Description

Title of the invention: Compositions and processes for hair SCOPE OF DISCLOSURE

[0001] This disclosure relates to compositions and processes for the treatment, care and / or revitalization of keratinous fibers, such as hair. CONTEXT

[0002] Many consumers wish to use cosmetic and care compositions that enhance the appearance of keratinous substrates such as 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. However, 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, dyeing, heat, nutrition, etc. Even cleansing products can strip the hair of its natural oils, causing dryness, which can lead to a dull appearance and split ends.

[0003] Chemical treatments include, for example, bleaching products, hair coloring, perms, perming products, and straightening treatments. These chemical treatments change the appearance of hair by altering its physical structure, inevitably causing some degree of damage. Environmental factors, such as salt water, sunlight, and heat, are also known to damage hair. Damaged hair is characterized by unnatural changes in the protein structure of individual hair strands or shafts. The damage results in split ends, dry, straw-like hair, hair that breaks easily, and hair that is frizzy and difficult to style. Because the visible part of the hair is dead, it cannot regenerate itself.Many over-the-counter and salon treatments claim to repair damaged hair. These include conditioners, hot oil treatments, hydrolyzed proteins, vitamin formulations, and extracts of exotic fruits, leaves, or roots. However, these treatments offer only limited improvement to the hair. Therefore, it is advisable to use hair repair technologies that restore the hair's natural properties.

[0004] The popularity and use of oils for treating dry hair have increased due to their effectiveness and simplicity. Oils commonly Oils used include olive oil, mineral oil, avocado oil, apricot kernel oil, rice bran oil, and coconut oil. However, these treatments can leave hair feeling greasy. Furthermore, the effects are not usually seen after several hours (e.g., 8 hours) of treatment, and multiple treatments are usually required, making the process time-consuming and laborious.

[0005] In addition to improving frizz control and smooth texture, consumers with curly or wavy hair have a particular need for hair treatments that provide good curl definition without weighing the hair down. Thus, there is always a need to offer improved manageability for both wet hair (e.g., improved combability and smooth texture when wet) and dry hair (e.g., improved hair alignment, reduced unwanted volume (including frizz reduction), while simultaneously increasing smooth texture and a feeling of hydration). Beyond providing such conditioning and conditioning benefits, there is also a need to develop hair care products that can provide other benefits simultaneously, such as improved manageability, volume, hold, and, for consumers with curly, wavy, or coily hair, curl definition.

Fatty Esters

[0038] In some exemplary embodiments, the compositions according to the disclosure include at least one fatty ester. In some embodiments, the at least one fatty ester is of vegetable and / or organic origin.

[0039] In one embodiment, at least one fatty ester is a liquid ester of saturated or unsaturated, linear or CrC26 branched aliphatic mono- or poly-acids and of saturated or unsaturated, linear or branched aliphatic mono- or poly-alcohols branched in Ci-C26, the total number of carbon atoms of the esters being greater than or equal to 10. In certain embodiments, where at least one fatty ester is a monoalcohol ester, at least one of the alcohol or acid from which the esters of the invention are derived is branched.

[0040] Among the monoesters of monoacids and monoalcohols, ethyl palmitate, isopropyl palmitate, alkyl myristates such as isopropyl myristate or ethyl myristate, isocetyl stearate, 2-ethylhexyl isononanoate, isononyl isononanoate, isodecyl neopentanoate, isostearyl neopentanoate, and mixtures thereof.

[0041] Esters of dicarboxylic or tricarboxylic acids in C4-C22 and of alcohols in Ci-C22, and esters of monocarboxylic, dicarboxylic or tricarboxylic acids and non-sugar dihydroxy, trihydroxy, tetrahydroxy or pentahydroxy alcohols in C4-C26, can also be used.

[0042] Examples include: diethyl sebacate, diisopropyl sebacate, bis(2-ethylhexyl) sebacate, diisopropyl adipate, di-n-propyl adipate, dioctyl adipate, bis(2-ethylhexyl) adipate, diisostearyl adipate, bis(2-ethylhexyl) maleate, triisopropyl citrate, triisocetyl citrate, trii-sostearyl citrate, glyceryl trilactate, glyceryl trioctanoate, trioctyldodecyl citrate, trioleyl citrate, neopentyl glycol diheptanoate and diethylene glycol diisononanoate; and mixtures thereof.

