Description

Title of the invention: Hair treatment composition comprising glycerin ketal / acetal FIELD OF DISCLOSURE

[0001] The present disclosure relates to hair treatment compositions containing one or more glycerin ketal / acetal compounds; and methods for treating hair, e.g., conditioning, facilitating combing, and improving the appearance and feel of the hair. CONTEXT

[0002] Many people suffer from dry and damaged hair. Dryness and damage can occur due to several factors including exposure to weather conditions, mechanical treatments (e.g., brushing hair), excessive processing using chemicals, blow-drying hair, heat styling, etc. In combination, the use of cleansing products that can be excessively stripping of the hair's natural oils can not only lead to split ends and dull hair, but also exacerbate dry hair. To mitigate the damage, oil treatments, conditioner, hair masks, and chemical treatments are commonly used.

[0003] The popularity and use of oils for treating dry hair has increased due to their effectiveness and simplicity. Commonly used oils include olive oil, mineral oil, avocado oil, apricot kernel oil, rice bran oil, and coconut oil. However, one of the problems is that the effects are usually not seen after several hours (e.g., 8 hours) of treatment, and multiple treatments are usually required, making the treatment time-consuming and labor-intensive.

[0004] People desire a treatment for hair or damaged hair that is not time consuming and labor intensive. Various approaches have been developed to revitalize hair. A common method for providing a revitalizing benefit is to use conditioning agents such as cationic surfactants and polymers, high melting point fatty compounds, low melting point oils, silicone compounds, and combinations thereof. Most of these conditioning agents are known to provide various revitalizing benefits.

[0005] However, there is still a need to provide better revita benefits hair conditioning, for example, improved softness, better hair alignment, increased ease of detangling and increased shine. SUMMARY OF DISCLOSURE

Processes

[0138] The hair treatment compositions of the present disclosure are useful for treating hair, for example, for conditioning, facilitating styling, and improving the appearance and feel of the hair. The hair treatment composition is also useful in methods for easily detangling hair. The compositions may be applied to wet or damp hair and may be massaged into the hair, for example, with the hands, and / or spread throughout the hair with a comb or brush. The compositions may remain in the hair or may optionally be rinsed from the hair prior to drying and / or styling the hair. Preferably, the hair treatment compositions are rinsed from the hair after being applied and massaged into the hair.

[0139] The hair treatment compositions, in some embodiments, may be used as a leave-in product. The compositions are applied to wet or damp hair and may remain on the hair indefinitely, i.e., the hair composition is not removed or rinsed from the hair prior to drying or styling the hair.

[0140] The hair treatment methods according to the disclosure also include methods according to various routines. For example, the compositions may be mixed with a shampoo (or conditioner) before application to the hair. Alternatively, the composition may be layered on top of (or lathered into) hair to which the shampoo (or conditioner) is already applied. Furthermore, the composition may be applied separately from the shampoo (or conditioner), i.e., applied to the hair after rinsing the shampoo (or conditioner) from the hair. In some cases, it is preferable to treat the hair with a composition of the present disclosure before shampooing, for example, to apply the composition to wet or damp hair before applying shampoo to the hair. After shampooing, the hair may also be treated (optionally) with a conditioner. Kits

[0141] The hair compositions of the present disclosure may be incorporated into a kit. For example, the kits may include at least one hair treatment composition according to the present disclosure and one or more additional compositions, e.g., a shampoo, a conditioner, etc. The different compositions are contained separately in the kits. In some cases, the kits include one or more compositions according to the present disclosure and a shampoo, which are two separately contained. The kits may also include one or more compositions according to the present disclosure, a shampoo and a conditioner, all of which are separately contained. Instructions, mixing components, brushes, gloves, measuring tools, etc. may also be optionally included in the kits.

[0142] The compositions may be packaged in a variety of different containers, such as, for example, a ready-to-use container. Non-limiting examples of useful packaging include tubes, jars, capsules, unit-dose packages, and bottles, including squeezable tubes and bottles. In some cases, the package is a tube, such as a tube with two compartments, or dual tubes, each forming a separate compartment. Each compartment may include a different composition. For example, one tube or compartment may include a composition according to the present disclosure, and the other tube may include a composition for use with the composition, e.g., a shampoo, conditioner, or all-in-one shampoo / conditioner (i.e., a conditioning shampoo; also referred to as a "co-wash").

[0143] Methods of treating hair according to the disclosure will vary but typically include applying a hair treatment composition of the present disclosure to the hair, leaving the composition on the hair for a sufficient time, and rinsing the compositions from the hair. The composition may be applied to the hair in a sequence with other compositions. For example, the compositions may be applied to the hair before shampooing the hair, after shampooing the hair, before conditioning the hair, and / or after conditioning the hair. However, the compositions do not necessarily have to be used in a sequence.

