TITLE

COMPOSITIONS AND METHODS FOR RESTRUCTURING CHEMICALLY

TREATED HAIR

FIELD OF THE DISCLOSURE

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

BACKGROUND

Many consumers desire to use cosmetic and care compositions that enhance the appearance of keratinous substrates such as hair, e.g., by changing the color, style, and/or shape of the hair, and/or by imparting various cosmetic properties to hair, such as shine and conditioning. Many of the known compositions and processes for enhancing the appearance of hair involve chemical treatments to the hair.

The process of changing the color of hair, for example, can involve depositing an artificial color onto the hair which provides a different shade or color to the hair, and/or lifting the color of the hair, such as lightening the color of dark hair to lighter shades. The process of lifting the color of hair, also known as lightening (or bleaching), generally requires the use of oxidizing agents. Lightening of hair is typically evaluated by the variation in tone height before and after the application of a hair color-altering composition onto hair. This variation corresponds to the degree or level of lightening or lift. The 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. The tone heights or levels can 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.

In general, hair lightening or color lifting compositions and hair coloring or dyeing compositions possess an alkalinity such that these compositions have a pH value of above 7, typically being at pH 9 and above, and may generally require the presence of an alkalizing agent such as ammonia or an ammonia gas generating compound and/or an amine or ammonium-based compound in amounts sufficient to make such compositions alkaline. The alkalizing agent causes the hair shaft to swell, thus allowing the small oxidative dye molecules to penetrate the cuticle and cortex before the oxidation condensation process is completed. The 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.

While dyeing or color lifting compositions can effectively alter the color of hair, and relaxing, straightening, perming, and waving compositions can effective alter the shape of the hair, these chemical treatments can damage the hair fibers and/or irritate the scalp. Thus, in order to reduce or avoid damage to hair, as well as to improve the cosmetic performance of the compositions, the use of new and additional components and novel combinations of ingredients are continuously sought.

However, the choice of components or combinations of ingredients could pose difficulties insofar as they cannot be detrimental to other cosmetic attributes such as ease and uniformity of application, rheology or viscosity properties and stability of the compositions, color deposit and target shade formation, and/or result into more disadvantages such as increased damage or a less healthy look to the hair. It would therefore be desirable to provide the consumer with compositions and methods that can chemically treat the hair 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.

Further, both natural and sensitized 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. Moreover, 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, one objective of the disclosure is to provide novel compositions that can provide advantageous effects such as strengthening of the hair fiber, protecting hair fibers from damage or further damage, enhanced properties such as softness, shine, conditioning, healthy appearance, while at the same time, providing desired effects such as coloring, lightening, straightening, relaxing, and/or shaping.

SUMMARY OF THE DISCLOSURE

The present disclosure relates to compositions and methods for treating hair, in particular human hair of the head. The compositions and methods are unique because they dramatically improve the quality and durability of chemically treated hair. Damage during chemical treatment is repaired, minimized, and/or

compensated for due to a unique combination of components in the compositions that restructure, strengthen, or protect the keratin fibers of the hair. Hair treated with the compositions is surprisingly strengthened and the hair's cosmetic properties (e.g., softness, smoothness, and discipline) are considerably improved.

The unique combination of components that function to restructure the hair can be combined in an individual restructuring composition and applied to the hair before, after, or during a chemical treatment; or the unique combination of components can be included with the composition that chemically treats the hair (e.g., in a composition that further includes one or more active agent for chemically treating hair).

In one aspect, the instant disclosure relates to restructuring compositions that include: (a) one or more non-polymeric, mono-, di-, and/or tri-carboxylic acids; (b) one or more amines; and (c) one or more polymeric acid compounds and/or polymeric acid anhydride compounds.

The hair restructuring compositions are applied to the hair in methods for restructuring the hair. Typically, the restructuring compositions are applied to the hair within about 24 hours before or after chemically treating the hair. The hair restructuring compositions may also be applied to the hair simultaneously with a chemical treatment or added directly to a chemical treatment composition and applied as part of the chemical treatment composition. Non-limiting examples of chemical treatments include lightening, coloring, perming, and straightening of the hair. The methods do not require the use of heat. Accordingly, the methods may be carried out at room temperature (about 20°C to about 30°C) or at a temperature of about 10°C to about 50°C.

