Description

Title of the invention: Methods for oxidative bleaching or coloring of hair without damaging the hair FIELD OF DISCLOSURE

[0001] The present disclosure relates to methods of oxidative bleaching or coloring of hair that prevent or minimize damage to the hair. Oxidative bleaching or coloring of hair is performed in a routine using a strengthening composition and a conditioning composition. BACKGROUND

[0002] Many consumers wish to use cosmetic and care compositions to enhance the appearance of hair, for example, by changing the color, style and / or shape of the hair and / or by imparting various cosmetic properties to the hair, such as shine and conditioning. Hair can become dry or damaged for a variety of reasons, for example, exposure to the elements, poor nutrition, mechanical treatments (e.g., brushing the hair), styling treatments using chemicals, dyeing, heat, nutrition, etc. Even cleansing products can remove the natural oils from the hair causing dryness, which can lead to a dull appearance and split ends.

[0003] Chemical hair treatments include bleaching and coloring treatments to change the color of the hair. Chemical treatments also include processes to permanently change the shape and structure of the hair, for example, by perming, waving, relaxing, or straightening the hair. These chemical treatments often alter the appearance of the hair by changing its physical structure, which inevitably causes some degree of damage to the hair. Environmental factors, such as salt water, sunlight, and heat, are also known to damage hair. Damaged hair is characterized by unnatural changes in the protein structure of individual hair strands or shafts.

[0004] The popularity and use of oils for hair treatment has increased due to their effectiveness and simplicity. Commonly used oils include olive oil, mineral oil, avocado oil, apricot kernel oil, rice bran oil, and coconut oil. However, these treatments can make hair greasy. Furthermore, effects are usually not seen until several hours (e.g., 8 hours) of treatment and multiple treatments are usually required, making the treatment time-consuming and laborious.

[0005] Hair damage leads to split ends, dryness, Hair that scrunches easily and becomes frizzy and difficult to style. Because the visible part of the hair is dead, it cannot regenerate itself. Many over-the-counter and salon treatments claim to repair damaged hair. These include conditioners, hot oil treatments, hydrolyzed proteins, vitamin formulations, and extracts of exotic fruits, leaves, or roots. However, these treatments provide little improvement to the hair. Therefore, hair treatment technologies that can straighten, relax, or style hair without chemically damaging it are desired.

[0006] There is still a need to remedy the damage caused to hair by the bleaching or oxidative coloring process. SUMMARY OF DISCLOSURE

[0007] The present disclosure relates to methods for oxidatively bleaching or coloring hair. The methods are based on routines using a strengthening composition and a conditioning composition in conjunction with the oxidative bleaching or coloring process. The inventors have discovered that the use of the strengthening composition and the conditioning composition in the claimed routines not only conditions the hair, but surprisingly improves the physical and mechanical properties, and the thermal integrity of the hair fibers, and the improvements are statistically significant. For example, the methods significantly improve the elasticity, strength, and frizz resistance of the hair fibers, as illustrated by statistically significant increases in the modulus of elasticity, breaking stress, and thermal integrity.

[0008] The strengthening composition and the conditioning composition are used in a pre-treatment routine or a post-treatment routine when bleaching or oxidatively coloring hair. The strengthening composition typically includes a. citric acid, a salt thereof, or a combination thereof; b. cyclodextrin, a derivative thereof or a combination thereof;

[0009] wherein a combined total amount of (a) and (b) is from about 2 to about 15% by weight, relative to a total weight of the fortifying composition; a. one or more polyols comprising from 2 to 10 carbon atoms; and b. water.

[0010] The fortifying composition may have a pH of about 2 to about 6, preferably about 2 to about 5. Further, the citric acid, its salt or its combination of (a) and the cyclodextrin, their derivative, or their combination of (b) are typically in a molar ratio of about 20:1 to about 3:1 ((a):(b)) and / or a weight ratio of about 8:1 to about 1:2(a):(b)).

[0011] Citric acid and its salts provide a myriad of benefits to hair. By For example, it acts as an antioxidant, removes buildup and debris from the hair, and improves blood circulation in the scalp, which in turn nourishes hair follicles and promotes growth. Its acidic pH is also useful for balancing the pH of the scalp, as many hair care products make it more alkaline. The citric acid in the present strengthening compositions also interacts with cyclodextrin in a unique way and enhances film formation on the hair, which is further potentiated with heat. Sodium citrate (or trisodium citrate) is an example of a citric acid salt.

