Description

Title of the invention: hair straightening processes SCOPE OF DISCLOSURE

[0001] This disclosure relates to hair treatment processes, for example, processes to provide hair with better fiber alignment, frizz control and a smooth texture. CONTEXT

[0002] Many consumers use cosmetic and care compositions that improve the appearance of hair, for example, by changing the color, style, and / or shape of the hair and / or by giving the hair various cosmetic properties, such as shine and revitalization. Hair can become dry or damaged for various reasons, for example, exposure to the elements, poor nutrition, mechanical treatments (e.g., brushing), styling treatments using chemicals, dyeing, heat, diet, etc. Even cleansing products can remove the hair's natural sebum, which dries it out and can give it a dull appearance, split ends, and frizz.

[0003] Chemical hair treatments include bleaching and coloring treatments to change hair color. Chemical treatments also include processes that permanently alter the shape and structure of hair, such as perming, perming, relaxing, or straightening. These chemical treatments change the appearance of hair by altering its physical structure, which inevitably causes some degree of hair damage. 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 treatments have 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 leave hair feeling greasy. Furthermore, the effects are not usually visible after several hours (e.g., 8 hours) of treatment, and multiple treatments are usually required, making the process time-consuming and labor-intensive.

[0005] Hair damage results in split ends, dryness, breakage, and hair that becomes frizzy and difficult to style. Since the visible part of the hair is dead, it lacks the ability to to 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 offer little improvement to the hair. Therefore, hair treatment technologies that can smooth, straighten, or style hair without chemically damaging it are desired.

[0006] There is always a need to offer improved hair styling ease, for example, improved hair alignment, reduced unwanted volume (in particular a reduction in frizz), and increased shine. DISCLOSURE SUMMARY

[0007] This disclosure relates to processes for improving the appearance, feel, and manageability of hair. In particular, the methods improve fiber alignment, reduce frizz, and impart a smooth texture. Treated hair is soft, shiny, revitalized, and has a healthy appearance. The processes form a smooth coating on the hair surface that is remarkably durable. The desirable cosmetic properties imparted to the hair are long-lasting, moisture-resistant, and maintained even after washing.

[0008] The processes of this disclosure typically include:

[0009] (i) the application of a hair treatment composition to the hair, the act of Leave the hair treatment product on the hair for a period of time, then rinse it out; the hair treatment product includes:

[0010] (a) citric acid, one of its salts or one of its combinations;

[0011] (b) of cyclodextrin, one of its salts, or one of its combinations;

[0012] wherein a combined total amount of (a) and (b) is about 2 to about 12% by weight;

[0013] (c) one or more cyclic carbonates; and

[0014] (d) water;

[0015] (ii) after rinsing the hair treatment composition from the hair, the application of a leave-in composition to the hair; the leave-in composition comprising:

[0016] (a) one or more silicones;

[0017] (b) one or more film-forming polymers; and

[0018] (c) water.

[0019] After applying the leave-in formula, the hair can be dried, for example, with a hairdryer or can dry naturally. Subsequently, the hair can be treated with a heat treatment. The heat treatment is typically produced at a temperature of about 150 to about 300 °C. In various embodiments, the heat treatment occurs at a temperature of about 150 to about 280 °C, about 180 to about 300 °C, about 180 to about 280 °C, about 200 to about 300 °C, about 200 to about 280 °C, about 200 to about 260 °C, about 200 to about 250 °C, about 210 to about 300 °C, about 210 to about 280 °C, about 180 °C, about 190 °C, about 200 °C, about 210 °C, about 220 °C, about 230 °C, about 240 °C, about 250 °C or about 260 °C.

[0021] Citric acid and its salts provide a myriad of benefits to hair. For example, it acts as an antioxidant, eliminates buildup and debris from the hair, and improves blood circulation in the scalp, which stimulates hair follicles and promotes hair growth. Its acidic pH is also useful for balancing the scalp's pH, as many hair care products make it more alkaline. The citric acid in these compositions also interacts with cyclodextrin in a unique way and enhances film formation on the hair, which is further potentiated by heat. Sodium citrate (or trisodium citrate) is an example of a citric acid salt.