As mentioned above, the hair structuring compositions can be added and mixed with a chemical treatment composition immediately before application to hair. In some cases, however, components of the hair structuring compositions can already be part of a composition for chemically treating hair, i.e., the unique components of the hair restructuring compositions ("restructuring components") can be formulated as part of a composition for chemically treating hair. This eliminates the step of separately applying a restructuring composition to the hair and/or eliminates the need for adding the hair restructuring composition to a chemical treatment composition before use. It also avoids the need for packing the

restructuring composition separately from the chemical treatment composition.

The compositions for chemically treating hair typically include: (a) one or more non-polymeric, mono-, di-, and/or tri-carboxylic acids; (b) one or more amines; (c) one or more polymeric acid compounds and/or polymeric acid anhydride

compounds; and (d) one or more active agents. The active agents are typical the compounds responsible, at least in part, for the chemically active nature of the compositions. Active agents include, for example, oxidizing agents, reducing agents, non-reducing agents for shaping hair, dyeing agents, and mixtures thereof.

Accordingly, depending on the nature of the active agent(s), the composition for chemically treating the hair may be a hair lightening or bleaching composition, a hair coloring composition, a hair curling (perming) composition, a hair straightening composition, an anti-frizz composition, a hair smoothing composition, a hair conditioning composition, etc.

The compositions for chemically treating hair (the compositions already including the restructuring components) may be stand-alone compositions or may be used with or added to other compositions. For example, if the composition for chemically treating hair is a bleaching composition, it may be combined with a developer composition immediately before use. It is noted that either or both of the hair bleaching composition and the developer composition could include the hair restructuring components. Likewise, hair perming and hair straightening often requires more than one composition (e.g., relaxing compositions, activator compositions, neutralizer compositions, etc.). The restructuring components can be included in one or more (or all) of the various compositions.

The instant disclosure also relates to methods for chemically treating hair. The compositions of the instant disclosure are applied to the hair and allowed to remain on the hair for a period of time sufficient to achieve a desired result.

Typically, a composition is allowed to remain on the hair for about 1 min. to about 45 min. and then the composition is rinsed from the hair. The methods do not require the use of heat. Accordingly, the methods may be carried out at room temperature (about 20°C to about 30°C) or at a temperature of about 10°C to about 50°C.

The instant disclosure relates to kits, which include one or more compositions described herein. For instance, in some cases, the kits include: (i) a restructuring composition as described above; (ii) a composition comprising one or more active agents for chemically treating hair; and (iii) optionally, a composition comprising one or more hair conditioning agents; wherein each of the compositions is maintained separately in the kit. The instant disclosure also relates to kits in instances where the restructuring components are already included in one or more compositions for chemically treating hair. For example, these kits may include: (i) a composition for chemically treating hair, as described above; (ii) a composition comprising one or more second active agents that may be different than the one or more active agents in (i); and (iii) optionally, a composition comprising one or more hair conditioning agents.

Finally, as referenced previously, the instant disclosure relates to methods of using the compositions to treat hair or to restructure hair. These methods include applying one or more compositions of the instant disclosure to the hair. The one more composition may be temporarily applied to the hair (e.g., applied for a period of about 1 hour or less), or may be allowed to remain on the hair for an indefinite amount of time. When the hair restructuring components are included with a composition for chemically treating the hair, the composition for chemically treating the hair is typically applied to the hair for an amount of time sufficient to carry out the desired chemical treatment (e.g., less than about 1 hour). The compositions for chemically treating the hair are then usually rinsed from the hair after the desired amount of chemical treatment has been achieved.

DETAILED DESCRIPTION OF THE DISCLOSURE

The instant disclosure relates to restructuring hair, in particular human hair of the head. In the context of the instant disclosure, the term "restructuring" relates to strengthening hair and minimizing and/or compensating for the damage caused to hair during chemical processing. Thus, a "restructuring composition" relates to a composition that strengthens hair by minimizing and/or compensating for the damage caused to the hair during chemical processing. Restructured hair fibers (hair treated with the restructuring compositions) exhibit desirable cosmetic properties such as smoothness, gloss, improved combability, and improved strength and elasticity.

For instance, the polyamine may be an alkoxylated polyamine having at least two amino groups and at least one degree of alkoxylation. The alkoxylation is provided by an alkylene oxide group such as, for example, ethylene oxide and/or propylene oxide. In some cases, the compositions do not include polymers having dimethylamino moieties, i.e., the compositions are free of essentially free of polyamines that are polymers having dimethylamino moieties.

