Description

Title of Invention: Hair Treatment Compositions and Methods for Straightening Hair FIELD OF DISCLOSURE

[0001] The present disclosure relates to a hair treatment composition and methods of treating hair with the hair treatment composition. Treated hair exhibits improved fiber alignment, frizz control, and a smooth texture. CONTEXT

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

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

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

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

[0006] The need remains to improve hair manageability, for example, to improve hair alignment, to reduce unwanted volume (particularly a reduction in frizz), and to increase shine. SUMMARY OF DISCLOSURE

[0007] The present disclosure relates to hair treatment compositions and methods for improving the appearance, feel, and style of hair. In particular, the hair treatment compositions and methods improve fiber alignment, reduce frizz, and impart a smooth texture. The treated hair is supple, shiny, and has a healthy appearance. The compositions include a unique combination of components that form a smooth coating on the surface of the hair, which is surprisingly durable. The coating and the improved cosmetic properties imparted to the hair are long-lasting, resistant to humidity, and maintained even after washing the hair.

[0008] The hair treatment compositions of the present disclosure typically comprise: a. citric acid, one of its salts or one of its combinations; b. one or more cyclodextrins, their derivatives, or a combination thereof;

[0010] wherein all weight percentages are based on a total weight of the composition.

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

[0012] Cyclodextrins are a family of cyclic oligosaccharides, composed of a macrocyclic core of glucose subunits joined by α-linkages 1,4 glycosidic. Cyclodextrins are produced from starch by enzymatic conversion. Typical cyclodextrins contain a number of glucose monomers ranging from six to eight units in a ring, creating a cone shape, for example, α (alpha)-cyclodextrin has 6 glucose subunits, β (beta)-cyclodextrin has 7 glucose subunits, and γ (gamma)-cyclodextrin has 8 glucose subunits.

Methods

[0160] As explained throughout the present disclosure, the hair treatment compositions are particularly useful in methods of treating hair, preferably human hair, particularly human head hair. Treatment with the compositions improves fiber alignment, reduces frizz, and imparts a smooth texture to the hair. The methods typically comprise applying a hair treatment composition of the present disclosure to the hair. The hair is preferably wet or damp, but the composition can also be applied to dry hair. Application of the compositions to the hair will moisten the hair because the compositions are aqueous (containing a large portion of water).

[0161] The hair treatment composition may be left on the hair for a period of time before being rinsed from the hair. In various embodiments, the hair treatment composition is left on the hair for 1 minute to about 60 minutes before being rinsed from the hair. In other embodiments, the hair treatment composition is left on the hair for about 1 minute to about 45 minutes, about 1 minute to about 30 minutes, about 1 minute to about 15 minutes, about 5 minutes to about 60 minutes, about 5 minutes to about 45 minutes, about 5 minutes to about 30 minutes, about 5 minutes to about 15 minutes, about 5 minutes, about 10 minutes, about 15 minutes, about 20 minutes, about 25 minutes, about 30 minutes, about 40 minutes, about 45 minutes, or about 60 minutes, before being rinsed from the hair.In this view, the hair treatment composition is considered a "rinse-out" product that nevertheless remains on the hair for a period of time before rinsing.

[0162] After rinsing the hair, the hair may be dried, for example with a hair dryer. Once the hair is dry, the hair may be treated with a thermal treatment (with heat). For example, the hair may be treated with a hot iron, in particular, a flat iron. Typically, the hot iron is passed over the hair at least once, at least twice, at least three times, or more. The iron hot is preferably at a temperature of about 120°C to about 250°C, preferably 140°C to about 250°C, more preferably about 150°C to about 200°C.

[0163] An implementation of the present disclosure is provided by means of the following examples. These examples serve to illustrate the technology without being limiting in nature. Example 1 (Compositions)

[0166] ** Based on extrapolation. Example 2

[0167] The compositions of the table of Example 1 were incorporated into a hair treatment routine and the resulting cosmetic attributes of the hair subjected to the routine were evaluated. The routine was performed using strands of medium bleached (CP 3) curly hair. The hair strands were first cleansed with a standard shampoo. After cleansing the hair strands, they were subjected to the following routine. 1. The hair strands were treated with one of the compositions of Example 1 (A, B or C) (approximately 150 mg of composition per gram of hair) or with water, as a placebo. The compositions of Example 1 (A, B or C) (and water for the placebo) were individually massaged into the hair strands and left on the hair for approximately 10 minutes. After 10 minutes, the compositions were rinsed from the hair. 2. After rinsing the compositions from the hair, the hair strands were dried with a hairdryer and treated with a flat iron at a temperature of 180°C. The hot iron was passed over the hair strands three times (for about 10 seconds per pass) and initially evaluated. The results are shown in [Fig. 1]. 3. The wicks were then placed in a humidity chamber (80%, 25°C) for 1 hour and evaluated again. The results are shown in [Fig.2], 4. After treatment in the humidity chamber, the strands were then shampooed and allowed to air dry and evaluated again. The results are shown in [Fig.3]. 5. After the strands were air-dried and evaluated (discussed above), the hair strands were again placed in a humidity chamber (80%, 25°C), for 1 hour, and then evaluated. The results are shown in [Fig.4].

