Description

Title of Invention: Leave-in Hair Treatment Compositions FIELD OF DISCLOSURE

[0001] The present disclosure relates to leave-in hair treatment compositions and methods of treating hair. CONTEXT

[0002] Many individuals suffer from dry, weakened, and damaged hair. Dryness and damage can occur due to several factors, including exposure to the elements, mechanical treatments (e.g., brushing the hair), and chemical treatments (e.g., bleaching, etc.). Chemical treatments often alter the appearance of hair by changing 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. The damage leads to split ends, dry, straw-like hair, hair that breaks easily, and hair that is "frizzy" and unmanageable.Since the visible part of the hair is dead, it cannot regenerate. Many over-the-counter and salon treatments are designed to repair damaged hair. These include conditioners, hot oil hydrolyzed proteins, vitamin formulations, and extracts of exotic fruits, leaves, or roots. However, these treatments provide little improvement to the hair. Therefore, hair repair and revitalization technologies that restore hair's properties to their natural form are needed. SUMMARY OF DISCLOSURE

[0003] The leave-in hair treatment compositions and methods of the present disclosure provide a variety of benefits to the hair. For example, the compositions and methods strengthen the hair fiber, protect the hair fibers from damage (or further damage), and improve cosmetic attributes such as softness, conditioning, and healthy appearance. The compositions include an unusually high amount of oil, but are stable, translucent, or transparent, with a unique gel-like consistency. The compositions strengthen the hair and moisten / hydrate the hair without greasiness despite the very high amount of oil. The hair treatment composition no-rinse includes:

[0242] Tests were carried out to determine how treatment with Composition A influences the hair fiber. Tests were carried out on strands of Caucasian hair, treated according to one of the three different treatment protocols, described below.

[0243] 1. WITNESS: The strands of hair were first cleaned with shampoo standard (0.4 ml / g of hair, 30 seconds of massage and 1 min. leave on, rinse and remove excess water from the hair). After cleansing, the hair strands were subjected to six treatments with deionized water. Deionized water was applied to the hair strands six times in a row. The hair strands were allowed to dry after each application of deionized water.

[0244] 2. INVENTIVE: The locks of hair were first cleaned with a standard shampoo (0.4 ml / g of hair, 30 seconds of massage and 1 min. leave on, rinse and remove excess water from the hair). After cleansing, the hair strands were subjected to six treatments with composition A. For each treatment, composition A was applied to the hair strands (0.15 g / g of hair) massaged into the hair for 1 minute, combed through the hair 5 times, and the hair was blow-dried using a high / hot setting for approximately 3 minutes. The treatment process was carried out six times in a row.

[0245] 3. INVENTIVE: One week after treatment of the hair strands In accordance with (2) above, the hair strands were cleansed with a standard shampoo (0.4 ml / g of hair, 30 seconds massage and 1 min. leave on, rinse and remove excess water from the hair). After cleansing the hair, the hair was blow-dried using a high / hot setting for approximately 3 minutes.

[0246] Tests were conducted to determine how the three treatment protocols described above influence the hair. The hair was analyzed by differential scanning calorimetry (DSC, DSC-2500, TA Instruments), miniature tensile testing (MTT, MTT-686, Dia-Stron Ltd) and cyclic fatigue tensile testing (CFTT, CYC802, Dia-Stron Ltd). Each individual test was conducted with fifty (50) hair fibers per treatment.

[0247] DSC was used to measure the denaturation temperature, which is a measure of the thermal stability of proteins in hair.

[0248] The CFTT was used to measure cycles to failure (CTF), which assesses the Number of repeated elongations and relaxations of the hair until breakage; each elongation causes a pre-specified stress that keeps the fibers deformed in the elastic region of the hair type, simulating daily hair care. Improvements in this metric indicate a greater ability of the hair to resist fatigue.

[0249] The MTT was used to measure Young's modulus, i.e., the slope of the initial portion of the stress-strain curve, which is adjusted to make a cross-section, representing a measure of the spring-like structure of the hair. It also measures plateau stress, which is the average stress during the plateau region of the fiber's stress-strain curve (~15% strain); breaking stress, which is the total force required to break the hair fiber; elongation at break, which represents the total deformation of the hair at the point of failure; and toughness, i.e., the extent of the hair's ability to absorb energy before fracture.

[0250] The test results were subjected to statistical analysis using Tukey boxes with k=3, to determine and exclude significant outliers. Student's t-test at 95% confidence interval was used to analyze significant differences in DSC and MTT results. Log-Rank test at 95% confidence interval was used to analyze significant differences in cycles to failure. The results are presented in the tables below and the corresponding figures. Levels not related by the same number are statistically significant.

