[0001] REFERENCE TO RELATED APPLICATIONS This application claims priority to U.S. Provisional Patent Application U.S. Serial No. 63 / 323,608, filed March 25, 2022.

[0002] FIELD OF THEINVENTION The present invention relates to hair treatment compositions containing ingredients that provide repair to damaged keratinous fibers, and methods for the application of the compositions. [Background technology]

[0003] 2. Background of the Invention Keratin fibers, particularly human hair, are damaged by everyday activities such as brushing and combing, external influences such as sunlight and pollution, and oxidative and / or reductive treatments such as dyeing, bleaching, or perming. The damage caused by these activities includes the removal of F-layer fatty acids, the scission of disulfide bonds in keratin proteins, and the erosion of keratin protein material at the surface of the hair fiber cuticle. The damage tends to roughen the hair fiber surface in a manner similar to how a file roughens wood. Rough hair strands lack smoothness, tend to become unkempt, and are unmanageable. Hair care goals have included attempts to reverse these trends.

[0004] One such attempt includes hair care and repair agents, such as hair cortex repair formulations and related methods. It is believed that damage to the hair cortex can lead to unraveling of cortical protein bundles, resulting in irregularities and roughness. One possible answer included the use of maleic acid molecules and cysteine ​​thiol bonds to recombine broken disulfide bonds in the hair cortex. See WO 2015 / 017768 A1. Another possible answer included a method of reconstructing the hair fiber cortex with cysteine ​​and at least one dicarboxylic acid. See WO 2005 / 115314.

[0005] However, these methods are only partially successful. They do not address the erosion of cuticle, the subsurface and surface decomposition of keratin protein. Therefore, there is still a need to provide a composition that provides excellent hair cuticle repair, since this remains one of the major concerns of consumers' hair. A further need is to improve the integrity and health of hair, and provide gloss, suppleness, smooth hair feel, and good detangling properties. Summary of the Invention

[0006] The present invention relates to a hair treatment composition and corresponding method for treating the cuticle of keratin fibers, particularly the cuticle of anagen human hair damaged by routine and chemical treatments. The hair treatment composition embodiments deliver ingredients to protect and repair the damaged cuticle of keratin fibers, such as human anagen hair strands. The composition ingredients can effectively and significantly repair the internal bonds of broken keratin proteins, smooth the roughness of the hair strand, lubricate the hair strand, and fuse the ends of split hairs, i.e., frizz. The composition ingredients provide treatment of the hair strands without causing weight or greasiness of the hair strands. Furthermore, the present invention provides improved frizz prevention, improved shine, improved dry feel, and prevention of oily and dirty hair feel.

[0019] The term "may" in the context of this application means "is permitted to" or "is able to" and is synonymous with the term "can." As used herein, the term "may" does not imply possibility or chance.

[0020] The term "and / or" in the context of this application means one or the other, or both. For example, an aqueous solution of A and / or B means an aqueous solution of A alone, an aqueous solution of B alone, and an aqueous solution of A and B in combination.

[0021] The term "about" is understood to mean plus or minus ten percent of the recited number, number, or range of numbers.

[0022] The term "about 0% by weight" is understood to mean that zero (0) is not present in the substance, compound or material to which it refers, but rather that it is present in negligible but detectable amounts, assuming that detectability can be determined on a parts per million basis.

[0023] References throughout this specification to "an embodiment," "one embodiment," or "preferred embodiment," or "more preferred embodiment," or "most preferred embodiment" refer to features of any one or more elements and may be used in connection with different elements of the invention. A particular feature, structure, or characteristic described in connection with one embodiment is not necessarily the same as another feature, structure, or characteristic of another embodiment of the presently claimed invention. Thus, the appearance of the phrases "in one embodiment," "in one embodiment," or "in a preferred embodiment" in various places throughout this specification may not necessarily all refer to the same embodiment, but may refer to different embodiments of the presently claimed invention. Furthermore, features, structures, or characteristics in one or more embodiments may be combined in any suitable manner, as would be apparent to one of ordinary skill in the art from this disclosure. Furthermore, although some embodiments described herein include some features and not other features included in other embodiments, combinations of features of different embodiments are meant to form different embodiments within the scope of the present subject matter and as would be understood by one of ordinary skill in the art. For example, in the appended claims, any of the claimed embodiments may be used in any combination.