[0043] The composition may also include, as a fatty acid ester, sugar esters and diesters of C6-C30 fatty acids and preferably of C12-C22 fatty acids. It is recalled that the term "sugar" refers to compounds based on oxygen-bearing hydrocarbons containing several alcohol functional groups, with or without aldehyde or ketone functional groups, and comprising at least four carbon atoms. These sugars may be monosaccharides, oligosaccharides, or polysaccharides.

[0044] Suitable sugars may be cited, for example, sucrose, glucose, galactose, ribose, fucose, maltose, fructose, mannose, arabinose, xylose, lactose and their derivatives, in particular alkyl derivatives, such as methyl derivatives, for example methylglucose, and mixtures thereof.

[0045] Sugar and fatty acid esters can be selected in particular from the group of esters or mixtures of sugar esters described above and saturated or unsaturated fatty acids, linear or branched in C6-C30 and in some embodiments fatty acids in C12-C22. If they are unsaturated, these compounds can comprise one to three conjugated or non-conjugated carbon-carbon double bonds.

[0046] Esters according to this variant of form can also be selected from mono-, di-, tri- and tetraesters, polyesters, and mixtures thereof. These esters can be, for example, oleates, laurates, palmitates, myristates, behenates, Cocoates, stearates, linoleates, linolenates, caprates, arachidonates, or mixtures thereof, such as, in particular, mixed oleate / palmitate, oleate / stearate, or palmitate / stearate esters, are used. More specifically, mono- and diesters are employed, and in particular, mono- or dioleate, -stearate, -behenate, -oleate / palmitate, -linoleate, -linolenate, or -oleate / stearate of sucrose, glucose, or methylglucose. For example, the product sold under the name "Date® DO" by Amerchol is a methylglucose dioleate.

[0047] Finally, natural or synthetic esters of monoacids, diacids or triacids with glycerol can also be used. Among these, vegetable oils can be mentioned. Examples of oils of vegetable origin or synthetic triglycerides that can be used in the composition of the invention as liquid fatty substances include: triglyceride oils of vegetable or synthetic origin, such as liquid fatty acid triglycerides containing 6 to 30 carbon atoms, for example, heptanoic or octanoic acid triglycerides, or alternatively, for example, sunflower oil, corn oil, soybean oil, cucurbit oil, grapeseed oil, sesame oil, hazelnut oil, apricot oil, macadamia oil, amla oil, castor oil, avocado oil, camellia oil, camelina oil, olive oil, caprylic / capric acid triglycerides,for example those sold by the company Stéarineries Dubois or those sold under the names "Miglyol® 810", "Miglyol® 812", and "Miglyol® 818", by the Dynamit Nobel Company, jojoba oil, rapeseed oil, coconut oil, wheat germ oil, sweet almond oil, safflower oil, candlenut oil, tamanu oil, babassu oil, pracaxi oil, shea butter oil, and mixtures thereof.

[0048] In certain embodiments, liquid fatty esters derived from monoalcohols or triglycerides of vegetable origin can be used as fatty esters according to the invention.

[0049] According to one embodiment, the fatty esters are selected from hydrocarbon-based oils comprising more than 6 carbon atoms, such as liquid paraffin; liquid petroleum jelly; esters of Ci-C26 aliphatic monoacids and Ci-C26 aliphatic monoalcohols, these esters having a total number of carbon atoms greater than or equal to 10, in particular isopropyl myristate and isononyl isononanoate; vegetable oils, in particular coconut oil, shea butter oil, and olive oil; and mixtures thereof.

