Description

Title of the invention: ANHYDROUS HAIR TREATMENT COMPOSITION comprising a cationic surfactant and a fatty alcohol SCOPE OF DISCLOSURE

[0001] This disclosure relates to anhydrous hair treatment compositions comprising cationic surfactants and fatty alcohols, and methods of treating hair with the compositions. The compositions and methods are useful for smoothing hair, treating split ends, and controlling frizz. BACKGROUND

[0002] Many consumers wish to 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 imparting various cosmetic properties to the hair, 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, dyes, heat, nutrients, etc. Even cleansing products tend to remove the hair's natural oils, causing dryness and potentially leading to a dull appearance and split ends. People with curly hair may also face additional challenges when caring for their hair.Curly hair tangles more easily and can be more difficult to style.

[0003] Environmental factors, such as salt water, sunlight, and heat, as well as chemical treatments, are also known to damage hair. Various types of chemical treatments include, for example, hair bleaching and coloring, perms, perming products, and straightening treatments. These chemical treatments change the appearance of hair by altering its physical structure, which inevitably causes some degree of hair damage. Damaged hair is characterized by unnatural changes in the protein structure of individual hair strands or shafts. The damage results in split ends, dry, straw-like hair, hair that breaks easily, and hair that is frizzy and difficult to style. Since the visible part of the hair is dead, it cannot regenerate itself.

[0004] Many over-the-counter and salon treatments are intended to repair damaged hair. Silicones, for example, are used to provide lubrication and shine. Silicones work by coating the cuticle, the outermost layer of the hair fiber. Silicones are often found in conditioners because they increase slip, help retain moisture, and leave hair feeling soft. The increased slip makes detangling easier. Silicones are also used for their anti-frizz properties because they can form a coating on the hair that resists moisture, which causes frizz. However, silicones can build up on the hair and leave a residue that is difficult to wash out. Ultimately, the residue prevents moisture from being absorbed into the hair, leading to dryness and damage over time.Furthermore, silicones can weigh down hair, especially fine hair, causing it to lose volume and elasticity.

[0005] Products that condition hair include rinse-out conditioners, leave-in conditioners, deep conditioning treatments, and co-wash conditioners. Rinse-out conditioners are the most common type of conditioning product. They are applied after shampooing and rinsed out before drying and styling. Rinse-out conditioners typically remain on the hair for only a few minutes before being rinsed out, but they are suitable for most hair types and can be used daily or as needed.

[0006] Leave-in conditioners are usually applied to the hair after shampooing and are not rinsed out. They remain on the hair during drying and styling and are designed to provide long-lasting moisture and nourishment, making them a popular choice for dry or damaged hair. Leave-in conditioners can also offer additional benefits such as heat protection, frizz control, and detangling. They are especially useful for people who frequently style their hair or who need extra moisture throughout the day.

[0007] All-in-one shampoos / conditioners, also called "co-wash" or "conditioning shampoos," attempt to combine the cleansing benefits of a shampoo with the conditioning properties of a conditioner. They cleanse the hair while simultaneously conditioning it, making for a convenient and simplified hair care routine. Cleansing compositions, such as shampoos, are designed to remove sebum, oil, and debris from the hair, which is the opposite of conditioning. Many conditioning products are designed to deliver oil and other conditioning agents to the hair. In addition, shampoos Effective conditioners cause the hair cuticle to open, which helps release and remove debris. Effective conditioners, on the other hand, are designed to close the cuticle to prevent moisture release and provide extra protection for the hair. A single product cannot both open and close the cuticle simultaneously.

[0008] Conditioning products on the market come in various forms, such as solutions, lotions, creams, sprays, oils, and even aerosols. Regardless of the form, consumers are looking for lightweight products that do not weigh down the hair or leave it with a greasy or oily texture. Conditioned hair should have a natural, healthy appearance, a pleasant shine, and a natural flow. Ideal conditioning products moisturize the hair, provide protection against heat and other environmental damage, and control frizz and flyaways.

