[0001] Cross-references to related applications

[0002] This application claims priority to U.S. Patent Application Nos. 18 / 355,533 and 18 / 355,526, filed July 20, 2023, and French Patent Application Nos. FR2310335 and FR2310312, filed September 28, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to methods and compositions for oxidative bleaching or dyeing hair, which prevent or minimize damage to the hair; and to methods and compositions for treating oxidatively bleached or dyed hair. Oxidative bleaching or dyeing of hair is carried out through conventional processes using strengthening and conditioning compositions. Background Technology

[0004] Many consumers use cosmetic and conditioning products to improve the appearance of their hair, such as by changing its color, style, or shape, and / or by giving it various styling properties, such as shine and conditioning. Hair can become dry or damaged for a variety of reasons, such as wind and sun exposure, malnutrition, mechanical damage (e.g., combing), chemical styling, dyeing, heat, and more. Even cleaning products can remove the hair's natural oils, leading to dryness, which in turn results in a dull, split, and frizzy appearance.

[0005] Chemical treatments for hair include bleaching and dyeing to change hair color. Chemical treatments also include procedures that permanently alter the shape and structure of hair, such as perming, waving, relaxing, or straightening. These chemical treatments change the appearance of hair by altering its physical structure, which inevitably causes some degree of damage. Environmental factors, such as seawater, sunlight, and high temperatures, are also known to damage hair. Damaged hair is characterized by unnatural changes in the protein structure of individual hair strands or the hair shaft.

[0006] The popularity and use of oils for hair treatments have increased due to their effectiveness and ease of use. Commonly used oils include olive oil, mineral oil, avocado oil, apricot kernel oil, rice bran oil, and coconut oil. However, these treatments can leave hair feeling greasy. Furthermore, they typically require several hours (e.g., 8 hours) or more to see results and often need to be done multiple times, making them both time-consuming and laborious.

[0007] Damaged hair can lead to split ends, dryness, breakage, and frizziness that makes it difficult to manage. Because the visible portion of the hair is dead, it lacks the ability to regenerate. Many treatments on the market and in hair salons claim to repair damaged hair. These include conditioning products, hot oil treatments, hydrolyzed proteins, vitamin supplements, and extracts from exotic fruits, leaves, or roots. However, these treatments offer limited improvement. Therefore, there is a pressing need for hair treatment techniques that can straighten, smooth, or style hair without damaging it.

[0008] Damage to the hair caused by oxidative bleaching or dyeing processes still needs to be repaired. Summary of the Invention

[0009] This invention relates to methods and compositions for oxidative bleaching or dyeing hair. These methods are based on conventional processes that combine strengthening and conditioning compositions in an oxidative bleaching or dyeing process. The inventors have discovered that using strengthening and conditioning compositions in the claimed conventional processes not only conditions the hair but also surprisingly improves the physical and mechanical properties and thermal integrity of the hair fibers, and these improvements are statistically significant. These methods and compositions can also repair damage to hair caused by previous chemical bleaching or dyeing. For example, these methods significantly improve the elasticity, strength, and frizz resistance of hair fibers, as evidenced by statistically significant increases in elastic modulus, breaking stress, and thermal integrity.

[0010] When oxidative bleaching or dyeing hair, strengthening and conditioning compositions can be used in pre-treatment or post-treatment processes. Strengthening compositions typically contain...

[0011] (a) Citric acid, its salts, or combinations thereof; (b) Cyclodextrins, their derivatives, or combinations thereof; The total amount of (a) and (b) is about 2 to about 15 wt.%, based on the total weight of the reinforcing composition; (c) One or more polyols having 2 to 10 carbon atoms; and (d) Water.

[0012] The pH of the fortifying composition is from about 2 to about 6, preferably from about 2 to about 5. In addition, the molar ratio of citric acid, its salt or combination thereof in (a) to cyclodextrin, its derivative or combination thereof in (b) is generally from about 20:1 to about 3:1 ((a):(b)), and / or the weight ratio is from about 8:1 to about 1:2 ((a):(b)).

[0013] Citric acid and its salts offer numerous benefits to hair. For example, as an antioxidant, it removes buildup and dirt from hair and improves scalp blood circulation, thereby nourishing hair follicles and promoting hair growth. Its acidic pH also helps balance the scalp's pH, as many hair care products make the scalp alkaline. The citric acid in this strengthening composition also interacts with cyclodextrin in a unique way, improving film-forming effects on the hair surface, and this effect is further enhanced by heating. Sodium citrate (or trisodium citrate) is an example of a citrate salt.

[0014] Cyclodextrins are a class of cyclic oligosaccharides composed of macrocycles formed by glucose subunits linked by α-1,4 glycosidic bonds. Cyclodextrins are produced through the enzymatic conversion of starch. Typical cyclodextrins contain 6 to 8 glucose monomers forming a conical ring. For example, α-cyclodextrin contains 6 glucose subunits, β-cyclodextrin contains 7 glucose subunits, and γ-cyclodextrin contains 8 glucose subunits. Non-limiting examples of cyclodextrins used in the fortified compositions of this disclosure include α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin, methyl-α-cyclodextrin, methyl-β-cyclodextrin, methyl-γ-cyclodextrin, and mixtures thereof.

[0015] Preferably, citric acid, its salts, or combinations thereof are associated with cyclodextrin, its salts, or combinations thereof. This can be achieved by mixing citric acid, its salts, or combinations thereof with cyclodextrin, its salts, or combinations thereof separately before adding other components to the fortifying composition. For example, it is preferable to dissolve cyclodextrin, its derivatives, or combinations thereof in citric acid to form a soluble combination of citric acid and cyclodextrin, its derivatives, or combinations thereof. This combination can be heated to promote or accelerate the dissolution of cyclodextrin. The solubility of cyclodextrin in water is not always ideal. Therefore, it may be beneficial to mix and dissolve cyclodextrin in citric acid before adding this combination to the fortifying composition along with other components.

[0016] Non-limiting examples of polyols having 2 to 10 carbon atoms include ethylene glycol, propylene glycol, butanediol, hexanediol, pentanediol, 1,3-propanediol, diethylene glycol, dipropylene glycol, octyl glycol, and glycerol.

[0031] As previously stated, strengthening and conditioning compositions can be used for pretreatment or post-treatment. In a pretreatment process, the strengthening composition is applied to the hair prior to oxidative bleaching or coloring and remains on the hair while the oxidative bleaching or coloring composition is applied; that is, the strengthening composition is not rinsed off the hair before oxidative bleaching or coloring. Instead, the oxidative bleaching or coloring composition is "layered" on top of the strengthening composition already applied to the hair. However, the conditioning composition is applied to the hair after the oxidative bleaching or coloring process is complete. After the oxidative bleaching or coloring process is complete, the oxidative bleaching or coloring composition is removed from the hair by shampooing. After rinsing the shampoo off the hair, the hair is treated with the conditioning composition.

[0032] As the name suggests, in the post-treatment process, the strengthening composition is applied to the hair after oxidative bleaching or dyeing. The hair is initially bleached or dyed with an oxidative bleaching composition or dyeing composition, and then rinsed off. After rinsing off the oxidative bleaching composition or dyeing composition, the hair is treated with a first-agent strengthening composition. After treatment with the first-agent strengthening composition, the hair is shampooed. The first-agent strengthening composition is not rinsed off before shampooing. After rinsing off the shampoo, the hair is treated with a second-agent strengthening composition. Subsequently, without rinsing off the second-agent strengthening composition, a conditioning composition is applied to the hair, layering the conditioning composition over the strengthening composition already applied. After treatment with the conditioning composition, both the strengthening composition and the conditioning composition are rinsed off the hair.

[0033] The methods described above, as well as those described throughout this disclosure, protect hair from damage caused by oxidative bleaching or dyeing, strengthen hair, improve hair curl retention, prevent hair frizz, and / or repair damage to hair caused by chemical bleaching or dyeing.