[0024] The term "user" or "customer" refers to the person who prepares the hair treatment composition. The user may be, for example, a professional hair stylist working in a beauty salon, and may be different from the subject to whom the composition is applied to the hair, or the user may be the same as the subject to whom the composition is applied to the hair.

[0025] The term "fatty" in the context of an organic compound means an alkyl or alkenyl group of at least 8 carbons, or an alkane or alkene, which may have up to about 60 carbons, preferably from about 10 to about 30 carbons, and may be linear or branched with 1 to 8 C1-C6 alkyl groups. A branched alkyl group counts as an extra carbon relative to the carbon count of the backbone of the fatty alkyl group, alkenyl group, alkane or alkene. The number of olefinic unsaturations in the fatty alkenyl or alkene may range from 1 to 8 sites of unsaturation. The sites of unsaturation may be non-conjugated, partially conjugated, or fully conjugated. This definition of "fatty" is understood to describe all fatty alkyl or alkenyl groups, or alkanes and alkenes described herein. When one or more descriptions of carbon number, branching, and unsaturation are included in a particular example of a fatty alkyl or alkenyl group, or alkane or alkene, those specific descriptions apply.

[0026] Alkyl or alkenyl groups, alkanes or alkenes, or organic compounds containing alkyl or alkenyl groups that are not characterized as "fatty" in the context of this invention can have a carbon number in the alkyl or alkenyl group from 1 to about 10 carbons, preferably from 1 to about 8 carbons, and the alkyl or alkenyl group can be linear or branched.

[0027] The terms "unsaturated" and "unsaturated" in the context of an organic compound mean at least one olefinic double bond, and can include multiple olefinic double bonds, up to about eight olefinic unsaturations.

[0028] The term "stand-alone" in the context of a conditioner or mask means that the conditioner or mask is formulated and used separately from other compositions or formulations developed for use on hair, such as, but not limited to, shampoos. Thus, a typical stand-alone conditioner, stand-alone leave-on conditioner, stand-alone rinse-off conditioner, and / or stand-alone mask is not a component of a shampoo, a hair cleansing composition, a hair oxidation dye composition, a hair bleaching composition, and / or other compositions for use on hair. These conditioner embodiments provide conditioning properties, including, but not limited to, smoothing, softening, and conditioning the hair to provide shine, softness, smoothness, ease of detangling, free flow, bouffancy, ease of combing, and non-greasy, non-weightless hair.

[0029] The term "leave-on" in the context of conditioners means that the conditioner components are formulated to provide the above-mentioned conditioning properties to the hair without excessive wetting of the hair upon application of the conditioner. Leave-on conditioners are formulated to have variable viscosities depending on whether the leave-on conditioner is formulated as an aerosol, non-aerosol spray, lotion, cream, mousse, gel or paste. These formulations can range from liquid like water to thick like gel or mousse by adjusting the weight percent concentration of the components and vehicle. Thorough distribution and coverage of the conditioner components throughout the hair can be achieved by rubbing, massaging, smearing, tapping with fingers and / or similar means. The vehicle formulation is formulated to allow evaporation by brushing and / or combing the hair. Leave-on stand-alone conditioners according to the present invention can optionally contain less highly hydrophobic (lipophilic) lipid components such as hydrocarbons and fatty acid esters, little or no anionic surfactants, and moderately hydrophobic lipid components such as fatty alcohols and cationic surfactants, and moderate to slightly higher amounts of nonionic surfactants, relative to typical stand-alone and rinse-off stand-alone conditioners.

[0030] The terms "rinse-off" and "general" in the context of conditioners mean that the weight percentages of the conditioner's components are formulated to provide a variable viscosity, depending on whether the conditioner is formulated as a spray, cream, lotion, gel, mousse, paste, or similar fluid to gel-like composition, which may, but need not necessarily, be thixotropic. Rinse-off and general conditioners can be applied to wet hair after shampooing, and the hair so treated can be rinsed with room to warm water. General conditioners according to the present invention may optionally be formulated with relevant concentrations of anionic and cationic surfactants capable of forming coacervates during rinsing. Rinsing removes excess conditioner while leaving at least a portion of the conditioner ingredients, not limited to coacervates, on the hair. Rinse-off conditioners and general conditioners according to the present invention can optionally contain more highly hydrophobic lipid components such as hydrocarbons and fatty acid esters, and more moderately hydrophobic lipid components such as fatty alcohols and cationic surfactants, as well as non-ionic surfactants.