[0009] The formulation of environmentally friendly cosmetic products, designed and developed with environmental considerations in mind, is also becoming a major objective in an effort to address global challenges. It is therefore essential to offer more sustainable compositions, preparation processes, and ingredients to meet these environmental concerns. In this context, it is important to develop new cosmetic compositions with a lower carbon footprint, particularly by promoting the use of renewable raw materials and / or materials with a high naturalness index and / or materials of natural origin, and more specifically, materials of plant origin, while reducing the use of petrochemical-derived compounds. DISCLOSURE SUMMARY

[0010] This disclosure relates to an anhydrous hair treatment composition that instantly provides hair with softness, hydration, and other conditioning benefits. The composition includes castor oil, one or more cationic surfactants, and one or more fatty alcohols. Fatty alcohols behave as nonionic surfactants due to their amphipathic nature. Notably, despite the presence of both cationic surfactants and fatty alcohols, the composition is not an emulsion; rather, it is a homogeneous and transparent solution in which the cationic surfactants and fatty alcohols are solubilized.

[0011] Surfactants have a polar head and an oily tail. In emulsions, water and other polar organic compounds form an aqueous phase that interacts with the polar heads of the surfactants. Fatty compounds such as oils create a hydrophobic phase of the emulsion that interacts with the oily tails of the surfactants. In the absence of water, monoalcohols having 1 to 6 carbon atoms, glycols Polyols, containing 1 to 6 carbon atoms, and / or other polyols with 1 to 6 carbon atoms are typically used to incorporate surfactants into oils. The inventors have remarkably discovered a unique formulation that effectively solubilizes both cationic surfactants and fatty alcohols, resulting in a clear solution that moisturizes, softens hair, treats split ends, and controls frizz when used with water.

[0012] The composition of an anhydrous hair treatment typically includes: a. one or more vegetable oils, in which one or more of the vegetable oils is castor oil in an amount of at least 10% by weight, relative to the total weight of the anhydrous hair treatment composition; b. one or more cationic surfactants; c. one or more fatty alcohols; and d. optionally, one or more sensory-active agents;

[0013] all percentages by weight are based on a total weight of the composition.

[0014] Upon contact with water, the anhydrous hair treatment composition undergoes a transformation into a structured lamellar arrangement. Cationic surfactants and fatty alcohols assemble at the oil-water interface, positioning their hydrophobic tails toward the oil and their hydrophilic heads toward the water molecules. This molecular alignment forms bilayers, or lamellae, efficiently trapping and transporting oil droplets within these layers onto the hair during application. When applied to wet or damp hair, the presence of water triggers the development of the lamellar structure. Consequently, the oil droplets are deposited on the hair surface. Unlike conventional conditioners that use oils, cationic surfactants, and fatty alcohols for conditioning, the unique lamellar mechanism formed with the anhydrous hair treatment composition when used with water ensures a more efficient and thorough deposition process.This formula effectively deposits substantial amounts of oil, cationic surfactants, and other active ingredients onto the hair. Unlike other water-based conditioning products, hair treated with this anhydrous hair treatment formula is moisturized without becoming sticky, greasy, or weighed down. It leaves hair feeling light and soft with a natural shine and a healthy appearance.

[0015] Preferably, the anhydrous hair treatment composition is free or essentially free of monoalcohols having from 1 to 6 carbon atoms and polyhydric alcohols having from 1 to 6 carbon atoms. In addition, the anhydrous hair treatment composition is also preferably free or essentially free of alpha-hydroxy acid esters.