[0034] Brief description of the attached figures

[0035] The following describes the specific implementation of this technology using only examples and with reference to the accompanying drawings, wherein: Figure 1 The images show hair strands processed according to this disclosure and hair strands treated with a comparative procedure after a humidity treatment.

[0036] Figure 2 The images show hair strands processed according to this disclosure and hair strands treated with a comparative procedure after a humidity treatment.

[0037] Figure 3 The images show hair strands processed according to this disclosure and hair strands treated with a comparative procedure after a humidity treatment. Invention Details

[0039] The methods disclosed herein use strengthening and conditioning compositions to prevent or minimize damage to hair subjected to oxidative bleaching or dyeing processes. The strengthening composition may be applied prior to oxidative bleaching or dyeing (as a pretreatment), or it may be applied to the hair after oxidative bleaching or dyeing (as a posttreatment). The inventors have found that using the strengthening and conditioning compositions according to the procedures described herein surprisingly improves the physical properties of hair fibers, and these improvements are statistically significant. Specifically, hair treated according to the methods of this disclosure exhibits statistically significant improvements in elasticity, breaking stress (strength), and thermal integrity. Furthermore, hair treated according to this disclosure exhibits greater resistance to frizz under high humidity conditions, which may be at least partly attributable to the improved elasticity, breaking stress, and thermal integrity.

[0040] According to the pretreatment procedure, a strengthening composition is applied to the hair before oxidative bleaching or dyeing. The strengthening composition is applied to the hair and allowed to remain on the hair for a first time period. After treatment with the strengthening composition is complete (i.e., at the end of the first time period), an oxidative bleaching composition or dyeing composition is layered on top of the strengthened composition already applied to the hair. The strengthening composition is not rinsed off the hair before applying the oxidative bleaching composition or dyeing composition. The oxidative bleaching composition or dyeing composition remains on the hair long enough to achieve the desired bleaching or dyeing level, at which point the bleaching composition or dyeing composition is removed from the hair by shampooing and rinsing. After rinsing off the shampoo, a conditioning composition is applied to the hair and allowed to remain on the hair for a second time period. After treatment with the conditioning composition is complete (i.e., at the end of the second time period), the conditioning composition is rinsed off the hair. If necessary, the hair can be blow-dried and / or styled.

[0041] According to the post-treatment procedure, the strengthening composition is not used before oxidative bleaching or dyeing. In the post-treatment procedure, the hair is bleached or dyed with an oxidative bleaching or dyeing composition. The oxidative bleaching or dyeing composition remains on the hair for a sufficient time to achieve the desired degree of bleaching or dyeing, at which point the bleaching or dyeing composition is removed from the hair by washing and rinsing with shampoo. After rinsing the shampoo off the hair, the hair is treated with the strengthening composition applied as a first agent for a first time period. After the treatment with the first strengthening composition is completed (i.e., at the end of the first time period), the hair is washed with shampoo and the shampoo is rinsed off the hair. After rinsing the shampoo off the hair, the hair is treated with the second strengthening composition as a second time period. After the treatment with the second strengthening composition is completed (i.e., at the end of the second time period), without rinsing off the second strengthening composition, a conditioning composition is applied to the hair, i.e., a conditioning composition is layered on top of the strengthening composition already applied to the hair. The conditioning composition remains on the hair for a third time period. After the treatment with the conditioning composition is complete (i.e., at the end of the third time interval), rinse the strengthening and conditioning compositions off the hair. Then, if necessary, blow-dry and / or style the hair.

[0042] A more detailed discussion of the pretreatment and posttreatment procedures is described under the heading "Methods". Details of the fortifying and conditioning compositions follow thereafter.

[0045] The total amount of citric acid, its salts, or combinations thereof may vary. However, in various embodiments, the fortifying composition comprises about 1 to about 5 wt.% of citric acid, its salts, or combinations thereof (based on the total weight of the composition). In other embodiments, the fortifying composition comprises about 1 to about 4 wt.%, about 1 to about 3 wt.%, about 2 to about 5 wt.%, about 2 to about 4 wt.%, about 2 to about 3 wt.%, about 2.5 to about 5 wt.%, about 2.5 to about 4 wt.%, about 2.5 to about 3 wt.%, or about 1, about 1.5, about 2, about 2.5, about 3, about 3.5, about 4, about 4.5, or about 5 wt.% of citric acid, its salts, or combinations thereof, based on the total weight of the fortifying composition.

[0046] (b) Cyclodextrins and their derivatives

[0047] The fortified compositions according to this disclosure comprise at least one cyclodextrin or a derivative thereof. As used herein, the term "cyclodextrin" includes carboxylates, whether or not explicitly stated. Cyclodextrins are a class of cyclic oligosaccharides composed of macrocyclic structures of glucose subunits linked by α-1,4 glycosidic bonds.

[0048] Cyclodextrins that can be used include those having the following formula:

[0049] in: R is selected from H, CH3, or hydroxypropyl.

[0050] The range of n is 6-8.

[0051] For example, in an implementation where R=H, the cyclodextrin can be α-cyclodextrin (n = 6), β-cyclodextrin (n = 7), or γ-cyclodextrin (n = 8). For instance, α-cyclodextrin sold by WACKER under the trade name CAVAMAX W6 PHARMA, β-cyclodextrin sold by WACKER under the trade name CAVAMAX W7 PHARMA, or γ-cyclodextrin sold by WACKER under the trade name CAVAMAX W8 PHARMA can be used.

[0052] In other embodiments, where R = CH3, the cyclodextrin can be a methylcyclodextrin, such as methyl-α-cyclodextrin (n = 6), methyl-β-cyclodextrin (n = 7), or methyl-γ-cyclodextrin (n = 8). For example, methyl-β-cyclodextrin marketed by Wacker Chemie under the name CAVASOL W7 can be used.

[0053] In various embodiments, the at least one cyclodextrin may comprise a mixture of cyclodextrins and / or their derivatives. For example, the at least one cyclodextrin may be a mixture of α-cyclodextrin, β-cyclodextrin, and / or γ-cyclodextrin. In another embodiment, the at least one cyclodextrin comprises β-cyclodextrin. In yet another further embodiment, the cyclodextrin is only β-cyclodextrin, and no other cyclodextrins or their derivatives are present in the fortifying composition.

[0054] In one embodiment, the fortifying composition of this disclosure comprises β-cyclodextrin in an amount of about 0.1% to about 10%, for example, 0.2% to about 8%, about 0.3% to about 7%, about 0.4% to about 6%, about 1% to about 10%, about 1% to about 8%, about 1% to about 5%, about 1% to about 3 wt.%, based on the total weight of the fortifying composition.

[0055] The total amount of cyclodextrin, its derivatives, or combinations thereof in the fortifying composition may vary. However, in various embodiments, the fortifying composition comprises about 0.5 to about 5 wt.% of cyclodextrin, its derivatives, or combinations thereof, based on the total weight of the fortifying composition. In other embodiments, the fortifying composition comprises 0.5 to about 4 wt.%, about 0.5 to about 3 wt.%, about 0.5 to about 2 wt.%, about 1 to about 5 wt.%, about 1 to about 4 wt.%, about 1 to about 3 wt.%, about 1 to about 2 wt.%, about 1.5 to about 5 wt.%, about 1.5 to about 4 wt.%, about 1.5 to about 3 wt.%, about 1.5 to about 2 wt.%, about 0.5 wt.%, about 1 wt.%, about 1.25 wt.%, about 1.5 wt.%, about 2 wt.%, about 2.5 wt.%, about 3 wt.%, about 3.5 wt.%, about 4 wt.%, about 4.5 wt.%, or about 5 wt.% of cyclodextrin, its derivatives, or combinations thereof, based on the total weight of the fortifying composition.

