TECHNICAL FIELD

The present disclosure relates to compositions and methods for treating hair, kits comprising the compositions, and methods for using the compositions.

BACKGROUND

Cosmetic care compositions are frequently utilized by consumers in order to enhance, treat or change the appearance of keratinous substrates, such as hair, such as for example by changing the color, style, and/or shape of the hair, and/or by imparting various properties to hair, such as shine and conditioning. Many of the known compositions and processes for enhancing the appearance of the hair involve chemical treatment of the hair.

For example, one such chemical treatment of hair involves changing the color. This may involve removing color and/or depositing an artificial color onto the hair to provide a different shade or color, and/or to lift the color of the hair during lightening of darker hair to lighter shades. The process of lifting the color of hair, also known as lightening, generally requires the use of compositions having at least one oxidizing agent. Variation of tone height before and after the application of a hair color-altering composition is used to evaluate lightening or lifting of the color of the hair. Degree or level of lighting or lift corresponds to the variation. Notion of “tone” is based on the classification of the natural shades, one tone separating each shade from the shade immediately following or preceding it, which is well known to hairstyling professionals. Tone heights or levels range from 1 (black) to 10 (light blond), one unit corresponding to one tone. Thus, the higher the number, the lighter the shade or the greater the degree of lift. Hair lightening or color lifting compositions and hair dyeing compositions are typically alkaline, having a pH value above 7, and generally being at pH 9 and above. Presence of an alkalizing agent in amounts sufficient to make such compositions alkaline is generally required, such as ammonia or an ammonia gas generating compound and/or an amine or ammonium-based compound. Alkalizing agent causes the hair shaft to swell, thus allowing the small oxidative dye molecules to penetrate the cuticle and cortex of the hair before the oxidation condensation process is completed. Resulting larger-sized colored complexes from the oxidative reaction are then trapped inside the hair fiber, thereby permanently altering the color of the hair.

Additionally, there are many techniques and compositions for styling or altering the shape of hair. For example, hair care products referred to as “hair relaxers” or “hair straighteners” can relax or straighten curly or kinky hair, including wavy hair. Straightening or relaxing the curls of very curly hair may increase the manageability and ease of styling of such hair. Compositions for permanent waving the hair will impart a curl or a wave to otherwise straight hair. Different types of compositions can be applied onto hair in order to change its shape and make it more manageable, such as alkaline and acidic compositions. Hair relaxers, straighteners, perms, and/or waves may either be applied in a hair salon by a professional or in the home by the individual consumer.

These chemical treatments can damage the hair fibers and/or irritate the scalp while dyeing and/or lightening, relaxing, straightening, perming, and/or waving the hair. Thus, in order to reduce, or avoid, damaging the hair, as well as to improve the cosmetic performance of the compositions, the use of new, additional components and/or novel combinations of ingredients are continuously sought.

Various compositions have been provided, however, frequently the choice of components or combinations of ingredients pose difficulties insofar as they often are unstable, detrimental to other cosmetic attributes and/or present other problems. For example, many of the heretofore and utilized compositions lack ease and uniformity of application, and/or have poor rheology, viscosity, stability, color deposit and/or target shade formation. As a result, these compositions yield more disadvantages, and in many cases lead to increased damage and/or a less healthy look to the hair. It would therefore be desirable to provide the consumer with compositions and methods that can treat the hair, e.g. lift the color of hair and/or deposit color onto hair in an efficient manner, while providing other cosmetic advantages such as shine, conditioning, fiber strength, and/or a healthy appearance to the hair, but avoiding or minimizing damage to the hair.

Moreover, typically both natural and sensitized and/or chemically treated hair can contain several kinds of negatively charged moieties, for example, carboxylates (resulting from the hydrolysis of amino acids and thioester bonds) and/or sulfonates (resulting from the oxidation of disulfide bonds). These negatively charged moieties can degrade the cosmetic properties of the hair. Additionally, when hair is chemically treated or damaged, the disulfide bonds in hair (disulfide linkages between two cysteine units) can be reduced or broken, resulting in the formation of thiol groups and/or cysteic acid.