[0012] Cyclodextrins are a family of cyclic oligosaccharides composed of a macrocyclic core of glucose subunits joined by α-linkages 1,4 glycosidic. Cyclodextrins are produced from starch by enzymatic conversion. Typical cyclodextrins contain glucose monomers ranging from six to eight units in a core, creating a cone shape, for example, α (alpha)-cyclodextrin has 6 glucose subunits, β (beta)-cyclodextrin has 7 glucose subunits, and γ (gamma)-cyclodextrin has 8 glucose subunits. Non-limiting examples of cyclodextrins for use in the fortifying compositions of the present disclosure include α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin, methyl-α-cyclodextrin, methyl-β-cyclodextrin, methyl-γ-cyclodextrin, and mixtures thereof.

[0013] Preferably, the citric acid, its salt, or combination thereof and the cyclodextrin, its salt, or combination thereof are in association with each other. This may be achieved by independently combining the citric acid, its salt, or combination thereof and the cyclodextrin, its salt, or combination thereof prior to addition to other components of the fortifying composition. For example, the cyclodextrin, its derivative, or its combination is preferably solubilized in citric acid to form a solubilized combination of citric acid and cyclodextrin, their derivative, or combination thereof. The combination may be heated to facilitate or accelerate dissolution of the cyclodextrin. The solubility of cyclodextrin in water is not always ideal.Therefore, combining cyclodextrin with citric acid and dissolving cyclodextrin in citric acid before adding the combination with other components of the fortifying composition may be beneficial.

At the end of the treatment with the revitalizing composition, the strengthening composition and the revitalizing composition are rinsed from the hair.

[0031] The methods described above and throughout the disclosure protect hair from damage due to bleaching or oxidative coloring, strengthen hair, improve curl retention of hair, prevent hair frizz, and / or correct damage to hair caused by bleaching. chemical or hair coloring. BRIEF DESCRIPTION OF THE FIGURES

[0032] An implementation of the present technology will now be described, by way of example only, with reference to the accompanying figures, in which:

[0033] [Fig.l] [Fig.l] shows hair strands treated according to the present disclosure and hair strands treated with comparative routines after being subjected to moisture treatment.

[0034] [Fig.2] [Fig.2] shows strands of hair treated according to the present di vulgation and hair strands treated with comparative routines after being subjected to humidity treatment. DETAILED DESCRIPTION OF THE DISCLOSURE

[0035] A strengthening composition and a conditioning composition are used in the methods of the present disclosure to prevent or minimize damage to hair undergoing an oxidative bleaching or coloring procedure. The strengthening composition may be applied prior to bleaching or oxidative coloring of the hair (as a pre-treatment) or the strengthening composition may also be applied to the hair after bleaching or oxidative coloring of the hair (as a post-treatment). The inventors have discovered that using the strengthening composition and the conditioning composition according to the routines set forth herein surprisingly improves the physical properties of the hair fibers, and the improvements are statistically significant.More specifically, hair treated according to the methods of the present invention exhibits statically significant improvements in elasticity, breaking stress (mechanical strength), and thermal integrity. In addition, hair treated according to the present disclosure exhibits greater resistance to frizz under high humidity conditions, which may be due, at least in part, to the improved elasticity, breaking stress, and thermal integrity.

[0036] According to the pretreatment routine, a strengthening composition is applied to the hair before oxidatively bleaching or coloring the hair. The strengthening composition is applied to the hair and remains on the hair for a first period of time. At the end of the treatment with the strengthening composition (at the end of the first period of time), an oxidative bleaching or coloring composition is layered on the hair, to which the strengthening composition is already applied. The strengthening composition is not rinsed from the hair before the application of the oxidative bleaching or coloring composition. The oxidative bleaching or coloring composition remains on the hair for a period of time sufficient to achieve a desired degree of bleaching or coloring, in which case the bleaching or coloring composition is removed from the hair by cleansing and rinsing the hair with shampoo. After rinsing the shampoo from the hair, the conditioning composition is applied to the hair and remains on the hair for the second duration. At the end of the treatment with the conditioning composition (at the end of the second duration), the conditioning composition is rinsed from the hair. The hair may be dried and / or styled, if desired.