[0056] Combination of citric acid / salt and cyclodextrin

[0057] The total amount of (i)(a) citric acid, its salts or combinations thereof, and (b) cyclodextrin, its derivatives or combinations thereof may vary. However, in various embodiments, the total amount of (i)(a) citric acid, its salts or combinations thereof, and (i)(b) cyclodextrin, its derivatives or combinations thereof, based on the total weight of the fortifying composition, is about 2 to about 15 wt.%. In other embodiments, the total amount of (i)(a) citric acid, its salts or combinations thereof, and (i)(b) cyclodextrin, its derivatives or combinations thereof, is about 2 to about 12 wt.%, about 2 to about 10 wt.%, about 2 to about 8 wt.%, about 2 to about 6 wt.%, about 2 to about 5 wt.%, about 3 to about 12 wt.%, about 3 to about 10 wt.%, about 3 to about 8 wt.%, about 3 to about 6 wt.%, about 3 to about 5 wt.%, or about 2 wt.%, 3 wt.%, 4 wt.%, 5 wt.%, 6 wt.%, 7 wt.%, or 8 wt.%, based on the total weight of the fortifying composition.

[0058] The weight ratio of (i)(a) citric acid, its salts or combinations thereof to (i)(b) cyclodextrin, its derivatives or combinations thereof may vary. However, in one embodiment, the weight ratio of (i)(a) citric acid, its salts or combinations thereof to (i)(b) cyclodextrin, its derivatives or combinations thereof is about 8:1 to 1:2 ((i)(a):(i)(b)). In other embodiments, the weight ratio of (i)(a) citric acid, its salts or combinations thereof to (i)(b) cyclodextrin, its derivatives or combinations thereof is 6:1 to about 1:2, about 5:2 to about 1:2, about 4:1 to about 1:2, about 3:1 to about 1:2, about 2:1 to about 1:2, about 8:1 to about 1:1, about 6:1 to about 1:1, about 5:1 to about 1:1, about 4:1 to about 1:1, about 3:1 to about 1:1, about 2:1 to about 1:1, about 1.2:1, about 1.3:1, about 1.4:1, about 1.5:1, about 1.6:1, about 1.7:1 or about 1.8:1 ((i)(a):(i)(b)).

[0059] The molar ratio of (i)(a) citric acid, its salts or combinations thereof to (i)(b) cyclodextrin, its derivatives or combinations thereof may vary. However, in some embodiments, the molar ratio of (i)(a) citric acid, its salts or combinations thereof to (i)(b) cyclodextrin, its derivatives or combinations thereof is about 20:1 to about 3:1.

[0060] In one embodiment, (i)(a) citric acid, its salts, or combinations thereof are first mixed with (i)(b) cyclodextrin, its derivatives, or combinations thereof, and then added to the fortified composition of this disclosure. For example, it is preferable to dissolve the cyclodextrin, its derivatives, or combinations thereof in citric acid to form a soluble combination of citric acid and cyclodextrin. This combination may be heated to promote or accelerate the dissolution of the cyclodextrin. The solubility of cyclodextrin in water is not always ideal. Therefore, it may be advantageous to mix and dissolve the cyclodextrin in citric acid before combining this combination with other components of the fortified composition.

[0061] (c) Polyols having 2 to 10 carbon atoms

[0062] One or more polyols in the reinforcing composition have 2 to 10 carbon atoms. Preferably, these polyols also have two or three hydroxyl groups. For example, these polyols may be selected from glycols and glycerol. Non-limiting examples of polyols having 2 to 10 carbon atoms include ethylene glycol, propylene glycol, butanediol, hexanediol, pentanediol, 1,3-propanediol, diethylene glycol, dipropylene glycol, octyl glycol, and glycerol.

[0063] The total amount of polyols having 2 to 10 carbon atoms may vary. However, in some embodiments, the reinforcing composition comprises about 0.1 wt.% to about 25 wt.% of one or more polyols having 2 to 10 carbon atoms, based on the total weight of the reinforcing composition.

[0212] method

[0213] I. Preprocessing flow

[0214] According to a so-called "pretreatment process," a strengthening composition is applied to the hair to be oxidatively bleached or dyed before oxidative bleaching or dyeing. The strengthening composition is allowed to remain on the hair for an initial period of time after application. The strengthening composition can be applied to wet, semi-dry, or dry hair. Furthermore, in some embodiments, the hair is shampooed before applying the strengthening composition. After rinsing off the shampoo, the hair will be wet or semi-dry. The strengthening composition is then applied to the wet or semi-dry hair and allowed to remain on the hair for a period of time. For example, the strengthening composition can be applied immediately after rinsing off the shampoo, or within approximately 1 hour, approximately 45 minutes, approximately 30 minutes, approximately 15 minutes, approximately 10 minutes, approximately 8 minutes, or approximately 5 minutes after rinsing off the shampoo.

[0215] The strengthening composition is applied to the hair and allowed to remain on the hair for an initial period of time, which varies in length. However, in some embodiments, the strengthening composition remains on the hair for approximately 1 minute to approximately 1 hour. In further embodiments, the strengthening composition remains on the hair for approximately 1 to approximately 45 minutes, approximately 1 to approximately 30 minutes, approximately 1 to approximately 20 minutes, approximately 1 to approximately 15 minutes, approximately 1 to approximately 10 minutes, approximately 2 minutes to approximately 1 hour, approximately 2 to approximately 45 minutes, approximately 2 to approximately 30 minutes, approximately 2 to approximately 20 minutes, approximately 2 to approximately 15 minutes, or approximately 2 to approximately 10 minutes. The strengthening composition and hair may be massaged or otherwise treated to ensure that the strengthening composition makes contact with the majority of the hair.

[0216] At the end of the first time period, the strengthening composition is not rinsed off the hair. Without rinsing off the strengthening composition, an oxidative bleaching or coloring composition is applied to the hair, even if the hair has undergone an oxidative bleaching or coloring process. The bleaching or coloring composition remains on the hair as needed to ensure an acceptable level of bleaching or coloring is achieved. For example, the oxidative bleaching or coloring composition may remain on the hair for approximately 5 minutes to approximately 2 hours, approximately 5 minutes to approximately 1.5 hours, approximately 5 minutes to approximately 1 hour, approximately 5 minutes to approximately 45 minutes, approximately 10 minutes to approximately 2 hours, approximately 10 minutes to approximately 1.5 hours, approximately 10 minutes to approximately 1 hour, or approximately 10 minutes to approximately 45 minutes. The time the oxidative bleaching or coloring composition remains on the hair sufficient to achieve the desired level of bleaching or coloring will vary depending on the amount of oxidative bleaching or coloring composition, the desired level of bleaching or coloring, the original color of the hair, and the hair's tolerance to oxidative bleaching and coloring. When the oxidative bleaching or coloring process is complete, the hair is cleaned and rinsed. The oxidative bleaching or dyeing composition can initially be rinsed off the hair to remove most of it, followed by further cleaning with shampoo, which is then rinsed off. In any case, after cleaning the hair with shampoo and rinsing it off, the conditioning composition is applied to the hair.

[0217] The conditioning composition is typically applied to the hair shortly after rinsing off the shampoo, and thus the hair is damp or semi-dry. For example, the conditioning composition may be applied to the hair within approximately one hour after rinsing off the shampoo. In a further embodiment, the conditioning composition may be applied to the hair within 45 minutes, 30 minutes, 20 minutes, 15 minutes, 10 minutes, or 5 minutes after rinsing off the shampoo.

[0218] The conditioning composition is applied to the hair and allowed to remain on the hair for a second period of time, which varies in duration. Nevertheless, in some embodiments, the conditioning composition remains on the hair for approximately 1 minute to approximately 1 hour. In further embodiments, the conditioning composition remains on the hair for approximately 1 to approximately 45 minutes, approximately 1 to approximately 30 minutes, approximately 1 to approximately 20 minutes, approximately 1 to approximately 15 minutes, approximately 1 to approximately 10 minutes, approximately 2 minutes to approximately 1 hour, approximately 2 to approximately 45 minutes, approximately 2 to approximately 30 minutes, approximately 2 to approximately 20 minutes, approximately 2 to approximately 15 minutes, or approximately 2 to approximately 10 minutes. The conditioning composition and hair may be massaged or otherwise treated to ensure that the conditioning composition makes contact with the majority of the hair.

