Technical Field

The present disclosure relates to compositions for imparting protective benefits to keratin materials, particularly hair, having components that stabilize and ameliorate the damaging effects of oxidizing agents and oxidizing agents. More specifically, the present invention relates to compositions and kits for altering hair color comprising a bleach, a developer, optionally a colorant, and an antioxidant composition, in particular an antioxidant composition comprising one or more antioxidant compounds selected from polyphenols, wherein the antioxidant composition may be combined with or with one or more components of the hair color altering composition.

Background

Methods of altering the color of hair may involve depositing onto the hair a color that provides the hair with a different shade or color, or increasing the color of the hair, such as, for example, from a dark brown shade to a medium brown or light brown shade or less, or removing the color of the hair. Permanent, semi-permanent, or temporary hair coloring products can be used to deposit hair coloring agents on hair.

Conventional hair colour altering products include colouring or colouring products comprising a colouring agent selected from oxidative precursors (oxidative dye precursors in colour formulations), commonly referred to as oxidation bases. These oxidation dye precursors are colorless or less colored compounds which, when combined with oxidative products, produce a change in hair color through an oxidative condensation process. Oxidation products conventionally use peroxides, such as hydrogen peroxide, as colour developers. Such products may also contain ammonia or other alkalizing agents, such as monoethanolamine, which causes the hair shaft to swell, allowing small oxidizing molecules to penetrate the epidermis and cortex before the oxidative condensation process is completed. In the presence of the color dye, the color complex from the oxidation reaction is trapped within the hair fiber, permanently changing the hair color. The other colorants may be selected from direct dyes, natural colorants and pigments.

Other hair color altering products include products that enhance or lighten or bleach color. Such products typically contain an oxidizing medium (oxidant) such as a persalt compound, such as a persulfate compound (as in a bleach) and/or an oxidizing agent (oxidizing agent) such as air (oxygen), an enzyme and a peroxide, for example hydrogen peroxide (as in a developer). Hair colouring or dyeing products may also enhance or lighten hair colour while depositing colour.

Unfortunately, cosmetic compositions for color enhancement and color deposition present challenges. Oxidizing agents and oxidizing media are known to cause damage to hair, which reduces the tensile strength and flexibility of the hair, making it brittle and prone to breakage. These effects in turn impart deleterious aesthetic and sensory properties including moisture loss, reduced combing, loss of natural softness, reduced elasticity, and reduced gloss. Various products include components that can coat the hair before, during, or after treatment. And other products include acids intended to neutralize strong bases in the oxidizing agent. The benefits of these products vary and often cause negative effects such as slower processing speeds, reduced color uptake or lift, and inadequate protection from injury. Thus, there remains a need for hair color-altering products and/or hair care and treatment products that provide desirable post-treatment hair quality.

The compositions and methods of the present invention may comprise, consist of, or consist essentially of the essential elements and limitations of the invention described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise available.

All percentages and ratios of components are by weight relative to the total weight of the final composition, unless otherwise specified herein.

The present inventors have surprisingly and unexpectedly found that a composition comprising a combination of at least one antioxidant compound and a color-changing system (such as an oxidative boosting or bleaching or coloring composition) imparts protection to a keratin material (such as hair) from the damaging effects of an oxidizing agent in the color-changing system when applied to the keratin material with and without heat; enhancing and protecting one or more sensory characteristics of a keratin material treated with an oxidizing agent in a color-altering system and retaining the mechanical properties and natural amino acid structure of the keratin material. Thus, the treatment composition of the present invention imparts protection to the keratinous materials from the damaging effects of oxidizing agents in order to enhance and protect one or more sensory characteristics selected from the group consisting of combability, softness, elasticity, moisture and shine. In some specific examples, the inventors have found that the use of an antioxidant composition (in particular, an antioxidant selected from baicalin, ferulic acid, pine bark extract, polydatin and ellagic acid) before or at least the application of the bleaching agent (oxidative precursor) results in a significant retention of the mechanical and sensory properties of the hair compared to treatment with the color-changing system in the absence of the antioxidant.

