Description
TITLE
LEAVE-ON HAIR TREATMENT COMPOSITIONS
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims benefit of U.S. Serial No. 17/936,440, filed September 29, 2022, and benefit of French Application No. FR 2212546, filed on November 30, 2022, which are incorporated herein by reference in their entirety.
FIELD OF THE DISCLOSURE
The present disclosure relates to leave-on hair treatment compositions and methods for treating hair.
BACKGROUND
Many individuals suffer from dry, weak, and damaged hair. Dryness and damage can occur due to several factors including weather exposure, mechanical treatments (e.g. brushing hair), and chemical treatments (e.g., bleaching, etc.). Chemical treatments often change the look of hair by changing its physical structure, which inevitably causes a certain 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 to the protein structure of the individual hair strands or shafts. Damage results in split ends, dry straw-like hair, hair that is easily broken, and hair that is “frizzy” and unmanageable. Because the visible portion of hair is dead, it cannot regenerate itself. Numerous over the counter and salon treatments purport to repair damaged hair. These include conditioners, hot oil hydrolyzed proteins, vitamin formulations, and exotic fruit, leaf, or root extracts. Such treatments, however, provide only limited improvements to the hair. Therefore, hair repair and conditioning technologies that restore the properties of hair to its natural form are needed.
SUMMARY OF THE DISCLOSURE
The leave-on hair-treatment compositions and methods of the instant disclosure provide a variety of benefits to hair. For example, the compositions and methods strengthen the hair fiber, protect hair fibers from damage (or from further damage), and improve cosmetic attributes such as softness, conditioning, and healthy appearance. The compositions include an unusually high amount of oil, yet
are stable, translucent, or transparent, with a unique gel-like consistency. The compositions strengthen hair and moisturize/hydrate the hair without greasiness despite containing the very high amount of oil. The leave-on hair-treatment composition includes:
(a) water;
(b) about 5 to about 40 wt.% of one or more polyols selected 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 wt.% of one or more oils; and
(d) at least 0.5 % of one or more C1-C9 non-polymeric and non-thiol, mono-, di-, and/or tri-carboxylic acids; wherein the ratio of ((a)+(b)) to (c) is about 1 :1 to about 1 :5; and all percentages by weight are relative to a total weight of the composition.
Preferably, the composition is transparent or translucent. In addition, the composition preferably has a pH of about 3 to about 6.
In various embodiments, at least one of the one or more oils is a hydrocarbonbased oil. In various embodiments, at least one of the one or more oils is a silicone- based oil (or simply a “silicone oil”).

(i) Miscellaneous Ingredients
In various embodiments, the leave-on hair treatment composition includes one or more miscellaneous ingredients. Miscellaneous ingredients are ingredients that are compatible with the leave-on hair treatment composition and do not disrupt or materially affect the basic and novel properties of the leave-on hair treatment compositions. Nonlimiting examples of ingredients include preservatives, fragrances, pH adjusters, salts, chelating agents, buffers, antioxidants, flavonoids, vitamins, botanical extracts, LIV filtering agents, proteins, protein hydrolysates, and/or isolates, fillers, composition colorants, cationic polymers, fatty compounds that are not oils (fatty compounds that are solid at room temperature), etc.
For purposes of the instant disclosure fatty compounds that are not oils are fatty compounds that are solid at room temperature. Nonlimiting examples include waxes, fatty acids and fatty alcohols that are solid at room temperature, and the like. The leave-on hair treatment compositions of the instant 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 instant disclosure, the compounds are not generally solid because they solubilize or interact with the other compounds in the composition.
For purposes of the instant disclosure, a “composition colorant” is a compound that colors the composition but does not have an appreciable coloring effect on hair. In other words, the composition colorant is included to provide a coloring to the composition for aesthetic appeal, which is not intended to impart coloring properties to hair. Styling gels, for example, can be found in a variety of different colors (e.g., light blue, light pink, etc.) yet application of the styling gel to the hair does not change the color of the hair.
