Description:
TECHNICAL FIELD 
     The invention is in the field of oxidatively coloring hair, specifically, an improved method that permits oxidatively coloring dark hair to a lighter color without the associated drawbacks. 
     BACKGROUND OF THE INVENTION 
     It is always difficult and challenging to oxidatively color hair to a lighter color than the base hair shade, particularly when the base hair shade is black or very dark brown. There are basically two functions taking place in an oxidative hair color process: lifting and color deposit. Lifting involves bleaching melanin from the hair. Color deposit occurs when the oxidative dyes then impart color to the bleached hair strands. In order to oxidatively color hair to at least two shades lighter than the base hair shade it is critical that both lift and color deposit be optimal. 
     There are oxidative hair color kits on the market that purport to provide high lift and color deposit in one step. For example, L&#39;Oréal Superior Preference® les True Brunettes is an oxidative hair color kit that the manufacturer states is for use in coloring dark hair to an ultra-lightening brown with no brassiness; and L&#39;Oréal Féria Hi-Lift Browns a kit that the manufacturer advertises is suitable for lightening the color of very dark hair to a lighter brown shade. However, both kits provide for a one step process, e.g. the oxidative hair color is combined with a 30 volume developer and used to color the hair. The lifting and color deposit occurs in one step. While the process is generally effective, when lifting and coloring occur in one step the degree of lift (or lightening) is often not optimal. In addition, such processes generally provide color deposit that tends to be very ashy with purple or green tones. This occurs because the manufacturers of such colorants incorporate these shades to counteract the brassiness that sometimes occurs. 
     Further, even with kits like this it is difficult to obtain a final hair color that is more than two levels over the base hair color shade. Such products are also generally not acceptable for use on gray hair since they provide a tone that tends to be green or purple. 
     Salons have procedures for oxidatively coloring hair to a lighter shade that are completed in two steps. In the first step the hair is oxidatively colored with a high lift composition to remove melanin, followed by a second oxidative color procedure where an oxidative dye and developer are combined and the mixture is used to color the hair. However, this two step procedure involves application of oxidative compositions in both steps, which in turn may produce color that is less than optimal. 
     Accordingly, there is a need to provide an oxidative hair color method and compositions for lightening dark hair that will provide lightening that is up to, or greater than 2 levels more than the base hair color shade, but without brassiness and the other drawbacks associated with the traditional one step processes. 
     It is an object of the invention to provide a method for oxidatively coloring hair to a shade more than one or two levels lighter than the base hair color shade. 
     It is a further object of the invention to provide a method for oxidatively coloring dark hair to a lighter hair color. 
     It is a further object of the invention to provide a two step high lift method for oxidatively coloring hair to achieve hair color with improved vibrancy and reduced brassiness. 
     It is a further object of the invention to provide a two step high lift hair coloring method where the color deposit is true and vibrant. 
     SUMMARY OF THE INVENTION 
     The invention is directed to a two step high lift method for oxidatively coloring hair comprising a first step of applying to the hair a color lifting mixture for a period of time sufficient to lift the hair, followed by a second step of applying an inactivated oxidative dye composition for a period of time sufficient to color the hair. 
     The term “lift” means lightening. The term “high lift” when used herein means that the method of the invention is capable of lightening hair at least one to two levels above the base hair shade, preferably at least two levels. 
     The invention is further directed to a method for improving color vibrancy and reducing brassiness of oxidatively colored hair comprising treating the hair with a two step high lift method comprising a first step of applying to the hair a hair lifting mixture for a period of time sufficient to lift the hair, followed by a second step of applying an inactivated oxidative dye composition for a period of time sufficient to color the hair.

     The method of the invention comprises the use of certain compositions according to certain procedures. 
     I. The Compositions Used in the Method 
     A. The Lifting Mixture 
     In order to achieve the lifting required in the first step of the invention process, the hair is treating with a lifting mixture. The lifting mixture is prepared immediately prior to use by combining an aqueous oxidizing agent composition and a hair lifting composition. When the two are combined the aqueous oxidizing agent composition activates the lifting composition such that the mixture is then operable to “lift” or bleach melanin from the hair fibers.