Without being bound by any theory, the inventors of the present disclosure believe that the antioxidant compounds in the treatment compositions of the present invention act to trap the oxidizing species (free radicals) generated in the oxidation reaction to prevent their association with the keratin fibers, thereby protecting the keratin materials from damage or minimizing damage to the hair. Thus, while other compositions employing acids may be effective in lowering pH and slowing oxidation rates, they lack the benefit of protecting the keratin fibers from damage or minimizing damage caused by excess free radicals. The compositions of the present invention provide unexpected and unexpected protective benefits not observed with comparative formulations comprising acids.

The composition according to the present invention is a composition comprising at least one or more antioxidant compounds and components of a color change system, including optionally one or more dyes or colorants. The composition may comprise other suitable ingredients for hair treatment or hair restoration. For example, in addition to antioxidant compounds, known solvents and/or additives may be used to provide additional benefits to the composition.

Antioxidant composition

The antioxidant composition according to the present disclosure is included in the composition of the present invention in various ways. The antioxidant composition comprises at least one antioxidant compound. Some representative examples of antioxidant compounds include baicalin (scutellaria root extract), pine bark extract (pine bark/bud extract), ferulic acid (hydroxycinnamic acid), and ellagic acid. Other examples include dihydrochalcones, ascorbic acid, zinc PCA and polydatin. More generally, the antioxidant compound may be selected from other phenolic compounds (including polyphenols).

Phenolic compounds

Phenolic compounds are a structural class of natural, synthetic and semi-synthetic organic compounds having one or more phenolic components. Phenolic compounds containing multiple phenolic groups are known as polyphenols. Polyphenols are commonly present in plants and are very helpful in protecting plants and animals from common health disorders and aging effects. Polyphenols act as effective radical scavengers by contributing one of their alcohol hydrogens or their delocalized electrons. Two classes of polyphenols are flavonoids and non-flavonoids.

Flavonoids are a specific group of polyphenols and the most abundant group of polyphenolic compounds, constituting two thirds of the total phenols in the amount consumed. Flavonoids are further classified by chemical structure as chalcones, flavones, flavanones, flavanols, flavonols, flavanonols, isoflavones, neoflavones, catechins, anthocyanins, and tannins. Over 4,000 flavonoids have been identified, many of which are found in fruits, vegetables and beverages (tea, coffee, beer, wine and fruit juice beverages). Flavonoids have been reported to have antiviral, antiallergic, antiplatelet, anti-inflammatory, antitumor and antioxidant activities. Flavonoids protect lipids and live cell components from damaging oxidative stress by effectively scavenging free radicals.

The non-flavonoid polyphenols include lignans, aurantione, stilbenes, curcumin and other phenylpropanoids. Many of them are also well known antioxidants like resveratrol, curcumin and pinoresinol.

In addition to polyphenols, other phenolic compounds include alkylphenols, betacyanin, capsaicin, hydroxybenzophenone, methoxyphenol, naphthoquinone, and phenolterpenes. Some common examples are ferulic acid, hydroxytyrosol, cinnamic acid, caffeic acid, and p-coumaric acid.

Selected antioxidant compounds

According to some specific examples of the present disclosure, the antioxidant compound comprises one or more of baicalin (scutellaria root extract), pine bark extract (pine bark/bud extract), ferulic acid (hydroxycinnamic acid), and ellagic acid.

The scutellaria root extract includes the compound baicalin, which is also identified as a component of the chinese herbal medicine scutellaria, a flavonoid, a class of flavonoids. It is an effective antioxidant that shows effective action against oxidative stress diseases, inflammation, allergy, cancer, bacterial infection and the like.

Pine bark extract (pine bark/bud extract) contains various compounds, including oligomeric procyanidin compounds, and is generally associated with benefits ranging from cholesterol control to other circulatory and cerebral benefits of the cardiovascular system.

Ferulic acid is a hydroxycinnamic acid that can be found widely in both the seeds of anise, coffee, apple, artichoke, peanut and citrus, and in the seeds and cell walls of plants of the commelina subclass, such as rice, wheat, oats and pineapple. Like many natural phenols, it is a strong antioxidant that reacts very strongly with free radicals and reduces oxidative stress. Many studies have shown that ferulic acid may have anti-tumour activity.

