Abstract: The present disclosure concerns colouring agents for keratinous fibres, in particular for human hair, which—with respect to its weight—contain at least one compound selected from the group formed by oxidative dye precursors, direct dyes and mixtures thereof, from about 0.1 to about 5% by weight of dicarboxylic acid(s) containing from about 2 to about 10 carbon atoms and/or salt(s) of this(these) acid(s), from about 20 to about 95% by weight of water, and less than about 0.1% by weight of peroxy compound(s), to produce oxidative colouring agents with improved protection of fibres.

Abstract: A first subject of the present disclosure is a special oxidant preparation for oxidative coloring of keratinous fibers, more particularly human hair, included in a cosmetic carrier (A) hydrogen peroxide and (B) at least one acid from the group of sulfuric acid, hydrochloric acid, phosphoric acid, lactic acid, citric acid, malic acid, tartaric acid, maleic acid, succinic acid, oxalic acid, ascorbic acid, phytic acid, gluconic acid, nitric acid, malonic acid, acetic acid and-or C3-C22 alkane carboxylic acids, wherein the oxidant preparation has a pH value of from about 0.5 to about 3.0. Additional subjects of the present disclosure are methods for oxidative color changing of human hair in which this special oxidant preparation is used.

Abstract: The aim of the present disclosure was to provide an improved oxidizing agent preparation for oxidative color modifying agents, which are present as soap based gels and contain ammonia as the alkalizing agent and optionally at least one oxidation dye precursor, and have a pH in the range of from 8 to 11.5, measured at 20° C., with which homogeneous and viscosity-stable application mixtures can be produced that release less ammonia during the entire leave-in time. It was surprisingly found that aqueous hydrogen peroxide preparations which contain selected 1-alkanols, glyceryl fatty acid esters, ethoxylated fatty alcohols, polyols and oils, achieve said aim in a very satisfactory manner.