[0047] The various aspects are not limited to the arrangements, compositions and instrumentation shown in the drawings. DETAILED DESCRIPTION OF THE DISCLOSURE

[0048] This disclosure relates to processes for treating hair, particularly hair requiring reduced frizz and improved softness. This is achieved using a hair treatment composition that includes a unique combination of citric acid, cyclodextrin, and propylene carbonate. The inventors believe that propylene carbonate undergoes a reaction when subjected to heat treatment. The heat activates a reaction with the propylene carbon and amine groups of the hair fibers, presumably forming an N,N'-disubstituted urea bond that contributes to the durable fixation of the newly formed shape. The processes are gentle, long-lasting, and reduce hair frizz while simultaneously improving smoothness. The processes improve fiber alignment, reduce frizz, and impart a smooth texture to a surprising degree.The longevity of the improved fiber alignment, frizz reduction, and smooth texture is also significant and surprising. Hair treated according to the processes described here retains these desirable cosmetic properties, even after multiple washing cycles. Thus, the benefits provided by the formulas are remarkably long-lasting and wash-resistant.

Nevertheless, in various embodiments, the compositions include approximately 0.01 to approximately 10% by weight of one or more non-ionic surfactants or emulsifiers. In other embodiments, the compositions include about 0.01 to about 8% by weight, about 0.01 to about 5% by weight, 0.01 to about 3% by weight, about 0.01 to about 1% by weight, about 0.05 to about 10% by weight, about 0.05 to about 8% by weight, about 0.05 to about 5% by weight, about 0.05 to about 3% by weight, or about 0.05 to about 1% by weight, relative to a total weight of the composition. (i)(i) Miscellaneous ingredients

[0173] Hair treatment compositions optionally include or exclude (or are essentially free from) one or more miscellaneous ingredients. Miscellaneous ingredients are ingredients that are compatible with the hair treatment compositions and that do not disrupt or materially affect the basic and novel properties of the compositions. Non-limiting examples of ingredients include preservatives, perfumes, pH adjusters, salts, chelating agents, buffers, antioxidants, flavonoids, vitamins, botanical extracts, UV filtering agents, proteins, protein hydrolysates and / or isolates, fillers (e.g., organic and / or inorganic fillers such as talc, calcium carbonate, silica, etc.), compositional colorants, etc.In various embodiments, the various ingredients are selected from preservatives, perfumes, pH adjusters, salts, chelating agents, buffers, composition colorants, and mixtures thereof. For the purposes of this disclosure, a "composition colorant" is a compound that colors the composition but does not have a noticeable coloring effect on hair. In other words, the composition colorant is included to give the composition color for aesthetic purposes but is not intended to impart coloring properties to hair. Hair gels, for example, may be found in a variety of different colors (e.g., light blue, light pink, etc.), but applying the hair gel to the hair does not visibly change the hair color.

[0174] The total quantity of one or more miscellaneous ingredients in the hair treatment compositions, if any, will vary. Nevertheless, in various embodiments, the compositions include approximately 0.1 to approximately 15% by weight of one or more miscellaneous ingredients, relative to the total weight of the compositions. In other embodiments, the compositions include approximately 0.1 to approximately 12% by weight, approximately 0.1 to approximately 10% by weight, approximately 0.1 to approximately 5% by weight, approximately 0.5 to approximately 15% by weight, approximately 0.5 to approximately 12% by weight, approximately 0.5 to approximately 10% by weight, approximately 0.5 to approximately 8% by weight, approximately 0.5 to approximately 5% by weight, approximately 1 to approximately 15% by weight, approximately 1 to approximately 12% by weight, approximately 1 to approximately 10% by weight, approximately 1 to approximately 8% by weight, approximately 1 to approximately 5% by weight, approximately 2 to approximately 15% by weight, approximately 2 to approximately 12% by weight, approximately 2 at about 10% by weight, about 2 to about 8% by weight, or about 2 to about 5% by weight, relative to the total weight of the compositions. PH