[0031] The term "mask" in the context of the present invention means that the ingredients of the hair treatment composition are formulated to provide a cream, paste, or gel-like configuration with high concentrations of moisturizers, humectants, nutrients, first component and optional second component, and low to moderate concentrations of vehicle, relative to the concentrations of ingredients of the leave-on and rinse-off conditioner embodiments of the hair treatment composition. Masks are typically leave-on embodiments and may be left on the hair for a reasonable period of time and then briefly rinsed out, if desired.

[0032] When features or aspects of the invention are described in terms of a Markush group, one of skill in the art will recognize that the invention is also described in terms of the individual members or subgroups of members of the Markush group. For example, if X is described as being selected from the group consisting of methyl, ethyl, or propyl, then the claim or embodiment where X is methyl, the claim or embodiment where X is ethyl, and the claim or embodiment where X is propyl are fully described. Furthermore, when features or aspects of the invention are described in terms of a Markush group, one of skill in the art will recognize that the invention is also thereby described in terms of any combination of the individual members or subgroups of members of the Markush group. Thus, for example, if X is described as being selected from the group consisting of bromine, chlorine, and iodine, and Y is described as being selected from the group consisting of methyl, ethyl, and propyl, then the claim or embodiment where X is bromine and Y is methyl are fully described.

[0033] When the value of a variable that is necessarily an integer, such as the number of carbon atoms in an alkyl group or the number of substituents on a ring, is stated as a range, e.g., 0 to 4, what is meant is that the value can be any integer between 0 and 4, i.e., 0, 1, 2, 3, or 4. Similarly, values ​​expressed in range format should be interpreted flexibly as if each numerical value or subrange were explicitly stated, to include not only the numerical values ​​explicitly stated as the limits of the range, but also all individual numerical values ​​and subranges contained within the range. For example, the range "about 0.1% to about 5%" or "about 0.1% to about 5%" should be interpreted to include not only about 0.1% to about 5%, but also the individual values ​​(e.g., 1%, 2%, 3%, and 4%) and subranges within the stated range (e.g., 0.1% to 0.5%, 1.1% to 2.2%, 3.3% to 4.4%).

[0034] The term "anagen hair" as used herein means a hair strand that is directly connected to a hair follicle that is in either the anagen or telogen state. Atrichic hair is present in either of these states on the human head, and its hair follicle is associated with a sebaceous gland that secretes sebum and long-chain fatty acids substantially continuously onto the surface of the hair shaft. As the hair grows out of the follicle, the follicle becomes coated with the secreted sebum and long-chain fatty acids. The fatty acid coating is known as the f-layer and is tightly intertwined with the keratin protein at the hair shaft surface. Hair cut from a living human is no longer anagen hair.

[0035] Keratin fiber refers to hair on the human scalp, preferably hair strands in the anagen phase. Keratin fiber, also known as hair strand, is composed of cells forming an inner cortex as the core and a cuticle as the outer covering surrounding the cuticle. The chemical components of hair strands include proteins, polynucleic acids, amino acids, minerals, melanin, lipids such as fatty acids, fatty alcohols, triglycerides, phospholipids, cholesterol, and squalene. These components are organized as cells, fibrils, connective tissue, extracellular bonds, pigments, keratin, and related structures. The outer layer of the cuticle is organized as a sheath of overlapping flattened cells with a structure similar to palm bark or fish scales. The surface of the cuticle is smooth from root to tip and rough from tip to root, similar to fish scales. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0036] Detailed Description The present invention relates to a hair treatment composition for replenishing and adding ingredients and substances to damaged anagen hair.

[0071] The concentration range of dicarboxylic acid and fatty monocarboxylic acid follows the general relationship that the weight percent of the total weight of the composition is usually, but not always, greater for dicarboxylic acid than for fatty monocarboxylic acid. This weight percent is calculated based on the combined total weight of dicarboxylic acid and fatty monocarboxylic acid without other ingredients. The weight percent ratio of dicarboxylic acid to fatty monocarboxylic acid ranges from about 50:1 to about 1:10, preferably from about 30:1 to about 1:7.5, more preferably from about 30:1 to about 1:5, particularly more preferably from about 30:1 to about 1:3 or up to about 1:75, with exemplary weight ratios being 30:1, 20:1, 10:1, 6:1, 3:1, 1:1, 1:1.67, 1:2, 1:3, 1:5, and up to 1:10.