No. 6,613,311, both of which are hereby incorporated by reference in their entirety. 
     (a). Persulfates 
     The persulfate composition comprises about 15-65%, preferably about 20-60%, more preferably about 25-55% by weight of the total persulfate composition of one or more inorganic persulfates which may be alkali metal or alkaline earth metal persulfates, or ammonium persulfate. 
     (b). Alkalizing Agents 
     The persulfate composition preferably contains one or more alkalizing agents. Preferred alkalizing agents are one or more inorganic salts as set forth herein. Suggested ranges of inorganic salts are from about 0.1-40%, preferably about 0.5-35%, preferably about 1-30% by weight of the total composition. 
     (c). Particulate Fillers 
     The persulfate composition also preferably comprises one or more particulate fillers. Preferably, the persulfate composition comprises about 5-60%, preferably about 8-55%, more preferably about 10-50% by weight of the total persulfate composition of the particulate fillers. The term “particulate filler” means a generally inert particulate having a particle size of about 0.1-250 microns. The particulate fillers provide volume and, when mixed with the persulfates, dilute the persulfate particles. A variety of particulate fillers are suitable including inorganics, inorganic salts, hydrophilic colloids, carbohydrates, soaps, alkyl sulfates, and the like. 
     (i) Inorganics 
     Examples of inorganics include silica, hydrated silica, alumina, attapulgite, bentonite, calcium oxide, chalk, diamond powder, diatomaceous earth, fuller&#39;s earth, hectorite, kaolin, mica, magnesium oxide, magnesium peroxide, montmorillonite, pumice, talc, tin oxide, zeolite, zinc oxide, and the like. 
     (ii) Hydrophilic Colloids 
     Examples of suitable hydrophilic colloids include hydroxyethylcellulose, locust bean gum, maltodextrin, methylcellulose, agar, dextran, dextran sulfate, gelatin, pectin, potassium alginate, sodium carboxymethylchitin, xanthan gum, and the like. 
     (iii) Carbohydrates 
     Examples of suitable carbohydrates include sugars such as glucose, sucrose, maltose, xylose, trehelose, and derivatives thereof, in particular sugar esters of long chain, C 14-30  fatty acids, as well as dextrins, cellulosics, and derivatives thereof. 
     (iv) Soaps and Alkyl Sulfates 
     Examples of soaps and alkyl sulfate particles that may act as particulate fillers include the aluminum, sodium, and potassium salts of fatty acids such as aluminum distearate, aluminum isostearate, aluminum myristate, calcium behenate, calcium stearate, calcium behenate, magnesium stearate, magnesium tallowate, potassium palmitate, potassium stearate, potassium oleate, sodium stearate, sodium oleate, sodium myristate, sodium palmitate, and the like. Suitable alkyl sulfates include sodium lauryl sulfate, sodium cetyl sulfate, sodium myristyl sulfate, sodium octyl sulfate, and the like. 
     (d). Inorganic Colorants 
     If desired, the persulfate composition may comprise about 0.01-2%, preferably about 0.05-1%, more preferably about 0.1-1% by weight of the total persulfate composition of an inorganic colorant. The inorganic colorant is preferably in the particulate form and will provide a subtle coloration to the powder composition to make it more aesthetically pleasing for commercial purposes. Particularly preferred for use in the bleach composition is ultramarine blue. 
     B. The Inactivated Dye Composition 
     In the method of the invention, in the second step, an inactivated dye composition is applied to the hair. The term “inactivated” means that the dye composition has not been combined with an aqueous oxidizing agent composition in a pre-mix prior to application to the hair. Rather, according to the method of the invention, the hair is first treated with the lifting mixture obtained by combining the aqueous oxidizing agent and the lifting composition for the requisite period of time. Thereafter, the inactivated dye composition is applied on top of the lifting mixture already on the hair. 
     The inactivated dye composition may be in a liquid, solid, or semi-solid form. It may be in a shampoo, conditioner, or any other type of composition form. The inactivated dye composition generally contains at least one oxidative primary intermediate that is operable to color hair when in the oxidized or activated form, which occurs when the inactivated dye composition is applied to the hair on top of the developer composition. The composition generally comprises from about 0.01-35%, preferably from about 0.1-25%, more preferably from about 0.5-20% by weight of the total composition of at least one oxidative dye; and from about 0.01-95%, preferably about 0.05-95%, preferably about 0.1-85% by weight of the total composition of water. The composition may be in the form of a solution or emulsion. If the latter, the emulsion generally comprises from about 0.01-95%, preferably about 0.05-85%, more preferably about 0.1-80% by weight of the total composition of water and about 0.01-80%, preferably about 0.1-65%, preferably about 0.5-50% by weight of the total composition of an oily phase. The first composition may comprise a variety of other ingredients as further described herein. 
     1. Oxidative Dyes 
     (a). Primary Intermediates. 
     The inactivated oxidative dye composition comprises at least one primary intermediate and, optionally, at least one coupler for the formation of oxidative dyes. It is noted that the primary intermediates and optional couplers that are found in the inactivated dye composition are generally selected to impart the desired color to the hair. This is in contrast to the optional oxidative dyes that may be found in the lightening mixture, which are selected to impart maximum bleaching or lifting of the hair. 
     Suitable ranges of primary intermediates are about 0.0001-6%, preferably about 0.0005-5.5%, more preferably about 0.001-5% by weight of the total composition. Such primary intermediates are well known for use in hair color, and include ortho or para substituted aminophenols or phenylenediamines, including para-phenylenediamines of the formula: 
                                
