Pretreatment composition (PC) comprising malic acid and DTPMP for a colouring or bleaching process of keratin fibers

Abstract

The presently claimed invention relates to a composition (PC) comprising as components malic acid and/or malic acid salt(s) (component (A)), at least one chelant comprising diethylenetriamine penta(methylene phosphonic acid) and/or diethylenetriamine penta(methylene phosphonic acid) salt(s) (component (B)), at least one thickener (component (C)), at least one cosmetically acceptable solvent (component (D)), at least one surfactant (component (E)) and, optionally, at least one care ingredient (component (F)). Another aspect of the presently claimed invention relates to the use of the composition (PC) as a pretreatment composition for a colouring or bleaching process, the use of a composition (PC) for protecting keratin fibers during a colouring or bleaching process and a process for coloring or bleaching keratin fibers, wherein the composition (PC) is applied to keratin fibers. Another aspect of the presently claimed invention relates to a kit comprising the composition (PC) and an oxidative hair colouring composition (HC). Another aspect of the presently claimed invention relates to a multidepartment device comprising a first compartment containing the composition (PC) and a second compartment containing an oxidizing composition.