[0258] The data show that hair treated according to protocol (2) (6 treatments) modifies the hair fiber and improves its durability compared to hair treated according to protocol (1) (control). Hair treated according to protocol (2) (6 treatments) also appears to improve hydration and humidification of the hair, leading to a lower breaking strain compared to Protocol (1) (control), due to the solvation of weak bonds. Hair treated according to Protocol (3) (6 treatments and cleansing) supported the benefits conferred by Protocol (2) (6 treatments). This indicates that Composition A penetrates deep into the hair fiber with improved retention. Hair treated with Protocol (3) (6 treatments and cleansing) had a lower plateau strain and higher elongation at break than hair treated with Protocol (1) (control) and hair treated with Protocol (2) (6 treatments), and a lower Young's modulus than hair treated according to Protocol (1) (control), which was particularly surprising. This suggests further hydration of the fiber leading to plasticization.The improved durability, hydration and moisturization evidenced by hair treated according to Protocol (2) (6 treatments) and Protocol (3) (6 treatments and cleansing) are significant and astonishing. Definitions

[0259] The term “hair and / or body hair” as used herein includes head hair, beard hair, mustache hair, eyebrows, eyelashes, and body hair, unless otherwise specified.

[0260] As used herein, the terms "comprising," "having," and "including" are used in their broad and non-limiting sense.

[0261] The term “oil” means any fatty substance which is in liquid form at room temperature (25°C) and atmospheric pressure.

[0262] The term "solid fatty compound" is a fatty compound that is not an oil, i.e., any fatty substance that is a solid at room temperature (25°C) and atmospheric pressure.

[0263] The term "hydrocarbon oil" is interchangeable with the term "hydrocarbon oil" and means an oil containing primarily hydrogen and carbon atoms.

[0264] The term "silicone-based oil" is interchangeable with the term "silicone oil" and the term "organosiloxane oil" and is an oil containing silicone atoms, particularly oils having Si-O groups.

[0265] The expression "fluorinated oil" means an oil comprising at least one fluorine atom.

[0266] The oils may optionally comprise oxygen, nitrogen, sulfur and / or phosphorus atoms, for example in the form of hydroxyl or acid radicals.

[0267] For the purposes of the present invention, the expression "volatile oil" designates an oil (or a non-aqueous medium) capable of evaporating on contact with the skin in less than one hour, at room temperature and atmospheric pressure. Volatile oil is a volatile cosmetic oil, which is liquid at room temperature, having in particular a non-zero vapor pressure, at room temperature and at atmospheric pressure, having in particular a vapor pressure ranging from 0.13 Pa to 40,000 Pa (10-3 to 300 mmHg), preferably ranging from 1.3 Pa to 13,000 Pa (0.01 to 100 mmHg) and preferentially ranging from 1.3 Pa to 1300 Pa (0.01 to 10 mmHg).

[0268] For the purposes of the present disclosure, the expression “non-volatile oil” designates an oil whose vapor pressure is less than 0.13 Pa.

[0269] The term "silicone emulsifier" is interchangeable with the term "silicone-based emulsifier" and the term "organosiloxane emulsifier" and refers to an emulsifier containing one or more silicon atoms.

[0270] The term "non-silicone emulsifier" is interchangeable with the term "non-silicone-based emulsifier" and refers to an emulsifier that does not contain silicon atoms.

[0271] The term "rinse-off" as used herein indicates that the composition is used in a context where the composition is ultimately rinsed or washed off a treated surface (e.g., skin, hair, or hard surfaces) after or during application of the product. Such rinse-off compositions are to be distinguished from "leave-on" compositions. For example, a rinse-off composition is applied to the hair, may remain on the hair for a short period of time (e.g., a few seconds up to about 5, 10, or 15 minutes), and is then rinsed from the hair before styling the hair.

[0272] A "leave-in" (also called leave-in) composition means a composition applied to the hair and which is not subjected to immediate rinsing and / or washing, for example for at least 4 hours or for a period ranging from 4 hours to 72 hours, from 4 hours to 48 hours, or from 8 hours to 36 hours, or from 8 hours to 24 hours. In other words, the product is applied to the hair and remains on the hair, as styled, i.e. it is not removed from the hair before styling the hair.

[0273] For the purposes of this disclosure, the term "nonionic emulsifier" is interchangeable with the term "nonionic surfactant." Reference to a nonionic emulsifier (or nonionic surfactant) in the leave-in hair treatment compositions of the present disclosure does not indicate that the composition is an emulsion. In various embodiments, the leave-in hair treatment composition is an emulsion, but in various embodiments, the leave-in hair treatment composition is not an emulsion.