[0219] At the end of the second time period, the conditioning composition is rinsed off the hair. After rinsing off the conditioning composition, the hair is conditioned and strengthened. The hair also exhibits improved curl retention, reduced frizz, and is less prone to frizz. This method (procedure) can prevent, reduce, or repair damage to hair caused by oxidative bleaching or dyeing processes.

[0220] In various embodiments, the above-described method (pretreatment procedure) strengthens hair, improves curl retention, prevents frizz, and / or repairs damage to hair caused by oxidative bleaching or dyeing to a greater extent than if the method (pretreatment procedure) were performed without pretreating the hair with a strengthening composition prior to oxidative bleaching or dyeing.

[0221] In various embodiments, the above-described method (pretreatment procedure) strengthens hair, improves curl retention, prevents frizz, and / or repairs damage to hair caused by oxidative bleaching or dyeing to a greater extent than when the method (pretreatment procedure) is performed using a contrasting strengthening composition lacking (i)(a) citric acid, its salts, or combinations thereof, but otherwise identical to the strengthening compositions of this disclosure.

[0222] In various embodiments, the above-described method (pretreatment procedure) improves curl retention, prevents frizz, and / or repairs damage to hair caused by oxidative bleaching or dyeing to a greater extent than when the method (pretreatment procedure) is performed using a comparative strengthening composition lacking (i)(b) cyclodextrin, its salt, or combinations thereof, but otherwise identical to the strengthening compositions of this disclosure.

[0223] In various embodiments, the above-described method (pretreatment procedure) strengthens hair, improves curl retention, prevents frizz, and / or repairs damage to hair caused by oxidative bleaching or dyeing to a greater extent than when the method is performed using a comparative strengthening composition lacking (i)(a) citric acid, its salts, or combinations thereof, but otherwise identical to the strengthening composition; and strengthens hair, improves curl retention, prevents frizz, and / or repairs damage to hair caused by oxidative bleaching or dyeing to a greater extent than when the method is performed using a comparative strengthening composition lacking (i)(b) cyclodextrin, its salts, or combinations thereof, but otherwise identical to the strengthening composition of this disclosure.

[0224] II. Post-processing procedures

[0225] According to the so-called "post-treatment procedure," the strengthening composition is not applied to hair that has been oxidatively bleached or dyed before the hair has been oxidatively bleached or dyed. Unlike the pre-treatment procedure discussed above, in the post-treatment procedure, the strengthening composition is not applied to the hair until after the hair has been oxidatively bleached or dyed with the oxidative bleaching or dyeing composition.

[0226] Oxidative bleaching or dyeing compositions can be applied to wet, semi-dry, or dry hair. However, in some embodiments, the hair is first cleaned with shampoo before applying the oxidative bleaching or dyeing composition. After rinsing off the shampoo, the hair will be wet or semi-dry. The oxidative bleaching or dyeing composition is then applied to the wet or semi-dry hair and allowed to remain on the hair for a certain period of time. For example, the oxidative bleaching or dyeing composition can be applied immediately after rinsing off the shampoo, or within approximately 1 hour, 45 minutes, 30 minutes, 15 minutes, 10 minutes, 8 minutes, or 5 minutes after rinsing off the shampoo.

[0227] The bleaching or dyeing composition is left on the hair as needed to ensure an acceptable level of bleaching or dyeing is achieved. For example, the oxidative bleaching or dyeing composition may remain on the hair for approximately 5 minutes to approximately 2 hours, approximately 5 minutes to approximately 1.5 hours, approximately 5 minutes to approximately 1 hour, approximately 5 minutes to approximately 45 minutes, approximately 10 minutes to approximately 2 hours, approximately 10 minutes to approximately 1.5 hours, approximately 10 minutes to approximately 1 hour, or approximately 10 minutes to approximately 45 minutes. The time the oxidative bleaching or dyeing composition remains on the hair sufficient to achieve the desired level of bleaching or dyeing will vary depending on the amount of oxidative bleaching or dyeing composition, the desired level of bleaching or dyeing, the original color of the hair, the hair's tolerance to oxidative bleaching and dyeing, etc. When the oxidative bleaching or dyeing procedure is complete, the hair is cleaned and rinsed. The oxidative bleaching or dyeing composition may initially be rinsed off the hair to remove most of the oxidative bleaching or dyeing composition, and further cleaned with shampoo, and then rinsed off the shampoo. In any case, after washing your hair with shampoo and rinsing the shampoo off, apply the first agent strengthening composition to your hair.

[0228] The strengthening composition is first applied to the hair and allowed to remain on the hair for an initial period of time, the duration of which varies. However, in some embodiments, the first strengthening composition remains on the hair for approximately 1 minute to approximately 1 hour. In further embodiments, the first strengthening composition is left on the hair for periods of approximately 1 to approximately 45 minutes, approximately 1 to approximately 30 minutes, approximately 1 to approximately 20 minutes, approximately 1 to approximately 15 minutes, approximately 1 to approximately 10 minutes, approximately 2 minutes to approximately 1 hour, approximately 2 to approximately 45 minutes, approximately 2 to approximately 30 minutes, approximately 2 to approximately 20 minutes, approximately 2 to approximately 15 minutes, or approximately 2 to approximately 10 minutes. The first strengthening composition and hair may be massaged or otherwise treated to ensure that the first strengthening composition makes contact with the majority of the hair.

[0229] At the end of the first time period, the first strengthening composition is not rinsed off the hair. The hair is then cleaned with shampoo without rinsing off the first strengthening composition. The shampoo can be applied directly to the hair on which the strengthening composition has been applied, i.e., the shampoo can be layered on top of the strengthening composition on the hair. Alternatively, the hair can be rinsed before applying the shampoo. Regardless, after rinsing off the shampoo, the hair is treated with the second strengthening composition for a second time period, which can vary in length. Nevertheless, in some embodiments, the second strengthening composition remains on the hair for approximately 1 minute to 1 hour. In further embodiments, the second strengthening composition remains on the hair for approximately 1 to approximately 45 minutes, approximately 1 to approximately 30 minutes, approximately 1 to approximately 20 minutes, approximately 1 to approximately 15 minutes, approximately 1 to approximately 10 minutes, approximately 2 minutes to approximately 1 hour, approximately 2 to approximately 45 minutes, approximately 2 to approximately 30 minutes, approximately 2 to approximately 20 minutes, approximately 2 to approximately 15 minutes, or approximately 2 to approximately 10 minutes. The second-agent strengthening composition and hair can be massaged or otherwise treated to ensure that the second-agent strengthening composition comes into contact with most of the hair.

[0230] At the end of the second time period, the second strengthening composition is not rinsed off the hair. Without rinsing off the second strengthening composition, the conditioning composition is applied to the hair and allowed to remain on the hair for a third time period, which may vary in length. Nevertheless, in some embodiments, the conditioning composition remains on the hair for approximately 1 minute to approximately 1 hour. In further embodiments, the conditioning composition remains on the hair for approximately 1 to approximately 45 minutes, approximately 1 to approximately 30 minutes, approximately 1 to approximately 20 minutes, approximately 1 to approximately 15 minutes, approximately 1 to approximately 10 minutes, approximately 2 minutes to approximately 1 hour, approximately 2 to approximately 45 minutes, approximately 2 to approximately 30 minutes, approximately 2 to approximately 20 minutes, approximately 2 to approximately 15 minutes, or approximately 2 to approximately 10 minutes. The conditioning composition and hair may be massaged or treated in other ways to ensure that the conditioning composition comes into contact with most of the hair.

[0231] At the end of the third time period, the conditioning composition is rinsed off the hair. After rinsing off the conditioning composition, the hair is conditioned and strengthened. The hair also exhibits improved curl retention, reduced frizz, and is less prone to frizz. This method (procedure) can prevent, reduce, or repair damage to the hair caused by oxidative bleaching or dyeing processes.