The anhydrous hair treatment composition can be formulated and used as a leave-in product or formulated and used as a rinse-out product. Preferably, however, the anhydrous hair treatment composition is a leave-in product that is applied to the hair, for example, wet or damp hair. After application to wet or damp hair, the anhydrous hair treatment composition is allowed to dry naturally or can be force-dried, for example, with a hairdryer. The anhydrous hair treatment composition is used in hair revitalization processes, hair hydration, frizz control, adding shine and improving the appearance and feel of hair. DETAILED DESCRIPTION OF THE DISCLOSURE

[0031] This case relates to an anhydrous hair treatment composition that provides softness, hydration, and conditioning benefits to the hair, and to hair treatment processes using the anhydrous hair treatment composition. The anhydrous hair treatment composition is typically used as a leave-in product but is also useful as a rinse-out product. The anhydrous hair treatment composition moisturizes the hair, reduces or prevents frizz, improves curl definition, and imparts softness and shine to the hair. The anhydrous hair treatment composition typically includes: a. about 10 to about 95% by weight of one or more vegetable oils, in which one or more of the vegetable oils is castor oil in an amount of at least 10% by weight; b. approximately 0.1 to approximately 10% by weight of one or more cationic surfactants; c. approximately 0.1 to approximately 10% by weight of one or more fatty alcohols; and d. Optionally, approximately 0.1 to approximately 5% by weight of one or more agents sensorially active;

[0032] in which all percentages by weight are based on a total weight of the composition.

[0033] Preferably, the anhydrous hair treatment composition is free or essentially free of monoalcohols having from 1 to 6 carbon atoms and free or essentially free of polyhydric alcohols having from 1 to 6 carbon atoms. In addition, in various embodiments, the anhydrous hair treatment composition is further, or alternatively, free or essentially free of alpha-hydroxy acid esters. The anhydrous hair treatment composition may further, or alternatively, be essentially free of acetals and ketals having 10 carbon atoms or fewer. A non-limiting example of a ketal having 10 carbon atoms or fewer is isopropylidene glycerol. In a preferred embodiment, the anhydrous hair treatment composition is free or essentially free of isopropylidene glycerol. a. Vegetable oils#

[0034] The anhydrous hair treatment composition includes one or more vegetable oils, provided that one or more of the vegetable oils is castor oil (also known as "castor seed oil") in a quantity at least 10% by weight, relative to the total weight of the anhydrous hair treatment composition. For the purposes of this disclosure, vegetable oils are oils derived from plants that are liquid at room temperature (25°C, 1 atm) or can be solubilized with other vegetable oils and exist in liquid form at room temperature. For example, coconut oil may be solid at room temperature, but if solubilized in castor oil, it exists in liquid form at room temperature. Vegetable oils are derived from various plant sources, such as nuts, almonds, grape seeds, olives, and avocados. For example, coconut oil is extracted from the pulp, olive oil from the fruit, and jojoba oil from the seed. Vegetable oils are typically obtained by pressing, which can be either cold or hot.Cold pressing involves pressing the plant to extract the oil without raising the temperature above 40°C. Hot pressing involves heating the plant, which increases the oil yield but can alter its quality.

[0035] For the purposes of this disclosure, the term "vegetable oil" does not include essential oils, and the term "essential oil" does not include vegetable oils, even though essential oils are obtained from plants. In cases where dual use exists such that a particular oil can be interpreted as both a vegetable oil and an essential oil, a single oil cannot serve simultaneously as both a vegetable oil and an essential oil in the composition of an anhydrous hair treatment.

