Description

METHOD FOR FAST HAIR DYEING FIELD OF THE INVENTION The present invention relates to a method for decolorization and rapid coloring of keratinous fibers.

BACKGROUND OF THE INVENTION The permanent alteration of the color of the keratinous fibers, in particular the human hair, by means of the application of hair dyes is well known. To provide the consumer with the desired hair color and hair color intensity, a very complex chemical process is used. Formulations for permanent hair dyeing usually comprise oxidative hair dye precursors, which can diffuse into the hair through the cuticle and into the cortex where they can react with each other and other suitable oxidizing agents to form the dye molecules final. The resulting molecules have a larger size and therefore are unable to easily diffuse out of the hair during the subsequent washing with water and / or detergents; therefore they provide a permanence of the color desired by the consumer. The reaction is usually carried out in an aggressive environment of about pH 10 in the presence of an alkalizing agent and an oxidizing agent. In addition, the consumer repeats this process regularly to maintain the tone and intensity of hair color and to ensure continuous and even coverage of the hair, including the coverage of new hair growth. However, despite the fact that commercial products for the Hair dyeing has been available for many years, the product still exhibits many deficiencies related to the use by consumers. In particular, the application of products for dyeing the hair is still a process that consumes a relatively long time and the consumer may take more than an hour to mix, apply, wait for the color to develop and remove the product, before drying and returning. to comb For most consumers, the process of hair dyeing is a regular part of their beauty routine; therefore, it would be highly convenient to reduce the time needed to dye the hair while maintaining the other requirements that include ease of application, low odor and especially the supply of the desired hair color, particularly for consumers seeking changes and / or significant levels of increase in the color obtained. Several attempts have been described in the literature to reduce the time of application necessary to dye the hair, for example, by the use of oxidative hair dye or bleaching compositions comprising carbonate. For example, WO01 / 28508 discloses hair coloration and discoloration compositions comprising an oxidizing agent, hair coloring agents and carbonate and / or ammonium carbamate that improves discoloration and discoloration with low odor and damage to hair without need of using buffering agents, pH modifiers or hair bulking agents. The compositions are applied to the hair for a period of time from 1 to 60 minutes. French patent FR1592939 describes a composition for dyeing hair comprising oxidizing dyes, ammonium carbonate and hydrogen peroxide with a pH 7-9 which provides an effective dyeing in a fairly short period of time. European patent EP435012 discloses compositions for hair dyeing that require a short period of dyeing, cause little damage to the hair and do not produce irritating odor after dyeing, comprising a carbonate source, an alkaline hydrogen peroxide that generates no odor and a buffer solution. Also, European patent EP1106166 discloses hair dyeing compositions comprising ammonia, carbonate (other than the ammonia salt), transition metal salt and chelating agent, which do not give off an irritating odor, produce little irritation to the skin and They can change the hair color to a lighter shade in short time. Patent WO04 / 014328 describes in one step compositions for hair coloring comprising peroxide oxidizing agents, specific oxidizing agents and at least one water-soluble salt that releases carbonate, which provide color with greater efficiency and are applied for a period of 2 to 60 minutes. Other attempts have been described in U.S. Pat. no. 6,703,004 which discloses hair bleaching compositions comprising an aqueous oxidizing agent, persulfate and a hydrophilic oil, in amounts sufficient to provide a mixture containing 3-5% active oxygen and 0.7-1.2 meq / g alkalinity, wherein the composition It can discolor hair in 10 to 30 minutes. Also, the U.S. patent no. No. 6,669,933 discloses an aqueous coloring composition for oxidative hair coloring in less than 12 minutes comprising a mixture of dye and developer, a free alkalinity concentration of 0.2-0.75 meq / g and hydrogen peroxide. U.S. Pat. no. 2004/0078906 describes a process for rapidly dyeing and decolorizing keratin by means of which a specific direct dye is applied to fibers in which less than 5 minutes is left. Other attempts to reduce the application time of hair dyes on the head involve methods that require short consecutive treatments with hair dyes by means of which the color change is gradually obtained after a time. For example, WO01 / 76546 describes a method of hair coloring which comprises the steps of applying to the hair a composition that alters the color thereof and leaving it in the hair for approximately 0.5 to 15 minutes, wherein this method is repeated from once a month to approximately 3 times a day. U.S. Pat. no. 2003/0154561 describes a method for applying an oxidative shampoo for a period of time from 5 seconds to 5 minutes, wherein the treatment is repeated from 2 to 30 times and the time interval between treatments is from 8 hours to 30 days. Also, the U.S. patent no. 2004/0098814 discloses a method of permanent dyeing, wherein the hair is subjected to a number of consecutive short treatments comprising a dye intermediate in a shampoo or conditioner base, a water soluble salt that releases carbonate and an ammonium salt soluble in water. U.S. Pat. no. 2004/0098816 also discloses a method for the gradual permanent coloration of the hair by which the hair is subjected to several treatments spaced apart for a given period of time, wherein the treatment compositions comprise ammonium carbonate combined with a chelant. However, none of these documents successfully addresses the problems associated with the rapid delivery of color to hair. In particular, the problem of hair damage caused by the use of high concentrations of hydrogen peroxide and ammonia to provide the required increase and color, and similarly, the scalp irritation problem also generally produced by a high concentration of Hydrogen peroxide and ammonia and also the high pH value are not satisfactorily resolved with the technologies and products currently marketed. Another critical problem related to the fast coloration compositions of the prior industry is the delivery of the desired resultant color and also the Effective coverage of gray hair whose quantity and distribution vary considerably among different consumers. The previous industry does not provide the necessary tone and depth of color or meet the needs of consumers who want to clarify the color of their hair at various levels of increase. To significantly lighten the hair it is necessary to decolorize it considerably and this is currently only achieved by using compositions comprising high levels of hydrogen peroxide and which are used on the hair for a prolonged period of time for the consumer to obtain the desired color. Also, the compositions of the prior industry also do not provide the hair with a uniform and uniform color or maintain the initial color coverage obtained during the washing and drying cycle after dyeing. Therefore, it would be desirable to also provide the consumer with a hair colorant that provides the desired levels of increase and rinsing, as well as a better color supply and less damage, less irritation of the skin and scalp and little odor, which be effective for shorter application time periods than currently available products and that can be used as part of a consumer's usual beauty care routine. In addition, it would also be desirable to provide a rapid color supply system that solves the problem of rapid but adequate application of the composition to the hair. It has now been surprisingly discovered that oxidative hair coloring compositions comprising an oxidizing agent, a carbonate ion source and an alkalizing agent at pH 9.5 and below provide a fast-acting decolorizer or dye for the hair that provides the desired color in a development time less than 20 minutes in the hair of the consumer, at the same time that it supplies the desired color as that supplied by ammonia / peroxide systems currently used that require a waiting time of 45 minutes. further, the method of the present invention reduces damage to the hair, reduces irritation of the skin and scalp, has low odor and is compatible with the current dye and dye precursor systems, and this produces an improvement in the increase and clarification of the blond tones, an optimal deposition of the dye, uniformity and color, in particular gray hair coverage, which is maintained through the washing and styling cycles of the consumers until the next coloring treatment. The method also allows the rapid application of the compositions to the hair and minimizes the staining of the skin of consumers, in particular by the hairline, while still supplying the desired color.