Thus, there is a need in the art for novel compositions that protect hair fibers during bleaching, thereby reducing damage or further damage to the hair. There is a further need in the art for compositions that impart cosmetic improvement and improved feel to bleached hair, such as strengthening, enhanced softness, shine, conditioning, and healthy appearance, during hair coloring, lightening, straightening, relaxing, and/or shaping.

SUMMARY

The present disclosure relates to compositions and methods for reducing damage done to hair fibers during bleaching, while also providing treatment and cosmetic improvement to hair fibers compared to traditional post-bleach feel of the hair fibers. Uniquely, the subject compositions and methods, provide stable compositions with built-in antioxidant and bonder properties that dramatically improve the quality and durability of hair during hair lightening. Damage during chemical treatment (lightening/bleaching process) is minimized and/or treated due to the use of the subject composition, which, has been found to protect the keratin fibers of the hair.

The subject compositions utilize one or more antioxidants having an aromatic ring with two alcohol functional groups, preferably baicalin, in combination with a polycarboxylic acid and an amino acid built-into a hair lightening composition to render a built-in bleach system that reduces damage to the hair. It has been surprisingly and unexpectedly found that the antioxidant with an aromatic ring with two alcohol functional groups, a polycarboxylic acid and amino acid combination is stable in a powder form when mixed with bleach powder / hair color altering agent / lightening agent, providing a built-in one-step bleaching process. Furthermore, it has been surprisingly and unexpectedly found that the combination of the one or more antioxidants having an aromatic ring with two alcohol functional groups, polycarboxylic acid and an amino acid combination provides significant benefits to fiber integrity during hair bleaching, resulting in improved tensile strength and elastic modulus, and reduced formation of citric acid, when compared to the same bleach without the required combination. Additionally, it has been found that the subject composition provides lasting smoothness and manageability to the hair after bleaching, which, on information and belief, is directly tied to the presence of the aromatic ring with two alcohol functional groups in the antioxidant synergistically operating in combination with the polycarboxylic acid and amino acid.

The invention provides, in various embodiments, compositions and kits formulated for various modes of delivery to a keratinous material to one or more of: confer protection to the keratinous material from the damaging effects of oxidants and oxidizing agents in the color altering system; enhance and protect one or more sensorial features of the keratinous material treated with oxidizing agents in the color altering system; and protect and preserve the mechanical properties and native amino acid structure of the hair.

The subject invention is directed to a built-in bleach composition with one or more selected antioxidant with an aromatic ring with two alcohol functional groups in combination with a polycarboxylic acid and an amino acid. Non-limiting benefits of the subject built-in bleach system include that the antioxidant, polycarboxylic acid and an amino acid system is stable in a powder form when mixed with bleach powder, providing a one-step bleaching process. The antioxidant, polycarboxylic acid and an amino acid combination has been found to provide benefits to fiber integrity during hair bleaching, resulting in improved tensile strength and elastic modulus, and reduced formation of citric acid, as compared to bleach compositions without the novel combination. Additionally, the subject composition has been found to provide lasting smoothness and manageability to the hair after bleaching, which on information and belief, and without being bound by theory, is directly tied to the presence of the aromatic ring with two alcohol functional groups in the antioxidant.

DETAILED DESCRIPTION OF THE DISCLOSURE

The instant disclosure relates to hair care compositions that are useful for lightening and/or coloring hair. The compositions are unique in that they reduce the amount of damage caused to the hair due to chemical processing (bleaching). A hair treatment composition relates to a composition that strengthens hair and/or reduces the damage incurred to the hair by chemical processing including the bleaching and/or coloring of the hair. Treated hair fibers (hair treated with the compositions) have desirable cosmetic properties such as improved gloss, improved combability, and improved strength and elasticity. Successful treatment of the hair can be determined by, for example, by cystic acid analysis.