[0232] In various embodiments, the above-described method (post-treatment procedure) is able to strengthen hair to a greater extent, improve curl retention, prevent frizz, and / or repair damage to hair caused by oxidative bleaching or dyeing, compared to performing the method (post-treatment procedure) without pre-treating hair with a strengthening composition before oxidative bleaching or dyeing.

[0233] In various embodiments, the above-described method (post-treatment procedure) is able to strengthen hair to a greater extent, improve curl retention, prevent frizz, and / or repair damage to hair caused by oxidative bleaching or dyeing, compared to performing the method (post-treatment procedure) with a contrast strengthening composition that lacks (i)(a) citric acid, its salts or combinations thereof but is otherwise identical to the strengthening composition of this disclosure.

[0234] In various embodiments, the above-described method (post-processing procedure) is able to improve curl retention, prevent frizz, and / or repair damage to hair caused by oxidative bleaching or dyeing to a greater extent compared to performing the method (post-processing procedure) with a contrasting strengthening composition that lacks (i)(b) cyclodextrin, its salt, or a combination thereof but is otherwise identical to the strengthening composition of this disclosure.

[0235] In various embodiments, the above-described method (post-treatment procedure) is able to strengthen hair to a greater extent, improve curl retention, prevent frizz, and / or repair damage to hair caused by oxidative bleaching or dyeing, compared to performing the method with a comparative strengthening composition that lacks (i)(a) citric acid, its salts, or combinations thereof but is otherwise identical to the strengthening composition of this disclosure; and the above-described method (post-treatment procedure) is able to strengthen hair to a greater extent, improve curl retention, prevent frizz, and / or repair damage to hair caused by oxidative bleaching or dyeing, compared to performing the method with a comparative strengthening composition that lacks (i)(b) cyclodextrin, its salts, or combinations thereof but is otherwise identical to the strengthening composition of this disclosure.

[0236] III. Treatment procedures for white or dyed hair

[0237] Strengthening and conditioning compositions are suitable for treating hair that has undergone oxidative bleaching or coloring. For example, the hair may be treated at least one day, at least one week, or at least one month after oxidative bleaching or coloring. The methods repair damage to the hair caused by previous chemical bleaching or coloring. Consumers can perform these treatments at home long after their hair has been oxidatively bleached or colored.

[0238] Oxidative bleaching or dyeing treatments are popular with consumers due to their long-lasting effects. However, extreme or repeated oxidative bleaching or dyeing of hair can damage the hair and weaken the hair fibers. Damaged hair becomes dry, brittle, and more prone to frizz. The methods and compositions disclosed herein address the damage and drawbacks associated with oxidative bleaching and dyeing of hair.

[0239] As described herein, treating oxidatively bleached or dyed hair resulted in surprisingly strong hair, with statistically significant strengthening effects. This was manifested in the higher elastic modulus and higher breaking stress of hair treated according to the method of this disclosure. The improvement in hair strength was also confirmed by differential scanning calorimetry, which showed that hair treated according to this disclosure had a higher denaturation temperature. The method includes first treating the hair with a strengthening composition. After treatment with the strengthening composition, while the strengthening composition is still on the hair, the hair is treated with a conditioning composition. The conditioning composition is applied directly to the hair on which the strengthening composition has been applied, without rinsing off the strengthening composition before applying the conditioning composition. In other words, the conditioning composition is applied over the strengthening composition present on the hair.

[0240] These programs include: (i) Applying a strengthening composition to oxidatively bleached or dyed hair and leaving the strengthening composition on the hair for a first time period, the strengthening composition comprising: (a) Citric acid, its salts, or combinations thereof; (b) Cyclodextrins, their derivatives, or combinations thereof; The total amount of (a) and (b) is approximately 2 to approximately 15 wt.%.

[0241] (c) One or more polyols having 2 to 10 carbon atoms; and

[0242] (d) Water; Wherein, all weight percentages in (i) are based on the total weight of the reinforced composition; (ii) At the end of the first time period, without rinsing the strengthening composition off the hair, the conditioning composition is applied to the hair and allowed to remain on the hair for a second time period, the conditioning composition comprising: (a) One or more cationic surfactants; (b) One or more non-silicone-based fatty compounds; (c) One or more silicone oils; and (d) Water; and (iii) Rinse the strengthening and conditioning compositions off the hair.

[0243] After applying the conditioning composition, leave it on the hair for a second period of time (this is applied over the strengthening composition already applied to the hair). While the second period of time can vary, the conditioning composition typically remains on the hair for approximately 1 minute to 30 minutes. After the second period of time, rinse the conditioning composition off the hair. The rinsed hair is now strengthened and conditioned.

[0244] The method disclosed herein aims to first treat the hair with a strengthening composition, which can be considered a pretreatment step (the strengthening composition can also be considered a pretreatment composition). After treating the hair with the strengthening composition, the hair is subsequently treated with a conditioning composition. The conditioning composition is applied directly to the hair on which the strengthening composition has been applied. In other words, the conditioning composition is applied over the strengthening composition present on the hair, i.e., the strengthening composition is not rinsed off the hair before treating the hair with the conditioning composition.

[0245] The methods described in this disclosure may also include a step of oxidative bleaching or dyeing the hair prior to applying the strengthening composition. For example, in some embodiments, the hair may be oxidatively bleached or dyed on the same day the strengthening composition is applied. The oxidative bleaching or dyeing composition used to oxidatively bleach or dye the hair is typically rinsed off the hair before applying the strengthening composition. For example, the oxidative bleaching or dyeing composition is rinsed off the hair, and optionally, a cleansing process (e.g., using a shampoo composition and rinsing it off) may be performed before applying the strengthening composition. The hair may be oxidatively bleached or dyed and treated with the strengthening and conditioning compositions on the same day. The strengthening and conditioning compositions may be applied, for example, within about 24 hours, 12 hours, 6 hours, 2 hours, or 1 hour after rinsing off the oxidative bleaching or dyeing composition. In other embodiments, the hair is not oxidatively bleached or dyed on the same day it is treated with the strengthening and conditioning compositions. In this case, the hair may have been peroxidized bleached or dyed one day or more before receiving the strengthening and conditioning compositions; or it may have been peroxidized bleached or dyed one week or more before receiving the strengthening and conditioning compositions.

[0246] In various embodiments, the hair has undergone multiple oxidative bleaching or dyeing treatments (e.g., two or more, three or more, four or more, etc.) prior to treatment with the strengthening and conditioning compositions. In particular, the oxidatively bleached or dyed hair may be suffering from damage caused by one or more oxidative bleaching or dyeing treatments. Such damaged hair may exhibit dryness, brittleness, dullness, breakage, split ends, frizz or extreme frizziness, fibrous weakness, or a combination thereof.

[0247] Oxidatively bleached or dyed hair may optionally be cleaned before treatment with the strengthening composition. Apply the shampoo composition to the hair, typically spreading or massaging it into the entire hair, and then rinse it off. If the strengthening composition is applied immediately after cleansing, the hair will already be damp or semi-dry due to rinsing off the shampoo. However, the strengthening composition can be applied to the hair regardless of whether it is damp, semi-dry, or dry. Hair may be dry if it is not cleaned before applying the strengthening composition.

[0248] Apply the strengthening composition to the hair and spread it evenly or massage it into the entire hair. After applying the strengthening composition, allow it to remain on the hair for an initial period of time. This initial period of time can be approximately 1 minute to approximately 1 hour, approximately 1 minute to approximately 45 minutes, approximately 1 minute to approximately 30 minutes, approximately 1 minute to approximately 20 minutes, approximately 1 minute to approximately 15 minutes, approximately 1 minute to approximately 10 minutes, approximately 2 minutes to approximately 1 hour, approximately 2 minutes to approximately 45 minutes, approximately 2 minutes to approximately 30 minutes, approximately 2 minutes to approximately 20 minutes, approximately 2 minutes to approximately 15 minutes, approximately 2 minutes to approximately 10 minutes, approximately 3 minutes to approximately 8 minutes, or approximately 5 minutes.

