Description

Leave-in hair treatment compositions FIELD OF DISCLOSURE

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

CONTEXT

Many people suffer from dry, weak and damaged hair. Dryness and damage can occur due to several factors, including exposure to weather, mechanical treatments ( e.g., hair brushing), and chemical treatments ( e.g., bleaching, etc.). Chemical treatments often alter the appearance of hair by altering 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. The damage leads to split ends, dry straw-like hair, hair that breaks easily, and hair that is “frizzy” and unmanageable. As the visible part of the hair is dead, it cannot regenerate. Many over-the-counter and salon treatments are supposed to repair damaged hair. These include conditioners, hot oil hydrolyzed proteins, vitamin formulations and exotic fruit, leaf or root extracts. However, these treatments provide little improvement to the hair. Therefore, hair repair and revitalization technologies that restore hair properties to their natural form are needed.

SUMMARY OF DISCLOSURE

The leave-in hair treatment compositions and methods of the present disclosure provide a variety of benefits to 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 greasy character despite the very large amount of oil. The leave-in hair treatment composition includes:

(a) water;

(b) about 5 to about 40% by weight of one or more polyols chosen from glycerin, ethylene glycol, propylene glycol, butylene glycol, hexylene glycol, pentylene glycol, diethylene glycol, dipropylene glycol, 1,3 propanediol, and a mixture thereof;

(c) at least 20% by weight of one or more oils; And

(d) at least 0.5% of one or more non-polymeric and non-thiol C1-C9 mono-, di- and/or tri-carboxylic acids;

in which the ratio ((a)+(b)) to (c) is from about 1:1 to about 1:5; And

In a preferred embodiment, the leave-in hair treatment composition includes N-(2-hydroxyethyl) urea (hydroxyethyl urea).

The total amount of the one or more humectants, if present, will vary. However, in various embodiments, the leave-in hair treatment composition includes about 0.1 to about 10 weight percent of the one or more humectants, based on the total weight of the leave-in hair treatment composition. In other embodiments, the leave-in hair treatment composition includes about 0.1 to about 8% by weight, about 0.1 to about 5% by weight, about 0.1 to about 4% by weight, weight, about 0.5 to about 10% by weight, about 0.5 to about 8% by weight, about 0.5 to about 5% by weight, about 0.5 to about 4% by weight, about 1 to about 10% by weight, about 1 to about 8% by weight, about 1 to about 5% by weight, or about 1 to about 4% by weight, based on the total weight of the leave-in hair treatment composition.

(i) Miscellaneous ingredients

In various embodiments, the leave-in hair treatment composition includes one or more various ingredients. Miscellaneous ingredients are ingredients that are compatible with the leave-in hair treatment composition and do not disrupt or materially affect the fundamental and novel properties of the compositions. Non-limiting examples of ingredients include preservatives, fragrances, pH correctors, salts, chelating agents, buffers, antioxidants, flavonoids, vitamins, botanical extracts, UV filter agents, proteins , protein hydrolysates and/or isolates, fillers, compositional dyes, cationic polymers, fatty compounds that are not oils (fatty compounds that are solid at room temperature), etc.

For the purposes of this disclosure, fatty compounds which are not oils are fatty compounds which are solid at room temperature. Non-limiting examples include waxes, fatty acids and fatty alcohols which are solid at room temperature, etc. The leave-in hair treatment compositions of the present disclosure optionally include one or more fatty compounds that are not oils (one or more fatty compounds that are solid at room temperature). Although the fatty compounds are solid at room temperature, when combined with other components, for example, when combined in the hair treatment compositions of the present disclosure, the compounds are generally not solid because they solubilize or interact with the other compounds in the composition.

For the purposes of the present disclosure, a "colorant of the composition" is a compound which 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 hairs. Styling gels, for example, can be found 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 hair color.

In various embodiments, the various preferred ingredients are chosen from preservatives, perfumes, pH correctors, salts, chelating agents, buffers, composition dyes, fatty compounds which are not oils (compounds solid fats), and mixtures thereof.