It has been surprisingly and unexpectedly discovered by the inventors that compositions comprising a combination of one or more polycarboxylic acid, one or more amino acids and one or more antioxidants comprising an aromatic ring having two alcohol functional groups utilized in combination with a color altering system, such as an oxidizing lifting or bleaching or coloring composition, when applied to keratinous materials such as hair, with and without heat, confer protection to the keratinous material from the damaging effects of bleaching and/or of oxidizing agents in the color altering system; enhance and protect one or more sensorial features and preserve the mechanical properties and native amino acid structure of the keratinous material treated with bleaching and/or oxidizing agents in the color altering system. Thus, the inventive treatment compositions confer protection to the keratinous material from the damaging effects of bleaching and/or oxidizing agents to enhance and protect one or more sensorial features selected from combability, softness, elasticity, moisture and shine. In some particular examples, the inventors have discovered that using the polycarboxylic acid, amino acid and antioxidant composition on hair prior to or contemporaneously at the time of application of at least a bleach (oxidative precursor), particularly an antioxidant comprising an aromatic ring having two alcohol functional groups selected from flavonoid glycosides, preferably baicalin, and/or other polyphenols, resulted in significant retention of mechanical and sensorial properties of the hair as compared with treatments with color altering systems in the absence of an antioxidant.

Without being bound to any one theory, the inventors of the present disclosure believe that the polycarboxylic acid, amino acid and antioxidant compounds in the treatment compositions of the invention synergistically serve to capture oxidative species (free radicals) generated in the oxidation reaction to prevent their association with the keratin fibers, thereby protecting the keratinous material from damage or minimizing damage to hair. Thus, while other compositions that employ acids may effectively reduce pH and slow down the rate of oxidation, they lack the benefit of protecting the keratin fibers from damage or minimizing damage caused by excess radicals. The inventive compositions provide a surprising and unexpected protective benefit that is not observed with comparative formulations that comprise acids.

The compositions according to the invention are compositions including one or more each of polycarboxylic acids, amino acids, and antioxidant compounds, and components of a bleach and/or hair color altering system, including optionally one or more dyes or colorants. The composition may include other suitable ingredients for hair treatment or hair repair. For example, known solvents and/or additives may be utilized in addition to the polycarboxylic acids, amino acids, and antioxidant compounds to provide additional benefits to the composition.

The hair treatment compositions of the instant disclosure typically include:

(a) one or more polycarboxylic acids and/or salts thereof;

(b) one or more amino acids and/or salts thereof; and

(c) one or more antioxidants comprising an aromatic ring having two alcohol functional groups.

The amounts of the three above components (a)-(c) of the hair treatment compositions can vary and will depend on the other components (and the amounts of the other components) in the hair treatment compositions, if present. Nonetheless, in general, regardless of the other components in the hair treatment composition, the ratio of the (a) one or more polycarboxylic acids to the (b) one or more amino acids is about 2:1 to about 10:1 . Furthermore, the ratio of the (a) one or more polycarboxylic acids to the (b) one or more amino acids may be about 3:1 to about 9:1 , about 4:1 to about 8:1 , or about 5:1 to about 6:1 .

In general, the ratio of the (a) one or more polycarboxylic acids to the (c) one or more antioxidants is about 1 :1 to about 8:1 . However, the ratio of the (a) one or more polycarboxylic acids to the (c) one or more antioxidants may be about 2:1 to about 7:1 , about 2:1 to about 6:1 , about 2:1 to about 5:1 , about 3:1 to about 7:1 , about 3:1 to about 6:1 , about 3:1 to about 5:1 , or about 3:1 to about 4:1 . In general, the ratio of the (a) one or more polycarboxylic acids to the (c) one or more antioxidants is about 1 :1 to about 8:1 , if one or more cationic conditioning agents are present. However, the ratio of the (a) one or more polycarboxylic acids to the (c) one or more cationic conditioning agents may be about 2:1 to about 7:1 , about 2:1 to about 6:1 , about 2:1 to about 5:1 , about 3:1 to about 7:1 , about 3:1 to about 6:1 , about 3:1 to about 5:1 , or about 3:1 to about 4:1 .