wherein R 1  and R 2  are each independently hydrogen, C 1-6  alkyl, or C 1-6  alkyl substituted with one or more hydroxy, methoxy, methylsulphonylamino, aminocarbonyl, furfuryl, unsubstituted phenyl, or amino substituted phenyl groups; R 3 , R 4 , R 5 , and R 6  are each independently hydrogen, C 1-6  alkyl, C 1-6  alkoxy, halogen, or C 1-6  alkyl substituted with one or more hydroxy or amino groups.

     Preferred primary intermediates are p-phenylenediamine, p-aminophenol, o-aminophenol, N,N-bis(2-hydroxyethyl)-p-phenylenediamine, 2,5-diaminotoluene, their salts and mixtures thereof. 
     (b). Color Coupler 
     The inactivated oxidative dye composition may optionally comprise from about 0.0001-10%, more preferably about 0.0005-8%, most preferably about 0.001-7% by weight of the total oxidative composition of one or more color couplers. Suitable color couplers include, for example, those having the general formula:

     The inactivated oxidative dye composition may also contain a variety of other ingredients such as surfactants, conditioners, humectants, pigments, and the like. 
     2. Surfactants 
     The inactivated oxidative dye composition may comprise one or more surfactants that may assist in maintaining the composition in the emulsion form if it is an emulsion, or aid in the foaming or cleansing capability of the composition if it is in the shampoo form. Suitable surfactants include anionic surfactants, nonionic surfactants, amphoteric surfactants, and the like. If present, surfactants may range from about 0.001-50%, preferably about 0.005-45%, more preferably about 0.1-40% by weight of the first composition. 
     (a) Nonionic Surfactants 
     Suggested ranges of nonionic surfactant, if present, are about 0.01-10%, preferably about 0.05-8%, more preferably about 0.1-7% by weight of the total oxidative composition. Suitable nonionic surfactants include alkoxylated alcohols or ethers, alkoxylated carboxylic acids, sorbitan derivatives, and the like. 
     Suitable alkoxylated alcohols, or ethers, are formed by the reaction of an alcohol with an alkylene oxide, usually ethylene or propylene oxide. Preferably the alcohol is a fatty alcohol having 6 to 30 carbon atoms, and a straight or branched, saturated or unsaturated carbon chain. Examples of such ingredients include steareth 2-30, which is formed by the reaction of stearyl alcohol and ethylene oxide where the number of repeating ethylene oxide units is 2 to 30; Oleth 2-30 which is formed by the reaction of oleyl alcohol and ethylene oxide where the number of repeating ethylene oxide units is 2 to 30; Ceteareth 2-100, formed by the reaction of a mixture of cetyl and stearyl alcohol with ethylene oxide, where the number of repeating ethylene oxide units in the molecule is 2 to 100; Ceteth 1-45 which is formed by the reaction of cetyl alcohol and ethylene oxide, and the number of repeating ethylene oxide units is 1 to 45, and so on. 
     Also suitable as the nonionic surfactant are alkyoxylated carboxylic acids, which are formed by the reaction of a carboxylic acid with an alkylene oxide or with a polymeric ether. The resulting products have the general formula: 
                                
where RCO is the carboxylic ester radical, X is hydrogen or lower alkyl, and n is the number of polymerized alkoxy groups. In the case of the diesters, the two RCO— groups do not need to be identical. Preferably, R is a C 6-30  straight or branched chain, saturated or unsaturated alkyl, and n is from 1-100.
 