In some instances, the compositions of the instant disclosure are free or essentially free of VP/DMAPA acrylates copolymer. VP/DMAPA acrylates copolymer is a copolymer of vinylpyrrolidone anddimethylaminopropylacrylamide or

In some cases, the one or more polymeric acid compounds and/or polymeric acid anhydride compounds are ethylene-a,p-dicarboxylic acids, anhydrides, salts, or derivatives thereof. Suitable α,β-unsaturated carboxylic acids for copolymerization with ethylene are α,β-unsaturated aliphatic mono- or di-carboxylic acids having 3 to 8 or 3 to 5 carbon atoms. Non-limiting examples include acrylic acid, methacrylic acid, a-ethylmethacrylic acid, maleic acid, fumaric acid, and itaconic acid anhydrides, salts, or derivatives thereof. In some instances in particular, maleic acid, anhydrides, salts, or derivatives thereof are appropriate.

For example, in some cases the total amount is about 0.01 to about 25 wt.%, based on the total weight of the composition. However, the total amount of the one or more polymeric acid compounds and/or polymeric acid anhydride compounds may be about 0.01 to about 20 wt.%, about 0.01 to about 1 5 wt.%, about 0.01 to about 10 wt.%, about 0.01 to about 8 wt.%, 0.01 to about 5 wt.%, about 0.01 to about 4 wt.%, about 0.01 to about 3 wt.%, about 0.1 to about 1 0 wt.%, about 0.1 to about 8 wt.%, about 01 to about 5 wt.%, about 0.1 to about 4 wt.%, or about 0.1 to about 3 wt.%. The components of the hair structuring compositions may already be part of a composition for chemically treating hair. The unique components of the hair restructuring compositions are formulated as part of a composition for chemically treating hair. Thus, the instant disclosure relates to compositions for chemically treating hair that typically include:

(a) one or more non-polymeric, mono-, di-, and/or tri-carboxylic acids;

(b) one or more amines; and

(c) one or more polymeric acid compounds and/or polymeric acid

anhydride compounds; and

(d) one or more active agents.

An "active agent," in the context of the instant disclosure, relates to a compound, molecule, or combination of compounds/molecules that chemically changes hair. For example, an active agent may reduce disulfide bonds, reestablish or form disulfide bonds, remove melanin from the hair, covalently bond to the hair, etc. Non-limiting examples of active agents include oxidizing agents, reducing agents, non-reducing agents for shaping hair, dyeing agents, and mixtures thereof. Based on the type of active agent, the composition for chemically treating hair may be a hair lightening or bleaching composition, hair coloring composition, a hair perming or straightening composition, or a mixture thereof.

Hair lightening compositions typically include one or more oxidizing agents.

Non-limiting examples of oxidizing agents include peroxides, persulfates, perborates, percarbonates, and mixtures thereof. In some cases, the hair lightening composition includes one or more persulfates, such as those selected from the group consisting of sodium persulfate, potassium persulfate, ammonium persulfate, and mixtures thereof. In some cases, the hair lightening compositions include peroxide, such as hydrogen peroxide.

Hair perming or straightening compositions typically include one or more reducing agents. Non-limiting examples of reducing agents include cysteine or a derivative of cysteine, cysteamine or a derivative of cysteamine, thiolactic acid or an ester of thiolactic acid, thioglycolic acid or an ester of thioglycolic acid, thioglycerol, and mixtures thereof. In some cases, the reducing agent is a glyceryl or glycol monothioglycolate, diammonium dithiodiglycolate, ammonium thioglycolate, or a mixture thereof.

For example, in some cases the second oxidizing agent is a persulfate. Non-limiting examples of persulfates include potassium persulfate, sodium persulfate, ammonium persulfate, and mixtures thereof.

Hair coloring or dyeing compositions typically include one or more colorants or dyeing agents. Non-limiting examples of colorants or dyeing agents include direct dyes, oxidative dyes, direct action dyes, natural dyes, metallic dyes, reactive dyes, and mixtures thereof.