[0036] The total amount of one or more vegetable oils in the anhydrous hair treatment composition will vary but is typically from about 10 to about 95% by weight, relative to the total weight of the anhydrous hair treatment compositions. In other embodiments, the composition of the anhydrous hair treatment includes approximately 10 to approximately 90% by weight, approximately 10 to approximately 80% by weight, approximately 10 to approximately 70% by weight, approximately 10 to approximately 65% ​​by weight, approximately 20 to approximately 95% by weight, approximately 20 to approximately 90% by weight, approximately 20 to approximately 80% by weight, approximately 20 to approximately 70% by weight, approximately 20 to approximately 65% ​​by weight, approximately 35 to approximately 95% by weight, approximately 35 to approximately 90% by weight, approximately 35 to approximately 80% by weight, approximately 35 to approximately 70% by weight, approximately 35 to approximately 65% ​​by weight, approximately 35 to approximately 55% by weight, approximately 35 to approximately 50% by weight, approximately 35 to approximately 45% by weight, approximately 40 to approximately 75% by weight,approximately 40 to approximately 65% ​​by weight, approximately 40 to approximately 55% by weight, approximately 45 to approximately 75% by weight, approximately 45 to approximately 65% ​​by weight, approximately 45 to approximately 55% by weight, approximately 50 to approximately 75% by weight, approximately 50 to approximately 70% by weight, approximately 50 to approximately 65% ​​by weight, approximately 50 to approximately 60% by weight, approximately 55 to approximately 75% by weight, approximately 55 to approximately 70% by weight, or approximately 55 to approximately 65% ​​by weight, of one or more vegetable oils, relative to the total weight of the anhydrous hair treatment composition. Preferably, the anhydrous composition includes from about 10 to about 70% by weight, more preferably from about 45 to about 65% by weight, and even more preferably from about 50 to about 65% by weight of one or more vegetable oils, relative to the total weight of the hair treatment composition. (a)(i) Castor oil

[0037] Castor oil is a vegetable oil pressed from castor beans. It is a colorless or pale yellow liquid with a boiling point of about 313 °C (595 °F) and a density of about 0.961 g / cm³. It comprises a mixture of triglycerides in which about 90% of the fatty acids are ricinoleates. Oleic acid and linoleic acid are other important components. Thus, castor oil is well known as a source of ricinoleic acid, an 18-carbon monounsaturated fatty acid. Among fatty acids, ricinoleic acid is unusual in that it has a hydroxyl functional group on the twelfth carbon atom. This functional group makes ricinoleic acid (and castor oil) more polar than many other oils.

[0038] The anhydrous hair treatment composition typically includes a substantial amount of castor oil, preferably at least 10% by weight or more of castor oil, relative to the total weight of the anhydrous hair treatment composition. For example, the anhydrous hair treatment composition may include approximately 10 to approximately 95% by weight of castor oil, relative to the total weight of the anhydrous hair treatment composition. In other embodiments, the anhydrous hair treatment composition includes approximately 10 to approximately 55% by weight, approximately 10 to approximately 50% by weight, approximately 10 to approximately 45% by weight, approximately 10 to approximately 40% by weight, approximately 10 to approximately 37.5% by weight, approximately 15 to approximately 55% by weight, approximately 15 to approximately 50% by weight, approximately 15 to approximately 45% by weight, approximately 15 to approximately 40% by weight, approximately 15 to approximately 37.5% by weight, approximately 20 to approximately 55% by weight,from approximately 20 to approximately 50% by weight, from approximately 20 to approximately 45% by weight, from approximately 20 to approximately 40% by weight, from approximately 20 to approximately 37.5% by weight, from approximately 25 to approximately 55% by weight, from approximately 25 to approximately 50% by weight, from approximately 25 to approximately 45% by weight, from approximately 25 to approximately 40% by weight, from approximately 25 to approximately 37.5% by weight, from approximately 30 to approximately 60% by weight, from approximately 30 to approximately 55% by weight, from approximately 30 to approximately 50% by weight, from approximately 30 to approximately 45% by weight, from approximately 30 to approximately 40% by weight, from approximately 30 to approximately 37.5% by weight, from approximately 35 to approximately 55% by weight, from approximately 35 to approximately 50% by weight, approximately 35 to approximately 45% by weight, or approximately 35 to approximately 40% by weight of castor oil, relative to the total weight of the composition of, anhydrous hair treatment. The composition of anhydrous hair treatment preferably includes about 10 to about 80% by weight, more preferably about 15 to about 60% by weight, and even more preferably about 25 to about 50% by weight of castor oil, relative to the total weight of the composition of anhydrous hair treatment.