     Also suitable are various types of alkoxylated sorbitan and alkoxylated sorbitan derivatives. For example, alkoxylation, in particular, ethoxylation, of sorbitan provides polyalkoxylated sorbitan derivatives. Esterification of polyalkoxylated sorbitan provides sorbitan esters such as the polysorbates. Examples of such ingredients include Polysorbates 20-85, sorbitan oleate, sorbitan palmitate, sorbitan sesquiisostearate, sorbitan stearate, and so on. 
     (b) Anionic Surfactants 
     If desired the first composition may contain one or more anionic surfactants. Preferred ranges of anionic surfactant are about 0.01-25%, preferably 0.5-20%, more preferably 1-15% by weight of the total oxidative composition. Suitable anionic surfactants include alkyl and alkyl ether sulfates generally having the formula ROSO 3 M and RO(C 2 H 4 O) x SO 3 M wherein R is alkyl or alkenyl of from about 10 to 20 carbon atoms, x is 1 to about 10 and M is a water soluble cation such as ammonium, sodium, potassium, or triethanolamine cation. 
     Another type of anionic surfactant which may be used in the compositions of the invention are water soluble salts of organic, sulfuric acid reaction products of the general formula:
 
R 1 —SO 3 -M
 
wherein R 1  is chosen from the group consisting of a straight or branched chain, saturated aliphatic hydrocarbon radical having from about 8 to about 24 carbon atoms, preferably 12 to about 18 carbon atoms; and M is a cation. Examples of such anionic surfactants are salts of organic sulfuric acid reaction products of hydrocarbons such as n-paraffins having 8 to 24 carbon atoms, and a sulfonating agent, such as sulfur trioxide.
 
     Also suitable as anionic surfactants are reaction products of fatty acids esterified with isethionic acid and neutralized with sodium hydroxide, or fatty acids reacts with alkanolamines or ammonium hydroxides. The fatty acids may be derived from coconut oil, for example. Examples of fatty acids also include lauric acid, stearic acid, oleic acid, palmitic acid, and so on. 
     In addition, succinates and succinimates are suitable anionic surfactants. This class includes compounds such as disodium N-octadecylsulfosuccinate; tetrasodium N-(1,2-dicarboxyethyl)-N-octadecylsulfosuccinate; and esters of sodium sulfosuccinic acid e.g. the dihexyl ester of sodium sulfosuccinic acid, the dioctyl ester of sodium sulfosuccinic acid, and the like. 
     Other suitable anionic surfactants include olefin sulfonates having about 12 to 24 carbon atoms. The term “olefin sulfonate” means a compound that can be produced by sulfonation of an alpha olefin by means of uncomplexed sulfur trioxide, followed by neutralization of the acid reaction mixture in conditions such that any sultones, which have been formed in the reaction are hydrolyzed to give the corresponding hydroxy-alkanesulfonates.

     3. Polar Solvents 
     The inactivated oxidative dye composition may also comprise a variety of polar solvents other than water, including mono-, di-, or polyhydric alcohols, and similar water soluble ingredients. If present, such polar solvents may range from about 0.01-25%, preferably about 0.05-15%, more preferably about 0.1-10% by weight of the first composition of polar solvent. Examples of suitable monohydric alcohols include ethanol, isopropanol, benzyl alcohol, butanol, pentanol, ethoxyethanol, and the like. Examples of dihydric, or polyhydric alcohols, as well as sugars and other types of humectants that may be used include glucose, fructose, mannose, mannitol, malitol, lactitol, inositol, and the like. Suitable glycols include propylene glycol, butylene glycol, ethylene glycol, polyethylene glycols having from 4 to 250 repeating ethylene glycol units, ethoxydiglycol, and the like. Many of these types of alcohols also serve also serve as penetration enhancers, meaning that they enhance penetration of primary intermediates and couplers into the hair shaft by virtue of their tendency to act as humectants and swell the hair shaft. Ethoxydiglycol is a particularly good penetration enhancer and is the preferred polar solvent. 
     In the preferred embodiment of the invention the composition comprises water in addition to one or more polar solvents, which are dihydric alcohols. In the preferred compositions, about 0.001-20%, preferably about 0.005-10%, more preferably about 0.001-8% by weight of the total composition comprises a non-aqueous polar solvent.