In various embodiments, preferred miscellaneous ingredients are chosen from preservatives, fragrances, pH adjusters, salts, chelating agents, buffers, composition colorants, fatty compounds that are not oils (solid fatty compounds), and mixtures thereof.
The total amount of the one or more miscellaneous ingredients, if present, will vary. Nonetheless, in various embodiments, reducing composition includes about
0.001 to about 10 wt.% of one or more miscellaneous ingredients, based on the total weight of the reducing composition. In further embodiments, the reducing compositions include from about 0.001 to about 5 wt.%, about 0.001 to about 3 wt.%, about 0.01 to about 10 wt.%, 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 about 0.1 to about 3 wt.% of one or more miscellaneous ingredients, based on the total weight of the reducing composition. pH
The pH of the leave-on hair treatment compositions will vary. Nonetheless, in various embodiments, the pH of the composition is from about 3 to about 6. In further embodiments, the pH of the compositions is from about 3 to about 5.5, about 3 to 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 instant disclosure are useful in methods for treating hair. For instance, the methods are particularly effective for imparting durability to hair, hydrating the hair, and moisturizing hair. The methods include applying a leave- on hair treatment composition according to the instant disclosure to hair, and optionally styling the hair. As the name indicates, the “leave-on” hair treatment composition remains on the hair.
Viscosity

Example 2 (Performance)
Testing was carried out to determine treatment with Composition A influences hair fiber. Testing was carried out on Caucasian hair swatches, treated according to one of three different treatment protocols, described below.
1 . CONTROL: Hair swatches were initially cleansed with a standard shampoo (0.4 ml/g hair, 30 seconds massage, and 1 min. leave-in, rinse, and excess water squeezed out from the hair). After cleansing, the hair swatches were subjected to six treatments with deionized water. Deionized water was applied to the hair swatches six consecutive times. The hair swatches were allowed to dry after each application of deionized water.
2. INVENTIVE: Hair swatches were initially cleansed with a standard shampoo (0.4 ml/g hair, 30 seconds massage, and 1 min. leave-in, rinse, and excess water squeezed out from the hair). After cleansing, the hair swatches were subjected to six treatments with Composition A. For each treatment, Composition A was applied to the hair swatches (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 high/hot setting for about 3 minutes. The treatment process was carried out six consecutive times.
3. INVENTIVE: One week after the hair swatches were treated according to (2) above, the hair swatches were cleansed with a standard shampoo (0.4 ml/g hair, 30 seconds massage, and 1 min. leave-in, rinse, and excess water squeezed out from the hair). After cleansing the hair, the hair was blow dried using high/hot setting for about 3 minutes.
Testing was carried out to determine how the three treatment protocols described above influence the hair. The hair was analyzed with 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 carried out using 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.
CFTT was used to measure cycles to break (CTB), which asseses the number of repeated extensions and relaxations of the hair fiber until breakage; each extension causes a pre-specified stress that maintains the fiber deformation within the elastic region of the hair type, simulating everyday hair grooming. Improvements in this metric indicate a higher ability for the hair to resist fatigue.
MTT was used to measure Young’s Modulus, i.e., slope of the initial portion of the stress-strain curve, which is adjusted for cross-sectional area, representing a measure of the hair spring-like structure. It also measures plateau stress, which is the average stress during plateau region of fiber’s stress-strain curve (-15% strain); break stress, which is the total force needed to break hair fiber; break extension, which represents the total strain of hair fibers at break point; and toughness, i.e., the extent of the hair’s ability to absorb energy before fracture.
Test results were subjected to statistical analysis using Turkey’s fences 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 outputs. Log-Rank test at 95% confidence interval was used to analyze significant differences in cycles to break. The results are presented in the tables below and the corresponding figures. Levels not connected by the same number are statistically significant.