[0037] According to the post-treatment routine, a strengthening composition is not required prior to oxidative bleaching or coloring of the hair. In the post-treatment routine, the hair is bleached or colored with an oxidative bleaching or coloring composition. The oxidative bleaching or coloring composition remains on the hair for a time sufficient to achieve a desired degree of bleaching or coloring, at which point the bleaching or coloring composition is removed from the hair by cleansing and rinsing the hair with shampoo. After rinsing the shampoo from the hair, the hair is treated with a first application of the strengthening composition for a first duration. At the end of the treatment with the first application of the strengthening composition (at the expiration of the first duration), the hair is cleansed with shampoo and the shampoo is rinsed from the hair.After rinsing the shampoo from the hair, the hair is treated with a second application of the strengthening composition for a second duration. At the end of the treatment with the second application of the strengthening composition (at the end of the second duration), without rinsing the second application of the strengthening composition from the hair, the revitalizing composition is applied to the hair, i.e., the revitalizing composition is layered on top of the strengthening composition, which is already applied to the hair. The revitalizing composition remains on the hair for a third duration. At the end of the treatment with the revitalizing composition (at the end of the third duration), the strengthening composition and the revitalizing composition are rinsed from the hair. The hair can then be dried and / or styled, if desired.

Processes I. Pre-processing routine

[0198] According to said “pretreatment routine”, a strengthening composition is applied to the hair to oxidatively bleach or color it before oxidatively bleaching or coloring the hair. The strengthening composition is applied to the hair and left on the hair for a first period of time. The strengthening composition may be applied to wet hair, damp hair, or dry hair. Further, in some embodiments, the hair is cleansed with shampoo before applying the strengthening composition. After rinsing the shampoo from the hair, the hair will be wet or damp. The strengthening composition is then applied to the wet or damp hair and left on the hair for a period of time.For example, the strengthening composition may be applied immediately after rinsing the shampoo from the hair or within about 1 hour, within about 45 minutes, within about 30 minutes, within about 15 minutes, within about 10 minutes, within about 8 minutes, or within about 5 minutes after rinsing the shampoo from the hair.

[0199] The strengthening composition is applied to the hair and left on the hair for a first period of time, which may vary. However, in some embodiments, the strengthening composition remains on the hair for a period of time of about 1 minute to about 1 hour. In other embodiments, the strengthening composition remains on the hair for a period of time of about 1 to about 45 minutes, about 1 to about 30 minutes, about 1 to about 20 minutes, about 1 to about 15 minutes, about 1 to about 10 minutes, about 2 minutes to about 1 hour, about 2 to about 45 minutes, about 2 to about 30 minutes, about 2 to about 20 minutes, about 2 to about 15 minutes, or about 2 to about 10 minutes. The strengthening composition and hair may be massaged or otherwise manipulated to ensure that the strengthening composition comes into contact with most of the hair.

[0200] At the end of the first period, the strengthening composition is not rinsed from the hair. Without rinsing the strengthening composition from the hair, an oxidative bleaching or coloring composition is applied to the hair, i.e. the hair is subjected to an oxidative bleaching or coloring procedure. The bleaching or coloring composition remains on the hair as desired to ensure an acceptable degree of bleaching or coloring. For example, the oxidative bleaching or coloring composition may remain on the hair for about 5 minutes to about 2 hours, about 5 minutes to about 1.5 hours, about 5 minutes to about 1 hour, about 5 minutes to about 45 minutes, about 10 minutes to about 2 hours, about 10 minutes to about 1.5 hours, about 10 minutes to about 1 hour, or about 10 minutes to about 45 minutes.The oxidative bleaching or coloring composition remains on the hair for a time sufficient to achieve a desired degree of bleaching or coloring, which will vary depending on the content of the oxidative bleaching or coloring composition, the desired degree of bleaching or coloring, the original color of the hair, the resilience of the hair to oxidative bleaching and coloring, etc. When the oxidative bleaching or coloring procedure is complete, the hair is cleansed and rinsed. The oxidative bleaching or coloring composition may be initially rinsed from the hair to remove a large portion of the oxidative bleaching or coloring composition and then cleansed with shampoo, and the shampoo is rinsed from the hair. In all cases, after cleansing the hair with shampoo and rinsing the hair, a conditioning composition is applied to the hair.