Ellagic acid is a small phytochemical that occurs naturally in red fruits and berries and in some nuts, including pomegranates, strawberries, blackberries, raspberries, bilberries, walnuts, and pecans. Ellagic acid can also be produced by decomposing ellagitannins, which can be obtained from some plants. Ellagic acid is shown to have anti-cancer activity and other benefits.

Additive agent

Optional additional antioxidant

The composition may also contain one or more additional antioxidants different from the flavonoids and ferulic acid used in the composition. The additional antioxidant may be any antioxidant suitable for use in cosmetic formulations. Suitable antioxidants include, but are not limited to, resveratrol, tannins, polyphenols, amino acids and their derivatives, imidazoles, peptides such as carnosine and derivatives, carotenoids, carotenes (such as alpha-carotene, beta-carotene, and lycopene), alpha-hydroxy acids (such as citric acid, lactic acid, or malic acid), tocopherols and derivatives (such as vitamin E), vitamin a, ascorbic acid, coenzyme Q10, bioflavonoids, glutathione, plant extracts (such as rosemary extract, olive leaf extract), and green tea extract.

The amount of additional antioxidant present in the composition may range from about 0.01% to about 20% based on the total weight of the composition; about 0.1% to about 20%; or from about 0.01% to about 10%.

Optional hydrotropes

In some embodiments, a hydrotrope or glycol may be used to increase the solubility of the components of the composition if either component is less soluble in water. The hydrotrope solution is prepared by completely dissolving one or more hydrotropes into water. One or more components are then added and mixed using a stir bar or any other mixer. Solubilization of the components occurs within minutes and mixing is continued until a clear stable solution is obtained, typically within one hour of mixing. No heating is required to dissolve the phenolic compound after this procedure. All materials were prepared at room temperature to maintain the stability of the phenolic compounds. This is extremely useful for protecting the activity of certain compounds and also making the process easier.

Hydrotropes (or hydrotropes) are a diverse class of water-soluble compounds characterized by an amphiphilic molecular structure and the ability to greatly increase the solubility of poorly water-soluble organic molecules in water. At least one hydrotrope is present in the composition in an amount effective to increase the solubility of the phenolic compound in water. By at least one hydrotrope is meant one hydrotrope or a combination of two or more hydrotropes. One or a combination of two or more hydrotropes can be used to improve the solubility of the phenolic compound in water. The amount of hydrotrope will vary depending on the type and amount of hydrotrope and phenolic compound. Increasing the water solubility of the phenolic compound refers to increasing the solubility of the phenolic compound in water as compared to the solubility of the phenolic compound in water in the absence of the one or more hydrotropes.

The advantage of using a hydrotrope is that once a stable solution is obtained, further dilution does not affect the stability of the solution. This is very different from organic solvents that are commonly used to increase the water solubility of phenolic compounds such as polyphenols. Typically, an aqueous dilution of an organic solvent with pre-dissolved one or more phenolic compounds (such as polyphenols) produces crystallization or precipitation.

Most hydrotropes have an aromatic structure with ionic moieties present, while some of them are linear alkyl chains, as listed in the table below. Although hydrotropes are clearly similar to surfactants and have the ability to reduce surface tension, their small hydrophobic units and relatively short alkyl chains distinguish them into separate classes of amphiphilic molecules. Thus, they are not hydrophobic enough to create well organized self-associated structures, such as micelles, even at high concentrations.

