Embodiment

[0163] The following examples illustrate hair coloring or bleaching compositions according to the invention. It should be understood that the examples and embodiments described herein are for the purpose of illustration only and that various modifications or changes thereof will be suggested to persons skilled in the art accordingly without departing from the scope of the present invention. .

[0164] The following hair bleaching compositions were prepared which totally bleached the hair to an equivalent lifting level.

[0165]

[0166]

[0167] Viscosity and hair root adhesion for the control and exemplified compositions were determined using the test method described above and the results are given below. Root adhesion values ​​of 0 and 1 were considered acceptable. Examples 1 and 2 are representative of the prior art and exhibit poor root adhesion.

Abstract

The present invention relates to hair colouring and hair bleaching compositions comprising at least one oxidizing agent, a specified gel network thickener system comprising a specified tertiary system, a cationic polymer and a mica and or titanium oxide. The compositions surprisingly provide improved hair colourant and bleaching compositions which deliver lift, lightening and colour, whilst minimizing damage which are easy to manufacture and which improve adhesion of the composition to the hair roots.

Description

field of invention [0001] This invention relates to hair coloring and hair bleaching compositions. Background of the invention [0002] It is well known to permanently change the color of keratinous fibers, especially human hair, by applying hair dyes. In order to provide the desired hair color and color intensity to the consumer, very complex chemical methods are used. Permanent hair coloring formulations generally comprise oxidative hair dye precursors which can diffuse through the cuticle into the hair and into the cortex, where they can then react with each other, and a suitable oxidizing agent to form the final dye molecule. Due to the larger size of these resulting molecules, they are less likely to diffuse out of the hair during subsequent washes with water and / or detergents, thereby providing the long-lasting color desired by consumers. This reaction typically occurs in an aggressive environment with a pH of about 10 in the presence of alkalizing and oxidizing agen...