[0175] The pH of the hair treatment composition may vary. However, in various embodiments, a pH below 7 (an acidic pH) is desirable. For example, the pH may be from about 2.5 to about 6.5, about 2.5 to about 6, about 2.5 to about 5.5, about 2.5 to about 5, about 2.5 to about 4.5, about 3 to about 6.5, about 3 to about 6, about 3 to about 5.5, about 3 to about 5, about 3 to about 4.5, preferably about 3 to about 4.5. Treatment

[0176] The hair treatment composition is applied to the hair and left on the hair for a certain period before rinsing it out. The hair treatment composition can be applied to wet or damp hair, or to dry hair. The hair treatment composition contains a substantial amount of water, and therefore, applying the hair treatment composition to the hair will have a wetting effect. In various embodiments, the hair is cleansed, for example, with shampoo, before applying the hair treatment composition.

[0177] A unique feature of the present processes is the absence of a pretreatment step using a composition containing an alkali-forming agent. The processes in this disclosure do not require treating the hair with an alkali-forming agent before, after, or during the process. Many hair straightening or smoothing processes require treatment with a chemical straightening composition, for example, a hydroxide straightener (or a hydroxide straightening composition). Various straightening and smoothing compositions are known in the art. For example, chemical straightening procedures use a hydroxide straightener in a process called lanthionization, which breaks disulfide bonds and alters the curl pattern of the hair. During this process, the curl pattern is loosened or straightened. The cortex is thus elongated, stretching the original curl pattern, making it a permanent change.There are several types of hydroxide relaxers that contain active ingredients such as sodium hydroxide (NaOH), potassium hydroxide (KOH), and lithium hydroxide (LiOH). Sometimes, calcium (CaOH) is added to hydroxide relaxers, but it is not used solely for hair straightening. Therefore, in various embodiments, the hydroxide-based hair straightening or smoothing composition typically has an alkaline pH, for example, a pH of approximately 8 to 12, or approximately 9 to 12, or approximately 10 to 12.

[0178] The processes of this disclosure are preferably performed on hair that has not recently been treated with an alkali-forming agent. For example, the hair has not recently been treated with a hydroxide relaxer. The hair may never have been treated with an alkaline composition or another smoothing or relaxing composition such as a hydroxide relaxer. Typically, the processes of this disclosure treat hair that has not been treated with an alkali-forming agent (e.g., hydroxide relaxer, etc.) within the previous 24 hours. Preferably, the processes of this disclosure treat hair that has not been treated with an alkali-forming agent (e.g., hydroxide relaxer, etc.) within 2 days or more, 3 days or more, 1 week or more, 1 month or more, 6 months or more, or that has never been treated with an alkali-forming agent.

[0179] Other hair-smoothing or straightening compositions include ingredients such as glyoxylic acid. Glyoxylic acid smooths hair fibers without breaking the cystine disulfide bond. Therefore, it provides long-lasting straightening effects without damaging the hair and scalp, which is more common with alkaline chemicals and other smoothing agents. The carboxyl and aldehyde groups of glyoxylic acid react with the amine groups in hair keratin, resulting in the formation of stable bonds.

[0180] In various embodiments, the processes of this disclosure are performed on hair that has not recently been treated with glyoxylic acid. Typically, the processes of this disclosure treat hair that has not been treated with glyoxylic acid within the previous 24 hours. Preferably, the processes of this disclosure treat hair that has not been treated with glyoxylic acid for 2 days or more, 3 days or more, 1 week or more, 1 month or more, 6 months or more, or that has never been treated with an alkalizing agent (e.g., a hydroxide relaxer). In other embodiments, the hair may have recently been treated with glyoxylic acid.

