[0001] Use of a natural occurring polyphenol as an oxidative coupler dye precursor in an oxidative hair colouring composition

[0002] Description

[0003] The presently claimed invention relates to the use of at least one natural occurring polyphenol (component (A)) having a molecular weight of at least 150 g / mol as an oxidative coupler dye precursor in an oxidative hair colouring composition, wherein the oxidative hair colouring composition comprises as further components at least one primary dye precursor (component (B)), and optionally at least one further oxidative coupler dye precursor (component (C)). Moreover, the presently claimed invention relates to an oxidative hair colouring composition comprising at least one natural occurring polyphenol (component (A)) having a molecular weight of at least 150 g / mol used as an oxidative coupler dye precursor. Another aspect of the presently claimed invention relates to a kit comprising a tint composition comprising components (A), (B), and optionally (C), and a method of treating hair using the oxidative hair colouring composition.

[0004] BACKGROUND OF THE INVENTION

[0005] Oxidative hair colouring is known since years. Consumers want to be able to colour their hair to many shades, while still having a pleasant and safe usage experience. This requires high lift of hair to deliver a wide range of shades with low or acceptable hair damage while having low or no ammonia smell during the application. In order to deliver a wide range of shades, a large number of dye precursors are used, and they need to be used at sufficient levels to achieve the desired shades.

[0006] Permanent and demi-permanent oxidative hair colouring products have been used in professional salons and in retail products for use at home for decades. Colouring products typically comprise a tint composition and an oxidizing composition which are packaged separately and mixed immediately before use to form the colouring composition. The tint composition contains so-called oxidative dye precursors which are small molecules (typically oxidative primary dye precursors and oxidative coupler dye precursors) and an alkalizing agent, usually ammonia or an amine. These primary oxidative dye precursors react with the oxidative coupler dye precursors in the presence of an oxidizing agent to form larger, coloured dye products within the hair. The oxidizing composition contains the oxidizing agent to enable the colouring process. The oxidizing compositions typically contain a stabilized form of hydrogen peroxide and are sometimes referred to as the developer compositions.

[0007] The tint composition is thus mixed with the oxidizing composition immediately prior to the application to the hair to be coloured and the resulting mixture of the colouring composition is applied and left on the hair usually for 5 to 50 minutes before rinsing. The mixed colouring composition usually has an alkaline pH between about 8.5 and 10.5.

[0008] Oxidative hair colouring compositions comprising ammonia or an amine as alkalizing agent within the tint composition are often referred to as permanent hair colourants or "Level 3" hair colourants. Permanent hair colourants are for example marketed under the Koleston Perfect® brand name by Wella Professional in Europe.

[0009] Hydrogen peroxide, especially in the presence of an alkalizing agent, is capable of bleaching melanin, so that it is possible to obtain shades which are lighter or darker than the natural colour.

[0010] Demi-permanent hair colourants, also referred to as "Level 2" colourants, are also typically marketed as two-component systems. They also use oxidative primary dye precursors and oxidative coupler dye precursors as used in permanent hair colourants but differ in their use of alkalizing agents other than ammonia, in particular monoethanolamine (MEA) or aminomethylpropanol (2-amino-2-methylpropan-1-ol I AMP), and usually function at lower concentrations of hydrogen peroxide, typically 1 to 3 weight % (wt.%) in the mixed colouring composition compared to 3 to 6 or even higher wt.% for permanent "Level 3" colourants. Higher levels of hydrogen peroxide are, however, sometimes used when higher levels of colouring are sought (up to 8 wt.% hydrogen peroxide on the head for some shades).

[0011] Demi-permanent hair colourants usually cause less melanin bleaching and thus less lift (i.e., removal) of natural hair colour. The resulting dyes may also penetrate less deeply in the hair shaft so that demi-permanent hair colourants can be less long lasting than permanent hair colourants. On the other hand, demi-permanent hair colourants are usually also less damaging to the hair structure than permanent hair colourants and the resulting hair colour may also be more natural looking. A further advantage is that demi-permanent hair colouring compositions do not have the strong ammonia smell of permanent hair colouring compositions and thus have a better consumer experience. A professional brand of demi-permanent hair colourants in Europe is for example Colour Touch® from Wella Professional in Europe. The mixed colouring composition usually has an alkaline pH of between about 8.5 and 10.5.

