Definitions
- the present invention relates to enzymatic foam compositions for bleaching or dyeing keratinous fibres such as hair, fur, hide and wool, a method for dyeing such fibres, and the use of a composition containing an oxidation enzyme and a foaming agent for dyeing hair and other keratinous fibres.
- Hair is often dyed to cover grey hair that appears with age. Further, during the last few decades, hair dyeing has become more and more popular in the western world for purely cosmetic purposes, i.e. the hair is dyed a different colour than its natural colour in order to obtain a desired "look" .
- hair dyeing compositions on the market today can be divided into three main groups:
- the temporary hair dyes are only intended to change the natural hair colour for a short period of time and usually function by depositing dyes on the surface of the hair. Such hair dyes are easy to remove with normal shampooing.
- the dyed colour can survive for five or more shampooings. This is achieved by using dyes having a high affinity for hair keratin and which are able to penetrate into the interior of the hair shaft. Permanent hair dyes are very resistant to sunlight, shampooing and other hair treatments and need only be refreshed about once a month as new hair grows out. With these dyeing systems, the dyes are created directly in and on the hair. Small aromatic dye precursors (e.g. p-phenylene-diamine and o-aminophenol) penetrate deep into the hair, where they are oxidised by an oxidising agent to coloured polymeric compounds. These coloured compounds are larger than the dye precursors and cannot be washed out of the hair.
- aromatic dye precursors e.g. p-phenylene-diamine and o-aminophenol
- H 2 0 2 hydrogen peroxide
- colour builder oxidising agent
- Dyeing compositions comprising H 2 0 2 are often referred to as "lightening dyes" due to the bleaching effect of H 2 0 2 .
- H 2 0 2 damages the hair. Further, oxidative dyeing often demands high pH (normally around pH 9-10), which also inflicts damage on the hair and irritation to the scalp. Consequently, it is not recommendable to dye the hair too often with dye compositions comprising H 2 0 2 .
- EP patent No. 0504005 (Perma S.A.) concerns compositions for dyeing hair which do not require the presence of H 2 0 2 .
- the compositions comprise an enzyme capable of catalyzing the formation of polymeric dyes and also dye precursors, such as bases and couplers, in a buffer solution wherein the pH of the composition is between 6.5 and 8, the enzyme having an optimal activity in this pH range.
- Rhizoctonia praticola laccase and Rhus vernicifera laccase have a pH-optimum between 6.5 and 8 and can be used to form the polymeric dyes according to this patent.
- the object of the present invention is to provide improved enzyme-based compositions for bleaching or dyeing of hair and other keratinous fibres, in particular compositions which provide the advantages made possible by use of oxidative enzymes, e.g. reduced damage to hair, but which at the same time result in an improved uniformity of the hair dyeing effect.
- hair dyeing compositions comprising an oxidation enzyme and a foaming agent result in improved uniformity of the dyeing effect, in particular an improved dyeing of the parts of the hair removed from the air interface.
- foam compositions of the invention serve to provide oxygen for the enzymatic oxidation process to parts of the hair that would otherwise rapidly suffer from an insufficient supply of oxygen, thereby ensuring that oxidation can proceed more uniformly throughout the hair.
- a more uniform hair dyeing is obtained, with reduced variation in hair colour intensity between different areas of the hair.
- the invention thus relates to an enzymatic foam composition adapted for dyeing of keratinous fibres, comprising 1 ) at least one oxidation enzyme, 2) at least one foaming agent, 3) at least one dye precursor and optionally 4) at least one modifier.
- Another aspect of the invention relates to a method for dyeing keratinous fibres, comprising contacting the fibres with the enzymatic foam composition for a period of time and under conditions sufficient to permit oxidation of the dye precursor to a coloured compound
- a further aspect of the invention relates to the use of the enzymatic foam composition for oxidative dyeing of keratinous fibres, in particular hair, fur, hide or wool.
- Figure 1 shows the effect on colour uniformity by dyeing with a foam formulation of the invention (See Example 1 )
- the first and second columns shows the Coefficient of Variance (CV) (determined as ⁇ L* and ⁇ E*) for a dyeing composition comprising foam SDS-Betaine-pPD-Laccase;
- the third and fourth columns show the CV of a dyeing composition comprising foam SDS-pPDP-Laccase;

BACKGROUND OF THE INVENTION Hair is often dyed to cover grey hair that appears with age. Further, during the last few decades, hair dyeing has become more and more popular in the western world for purely cosmetic purposes, i.e. the hair is dyed a different colour than its natural colour in order to obtain a desired "look" .