[0201] The conditioning composition is typically applied to the hair shortly after rinsing the shampoo from the hair and therefore the hair is wet or damp. For example, the conditioning composition may be applied to the hair within about 1 hour of rinsing the shampoo from the hair. In other embodiments, the conditioning composition is applied to the hair within 45 minutes, within 30 minutes, within 20 minutes, within 15 minutes, within 10 minutes, or within 5 minutes of rinsing the shampoo from the hair.

[0202] The conditioning composition is applied to the hair and left on the hair for a second period of time, which will vary. However, in some embodiments, the conditioning composition remains on the hair for a period of time of about 1 minute to about 1 hour. In other embodiments, the conditioning composition remains on the hair for a period of time of about 1 to about 45 minutes, about 1 to about 30 minutes, about 1 to about 20 minutes, about 1 to about 15 minutes, about 1 to about 10 minutes, about 2 minutes to about 1 hour, about 2 to about 45 minutes, about 2 to about 30 minutes, about 2 to about 20 minutes, about 2 to about 15 minutes, or about 2 to about 10 minutes. The conditioning composition and the hair can be massaged or otherwise manipulated to ensure that the conditioning composition comes into contact with most of the hair.

[0203] After the second time period has expired, the conditioning composition is rinsed from the hair. After rinsing the conditioning composition from the hair, the hair is revitalized and strengthened. The hair also exhibits improved curl retention, less frizz, and less propensity to frizz. The method (routine) prevents, reduces, or corrects damage to the hair caused by the oxidative bleaching or coloring process.

[0204] In various embodiments, the methods described above (the pretreatment routine) strengthen hair, improve curl retention, prevent frizz, and / or correct hair damage caused by oxidative bleaching or coloring of the hair to a greater extent than performing the methods (the pretreatment routine) without pretreating the hair with the strengthening composition prior to oxidative bleaching or coloring of the hair.

[0205] In various embodiments, the methods described above (the pre-treatment routine) strengthen hair, improve curl retention, prevent frizz, and / or correct hair damage caused by oxidative bleaching or coloring of hair to a greater extent than performing the method (pre-treatment routine) with a comparative strengthening composition lacking citric acid, a salt thereof, or a combination thereof (i)(a) but is otherwise identical to the strengthening composition of the present disclosure.

[0206] In various embodiments, the methods described above (the pretreatment routine) improve curl retention, prevent frizz, and / or correct hair damage caused by oxidative bleaching or coloring of the hair to a greater extent than performing the method (pretreatment routine) with a comparative strengthening composition lacking cyclodextrin, a salt thereof, or a combination thereof of (i)(b) but is otherwise identical to the strengthening composition of the present disclosure.

[0207] In various embodiments, the methods described above (the pretreatment routine) strengthen hair, improve curl retention, prevent frizz, and / or correct hair damage caused by oxidative bleaching or coloring of hair to a greater extent than performing the methods with a comparative strengthening composition lacking citric acid, a salt thereof, or a combination thereof of (i)(a) but is otherwise identical to the strengthening composition; and strengthen hair, improve curl retention, prevent frizz, and / or correct hair damage caused by oxidative bleaching or coloring of hair to a greater extent than performing the method with a comparative strengthening composition lacking cyclodextrin, a salt thereof, or a combination thereof of (i)(b) but is otherwise identical to the fortifying composition of the present disclosure. II. Post-treatment routine

[0208] According to said "post-treatment routine", a strengthening composition is not applied to the hair to oxidatively bleach or color it before oxidatively bleaching or coloring the hair. Unlike the pre-treatment routine discussed above, in the post-treatment routine, the strengthening compositions are not applied to the hair until the hair has been oxidatively bleached or colored with an oxidative bleaching or coloring composition.

[0209] The oxidative bleaching or coloring composition may be applied to wet hair, damp hair, or dry hair. However, in some embodiments, the hair is shampooed before applying the oxidative bleaching or coloring composition. After rinsing the shampoo from the hair, the hair will be wet or damp. The oxidative bleaching or coloring composition is then applied to the wet or damp hair and left on the hair for a period of time.For example, the oxidative bleaching or coloring composition may be applied immediately after rinsing the shampoo from the hair or within about 1 hour, within about 45 minutes, within about 30 minutes, within about 15 minutes, within about 10 minutes, within about 8 minutes, or within about 5 minutes after rinsing the shampoo from the hair.