The compositions for chemically treating hair can include varying amounts of components depending on the purpose of the composition and depending on whether the composition will be combined with additional compositions. Typically, when the restructuring components are already included in a composition with the one or more active agents, the total amount of each of the restructuring agents will be less than for a restructuring composition that includes primarily the restructuring agents. The total amount of each of the restructuring components will be reduced relative to the total weight of the composition due to the addition of the one or more active agents and the additional components included in the composition for chemically treating hair.

With respect to the total amount of the non-polymeric, mono-, di-, and/or tricarboxylic acids, the composition may include about 0.01 to about 25 wt.%, about 0.01 to about 20 wt.%, 0.01 to about 15 wt.%, about 0.01 to about 10 wt.%, about 0.01 to about 5 wt.%, about 0.01 to about 4 wt.%, about 0.01 to about 3 wt.%, about 0.1 to about 20 wt.%, about 0.01 to about 1 5 wt.%, about 0.1 to about 10 wt.%, about 0.1 to about 5 wt.%, about 0.1 to about 4 wt.%, about 0.1 to about 3 wt.%, about 0.5 to about 4 wt.%, about 0.5 to about 3 wt.%, or about 1 to about 3 wt.%.

With respect to the total amount of the one or more amines, the composition may include about 0.01 to about 25 wt.%, about 0.01 to about 20 wt.%, about 0.01 to about 15 wt.%, 0.01 to about 10 wt.%, about 0.01 to about 8 wt.%, about 0.01 to about 4 wt.%, 0.01 to about 3 wt.%, about 0.01 to about 2 wt.%, about 0.05 to about 20 wt.%, about 0.05 to about 15 wt.%, about 0.05 to about 10 wt.%, about 0.05 to about 8 wt.%, about 0.05 to about 4 wt.%, about 0.05 to about 3 wt.%, 0.1 to about 15 wt.%, 0.01 to about 1 0 wt.%, 0.1 to about 5 wt%, about 0.01 to about 2 wt.%, or about 0.1 to about 2 wt.%.

With respect to the total amount of the one or more one or more polymeric acid compounds and/or polymeric acid anhydride compounds, the compositions may include about 0.01 to about 5 wt.%, about 0.01 to about 3 wt.%, about 0.01 to about 2 wt.%, about 0.01 to about 1 wt.%, about 0.01 to about 5 wt.%, about 0.01 to about 3 wt.%, about 0.01 to about 2 wt.%, about 0.1 to about 5 wt.%, about 0.1 to about 4 wt.%, about 0.1 to about 3 wt.%, about 0.1 to about 2 wt.%, or about 0.1 to about 1 wt.%.

With respect to the total amount of the one or more active agents, the composition may include about 0.01 to about 85 wt.%, about 0.01 to about 50 wt.%, about 0.01 to about 25 wt.%, about 0.01 to about 20 wt.%, about 0.01 to about 10 wt.%, about 0.01 to about 5 wt.%, about 1 to about 85 wt.%, about 1 to about 70 wt.%, about 1 to about 60 wt.%, about 1 to about 50 wt.%, about 1 to about 25 wt.%, or about 1 to about 10 wt.%, about 25 to about 95 wt.%, about 40 wt.% to about 95 wt.%, or about 50 wt.% to about 80 wt.%.

The instant disclosure further relates to methods for treating and/or restructuring hair using the restructuring compositions and the compositions for chemically treating hair. For instance, the instant disclosure relates to methods for restructuring hair, the methods comprising applying a hair restructuring composition to the hair. The hair restructuring composition may be temporarily applied to the hair for a sufficient amount of time to restructure the hair and then removed, for example, by rinsing. Alternatively, the restructuring composition may be a "leave-in" composition that does not require removal from the hair.

The methods are unique because they do not require heat to attain the dramatic improvements in cosmetic and/or sensorial properties (e.g., softness, smoothness, discipline, conditioning, etc.). Thus, the methods are typically carried out at room temperature (about 20°C to about 30°C). In particular, methods can be performed without allowing the hair and the compositions applied to the hair to reach a temperate above about 50 °C or about 60°C. The methods can be performed without applying heat during treatment or after treatment. Accordingly, the methods may be carried out at a temperature of about 10°C to about 60°C, about 15°C to about 50°C, about 15°C to about 40°C, or about 15°C to about 30°C.