Common hydrophobic molecules include: sodium 1, 3-benzenedisulfonate, sodium benzoate, sodium 4-picolinate, sodium salicylate, sodium benzenesulfonate, caffeine, sodium p-toluenesulfonate, sodium butylmono-glycol sulfate, 4-aminobenzoic acid HCl, sodium isopropylbenzenesulfonate, N-diethylnicotinamide, N-picolynicotinamide, N-allylnicotinamide, 2-methacryloyloxyethylphosphorylcholine, resorcinol, butylurea, pyrogallol, N-picolylacetamide 3.5, procaine HCl, proline HCl, nicotinamide, pyridine, 3-picolylamine, sodium ibuprofen, sodium xylenesulfonate, ethyl carbamate, pyridoxal hydrochloride, sodium benzoate, 2-pyrrolidone, ethylurea, N-dimethylacetamide, N-methylacetamide, and isoniazid. Hydrotropes can be found in Lee j et al, "hydrotopic solvation of Paclitaxel: analysis of Chemical Structures for the Hydraulic Property, Pharmaceutical Research, Vol.20, No. 7, 2003; ethyl Lee s. et al, "Hydrotropic Polymers: synthesis and catalysis of Polymer containment Picolinamides Moites ", Macromolecules,36, 2248-.

Cosmetically acceptable hydrotropes refer to hydrotropes that can be used in cosmetic compositions. Although hydrotropes represent a broad class of molecules for use in various fields, cosmetic applications are limited due to safety and tolerability limitations. Suitable hydrotropes for use in cosmetics include, but are not limited to, niacinamide (vitamin B3), caffeine, sodium PCA (sodium salt of pyrrolidone carbonate), sodium salicylate, urea, and hydroxyethyl urea. The suitability of a hydrotrope for use in a cosmetic composition can be determined using tests known in the art for determining the effect on skin and toxicity to humans.

The amount of hydrotrope present in the composition can range from about 0.1% to about 20% based on the total weight of the composition; about 0.1% to about 10%; or from about 1% to about 50%.

Water (W)

The antioxidant-containing composition may contain about 1 wt% to about 99.9 wt% of water, with respect to the total weight of the composition. The amount of water in the composition may range from about 1% to 99.5% based on the total weight of the composition; about 1% to 60%; or about 1% to 50%.

pH

The pH of the composition is not limited, but is typically between 2 and 12, or between 3 and 9. The pH can be adjusted to the desired value by adding to the composition a base (organic or inorganic), for example ammonia or a primary, secondary or tertiary (poly) amine, such as monoethanolamine, diethanolamine, triethanolamine, isopropanolamine or 1, 3-propanediamine, or alternatively by adding an inorganic or organic acid, advantageously a carboxylic acid, such as for example citric acid.

Color changing system

Color changing system as defined herein refers to systems, compositions and components that can change, remove or lighten or enhance the color of hair.

Such pH adjusting agents include, but are not limited to, sodium metasilicate, silicate compounds, citric acid, ascorbic acid, and carbonate compounds. In various embodiments, the pH adjuster can be present in the bleach composition in an amount effective to provide a color-changing composition having a pH ranging from about 1 to about 7 when the bleach composition is combined with the developer.

The bleach composition may optionally contain a drying agent, such as silica. The silica may be present in the drying agent in an amount of about 1 wt% to about 3 wt%, based on the total weight of the bleach composition. As another example, a dedusting agent can also be incorporated into a bleach composition, such as when the bleach composition is in powder form and/or in the form of a cream. Exemplary dedusting agents include anhydrous and/or inert liquids such as oils, esters, alkanes, alkenes, and mixtures thereof. The dedusting agent can comprise less than about 35 wt% based on the total weight of the bleach composition, such as from about 1 wt% to about 25 wt% based on the total weight of the bleach composition.

Colouring agents or dyes

It is known practice to modify the colour of hair with lift and/or dye compositions comprising oxidative dye precursors, also commonly referred to as oxidation bases. Dye compositions comprising oxidative dye precursors are usually combined with an oxidizing agent (which may also be referred to as a developer). Oxidizing bases are colorless or weakly colored compounds which, when combined with a developer, produce colored compounds by an oxidative condensation process. It is also known that the chromaticity obtained by these oxidation bases can be varied by combining the oxidation bases with couplers or colour modifiers. The various molecules used as oxidation bases and couplers allow a wide range of colors to be obtained.

