Present invention relates to an aqueous oxidizing composition with improved peroxide stability. The aqueous compositions of the present invention comprises at least oxidizing agent, at least one magnesium salt and have a pH between 1 and 5.

Aqueous oxidizing composition

The present invention relates to bleaching composition for keratin fibers, especially human hair, comprising at least one compound with bleaching and/or highlighting effect and a calcium salt. Further object of the present invention is the use of at least one calcium salt in a bleaching and/or highlighting composition for keratin fibers, especially for human hair, comprising at least one compound with bleaching and/or highlighting effect for preventing temperature increase going above 40&#xb0; C., preferably above 45&#xb0; C. and more preferably above 50&#xb0; C. in a period of at least 60 min after mixing water free bleaching and/or highlighting composition and oxidizing lotion.

Bleaching/highlighting composition containing calcium salts

The present invention relates to bleaching composition for keratin fibers, especially human hair, comprising at least one compound with bleaching and/or highlighting effect and a quaternized hydroxyethyl cellulose polymer with cationic substitution of trimethyl ammonium and dimethyldoceyl ammonium.

Bleaching composition

The present invention relates to bleaching composition for keratin fibers, especially human hair, comprising at least one compound with bleaching and/or highlighting effect and a magnesium salt. Further object of the present invention is the use of at least one magnesium salt in a bleaching and/or highlighting composition for keratin fibers, especially for human hair, comprising at least one compound with bleaching and/or highlighting effect for preventing temperature increase going above 50&#xb0; C., preferably above 45&#xb0; C. and more preferably above 40&#xb0; C. in a period of at least 60 min after mixing water free bleaching and/or highlighting composition and oxidizing lotion.

Bleaching composition comprising magnesium salt

The present invention is related to an oxidative colouring composition for keratin fibres especially human hair. The present invention is a composition comprising at least one hair dye and at least one magnesium salt. Furthermore, it is the use of at least one magnesium salt in a composition comprising at least one hair dye for preventing warming up and increase of its volume upon mixing with an aqueous composition comprising at least one oxidizing agent. Present invention is at the same time on the process for colouring keratin fibres with the use of the compositions.

Oxidative colouring composition

The present invention relates to a process for oxidative coloring keratin fibers especially human hair wherein dyeing composition comprises a cross linked copolymer. The objective of the present invention is a process for oxidative coloring hair wherein compositions A and B are mixed, composition A comprises at least one oxidative dye precursor and optionally at least one coupling agent and optionally at least one direct dye in a cosmetically acceptable medium and composition B comprises at least one oxidizing agent in a cosmetically acceptable medium, and applied onto hair and processed for 1 to 45 min at a temperature range of 20 to 45&#xb0; C. and rinsed off from hair, wherein at least one of the two compositions A and B comprises a cross linked copolymer of vinylpyrrolidone, vinylimidazol, 3-methyl-1-vinylimidazolium and methacrylic acid.

Composition and process for oxidative colouring keratin fibers

The present invention relates to bleaching composition for hair comprising at least one compound with bleaching and/or highlighting effect and at least one dipeptide.