The restructuring composition may be applied to the hair within about 1 hour, about 45 min., about 30 min., about 20 min., about 15 min., about 1 0 min., or about 5 min. of chemically treating the hair (before or after the chemical treatment). For example, the restructuring composition may be applied to the hair followed by application of a chemical treatment composition. Alternatively, a chemical treatment composition may be applied to the hair followed by application of a restructuring composition. In some cases, a restructuring composition is applied both before and after a chemical treatment composition is applied to the hair. In some cases, when applying a restructuring composition to the hair after chemical treatment, the chemical treatment composition is first rinsed from the hair before application of the restructuring composition. The hair restructuring composition can be applied to the hair and allowed to dry on the hair, naturally or with the use of heat and/or air (blow dry). Without rinsing the restructuring composition from the hair, a chemical treatment composition can subsequently be applied to the hair. In some cases, a restructuring composition is applied to the hair within about 1 hour, about 45 min., about 30 min., about 20 min., about 15 min., about 10 min., or about 5 min. before application of a chemical treatment composition. Likewise, in some cases, a restructuring composition is applied to the hair within about 1 hour, about 45 min., about 30 min., about 20 min., about 15 min., about 10 min., or about 5 min. after application of a chemical treatment composition. In some cases, the restructuring composition is applied simultaneously with a hair treatment composition or is added directly to the hair treatment composition before application to the hair.

If the hair treatment composition is for lightening hair, a method for lightening hair can include: (i) mixing a hair restructuring composition with a bleaching composition, and optionally with a composition comprising one or more hair conditioning agents and/or one or more direct dyes; (ii) applying the mixture onto hair and allowing the mixture to remain on the hair for about 1 to about 45 minutes; and (iii) rinsing the mixture from hair. If the hair treatment composition is for perming or straightening the hair, a method for perming and/or straightening the hair may include: (i) mixing a restructuring composition with a reducing compositions and/or with a neutralizing composition; and (ii) applying the reducing composition and/or the neutralizing composition to the hair for about 1 to about 45 minutes. Usually, the reducing composition and the neutralizing composition are applied sequentially.

The instant disclosure also relates to methods for chemically treating using chemical compositions already formulated to include the restructuring agents of the restructuring compositions. Typically, the compositions for chemically treating hair are applied to the hair for a sufficient amount of time to attain a desired result, and then rinsed from the hair. The compositions for chemically treating hair may be applied to the hair for about 1 hour, about 45 min, about 30 min, about 20 min, about 15 min, about 10 min, or about 5 min., and then rinsed from the hair. For example, if the composition for chemically treating hair is a hair lightening composition, a method for lightening the hair may include: (i) mixing a hair lightening composition with a developer composition comprising a peroxide, and optionally with a

composition comprising one or more hair conditioning agents and/or one or more direct dyes; (ii) applying the mixture onto hair and allowing the mixture to remain on the hair for about 1 to about 45 minutes; and (iii) rinsing the mixture from hair. In some cases, however, the restructuring components may be formulated with the developer composition comprising a peroxide, such that the developer composition instead of with the hair lightening composition. In some cases, the restructuring components may be included in both the hair lightening composition and the developer composition.

The compositions described in the instant disclosure may be included in kits for treating hair. Kits typically include more than one composition and therefore more than one container (or more than one compartment in a given container) to ensure that various compositions do not come into contact with each other until desired. For example, the kits may include a restructuring composition, as described previously, or may include a composition for chemically treating hair (compositions already formulated to include the restructuring agents of the restructuring

compositions). The kits may further include a developer bottle, gloves, shampoo, conditioner, and/or an odor eliminator. Instructions for use of the kit are also typically provided.

In some cases, the kits include: (i) a restructuring composition; (ii) a composition comprising one or more active agents for chemically treating hair; and (iii) optionally, a composition comprising one or more hair conditioning agents. In some cases, the kit further includes a second composition comprising one or more active agents (typically active agents that are different than in the composition of (ii)). For example, the composition of (ii) may include, as an active agent, one or more oxidizing agents selected from the group consisting of persulfates, perborates percarbonates, alkali metal bromates, ferricyanides, peroxygenated salts, and mixtures thereof. The second composition may be, for example, a developer composition that includes peroxide. Likewise, the composition of (ii) may include, as an active agent, one or more reducing agents for perming or straightening the hair and the second composition may be a neutralizing composition wherein the one or more active agents are reducing agents.