[0181] The hair treatment composition can remain on the hair for an extended period. However, in various embodiments, the hair treatment composition is applied to the hair and left on the hair for approximately 30 seconds to approximately 60 minutes. In other embodiments, the hair treatment composition remains on the hair for approximately 1 minute to approximately 60 minutes, 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 2 minutes to approximately 60 minutes, approximately 2 minutes to approximately 45 minutes, approximately 2 minutes to approximately 30 minutes, and approximately 2 minutes to approximately 20 minutes. minutes, approximately 2 minutes to approximately 15 minutes, approximately 5 minutes to approximately 60 minutes, approximately 5 minutes to approximately 45 minutes, approximately 5 minutes to approximately 30 minutes, approximately 5 minutes to approximately 20 minutes, approximately 5 minutes to approximately 15 minutes minutes, approximately 5 minutes, approximately 8 minutes, approximately 10 minutes, approximately 12 minutes minutes, or approximately 15 minutes. Once the hair treatment product has been left on the hair for the appropriate time, it is rinsed out with water. Afterward, the leave-in product can be applied to the hair, followed by heat styling. No-rinse formula

[0182] The leave-in formula is typically applied to the hair shortly after rinsing out the hair treatment formula. For example, the leave-in formula may be applied to the hair within 5, 10, 15, 20, 30, 45, or 60 minutes after rinsing out the hair treatment formula. It is not mandatory for the leave-in formula to be applied to the hair immediately after rinsing out the hair treatment formula, but application of the leave-in formula shortly after rinsing out the hair treatment formula is preferred. (ii)(a) Silicones

[0183] Silicones may be called silicone oils. Non-limiting examples of silicones include dimethicone, dimethiconol, cyclomethicone, polysilicone-11, phenyl trimethicone, trimethylsilylamodimethicone, and stearoxytrimethylsilane.

A preferred quaternized or quaternizable polysiloxane is bis-cetearyl amodimethicone.

[0185] In certain embodiments, at least one or more of the silicones is an amino-functionalized silicone. The term "amino-functionalized silicone" is intended to indicate any silicone comprising at least one primary, secondary, or tertiary amine or a quaternary ammonium group without a piperidinyl group. The term "amino-functionalized silicone" is interchangeable with the term "amino silicone." In some cases, amino-functionalized silicones are alkoxylated and / or hydroxylated amino-silicones. Non-limiting examples include amodimethicone, bis-hydroxy / methoxy amodimethicone, bis-cetearyl amodimethicone, amodimethicone, bis(C13-C15 alkoxy) PG amodimethicones, aminopropyl phenyl trimethicones, aminopropyl dimethicones, bis-amino PEG / PPG-41 / 3 aminoethyl PG-propyl dimethicones, caprylyl methicones, and mixtures thereof.

The nonionic polyethers / polyurethanes may have at least one hydrophilic fraction and at least one hydrophobic fraction. More specifically, said polymers may contain in their chain both hydrophilic sequences, most often of a polyoxyethylenated nature, and hydrophobic sequences, which may be aliphatic bonds alone and / or cycloaliphatic and / or aromatic bonds. In various embodiments, these polyether-polyurethanes comprise at least two lipophilic hydrocarbon chains, having from 6 to 30 carbon atoms, preferably from 6 to 20, separated by a hydrophilic sequence, the hydrocarbon chains being either dangling chains or chains at the end of a hydrophilic sequence.In particular, it is possible that one or more dangling chains may be considered. Furthermore, the polymer may include a hydrocarbon chain at one or both ends of a hydrophilic sequence.

[0230] Polyether-polyurethanes can be polyblocks, particularly in triblock form. The hydrophobic sequences can be at each end of the chain (e.g., a tri-sequenced copolymer bearing a hydrophilic central sequence) or distributed both at the ends and throughout the chain (e.g., a poly-sequenced copolymer). These same polymers can also be in the form of graft motifs or can be star-shaped.

