Abstract: The present invention relates to a two part aqueous oxidative colouring composition for keratin fibres especially human hair with improved and homogeneous conditioning effect from root to tip, improved colour fastness against washing and for achieving homogeneous even colouration. Present invention is on a two part aqueous composition for colouring keratin fibres especially human hair, characterised in that the first part A is an aqueous composition and comprises at least one oxidative dye precursor, optionally at least one coupling agent and/or at least one direct dye and furthermore comprising at least one anionic surfactant the second part Part B is an aqueous composition and comprises at least one oxidizing agent and at least one cationic polymer.

Abstract: The present invention relates to an aqueous oxidative colouring composition for keratin fibres especially human hair with improved conditioning effect, improved colour fastness against washing and for achieving homogeneous even colouration. The object of the present invention is an aqueous composition for colouring keratin fibres especially human hair, based on at least one oxidative dye precursor, optionally at least one coupling agent and/at least one direct dye and furthermore comprising in a cosmetically acceptable medium at least one anionic surfactant, at least one branched fatty acid and at least one quaternary ammonium surfactant.

Abstract: Present invention relates to a colouring composition for keratin fibres especially for human hair with exceptionally improved colour and shade stability. Accordingly, the first object of the present invention is a colouring composition for keratin fibres especially human hair comprising, in a cosmetically acceptable medium, at least one oxidative dyestuff precursor, 1,3-bis(2,4-diaminophenoxy) propane and/or its respective salts as a coupling agent and at least one direct dye. In an especially preferred from of the present invention the colouring compositions are substantially free from mono cyclic m-phenylenediamine coupling agent. With the term “mono cyclic m-phenylenediamine”, it is meant that the compound comprises only one cyclic group, preferably a benzene ring, in its molecule.

Abstract: There is provided a head hair dyeing method using a two-part hair dye composition which contains: a first part containing a first part stock solution and a propellant, the first part stock solution containing an alkali agent and a surfactant; a second part containing a second part stock solution and a propellant, the second part stock solution containing hydrogen peroxide and a surfactant; and two aerosol containers for respectively discharging the first part and the second part as foam, the method including respectively discharging the first part and the second part as foam from the containers, applying the foam mixture to the head hair, and then re-foaming the mixture on the head hair.

Abstract: The present invention relates to the use of alkanolamines for thickening oxidative coloring compositions. More particularly, the present invention relates to the use of alkanolamines for thickening ready to use oxidative coloring composition based on mixing two compositions wherein one comprises at least one oxidative dyeing precursor and the other comprises as least one oxidizing agent.

Abstract: The present invention relates to a hair cuticle caring method or volume enhancing method, which comprises treating hair with a composition containing (A) a cationic surfactant and (B) an organic acid or salt thereof in a combination to give, when an aqueous solution containing 1 mM of each of the components is formed, 40 mN/m or less as the surface tension of the aqueous solution at 27±0.5° C. By the application of the above-described composition, the lift-up of the hair cuticle can be suppressed, the volume can be enhanced softly, moisturized but stickiness-free feeling is imparted and styling ease is improved.