In instances where the restructuring components of the restructuring compositions are already formulated into a composition for chemically treating hair, the kits will typically include: (i) a composition for chemically treating hair; and (ii) optionally, a composition comprising one or more hair conditioning agents. Such kits may also include a composition comprising one or more second active agents (typically different than the active agents already in (i)). For example, if the composition for chemically treating hair is a hair lightening composition, the kit may include a developer composition. The restructuring agents may be included in either the hair lightening composition or the developer composition, or both. If the composition is for perming or straightening hair, the restructuring agents may be included in the reducing composition or in the neutralizing composition, or both.

Preservatives, conditioning agents including cationic conditioning agents, colorants or dyes, thickeners, surfactants including ionic surfactants, nonionic surfactants, amphoteric surfactants and/or zwitterionic surfactants, stabilizers, pH modifiers, buffers, etc., may also optionally be included (or excluded) from the compositions.

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

The total amount of the mono-, di-, and/or tri-carboxylic acids can vary depending on the type of composition. For example a restructuring composition that is added to chemical treatment composition will typically have a higher amount of the one or more mono-, di-, and/or tri-carboxylic acids because the one more mono-, di-, and/or tri-carboxylic acids become more diluted when the restructuring composition is combined with a chemical treatment composition.

The total amount of mono-, di-, and/or tri-carboxylic acids in a restructuring composition is typically about 1 to about 50 wt.%, based on the total weight of the restructuring composition. In some cases, the total amount of the one or more mono-, di-, and/or tri-carboxylic acids in a restructuring composition is about 1 to about 40 wt.%, about 1 to about 30 wt.%, about 1 to about 25 wt.%, about 1 to about 20 wt.%, about 5 to about 50 wt.%, about 5 to about 40 wt.%, about 5 to about 30 wt.%, about 5 to about 25 wt.%, or about 5 to about 20 wt.%.

When mixed with a hair treatment composition or when the hair restructuring components are already formulated as part of a chemical hair treatment formulation, the total amount of mono-, di-, and/or tri-carboxylic acids will typically be less than the total amount in a restructuring composition. For example, the total amount of mono-, di-, and/or tri-carboxylic acids in a chemical hair treatment composition may be about 0.01 to about 10 wt.%, about 0.01 to about 5 wt.%, about 0.01 to about 4 wt.%, about 0.01 to about 3 wt.%, about 0.1 to about 10 wt.%, about 0.1 to about 5 wt.%, about 0.1 to about 4 wt.%, about 0.1 to about 3 wt.%, about 0.5 to about 4 wt.%, or about 0.5 to about 3 wt.%, based on the total weight of the chemical hair treatment composition.

For example, the shape- altering composition may be left on the hair for up to one hour, such as from about 3 minutes to about 45 minutes, from about 5 minutes to about 30 minutes, or from about 10 minutes to about 20 minutes. In further embodiments, the shape-altering composition may be left on the hair for a period up to about 30 minutes, such as, for example, from about 1 to about 30 minutes, about 1 to about 10 minutes, or about 1 to about 5 minutes. One skilled in the art will, by considering various factors such as starting hair shape and desired hair shape, be able to determine an appropriate amount of time to leave the shape-altering composition on the hair in order to achieve the desired alternation in hair shape.

If desired, the shape-altering composition may, optionally, be shampooed and/or rinsed off the hair.

FORMS

The compositions described herein may be in any suitable physical form. Suitable forms include, but are not limited to low to moderate viscosity liquids, lotions, milks, mousses, sprays, gels, creams, conditioners, and the like.

i. Spray The compositions described herein for treating hair may be in the form of a spray. The spray typically includes a cosmetically acceptable carrier. In some embodiments, the carrier is water or a water and alcohol mixture. The spray formulation optionally includes an antioxidant, sunscreen agent, vitamin, protein, peptide, plant extract, humectant, oil, emollient, lubricant, thickener, hair conditioning agent, polymer, and/or surfactant.

The hair spray formulations may be dispensed from containers that include aerosol dispensers or pump spray dispensers. Such dispensers are known in the art and are commercially available from a variety of manufacturers.

When the hair spray formulation is dispensed from a pressurized aerosol container, a propellant may be used to force the composition out of the container. Suitable propellants include, but are not limited to, a liquefiable gas or a halogenated propellant. Examples of suitable propellants include dimethyl ether and hydrocarbon propellants such as propane, n-butane, iso-butane, CFCs, and CFC-replacement propellants. The propellants may be used singly or admixed.