[0210] The bleaching or coloring composition remains on the hair as desired to ensure an acceptable degree of bleaching or coloring. For example, the oxidative bleaching or coloring composition may remain on the hair for about 5 minutes to about 2 hours, about 5 minutes to about 1.5 hours, about 5 minutes to about 1 hour, about 5 minutes to about 45 minutes, about 10 minutes to about 2 hours, about 10 minutes to about 1.5 hours, about 10 minutes to about 1 hour, or about 10 minutes to about 45 minutes.The oxidative bleaching or coloring composition remains on the hair for a sufficient time to achieve a desired degree of bleaching or coloring, which will vary depending on the content of the oxidative bleaching or coloring composition, the desired degree of bleaching or coloring, the original color of the hair, the resilience of the hair to oxidative bleaching and coloring, etc. When the oxidative bleaching or coloring procedure is complete, the hair is cleansed and rinsed. The oxidative bleaching or coloring composition may be initially rinsed from the hair for . remove a large part of the bleaching or oxidative coloring composition and further cleaned with shampoo, and the shampoo rinsed from the hair. In any case, after cleaning the hair with shampoo and rinsing the hair, a first application of the strengthening composition is applied to the hair.

[0242] Tests were conducted to investigate how the compositions and methods described throughout the present disclosure influence the integrity of oxidatively bleached or colored hair. Strands of Caucasian hair (2 gm), curl pattern 4 (CP4), were cleansed with a standard shampoo prior to treatment. The bleaching compositions were prepared by mixing a commercial bleaching powder (9% hydrogen peroxide) and a developer (30 Volume) in a ratio of 1:1.5 (Bleaching Powder:Developer (1:1.5)) with the ingredients listed below. Bleaching powder Ingredients: Potassium persulfate, sodium silicate, sodium stearate, magnesium carbonate hydroxide, ammonium persulfate, sodium metasilicate, Cyamopsis tetragonolobus gum / guar gum, liquid paraffin mineral oil, ultramarines, sodium lauryl sulfate, proline, disodium threonine and EDTA Developer (30 V) Ingredients: Aqua / Water, Hydrogen Peroxide (9%), Cetearyl Alcohol, Trideceth-2 Carboxamide MEA, Ceteareth-25, Glycerin, Tetrasodium Etidronate, Tetrasodium Pyrophosphate, Sodium Silicate, Phosphoric Acid

[0243] After cleaning, the hair strands were treated according to one of the following routines:

[0244] Control: The hair strands were oxidatively bleached. A standard bleaching powder and a developer (30 V) were mixed in a ratio of 1:1.5 (Bleaching Powder: Developer (1:1.5)) for the preparation of the bleaching composition. 10 grams of the hair bleaching composition were applied to each hair strand. The hair bleaching composition was left on the hair for 50 minutes. After 50 minutes, the hair bleaching composition was rinsed from the hair and the hair was again cleansed with the standard shampoo. The bleached hair strands were not subjected to any further treatment as a control.

[0245] Comparative 1: The hair strands were treated as described above for the control. However, after cleansing the bleached hair with the standard shampoo (and rinsing the shampoo from the hair), the conditioning composition of Example 2 was immediately applied to the wet or damp hair and left on the hair for 5 minutes. After 5 minutes, the conditioning composition was rinsed from the hair.

[0246] Inventive A: Before oxidative bleaching, the hair strands were pretreated with the inventive strengthening composition A of Example 1. The inventive strengthening composition A was applied to the hair strands (0.4 g per gram of hair), massaged into the hair strands for 1 minute, and left on the hair strands for an additional 5 minutes. Immediately after the additional 5 minutes, the hair strands were bleached as described for the control. After cleansing the bleached hair with the standard shampoo (and rinsing the hair), the conditioning composition of Example 2 was immediately applied to wet or damp hair and left on the hair for 5 minutes. After 5 minutes, the conditioning composition was rinsed from the hair.

[0247] Inventive B: Before oxidative bleaching of the hair, the hair strands were pretreated with the inventive strengthening composition B of Example 1. The inventive strengthening composition B was applied to the hair strands (0.4 g per gram of hair), massaged into the hair strands for 1 minute and left on the hair strands for an additional 5 minutes. Immediately after the additional 5 minutes, the hair strands were bleached as described for the control. After cleansing the bleached hair with the standard shampoo (and rinsing the hair), the conditioning composition of Example 2 was immediately applied to the wet or damp hair and left on the hair for 5 minutes. After 5 minutes, the conditioning composition was rinsed from the hair.