[0050] The total amount of at least one fatty ester may vary, but typically ranges from about 0.001% to about 10%, such as from about 0.01% to about 5%, or from about 0.1% to about 3%, or from about 1% to about 2% by weight of the total composition. For example, the total amount of at least one fatty ester may ranging from approximately 0.01% to approximately 10%, from approximately 0.01% to approximately 9%, from approximately 0.01% to approximately 8%, from approximately 0.01% to approximately 7%, from approximately 0.01% to approximately 6%, from approximately 0.01% to approximately 5%, from approximately 0.01% to approximately 4%, from approximately 0.01% to approximately 3%, from approximately 0.01% to approximately 2%, from approximately 0.01% to approximately 1%, from approximately 0.05% to approximately 10%, from approximately 0.05% to approximately 9%, from approximately 0.05% to approximately 8%, from approximately 0.05% to approximately 7%, from approximately 0.05% to approximately 6%, from approximately 0.05% to approximately 5%, from approximately 0.05% to approximately 4%, from approximately 0.05% to approximately 3%, from approximately 0.05% to approximately 2%, from approximately 0.05% to approximately 1%, from approximately 0.1% to approximately 10%, from approximately 0.1% to approximately 9%, from approximately 0.1% to approximately 8%, from approximately 0.1% to approximately 7%, from approximately 0.1% to approximately 6%, from approximately 0.1% to approximately 5%, from approximately 0.1% to approximately 4%, from approximately 0.1% to approximately 3%, from approximately 0.1% to approximately 2%, from approximately 0.1% to approximately 1%, from approximately 0.5% to approximately 10%from about 0.5% to about 9%, from about 0.5% to about 8%, from about 0.5% to about 7%, from about 0.5% to about 6%, from about 0.5% to about 5%, from about 0.5% to about 4%, from about 0.5% to about 3%, from about 0.5% to about 2%, from about 0.5% to about 1.5%, from about 0.5% to about 1%, from about 1% to about 10%, from about 1% to about 9%, from about 1% to about 8%, from about 1% to about 7%, from about 1% to about 6%, from about 1% to about 5%, from about 1% to about 4%, from about 1% to about 3% by weight, from about 1% to about 2%, from about 1% to about 1.5%, including all intermediate ranges and sub-ranges, relative to the total weight of the composition.

For example, the composition may include water in an amount of up to about 99%, such as, for example, an amount ranging from about 50 to about 95% or from about 60% to about 90%, by weight relative to the weight of the composition.

[0053] In some embodiments, the weight ratio between the total amount of the first and second cationic compounds and the total amount of branched fatty alcohol ranges from approximately 1:15 to approximately 15:1, such as from approximately 1:10 to approximately 10:1, from approximately 1:5 to approximately 5:1, or from approximately 1:3 to approximately 3:1. In other embodiments, the weight ratio between the total amount of the first and second cationic compounds and the total amount of fatty esters ranges from approximately 1:15 to approximately 15:1, such as from approximately 1:10 to approximately 10:1, from approximately 1:5 to approximately 5:1, or from approximately 1:3 to approximately 3:1. Additional components

[0054] The compositions according to the disclosure may also include additives selected from pearlescent agents, dyes or pigments, perfumes, mineral, vegetable or synthetic oils, waxes, vitamins, proteins, including ceramides, UV filtering agents, free radical scavengers, anti-dandruff agents, anti-hair loss agents, hair regenerators, preservatives, or mixtures thereof. Those skilled in the art shall take care to select the optional additives and their quantity so as not to impair the properties of the compositions of this disclosure.

[0055] The compositions of certain embodiments may include stabilizers, for example sodium chloride, magnesium dichloride or magnesium sulfate.

[0056] The compositions according to the disclosure may further include cosmetic adjuvants selected from perfumes, pigments, chelating agents, softeners, antioxidants, opacifiers, stabilizers, moisturizing agents, vitamins, bactericides, preservatives, polymers, thickening agents or any other ingredient commonly used in cosmetics for this type of application.

[0057] In various embodiments, these additives are generally present in an amount of up to about 40% by weight of active material relative to the total weight of the composition, such as up to about 30%, up to about 20%, up to about 15%, up to about 10%, up to about 5%, such as from 0.01% to 30%.

[0058] If desired, a person skilled in the art may select the additives or their quantities in order to maintain the natural or organic properties of the compositions.

[0059] In some embodiments, the compositions are free or substantially free of secondary gums, silicones, and / or synthetic polymers. For example, the compositions include less than approximately 3%, less than approximately 2%, less of approximately 1%, or less than approximately 0.5% of secondary gums, silicones, and / or synthetic polymers, and in some embodiments do not include secondary gums, silicones, and / or synthetic polymers. In some embodiments, however, the compositions may include secondary gums, silicones, and / or synthetic polymers. Non-limiting examples of silicones include amine-functionalized silicones (e.g., amodimethicone), dimethicone, bis-aminopropyl dimethicone, and trimethyl silylamodimethicone.