[0249] Strengthening compositions are typically not rinsed off the hair before applying a conditioning composition. However, in various embodiments, the strengthening composition may be rinsed off the hair before applying the conditioning composition. Nevertheless, between applying the strengthening composition and the conditioning composition, the hair is typically not cleaned with, for example, a shampoo.

[0250] At the end of the first time period, the conditioning composition is applied to the hair, preferably without rinsing the strengthening composition off the hair first, and then spread evenly or massaged into the entire hair. After applying the conditioning composition, it is generally allowed to remain on the hair for a second time period. The second time period can be about 1 minute to about 1 hour, about 1 minute to about 45 minutes, about 1 minute to about 30 minutes, about 1 minute to about 20 minutes, about 1 minute to about 15 minutes, about 1 minute to about 10 minutes, about 2 minutes to about 1 hour, about 2 minutes to about 45 minutes, about 2 minutes to about 30 minutes, about 2 minutes to about 20 minutes, about 2 minutes to about 15 minutes, about 2 minutes to about 10 minutes, about 3 minutes to about 8 minutes, or about 5 minutes.

[0251] After allowing the conditioning composition to remain on the hair for the stated time period, rinse the strengthening composition and conditioning composition off the hair.

[0252] After rinsing off the strengthening and conditioning compositions from the hair, the hair can be dried. The hair can air dry or be dried using a drying device (such as a hairdryer). Similarly, after rinsing off the conditioning compositions from the hair, the hair can be styled. Styling can be done before or after drying.

[0253] In various embodiments, the methods described in this disclosure are able to strengthen hair, improve hair curl retention, prevent hair frizz, and / or repair damage to hair caused by oxidative bleaching or dyeing to a greater extent than when the method is performed without the use of a strengthening composition.

[0254] In various embodiments, the methods described in this disclosure are able to strengthen hair, improve hair curl retention, prevent hair frizz, and / or repair damage to hair caused by oxidative bleaching or dyeing to a greater extent than when the method is performed using a comparative strengthening composition lacking (i)(a) citric acid, its salts, or combinations thereof, but otherwise identical to the strengthening compositions of this disclosure.

[0255] In various embodiments, the methods described in this disclosure are able to strengthen hair, improve hair curl retention, prevent hair frizz, and / or repair damage to hair caused by oxidative bleaching or dyeing to a greater extent than when the method is performed using a comparative strengthening composition lacking (i)(b) cyclodextrin, its salts, or combinations thereof, but otherwise identical to the strengthening compositions of this disclosure.

[0256] In various embodiments, the methods described in this disclosure are able to strengthen hair, improve hair curl retention, prevent hair frizz, and / or repair hair damage caused by oxidative bleaching or dyeing to a greater extent than when performed using a comparative strengthening composition lacking (i)(a) citric acid, its salts, or combinations thereof, but otherwise identical to the strengthening composition of this disclosure; and the methods described in this disclosure are able to strengthen hair, improve hair curl retention, prevent hair frizz, and / or repair hair damage caused by oxidative bleaching or dyeing to a greater extent than when performed using a comparative strengthening composition lacking (i)(b) cyclodextrin, its salts, or combinations thereof, but otherwise identical to the strengthening composition of this disclosure.

For example, in some embodiments, the hair may be oxidatively bleached or dyed on the same day the strengthening composition is applied. The oxidative bleaching or dyeing composition used for oxidative bleaching or dyeing the hair is typically rinsed off the hair before applying the strengthening composition. For example, the oxidative bleaching or dyeing composition is rinsed off the hair before applying the strengthening composition, and optionally, a cleansing process may be performed (e.g., using a shampoo composition and rinsing it off). The hair may be oxidatively bleached or dyed and treated with the strengthening and conditioning compositions on the same day. The strengthening and conditioning compositions may be applied, for example, within about 24 hours, 12 hours, 6 hours, 2 hours, or 1 hour after rinsing off the oxidative bleaching or dyeing composition. In other embodiments, the hair is not oxidatively bleached or dyed on the same day it is treated with the strengthening and conditioning compositions. In this case, the hair may have undergone oxidative bleaching or dyeing one day or more before receiving the strengthening and conditioning compositions; or it may have undergone oxidative bleaching or dyeing one week or more before receiving the strengthening and conditioning compositions. In various embodiments, the hair has undergone multiple oxidative bleaching or dyeing processes prior to receiving the strengthening and conditioning compositions.

[0272] After rinsing the conditioning product off your hair, you can dry it. Hair can air dry or be dried using a hairdryer, etc. Similarly, after rinsing the conditioning product off your hair, you can style it. Styling can be done before or after drying.

[0273] In addition to methods for treating oxidatively bleached or dyed hair, this disclosure also aims to relate to compositions used in these methods, particularly strengthening compositions.

[0291] Example 3

[0292] (Pretreatment with a reinforcing composition)

[0293] Tests were conducted to investigate how the compositions and methods described throughout this disclosure affect the integrity of oxidatively bleached or dyed hair. Caucasian hair strands (2 gm), curl pattern 4 (CP4), were cleaned with standard shampoo prior to treatment. The bleaching composition was prepared as follows: commercially available bleaching powder (9% hydrogen peroxide) and color developer (30 Volume) were mixed in a 1:1.5 ratio (bleaching powder: color developer (1:1.5)), and the ingredients listed below were added.

[0294]

[0295] After cleaning the hair strands, proceed with one of the following steps: Control group: Hair strands were oxidatively bleached. A bleaching composition was prepared by mixing standard bleaching powder and developer (30 V) in a 1:1.5 ratio (bleaching powder: developer (1:1.5)). 10 grams of the bleaching composition was applied to each hair strand. The bleaching composition was left on the hair for 50 minutes. After 50 minutes, the bleaching composition was rinsed off the hair, and the hair was cleaned again with standard shampoo. Bleached hair strands that did not undergo any additional treatment served as the control group.

[0296] Comparative Example 1: The hair strands were treated in the same way as the control group described above. However, after cleaning the bleached hair with standard shampoo (and rinsing off the shampoo), the conditioning composition of Example 2 was immediately applied to wet or semi-dry hair and allowed to remain on the hair for 5 minutes. After 5 minutes, the conditioning composition was rinsed off the hair.

[0297] Example A: Before oxidative bleaching, the hair strands were pretreated with the strengthening composition A of the present invention from Example 1. The strengthening composition A of the present invention 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 immediately bleached as described for the control group. After cleaning the bleached hair with standard shampoo (and rinsing off the shampoo), the conditioning composition from Example 2 was immediately applied to wet or semi-dry hair and allowed to remain on the hair for 5 minutes. After 5 minutes, the conditioning composition was rinsed off the hair.

[0298] Example B of the Invention: Before oxidative bleaching of the hair, the hair strands were pretreated with the strengthening composition B of the present invention from Example 1. The strengthening composition B of the present invention 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 immediately bleached as described in the control group. After cleaning the bleached hair with standard shampoo (and rinsing off the shampoo), the conditioning composition of Example 2 was immediately applied to damp or semi-dry hair and allowed to remain on the hair for 5 minutes. After 5 minutes, the conditioning composition was rinsed off the hair.

[0299] Example C: Before oxidative bleaching the hair, the hair strands were pretreated with the strengthening composition B of the present invention from Example 1. The strengthening composition B of the present invention 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 immediately bleached as described in the control group. After cleaning the bleached hair with standard shampoo (and rinsing off the shampoo), the conditioning composition of Example 2 was immediately applied to damp or semi-dry hair and allowed to remain on the hair for 5 minutes. After 5 minutes, the conditioning composition was rinsed off the hair.

[0300] Hair treated according to the above protocol was analyzed by micro-tensile testing (Young's modulus and fracture stress) and differential scanning calorimetry (thermal integrity). One-way ANOVA was performed using SPSS software at 95% confidence intervals to analyze significant differences between DSC and MTT outputs. Hair frizz was also assessed.