The data show that hair treated according to Protocol (2) (6 treatments) modifies the hair fiber and improves durability versus hair treated according to Protocol (1 ) (Control). Hair treated according to Protocol (2) (6 treatments) also appears to improve hydration and moisturization of the hair fiber, leading to a lower break stress versus Protocol (1) (Control), due to solvation of weak bonds. Hair treated according to Protocol (3) (6 treatments and cleanse) sustained the benefits provided 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 treatment and cleanse) exhibited a lower plateau stress and higher break extension 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 suprising. This suggests further hydration of the fiber leading to plasticization. The improved durability, hydration, and moisturization exhibited by the hair treated according to Protocol (2) (6 treatments) and Protocol (3) (6 treatments and cleanse) is significant and surprising.
Definitions
The term “hair” as used herein includes hair of the head, beard hair, mustache hair, eyebrow hair, eyelashes, and body hair, unless otherwise specified.
As used herein, the terms “comprising,” “having,” and “including” are used in their open, non-limiting sense.
The term “oil” means any fatty substance that is in liquid form at room temperature (25°C) and at atmospheric pressure.
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 at atmospheric pressure.
The term “hydrocarbon-based oil” is interchangeable with the term “hydrocarbon oil” means an oil mainly containing hydrogen and carbon atoms.
The term “silicone-based oil” is interchangeable with the term “silicone oil” and the term “oganosiloxane oil” and is an oil containing silicone atoms, especially oils having Si-0 groups.
The term “fluoro oil” means an oil comprising at least one fluorine atom.
The oils may optionally comprise oxygen, nitrogen, sulphur and/or phosphorus atoms, for example in the form of hydroxyl or acid radicals.
For the purposes of the present invention, the term “volatile oil” means an oil (or non-aqueous medium) capable of evaporating on contact with the skin in less than one hour, at room temperature and at atmospheric pressure. The volatile oil is a volatile cosmetic oil, which is liquid at room temperature, especially having a nonzero vapour pressure, at room temperature and atmospheric pressure, in particular having a vapour 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).
For the purposes of the present disclosure, the term “non-volatile oil” means an oil with a vapour pressure of less than 0.13 Pa.
The term “silicone emulsifier” is interchangeable with the term “silicone-based emulsifier” and the term “oganosiloxane emulsifier” and refers to an emulsifier containing one or more silicone atoms.
The term “non-silicone emulsifier” is interchangeable with the term “non- silicone-based emulsifier” and refers to an emulsifiers that does not contain silicone atoms.
The term “rinse-off” as used herein indicates that the composition is used in a context whereby the composition is intended to be rinsed or washed from a treated surface, (e.g. skin, hair, or hard surfaces) either after or during the application of the product. These rinse-off compositions are to be distinguished from compositions referred to a “leave-on” compositions. For example, a rinse-off composition is applied to the hair, optionally allowed to remain on the hair for a short time (e.g., a few second up to about 5, 10, or 15 minutes) and subsequently rinsed from the hair before the hair styled.
A "leave-on" (also called leave-in) composition refers to a composition that is applied to hair and is not subjected to immediate rinsing and/or washing, for example for at least 4 hours or for a period of time ranging from 4 hours up to 72 hours, from 4 hours up to 48 hours, or from 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 styled, i.e., it is not removed from the hair prior to styling the hair.
For purposes of the instant disclosure the term “nonionic emulsifier” is interchangeable with the term “nonionic surfactant.” Reference to a nonionic emulsifier (or nonionic surfactant) in the leave-on hair treatment compositions of the instant disclosure does not indicate that the composition is an emulsion. In various embodiments, the leave-on hair treatment composition is an emulsion but in various embodiments, the leave on hair-treatment composition is not an emulsion.
The leave-on hair treatment composition of the instant 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-on hair treatment composition is a microemulsion. In a preferred embodiment, the leave-on hair treatment composition is a bicontinous emulsion, preferably a bicontinous microemulsion.
