Problems solved by technology

[0007] In fact, another shortfall in current hair coloring products is the availability of hair coloring products that deliver desired hair lightening benefits
[0011] However, it has now been found that a problem associated with the use of hydrogen peroxide and carbonate hair colorant systems is that hair colorant compositions can, under certain conditions, lead to significant damage to the hair fiber, at high levels of peroxide and carbon This is especially true in the presence of acid salts
As a result, the hair fiber is sufficiently weakened and becomes so brittle that it breaks during the consumer's hair care routine

Abstract

The present invention relates to hair colouring and bleaching compositions comprising i) at least one source of peroxymonocarbonate ions, ii) at least one alkalizing agent, preferably a source of ammonium ions, and iii) at least one radical scavenger, wherein said composition has a pH of up to 9.5, which provide a high level of lift and lightening and the required dye deposition and grey coverage whilst reducing the concentration of peroxide, the ammonia odour and reducing the hair fibre damage.

Description

field of invention [0001] The present invention relates to compositions for bleaching and dyeing keratinous fibres. Background of the invention [0002] It is well known to permanently alter the color of keratinous fibers, especially human hair, by the use of hair dyes. In order to deliver the hair color and desired shade to the consumer, very complex chemical methods are used. Permanent hair coloring formulations typically include oxidative hair dye precursors which diffuse through the cuticle into the hair and into the cortex where they then react with each other and with a suitable oxidizing agent to form the final dye molecule. Due to the larger size of these resulting molecules, they cannot easily diffuse out of the hair during subsequent washes with water and / or detergent; thereby delivering the color permanence desired by the consumer. This reaction typically takes place in an aggressive environment with a pH of about 10 in the presence of alkalizing and oxidizing a...