     The inactivated oxidative dye composition may also contain one or more preservatives. Suggested ranges are about 0.0001-8%, preferably 0.0005-7%, more preferably about 0.001-5% by weight of the total composition. Suitable preservatives include methyl, ethyl, and propyl paraben, hydantoins, and the like. 
     In the preferred method of the invention the inactivated oxidative dye composition is in the form of a liquid such as a shampoo or conditioner composition. 
     II. The Method 
     A. The First Step 
     The method for coloring hair is in two steps. In the first step the hair is treated with the lifting mixture, which is prepared by combining the aqueous oxidizing agent and the lifting composition. In the case where the lifting composition in the lifting mixture comprises a persulfate bleach composition, from about 1 to 2 parts, preferably about 1.5 parts, aqueous oxidizing agent composition are combined with 0.5 to 2 parts, preferably about 1.0 parts persulfate bleach composition. In the case where the lifting mixture is an alkalizing composition, from about 1 to 2 parts aqueous oxidizing agent composition and about 0.5 to 2 parts alkalizing composition are combined to form the lifting mixture which is then applied to the hair. The proportions mentioned may vary depending on the type of hair, the hair length, and the desired properties. 
     The lifting mixture is applied to the hair strands ensuring that all hair strands are coated. The lifting mixture is left on the hair for a period of time necessary to achieve adequate lifting. In general, this period of time is from about 10-45 minutes, preferably from about 15-35 minutes, more preferably about 20 minutes. Thereafter, preferably, additional lifting mixture is added to the root area of the hair and the composition is left for an additional period of time ranging from about 5 to 15 minutes, preferably about 10 minutes. 
     Then, the inactivated oxidative dye composition is applied to the hair on top of the lifting mixture and massaged into the hair for a period of time ranging from about 1 to 15, preferably from about 1 to 8, most preferably about 2 minutes. 
     The mixture is rinsed well from the hair with water. If desired the hair may be treated with standard shampoo and conditioner. 
     Hair colored according to the two step method of the invention exhibits improved vibrancy and color tone. In addition, dark hair can be lightened more than one or two levels above the base hair shade. In general, the method of the invention permits oxidative coloring of the hair where the hair is lightened from one to five, preferably from two to four levels above the base hair color shade. 
     III. Kits 
     The compositions necessary to practice the method of the invention may be present in kit form, such as retail kits. Such kits generally contain a carton or box for holding the various kit components. The kit will contain one receptacle containing an aqueous oxidizing agent composition, a second receptacle containing the lifting composition, and a third receptacle containing the inactivated dye composition. If desired, the kit may contain other ingredients such as printed documents (like instructions, discount coupons, etc.), gloves, and so on. 
     The invention will be further described in connection with the following examples which are set forth for the purposes of illustration only.

     EXAMPLE 4 
     Split head tests were conducted on a salon panelist having dark brown hair having from about 10 to 70 gray hairs on her whole head. The developer composition of Example 1, 1.5 parts, and the alkalizing composition A from Example 2, 1 part, were combined to form a lifting mixture which was applied to strands of hair on the left side of the head, generally avoiding the root area for 20 minutes. Additional lifting mixture was then applied to the root area for an additional 10 minutes. An inactivated oxidative dye composition having the following formula was applied on the left side over the lifting mixture for 2 minutes.

     The other half head was treated according to package instructions. The bottle of Shimmering Colour Permanent Haircolour Gel was poured into the Shimmering Colour Developing Crème and mixed well. The majority of the composition was immediately applied to unwashed dry hair for 20 minutes, covering only the ends of the hair and avoiding the roots. The remaining portion of the composition was then applied to the hair roots for 10 minutes. After 30 minutes the mixture was rinsed from the hair with lukewarm water until the rinse water was clear. The Colour Hydrator No Build-Up Deep Conditioner was applied to hair for two minutes, then rinsed out with water. 
     A trained salon evaluator evaluated the results on both sides. The color tone, evenness of color, lift, and color vibrancy in the hair treated with the method of the invention was better than these same properties on the half head treated with the L&#39;Oréal product. 
     EXAMPLE 5 
     A salon panelist having dark brown hair with about 10 to 70 gray hairs on the entire head was recruited for this study. A split head test was conducted. The left side of the head was treated with a lifting mixture obtained by combining about 1.5 parts of the developer composition of Example 1 and about 1 part of alkalizing composition A from Example 2. The developer composition was applied to the hair strands, avoiding the root area, and left for 20 minutes. Additional lifting mixture was then applied to the root area for 11 minutes. The inactivated oxidative dye composition as set forth in Example 2 was applied for 2 minutes. The mixture was rinsed from the hair with lukewarm water until the water ran clear. Hair conditioner as set forth in Example 4 was applied to the hair for 2 minutes, then rinsed out with water. 
     The other half head was treated with L&#39;Oréal New Ultra-Lightening for Dark Hair Only Superior Preference® les True Brunettes, Level 3 permanent hair color UL53 (ultra light beige brown) following the package instructions.