[0248] Inventive C: Before oxidative bleaching of the hair, the hair strands were pretreated with the inventive strengthening composition B of Example 1. The inventive strengthening composition B was applied to the hair strands (0.4 g per gram of hair), massaged into the hair strands for 1 minute and left on the hair strands for an additional 5 minutes. Immediately after the additional 5 minutes, the hair strands were bleached as described for the control. After cleansing the bleached hair with the standard shampoo (and rinsing the hair), the conditioning composition of Example 2 was immediately applied to the wet or damp hair and left on the hair for 5 minutes. After 5 minutes, the conditioning composition was rinsed from the hair.

[0249] Hair treated according to the protocols described above was analyzed by miniature tensile tests (Young's modulus and breaking stress) and by differential scanning calorimetry (thermal integrity). One-way analysis of variance using SPSS software with 95% confidence interval was used to analyze significant differences in DSC and MTT results. Hair frizz was also evaluated. Modulus of elasticity and breaking stress

[0250] The hair was analyzed with miniature tensile tests (Miniature Tensile Tester, MTT-675, Dia-Stron Ltd). The MTT was used to measure Young's modulus, i.e., the slope of the initial portion of the stress-strain curve, which is adjusted to make a cross-section, representing a measure of the spring-like structure of the hair. It also measures the breaking stress, which is the total force required to break the hair fiber. The test results were subjected to statistical analysis using Tukey-Kramer post-hoc tests with k=3, to determine and exclude significant outliers. Statistical significance was analyzed using SPSS software at 95% confidence. The results are presented in the table below and the corresponding figures. The elastic modulus represents the elastic properties of the fiber. Higher values ​​represent higher elasticity, indicating that the hair is less brittle due to fortification and lack of dryness and damage.

[0252] The statistical significance of the elastic modulus is as follows: LB > LA = LC > Control = CL The statistical significance of the breaking stress is as follows: IB > LA = LC > Control = CL The data show that inventive routine B outperforms inventive routines A and C; and that inventive routines A and C outperforms the control and comparative routine 1.

[0253] Thermal integrity / protein crosslinking density

[0254] Hair was analyzed by differential scanning calorimetry (DSC, DSC-2500, TA Instruments). DSC was used to measure the denaturation temperature, which is a measure of the thermal stability of proteins in hair and is a representation of protein crosslink density. Higher values ​​represent higher thermal integrity, which is an indication of more crosslinking (stronger hair).

[0256] The statistical significance of the crosslink density is as follows: LA = LC > IB > Cl > Control. The inventive routines LA and LC outperformed the inventive routine LB; and the inventive routine LB outperformed the comparative routine Cl, which outperformed the control. Frizz Tests

[0257] The strands treated according to the protocols outlined above were placed in a humidity chamber at 25°C and 80% relative humidity. After 4 hours, the samples were removed from the humidity chamber and visually analyzed. Snapshots of the hair strands are shown in [Fig.l]. The results show that the hair pretreated with the strengthening compositions of Example 1 suffered less frizz and retained better shape and curls.

[0259] After cleaning, the hair strands were treated according to one of the following routines:

[0260] Control: The hair strands were oxidatively bleached. A standard bleaching powder and a developer (30 V) were mixed in a ratio of 1:1.5 (Bleaching Powder: Developer (1:1.5)) for the preparation of the bleaching composition. 10 grams of the hair bleaching composition were applied to each hair strand. The hair bleaching composition was left on the hair for 50 minutes. After 50 minutes, the hair bleaching composition was rinsed from the hair and the hair was cleansed with shampoo. The bleached hair strands were not subjected to any further treatment as a control.

[0261] Comparative 1: The hair strands were bleached as described above for the control. However, after cleansing the bleached hair with shampoo (and rinsing the shampoo from the hair), the conditioning composition of Example 2 was immediately applied to the wet or damp hair and left on the hair for 5 minutes. After 5 minutes, the conditioning composition was rinsed from the hair.

