Definitions

• the invention relates to aqueous preparations of hydrogen peroxide, which are particularly suitable as oxidizing agent preparations for bleaching and for oxidative coloring of the hair with oxidizing coloring agents.
• the bleaching and dyeing of the hair with oxidation hair dyeing agents is generally carried out with the aid of two separately packaged preparations - the bleaching cream or oxidation hair dyeing cream (A) and the oxidizing agent preparation (B) - which are combined only shortly before use and in one Application bottle is mixed by simple shaking and then applied to the hair as a ready-to-use blending or dyeing preparation.
• Two-chamber mixing and dispensing containers have also been developed for home use, in which components A and B are packed separately from one another in a suitable quantity ratio and have a partition which can be mechanically destroyed from the outside between the two chambers and a dispensing opening on one of the two chambers . Shortly before use, the partition is destroyed, whereupon components A and B are combined and mixed by shaking or other mechanical measures. Then the ready-to-use hair dyeing or bleaching preparation can be removed through the dispensing opening or applied directly to the hair to be colored.
• a rapid and homogeneous mixing of the bleaching or coloring cream (A) and the oxidizing agent preparation (B) is very important for the success of the dyeing process.
• Foaming is caused primarily by the fact that the oxidizing agent preparations, generally aqueous preparations of hydrogen peroxide, contain strongly foaming anionic surfactants for stabilization. These are necessary in order to stabilize the dispersions of alkali-soluble, thickening, carboxyl-containing polymers contained in such preparations for increasing viscosity after mixing. Bleaching and oxidation dye creams also often contain highly foaming anionic surfactants in order to keep the fatty alcohols dispersed in these products for viscosity build-up in the dispersed state. Since the use of these high-foaming anionic surfactants cannot be avoided for the reasons mentioned, the problem arises of controlling the development of foam by means of a suitable additive.
• the invention relates to aqueous preparations of hydrogen peroxide for the oxidative dyeing and bleaching of the hair with a content of anionic surfactants and a thickening, carboxyl group-containing polymer or copolymer with addition of a nonionic surfactant of the formula I which is soluble in aqueous alkali

• the nonionic surfactants of the formula I to be used according to the invention for foam control are substances which are known per se and are commercially available. They are produced by adding x moles of ethylene oxide to fatty alcohols, preferably to linear, saturated fatty alcohols, with 10-22 carbon atoms and then adding a less hydrophilic end group R 2 . This end group can be introduced, for example, by adding 3-5 moles of propylene oxide to the ethoxylate.

After unscrewing the the contents were mixed by hand shaking. It was found that the preparation 1, 3 not according to the invention was only mixed with the cream so homogeneously after very long shaking that no inhomogeneities could be seen with the naked eye. The reason for the poorer mixing was obviously due to the strong foaming, which hindered the mechanical movement of the liquid when shaken.
• the ready-to-use dyeing preparations obtained after mixing were applied to the hair in a customary manner and washed out with water after the exposure time. When washing out, a sufficient amount of foam still developed in the preparations according to the invention.