In general, hair dyeing compositions on the market today can be divided into three main groups:
- temporary hair dyes,
- semi-permanent hair dyes, and
- permanent oxidative hair dyes.
The temporary hair dyes are only intended to change the natural hair colour for a short period of time and usually function by depositing dyes on the surface of the hair. Such hair dyes are easy to remove with normal shampooing.
When using semi-permanent hair dyes the dyed colour can survive for five or more shampooings. This is achieved by using dyes having a high affinity for hair keratin and which are able to penetrate into the interior of the hair shaft. Permanent hair dyes are very resistant to sunlight, shampooing and other hair treatments and need only be refreshed about once a month as new hair grows out. With these dyeing systems, the dyes are created directly in and on the hair. Small aromatic dye precursors (e.g. p-phenylene-diamine and o-aminophenol) penetrate deep into the hair, where they are oxidised by an oxidising agent to coloured polymeric compounds. These coloured compounds are larger than the dye precursors and cannot be washed out of the hair.
By including compounds referred to as modifiers (or couplers) in the hair dyeing composition, a number of hair colour tints can be obtained. Catechol and Resorcinol are examples of such modifiers.
Traditionally, H202 (hydrogen peroxide) has been used as the oxidising agent (colour builder), but also as a bleaching agent. Dyeing compositions comprising H202 are often referred to as "lightening dyes" due to the bleaching effect of H202.
The use of H202 in dye compositions has some disadvantages, however, as H202 damages the hair. Further, oxidative dyeing often demands high pH (normally around pH 9-10), which also inflicts damage on the hair and irritation to the scalp. Consequently, it is not recommendable to dye the hair too often with dye compositions comprising H202.
To overcome the disadvantages of using H202 it has been suggested to use oxidation enzymes to replace H202. US patent No. 3,251 ,742 (Revlon) describes a method for dyeing human hair by dye formation in situ. An oxidative enzyme is used for colour formation reactions at a substantially neutral pH (pH 7-8.5). Laccases, tyrosinases, polyphenolases and catacolases are mentioned as suitable oxidation enzymes.
EP patent No. 0504005 (Perma S.A.) concerns compositions for dyeing hair which do not require the presence of H202. The compositions comprise an enzyme capable of catalyzing the formation of polymeric dyes and also dye precursors, such as bases and couplers, in a buffer solution wherein the pH of the composition is between 6.5 and 8, the enzyme having an optimal activity in this pH range. Rhizoctonia praticola laccase and Rhus vernicifera laccase have a pH-optimum between 6.5 and 8 and can be used to form the polymeric dyes according to this patent.
The problem arises, however, when using such oxidation enzymes to dye keratinous fibrous such as human hair, that oxygen is the limiting factor in the enzymatic reaction, since the reaction proceeds relatively quickly, especially for laccases. This is especially the case with compositions having a relatively high viscosity, such as gels and mousses. As a result, the reaction proceeds extensively at the parts of the hair lying at the hair/air interface, since the laccase at the interface has access to an adequate supply of oxygen from the air. In contrast, the major portion of the hair lying below this interface, i.e. between the air and the scalp, does not have access to adequate oxygen for the enzymatic oxidation to proceed after exhaustion of oxygen present in the reaction media, whereby the reaction proceeds slower (or comes to a complete stop) and this part of the hair is dyed relatively little compared to the surface hair fibres.
Thus, when using oxidative enzymes for dyeing of hair, it would be desirable to obtain a more uniform and faster dyeing effect throughout the hair than that which can be obtained with the presently available hair dyeing compositions containing oxidative enzymes.
SUMMARY OF THE INVENTION
The object of the present invention is to provide improved enzyme-based compositions for bleaching or dyeing of hair and other keratinous fibres, in particular compositions which provide the advantages made possible by use of oxidative enzymes, e.g. reduced damage to hair, but which at the same time result in an improved uniformity of the hair dyeing effect.