[0144] The compositions of the present disclosure may remain on the hair for a minimal period of time before being rinsed from the hair, but it is not necessary to leave the composition on the hair. Conveniently, the compositions may be applied and left on the hair for a period of time that is typical for normal shampooing and / or conditioning. For example, the composition (whether combined with another hair treatment composition such as a shampoo or conditioner) may be applied to the hair and left on the hair for a few seconds (1, 2, 3 or 5 seconds) up to about 1, about 2, about 5, about 10, about 15, about 20, about 25 or about 30 minutes.

[0145] The hair treatment composition may be applied to the hair immediately after or before treating the hair with another composition (e.g., shampoo and / or conditioner). For example, the hair treatment compositions may be applied to the hair within about 1, 2, 5, 10, or 20 minutes before or after applying shampoo and / or conditioner. on the hair.

[0146] The compositions of the present disclosure are unique in their ability to provide hair with improved manageability and smooth texture. Accordingly, the present disclosure relates to methods for treating hair, for example, for improving the manageability of hair and for imparting a smooth texture.

[0171] An equal amount of Inventive Composition A and Comparative Composition J of Example 1 was applied to strands of natural hair with a 6-curl pattern and the strands were allowed to air dry. After the hair strands were dry, the strands were visually assessed. Hair treated with Inventive Composition A showed significantly less residue and dandruff than hair treated with Comparative Composition J. Example 3

[0172] Inventive Composition G of Example 1 was tested on hair on the heads of three human volunteers with medium-length, medium to fine, very curly hair with low natural damage, and compared to a commercial reference product. Inventive Composition G is shown in the table below.

[0175] 2 Measured at 25oC with a Brookfield DV-LL+ Pro Viscometer using an RV spindle and a rotation speed of 2 rpm.

[0176] The Commercial Reference includes the following list of ingredients: water, cetearyl alcohol, dimethicone, amodimethicone, behentrimonium chloride, cetearyl alcohol, glycerin, propylene glycol, isopropyl alcohol and miscellaneous ingredients.

[0177] Equal amounts of Inventive Compositions G and Commercial Reference Product were applied to opposite halves of a head of dry hair and the pre-shampoo detangling ease and amount of hair slip were independently assessed by an expert hairdresser. The ease of detangling was assessed by detangling the hair with a wide-toothed comb. The term “slip” refers to the “slipperiness” or “lubricity” of the hair, determined by running fingers through the hair.

[0178] Hair treated with Inventive Compositions G was consistently rated higher for ease of pre-shampoo detangling and slippage than the commercial Reference Product.

[0179] After pre-shampoo detangling, the hair was cleansed with a standard shampoo. The shampoo was rinsed from the hair and the Inventive Compositions G and the Commercial Reference Product were applied to opposite halves of a head of damp hair as a leave-in treatment. Without drying, the ease of detangling and the amount of hair slippage were independently assessed by an expert hairdresser.

[0180] Once the hair was assessed for manageability and slip, it was blow-dried and the smoothness, hydration and flake formation were assessed by an expert hairdresser. Hair treated with Inventive Compositions G was consistently rated higher for smoothness (more smoothness), hydration (more hydration) and flake formation (less flakes).

[0181] The above results are significant considering that Inventive Composition G does not include silicones (e.g., dimethicone and amodimethicone). Silicones are often used in conditioning compositions to aid detangling, provide slip, and improve smoothness and hydration. The data show that the inventive compositions containing a glycerin ketal / acetal (isopropylidene glycerol) as opposed to silicones provided better conditioning properties (ease of detangling, slip, smoothness, hydration, and reduced flake formation) than a commercial reference product formulated and marketed for its conditioning properties. Therefore, it was particularly unexpected to find that the inventive compositions provided better conditioning properties than the commercial reference product containing silicones.

[0182] The terms “comprising”, “having” and “including” are used in their broad and non-limiting sense.

[0183] The terms “a”, “an”, “the” and “the” are understood to include the plural and the singular.

[0184] The compositions and methods of the present invention may comprise, consist of, or consist essentially of the essential elements and limitations of the disclosure described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful.

[0185] A “composition colorant” is a compound or ingredient that colors the composition but has no appreciable coloring effect on the hair. In other words, the A composition colorant is included to impart color to the composition for aesthetic purposes but 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 visibly change the color of the hair. Thus, a composition colorant is different from a hair coloring agent. A composition colorant colors the compositions; a hair coloring agent can (and often does) change the color of the compositions, but it also changes the color of the hair

[0186] The term "rinse-off" as used herein indicates that the composition is used in a context where the composition is ultimately rinsed or washed from the 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 compositions referred to as "leave-on" compositions. For example, a rinse-off composition is applied to the hair, optionally left 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.