BRIEF DESCRIPTION OF THE INVENTION The present invention relates to a method for oxidative staining and discoloration of hair comprising the steps of supplying a composition comprising i) at least one source of peroxy monocarbonate ions and ii) at least one source of alkalizing agent, preferably ions ammonium, where that composition has a pH of up to 9.5, inclusive, and then apply that composition to the hair and retain that composition in the hair for a period of less than 20 minutes to then rinse that hair composition. In another aspect, the present invention relates to the use of a composition comprising i) at least one source of peroxy monocarbonate ions and ii) at least one source of alkalizing agent, preferably ammonium ions, wherein said composition has a pH of up to 9.5, inclusive, for oxidative coloring or discoloration of the hair in less than 20 minutes. Another aspect of the present invention relates to a sequential method of coloration or oxidative discoloration of the hair comprising the steps of applying at least two sequential treatments of coloration or oxidative discoloration of the hair, wherein the period of time between each treatment is from 1 day to 60 days, and wherein each treatment comprises the steps of providing a composition comprising i) at least one source of peroxy monocarbonate ions and ii) at least one source of alkalizing agent, preferably ammonium ions, wherein said composition has a pH less than 9.5 and then applying that composition to the hair and retaining that composition in the hair for a period of less than 20 minutes to then rinse that composition of the hair. Another aspect of the present invention relates to a method for pretreating the hair wherein a pretreatment composition comprising at least one conditioning agent that is retained on the hair prior to applying the dye or decolorizing composition to the hair is first applied to the hair.