The total quantity of the miscellaneous ingredient(s), if present, will vary. However, in various embodiments, the reducing composition includes from about 0.001 to about 10 weight percent of one or more miscellaneous ingredients, based on the total weight of the reducing composition. In other embodiments, the reducing compositions include from about 0.001 to about 5 wt.%, from about 0.001 to about 3 wt.%, from about 0.01 to about 10 wt.%, from about 0.01 to about 5 wt.%, about 0.01 to about 3 wt.%, about 0.1 to about 10 wt.%, about 0.1 to about 5 wt.%, or from about 0.1 to about 3% by weight of one or more miscellaneous ingredients, based on the total weight of the reducing composition.

pH

The pH of leave-in hair treatment compositions will vary. However, in various embodiments, the pH of the composition is from about 3 to about 6. In other embodiments, the pH of the compositions is from about 3 to about 5.5, from about 3 to about about 5, about 3 to about 4.5, about 3 to about 4, about 3.5 to about 6, about 3.5 to about 5.5, about 3.5 to about 5, about 3.5 to about 4.5, about 4 to about 6, about 4 to about 5.5 or about 4 to about 5.

The compositions of the present disclosure are useful in hair treatment methods. For example, the methods are particularly effective in imparting durability to hair, hydrating hair, and moistening hair. The methods include applying a leave-in hair treatment composition according to the present disclosure to the hair, and optionally styling the hair. As the name suggests, the “leave-in” hair treatment composition stays on the hair.

Viscosity

The viscosity of leave-in hair treatment compositions will vary. However, it is preferred that the viscosity be approximately 100 to 20,000 cps at 25 ^o C measured using a Brookfield DV-LL+ Pro Viscometer using pin C of the Helipath T-bar and a speed rotation of 50 rpm. In other embodiments, the viscosity is about 100 to about 15,000 cps, about 100 to about 10,000 cps, about 100 to about 5,000 cps, about 500 to about 20,000 cps, about 500 to about 15 000 cps, approx. 500, approx. about 5,000 cps, about 5,000 to about 20,000 cps, about 5,000 to about 15,000 cps, about 5,000 to about 10,000 cps, about 10,000 to about 20,000 cps, about 10,000 to about 15,000 cps, or approximately 15,000 to approximately 20,000 cps at 25 ^o C measured with a Brookfield DV-LL+ Pro viscometer using the Helipath C T spindle and a rotation speed of 50 rpm.

Example 2 (Performance)

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 three different treatment protocols, described below.

1. CONTROL: The hair strands were first cleaned with standard shampoo (0.4 ml/g of hair, 30 seconds of massage and 1 min. leave to act, rinse and remove excess water from the hair ). After cleaning, 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.

2. INVENTIVE: The hair strands were first cleaned with standard shampoo (0.4 ml/g of hair, 30 seconds of massage and 1 min. leave to act, rinse and remove excess water from the hair ). After cleaning, 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.

3. INVENTIVE: One week after treating the hair strands according to (2) above, the hair strands were cleaned with standard shampoo (0.4 ml/g of hair, 30 seconds of massage and 1 min . leave to act, rinse and remove excess water from the hair). After cleaning the hair, the hair was blow dried using a high/warm setting for approximately 3 minutes.

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

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

The CFTT was used to measure cycles to breakage (CJR), which assesses the number of repeated elongations and relaxations of the hair until breakage; Each elongation causes a pre-specified stress that maintains fiber deformation in the elastic region of the hair type, simulating daily hair care. Improvements in this metric indicate a greater ability of hair to resist fatigue.

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

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. The 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 connected by the same number are statistically significant.

The data shows 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 hair hydration and moistening, leading to lower breakage stress compared to protocol (1) (control), due to of 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 lower plateau stress and higher elongation at break than hair treated with protocol (1) (control) and hair treated with protocol (2) (6 treatments), and a Young's modulus lower than the 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 moisture evidenced by hair treated according to Protocol (2) (6 treatments) and Protocol (3) (6 treatments and cleansing) are significant and astonishing.