[0012] To create a large variety of different shades in the state of the art generally oxidative hair colouring compositions comprising a combination of different oxidative coupler dye precursors and oxidative primary dye precursors are used.

[0013] There is a need for providing further compounds that can be used as oxidative coupler dye precursors in oxidative hair colouring compositions.

[0051] Furthermore, the terms "(a)", "(b)", "(c)", "(d)" etc. and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and that the embodiments of the subject matter described herein are capable of operation in other sequences than described or illustrated herein.

[0052] The term “about”, when used in relation to a weight ratio or a weight percentage, means that a specific value should be understood as meaning a range of ± 10 %. For example, the weight proportion of a compound of about 1 %, means a weight proportion ranging from 0.9 to 1.1 %. For example, the weight proportion of a compound of about 2.5 %, means a weight proportion ranging from 2.25 to 2.75 %. In another embodiment the term “about” can mean the exact value.

[0053] In the following passages, different aspects of the subject matter are defined in more detail. Each aspect so defined may be combined with any other aspect or aspects unless clearly indicated to the contrary. In particular, any feature indicated as being preferred or advantageous may be combined with any other feature or features indicated as being preferred or advantageous.

[0054] Reference throughout this specification to "one embodiment" or “preferred embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the presently claimed invention. Thus, appearances of the phrases "in one embodiment" or “in a preferred embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment but may refer to different embodiments of the presently claimed invention. Furthermore, the features, structures or characteristics may be combined in any suitable manner, as would be apparent to a person skilled in the art from this disclosure, in one or more embodiments. Furthermore, while some embodiments described herein include some, but not other features included in other embodiments, combinations of features of different embodiments are meant to be within the scope of the subject matter, and form different embodiments, as would be understood by those in the art.

For the avoidance of doubt, the applicant shall be entitled to any equivalents according to applicable law. For the purposes of the presently claimed invention, '% by weight’ or ‘wt.% ‘as used in the presently claimed invention is with respect to the total weight of the oxidative hair colouring composition. Further, the sum of wt.% of all the compounds (components), as described herein, in the respective compositions add up to 100 wt.%.

[0056] Every document cited herein, including any cross referenced or related patent or application, is hereby incorporated herein by reference in its entirety unless expressly excluded or otherwise limited. The citation of any document is not an admission that it is prior art with respect to any invention disclosed or claimed herein or that it alone, or in any combination with any other reference or references, teaches, suggests, or discloses any such invention. Further, to the extent that any meaning or definition of a term in this document conflicts with any meaning or definition of the same term in a document incorporated by reference, the meaning or definition assigned to that term in this document shall govern.

[0057] The measurement techniques described hereinabove and hereinafter are well known to a person skilled in the art and therefore do not limit the presently claimed invention.

[0058] By “oxidative hair colouring composition”, it is meant a ready-to-use composition which can change the colour of hair on which it is applied, and which preferably comprises an alkalizing agent, an oxidizing agent and oxidative dyes (oxidative coupler dye precursor and oxidative primary dye precursor).

[0059] By “two-component” oxidative hair colouring composition it is meant an oxidative hair colouring composition which is obtained by mixing shortly before use two compositions: a tint composition and an oxidizing composition. The tint composition comprises the oxidative primary dye precursors, oxidative coupler dye precursors and the alkalizing agent. The oxidizing composition comprises the oxidizing agent. The term “two-component oxidative hair colouring composition” and the term “oxidative hair colouring composition” in the present case are used synonymously.

[0060] By "composition" it is meant a composition which is mixed by the user with one or more other composition for preparing the ready-to-use oxidative hair colouring composition to be applied to the hair. Hereinafter, the “hair colouring composition” refers to a use / mixed hair colouring composition. By "user" it is meant the person preparing the hair colouring composition. The user is for example a professional hair stylist working in a salon and is different from the subject on whose hair the composition is applied, or the user is identical to the person on whose hair the composition is applied. The mixing can take place in a bowl or within a bottle or even through a mixer placed between the stored individual compositions and the point at which it is dispensed to be used. While two component oxidative hair colouring compositions are the most commonly found in the market, there are also others which use three or more components. For example, these colouring compositions comprise a tint composition and a separate alkali composition both of which are mixed in combination with the oxidizing composition to produce the colouring composition. In such a three-component system, the tint composition and the alkali composition are considered to be equivalent to the tint composition of a two-component system.