[0262] Inventive A: The hair strands were bleached as described above for the control. However, after cleansing the bleached hair with shampoo (and rinsing the shampoo from the hair), the inventive strengthening composition A was applied to the hair strands (0.4 g per gram of hair), massaged into the hair strands for 1 minute, and left on the hair strands for an additional 5 minutes. After the additional 5 minutes, the hair strands were cleansed with a standard shampoo and the shampoo was rinsed from the hair. Immediately after rinsing the hair, the inventive strengthening composition A was applied to the hair strands (0.4 g per gram of hair) again (a second time), massaged into the hair strands for 1 minute, and left on the hair strands for an additional 5 minutes.Immediately after the additional 5 minutes, without rinsing the inventive strengthening composition A from the hair, the revitalizing composition of Example 2 was . applied to hair, left on hair for 5 minutes, and rinsed from hair.

[0263] Inventive B: The hair strands were bleached as described above for the control. However, after cleansing the bleached hair with shampoo (and rinsing the shampoo from the hair), the inventive strengthening composition B of Example 1 was applied to the hair strands (0.4 g per gram of hair), massaged into the hair strands for 1 minute, and left on the hair strands for an additional 5 minutes.

[0265] Hair treated according to the protocols described above was analyzed by miniature tensile tests (modulus of elasticity and breaking stress) and by differential scanning calorimetry (thermal integrity). One-way analysis of variance was used to determine statistical significance among the control and the inventive composition at 95% confidence. Hair frizz was also evaluated. Modulus of elasticity and breaking stress

[0266] The hair was analyzed with miniature tensile tests (Miniature Tensile Tester, MTT-675, Dia-Stron Ltd). The MTT is used to measure the elastic modulus. It also measures the breaking strain, which is the total force required to break the hair fiber. The test results were subjected to statistical analysis using Tukey-Kramer post-hoc tests with IBM SPSS statistical analysis software. One-way analysis of variance was used to determine statistical significance among the control and the inventive composition. The results are presented in the table below and the corresponding figures. The elastic modulus represents elasticity. Higher values ​​represent higher elasticity, indicating that the hair is less brittle due to fortification and lack of dryness and damage.

[0267] [Tables5] Results MTT Control Cl IA LB LC Modulus of elasticity (MPa) 1072 + 192 1021 + 274 1281 + 240 1810 + 493 1255 + 278 Statistical significance (p<0.05) aabcb Breaking stress 131 + 24 136 + 22 146+15 183 + 22 146 + 16 Statistical significance (p< 0.05) aabcb

[0268] The statistical significance of the modulus of elasticity is as follows: LB > LA = LC > Control = CL The statistical significance of the breaking stress is as follows: IB > LA = LC > Control = CL Thus, inventive routine B performed better than inventive routines LA and LC; and inventive routines LA and LC performed better than the control.

[0269] Hair was analyzed by differential scanning calorimetry (DSC, DSC-2500, TA Instruments). DSC is used to measure denaturation temperature, which is a measure of the thermal stability of proteins in hair and a representation of crosslink density. Higher values ​​represent higher thermal integrity, indicating more crosslink formation with hair bonds (stronger hair).

[0270] [Tableauxô] DSC Results Control Cl IA LB LC Crosslinking density (°C) 143.8 ± 0.1 146.9 ± 0.2 159.3 ± 0.1 157.7 ± 0.2 157.8 ± 0.1 Statistical significance (p<0.05) abdcc

[0271] The statistical significance of the crosslink density is as follows: LA > LB = IC > Cl > Control. Thus, the inventive routine LA outperformed the inventive routines LB and LC; and the inventive routines LB and LC outperformed the comparative routine 1, which outperformed the control. Frizz tests

[0272] The strands treated according to the protocols outlined above were placed in a humidity chamber at 25°C and 80% relative humidity. After 4 hours, the samples were removed from the humidity chamber and visually analyzed. Snapshots of the hair strands are shown in [Fig.2]. The results show that the hair pretreated with the strengthening compositions of Example 1 suffered less frizz and retained better shape and curls.

[0273] The foregoing description illustrates and describes the disclosure. Furthermore, the disclosure shows and describes only the preferred embodiments. However, as mentioned above, it is to be understood that it is capable of use in various other combinations, modifications, and environments and is capable of changes or modifications within the scope of the inventive concepts as expressed herein, consistent with the above teachings and / or the skill or knowledge of the relevant art. The embodiments described herein are further intended to explain the best modes known to the applicant and to enable others skilled in the art to use the disclosure in such or other embodiments and with the various modifications required by the particular applications or uses thereof.Accordingly, the description is not intended to limit the invention to the form disclosed herein. The appended claims are also intended to be construed to include other embodiments.