It has now surprisingly been found that hair dyeing compositions comprising an oxidation enzyme and a foaming agent result in improved uniformity of the dyeing effect, in particular an improved dyeing of the parts of the hair removed from the air interface. Such foam compositions of the invention serve to provide oxygen for the enzymatic oxidation process to parts of the hair that would otherwise rapidly suffer from an insufficient supply of oxygen, thereby ensuring that oxidation can proceed more uniformly throughout the hair. As a result, a more uniform hair dyeing is obtained, with reduced variation in hair colour intensity between different areas of the hair.
In a first aspect, the invention thus relates to an enzymatic foam composition adapted for dyeing of keratinous fibres, comprising 1 ) at least one oxidation enzyme, 2) at least one foaming agent, 3) at least one dye precursor and optionally 4) at least one modifier. Another aspect of the invention relates to a method for dyeing keratinous fibres, comprising contacting the fibres with the enzymatic foam composition for a period of time and under conditions sufficient to permit oxidation of the dye precursor to a coloured compound
A further aspect of the invention relates to the use of the enzymatic foam composition for oxidative dyeing of keratinous fibres, in particular hair, fur, hide or wool.

DETAILED DESCRIPTION OF THE INVENTION
The composition of the invention comprising 1 ) at least one oxidation enzyme and 2) at least one foaming agent is in particular a composition adapted for dyeing keratinous fibres, e.g. hair, fur, hide or wool. For the dyeing of keratinous fibres, the composition of the invention further comprises 3) at least one dye precursor and optionally 4) at least one modifier. A preferred use of the composition is as a permanent dye for the dyeing of human hair.
The oxidation enzyme is an oxidoreductase, i.e. an enzyme classified under the Enzyme Classification number E.C. 1 (Oxidoreductases) in accordance with the
Recommendations (1992) of the International Union of Biochemistry and Molecular Biology (IUBMB)) which catalyses oxidoreduction reactions.
Within the group of oxidoreductases enzymes are preferred which catalyse the oxidation of a substrate (an electron or hydrogen donor) by acting on oxygen (02) and/or a peroxide as the acceptor. Such enzymes include enzymes classified within the enzyme classes comprising oxidases, including E.C. 1 .1 .3. E.C. 1 .2.3, E.C. 1 .3.3, E.C. 1 .4.3, E.C. 1 .5.3, E.C. 1 .7.3, E.C. 1 .8.3 and E.C. 1 .9.3, laccases and related enzymes in E.C. 1 .10.3, and peroxidases in E.C. 1 .1 1.
According to the invention three types of oxidoreductases are specifically contemplated: a) Laccases or related enzymes, which act on molecular oxygen and yield water (H20) without any need for peroxide (e.g. H202), b) Oxidases, which act on molecular oxygen (02) and yield peroxide (H202), and c) Peroxidases, which act on peroxide (e.g. H202) and yield water (H20). Also, enzyme systems which comprise a combination of more than one enzyme from a single group or from different groups among the three types of enzymes are contemplated. In the present specification, although reference will often be made to a single enzyme for the sake of simplicity, it is to be understood that the description is generally applicable to such combinations of more than one enzyme. Further, although the invention is generally described in terms of the preferred aspect relating to the
dyeing of hair, it is to be understood that the description is generally applicable to foam compositions according to the invention adapted for dyeing of other types of keratinous fibres.
Particularly preferred enzymes are laccases and related enzymes, the term "laccases and related enzymes" including enzymes comprised by the enzyme classification E.C. 1 .10.3.2 (laccases) and catechol oxidase enzymes comprised by E.C. 1 .10.3.1 , bilirubin oxidase enzymes comprised by the enzyme classification E.C. 1 .3.3.5 and mono-phenol mono-oxygenase enzymes comprised by the enzyme classification E.C. 1 .14.99.1 . Laccases are multi-copper containing enzymes that catalyze the oxidation of phenols and aromatic amines. Laccase-mediated oxidations result in the production of aryioxy-radical intermediates from suitable phenolic substrates; the ultimate coupling of the intermediates so produced provides a combination of dimeric, oligomeric, and polymeric reaction products. Certain reaction products can be used to form dyes suitable for dyeing hair. The laccase may be derived from a microorganism, e.g. a fungus or a bacteria, or a plant. Preferably, the laccase employed is derived from a fungus.