[0060] In certain embodiments, at least 85%, at least 88%, at least 90%, or at least 95% of the disclosed materials used in the compositions are of plant origin. In one example of an embodiment, the compositions according to the disclosure demonstrate desirable cosmetic properties while comprising primarily, such as at least approximately 90%, ingredients of natural origin.

[0061] The compositions described herein may be in any suitable physical form. Suitable forms include, but are not limited to, low- to moderate-viscosity liquids, lotions, milks, gels, creams, pastes, clays, conditioners, masks, and the like. In various embodiments, the compositions may have a lamellar phase structure.

[0062] Compositions may be packaged in various different containers, such as, for example, a ready-to-use container. Non-limiting examples of useful packaging include tubes, jars, caps, unit-dose packs, and bottles, including squeezable tubes and bottles. In some cases, the packaging is a tube, such as a tube with two compartments, or double tubes, each forming a separate compartment. Each compartment may contain a different composition. For example, one tube or compartment may contain a composition according to this disclosure, and the other tube may contain a composition to be used with the composition, for example, a shampoo or hair repair or treatment product.

[0063] The pH of the compositions according to this disclosure will vary. Nevertheless, in various embodiments, the hair treatment compositions have a pH of about 3 to about 10. In other embodiments, the hair treatment composition has a pH of about 3 to about 8.5, about 3 to about 8, about 3.5 to about 7, about 3.5 to about 6, about 3.5 to about 5, about 3.5 to about 4.5 or about 3.5 to about 4.

[0064] The compositions of this disclosure are unique in their ability to provide hair with enhanced conditioning properties, including, but not limited to, suppleness, softness, hydration, conditioning, detangling, smooth texture, manageability, and frizz control while maintaining body, volume, and a Fullness, movement, bounce, and manageability are all important considerations. Accordingly, this disclosure relates to hair treatment processes, for example, to improve hair manageability and provide a smooth texture. More specifically, the compositions may be used in processes to condition hair, improve combability and detangling, and provide a smooth texture, etc. II. Processes

[0065] The processes according to the disclosure include treating keratin fibers with the compositions described herein. The processes generally include applying any one of the disclosed compositions to the hair.

[0066] By way of example, the methods may include using the compositions as a conditioner, as part of a shampoo (e.g., a conditioning shampoo), as a pre-treatment, or as a rinse-off mask treatment. In one embodiment, the composition is a wash-in conditioner. Alternatively, in some embodiments, the hair treatment compositions may be used as a leave-in product. The compositions are applied to wet or damp hair and may remain on the hair indefinitely; that is, the hair treatment composition is not removed or rinsed from the hair before drying or styling.

[0067] Hair treatment processes according to the disclosure may include applying a composition according to the disclosure to the hair (damp, wet, or dry hair), leaving the composition on the hair for a desired duration, and optionally rinsing the composition from the hair. The composition may be applied to the hair before, during, or after other hair compositions (e.g., shampoo, conditioner, mask, cream, lotion, gel, etc.).

[0068] The composition can be left on the hair for a period of time, for example from about a few seconds (e.g. about 10, 20 or 30 seconds) to about 1, 2, 3, 5, 10, 20 or 30 minutes, or longer. If desired, the hair can be heated while the composition is on the hair. III. Necessary

[0069] The hair compositions of this disclosure may be incorporated into a kit. For example, kits may include at least one conditioner composition according to this disclosure and one or more additional compositions, for example, a shampoo, a hair repair product, or a hair treatment, etc. The different compositions are contained separately in the kits. In some cases, the kits include one or more additional compositions. The kits may also include one or more conditioning compositions as described in this disclosure, a shampoo, and a hair repair or treatment product, all of which are contained separately. Instructions, mixing components, brushes, gloves, measuring tools, etc., may optionally be included in the kits.

[0070] It should be understood that all definitions herein are provided only for the purposes of this disclosure.

[0071] As used herein, the terms "comprising," "having," and "including" (or "comprise," "having," and "include") are used in their broad, non-limiting sense. The expression "consisting essentially of" limits the scope of a claim to the specified materials or steps and to those that do not materially affect the fundamental and innovative features of the compositions.