Generally, the ratio of the (b) one or more amino acids to the (c) one or more antioxidants is about 1 :1 to about 1 :10. Furthermore, the ratio of the (b) one or more amino acids to the (c) one or more antioxidants may be about 1 :2 to about 1 :9, about 1 :4 to about 1 :8, or about 1 :5 to about 1 :6.

In general, the ratio of the (b) one or more amino acids to the (c) one or more cationic conditioning agents is 0.1 :1 to about 5:1 , if present. However, the ratio of the (b) one or more amino acids to the (c) one or more cationic conditioning agents may be about 0.1 :1 to about 2:1 , about 0.1 :1 to about 1 :1 , about 0.2:1 to about 3:1 , about 0.2:1 to about 2:1 , about 0.2:1 to about 1 :1 , about 0.5:1 to about 3:1 , about 0.5:1 to about 2:1 , or about 0.5:1 to about 1 :1 .

The instant disclosure also relates to hair lightening compositions that include the components of the hair treatment compositions mentioned above. A treatment composition can be added directly to a hair lightening composition to derive a ready- to-use hair lightening composition. For example, the hair treatment compositions can be added to a hair lightening composition, mixed, and the mixture immediately (within 1 to 60 minutes) applied to hair. Alternatively, the hair lightening composition can already include the components of the hair treatment composition (no separate packing and mixing is required). Accordingly, the instant disclosure relates to hair lightening compositions comprising:

(a) one or more polycarboxylic acids and/or salts thereof;

(b) one or more amino acids and/or salts thereof;

(c) one or more antioxidants; and

(d) one or more bleaching agents.

In some instances, the polycarboxylic acid may be selected from the group consisting of maleic acid, malonic acid, citric acid, salts thereof, or mixtures thereof.

The total amount of the one or more polycarboxylic acids, and/or salt thereof, can vary, but is typically about 0.1 to about 10 wt.%, based on the total weight of the hair lightening composition.

More exhaustive but non-limiting lists of components that are useful in the compositions of the instant disclosure are presented below.

Antioxidant Compositions

The antioxidant composition according to the disclosure are variously included in the inventive compositions. The antioxidant compositions comprise at least one antioxidant compound. Some representative examples of antioxidant compounds include baicalin (Scutellaria Baicalensis root extract), pine bark extract (Pinus Pinaster bark/bud extract), ferulic acid (a hydroxycinnamic acid) and ellagic acid. Other examples include dihydrochalone, ascorbic acid, zinc PCA, and polydatin. More generally, the antioxidant compounds may be selected from among other phenolic compounds (including polyphenols).

Phenolic Phenolic compounds are a structural class of natural, synthetic, and semisynthetic organic compounds that have one or more phenolic constituents. Phenolic compounds containing multiple phenol groups are known as polyphenols. Polyphenols are normally available in plants and are very helpful to protect plants and also animals from usual health disorders and also the impacts of aging. Polyphenols function as potent free radical scavengers by donating their alcoholic hydrogen or one of their delocalized electrons. The two classes of polyphenols are flavonoids and non-flavonoids.

Flavonoids are a specific group of polyphenols, and are the most plentiful group of polyphenol compounds, making up about two-thirds of the total phenols in consumed feed. Flavonoids are further categorized, according to chemical structure, into chaicones, flavones, flavanones, flavanols, flavonols, dihydroflavonols, isoflavonoids, neoflavonoids, catechins, anthocyanidins, and tannins. Over 4,000 flavonoids have been identified, many of which occur in fruits, vegetables and beverages (tea, coffee, beer, wine and fruit drinks). The flavonoids have been reported to have antiviral, anti-allergic, antiplatelet, anti-inflammatory, antitumor and antioxidant activities. Flavonoids protect lipids and vital cell components from damaging oxidative stress by efficiently scavenging free radicals.