[0187] The compositions described throughout this disclosure may be a "leave-on" composition. A "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 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.

[0188] A "lamellar phase" generally refers to the arrangement of long-chain polar head and non-polar tail molecules in a bulk polar liquid environment (i.e., hair water), as sheets of bilayers separated by bulk liquid.

[0189] The term "non-linear fatty acids" as used in the present disclosure refers to an unsaturated fatty acid and / or branched fatty acids.

[0190] 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 may ty prickly 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.

[0191] 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 vial containing the composition. Instead, the text is usually blurred and difficult if not impossible to read, however movement and structure can normally be identified.

[0192] The term "opaque" in relation to an opaque composition indicates that the composition is not transparent or translucent, i.e., it has a transmittance of less than 50% at a wavelength of 600 nm, for example as measured using a Lambda 40 UV-visible spectrometer.

[0193] All percentages, parts and ratios herein are based on the total weight of the compositions of the present disclosure, unless otherwise indicated.

[0194] All ranges and values ​​disclosed in the specification 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. Furthermore, all ranges provided are intended to include each specific range within the given ranges, as well as a combination of subranges therein. Thus, a range of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as subranges such as 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc.

[0195] Except in working examples, or unless otherwise indicated, all numbers expressing amounts of ingredients and / or reaction conditions are understood to be modified in all circumstances by the term "about", meaning to within + / - 5% of the number indicated.

[0196] As used herein, the term "at least one" is interchangeable with "one or more" and therefore includes individual components as well as mixtures / combinations.

[0197] The term "substantially free" or "essentially free" as used herein means that less than about 5% 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 2% by weight, less than about 1% by weight, less than about 0.5% by weight, less than about 0.1% by weight, less than about 0.01% by weight, or none of the specified material.

[0198] The term "active ingredient," as used herein with respect to the percentage amount of an ingredient or raw material, refers to 100% of the activity of the ingredient or raw material.

[0199] “Cosmetically acceptable” means that the article in question is compatible with a keratinous substrate such as skin and hair. For example, a “cosmetically acceptable carrier” means a carrier compatible with a keratinous substrate such as skin and hair.

[0200] Throughout the disclosure, the phrase "a combination 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 combination thereof." The phrase "a combination thereof" does not require that the mixture 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 two or more of the elements A, B, C, D, E, and F may 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 combination of two or more of A, B, C, D, E, and F."

[0201] Similarly, the expression "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 combination 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 combination 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.

[0202] Salts referred to throughout the disclosure may include salts having a counterion such as an alkali metal, alkaline earth metal, or ammonium counterion. This list of counterions is not, however, limiting.

[0203] Some of the compounds discussed throughout the disclosure may be present as a salt in the composition or may be added to the composition as a salt (and dissociate in the composition). Thus, all compounds and amounts of compounds refer to both the salt form of the compound and the dissociated form of the compound. In other words, even if the phrase "a salt thereof" is not specifically or expressly stated with respect to ingredients capable of forming salts or available as salts, it is understood that the salt form of the compound is included.

[0204] The expression "included" for a concentration range means that the limits of this range are included in the defined interval.

[0205] “Volatile,” as used herein, means having a flash point less than about 100°C.

[0206] “Non-volatile,” as used herein, means having a flash point greater than about 100°C.

[0207] The term "polymers," as defined herein, includes homopolymers and copolymers formed from at least two different types of monomers.

[0208] The term "INCI" is an abbreviation for International Nomenclature of Cosmetic Ingredients, which is a system of names provided by the Personal Care Products Council's International Nomenclature Committee to describe the ingredients of personal care products.

[0209] As used herein, all ranges provided are intended to include each specific range within the given ranges, as well as a combination of sub-ranges therein. Thus, a range of 1-5 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.

[0210] All components and elements positively presented in this disclosure may be negatively excluded from the claims. In other words, the compositions of the present disclosure may be free or substantially free of all components and elements positively recited throughout this disclosure.

[0211] Some of the various categories of components identified may overlap. In such cases where an overlap may exist and the composition includes both components (or the composition includes more than two overlapping components), an overlapping compound or ingredient does not represent more than one component. For example, if a polyacrylate falls within the description of a thickening polymer and the description of a film-forming polymer, the specifically recited polyacrylate is considered to be only the thickening polymer or only the film-forming polymer. A specific polyacrylate cannot be simultaneously interpreted as a thickening polymer and a film-forming polymer, for example, when the claims disclose both a thickening polymer and a film-forming polymer (even though the polyacrylate can function as both a thickening polymer and a film-forming polymer).In other words, a single compound or ingredient cannot simultaneously perform the function of two different components of a claimed composition.