The term "transparent” with respect to a transparent composition indicates that the composition has transmittance of at least 80% at a wavelength of 600 nm,
for example measured 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 purposes of the instant disclosure. A human 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” with respect to a translucent composition indicates that the composition has a transmittance of at least 50% at a wavelength of 600 nm, for example measured using a Lambda 40 UV-visible spectrometer. A human cannot likely 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. Rather, the text is usually blurred and difficult or not possible to read, yet movement and structure can normally be identified.
An “opaque” composition is a composition that is not transparent or translucent.
In the context of the instant disclosure, a “composition colorant” is a compound that colors the composition but does not have an appreciable coloring effect on hair. In other words, the composition colorant is included to provide a coloring to the composition for aesthetic appeal, which is not intended to impart coloring properties to hair. Styling gels, for example, can be found in a variety of different colors (e.g., light blue, light pink, etc.) yet application of the styling gel to the hair does not change the color of the hair.
The terms “a,” “an,” and “the” are understood to encompass the plural as well as the singular. Thus, the term “a mixture thereof” also relates to “mixtures thereof.” Throughout the disclosure, the term “a mixture thereof” is used, following a list of elements as shown in the following example where letters A-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 term, “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 any two or more of A, B, C, D, E, and F can be included. In other words, it is equivalent to the phrase “one or more
elements selected from the group consisting of A, B, C, D, E, F, and a mixture of any two or more of A, B, C, D, E, and F.”
Likewise, the term “a salt thereof” also relates to “salts thereof.” Thus, where 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 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 include, 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 thus includes individual components as well as mixtures/combinations.
Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions may be modified in all instances by the term “about,” meaning within +/- 5% of the indicated number.
Some of the various categories of components identified may overlap. In such cases where overlap may exist and the composition includes both components (or the composition includes more than two components that overlap), an overlapping compound 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 as only the emulsifier or only the fatty compound (the single fatty acid does not serve as both the emulsifier and the fatty component).
The salts referred to throughout the disclosure may include salts having a counter-ion such as an alkali metal, alkaline earth metal, or ammonium counter-ion. This list of counter-ions, however, is non-limiting.
The term “treat” (and its grammatical variations) as used herein refers to the application of the compositions of the present disclosure onto the surface of keratinous substrates such as hair.
As used herein, all ranges provided are meant to include every specific range within, and combination of sub ranges between, the given ranges. Thus, a range from 1-5, includes specifically 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 values disclosed herein are inclusive and combinable. For examples, 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.
All components positively set forth throughout the instant disclosure may be negatively excluded from the claims, e.g., a claimed composition may be “free,” “essentially free” (or “substantially free”) of one or more components that are positively set forth in the instant disclosure. As an example, silicones can optionally be included in the compositions but preferably the compositions are free or essentially free from silicones. Silicones are synthetic polymers made up of repeating units of siloxane, elemental silicon and oxygen, combined with other elements, most often carbon and hydrogen. Thus, silicones are also called polysiloxanes.
The term “substantially free” or “essentially free” as used herein means that there is less than about 2% by weight of a specific material added to a composition, based on the total weight of the compositions. Nonetheless, the compositions may include less than about 1 wt.%, less than about 0.5 wt.%, less than about 0.1 wt.%, or none of the specified material. All of the components set forth herein may be optionally included or excluded from the compositions/method/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, 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 in this specification are herein incorporated by reference, and for any and all purposes, as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. In the event of an inconsistency between the present disclosure and any publications or patent application incorporated herein by reference, the present disclosure controls.
The compositions described throughout this disclosure may be a “leave-on” composition. A "leave-on" (also called leave-in) composition refers to a composition
that is applied to skin or hair and is not subjected to immediate rinsing and/or washing, for example for at least 4 hours or for a period of time ranging from 4 hours up to 72 hours, from 4 hours up to 48 hours, or from 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 styled, i.e., it is not removed from the hair prior to styling the hair.