DETAILED DESCRIPTION OF THE INVENTION Even though the specification concludes with the claims that in a particular manner clearly state and claim the invention, it is believed that the present invention will be better understood from the following description. As used herein, the term "hair" to be treated may well be "live", ie, that which is in a living organism, or "not alive", that is, that of a wig, a hairpiece or another aggregation of non-living keratinous fibers. Mammalian hair, preferably human hair is preferred. However, wool, skin or other fibers containing keratin are suitable substrates for the compositions according to the present invention.

All percentages are by weight of the total composition, unless specifically indicated otherwise. When more than one composition is used during a treatment, the total weight to be considered is the total weight of all the compositions applied simultaneously on the hair (i.e., the weight found "on the head") unless indicated by any another way. All proportions are proportions by weight, unless specifically indicated otherwise. The permanent hair coloring products currently marketed typically use a combination of an alkalizing system, dye precursors and an oxidant to deliver the desired hair color to the consumer. The alkalizing agent is generally ammonia or an alkanolamine, such as monoethanolamine and the oxidant is generally hydrogen peroxide or a solid form of hydrogen peroxide. The final color of the hair that is supplied to the consumer is a combination of the result of the underlying discoloration of the melanin pigment in the hair fiber and the supply of the chromophore portions of dye which are preformed, ie direct dyes, or which are they form through of the oxidation of the dye precursors within the fiber of the hair. The optimum pH for those systems normally has approximately pH 10.0. This high pH is necessary to produce a sufficient concentration of the perhydroxy anion (HOO-) to obtain the desired decolorization of the melamine. It has been discovered that below pH 9.5 the concentration of this species is less than 0.01% of the concentration of hydrogen peroxide added (pKa = 11.6) and the amount of melanin discoloration drops dramatically and therefore is insufficient to provide the desired final color. Nevertheless, as described above, the compositions that have a high pH cause many disadvantages observed by consumers of these coloring systems. In particular, the level of volatile ammonia increases at high pH (above pH 9.5) providing greater unpleasant odor. Also, some consumers suffer from irritation of the skin and scalp. In addition, the reactive species, including the perhydroxy anion, react with the hair fiber producing significant damage to the fiber. A consequence of this reactivity is that the hydrophilicity of the hair fibers increases significantly and this causes an increase in the force required to comb the hair as compared to the hair that has not been dyed. In addition, the greater forces that are exerted during styling and styling also increase the damage to the hair fibers. It has now surprisingly been found that a method for hair coloration and discoloration wherein a composition comprising the combination of at least one source of peroxy monocarbonate ions, preferably formed in place from a source of hydrogen peroxide and a carbonate ion source and at least one source of alkalizing agents, and preferably at least one source of radical scavenger, (as defined hereinafter), and preferably dyes and / or dye precursors, at a pH of up to 9.5, inclusive, preferably from 7.5 to 9.5, which is applied to the consumer's hair for a period of time less than 20 minutes can provide improvements in the results of the desired color for the hair, and at the same time considerably reduce the odor, Irritation of the skin and scalp and damage to hair fibers. Without theoretical limitations of any kind, it is believed that in the present invention the key species responsible for the discoloration of melanin, i.e., the peroxy ion monocarbonate (-OC (O) OOH), decomposes at pH values above 9.5 to form oxygen and the hydrogen carbonate ion. At pH values below 7.5 the Hydrogen carbonate ion decomposes to form carbon dioxide and water. At pH values of 9.0 the melanin discoloration and the final color observed is at an optimum level. In this way surprisingly the present invention allows the supply of greater increase, i.e. the lightening of the hair which is a very desirable necessity of the consumers. In addition, compositions having a pH below 9.5 have the benefit that not only the unpleasant odor of ammonia is significantly reduced, but fiber damage is also reduced. In addition, due to the kinetics of the carbonate system, the compositions are developed in the hair of the consumer's head in a short time of up to about 20 minutes to provide an improved uniform color which is maintained during the washing and styling cycle. The compositions according to the present invention thus comprise a source of peroxymonocarbonate ions. These ions are generally formed at the site of the reaction between a source of hydrogen peroxide and carbonate ion. Accordingly, the compositions according to the present invention comprise or are used in combination with a composition comprising at least one source of an oxidizing agent. Preferred oxidizing agents to be used herein are water soluble peroxygen oxidizing agents. "Soluble in water", as defined herein, means that under standard conditions at least 0.1 g, preferably 1 g, more preferably 10 g of the oxidizing agent can be dissolved in 1 liter of deionized water. Oxidizing agents are valuable for the initial solubilization and discoloration of melanin (discoloration) and accelerate the oxidation of oxidative dye precursors (oxidative staining) on the hair shaft.