[0039] (a)(ii) Additional vegetable oils (other than castor oil)

[0040] As mentioned above, the anhydrous hair treatment composition preferably includes one or more additional vegetable oils (other than castor oil), i.e. the anhydrous hair treatment composition includes two or more (or a plurality of) vegetable oils, provided that one of the two or more (or a plurality of) vegetable oils is castor oil.

In a preferred embodiment, the anhydrous hair treatment composition includes castor oil and one or more additional vegetable oils selected from coconut oil, soybean oil, avocado oil, peanut oil, apricot oil, argan oil, avocado oil, babassu oil, cottonseed oil, camelina oil, camellia oil, safflower oil, and peanut oil, preferably coconut oil and / or soybean oil.

[0041] In a preferred embodiment, the anhydrous hair treatment composition includes castor oil and one or more additional vegetable oils selected from coconut oil and soybean oil. In a preferred embodiment, the hair treatment composition includes castor oil and coconut oil.

(d) Sensory-active agents.

[0071] A sensory-active agent is a substance or compound that provides or causes an individual (a human) to experience a sensation, for example a sensation on the skin, a pleasant odor and / or a pleasant taste. Non-limiting examples include essential oils, cooling agents, warming agents, terpenes, and terpenoids. There is dual use between essential oils, cooling agents, warming agents, and terpenes and / or terpenoids. For example, menthol can be supplied as an essential oil, is a cooling agent, and is a terpene. In cases where dual use exists, only one substance or compound will be interpreted as an essential oil, a cooling agent, a warming agent, a terpene, and / or a terpenoid. A single substance or compound does not act simultaneously as more than one essential oil, cooling agent, warming agent, or terpene and / or terpenoid.For example, when menthol is included in an anhydrous hair treatment composition, menthol is interpreted as an essential oil if it is included or added as an essential oil, or menthol serves as a cooling agent or terpene.

[0072] The total amount of one or more sensorially active agents in the anhydrous hair treatment composition, if present, will vary but is typically about 0.05 to about 8% by weight, relative to the total weight of the anhydrous hair treatment composition.

(d)(i) Essential oils

[0073] The composition of an anhydrous hair treatment may include one or more essential oils. Essential oils are concentrated liquid extracts of aromatic plants, typically in the form of volatile oils containing compounds that give the plants their characteristic scents and therapeutic properties. Distillation involves passing steam through the plant, causing the aromatic compounds to evaporate. The steam is then cooled and condensed, separating the essential oil from the water. Essential oils are derived from different parts of the plants, such as the flowers, leaves, bark, and roots. or fruits. For example, lavender essential oil is extracted from the flowers, lemon essential oil from the peel, and ginger essential oil from the rhizome. Essential oils have a unique chemical composition that can vary within the same plant species, or from one plant to another.

[0074] For the purposes of this disclosure, the term "essential oil" is used in accordance with the European Pharmacopoeia; and essential oils can be identified and characterized according to Do et al., Proposal for a standardised method for the identification of essential oils by HPTLC, Pharmeur. Bio. Sci. Notes. 2021; 2021: 157-166 (PMID: 34751647), which are incorporated herein in their entirety by reference. Essential oils are of plant origin and can therefore fall within the broad spectrum of vegetable oils, but can be considered a specific and unique type of vegetable oil. For the purposes of this disclosure, the term "vegetable oil" does not include essential oils, and the term "essential oil" does not include vegetable oils, even though essential oils are obtained from plants. In cases where dual use could exist such that a particular oil could be interpreted as both a vegetable oil and an essential oil, a single oil cannot serve simultaneously as both a vegetable oil and an essential oil in the composition of an anhydrous hair treatment.

Hair treatment processes

[0122] As its name suggests, anhydrous hair treatment composition is particularly useful in hair processing, especially for human hair. Anhydrous hair treatment composition is useful both as a rinse-out product and as a leave-in product. A "rinse-out" product refers to a composition that is removed by rinsing and / or washing 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. A "leave-in" product refers to a composition that is not removed by rinsing and / or washing the hair after or during application of the composition to the hair. The composition remains on the hair during drying and / or throughout styling.