[0301] Elastic modulus and fracture stress

[0302] Hair was analyzed using a miniature tensile tester (MTT-675, Dia-Stron Ltd). The MTT was used to measure Young's modulus, the slope of the initial portion of a stress-strain curve adjusted for cross-sectional area, representing a measure of the spring-like structure of hair. It also measured the breaking stress, the total force required to break a hair fiber. The test results were statistically analyzed using IBM SPSS software with a Tukey-Kramer post-hoc test (k=3) to identify and exclude significant outliers. Statistical significance was analyzed using SPSS software at a 95% confidence level. The results are shown in the table below and corresponding figures. The elastic modulus represents the elastic properties of the fiber. A higher value indicates greater elasticity, suggesting less brittleness of the hair due to reinforcement and a lack of dryness and damage.

[0303]

[0304] The statistical significance of the elastic modulus is as follows: IB > IA = IC > Control = C-1. The statistical significance of the fracture stress is as follows: IB > IA = IC > Control = C-1. The data show that the performance of procedure B of the present invention is superior to that of procedures A and C of the present invention; and the performance of procedures A and C of the present invention is superior to that of the control group and the procedure of Comparative Example 1.

[0305] Thermal integrity / protein crosslink density

[0306] Hair was analyzed using differential scanning calorimetry (DSC, DSC-2500, TA Instruments). DSC measures denaturation temperature, a measure of the thermal stability of proteins in hair and an indication of protein cross-linking density. Higher values ​​represent higher thermal integrity, an indication of more cross-links (stronger hair).

[0307]

[0308] The statistical significance of crosslinking density is as follows: IA = IC > IB > C-1 > Control group. The performance of the invented procedures IA and IC is better than that of the invented procedure IB; and the performance of the invented procedure IB is better than that of the control procedure C-1, while the performance of C-1 is better than that of the control.

[0309] Frizz Test

[0310] The samples, processed according to the protocol 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. A photograph of the hair strand is shown below. Figure 1 As shown. The results indicate that hair pretreated with the strengthening composition of Example 1 suffered less frizz and retained its shape and curl better.

[0311] Example 6

[0312] (Post-treatment using a reinforcing composition)

[0313] Tests were conducted to investigate how the compositions and methods described throughout this disclosure affect the integrity of oxidatively bleached or dyed hair. Caucasian hair strands (2 gm), curl pattern 4 (CP4), were cleaned with standard shampoo prior to treatment. The bleaching composition was prepared as follows: commercially available bleaching powder (9% hydrogen peroxide) and color developer (30 Volume) were mixed in a 1:1.5 ratio (bleaching powder: color developer (1:1.5)), and the ingredients listed below were added.

[0314] After cleaning the hair strands, proceed with one of the following steps: Control group: Hair strands were oxidatively bleached. A bleaching composition was prepared by mixing standard bleaching powder and developer (30 V) in a 1:1.5 ratio (bleaching powder: developer (1:1.5)). 10 grams of the hair bleaching composition was 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 off the hair, and the hair was cleaned with shampoo. Bleached hair strands that did not undergo any additional treatment served as the control group.

[0315] Comparative Example 1: The hair strands were treated as described in the control group above. However, immediately after shampooing the bleached hair (and rinsing off the shampoo), the conditioning composition of Example 2 was applied to wet or semi-dry hair and allowed to remain on the hair for 5 minutes. After 5 minutes, the conditioning composition was rinsed off the hair.

[0316] Example A: The hair strands were bleached as described in the control group above. However, after cleaning the bleached hair with shampoo (and rinsing off the shampoo), the strengthening composition A according to the invention 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 cleaned with standard shampoo and the shampoo was rinsed off the hair. Immediately after rinsing off the shampoo, the strengthening composition A according to the invention was applied again (a second time) 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, immediately without rinsing off the strengthening composition A according to the invention, the hair care composition of Example 2 was applied to the hair, left on the hair for 5 minutes, and then rinsed off the hair.

[0317] Example B: The hair strands were bleached as described in the control group above. However, after cleaning the bleached hair with shampoo (and rinsing off the shampoo), the strengthening composition B of the present invention from 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. After the additional 5 minutes, the hair strands were immediately cleaned with standard shampoo, and the shampoo was rinsed off the hair. After rinsing off the shampoo, the strengthening composition B of the present invention was immediately applied to the hair strands again (a second time) (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 conditioning composition of Example 2 was immediately applied to the hair without rinsing off the strengthening composition B of the present invention, left on the hair for 5 minutes, and then rinsed off the hair.

[0318] Example C: The hair strands were bleached as described in the control group above. However, after cleaning the bleached hair with shampoo (and rinsing off the shampoo), the strengthening composition C of the present invention from 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. After the additional 5 minutes, the hair strands were immediately cleaned with standard shampoo and the shampoo was rinsed off the hair. After rinsing off the shampoo, the strengthening composition C of the present invention was immediately applied to the hair strands again (a second time) (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 conditioning composition of Example 2 was immediately applied to the hair without rinsing off the strengthening composition C of the present invention, left on the hair for 5 minutes, and then rinsed off the hair.

[0319] Hair treated according to the above protocol was analyzed by micro-tensile testing (elastic modulus and breaking stress) and differential scanning calorimetry (thermal integrity). One-way ANOVA was used to determine statistical significance between the control composition and the composition of the present invention at a 95% confidence level. Hair frizz was also assessed.

[0320] Elastic modulus and fracture stress

[0321] Hair was analyzed using a micro tensile tester (Mini Tensile Tester, MTT-675, Dia-Stron Ltd). The MTT was used to measure the modulus of elasticity. Breaking stress, i.e., the total force required to break a hair fiber, was also measured. The test results were statistically analyzed using IBM SPSS statistical analysis software with a Tukey-Kramer post-hoc test. One-way ANOVA was used to determine statistical significance between the control group and the composition of the present invention. The results are shown in the table below and the corresponding figures. The modulus of elasticity represents elasticity. A higher value indicates greater elasticity, suggesting less hair brittleness due to reinforcement and lack of dryness and damage.

[0322]

[0323] The statistical significance of the elastic modulus is as follows: IB > IA = IC > Control = C-1. The statistical significance of the fracture stress is as follows: IB > IA = IC > Control = C-1. Therefore, the performance of the inventive procedure B is superior to that of the inventive procedures IA and IC; and the performance of the inventive procedures IA and IC is superior to that of the control group.

[0324] Hair was analyzed using differential scanning calorimetry (DSC, DSC-2500, TA Instruments). DSC measures denaturation temperature, a measure of the thermal stability of proteins in hair and an indication of cross-link density. Higher values ​​represent higher thermal integrity, indicating more cross-links formed with hair bonds (stronger hair).

[0325]

[0326] The statistical significance of crosslinking density is as follows: IA > IB = IC > C-1 > Control Group. Therefore, the performance of the inventive procedure IA is superior to that of the inventive procedures IB and IC; and the performance of the inventive procedures IB and IC is superior to that of Comparative Procedure 1, which in turn is superior to that of the control.

[0327] Frizz Test

[0328] Samples treated according to the protocol 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. A photograph of the hair strand is shown below. Figure 2 As shown. The results indicate that hair pretreated with the strengthening composition of Example 1 suffered less frizz and retained its shape and curl better.

[0329] Example 3

[0330] Tests were conducted to investigate how the compositions and methods described throughout this disclosure could benefit oxidatively bleached or dyed hair. Machine-bleached Caucasian hair strands (2 gm), curl pattern 4 (CP4), were cleaned with standard shampoo prior to treatment. All machine-bleached hair strands were cleaned with standard shampoo prior to further testing. One cleaned hair strand served as a control. Another cleaned hair strand was treated with one of the strengthening compositions from Example 1. Each strengthening composition from Example 1 was applied to the hair strand (0.4 g per gram of hair), massaged into the hair strand for 1 minute, and left on for an additional 5 minutes. Next, the conditioning composition from Example 2 was applied to the hair that had been treated with the strengthening composition, i.e., the conditioning composition was layered on top of the strengthening composition, and left on the hair strand for 5 minutes. After 5 minutes, both the strengthening composition and the conditioning composition were rinsed off the hair. The hair was analyzed using a Miniature Tensile Tester (MTT) and Differential Scanning Calorimetry (DSC). One-way ANOVA was used to determine statistical significance among controls, comparatives, and the invention procedure. A visual assessment of hair frizz was also performed.