[0072] Each of these components also has an individual concentration range in weight percent based on 100% total composition weight, which includes at least the vehicle and all other components, such as the second component, if present.

[0073] The individual concentration ranges of the components of the first component follow the concentration relationships described above. The dicarboxylic acid can be present at about 0.01% to about 35% by weight, preferably about 0.1% to about 25% by weight, more preferably about 0.1% to about 20% by weight, and even more preferably about 0.1% to about 15% by weight. Exemplary concentrations of the dicarboxylic acid include 0.1, 0.5, 1.0, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, and 10% by weight, including all digital integrals between these values.

[0074] The fatty monocarboxylic acid can be present at about 0.01% to about 35% by weight, preferably about 0.015% to about 25% by weight. More preferably, it can be present at about 0.015% to about 20% by weight, and particularly preferably at about 0.015% to about 15% by weight. Exemplary concentrations of fatty carboxylic acid include 0.01, 0.015, 0.03, 0.1, 0.2, 0.5, 0.75, 1.0, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, and 10% by weight, including all digital integrals between these values.

[0075] Carboxylic acid embodiments of the first component may be present in the hair treatment composition as acids and / or as salts of the carboxylic acid groups, where the counter ions in the salts may be sodium, potassium and / or ammonium. The pH of the hair treatment composition may be adjusted using an acid or base and / or buffer, as described below. The pH adjustment may, but does not necessarily, convert at least a portion of the carboxylic acid groups of the carboxylic acid embodiments into salts and / or buffer salts.

[0076] Hair in the anagen phase can be damaged by wear and deterioration caused by perms, redox treatments, shampooing, cleansing and washing with anionic surfactants, brushing, combing, rubbing with towels, hats, caps, etc. These activities performed on anagen hair strands thin, break, fragment, split and otherwise damage the hair. This damage is believed to result from lifting of cellular scales on the surface of the cuticle of the hair strand and removal of lubricating substances from the scales. Lifting and de-lubrication allows for the breaking, detachment, fragmentation and disruption of inter-scale connections of fatty acids, phospholipids and disulfide bonds. Water, soaps, shampoos, anionic surfactants and similar solubilizing agents can penetrate the cuticle because the individual scales of the cuticle have been lifted. This penetration allows for dilution, solubilization and dispersion of lipids, fats, fatty acids and sebum that at least partially form fine connections between the lifted scales. This results in a weakening of the cuticle of the hair strand, resulting in breakage, fragmentation and splitting of the hair.

[0077] The above-described embodiments of the hair treatment composition according to the invention replace and reconstruct the inter-scale connections of the hair strands, cover the scale surfaces of the hair strands and close the inter-scale spaces resulting from lifting, which is believed to result in strengthening the hair strands and making the scales less susceptible to lifting. Strengthening can be measured by the ease of combing such treated hair strands.

[0078] Optional second component The first component of the hair treatment composition can be combined with an optional second component that includes any one or more of the lipophilic hydrocarbon and fatty acid ester components. Additional second components include, but are not limited to, one or more of the following: fatty alcohol components, cationic surfactant components, silicone components, cationic polymer components, nonionic surfactant components, preformed polymer components, emulsifier components, thickener components, colorant components, and other additive components.

These concentrations are based on the total weight of the entire composition including at least the medium, the first component, and the second component. The weight percentage ratio of the first component (the sum of the dicarboxylic acid and fatty monoacid) to the second component (the sum of all the second components) may range from about 20:1 to about 1:20, preferably from about 10:1 to about 1:10, more preferably from about 5:1 to about 1:5, especially from about 4:1 to about 1:4, and all ratios between these ranges.