[0061] Alternatively, a tint composition, an anhydrous oxidizer composition and an aqueous composition can be mixed with the anhydrous composition to create the finished mixed colouring composition with the tint composition. In such a three-component system, the anhydrous oxidizer composition and the aqueous composition form the oxidizer composition of the two-component system. An anhydrous dye powder, tablet or granule can also be mixed with an aqueous alkali composition and an oxidizing composition.

[0062] Those skilled in the art are aware that there are multiple combinations of the components that can be interchanged to obtain the final mixed oxidative hair colouring composition. All these combinations are within the scope of the presently claimed invention which is exemplified in a non-limiting way.

[0063] By "lift" (or "lift power") it is meant the amount of lightening caused by the bleaching of the natural hair pigment melanin by using the oxidative hair colouring composition of the presently claimed invention. The amount of lift provided by different oxidative hair colouring compositions can be compared by using a human natural dark hair sample (e.g., dark hair of an individual of Chinese descent) and measuring the change of colour achieved following application of the compositions. The change in colour can be measured using well known parameters such as L*a*b* values. A composition can be said to provide a higher lift than another composition, when the resulting L* value or the so-called dL* value (given by L*final - L*initial) measured for a given treated sample of dark hair is higher for that composition than for the other composition, using the same experimental conditions. The denomination Level 2 (herein used interchangeably with "demi-permanent" or "tone-on-tone") and Level 3 (herein used interchangeably with "permanent") are commonly used in the hair colour trade to differentiate compositions with medium and high lift.

[0064] By "oxidizing agent" it is meant an electron accepting compound suitable for use in hair colouring compositions for removing the natural colour of hair (by destroying the melanin pigment) and reacting with oxidative primary dye precursors to enable the reaction with the oxidative coupler dye precursors to form the colour dye products. The most commonly used oxidizing agent in the art is hydrogen peroxide, however further suitable oxidizing agents that can be used in combination with hydrogen peroxide are described below. Oxidizing agents also include those which produce hydrogen peroxide when contacted with water. For example, sodium percarbonate, sodium perborate and urea peroxide can be used as anhydrous materials, which when contacted with water release hydrogen peroxide. For such oxidizing agents which product hydrogen peroxide when contacted with water, the wt.% of hydrogen peroxide within mixed colouring composition is considered as the level of oxidizing agent (E).

[0065] As it follows from the above, an oxidative primary dye precursor is a compound, such as an aromatic diamine compound, that forms - when oxidized by the oxidizing agent - reactive intermediates. In turn, the so formed reactive intermediates react with an oxidative coupler dye precursor, such as resorcinol or in accordance with the present invention a natural occurring polyphenol having a molecular weight of at least 150 g / mol, so as to form a colored dye molecule.

[0066] By "alkalizing agent" it is meant one or more compounds suitable for raising the pH to alkaline level in mixed colouring compositions, in particular to a pH in the range of > 8.5 to < 10.5. Generally, the most commonly used alkalizing agents in the art are ammonia and monoethanolamine, however in the presently claimed invention also alkalizing agent other than ammonia (herein “nonammonia, non-monoethanolamine” alkalizing agent), can be used. The alkali agent is preferably used to raise the pH of the mixed colouring composition to a pH in the range of > 8.5 to < 10.5.

[0111] The oxidizing agents are preferably water-soluble inorganic peroxide materials which are capable of yielding hydrogen peroxide in an aqueous solution.

[0112] In one embodiment of the presently claimed invention, the at least one oxidizing agent is selected from the group consisting of hydrogen peroxide, inorganic alkali metal peroxides (such as sodium periodate and sodium peroxide), organic peroxides (such as urea peroxide, melamine peroxide), inorganic perhydrate salt bleaching compounds (such as the alkali metal salts of perborates, percarbonates, perphosphates, persilicates, persulphates), and mixtures thereof; preferably from the group consisting of hydrogen peroxide, persulphates, and mixtures thereof; most preferably the oxidizing agent is hydrogen peroxide.

On the other hand, the different components of the invention, in particular the third component, may be sold separately from the other components.