Non-flavonoid polyphenols include lignans, aurones, stilbenoids, curcuminoids and other phenylpropanoids. Many of them are also well-known antioxidants like resveratrol, curcumin, and pinoresinol.

Other phenolic compounds, in addition to polyphenols, include alkylphenols, betacyanins, capsacinoids, hydroxybenzoketones, methoxyphenols, naphthoquinones, and phenolic terpenes. Some popular examples are ferulic acid, hydroxytyrosol, cinnamic acid, caffeic acid, and p-coumaric acid.

Selected Antioxidant Compounds

In accordance with some particular examples according to the disclosure, antioxidant compounds include one or more of baicalin (Scutellaria Baicalensis root extract), pine bark extract (Pinus Pinaster bark/bud extract), ferulic acid (a hydroxycinnamic acid) and ellagic acid.

Scutellaria Baicalensis root extract includes the compound baicalin, which has also been identified as a component of Chinese medicinal herb Huang-chin, is a flavone, a type of flavonoid. It is a potent antioxidant that demonstrates potent effects against oxidative stress diseases, inflammation, allergy, cancer, bacterial infections, etc.

Pine bark extract (Pinus Pinaster bark/bud extract) contains a variety of compounds, including oligomeric proanthocyanidin compounds, and is generally associated with benefits that range from cholesterol control to cardiovascular, other circulatory and brain benefits.

Ferulic acid is a hydroxycinnamic acid that can be broadly found in giant fennel, the seeds of coffee, apple, artichoke, peanut, and oranges, as well as in both seeds and cell walls of commelinid plants (such as rice, wheat, oats, and pineapple). Like many natural phenols, it is a strong antioxidant that is very reactive toward free radicals and reduces oxidative stress. Many studies suggest that ferulic acid may have antitumor activity.

Ellagic acid is a small phytochemical that occurs naturally in red fruits and berries and in some nuts, including pomegranate, strawberries, blackberries, raspberries, cranberries, walnuts and pecans. Ellagic acid can also be generated by breaking down ellagitannins that can be obtained from some plants. Ellagic acid has been shown to have anticancer activity among other benefits.

Additives

The compositions can also contain one or more additional antioxidants that is/are different from the flavonoid(s) used in the composition and ferulic acid. Additional antioxidants can be any antioxidant suitable for use in cosmetic formulations. Suitable antioxidants include, but are not limited to, resveratrol, tannic acid, polyphenols, amino acids and derivatives thereof, imidazoles, peptides such as carnosine and derivatives, carotenoids, carotenes (such as a-carotene, -carotene, and lycopene), a-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 extracts), and green tea extracts.

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

Hydrotropes or glycols may be used in some embodiments to increase solubility of the components of the compositions if solubility of any of the components in water is low. A hydrotrope solution is prepared by completely dissolving one or more hydrotropic agents into water. The component(s) are then added in and mixed using stirring bar or any other mixer. Solubilization of the components occurs within minutes, and mixing continued until clear stable solution is obtained, usually within one hour of mixing. No heat is necessary by following this procedure to dissolve phenolic compounds. Everything is prepared at room temperature to keep the stability of phenolic compounds. This is extremely useful to protect the activity of certain compounds and also makes the process much easier.

Hydrotropes (or hydrotropic agents) are a diverse class of water-soluble compounds that are characterized by an amphiphilic molecular structure and ability to dramatically increase the solubility of poorly soluble organic molecules in water. The at least one hydrotrope is present in the composition in amounts effective to increase the solubility of the phenolic compound in water. At least one hydrotrope refers to one 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 phenolic compounds in water. The amount of hydrotrope will vary depending on the hydrotrope and the type and amount of phenolic compound. Increasing the water solubility of the phenolic compound(s) refers to increasing the solubility of the phenolic compound(s) in water in comparison with solubility of the phenolic compound(s) in water in the absence of the hydrotrope or hydrotropes.