Definitions

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

As used herein, the terms “comprising”, “having” and “including” are used in their broad and non-limiting sense.

The term “oil” refers to any fatty substance that is in liquid form at room temperature (25°C) and atmospheric pressure.

The term “solid fatty compound” is a fatty compound that is not an oil, that is, any fatty substance that is a solid at room temperature (25°C) and atmospheric pressure.

The term “hydrocarbon oil” is interchangeable with the term “hydrocarbon oil” and designates an oil containing primarily hydrogen and carbon atoms.

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 containing Si-O groups.

The expression “fluorinated oil” means an oil comprising at least one fluorine atom.

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

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. The volatile oil is a volatile cosmetic oil, which is liquid at room temperature, in particular having a non-zero vapor pressure, at room temperature and at atmospheric pressure, in particular having 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 preferably ranging from 1.3 Pa to 1300 Pa (0.01 to 10 mmHg).

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

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.

The term “non-silicone emulsifier” is interchangeable with the term “non-silicone emulsifier” and refers to an emulsifier that does not contain silicon atoms.

The term "rinsable" as used herein indicates that the composition is used in a context where the composition is ultimately rinsed or washed from a treated surface (e.g., skin, hair, or hard surfaces) after or during the treatment. application of the product. These rinse-off compositions must be distinguished from “no-rinse” compositions. For example, a rinse-out 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 .

A "leave-in" (also called leave-in) composition means a composition applied to the hair and which is not subject to immediate rinsing and/or washing, for example for at least 4 hours or for a period of 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 it was styled, that is, it is not removed from the hair before styling the hair.

For the purposes of the present disclosure, the term “nonionic emulsifier” is interchangeable with the term “nonionic surfactant”. A 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.

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.

The term "transparent" in relation 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. of a Lambda 40 UV-visible spectrometer. The term “clear” is interchangeable with the term “transparent” within the meaning of the present 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.

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 blurry and difficult if not impossible to read, although movement and structure can normally be identified.

An “opaque” composition is one that is not transparent or translucent.

In the context of the present disclosure, a "colorant of the composition" 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 hairs. Styling gels, for example, can be found 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 hair color.

The terms “un”, “une”, “le” and “la” are understood to include the plural and the singular. Thus, the expression “a mixture of” also concerns “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 through 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 phrase "a mixture thereof" does not require that the mixture include all elements A, B, C, D, E and F (although all elements A, B, C, D, E and F may be included). Rather, it indicates that a mixture of two or more of elements 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”.

Likewise, the expression "a salt thereof" also refers to "salts thereof". Thus, when the disclosure refers to "an element chosen from the group consisting of A, B, C, D, E, F, a salt of the latter, or a mixture of the latter", 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.

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

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

Some of the various component categories 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 represents no more than one component. For example, a fatty acid can 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 only as an emulsifier or only as a fatty compound (the single fatty acid does not serve as both an emulsifier and a fatty compound).

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, however, not exhaustive.

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

In this document, all ranges provided are intended to include each specific range within the given ranges, as well as a combination of intermediate subranges. So a range of 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 combinable. For example, any value or point described herein that falls within a range described herein may be used as a minimum or maximum value to derive a subrange, etc.

Any components positively set forth 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 which are presented in a positive manner in this disclosure. For example, silicones may optionally be included in the compositions, but preferably the compositions are free or substantially free of silicones. Silicones are synthetic polymers made up of repeating units of elemental siloxane, silicon and oxygen, combined with other elements, most commonly carbon and hydrogen. Silicones are therefore also called polysiloxanes.

The term "substantially free" or "substantially 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. All components presented herein may be optionally included or excluded from the compositions/processes/requirements. When excluded, the compositions/processes/kits may be free or essentially free of the component. For example, a particular composition may be free or essentially free of alkoxylated compounds, for example, ethoxylated thickeners and/or ethoxylated surfactants. Likewise, a particular composition may be free or essentially free of sulfates, such as sulfate surfactants.

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 stated to be 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 control.

The compositions described throughout this disclosure may be "leave-in" compositions. A “leave-in” (also called leave-in) 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 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.