[0072] The singular forms "un", "une", "le", "la" and "au moins un(e)" are understood to include both the plural and the singular.

[0073] Thus, the expression "one of their mixtures" also refers to "their mixtures." Throughout the disclosure, if the expression "one of their mixtures" 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 one of their mixtures," the expression "one of their mixtures" 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 mixture of two or more of A, B, C, D, E, and F may be included. In other words, it is equivalent to the formulation "one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture of two or more of A, B, C, D, E, and F."

[0074] Similarly, the expression "one of their salts" also refers to "their salts". Thus, when the disclosure refers to "an item selected from the group consisting of A, B, C, D, E, F, one of their salts, or mixtures thereof", it indicates that one or more of A, B, C, D and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included, or a mixture of any two of A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included.

[0075] The 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, however, is not exhaustive.

[0076] Some of the compounds mentioned throughout the disclosure may be present in the form of a salt in the composition or be added to the composition in the form of a salt. form of a salt (and dissociate within the composition). Thus, all compounds and quantities 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 "one of their salts" is not specifically or expressly stated with respect to ingredients that can form salts or are available as salts, it is understood that the salt form of the compound is included.

[0077] The expression "one or more" means "at least one" and therefore includes individual components as well as mixtures / combinations.

[0078] All ranges and quantities stated in this document are intended to include subranges and quantities using any disclosed point as a boundary. Thus, a range of "1% to 10%, such as 2% to 8%, such as 3% to 5%" is intended to encompass ranges of "1% to 8%", "1% to 5%", "2% to 10%", and so on. All numbers, quantities, ranges, etc., are intended to be modified by the term "approximately", whether or not it is expressly stated. Similarly, a given range of "approximately 1% to 10%" is intended to have its boundaries of both 1% and 10% modified by the term "approximately". The term "approximately" is used in this document to indicate a difference of up to + / - 10% from the stated number, such as + / - 9%, + / - 8%, + / - 7%, + / - 6%, + / - 5%, + / - 4%, + / - 3%, + / - 2%, or + / - 1%.Similarly, all range boundaries are understood as being disclosed individually, such that, for example, a range of 1:2 to 2:1 is understood as disclosing a ratio of 1:2 and 2:1.

[0079] Unless otherwise stated, all percentages here are by weight, relative to the weight of the total composition.

[0080] The term “surfactants” includes salts of surfactants even if they are not explicitly stated.

[0081] As used herein, the expressions "substantially free" or "essentially free" mean that the specific substance may be present in small quantities that do not materially affect the basic and innovative characteristics of the compositions as disclosed. For example, there may be less than 2% by weight of a specific substance added to a composition, relative to the total weight of the compositions (provided that an amount less than 2% by weight does not materially affect the basic and innovative characteristics of the compositions as disclosed). Similarly, the compositions may include less than 2%, less than 1.5%, less than 1%, less than 0.5%, less than 0.1%, less than 0.05%, or less than 0.01%, or none of the specified substances.Furthermore, all components presented positively in this disclosure may be excluded negatively from the claims, for example, a claimed composition may be "free", "essentially free" (or "substantially free". exempt”) from one or more components that are presented in a positive light in this disclosure.

[0082] The expression "substantially free" or "essentially free" as used here may also mean that the specific material is not added to the composition, but that it may still be present in a raw material included in the composition.

[0083] The term "synthetic" refers to a material that is not of natural origin. The term "natural" refers to a material of natural origin, such as derived from plants, which also cannot be subsequently modified chemically or physically.

[0084] As used herein, the term “organic” refers to a material that is produced substantially without or essentially without the use of synthetic materials. The expressions “substantially without” or “essentially without” as used herein mean that the specific material may be used in a manufacturing process in small quantities that do not significantly affect the fundamental and innovative characteristics of the compositions according to the disclosure. The expressions “substantially without” or “essentially without” as used herein may also mean that the specific material is not used in a manufacturing process, but that it may still be present in a raw material included in the composition.

[0085] A “cosmetic composition” encompasses many types of compositions for application to keratinous materials such as skin or hair, for example, hair lotions, hair creams, hair cream gels, hair conditioners, hair masks, etc., which can be used as treatments or leave-in or rinse-out products.