Examples of other dye precursors include amino benzoic acid compounds of the general formula 1
wherein
R is an amino, a mono - or disubstituted amino or OR', where R' is H, alkyl, alkenyl, alkynyl, halogenalkyl, nitro, benzyl, phenyl or substituted phenyl, X, Y and Z may each independently be hydrogen, alkyl, alkenyl, alkynyl, halogenalkyl, nitro, benzyl, phenyl, substituted phenyl, amino, hydroxy or mercapto with the proviso that at least one of the groups X, Y and Z is an amino group or a salt thereof. Compounds where R' is a methyl, ethyl or isopropyl ester are preferred.
In one embodiment, the oxidoreductase is used with the dye precursor directly to oxidise it into a coloured compound. The dye precursor may be used alone or in combination with other dye precursors.
However, it is believed that when using a diamine or an aminophenol as the dye precursor, at least one of the intermediates in the copolymerisation must be an ortho- or para-diamine or aminophenol. Examples of such are described in US patent No. 3,251 ,742 (Revlon), the contents of which are incorporated herein by reference. Optionally, the dyeing composition of the invention (especially hair dyeing compositions) also comprises a modifier (coupler) by means of which a number of colour tints can be obtained. Modifiers are normally used in hair dyeing compositions, as the colours resulting from hair dyeing compositions without a modifier are usually unacceptable for most people.
Modifiers are typically m-aromatic diamines, m-aminophenols, polyphenols, amino naphthalines or naphthols. The modifier (coupler) reacts with the dye precur- sor in the presence of the oxidative enzyme, converting it into a coloured compound. Examples of modifiers (couplers) include m-phenylene-diamine, 2,4-diaminoanisole, 1 - hydroxynaphthalene(α-naphthol), 1 ,4-dihydroxybenzene(hydroquinone), 1 ,5- dihydroxynapthalene, 1 ,2-dihydroxybenzene(pyrocatechol), 1 ,3-dihydroxybenzene (re- sorcinol), 1 ,3-dihydroxy-2-methylbenzene, 1 ,3-dihydroxy-4-chlorobenzene(4- chlororesorcinol), 1 ,2,3-trihydroxybenzene, 1 ,2,4-trihydroxybenzene, 1 ,2,4-trihydroxy- 5-methylbenzene, and 1 ,2,4-trihydroxytoluene.
Compositions according to the invention may in addition contain additives and excipients commonly used in hair-dyeing compositions and other cosmetic products, e.g. humectants, oils, thickening agents, antioxidants, buffers, preservatives, fragrances, colours, etc. In a second aspect, the invention relates to a method for dyeing keratinous fibres, in particular hair, fur, hide and wool, using a composition as described above. The dyeing method can be conducted with one or more dye precursors and optionally in combination with one or more modifiers. The amount of dye precursor(s) and other ingredients used in the composition of the invention for this purpose are in accordance with usual commercial amounts. Hair dyeing is typically carried out at or near room temperature, preferably around the optimum temperature of the enzyme being used, and at a pH in the range of from 3.0 to 9.0, preferably 4.0 to 8.5, especially 6.0 to 8.0. Suitable dye precursors and optional modifiers are described above.
Although it is contemplated that the method of the invention typically will be performed using a single pre-mixed composition applied to the hair or other fibres as a foam comprising the oxidation enzyme, the foaming agent, the dye precursor and the optional modifier in order to obtain the most uniform result, it is also contemplated that the method may alternatively be performed by mixing two or more separate compositions and/or ingredients in order to result in the desired foam composition containing all of the necessary ingredients.
The invention is further illustrated in the following non-limiting examples.
MA TERIALS AND METHODS
Except where otherwise stated, the materials and methods used were the following.
Materials
Hair:
6" De Meo Virgin Natural White Hair (De Meo Brothers Inc., USA)
Enzyme:
Laccase from Myceliophtora termophilia described in WO 95/33837 (available from Novo Nordisk Biotech, Inc.) Dosed as 0.1 mg enzyme per ml of reaction liquid.
Dye precursors: The dye precursors used were selected from the following:
p-phenylene-diamine (pPD) o-aminophenol (oAP)
Buffer: 0.1 M borate buffer, pH 7.0 with 60 ppm Ca+ +
Analytical Equipment: Minolta CR200 Chroma Meter Daylight bulb: 1000 LUX (D65)
Methods
Preparation of foam compositions
Foams are made using foam dispensers or a blender, the foam compositions being gently blended by stirring during production to avoid foam formation at that stage. The following formulations were used:
"Minimal type "
SDS 0.4%
Dye precursor 0.5% Buffer up to 100%
The enzyme is added to the formulation as 0.1 mg enzyme protein per ml dye solution.