[0274] As used herein, the terms "comprising," "having," and "including" are used in their broad and non-limiting sense.

[0275] The terms “a”, “an”, “the” and “the” are understood to include the plural and the singular.

[0276] Thus, the phrase "a mixture thereof" also relates to "mixtures thereof." Throughout the disclosure, the phrase "their mixture" is used, after a list of elements as shown in the following example where the letters A through F represent the elements: "one or more elements selected from the group consisting of A, B, C, D, E, F, and their mixture." The phrase "their mixture" does not require that the mixture include all of A, B, C, D, E, and F (although all of A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of two or more of A, B, C, D, E, and F may be included. In other words, it is equivalent to the formulation "one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture of two or more of A, B, C, D, E, and F."

[0277] Similarly, the expression "their salt" also relates to "their salts". Thus, when the disclosure refers to "an element selected from the group consisting of A, B, C, D, E, F, their salt, and a mixture thereof", it indicates that one or more of A, B, C, D and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included, or a mixture of any two of A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included.

[0278] Salts referred to throughout the disclosure may include salts having a counterion such as an alkali metal, an alkaline earth metal, or an ammonium counterion. This list of counterions, however, is not limiting. Suitable counterions for the components described herein are known in the art.

[0279] The expression “one or more” means “at least one” and therefore includes individual components as well as mixtures / combinations.

[0280] The term “plurality” means “more than one” or “two or more.”

[0281] Except in working examples, or if otherwise indicated, all numbers expressing amounts of ingredients and / or reaction conditions may be modified in all cases by the term "about", meaning to within + / - 5% of the number indicated.

[0282] All percentages, parts and ratios herein are based on the total weight of the compositions of the present invention, unless otherwise indicated.

[0283] Some of the various categories of components identified may overlap. In such cases where an overlap may exist and the composition includes both components (or the composition includes more than two overlapping components), an overlapping compound does not represent more than one component. For example, some compounds may be considered both a nonionic surfactant or emulsifier and a fatty compound. If a particular composition includes both a nonionic surfactant or emulsifier and a fatty compound, a compound single will serve only as a non-ionic surfactant or emulsifier or only as a fat component (the single compound does not serve as both a non-ionic surfactant or emulsifier and a fat component).

[0284] As used herein, all ranges provided are intended to include each specific range within the given ranges, as well as a combination of sub-ranges between the given ranges. Thus, a range of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as sub-ranges such as 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc. All ranges and values ​​disclosed herein are inclusive and combinable. For example, any value or point described herein that falls within a range described herein may serve as a minimum or maximum value to infer a sub-range, etc.

[0285] The compositions of the present case may optionally include one or more surfactants and / or emulsifiers other than the nonionic surfactants and emulsifiers described above, for example, one or more nonionic, anionic, cationic and / or amphoteric / zwitterionic surfactants.

[0286] The terms "surfactants" and "emulsifiers" include salts of surfactants and emulsifiers even if not explicitly stated. In other words, whenever the disclosure refers to a surfactant or emulsifier, it is intended that salts also be encompassed to the extent that such salts exist, even though the specification may not specifically refer to a salt (or may not refer to a salt in all instances throughout the disclosure), for example, by using language such as "their salt" or "their salts." Sodium and potassium are common cations that form salts with surfactants and emulsifiers. However, additional cations such as ammonium ions, or alkanolammonium ions such as monoethanolammonium or triethanolammonium ions, may also form surfactant salts.

[0287] The term "substantially free" or "essentially free" as used herein means that less than about 2% by weight of a specific material is added to a composition, based on the total weight of the compositions. However, the compositions may include less than about 1% by weight, less than about 0.5% by weight, less than about 0.1% by weight, or none of the specified material.

[0288] Any components positively presented in the present disclosure may be negatively excluded from the claims, for example, a claimed composition may be "free", "essentially free" (or "substantially free") of one or more components that are positively presented in the present disclosure. Furthermore, components, compounds or ingredients described for use in the strengthening composition may be excluded from the revitalizing compositions, and vice versa.