Any source of these ions can be used. Suitable sources for use herein include sodium, potassium, guanidine, arginine, lithium, calcium, magnesium, barium, ammonium salts of carbonate, carbamate and hydrocarbon ions and mixtures thereof, such as sodium carbonate, hydrogen sodium carbonate, potassium carbonate, potassium hydrogen carbonate, guanidine carbonate, guanidine hydrogen carbonate, lithium carbonate, calcium carbonate, magnesium carbonate, barium carbonate, ammonium carbonate, ammonium hydrogen carbonate and mixtures of these. The percarbonate salts can also be used to provide both the carbonate ion source and the oxidizing agent. The preferred sources of carbonate ions, carbamate and hydrocarbon ions are sodium hydrogen carbonate, hydrogen hydrogen carbonate, ammonium carbamate and mixtures thereof. The compositions of the present invention may comprise from about 0.1% to about 15%, preferably from about 0.1% to about 10% by weight, more preferably from about 1% to about 8% by weight of the carbonate ion. If they are included in the composition, the weight ratio of the ammonium ions and the carbonate ions is preferably from 3: 1 to 1:10, more preferably from 2: 1 to 1: 5.

Any agent known in the industry can be used, such as alkanolamides, for example, monoethanolamine, diethanolamine, triethanolamine, monopropanolamine, dipropanolamine, tripropanolamine, 2-amino-2-methyl-1,3-propanediol, 2-amino-2-methyl- 1-propanol, and 2-amino-2-hydroxymethyl-1,3-propanediol and salts of guanidinium. In particular, the preferred alkalizing agents are those that provide a source of ammonium ions. Any source of ammonium ions is suitable for use in the present. Preferred sources include ammonium chloride, ammonium sulfate, ammonium nitrate, ammonium phosphate, ammonium acetate, ammonium carbonate, ammonium hydrogen carbonate, ammonium carbamate, ammonium hydroxide, percarbonate salts, ammonia and mixtures thereof. Particular preference is given to ammonium carbonate, ammonium carbamate, ammonia and mixtures thereof. The compositions of the present invention may comprise from about 0.1% to about 10% by weight, preferably from about 0.5% to about 6%, with the maximum preference of about 1% to about 3% of an alkalizing agent, preferably ammonium ions. pH In accordance with the method of the present invention, the compositions herein have a pH up to pH 9.5, inclusive. Preferably, the compositions of the present invention have a pH of from about 9.5 to about 7.5, more preferably from about 9.5 to about 8.4, with a greater preference from about 9.4 to about 8.5 and even more preferably about pH 9.0. Preferably, the compositions of the present invention are prepared in such a way that before application to the hair fibers, the pH of the composition is not greater than about pH 9.5. However, in another embodiment of the present invention, the compositions can be formulated in such a way that the pH is up to 9.5 during the period of time of application of the composition to the fibers of the hair before removing it from there. Preferably, the pH is up to about 9.5 by at least 50% of the time period, preferably at least 70%, more preferably at least 80% and most preferably at least 90% of the time period of application of the composition to the hair. The pH of the compositions can be determined using the Mettler Toledo MP220 pH meter or a MP225, equipped with a standard laboratory pH electrode. The equipment is calibrated before each use using standard calibration buffers and using the standard calibration procedure. For a good rinse and a good color formation, it is known that the final formulation must have good buffering capacity or reserve alkalinity (the ability of the system to resist the pH change that would otherwise be caused by the addition of acid). Reserve alkalinity is measured using a Mettler DL70 autotitator with 0.1 N methanolic hydrochloric acid which is added to 0.7 ml of well-mixed dye product in 50 ml of methanol. The electrode is calibrated and then used to measure the amount of acid needed to reach the maximum equivalence point triggered by a rapid pH change. Using this method it has been determined that a reserve alkalinity of at least 0.2 ml of 0.1 N ethanolic hydrochloric acid and preferably greater than 0.4 is necessary for good rinsing and coloring. Suitable pH regulating systems include mixtures of ammonium acetate / ammonia, monoethanolamine tetrasodium pyrophosphate, isopropanolamine, benzoic acid.

Some of these additional components are detailed below.