An advantage of using hydrotropes is that once a stable solution is obtained, further dilution doesn't influence 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 organic solvents with pre-dissolved phenolic compound(s), such as a polyphenol, results in crystallization or precipitation.

Most hydrotropes have aromatic structure with an ionic moiety, while some of them are linear alkyl chains, as listed in the table below. Although hydrotropes noticeably resemble surfactants and have the ability to reduce surface tension, their small hydrophobic units and relatively shorter alkyl chain distinguish them as a separate class of amphiphiles. Consequently, their hydrophobicity is not sufficient enough to create well organized self-associated structures, such as micelles, even with a high concentration.

Common hydrotropic molecules include: sodium 1 ,3-benzenedisulfonate, sodium benzoate, sodium 4-pyridinecarboxylate, sodium salicylate, sodium benzene sulfonate, caffeine, sodium p-toluene sulfonate, sodium butyl monoglycolsulfate, 4- aminobenzoic acid HCI, sodium cumene sulfonate, N,N-diethylnicotinamide, N- picolylnicotinamide, N-allylnicotinamide, 2-methacryloyloxyethyl phosphorylcholine, resorcinol, butylurea, pyrogallol, N-picolylacetamide 3.5, procaine HCI, proline HCI, nicotinamide, pyridine, 3-picolylamine, sodium ibuprofen, sodium xylenesulfonate, ethyl carbamate, pyridoxal hydrochloride, sodium benzoate, 2-pyrrolidone, ethylurea, N,N-dimethylacetamide, N-methylacetamide, and isoniazid. Hydrotropes can be found in Lee J. et al., “Hydrotropic Solubilization of Paclitaxel: Analysis of Chemical Structures for Hydrotropic Property”, Pharmaceutical Research, Vol. 20, No. 7, 2003; and Lee S. et al., “Hydrotropic Polymers: Synthesis and Characterization of Polymers Containing Picolylnicotinamide Moieties”, Macromolecules, 36, 2248-2255, 2003.

Cosmetically acceptable hydrotropes refers to hydrotropes that can be used in cosmetic compositions. While hydrotropes represent a broad class of molecules used in various fields, cosmetic applications will be limited due to safety and tolerance restrictions. Suitable hydrotropes for use in cosmetics include, but are not limited to, nicotinamide (vitamin B3), caffeine, sodium PCA (sodium salt of pyrrolidone carbonic acid), sodium salicylate, urea, and hydroxyethyl urea. The suitability of a hydrotrope for use in cosmetic compositions can be determined using tests known in the art for determining effects on skin, and toxicity to humans.

The amount of hydrotropes present in the compositions can range from about 0.1 % to about 20%; about 0.1% to about 10%; or about 1% to about 5%, based on the total weight of the composition.

Water

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

BH

The pH of the compositions is not limited but is generally between 2 and

12, or between 3 and 9. The pH can be adjusted to the desired value by addition of a base (organic or inorganic) to the composition, for example ammonia or a primary, secondary or tertiary (poly)amine, such as monoethanolamine, diethanolamine, triethanolamine, isopropanolamine or 1 ,3-propanediamine, or alternatively by addition of an inorganic or organic acid, advantageously a carboxylic acid, such as, for example, citric acid.

Polycarboxylic acids

The polycarboxylic acid may be chosen especially from linear, branched and/or cyclic, saturated or unsaturated, or even aromatic, polycarboxylic acids, containing 2 to 50, especially 2 to 40 carbon atoms, in particular 3 to 36, or even 3 to 18, 4 to 12 carbon atoms, or even 5 to 10 carbon atoms; the acid comprising at least two carboxylic groups COOH, or from 2 to 4 COOH groups; and possibly comprising 1 to 10 or 1 to 6 identical or different heteroatoms, chosen from O, N and S; and/or possibly comprising at least one perfluoro radical chosen from -CF2-- (divalent) or -CF ₃ .

