Abstract:
1. A composition suitable for treating hair comprising: a) an oxidizing agent; and b) a chelant (L) having a ratio calculated at pH 10 of at least about 3.20, wherein log K CuL is the common logarithm of the Conditional Stability Constant of said chelant with Cu 2+ and log K CaL is the common logarithm of the Conditional Stability Constant of said chelant with Ca 2+ ; wherein said chelant is an aminocarboxylic acid chelant selected from the group consisting of ethylenediamine-N,N′-disuccinic acid (EDDS), ethylenediamine-N,N′diglutaric acid (EDDG), 2-hydroxypropylenediamine-N,N′-disuccinic acid (HPDDS), glycinamide-N,N′-disuccinic acid (GADS), ethylenediamine-N-N′-bis(ortho-hydroxyphenyl acetic acid) (EDDHA), and salts thereof, derivatives thereof and mixtures thereof; and wherein said chelant is in an amount sufficient to provide a Normalized Shine Ratio of at least about 0.95 as measured by the Goniophotometer Damage Assessing Protocol after a 5-Cycle Hair Oxidative Treatment Protocol With 10 Intermediate Washes.