Hair dyes The hair coloring compositions of the present invention are preferably hair coloring compositions comprising oxidative dyeing compositions. These compositions comprise oxidative hair dye precursors (also known as primary intermediates) that will deliver a variety of hair colors to the hair. These small molecules are activated by the oxidizing agent and react with other molecules to form a larger colored complex on the hair shaft. The precursors may be used alone or in combination with other precursors, and one or more may be used in combination with one or more coupling agents. Coupling agents (also known as color modifiers or secondary intermediates) are usually colorless molecules that can form colors in the presence of activated precursors, and are used with other precursors or coupling agents to generate specific color effects or to stabilize the color. The choice of precursors and coupling agents will be determined by the color, tone and intensity of the coloration desired. In the present, precursors and coupling agents can be used, either alone or combined, to provide dyes that have a variety of shades, ranging from blond ash to black.

E. and Smith, R.M .: Constant Critical Stability, Vol. 1, Plenum Press, New York & London (1974) and Martell, A. E. and Hancock, R. D .: Metal Complexes in Aqueous Solution, Plenum Press, New York & London (1996), both incorporated herein by reference. Examples of chelants suitable for use herein include EDDS (ethylenediamineadisuccinic acid), carboxylic acids (in particular aminocarboxylic acids), phosphonic acids (in particular aminophosphonic acids) and polyphosphoric acids (in particular polyphosphoric acids). linear), their salts and derivatives. Chelants can be incorporated in the composition of the present invention as stabilizers and preservatives. further, it has been discovered that the chelators provide benefits for damage to hair fiber and therefore, can be used to further improve the hair damage profile of the present invention. The levels of chelants in the present invention can be as low as about 0.1%, preferably at least about 0.25%, more preferably about 0.5% for the most effective chelators such as the diamine-N.N'-dipolyzacid chelators and monoamide-N, N'-dipoly acid monoamine (e.g., EDDS). Less effective chelators are used more preferably at a concentration of at least about 1% and even more preferably higher than about 2% by weight of the composition, depending on the effectiveness of the chelant. Levels as high as approximately 10% may be used, but above this level significant problems may arise in the formulation.

Solvents Solvents suitable for use in the compositions of the present invention include, but are not limited to, water, butoxydiglycol, propylene glycol, (denatured) alcohol, ethoxydiglycol, isopropyl alcohol, hexylene glycol, benzyl alcohol and dipropylene glycol.

A preferred form for the compositions according to the present invention are thickened solutions comprising a salinity-tolerant thickener or oil-in-water emulsions.

Pretreatment compositions In accordance with one aspect of the method of the present invention, the hair is treated with a pretreatment composition prior to the application of the dyeing or bleaching compositions of the hair. The pretreatment compositions according to the present invention comprise at least one conditioning agent. As used herein, the term "conditioning agent" refers to any agent that has the function of improving at least one cosmetic property of keratin materials such as hair, for example, smoothness, smoothness, detangle, sensation and static electricity. The conditioning agent may be soluble or insoluble in water.

Any of the conditioning agents previously included herein as conditioning agents and surfactants may be suitable for use in the pretreatment composition. Especially preferred are cationic polymers, silicone materials, anionic polymers, nonionic polymers, oils and waxes, emulsions made with lamellar liquid crystals and mixtures thereof. Emulsions made with laminar liquid crystals that are formed by combining various active ingredients provide an improvement in the cosmetic properties of the composition, for example, in the conditioning properties. This occurs due to the presence of a combination of fatty materials and an emulsifier to form an emulsion. Emulsifiers for use in the continuous aqueous phase of the emulsion may include an anionic surfactant, cationic surfactant, amphoteric surfactant, water soluble polymer surfactant, surfactant comprising water soluble silicone, nonionic surfactant having an HLB greater than about 10, or a surfactant system capable of forming stabilizing liquid crystals.

Surfactants belonging to these classes are listed in McCutcheon's Emulsifiers and Detergents (McCutcheon's Emulsifiers and Detergents) ), North American and international editions, MC Publishing Co., Glen Rock NJ, pages 235-246 (1993). The emulsifier to be used in the aqueous phase does not gel the aqueous phase. However, the emulsifier may be capable of forming a stabilizing layer of laminar liquid crystals. To be more concise, the term "liquid crystal structure", as used herein, should also include gel networks, which are solidified liquid crystals. The surfactant system can be a single surfactant or a mixture of surfactants. In some cases, a particular surfactant can not form a liquid crystal structure by itself, but can participate in the formation of liquid crystals in the presence of a second surfactant. Illustrative classes of surfactants that can participate in the formation of a liquid crystal include, but are not limited to, cationic surfactants, anionic surfactants, nonionic surfactants, quaternary ammonium surfactants and specific lipid surfactants.