According to various embodiments, the compositions herein, in various forms, together with at least one antioxidant composition, comprise one or more hair color altering compositions or systems selected from the group consisting of: a permanent hair dye product, a semi-permanent hair dye product, a quasi-permanent hair dye product, a bleach product, a temporary dye product, or a hair lightening or highlighting product. In various embodiments, the hair color-changing composition comprises a color-changing system comprised of each of at least one bleaching agent and at least one developer. In various other embodiments, the hair color changing composition comprises a color changing system comprised of each of at least one dye or hair colorant and at least one developer. Optionally, the hair color changing composition comprising at least one dye or hair colorant comprises one or more of any of a variety of oxidative dye precursors, dye couplers, modifiers and additives.

According to some embodiments, the antioxidant composition of the present invention can be mixed with a color-changing system comprising at least one oxidizing agent or at least one oxidizing medium when it is desired to enhance the color of the hair.

According to some embodiments, the artificial color may be derived from oxidative coloration using oxidative dye precursors, or from direct coloration using direct dyes, or from oxidative coloration using a combination of oxidative dye precursors and direct dyes, or from transient coloration using transient colorants (such as pigments and natural dyes).

According to some embodiments, when carrying out oxidative colouring of hair, the antioxidant composition of the invention is combined with a colour change system comprising a colouring agent selected from oxidative dye precursors and capable of being mixed with a developer containing an oxidising agent.

Colorants may also optionally be present in the bleach composition, where such colorants useful according to various embodiments of the present disclosure are those that are stable in the bleach composition, and may impart additional toning and coloring to the hair. Exemplary hair colorants include, but are not limited to, pigments, liposoluble dyes, direct dyes, pearlescent pigments, pearling agents, leuco dyes, optically brightening colorants, natural colorants, and optically variable pigments. In at least one embodiment, the colorant present in the compositions according to the present disclosure is a non-oxidative colorant or dye.

In some embodiments, the color-changing system further comprises a colorant selected from at least one direct dye, as described above.

Furthermore, the color change system may further comprise a cosmetically acceptable carrier and/or additional adjunct ingredients, such as described above.

Typically, the dye composition containing the oxidative dye precursors may be mixed with the developer in a ratio by weight of about 1:0.01 to about 1:10, such as about 1:0.01 to about 1:0.05, about 1:0.05 to about 1:0.1, about 1:0.1 to about 1:0.5, about 1:0.5 to about 1:1, about 1:1 to about 1:2, about 1:2 to about 1:3, about 1:3 to about 1:4, about 1:4 to about 1:5, about 1:5 to about 1: 10. Thus, according to various embodiments, the dye composition containing the oxidative dye precursors may be mixed or combined with the developer at a ratio by weight of one of 1 to about 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 03, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1,2, 3, 4, 5, 6, 7, 8, 9, and 10 (including increments and ranges therebetween of about 1:0.01 to about 1: 10).

Method for changing hair color

In some embodiments, the present invention relates to changing hair color, which may be achieved when lifting or lightening or removing hair color and/or when depositing artificial color onto hair. In one embodiment, the color-changing system comprises a bleaching agent or developer.

In one embodiment, the color change system comprises a dye or colorant and a developer (which produces an artificial color on the hair).

Artificial colors can be derived from oxidative coloration using oxidative dye precursors, or from direct coloration using direct dyes, or from a combination of oxidative dye precursors and direct dyes, or from transient coloration using transient colorants (such as pigments and natural dyes).

In some embodiments, when color enhancement or hair color removal is desired, the hair treatment compositions of the present invention comprise an antioxidant composition in admixture with a developer oxidizing agent and/or a bleaching agent comprising an oxidizing medium.

In some embodiments, when performing oxidative colouring of hair, the hair treatment composition of the present invention comprises an antioxidant composition in admixture with any one of: a colorant selected from oxidative dye precursors; and a color developer containing an oxidizing agent.

The term "mixing" and all variations of this term as used herein means contacting or combining or reconstituting or dissolving or dispersing or blending or shaking the antioxidant composition with any one or more components of the color-changing system. It may also mean the incorporation of an antioxidant composition into the color-changing system. It may also mean that the antioxidant composition is placed in the same vessel or container as any one or more of the components of the color-changing system.

