Abstract: Ready-to-use oxidizing composition comprises: at least one oxidizing agent; at least 30 wt.% of at least one water-insoluble non-dyeing oxygenated organic compound, having a solubility of less than 0.5 wt.% in water at ambient temperature (25[deg] C), where the water insoluble non-dyeing oxygenated organic compound is polymeric in nature and comprises polyamide 6, 66 or 11, polyester, polyurethane, polycyanoacrylate, methyl polymethacrylate, polycarbonate, Teflon(RTM: Polytetrafluoroethylene), resin or silicone elastomers; and at least 30 wt.% of water, in a medium. Independent claims are included for: (1) a process for bleaching human keratin fibers, preferably hair, comprising applying the ready-to-use oxidizing composition on the area of human keratin fibers for bleaching, leaving the composition for an exposure time sufficient for acting to obtain the desired bleaching, eliminating the composition by a water rinse, followed by washing with a shampoo, and then optionally drying; (2) a process for stripping of human keratin fibers, preferably colored hair, comprising applying the ready-to-use oxidizing composition on the area of colored human keratin fibers to be stripped, leaving the composition for an exposure time sufficient for acting to obtain the desired stripping, eliminating the composition by water rinse, followed by washing with shampoo, and then optionally a drying; (3) a process for oxidation dyeing of human keratin fibers and preferably hair, comprising applying an dyeing composition comprising at least one precursor of oxidation dye and the ready-to-use oxidizing composition in the medium, on the fibers, for dyeing keratin fibers, where the oxidizing composition is applied before or after applying the dye composition or mixed with the coloring composition, leaving the individual compositions or mixtures for 1-60 minutes, preferably 5-40 minutes, rinsing, washing with shampoo and optionally followed by rinsing and drying; (4) a direct coloring process for lightening keratin fibers, preferably human hair, comprising applying the dye composition comprising at least one direct dye and the oxidizing composition ready for use on medium for dyeing keratin fibers, on the fibers, applying the oxidizing composition on the keratin fibers before or after the application of the dye composition or mixed with the coloring composition, leaving the individual composition or mixed compositions for 1-60 minutes, preferably 5-40 minutes, rinsing and washing with shampoo, and optionally again rinsing and then drying; (5) a process for permanent deformation of keratin fiber, preferably human hair, comprising applying a reducing composition on the keratin fiber to be treated, where the keratin fiber is put in mechanical tension before, during or after the application, letting the hair for rest on which the reducing composition is applied, optionally rinsing with an aqueous composition, applying the oxidizing composition on the keratin fibers, and rinsing with an aqueous composition; and (6) a device having two compartments for coloring, for permanent deformation, for bleaching of keratin, preferably human keratin fibers, comprising a first compartment either containing the oxidation dyeing composition or direct dyeing composition, reducing composition, a first oxidizing composition, preferably peroxygenated salt, and a second compartment containing the oxidizing composition.