The pretreatment compositions preferably comprise a conditioning agent comprising an emulsion made with lamellar liquid crystals, more preferably a fatty alcohol and a surfactant emulsion. The pretreatment composition has a viscosity from 100 Pa to 300 Pa, preferably from 15 Pa to 285 Pa, more preferably from 130 Pa to 250 Pa and most preferably from 160 Pa to 240 Pa. The pretreatment composition is normally it comprises from 0.2 to 20%, preferably from 1.0 to 15% and most preferably from 5 to 15% of these conditioning agents and preferably has a pH from 3 to 7, more preferably pH 4 and pH 6.

In accordance with the present invention it has been surprisingly discovered that the application of the pretreatment composition to the hair prior to applying the coloring or decolorizing composition, preferably without a pre-rinse, provides several unexpected benefits. First, the presence of the pretreatment composition in the hair facilitates the application of the coloring or decolorizing composition since the hair does not separate too quickly or on the contrary does not become entangled when applying the composition to the hair, especially as long hair Accordingly, the compositions can be applied more quickly and effectively. Second, the pretreatment composition also prevents the hair coloring compositions from staining the skin. Third, the pretreatment compositions provide conditioning benefits that the consumer already begins to observe at the time of removing the coloring or decolorizing composition. Consequently, the pretreatment method reduces the need for a final conditioning step and thus accelerates the time the consumer needs to complete the process. Oxidative hair dye compositions are usually sold in kits comprising, in individually packaged components such as separate packages, a dye component (also referred to as "dye cream" for emulsions or "dye liquid" for solutions) comprising the dye oxidative, the precursors and the alkalizing agent which is normally ammonia in a suitable carrier and; a hydrogen peroxide component (also referred to as a "hydrogen peroxide cream" for emulsions or "hydrogen peroxide liquid" for solutions) comprising the oxidizing agent (usually hydrogen peroxide). The consumer mixes the dye component and the hydrogen peroxide component together immediately before use and applies it to the hair. The illustrated formulations provided in the following tables illustrate these resulting mixtures. Also, the bleaching compositions are also usually sold as a kit comprising two or three individually packaged components, usually in two or three separate packages. The first component comprises the ammonium ion source (eg, ammonia), the second component comprises the oxidizing agent and the third component (optional) comprises a second oxidizing agent. The bleaching compositions are obtained by mixing the aforementioned compositions immediately before use. The present invention can be used in various packaging and shipping devices. These dispatch devices can be obtained as separate devices that can be used independently or in combination with each other. The dyeing or bleaching compositions of the hair are normally contained within separate containers of one or more compartments in such a way that the compositions can be stored separately from each other before use. The compositions are then mixed by some means of mixing and applied to the consumer's hair with some means of application. The most common packaging device that can be used for the present invention comprises storing the developer in a container such as a bottle, tube, aerosol or sachet and independently storing the dye lotion in an additional compartment inside the developer container or in a container separate that may be identical, such as a double sachet or aerosol system for example, or different as a bottle and tube system. The consumer can mix the developer lotion and the dye lotion by any means. This can be done simply by using a mixing bowl in which the lotions are dispensed and then mixed, preferably using a medium of mixed as a tool. Alternatively, one of the lotions can be added in the other lotion container, (usually, the dye lotion is added to the developer lotion), and then manually stirred or mixed with a tool. Another system comprises piercing or displacing a seal located between separate compartments of the dye and developer lotion within a single container or sachet and then mixing manually within the container or in a separate and / or additional container. An example of these devices are the so-called "unscrew and use" devices. To use these devices the consumer unscrews the base of a container containing the dye and thus opens a communication port between the base of the bottle containing the dye and the upper part of the bottle containing the developer. The two components are mixed and the consumer presses the flexible upper portion of the bottle to dispense the product. Alternatively, more complex devices may be used by which the lotions are mixed at the start of the shipment. An example of such a complex system is a double aerosol system, for example, a bag inside a can or plunger. The dye and the developer are stored independently in two aerosol cans inside a device; with a propellant the contents of the can or bag are pressurized in the can or plunger and with a valve the dispatch is controlled. When the consumer activates the valve, the dye and the developer are simultaneously dispensed out of the cans and mixed by means of a static mixer just before dispensing the product on the hair. The ratio of the dye and the developer can be managed by means of the viscosity of the products, the pressure of the can or by the alteration of the size of the flow channel through the valve. In addition, the product can be a foam and be supplied in the form of modeling foam. Another example of this complex system uses a double plunger system and screw. The dye and the developer are kept in separate systems of cylindrical pistons within the system and when the consumer activates a button, two screws rotate in such a way that the double pistons that are inside pressurize the liquid in the cylinders and thereby exert force on the products so that they move through a mixing station and exit the nozzle for dispatch. The ratio of the dye and the developer can be managed by the diameter of the container cylinder. To facilitate mixing, an in-line static mixer can also be used and that system can be completely disposable or rechargeable. Another system uses one or more pumps that are activated manually. The product can be premixed in a semi-rigid sachet. When the consumer activates the pump, the liquid that is inside it is dispensed. As the manually activated pump recovers the vertical position, it exerts force so that the product leaves the semi-rigid sachet. Alternatively, the double system can be installed in such a way that two sachets and two pumps are used to supply the dye and developer lotions to the hair. Alternatively, a single pump connected to two sachets can be used to supply the product by incorporating the mixing point into the pump. Another mode uses a rigid bottle and a dip tube to connect the product to the pump system. Finally, a bottle of falling layers can be used combined with a manually activated pump, where the inner layer of the bottle is separated from the outer layer of the bottle that exerts force on the contents of the bottle for the dispatch . These complex systems usually offer the advantage of applying the product regardless of the orientation of the product. The devices described above can also be used in combination with a product supply and / or application tool to facilitate the application of this on the hair. Again, these devices can be very simple, such as a nozzle attached to one of the containers or a separate applicator device such as a comb or brush. These combs and brushes can be adapted to obtain certain effects, for example, a fast and even coverage or a retouching of the root / hairline, highlights or reflections. Alternatively, the package or one of the packages may include a comb attached to or replacing the dispensing nozzle, where the product is dispensed through hollow teeth and dispensing openings located in the teeth of the comb. The teeth of the comb can include one or multiple openings along the teeth to improve the application and uniformity of the product, especially from the root to the tip. The product can be dispensed by means of mechanical pressure applied to the container, for example, bottles with separating layers or any of the mechanisms described above. The comb can be incorporated in the container to facilitate the application and can be located vertically (called vertical comb) or at a certain angle that allows the consumer to access all areas. All the devices can be designed in such a way that they are interchangeable and in this way the consumer can be provided with several different tools to apply the composition to the hair. The application devices may also include devices that help to obtain particular effects such as streaks, for example, combs, brushes and tools for making streaks and metal sheets and hats for making streaks. To facilitate the penetration of the product into the hair, another device technology can be used. Examples of such technology include heating devices, ultraviolet light devices and ultrasound devices.