[0274] The leave-in hair treatment composition of the present disclosure may be in the form of an emulsion, for example, a microemulsion, a water-in-oil emulsion, an oil-in-water emulsion, a micellar emulsion, or a bicontinuous emulsion, but it is not necessarily in the form of an emulsion. In a preferred embodiment, the leave-in hair treatment composition is a microemulsion. In a preferred embodiment, the leave-in hair treatment composition is a bicontinuous emulsion, preferably a bicontinuous microemulsion.

[0275] The term "transparent" with respect to a transparent composition indicates that the composition has a transmittance of at least 80% at a wavelength of 600 nm, measured, for example, using a Lambda 40 UV-visible spectrometer. The compositions may have, for example, a transmittance of at least 80%, at least 90%, or at least 95% at a wavelength of 600 nm, measured, for example, using a Lambda 40 UV-visible spectrometer. The term "clear" is interchangeable with the term "transparent" for the purposes of this disclosure. A person can typically see through a transparent composition, for example, and read the text on the other side of a clear glass or clear plastic bottle containing the composition.

[0276] The term "translucent" in relation to a translucent composition indicates that the composition has a transmittance of at least 50% at a wavelength of 600 nm, measured for example using a Lambda 40 UV-visible spectrometer. A person probably cannot see through a translucent composition, for example, and read the text on the other side of a clear glass or clear plastic bottle containing the composition. Instead, the text is usually blurred and difficult if not impossible to read, however movement and structure can normally be identified.

[0277] An “opaque” composition is a composition that is not transparent or translucent.

[0278] In the context of the present disclosure, a "composition colorant" is a compound that colors the composition but does not have an appreciable coloring effect on the hair. That is, the composition colorant is included to provide coloring to the composition for aesthetic appeal, which is not intended to impart coloring properties to the hair. Hair styling gels, for example, can come in a variety of different colors (e.g., light blue, light pink, etc.), but applying the styling gel to the hair does not change the color of the hair.

[0279] The terms "a," "an," "the," and "the" are understood to encompass both the plural and the singular. Thus, the expression "a mixture of" also relates to "mixtures of." Throughout the disclosure, the expression "a mixture thereof" is used, after a list of elements as shown in the following example where the letters A to F represent the elements: "one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture thereof." 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."

[0280] Similarly, the phrase "a salt thereof" also refers to "salts thereof." Thus, when the disclosure refers to "a member selected from the group consisting of A, B, C, D, E, F, a salt thereof, or 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.

[0281] The expression “one or more” means “at least one” and therefore includes individual components as well as mixtures / combinations.

[0282] 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.

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

[0284] Salts referred to throughout the disclosure may include salts having a counterion such as an alkali metal, an alkaline earth metal, or an ammonium counterion. This list of counterions is not, however, limiting.

[0285] The term "treat" (and its grammatical variations) are used herein to refer to the application of the compositions of the present disclosure to the surface of keratinous substrates such as hair.

[0286] In this document, all ranges provided are intended to include each specific range within the given ranges, as well as a combination of intermediate sub-ranges. Thus, a range of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as sub-ranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc. All ranges and The 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.

[0287] 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. By way of example, silicones may optionally be included in the compositions but, preferably, the compositions are free or essentially free of silicones. Silicones are synthetic polymers consisting of repeating units of the elemental siloxane, silicon and oxygen, combined with other elements, most commonly carbon and hydrogen. Silicones are therefore also referred to as polysiloxanes.

[0288] 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. Any components set forth herein may be optionally included in or excluded from the compositions / methods / kits. When excluded, the compositions / methods / kits may be free or essentially free of the component. For example, a particular composition may be free or essentially free of alkoxylated compounds, e.g., ethoxylated thickeners and / or ethoxylated surfactants.Similarly, a particular composition may be free or essentially free of sulfates, such as sulfate surfactants.

[0289] All publications and patent applications cited herein are incorporated by reference, and for all purposes, as if each individual publication or patent application were specifically and individually indicated as being 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.

[0290] The compositions described throughout this disclosure may be "leave-on" compositions. A "leave-on" (also referred to as leave-on) composition refers to a composition that is applied to the skin or hair and is not subject to immediate rinsing and / or washing, for example for at least 4 hours or for a period of time in the range of 4 hours up to 72 hours, 4 hours up to 48 hours, or 8 hours up to 36 hours, or from 8 hours up to 24 hours. In other words, the product is applied to the hair and remains on the hair, as it was styled, that is, it is not removed from the hair before styling the hair.