The amount of propellant may range from about 10% to about 60% by weight of the formulation. The propellant may be separated from the hair repair formulation as in a two compartment container. Other suitable aerosol dispensers are those characterized by the propellant being compressed air, which can be filled into the dispenser using a pump or equivalent device prior to use. Conventional non-aerosol pump spray dispensers, i.e., atomizers, may also be used to apply the hair strengthening formulation to the hair.

ii. Conditioners

The compositions disclosed herein may be in the form of a conditioner. The conditioner may include one or more conditioning agents, such as cationic polymers derived from polysaccharides, for example cationic cellulose derivatives, cationic starch derivatives, cationic guar derivatives and cationic locust bean gum

derivatives, synthetic cationic polymers, mixtures or combinations of these agents. The formulation may comprise other synthetic or natural polymers or polymers derived from biological preparation processes, which are functionalized, where appropriate, for example with cationic or neutral groups. These polymers may have a stabilizing or strengthening action on the compositions, and/or a conditioning action (deposition on the surface of the skin or the hair).

iii. Creams

The compositions disclosed herein for may be in the form of a cream.

Implementation of the present disclosure is provided by way of the following examples. The examples serve to illustrate the technology without being limiting in nature.

Example 2

(Cosmetic Properties)

15 grams of a bleach powder was mixed with 1 5 grams of a beach developer composition, and 4 grams of Formulation 1 , 2, 3, or 4 of Example 1 was added. Each of the four mixtures was separately applied to hair swatches for 35 minutes. After 35 minutes, the swatches were rinsed with water, shampooed once, and blown dry. The components of the bleach composition and the developer composition are provided below.

Bleach Composition

Developer Compositions

The treated hair swatches were evaluated by three independent experts for sensorial characteristics (combability, smoothness, and discipline). Each individual expert ranked the hair swatches according to a four point scale, where "1 " represents the best result and "4" represents the worst result. All three experts arrived at the same conclusions, which are shown below. Combability Smoothness Discipline

No Additive ¹ 4 4 4

Control 1 2 2 2

Control 2 2 2 2

Formulation 1 1 1 1

Formulation 2 1 1 1

Formulation 3 1 1 1

Formulation 4 1 1 1

¹ Hair bleached using only the combination of bleach powder and bleach developer (1 :1 ratio) (no maleic acid, no monoethanolamine, no maleic acid polymer). Hair bleached with no additive provided the worst cosmetic properties, as it was most difficult to comb, it was rough, and exhibited the least amount of discipline. The addition of a di-carboxylic acid (maleic acid or malonic acid) with an amine (monoethanol amine), as with Control 1 and 2, provided some improvement to cosmetic properties. However, the combination of a polymeric acid compound and/or a polymeric acid anhydride compound with the di-carboxylic acid and amine exhibited the very best results, as shown by Formulations 1 -4.

Example 3

(Restructuring Properties)

15 grams of bleach powder was mixed with 15 grams of beach developer, and 4 grams of Formulation 1 of Example 1 was added. Separately, 1 5 grams of the bleach powder was mixed with 15 grams of the beach developer, but no additional components were added (no additives). The bleach composition and the developer were the same as in Example 2 above.

Each mixture was separately applied to hair swatches for a minimum of 50 minutes, or until the treatment with Formulation 1 and the treatment without additives had matching lifts as measured by L ^* a ^* b ^* . The swatches were rinsed with water, shampooed once, and blown dry. The swatches were tested with a Miniature Tensile Tester (MTT) and subjected to Amino Acid Analysis (AAA). The results are presented in the tables below.

Miniature Tensile Tester (MTT)

Amino Acid Analysis

As shown by the data above, both Elastic Modulus and Break Stress are higher when hair is treated with an inventive formulation than when hair is treated with a formulation without additives. Additionally, less cysteic acid is formed when the inventive formulation is used indicating much less damage to the hair. These results demonstrate that hair treated with the inventive formulation (mixture with Formulation 1 ) surprisingly exhibited significantly less damage after chemical treatment and possessed increased strength in comparison to hair treated without the inventive formulation. The foregoing description illustrates and describes the disclosure.
