Definitions

  • This invention relates to hair coloring compositions and processes for coloring hair, and more especially to hair coloring compositions comprising a source of hydrogen peroxide and a bleaching aid selected from organic peroxyacid bleach precursors and/or preformed organic peroxyacids in combination with one or more hair coloring agents.
  • the primary colored component of human or animal hair is melanin pigment. Melanin occurs naturally within the hair cortex in 'granular' form. To successfully color human or animal hair it is generally necessary to decolorize the hair prior to the application of the coloring agent(s) of choice. This decolorization process is generally referred to as hair bleaching.
  • the objective of hair bleaching compositions is to selectively decolorize both the naturally occurring melanin pigment in hair and in addition any synthetic pigments previously applied to the hair with minimal damage to the hair structure. When hair is bleached, the color changes to lighter and lighter shades depending upon the amount of melanin oxidised and removed from the hair in the decoloring process.
  • Bleaching compositions used on hair differ from those used with textiles, fabrics, hard surface cleansing and the like, such as sodium hypochlorite, in that hair bleaching compositions, in addition to oxidising and destroying the colored melanin of the hair, must be suitable for use in contact with the human skin and must not damage the hair excessively. Furthermore, since hair bleaches are a member of the class of materials known as cosmetics, it is desirable that they be aesthetically acceptable to the user. Finally, it is desirable that a hair bleaching composition remove the melanin coloration from the hair as quickly as possible for the sake of convenience and to help prevent untoward damage to the hair and irritation to the skin and scalp.
  • Hydrogen peroxide is the most commonly used hair bleaching / melanin oxidising agent.
  • hydrogen peroxide treatment of the hair not only solubilises the melanin but can also lead to undesirable hair qualities, such as increased brittleness, and to hair damage, which are in part due to the preferred conditions of conventional peroxide treatment which requires high pH (> pH 9), extended exposure (from 20 to 90 minutes) and relatively high concentration of bleaching solutions (up to 30% volume of oxygen) in order to deliver effective bleaching.
  • Hair bleaching and coloring compositions commonly contain a source of peroxide, bleach activating agents and a variety of additional cosmetic and bleach stabilising agents.
  • Peroxide bleaches must be 'activated' to effect hair bleaching, this typically being accomplished by the use of an 'activating agent' to adjust the pH of the bleaching solution accordingly.
  • the activating material for adjusting the pH of peroxide hair bleaching compositions is an aqueous (alkaline) solution containing ammonia (ammonium hydroxide).
  • ammonia ammonium hydroxide
  • certain 'activator 1 materials may also act as hair swelling agents (HSA's).
  • HSA's hair swelling agents
  • Such HSA's further enhance the bleaching and coloring process by swelling the hair fibres to aid both the diffusion of the peroxide and coloring agents into the hair and enabling faster, more thorough bleaching (solubilisation /decolorisation of the hair melanin) and subsequent coloring.
  • Ammonia is a particularly effective HSA. However ammonia can cause skin irritation when used at levels of about 1% by weight of composition or higher.
  • Persulphate type bleaches have been proposed in the hair care area as alternative bleaching systems. However persulphate is a less effective bleach versus conventional peroxide bleaches, requiring higher concentration and longer exposure to effect an equivalent degree of bleaching to conventional bleach.
  • hair coloring compositions comprising the combination of conventional peroxide oxidising agents with certain bleaching aids and one or more coloring agents can deliver excellent hair coloring over time in combination with reduced hair damage at a lower pH and in a faster time. Furthermore, applicant has found that the combination of certain bleaching aids with a source of peroxide at particular levels and ratios in the coloring compositions of the present invention can deliver excellent hair coloring results, minimal hair damage, are effective at lower pH and can work in a faster time.
  • the subject of the present invention is a hair coloring composition suitable for the treatment of human or animal hair, comprising:

Moreover, it is also intended to include complex compositions which contain other components which may or may not be active ingredients. Thus, the term 'hair coloring composition' is intended to apply to compositions which contain, in addition to a mixture of active oxidising or bleaching agents and coloring agents such things as, by way of example, sequestrants, thickeners, buffers, carriers, surfactants, surface active agents, solvents, alkalising agents, antioxidants, polymers and conditioners.

This decolorization process is generally referred to as hair bleaching. As herein before described such bleaching is commonly effected via the use of oxidising agents. It is further understood by those familiar in the art that hair bleaching via use of oxidising agents is a two-step process. Firstly the colored melanin pigment in the hair is solubilised and secondly the solubilised melanin pigment is decolored.

  • Temporary hair dyes, or hair coloring rinses are generally comprised of dye molecules which are too large to diffuse into the hair shaft and which act on the exterior of the hair. They are usually applied via a leave-in procedure in which the dye solution is allowed to dry on the hair surface. As such these dyes are typically less resistant to the effects of washing and cleaning the hair with surface active agents and are washed off of the hair with relative ease. Any temporary hair dye may suitably be used in the compositions of the invention and examples of preferred temporary hair dyes are illustrated below.
  • Semi-permanent hair dyes are dyes which are generally smaller in size and effect to temporary hair rinses but are generally larger than permanent (oxidative) dyes.
  • semi-permanent dyes act in a similar manner to oxidative dyes in that they have the potential to diffuse into the hair shaft.
  • semi-permanent dyes are generally smaller in size than the aforementioned conjugated oxidative dye molecules and as such are pre ⁇ disposed to gradual diffusion out of the hair again.

  • Typical semi-permanent dye systems incorporate mixtures of both large and small color molecules. As the size of the hair is not uniform from root to tip the small molecules will diffuse both at the root and tip, but will not be retained within the tip, while the larger molecules will be generally only be able to diffuse into the ends of the hair. This combination of dye molecule size is used to help give consistent color results from the root to the tip of the hair both during the initial dyeing process and during subsequent washing.