[0086] The term "rinse-off" as used here indicates that the composition is used in a context where the composition is ultimately rinsed or washed off the treated surface (e.g., skin, hair, or hard surfaces) after or during application of the product. These rinse-off compositions should be distinguished from compositions referred to as "leave-in" compositions. For example, a rinse-off composition is applied to the hair, optionally left on the hair for a short period (e.g., from a few seconds up to about 5, 10, or 15 minutes), and is then rinsed from the hair before styling.

[0087] The compositions described throughout this disclosure may be a "leave-in" composition. A "leave-in" composition refers to a composition that is applied to the 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; that is, it is not removed from the hair before styling.

[0088] A "lamellar phase" generally refers to the arrangement of long-chain, polar-headed, non-polar-tailed molecules in a bulk polar liquid environment (i.e., hair water), in the form of bilayer sheets separated by a bulk liquid.

[0089] 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 UV-visible Lambda 40 spectrometer. 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 UV-visible Lambda 40 spectrometer. The term "clear" is interchangeable with the term "transparent" for the purposes of this disclosure. A person can typically see through a transparent composition, for example, and read the text on the other side of a clear glass or clear plastic bottle containing the composition.

[0090] 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 is unlikely to be able to 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; however, motion and structure can normally be identified.

[0091] The term "opaque" in relation to an opaque composition indicates that the composition is not transparent or translucent, that is to say, it has a transmittance of less than 50% at a wavelength of 600 nm, for example measured using a Lambda 40 UV-visible spectrometer.

[0092] The term "cosmetically acceptable" means that the article in question is compatible with a keratinous substrate such as skin and hair. For example, a "cosmetically acceptable vector" means a vector compatible with a keratinous substrate such as skin and hair.

[0093] The term "polymers", as defined herein, includes homopolymers and copolymers formed from at least two different types of monomers.

[0094] The term “INCI” is an abbreviation for International Nomenclature of Cosmetic Ingredients, which is a system of names provided by the International Nomenclature Committee of the Personal Care Products Council to describe the ingredients of personal care products.

[0095] All components and elements positively presented in this statement may be negatively excluded from the claims. In other words, the compositions of this disclosure may be free or substantially free of all the components and elements positively cited throughout this disclosure.

[0096] Some of the various identified component categories 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. In other words, a single compound or ingredient cannot simultaneously have the function of two different components of a claimed composition.

[0097] It will be apparent to those skilled in the art that various modifications and variations can be made to the compositions and processes according to the disclosure without departing from the spirit or scope of the disclosure. Therefore, it is intended that the disclosure in the description above and in the examples given below covers such modifications and variations and their equivalents, and should be interpreted in an illustrative and not limiting sense.

[0112] Example 2 - General procedure for testing the performance attributes of the invention on wavy hair

[0113] The following tests were carried out on 11 samples of hair strands (CP4) made from bleached European curly hair (approximately 2.7 g / strand by weight and 20 cm / strand by length when straight).

[0114] On each strand sample, the shampoo from Table 2 was applied, lathered into the curls for approximately 10 to 15 seconds, and then rinsed with water. Each strand sample was then treated with one of the conditioner formulations shown in Table 1 and Table 3A. After massaging one of the conditioner formulations into the curls of a strand for approximately 10 to 15 seconds, the conditioner formulation was rinsed with water. Excess water was removed from the strand samples using a towel. For each of the 4 samples of For each of the 11 strand samples (on which Inventive Conditioner #1 and Comparative Conditioner #1, #2, and #3 were applied, respectively), the following performance attributes were measured by three laboratory experts (N = 3): wet combability and wet smoothness. The metrics were based on their average rating score, as shown in Table 4A. The strand samples were air-dried under ambient conditions before further observations. For each of the 11 strand samples, the following performance attributes were then measured by three laboratory experts (N = 3): dry smoothness, dry moisture feel, dry curl definition, and dry frizz control. The metrics were based on their average rating score, as shown in Tables 4A and 4B.Photographs of dried hair strand samples (onto which inventive formulations #1 and comparative conditioners #1, #2 and #3 were applied, respectively) are shown in [Fig.1], and photographs of dried hair strand samples (onto which inventive conditioner formulations #1 to #5 and comparative conditioner formulations #4 to #6 were applied, respectively) are shown in [Fig.2].
