • Process for stripping keratin fibres using a composition comprising a sulfinic acid derivative and an acidic aqueous composition
    Patent number: 11406578
    Abstract: The present invention relates to a process for stripping keratin fibres, and in particular human keratin fibres such as the hair, dyed with oxidation dyes and/or direct dyes, using a composition obtained by extemporaneous mixing of an anhydrous or aqueous composition (A) comprising at least one suitably selected sulfinic acid derivative and an aqueous composition (B) with a pH of less than (5), comprising at least one organic acid other than the compounds of formula (I), with a pKa of less than or equal to (4) when the composition (A) is aqueous, the pH of the mixture of the two compositions (A) and (B) being less than or equal to (5). The invention also relates to a composition for stripping the artificial colour from keratin fibres, comprising at least one suitably selected sulfinic acid derivative and at least one thickener chosen from anionic polymers and nonionic polymers.
    Type: Grant