If some of the components are highly hydrophobic, such as fatty alcohols, the preparation method includes forming an emulsion of the hydrophobic components and surfactants, such as cationic surfactants and nonionic surfactants, in the desired medium. The emulsion can be added slowly to a mixture of the hydrophilic components in the medium, and additional surfactants may be added to maintain the emulsified mixture. If the hydrophobic components are solids, they can be melted and mixed with a portion of the warmed medium in which the nonionic surfactants and the hydrophobic components are soluble, and / or an emulsion can be formed. The solution and / or emulsion can then be cooled and slowly added to a preformed solution of the hydrophilic component in the vehicle with vigorous stirring to maintain the solution and / or emulsion. If microparticles are included in the composition, they can be slowly added to the formed solution and / or emulsion as a mixture with the vehicle and suspending agent.

[0136] The shampoo for the unit container may also include conditioning agents such as, but not limited to, one or more of a cationic surfactant, a silicone and / or a cationic polymer, and an anti-dandruff agent.

[0137] The unit container of hair treatment composition may include a conventional stand-alone conditioner, a stand-alone leave-on conditioner or a stand-alone rinse-off conditioner.

[0138] How to apply The universal stand-alone conditioner, stand-alone leave-on conditioner, stand-alone rinse-off conditioner, and stand-alone mask embodiments of the hair treatment composition may be applied directly to the growing hair (human head hair), or the universal stand-alone conditioner or stand-alone rinse-off conditioner may be diluted with water or a combination of water and water-miscible alcohol and applied to the growing hair. After application, these embodiments of the treatment composition on the hair may be massaged and worked through the hair to distribute the embodiment throughout the hair. After a sufficient time has elapsed to achieve conditioning and / or further functions of the hair treatment composition on the hair, further treatment may be applied depending on the embodiment of the hair treatment composition, i.e., conditioner or mask, used. If the embodiment is a universal stand-alone conditioner, the hair may be optionally rinsed with water. If the hair treated with this embodiment is not rinsed, especially if the embodiment is diluted with water before its application to the hair or during bathing or showering, the hair can be toweled to remove excess conditioner and then dried as described below.If the embodiment is a stand-alone rinse-off conditioner, the hair can be rinsed with water and toweled to remove rinse water.In both of these treatment embodiments, the hair can then be optionally combed, and the conditioned hair can then be dried with cold or hot air.If the hair treatment composition is a leave-on conditioner or mask, the leave-on conditioner or mask can be applied to the entire hair, and then the hair can be combed and / or brushed and / or briefly toweled to remove any excess composition, and then allowed to dry naturally, preferably without the use of airflow.

[0139] One or more of the following may also form the second part of shampoo and conditioning regimen: a general stand-alone conditioner, a stand-alone leave-on conditioner, a stand-alone or rinse-off conditioner. This regimen is carried out using the above-mentioned kit consisting of separate containers of cleansing and washing composition (shampoo) and conditioner. This regimen includes a first step of shampooing hair with a cleansing and washing composition that contains sulfate and / or non-sulfate anionic surfactant, such as Wella Professionals Invigo® shampoo, Wella Professionals Fusion Intense Repair® shampoo, or Wella Professionals Elements Renewing® shampoo, followed by rinsing and optionally drying to dampness with a towel. The second part of the regimen is followed by the above-mentioned treatment process using one of the stand-alone conditioners.

[0140] Use of a stand-alone mask is not typically followed with a shampoo regimen, but may be applied after shampooing, rinsing and drying hair.

[0141] It is believed that the regimen procedure of using two unit kits for cleaning and conditioning provides better conditioning results than using a single shampoo composition that also contains conditioning agent.As discussed above, the anionic surfactant cleaning agent of the cleansing and cleaning composition such as shampoo removes natural oils, fatty acids and natural smoothing components from the hair surface.The conditioning agent such as fatty acids, cationic surfactants, etc. present in the single combined cleansing, cleaning and conditioning composition containing anionic surfactant cleaning agent and conditioning agent will mainly substantially disappear and / or remove the added conditioning agent from the hair surface when the shampoo composition is lathered on hair, rubbed, repeatedly diluted with water, rinsed, and / or especially when hair is subsequently washed and / or contacted with body soap and / or body wash during bathing and / or showering. Although conditioning shampoos may be formulated to generate and deposit anionic and cationic surfactant coacervate conditioners on the hair during the shampooing process, the coacervates can be dissolved and / or removed and / or scrubbed off and / or reduced by repeated shampooing, rinsing and washing with cleaning compositions applied during showering and / or bathing, including, but not limited to, soaps, body washes, bubble bath salts, skin smoothers, etc. that typically and normally do not contain anionic and / or cationic surfactants. For these reasons, the shampooing and conditioning regimen provides the desired conditioning results for the hair. EXAMPLES

[0142] Working Example The following examples illustrate the present invention. The exemplary compositions can be prepared by conventional formulation and mixing techniques. It will be understood that other modifications of the present invention can be made within the skill of those skilled in the art of hair care formulation without departing from the spirit and scope of the present invention. All parts, percentages and ratios herein are by weight unless otherwise indicated. Some ingredients may come from suppliers as dilute solutions.

