Description

A MULTI-COMPARTMENT DEVICE AND METHODS THEREOFFIELD OF INVENTION

[0001] The present disclosure relates to the field of hair dyeing products, particularly to devices and compositions for treating keratin fibres. The present disclosure further relates to methods of dyeing of keratin fibres, in particular hair.BACKGROUND OF INVENTION

[0002] Use of hair dyeing products is increasing day by day and many people are keen nowadays to modify their hair colour and in particular to mask their grey hairs.

[0003] It is a known practice to dye keratin fibres, such as the human hair to obtain “permanent” colourings with dyeing compositions containing oxidation dye precursors, notably oxidation bases, such as ortho- or para-phenylenediamines, ortho- or para-aminophenols, or heterocyclic compounds such as pyrazoles, pyrazolinones or pyrazolo-pyridines. These oxidation bases are colourless or weakly coloured compounds which, when combined with oxidizing products, may give rise to coloured compounds via a process of oxidative condensation.

[0004] Further, various shades of colours could be obtained with these oxidation bases by combining them with couplers or colour modifiers. The variety of molecules used as oxidation bases and couplers allows a wide range of colours to be obtained.

[0005] Nevertheless, the use of these dyeing compositions may have a certain number of drawbacks. In particular, post-application, the results achieved in terms of cosmetic properties may not be entirely satisfactory. The dyeing effect obtained may be weak or may lead to use of restricted range of colours. The colourings may also be insufficiently persistent with respect to external agents such as light, shampoo or perspiration, and may also be too selective, i.e. the difference in colouring is too great along the same keratin fibre that is differently sensitized between its end and its root.

[0006] Additionally, consumers are in search of dyeing products which have good working qualities, easy to use and give good dyeing properties.

[0007] Therefore, there is a need for composition for dyeing keratin fibres such as human hair, which does not have the abovementioned drawbacks and those which are capable of giving good colour build-up, having good working qualities such as ease of mixing, ease of application and ease of rinsing yet leading to good cosmetic properties.SUMMARY OF THE INVENTION

[0013] The product or device for dyeing human keratin fibres, such as the hair, according to the invention may notably lead to chromatic, powerful, intense and sparingly selective colourings, i.e. colourings that are uniform along the length of the fibre. It also allows various shades to be achieved in a very wide range of colours, notably lighter shades.