[0331] Elastic modulus and fracture stress

[0332] Hair was analyzed using a micro tensile tester (Miniature Tensile Tester, MTT-675, Dia-Stron Ltd). The MTT was used to measure the modulus of elasticity, which is the slope of the initial portion of a strain-stress curve adjusted for cross-sectional area, representing a measure of the spring-like structure of hair. It can also measure the breaking stress, which is the total force required to break a hair fiber. One-way ANOVA was used to determine statistical significance among controls, comparatives, and inventive procedures. The results are shown in the table below and Figure 3 In traditional Chinese medicine, the modulus of elasticity represents the elastic properties of hair fibers. A higher value indicates greater elasticity, suggesting that the hair is less brittle due to strengthening and a lack of dryness and damage. A higher value for breaking stress indicates that the hair fibers are stronger, suggesting that the hair has been strengthened and is free from damage.

[0333]

[0334] As shown above, the elastic modulus value increased significantly. Procedures A and C provided higher values ​​than the control. Procedure B provided higher values ​​than the control, procedures A, and C. The fracture stress value also increased significantly because procedure B provided a larger value than the control, procedures A, and C. Procedures A and C were the same as the control. Overall, compared with the control and A and B, B had a significantly higher elastic modulus and fracture stress.

[0335] Crosslinking density

[0336] Hair was analyzed using differential scanning calorimetry (DSC, DSC-2500, TA Instruments). DSC measures denaturation temperature, a measure of the thermal stability of proteins in hair and an indication of protein cross-linking density. Higher values ​​represent higher thermal integrity, an indication of more cross-links (stronger hair).

[0337]

[0338] Denaturation temperature (Td) represents the cross-linking density of keratin (fibers). Compositions A and B showed a statistically significant increase in denaturation temperature compared to the control. Composition C exhibited an even higher denaturation temperature, which was statistically significant compared to A and B, and also compared to the control.

[0339] Frizz Test

[0340] The hair strand was placed in a humidity chamber at 25°C and 80% relative humidity for 4 hours. After 4 hours, the sample was removed from the humidity chamber and visually analyzed. A photograph of the hair strand is shown. Figure 3 The results showed that hair treated according to the method of this disclosure suffered less frizz and maintained better shape and curl.

[0341] The foregoing description elucidates and describes 99 aspects of this disclosure. Furthermore, this disclosure only shows and describes preferred embodiments. However, as stated above, it should be understood that it can be used in various other combinations, modifications, and environments, and can be changed or modified within the scope of the inventive concept described herein, commensurate with the foregoing teachings and / or the skill or knowledge in the relevant technical field. The embodiments described herein are intended to further explain the best mode known to the applicant and to enable those skilled in the art to utilize this disclosure in such or other embodiments, with various modifications required according to the specific application or use. Therefore, this description is not intended to limit the invention to the forms disclosed herein. Furthermore, the appended claims are intended to be interpreted as including alternative embodiments. Therefore, this specification is not intended to limit the invention to the forms disclosed herein. Furthermore, the appended claims are intended to be interpreted as including alternative embodiments.

[0342] As used herein, the terms “comprising,” “having,” and “including” are used in their open, non-restrictive sense.

[0343] The terms “a”, “an”, and “the” are understood to cover both plural and singular forms.

[0344] The term "mixtures thereof" also refers to "various mixtures thereof." Throughout this disclosure, the term "mixtures thereof" is used after a series of elements, as shown in the example below, where the letters AF represent the elements: "one or more elements selected from A, B, C, D, E, F and mixtures thereof." The term "mixtures thereof" does not require that the mixture contain all elements of A, B, C, D, E, and F (although it may contain all elements of A, B, C, D, E, and F). Rather, it indicates a mixture that may contain any two or more elements from A, B, C, D, E, and F. In other words, it is equivalent to the phrase "one or more elements selected from A, B, C, D, E, F and mixtures containing any two or more elements from A, B, C, D, E, and F."

[0345] Similarly, the term "its salt" also refers to "its various salts." Therefore, when this disclosure refers to "elements selected from A, B, C, D, E, F, their salts, and mixtures thereof," it means that it may include one or more of A, B, C, D, and F; it may include one or more of salts of A, B, C, D, E, and F; or it may include mixtures of any two of A, B, C, D, E, F, and salts of A, B, C, D, E, and F. Salts mentioned throughout this disclosure may be salts having counterions, such as alkali metal, alkaline earth metal, or ammonium counterions. However, this list of counterions is not limiting. Counterions suitable for the components described herein are known in the art.

[0346] The expression "one or more" means "at least one", and therefore includes both single components and mixtures / combinations.

[0347] The term "multiple" means "more than one" or "two or more".

[0348] Unless otherwise stated in the operational examples, all numerical values ​​representing the quantity of components and / or reaction conditions may be modified in all cases by the term "about," meaning within + / - 5% of the values ​​shown.

[0349] Unless otherwise stated, all percentages, parts and proportions herein are based on the total weight of the compositions of the invention.

[0350] Some of the identified components may overlap. In cases where overlap is possible and the composition comprises two components (or more than two overlapping components), the overlapping compound does not represent more than one component. For example, some compounds may be considered both nonionic surfactants or emulsifiers and fatty compounds. If a particular composition comprises both a nonionic surfactant or emulsifier and a fatty compound, then a single compound will function only as a nonionic surfactant or emulsifier, or only as a fatty compound (that single compound will not function simultaneously as both a nonionic surfactant or emulsifier and a fatty component).

[0351] As used herein, all ranges provided are intended to encompass each specific range within a given range, as well as combinations of subranges between these ranges. Thus, the range 1–5 specifically includes 1, 2, 3, 4, and 5, as well as subranges such as 2–5, 3–5, 2–3, 2–4, 1–4, etc. All ranges and values ​​disclosed herein are inclusive and composable. For example, any value or point described herein that falls within the ranges described herein can be used as a minimum or maximum value to derive subranges, etc.

[0352] The compositions of this application may optionally include one or more surfactants and / or emulsifiers other than the nonionic surfactants and emulsifiers described above, such as one or more anionic, cationic and / or amphoteric surfactants.

[0353] The terms “surfactant” and “emulsifier” include salts of these surfactants and emulsifiers, even if not explicitly stated. In other words, whenever this disclosure refers to a surfactant or emulsifier, it is intended to also cover its salts (within the scope of their presence), even if the specification may not specifically mention the salts (or may not mention them in every instance throughout the disclosure), for example, by using expressions such as “its salts” or “its various salts.” Sodium and potassium are common cations that form salts with surfactants and emulsifiers. However, additional cations, such as ammonium ions, or alkanol ammonium ions (e.g., monoethanolammonium ions or triethanolammonium ions), may also form salts of surfactants.

[0354] As used herein, the terms “substantially free” or “essentially free” mean that, based on the total weight of the composition, the weight of the specific substance added to the composition is less than about 2%. Nevertheless, the composition may include less than about 1 wt.%, less than about 0.5 wt.%, less than about 0.1 wt.%, or contain none of the stated specific substance.

[0355] All components affirmatively stated in this disclosure may be negatively excluded from the claims. For example, a claimed composition may be "free of," "substantially free of" (or "essentially free of") one or more components affirmatively stated in this disclosure. Furthermore, components, compounds, or ingredients used to strengthen the composition may be excluded from the conditioning composition, and vice versa.

[0356] All publications and patent applications referenced in this specification are incorporated herein by reference and for any and all purposes as if each individual publication or patent application had been expressly and individually indicated as incorporated by reference. In the event of any inconsistency between this disclosure and any publication or patent application incorporated herein by reference, this disclosure shall prevail.