[0175] Method of Hair Dying

[0176] Application of the oxidative hair colouring composition to the hair may be undertaken in several ways. Application of the oxidative hair colouring composition may take place on the whole head of hair of an end user. As used herein, the "whole head of hair" means that the hair all over the head from the root of the hair to the tip of the hair is included in the application process. By contrast, the application of the oxidative hair colouring composition may take place only on the root portion of the hair. The application to the root portion of the hair may still be over the entire head of the end user, but application of the oxidative hair colouring composition is applied only to the section of hair closest to the head (root portion), which is between about 0.01 mm to about 40 mm from the scalp of the head. After application to the root portion, product may be applied to the rest of the hair at a later stage to prevent over processing of the hair in the lengths and ends. Also, application may take place on a portion of hair. Application of a portion of hair is commonly referred to as highlighting or lowlighting. The portion of hair may be physically separated from the whole head of hair in a hair bundle or may be a smaller portion of hair than the whole head of hair. A hair bundle may be physically separated from a whole head of hair by a device including a plastic cap through which hair bundles are formed when hair is pulled through orifices in the plastic cap, metal foils encompassing a hair bundle, strand separators applied to hair at the root portion, or similar devices.

[0177] When present, an optional conditioning agent can be provided in an additional container. In the latter case, the conditioner can be mixed immediately before use and applied together with the other components, or the content of the additional container can be applied (after an optional rinse step) as a posttreatment immediately after the oxidative hair colouring composition.

[0178] According to one method for oxidatively colouring hair, the method comprises mixing a tint composition and an oxidizing composition and optionally a third component comprising a second non-ammonia alkalizing agent together to form a oxidative hair colouring composition, applying the oxidative hair colouring composition to the hair to form a treated hair surface, waiting for a period of 5-50 minutes, such as 20-35 minutes, and then removing the hair colouring composition from the treated hair surface through rinsing with water.

[0179] The methods of colouring hair also may further comprise working the oxidative hair colouring composition into the treated hair surface by hand or by a tool for a few minutes to ensure uniform application to the entire treated hair surface. The oxidative hair colouring composition remains on the treated hair surface while the end hair colour develops for a time period of 5 to 50 minutes to form oxidatively coloured hair. The consumer then rinses his / her oxidatively coloured hair thoroughly with tap water and allows it to dry and / or styles the oxidatively coloured hair. In one embodiment of the presently claimed invention, a method of treating hair with the oxidative hair colouring composition preferably comprises the steps of:

[0180] a. providing a tint composition as described herein;

[0181] b. providing an oxidizing composition as described herein;

[0182] c. mixing the oxidizing composition and the tint composition to obtain a mixed oxidative hair colouring composition as described herein;

[0183] d. applying the mixed oxidative hair colouring composition for the oxidative dyeing of keratin fibres onto the hair;

[0184] e. leaving the composition on the hair for 5 to 50 minutes; and

[0185] f. subsequently rinsing the oxidative hair colouring composition from the hair.

[0186] In one embodiment of the presently claimed invention, the oxidative hair colouring composition may be obtained by mixing immediately prior to use a tint composition and the oxidizing composition. A sufficient amount of the mixed oxidative hair colouring composition is applied to the hair, according to the hair abundance, generally from 20 to 250 grams depending on the amount of hair to be coloured. Upon such preparation, the oxidative hair colouring composition is applied to the hair to be dyed and remains in contact with the hair for an amount of time effective to dye the hair. Typically, the oxidative hair colouring composition is allowed to act on the hair from 5 to 50, preferably 10 to 40, preferably 20 to 35 minutes, at a temperature ranging from 15 to 50 °C. Thereafter, the hair is rinsed with water to remove the oxidative hair colouring composition and dried. If necessary, the hair is washed with a shampoo and rinsed, e.g., with water or a weakly acidic solution, such as a citric acid or tartaric acid solution, and dried. Optionally, a separate conditioning product may also be provided.

[0187] The oxidative hair colouring composition can be applied on hair via an applicator bottle or brush. It can be used on full head or partly on single strands (highlight application) as common highlight applicator foils, caps and special applicators can be used, but also freehand techniques such as balayage, with brush and / or combs can be possible. The oxidative hair colouring composition can also be applied as a mousse via a manual spray, a pressurized container or an aerosol mousse. The oxidative hair colouring composition may be dispensed as a solid form to which water is added to generate the oxidant and form a thickened vehicle suitable for hair colouring.

