CA 2437170

The present invention relates to hair care compositions comprising an oxidizing agent and chelants having a log KCuL/log KCaL ratio calculated at pH 10 of at least 3.20 wherein log KCuL is the common logarithm of the Conditional Stability Constant of said chelant with Cu2+ and log KCaL is the common logarithm of the Conditional Stability Constant of said chelant with Ca2+. Suitable chelants are diamine-N,N'-dipolyacids or monoamine monoamide- N,N'-dipolyacids. The compositions according to the present invention contribute to reducing the oxidative damage sustained by a keratinous fiber such as hair during bleaching, dyeing, perming or other oxidative treatments. Especially preferred diamine dipolyacid is ethylenediamine-N,N'-disuccinic acid (EDDS).

La présente invention concerne des compositions capillaires comprenant un oxydant et des chélatants présentant un rapport log K¿CuL?/log K¿CaL? calculé d'au moins 3,20 pour un pH de 10. En l'occurrence, log K¿CuL? est le logarithme commun de la constante de stabilité conditionnelle dudit chélatant avec Cu?2+¿, log K¿CaL? étant le logarithme commun de la constante de stabilité conditionnelle dudit chélatant avec Ca?2+¿. Les chélatants appropriés sont les diamine-N,N'-dipolyacides ou les monoamide-N,N'-dipolyacides de monoamine. Les compositions selon la présente invention contribuent à réduire la détérioration par oxydation subie par une fibre kératineuse et notamment les cheveux pendant un traitement oxydant tel que la décoloration, la teinture ou le permanentage. Le dipolyacide de diamine particulièrement préféré est l'acide éthylènediamine-N,N'-disuccinique (EDDS).