[0231] Nonionic polyethers / polyurethanes containing a fatty chain may be tri-sequenced copolymers in which the hydrophilic sequence is a polyoxyethylenated chain comprising 50 to 1000 oxyethylenated groups. Nonionic polyurethane-polyethers comprise a urethane linkage between the hydrophilic sequences, hence the origin of the name. By extension, those whose hydrophilic sequences are linked by other chemical bonds to hydrophobic sequences are also included among the non-ionic polyether-polyurethanes containing a hydrophobic chain.

[0232] Non-limiting examples of nonionic polyethers / polyurethanes containing a hydrophobic chain include Rheolate® 205 containing a urea functional group sold by RHEOX, or alternatively Rheolates® 208, 204, or 212, as well as Acrysol RM 184®.

In such cases, R1 to R5 in the general formula (1) are determined by the compounds R1—[(O—R2 )k—OH]m, R3—(NCO)h+i and HO—(R4—O)n—R5. The charge ratios among the three compounds are not particularly restricted and should preferably be such that the ratio between the isocyanate group derived from the polyisocyanate and the hydroxyl group derived from the polyether polyol and the polyether monoalcohol is chosen in the NCO / OH range between 0.8:1 and 1.4:1.

In addition, the ratio of the ethylene group occupying R2 should preferably be in the range of 50 to 100% by mass relative to the total amount of R2. In such cases, the appropriate associative thickener for the purposes of the present invention is obtained.

[0249] Furthermore, it is possible to use a polyisocyanate having a urethane bond obtained by reacting said polyisocyanate compound with a polyol. As a polyol, di- to octahydric polyols are preferable, and the polyols listed above are preferred. In cases where a trihydric or higher polyisocyanate is used as the polyisocyanate represented by the formula R3-(NCO)n+l, it is preferable to use said polyisocyanate having the urethane bond.

[0251] The compound represented by the general formula (1) can be produced, for example, by heating at a temperature of 80 to 90 °C for 1 to 3 hours and thus causing a reaction to occur in the same way as that in the ordinary reaction of a polyether and an isocyanate.

[0319] To determine how treatment with Inventive Composition C and Comparative Compositions A and B affects hair, tests were carried out on commercially available hair strands (CP3 bleached hair, 2 gm, 15 cm). All hair strands were initially washed with a standard shampoo before treatment with one of the compositions A to C. Approximately 0.4 gram of each composition per gram of hair was applied to the washed hair strands and distributed evenly throughout. After distribution, the compositions were left on the hair for 10 minutes and then thoroughly rinsed. The hair strands were then blow-dried and treated with a flat iron (180 °C).The flat iron was passed over the hair strands three times for 10 seconds each time (the flat iron was passed along the length of the hair strands (15 cm) for 10 seconds per pass). The strands were assessed, and images of the hair strands are provided in [Fig. 1]. Next, the hair strands underwent a humidity treatment. The hair strands were placed in a humidity chamber at a temperature of 25 °C and 80% RH for 1 hour. After 1 hour in the humidity chamber, the strands were assessed again. Images of the strands subjected to the humidity treatment are shown in [Fig. 2].

[0320] Following the moisture treatments, the strands were again cleaned with standard shampoo and evaluated. Images of the strands are provided in [Fig. 3]. The hair strands were again subjected to a moisture test. The hair strands were again placed in the humidity chamber at a temperature of 25 °C and 80% RH for 1 hour. After 1 hour in the humidity chamber, the strands were evaluated again. Images of the strands subjected to moisture treatment are shown in [Fig. 4].