[0188] The invention is associated with one or more of the following advantages: • high lift of the hair

[0189] • a wider range of desired colour shades for colouring the hair

[0190] • low levels of damage of the hair

[0191] • a pleasant odour profile while application to the hair

[0192] • reduced levels of dye adducts

[0193] • less off-tone

[0223] EXAMPLES

[0224] The following examples illustrate the formulations and performance results of oxidative hair colouring composition according to the presently claimed invention. These examples are not intended to be inclusive of all aspects of the subject matter disclosed herein, but rather to illustrate representative compositions and results. These examples are not intended to exclude equivalents and variations of the presently claimed invention, which are apparent to one skilled in the art.

[0225] Hair tresses used for testing

[0226] Buffalo hair was purchased (Kerling International Haarfabrik GmbH, Backnang, Germany) in the form of 8cm long and 1 cm wide tresses. Method of applying oxidative hair colouring composition to hair

[0227] All products and equipment for the hair dye-out were equilibrated to 30 °C in a circulation oven overnight. The tint compositions C1 to C4 according to table 1 were prepared. Moreover, the oxidizing composition 01 according to table 2 was prepared. Equal weights (approximately 4 g each) of the tint compositions (C1 to C4) and the oxidizing composition (01) were mixed in a plastic bowl using a dye-out brush, to obtain the oxidative hair colouring compositions (C101 , C2O1 , C3O1 , and C4O1 ) as claimed in the presently claimed invention.

[0228] The hair tress was placed on a plastic plate and about 2g of colouring composition was applied to the free hair portion of a tress and the colour developed at 30°C for 30 minutes in a 30°C air circulation oven. After colour development and removal from the oven, excess colouring composition is squeezed out from the tress by hand, wearing nitrile gloves and the tress washed in 4 L min water at 37 C for 2 min. The hair is then blow dried.

[0229] The L* value (lightness value), a* (green to red component value) and b* (blue to yellow component value) of hair swatches colored with each of the hair coloring composition C1, C2, C3 and C4 was measured using a Minolta 2600d spectrophotometer.

[0230] The formulations were prepared according to the following methods:

[0231] Tint compositions:

[0232] The components of the tint compositions for each product were dissolved in about 80m L of water and added exactly in the order of positions according to Table 1. This way the antioxidants are added first which prevent the polyphenols from getting air oxidized. Then when the oxidative primary precursor (position 4) and the polyphenols (positions 5 and 6) are added, the solution becomes cloudy. Sodium hydroxide (position 7) is gradually added to completely neutralize the polyphenols. The quantity of sodium hydroxide is calculated to neutralize three phenolic groups on resveratrol and 4 phenolic groups on quercetin. After complete addition of sodium hydroxide the solution becomes clear. Finally, ammonia (position 8) is added and the rest of the water (position 9) to bring the total composition to 100g. The resulting solution is used for coloration right away.

[0235] q.s : quantity sufficient

[0236] Oxidizing composition:

[0237] Creme pre-mix formula was a part of the oxidizing formulation. A creme pre-mix is created by combining positions 9 to 11 in Table 2 for the oxidative composition. The Creme pre-mix formula was heated to 80 to 85 °C to melt the waxes and surfactant with stirring. The composition was homogenized for 5 minutes and then cooling was started to reduce the product to room temperature. The resulting creme pre-mix was thick and used in the preparation of oxidizing composition (01).

[0238] The components 1 to 7 of table 2 were mixed together with water at room temperature. When all of the materials were dissolved, 20 wt.% of the creme pre-mix was added, and the mixture stirred until a uniform consistency was obtained. The oxidizing composition was then stored in plastic bottles until used.

[0243] Table 3: Measured color L* a * b* values

[0244]

[0245] The colored tresses were first visually inspected. The tresses colored with the oxidative hair colouring compositions C1O1 and C3O1 were colored, while the tresses colored with the oxidative hair colouring compositons C2O1 and C4O1 remained white. The color was yellow with some tinge of brown. The exact color values for the colored tresses are reported in Table 3.

[0246] Since tint composition C1 shows a colored hair result in the presence of an oxidative primary precursor, we can conclude that resveratrol takes part in the color forming reaction and can be considered as an oxidative coupler precursor. Without the oxidative primary precursor in composition C2, resveratrol does not give any color on a buffalo hair tress.

[0247] Tint composition C3 shows a colored hair result in the presence of an oxidative primary precursor, we can conclude that quercetin takes part in the color forming reaction and can be considered as an oxidative coupler precursor. Without the oxidative primary precursor in composition C4, quercetin does not give any color on a buffalo hair tress.