In some cases, the said polycarboxylic acid is saturated, linear and aliphatic and contains 2 to 36 carbon atoms, especially 3 to 18 carbon atoms or even 4 to 12 carbon atoms; or alternatively is aromatic and contains 8 to 12 carbon atoms. In some cases, it may comprise 2 to 4 COOH groups.

The cyclic anhydride of a polycarboxylic acid may especially correspond to one of the following formulae: in which the groups A and B are, independently of each other: a hydrogen atom, a saturated or unsaturated, linear, branched and/or cyclic aliphatic, or alternatively aromatic, carbon-based radical; containing 1 to 16 carbon atoms, especially 2 to 10 carbon atoms or even 4 to 8 carbon atoms, especially methyl or ethyl, or alternatively A and B taken together form a saturated or unsaturated, or even aromatic, ring comprising in total 5 to 14, especially 5 to 10 or even 6 to 7 carbon atoms. In some cases, A and B represent a hydrogen atom or together form an aromatic ring containing in total 6 to 10 carbon atoms.

Among the polycarboxylic acids or anhydrides thereof that may be used, mention may be made, alone or as a mixture, of: dicarboxylic acids such as decanedioic acid, dodecanedioic acid, cyclopropanedicarboxylic acid, cyclohexanedicarboxylic acid, cyclobutanedicarboxylic acid, naphthalene-1 ,4- dicarboxylic acid, naphthalene-2,3-dicarboxylic acid, naphthalene-2,6-dicarboxylic acid, suberic acid, oxalic acid, malonic acid, succinic acid, phthalic acid, terephthalic acid, isophthalic acid, tetrahydrophthalic acid, hexahydrophthalic acid, pimelic acid, sebacic acid, azelaic acid, glutaric acid, adipic acid, fumaric acid, maleic acid, itaconic acid and fatty acid dimers (especially of Cse); tricarboxylic acids such as cyclohexanetricarboxylic acid, trimellitic acid, 1 ,2,3-benzenetricarboxylic acid and 1 ,3,5-benzenetricarboxylic acid, tetracarboxylic acids such as butanetetracarboxylic acid and pyromellitic acid, cyclic anhydrides of these acids and especially phthalic anhydride, trimellitic anhydride, maleic anhydride and succinic anhydride.

Amino Acids Amino acids are well known. An “amino acid” is any organic compound having both an amino group and a carboxylic acid group. In some cases, the one or more amino acids are N-acyl amino acids. The amino acid can be one of any of the amino acids known in the art. The N-acyl amino acids correspond to the formula: wherein R can be a hydrogen, alkyl (substituted or unsubstituted, branched or straight chain), or a combination of alkyl and aromatic groups. A list of possible side chains of amino acids known in the art are described in Stryer, Biochemistry, 1981 , published by W.H. Freeman and Company, which is incorporated herein by reference in its entirety. R ¹ can be C1 to C30, saturated or unsaturated, straight or branched, substituted or unsubstituted alkyls; substituted or unsubstituted aromatic groups; or mixtures thereof.

In some cases, the N-acyl amino acid compound is selected from the group consisting of N-acyl Phenylalanine, and N-acyl Tyrosine. The amino acid can be the D or L isomer or mixtures thereof. N-acyl Phenylalanine corresponds to the following formula: wherein R ¹ can be C1 to C30, saturated or unsaturated, straight or branched, substituted or unsubstituted alkyls; substituted or unsubstituted aromatic groups; or mixtures thereof. N-acyl Tyrosine corresponds to the following formula: wherein R ¹ can be C1 to C30, saturated or unsaturated, straight or branched, substituted or unsubstituted alkyls.