[0123] Processes of using the anhydrous hair treatment composition include hair care processes, hair revitalization processes, hair hydration processes, hair smoothing processes, hair frizz reduction processes, and processes for improving the Hair shine. The processes include applying an effective amount of the anhydrous hair treatment composition to the hair. For example, the anhydrous hair treatment composition may be applied to hair in need of conditioning, hair in need of hydration, hair in need of smoothing, hair prone to frizz or suffering from frizz, hair in need of shine, or any combination thereof. Furthermore, in a preferred embodiment, the anhydrous hair treatment composition is applied to damaged hair, for example, damaged hair in need of strengthening, hydration, conditioning, smoothing, and / or frizz control.

[0124] In a preferred embodiment, the anhydrous hair treatment composition is applied to wet or damp hair, for example, freshly washed and optionally conditioned hair. After rinsing out shampoo and optionally rinsing out conditioner, while the hair remains wet or damp, an effective amount of the anhydrous hair treatment composition is applied to the wet or damp hair. During application, the anhydrous hair treatment composition may be distributed by massaging, combing, or otherwise spreading over all of the hair and scalp. Preferably, the anhydrous hair treatment composition is distributed over all of the hair, including the ends.Once the anhydrous hair treatment composition has been distributed throughout the hair, it can be removed by rinsing the hair, or the hair can be washed with shampoo and optionally treated with conditioner. In this embodiment, the anhydrous hair treatment composition is a rinse-off product. Before rinsing the anhydrous hair treatment composition from the hair or washing the hair with shampoo, the anhydrous hair treatment composition is preferably left on the hair for a period, for example, from about 30 seconds to about 30 minutes. The period can also be from about 1 minute to about 30 minutes, from about 1 minute to about 15 minutes, from about 1 minute to about 10 minutes, from about 1 minute to about 5 minutes, or from about 5 minutes to about 15 minutes.

[0125] Preferably, the anhydrous hair treatment composition is not removed by rinsing or washing the hair but is applied as a leave-in product. After distributing the anhydrous hair treatment composition on wet or damp hair, the anhydrous hair treatment composition is not removed by rinsing or washing the hair. Instead, the hair to which the anhydrous hair treatment composition has been applied is allowed to dry, or it is forcefully dried, for example with a hairdryer, and the hair is styled. Alternatively, the hair can be styled while still wet or damp, and dried later. Preferred modes of implementation

[0174] The preceding disclosure illustrates and describes embodiments of the invention. The disclosure shows and describes only preferred embodiments, but it is understood that the invention is usable in various other combinations, modifications, and environments, and that it may undergo changes or modifications in the scope of the inventive concepts as expressed herein, depending on the teachings above and / or the skills or knowledge of the relevant art. The embodiments described herein are further intended to explain the best known embodiments of the applicant and to enable others skilled in the art to use the disclosure. Accordingly, the description is not intended to limit the invention.

[0175] As used herein, the terms "comprising," "having," and "including" (or "comprise," "have," and "include") are used in their broad, non-limiting sense. The phrase "consisting essentially of" limits the scope of a claim to the materials or steps specified and to those which do not materially affect the basic and innovative features of the claimed invention.

[0176] The terms "a", "an", "the" and "the" are understood to encompass both the plural and the singular.

[0177] Thus, the expression "one of their mixtures" or "one of their combinations" also refers to "their mixtures" or "their combinations." Throughout the disclosure, the expression "one of their combinations" may be used following 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 one of their combinations." The expression "one of their combinations" does not require that the combination include all of the elements A, B, C, D, E, and F (although all of the elements A, B, C, D, E, and F may be included). Rather, it indicates that a combination of any two or more of the elements A, B, C, D, E, and F may be included. In other words, it is equivalent to the expression "one or more elements chosen from the group consisting of A, B, C, D, E, F, and a combination of any two of A, B, C, D, E and F or more".

