Disclosed is the use of certain alkanolamines for use in hair treatment compositions as a replacement for some or all ammonium hydroxide. When used as hair colorant alkalizers, these derivatives demonstrate reduced hair fiber damage, effective color lifting, and significant improvement in cytotoxicity and malodor compared to well known replacements for ammonium hydroxide.

The present disclosure relates to cosmetic compositions for the oxidative treatment of keratinous fibers, in particular human hair, comprising at least one salt of a peroxo compound, at least one alkalizing agent and at least one complexing agent. Furthermore, it is an object of the present disclosure to provide a multi-component unit for the oxidative lightening of keratinous fibers, in particular human hair, comprising as first component the cosmetic agent as contemplated herein and as second component an agent comprising H.sub.2O.sub.2. In addition, the present disclosure relates to the use of a salt of a polyhydroxylated monocarboxylic acid in a cosmetic composition.

The present invention relates to a composition for keratin fibers comprising: (a) at least one non-neutralized anionic surfactant; (b) at least one non-ionic surfactant; (c) at least one fatty alcohol; and (d) at least one alkaline agent, wherein the composition does not comprise more than 2% by weight of a phosphoric surfactant. The present invention can provide the composition for keratin fibers which can suppress its ammonium odor and have improved stability.