Method of use In accordance with the present invention, the method for coloring and discoloration of the hair comprises, after applying the composition to the hair and preferably impregnating the mixture for a few minutes (to ensure uniform application throughout the hair), the step of leaving the composition on the hair to that the color develops for a period of less than about 20 minutes, preferably less than about 15 minutes, more preferably about 5 minutes to about 10 minutes and most preferably about 10 minutes. After this, the consumer rinses the hair well under running water and waits for it to dry and / or comb it in the usual manner. It can be observed that instead of the original color the hair will have the desired color. According to an alternative embodiment of the present invention, the method of coloring and / or decolorizing the hair is a sequential method of oxidative discoloration or coloration comprising the steps of applying at least two treatments of oxidative discoloration or coloration of the hair in sequence, wherein the period of time between each treatment is from 1 to 60 days, preferably from 1 to 40 days, more preferably from 1 to 28 days, even more preferably from 1 to 14 days and most preferably from 1 to 7 days. In those embodiments, the time during which the composition remains in the head can be less than about 20 minutes, preferably less than 10 minutes and most preferably from about 2 minutes to about 5 minutes. According to another embodiment of the present invention, the coloring or decolorization method comprises a pretreatment step by means of which a pretreatment composition comprising at least one conditioning agent is applied to the hair and without rinsing the hair the composition is then applied coloring or decolorizing. That pretreatment composition is usually also packaged in a separate package. When present in oxidative dye compositions and bleaching compositions, the optional conditioning agent may be provided in a third container. In the latter case, the compositions can be mixed immediately before use and applied together, or the contents of the third container can be applied (after an optional rinse step) as a terminal treatment immediately after the oxidative dye composition or The resulting decolorizing composition that the mixture of the other containers. In the case of compositions comprising a radical scavenger, the scavenger may be included within the dye component, hydrogen peroxide component, pretreatment composition, if present, or may be included as a separate radical scavenger component, independently packaged . Similarly, in the case of the bleaching composition, the radical scavenger may be included within the ammonium ion source component, oxidizing agent component, second oxidizing agent component, pretreatment composition, if present, or within a separate radical scavenger component, or it may be included within two or more components. However, radical scavengers are preferably included within the dye component. The radical scavenger is usually applied to the hair during or after the application of any pretreatment composition, but before applying the coloring or decolorizing composition to the hair. Alternatively, the radical scavenger is mixed with the dye or oxidant component. In another embodiment of the present invention, the kit may comprise a separate component comprising other sensitive materials, such as certain dyes, for example, cationic azo dyes that are not stable in the dye component. principal. The kits described above are well known in the industry and the composition in each package can be manufactured using any of the standard methods, these include a) "oil in water" process, b) "phase inversion" process and c) process "one-pot" For example, in a "one-pot" process, the polymers and the chelators would previously dissolve in water to then add the fatty materials and heat the entire composition to about 70-80 ° C. Then follow a controlled cooling process and the optional mixed with shear to form the final structured product in the case of an emulsion. The addition of the materials that provide the source of peroxy monocarbonate ions, the radical scavengers and the ammonia, and optionally the solvents, dyes and pH adjusters, complete the process of making the cream dye. In the case of a liquid solution comprising acrylate polymers, these would be formulated in the hydrogen peroxide component. The glycol solvents and the fatty components are formulated in the dye component. A structured product is formed when the dye and the hydrogen peroxide components are mixed together to utilize the composition, resulting from the deprotonation of the polymeric acrylic acid groups as the pH increases, producing a polymeric microgel. U.S. Pat. no. 5,376,146 to Casperson et al. and No. 5,393,305 de Cohen et al. they contain more details on the preparation of these two-part aqueous compositions for dyeing the hair, which form a gel by mixing the two parts. The composition of the present invention can also be formulated as a 2 part aqueous composition comprising polyether polyurethane as the agent thickener (such as Aculyn® 46), as described in US Pat. num. 6,156,076 and 6,106,578.