[0168] The results show that Inventive Composition C provided the hair strands with the best fiber alignment, the lowest degree of frizz (best frizz control), and the greatest smooth texture, as shown upon initial treatment, after 1 hour in a humidity chamber, after shampooing, and after shampooing with an additional 1 hour in a humidity chamber. The hair strands treated with Inventive Composition C exhibited a surprising degree of fiber alignment, a surprising degree of frizz reduction, and a surprising degree of smooth texture. When the composition is devoid of propylene carbonate (Comparative Composition B), the same degree of alignment, frizz reduction, and smooth texture was not achieved.Furthermore, when the composition is devoid of citric acid and cyclodextrin (but includes propylene carbonate), the same degree of alignment, frizz reduction and smoothness has not been achieved. The data show the criticality of including all citric acid, cyclodextrin, and propylene carbonate.

[0169] The above data describes treatment according to the present disclosure and subsequent exposure to moisture, followed by washing with shampoo and further subsequent exposure to moisture. It should be noted that the trend shown by the data continued throughout the multiple wash cycles. Treatment with Inventive Composition C provided the hair strands with the best fiber alignment, the lowest degree of frizz (best frizz control), and the greatest smooth texture, even after multiple cleansings of the hair with shampoo on multiple occasions, which was not the case when the hair was treated with Comparative Compositions A and B.

The expression "a mixture thereof" does not require that the mixture include all of A, B, C, D, E, and F (although all of A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of two or more of A, B, C, D, E, and F may be included. In other words, it is equivalent to the formulation "one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture of two or more of A, B, C, D, E and F".

[0173] Similarly, the expression "a salt thereof" also relates to "salts thereof". Thus, when the disclosure refers to "an element selected from the group consisting of A, B, C, D, E, F, a salt thereof, and a mixture thereof", it indicates that one or more of A, B, C, D and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included, or a mixture of any two of A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included.

[0174] 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 limiting. Suitable counterions for the components described herein are known in the art.

[0175] The expression “one or more” means “at least one” and therefore includes individual components as well as mixtures / combinations.

[0176] The term “plurality” means “more than one” or “two or more.”

[0177] Except in working examples, or if otherwise indicated, all numbers expressing amounts of ingredients and / or reaction conditions may be modified in all cases by the term "about", meaning to within + / - 5% of the number indicated.

[0178] All percentages, parts and ratios herein are based on the total weight of the compositions of the present invention, unless otherwise indicated.

[0179] 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 fat component. If a particular composition includes both a nonionic surfactant or emulsifier and a fat compound, a single compound will serve solely as the nonionic surfactant or emulsifier or solely as the fat component (the single compound does not serve as both a nonionic surfactant or emulsifier and a fat component).

[0180] A "rinse-off" product refers to a composition that is rinsed and / or washed from the hair with water after or during application of the composition 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.

[0181] A "leave-in" product refers to a composition that is not rinsed and / or washed out of the hair after or during application of the composition to the hair. The composition remains on the hair during drying and / or throughout styling.

[0182] As used herein, all ranges provided are intended to include each range specific 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 may serve as a minimum or maximum value to derive a subrange, etc.

[0183] The composition of the present 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 salts of the surfactants and emulsifiers even if not explicitly stated. In other words, whenever the disclosure refers to a surfactant or emulsifier, it is intended that salts are also encompassed to the extent that such salts exist, even though the specification may not specifically refer to a salt (or may not refer to a salt in all instances throughout the disclosure), for example, by using language such as "a salt thereof" or "salts thereof." Sodium and potassium are common cations that form salts with surfactants and emulsifiers.However, additional cations such as ammonium ions, or alkanolammonium ions such as monoethanolammonium or triethanolammonium ions, can also form surfactant salts.

[0184] The term "substantially free" or "essentially free" as used herein means that less than about 2% by weight of a specific material is added to a composition, based on the total weight of the compositions. However, the compositions may include less than about 1% by weight, less than about 0.5% by weight, less than about 0.1% by weight, or none of the specified material.

[0185] Any components positively presented in the present disclosure may be negatively excluded from the claims, for example, a claimed composition may be "free", "essentially free" (or "substantially free") of one or more components that are positively presented in the present disclosure.