[0178] Similarly, the expression "one of its (their) salts" also refers to "its (their) salts." Thus, when the disclosure refers to "an element chosen from the group consisting of A, B, C, D, E, F, one of their salts, and one of their combinations," it indicates that one or more of A, B, C, D, and F may be included, that 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 that 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.

[0179] The term "anhydrous" as used herein refers to a substantial absence of water. An "anhydrous" composition, including the anhydrous hair treatment composition of this disclosure, comprises less than 5% by weight of water, preferably less than 3% by weight of water, more preferably less than 2% by weight of water. The anhydrous hair treatment composition may comprise less than 1% by weight of water, less than 0.5% by weight of water, or less than 0.1% by weight of water.

[0180] The surfactants referred to throughout the disclosure may include those having a counterion such as bromide, chloride, fluoride, hydroxide, nitrate, acetate, benzoate, or sulfate. This list of counterions, however, is not exhaustive.

[0181] The expression "one or more" means "at least one" and therefore includes individual components as well as mixtures / combinations.

[0182] The term “plurality” means “more than one” or “two or more”.

[0183] 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 + / - 10% of the stated number. For example, a quantity of "approximately 1 by weight" may include a quantity as low as 0.90% by weight or as high as 1.1. Similarly, a quantity of "approximately 50" may include a quantity as low as 45% by weight and as high as 55% by weight.

[0184] Some of the various categories of ingredients identified for the anhydrous hair treatment composition may have dual function. In cases where dual function may exist and the anhydrous hair treatment composition includes two (or more than two) dual components, a dual component shall not represent more than one claimed component. For example, menthol may be interpreted as both a "cooling agent" and a "terpene." If a claimed anhydrous hair treatment composition includes both a cooling agent and a terpene, the menthol in the anhydrous hair treatment composition shall serve only as a cooling agent or only as a terpene. Menthol may not simultaneously serve as both a cooling agent and a terpene.

[0185] All percentages, parts and ratios herein are based on the total weight of the compositions of the present invention, unless otherwise stated.

[0186] 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 for deducing a subrange, and so on. Furthermore, all ranges provided are intended to include each specific range within the given ranges, and a combination of intermediate subranges within the given ranges. 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, and so on.

[0187] A "rinse-off" product refers to a composition that is removed by rinsing and / or washing the hair with water after or during the 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.

[0188] A "leave-in" product refers to a composition that is not removed by rinsing and / or washing the hair after or during the application of the composition to the hair. The composition remains on the hair during drying and / or throughout styling.

[0189] All components presented positively in this disclosure may be excluded negatively from the claims and the compositions and processes described throughout the disclosure. In other words, the cleaning compositions of the present disclosure may be free or substantially free of one or more of the components presented positively in this disclosure for possible inclusion in cleaning compositions.

[0190] The expression "substantially free" or "essentially free" as used herein means that the specific material may be present in small quantities that do not materially affect the basic and innovative features of the claimed invention. For example, less than 1% by weight of a specific material may be added to a composition, relative to the total weight of the composition (provided that an amount of 1% by weight or less does not materially affect the basic and innovative features of the claimed invention). Similarly, where a composition is essentially free of a particular element, the composition may include 1% by weight or less, 0.5% by weight or less, 0.1% by weight or less, 0.05% by weight or less, or 0.01% by weight or less, or no amount of the specified material.For example, if a composition is "substantially free" or "essentially free" of ethanol, the composition may optionally include ethanol in an amount of up to 1% by weight, relative to the total weight of the composition, provided that 1% by weight does not materially affect the basic and innovative characteristics of the composition. In addition, the composition may optionally include 0.5% by weight or less, 0.1% by weight or less, 0.05% by weight or less, 0.01% by weight or less, or no ethanol at all.