[0321] Figure 4 shows that the hair strands treated with Inventive Composition C exhibited better fiber alignments, less frizz, more smooth texture, and less roughness at the ends of the hair fibers compared to the placebo and compared to the hair strands treated with Comparative Compositions A and B. This illustrates that Inventive Composition C provided improved fiber alignments, less frizz, more texture, and less roughness at the ends of the hair, and that the improvement is durable, lasting longer than that provided by Comparative Compositions A and B.

The embodiments described herein are further intended to explain the best known means 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 particular applications or uses thereof. Accordingly, the description is not intended to limit the invention to the form disclosed herein.The attached claims are also intended to be interpreted as including other embodiments.

[0325] As used herein, the terms "comprising", "having" and "including" are used in their broad and non-limiting sense.

[0326] The terms "a", "an", "the" and "the" are understood to include the plural and the singular. Thus, the phrase "one of their mixtures" also applies to "their mixtures." Throughout the disclosure, the phrase "one of their mixtures" is used after a list of items, as shown in the following example where the letters A through F represent the items: "one or more items chosen from the group consisting of A, B, C, D, E, F, and one of their mixtures." The phrase "one of their mixtures" does not require that the mixture include all of the items A, B, C, D, E, and F (although all of A, B, C, D, E, and F could be included). Rather, it indicates that a mixture of two or more of A, B, C, D, E, and F could be included. In other words, it is equivalent to the wording "one or more items chosen 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."

[0327] Similarly, the expression "one of their salts" also refers to "their salts". Thus, when the disclosure refers to "an item chosen from the group consisting of A, B, C, D, E, F, one of their salts, and one of their mixtures", 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.

[0328] The salts referred to throughout the disclosure may include salts having a counterion such as an alkali metal, alkaline earth metal, or ammonium counterion. This list of counterions, however, is not exhaustive. The appropriate counterions for the components described herein are known in art.

[0329] The expression "one or more" means "at least one" and therefore includes individual components as well as mixtures / combinations.

[0330] The term “plurality” means “more than one” or “two or more”.

[0331] Except in operational examples, or unless otherwise indicated, all numbers expressing quantities of ingredients and / or reaction conditions may in all cases be modified by the term "approximately", meaning to within + / - 5% the number indicated.

[0332] All percentages, parts and ratios herein are based on the total weight of the compositions of the present invention, unless otherwise indicated.

[0333] Some of the various identified component categories 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 unique will serve only as a surfactant or non-ionic emulsifier or only as a fatty compound (the unique compound does not simultaneously serve as both a surfactant or non-ionic emulsifier and a fatty component).

[0334] A "rinse-out" product refers to a composition that is rinsed and / or washed from the hair with water after or during its application to the hair, and before drying and / or styling the hair. At least a portion of the composition is removed from the hair during rinsing and / or washing.

[0335] A "leave-in" product refers to a composition that is not rinsed and / or washed from the hair after or during its application. The composition remains on the hair during drying and / or throughout styling.

[0336] As used herein, all provided ranges are intended to include each specific range within the given ranges, as well as a combination of intermediate subranges. Thus, a range of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as subranges 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 can serve as a minimum or maximum value to derive a subrange, etc.

[0337] The composition of this case optionally includes one or more surfactants and / or emulsifiers, for example, one or more nonionic, anionic, cationic, and / or amphoteric / zwitterionic surfactants. The terms "surfactants" and "emulsifiers" include the 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 the salts are also encompassed to the extent that such salts exist, even if the disclosure description 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 "one of their salts" or "their salts." Sodium and potassium are common cations that form salts with surfactants and emulsifiers.However, additional cations such as ammonium ions, or alkanoammonium ions such as monoethanolammonium or triethanolammonium ions, can also form surfactant salts.

[0338] The expression "substantially free" or "essentially free" as used here means that less than about 2% by weight of a specific material is added to a composition, relative to 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.

[0339] All components presented positively in this disclosure may be excluded negatively from the claims, for example, a com- The claimed position may be "exempt", "essentially exempt" (or "substantially free") of one or more components that are positively presented in this disclosure.