Thus, a method of changing the color of hair with a color change system according to the present invention comprises applying to the hair a composition for changing the color of hair comprising the antioxidant composition and the color change system of the present invention. The composition applied to the hair is formed by mixing the antioxidant composition with a color-changing system.

The antioxidant composition may be mixed or combined with the color-changing system in a ratio by weight of from about 1:0.01 to about 1:10, such as from about 1:0.01 to about 1:0.05, from about 1:0.05 to about 1:0.1, from about 1:0.1 to about 1:0.5, from about 1:0.5 to about 1:1, from about 1:1 to about 1:2, from about 1:2 to about 1:3, from about 1:3 to about 1:4, from about 1:4 to about 1:5, from about 1:5 to about 1: 10. Thus, according to various embodiments, the compositions of the invention according to the present disclosure may be mixed or combined with a color changing system in a ratio by weight of one of 1 to about 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 03, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1,2, 3, 4, 5, 6, 7, 8, 9, and 10 (including increments and ranges therebetween of about 1:0.01 to about 1: 10).

Upon application of the composition comprising the antioxidant composition and the color-changing system for changing the color of hair and resting on the hair for a period of time (dwell time), for example in the range of from about 1 to about 60 minutes, such as from about 5 to about 45 minutes, or such as from about 5 to about 20 minutes, or such as from about 10 to about 20 minutes, or such as after about 20 minutes, the hair is rinsed, optionally rinsed with a shampoo, rinsed again, optionally rinsed with a hair conditioning composition, and rinsed again, and then dried. The shampoo and hair conditioning composition can be any conventional hair shampoo and conditioner product.

In some embodiments, the antioxidant composition is applied to the keratinous substances before, simultaneously with, or after the application of the color-changing system. In some embodiments, the application is immediately before or after, and in other embodiments, the schedule between application of the formulation of the present invention and the color-changing composition may be minutes, hours, or days.

Furthermore, the mixture or composition present on the fiber or hair (resulting from the timely mixing of the antioxidant composition and the color-changing system, or the continuous application of the antioxidant composition and the color-changing system, or the application of the composition without any colorants or dyes) is left in place for a period of time, typically from about 1 to about 60 minutes, such as from about 5 to about 45 minutes, or such as from about 5 to about 30 minutes, or such as from about 5 to about 20 minutes, or such as from about 10 to about 20 minutes, or such as about 10 minutes.

The temperature during the process of changing the hair color is between room temperature and 80 ℃, and in some embodiments, between room temperature and 60 ℃.

An effective amount of the composition is typically from about 0.1 grams to about 50 grams, and in some applications for treating hair, an amount of from about 20 to 60 grams, and in yet further embodiments, for thickened hair, an amount of from about 20 to about 80 grams or more. It will therefore be appreciated that the amount applied will depend on the amount or volume of keratin material (such as hair) to be treated and may therefore fall in the lower to higher range for small or small pieces of hair and be outside this range for large or large pieces of hair. In the case of hair treatment, a typical application is for the entire head. It will be understood that application to hair generally involves passing the composition through the hair.

The hair contacted with the composition of the present invention may be air dried and/or further styled or shaped by applying heat to the hair and/or by combing or combing with the fingers or through the hair. Other shaping tools may be selected from combs and brushes.

A suitable applicator device is an applicator brush. It should be understood that while a brush is an example of a suitable applicator, particularly for hair, other applicators may be used, including but not limited to spray bottles, squeeze bottles, one and two chamber pumps, tubes, combs and other applicators known in the art.

Instructions for applying the composition of the invention to keratin fibres (such as hair) may be presented on a container (such as a can, bottle or jar) containing the composition of the invention, or on a box or case or other package comprising a container containing the composition.

The compositions described above are useful for application to keratin materials such as hair on the head of a human subject.

Thus, the compositions of the present invention can be made into various cosmetic products, such as hair care products, hair styling products, and cosmetic products.

The compositions of the present invention may be in the form of an aqueous composition or emulsion, such as an emulsion or cream.