"Simple type A " SDS 2.0%
Betaine phosphate 2.0%
Dye precursor 0.5%
Buffer up to 100%
The enzyme is added to the formulation as 0.1 mg enzyme protein per ml dye solution
Reference: "still water"
Because foam can only be applied in a maximum amount of about 2.5 g per g of hair, the precursor concentration in the reference is reduced by 50%:
Dye precursor 0.25%
Buffer up to 100%
The enzyme is added to the formulation as 0.1 mg enzyme protein per ml dye solution. A total of 5 ml of reference dye solution is added to the hair (Still water).
Assessment of hair colour
The quantitative colour of the hair wisps is determined on a Minolta CR200 Chroma Meter using the parameters L* ("0" = black and " 100" =white), a* ("-" =green and " + " =red) and b* ("-" blue and " + " yellow).
ΔL*, Δa * and Δb* are the delta values of L*, a * and b* respectively compared to L*, a* and b* of untreated hair (e.g. ΔL* = L*βamplβ - L*untrβatβd hair).
ΔE* is calculated as ΔE* = sq.root(ΔL*2 + Δa *2 + Δb *2) and is an expression for the total quantitative colour change.
EXAMPLES
Example 1
Hair dyeing composition comprising laccase formulated as a foam 1 gram hair wisps were dyed with foam formulations (prepared as described above) while hanging on a sloped metal plate. The foamed dye solutions were massaged into the hair wisps, whereas the reference solution was poured onto the wisps in a 150 ml glass beaker. 1 -2 g of dye formulation was administered on each hair wisp. The dyeing was performed for 30 minutes at a temperature of 30°C, two wisps being used for each formulation. After administration of the dye formulation, the wisps were hung on the mount and placed in a heating cabinet during the dyeing period. The reference was left untouched. After dyeing, the wisps were rinsed and washed once and then dried.
The results of dyeing with two different dye precursors using the two foam formulations mentioned above are shown in the Figures 1 and 2. Figure 1 shows the effect on colour uniformity by dyeing with a foam formulation containing the precursor pPD. The two above-mentioned foam formulations are each tested on two hair wisps, the dye uniformity being expressed as the "CV" (coefficient of variance) of ΔE* and ΔL* after measuring each hair wisp 1 2 times from tip to root.
Figure 1 clearly shows that the colour uniformity is better for the hair wisps dyed with the foam formulations. Their CV is significantly lower than for the hair wisps dyed in the "still water" reference solution.
The same effect is seen in Figure 2, where the dye precursor is oAP. In this case, only one hair wisp is shown for each formulation, and again the foam improves colour uniformity.

Cone: 0.9 mg e.p/ml formulation (e.p = active enzyme protein) Dye precursor: p-phenylene-diamine (PPD) or p-toluene-diamine (PTD)
Cone: 0.1 % formulation Buffer: 0.1 M Borate buffer, pH 7.0 with 60 ppm Ca+ +
Foam formulation: 0.02 g MiniRisk™ shampoo per ml formulation
MiniRisk™ contains 1 5% SDS
Methods
1) The precursor is dissolved in 0.1 M borate buffer for 15 min. under stirring.
2) MiniRisk™, 0.1 M borate buffer and enzyme are mixed gently.
3) The presursor is then added to the formulation and mixed gently. 4) The formulation foam is made using a foam dispenser.
5) The foam is applied in a maximum amount of about 2.5 g per g of hair by massaging it into the hair wisps.
6) The wisps are hung on a metal plate for 30 minutes at a temperature of 30 °C for dyeing. 7) After 30 minutes the hair is rinsed for 3 minutes, washed with MiniRisk™ shampoo for 1 5 sec, then rinsed again and air-dried overnight. 8) After drying the hair color is measured using a Minolta Chroma Meter, an untreated hair wisp being used as a reference.
The results are shown in Figure 3, in which it may be seen that hair dyeing is obtained with tyrosinase when combined with either PPD or PTD as a dye precursor. Although the ΔE value for PPD is somewhat higher than for PTD, it is still at an acceptable level, in particular in light of the fact that tyrosinase is generally not regarded as an enzyme that is suitable for hair colouring purposes. This example thus shows that when used according to the present invention, acceptable hair dyeing may be obtained with tyrosinase.