Table 3: Developer Formulations

The inventive and comparative formulas (per Tables 1 and 2) were mixed with the bleach composition (bleach powder) and bleach developer (either 30 or 40V) according to the weight amounts provided in Table 3.

The hair lightening compositions of Ex. A - Ex. D were mixed with a 40V developer compositions (comprising hydrogen peroxide) in a mix ratio of 1 :2 (hair lightening composition: developer composition) and used to treat hair. The hair was subsequently subjected to cysteic acid analysis, which is a measurement showing the degree of damage to the hair.

The bleach mixtures of Ex. A - Ex. D were applied to Regular Bleach Swatches, obtained from International Hair Import Products, for 50 plus minutes based on reaching equivalent lightening compared to the control. The swatches are rinsed and shampooed once before being blown dry.

Cysteic acid analysis was measure, showing the degree of damage to the hair. Extensive studies of the influence of the cysteine content on the denaturing of the a-helices in keratins have shown, for example, that the melting temperature (transition temperature) of the keratin increases linearly with the cysteine content. The increased stability of the matrix region attributable to the relatively high degree of crosslinking of the high proportion of disulfide bridges in the matrix means that transition of the helices embedded in this matrix is made difficult and, accordingly, results in an increase in the melting temperature. Conversely, a reduction in the melting point and, above all, in the enthalpy of fusion can generally be observed in chemically treated hair.

Elastic modulus (Young’s modulus) and break stress were also measured to characterize hair and the degree damage to hair. The elastic modulus represents a measure of the hair’s spring-like structure (elasticity). Higher elastic modulus shows that the hair is more elastic (less brittle). Break stress represents the force/area needed to break the hair fiber. A higher break stress represents a stronger and stiffer hair fiber.

Differential Scanning Calorimetry (DCS) is a tool that can also be useful for investigating the structural characteristics of hair fibers. Keratin undergoes detectable transformations at various temperatures. Changes in these transformation temperatures can be used to estimate how a particular hair-treatment may impact hair fibers. In the instant case, DSC was used to measure denaturation temperature (Td). Denaturation temperature (Td) has been used as a representation of the thermal stability of hair fibers, which is influenced, at least in part, by the crosslink density of the matrix (intermediate filament associated proteins, IFAP). Thermal stability (Td) and its relationship in determining the thermal stability of hair fibers is established in the literature.

Results: The system was evaluated using miniature tensile testing (MTT) to measure the impact of the bleaching on tensile strength and elastic modulus. Amino acid analysis (AAA) was performed on bleached hair fibers to measure the formation of citric acid, which indicates the amount of cysteine bonds broken. Cosmetic hair attributes were evaluated by professional stylists in comparative on- head testing. Stability was evaluated based on standard procedure. The results for the cysteic acid testing, elastic modulus, break stress, and DSC for hair treated with the hair lightening compositions for Ex. A - Ex. C demonstrated significant improvement in cysteic acid testing, elastic modulus, break stress, and DSC for hair treated with the hair lightening compositions in comparison to that treated with Ex. D. The baicalin/citric acid/glycine combination provides an instrumental benefit to fiber integrity during hair bleaching, resulting in improved tensile strength and elastic modulus, and reduced formation of citric acid, versus the same bleach without the actives. Additionally, the samples with Ex. A - Ex. C were found to provide a lasting smoothness and manageability to the hair after bleaching. The actives of Ex. A - Ex. C found stable in 45 °C chamber, finding no clumping occurred when mixed or built-in to the bleach. Ex. A - Ex. C were evaluated through MTT, AAA, and in salon testing. Compared to Ex. D, Ex. A - Ex. C were found to have a higher tensile strength, higher elastic modulus, and lower presence of cysteic acid. In salon testing, the formula Ex. A - Ex. C was found to provide smoothing and manageability attributes to the volunteers evaluated. The foregoing description illustrates and describes the disclosure.