EXAMPLES The following examples illustrate the oxidative dyeing compositions according to the present invention and the methods for the manufacture thereof.

Examples of emulsion formulations 1 -1 0 Examples of emulsion formulations 1 1 - 20 Examples of formulations of aqueous solutions thickened 1 -10 Examples of pretreatment compositions The pretreatment compositions 1-6 included below were prepared by heating the water to 80 ° C and then adding the glutamic acid and stearamidopropyldimethylamine and fatty alcohols, EDTA and benzyl alcohol and then mixing. The mixture was cooled to a temperature lower than the transition phase, additional ingredients were added and then cooled to 30 ° C. The mixture was ground using a Silverson SL2 for 3 minutes.

A rotary AR 500 rheometer (TA Instruments Ltd., Leatherhead, Surrey KT22 7UQ, UK) is used to determine the viscosity of the pretreatment compositions. The determination is made at 26.7 ° C with the steel cone measuring system unit of 4 cm 2 ° with a space of 50 μp? (micras) by means of the programmed application of a cutting speed of 0.5 to 1000 1 / s during a period of 1 minute with 10 data points registered per decade. This data is used to generate a curve of cutting speed versus shear stress for the material. The value obtained is recorded in the graphs plotted at 850 s'1. The illustrative pretreatment compositions described above can be applied to wet or dry hair (preferably dry). Immediately before use, the dye component and the oxidizing component are mixed. The resulting mixture is then applied to the hair. If the consumer has not previously dyed or is changing the color of their hair, the mixture is applied throughout the hair massaging the product in the hair from the roots to the tips (called "application over the head"). Once the application is finished, a time of 6 to 15 minutes (preferably 10 minutes) is expected for the color to develop. The product is then rinsed from the hair with hot water until no more product drips. Optionally, a product can then be applied conditioner. If the consumer is dyeing with the same color (called "root retouching"), after mixing the dye component and the oxidizing component, part of the mixture is first applied to the roots of the hair. Once the application is completed at the roots, a period of 5 to 9 minutes is expected for the color to develop. The remaining mixture is then applied to the rest of the hair and another period is expected (after finishing the application) of 1 to 10 minutes for the color to develop. Preferably, the total waiting time for the color to develop is 10 minutes or less. Once the development time is over, the product is rinsed from the hair as explained in the description of the whole head application included above. When a pretreatment composition is used, this composition is first applied to dry hair. The pretreatment composition is left on the unrinsed hair while using the "whole head application" or "root retouching" protocols described above. When the pretreatment consists of applying an effective conditioner, the consumer may omit the final separate conditioning treatment; this simplifies the procedure and reduces the total time of it.