[0143] Surprisingly powerful hair conditioning enhancement was found with the combination of a dicarboxylic acid and an aliphatic monocarboxylic acid. The powerful synergistic effect of hair conditioning enhancement with the dicarboxylic acid / fatty monocarboxylic acid combination was seen in both rinse-off and leave-on product applications. The following samples were evaluated for conditioning performance: TIFF2025510474000002.tif84170● Fatty acid ester. Other similar esters include isopropyl palmitate and glyceryl monooleate. TIFF2025510474000003.tif95170

[0144] Test method: Combing force measurement Hair combability is therefore a key parameter to describe, on the one hand, the quality / degree of damage of the hair and / or, on the other hand, the conditioning effectiveness of a hair repair treatment.

[0145] The principle of most methods for determining combing properties consists in measuring the force of pulling a comb through a strand of hair under certain conditions (Ref.: CR Robbins, Chemical and Physical Behavior of Human Hair, 5th Edition, p. 646 ff., Springer-Verlag, Berlin Heidelberg 2012. ISBN 978-3-642-25610-3).

[0146] For this test, an automated device is used in which the hair tress to be tested is removed from a storage chamber and fixed to a force meter. The hair tress is automatically combed at a constant speed. For each combing stroke, the combing force is recorded as a function of the combed distance (length of the hair tress). For comparison, 20 combing strokes per tress on at least three hair tresses per product sample are averaged.

[0147] Combing force is the average force along the hair strand: the lower the combing force, the better the ease / smoothness of combing.

[0148] Preparation of hair tresses for combing force measurements To simulate hair damage, a 2 g, 17 cm long, medium blonde colored hair tress (Caucasian hair) is bleached twice and then soaked in tap water for 10 minutes (35° C.±2° C.) The tress is then conditioned to a relative humidity of 50% by weight and then combed twice (coarse and fine sides of a comb).

[0149] Applying the rinse-off conditioner / mask: 0.25 ml / g of the hair care composition to be tested is applied to the hair tress and massaged for 1 minute. Rinse the hair tress with tap water (6 L / min, 35°C ± 2°C) for 1 minute. The hair tress is then conditioned to a relative humidity of 50% by weight. The hair tresses were combed twice (with the coarse and fine sides of the comb), hung overnight in a climatic chamber (20°C, 65% relative humidity), then combed twice again and combing measurements were taken.

[0150] Leave-on conditioner application: 0.1 ml / g hair of the leave-on treatment is applied to the hair tress and massaged for 1 minute. The tress is then conditioned to a relative humidity of 50% by weight. The tress is combed twice (with the coarse and fine sides of the comb) and hung overnight in a climatic chamber (20°C, 65% relative humidity), then combed twice again and combing measurements are taken.

[0151] Test results Tables 3 and 4 show the wet combing force in Newtons (N) measured on hair materials that were damaged and then treated with the hair treatment compositions according to Tables 1 and 2. The treated hair materials that were subjected to the above mechanical combing measurements included damaged hair (bleached twice) that was not subjected to a conditioning treatment as a reference, and damaged hair (bleached twice) that was treated with test samples 1 to 10. TIFF2025510474000004.tif121170Superscript indices indicate statistically significant differences (t-test, p ≥ 0.95). TIFF2025510474000005.tif115170Superscript indices indicate statistically significant differences (t-test, p ≥ 0.95).

[0152] The results clearly show that hair treated with rinse-off conditioner / mask or leave-on treatment compositions containing both fatty monocarboxylic acid (oleic acid) and dicarboxylic acid (malic acid) (samples 4 and 5) shows better combing (lower combing force) versus hair treated with rinse-off conditioner / mask or leave-on treatment containing only dicarboxylic acid and no fatty monocarboxylic acid (sample 3) or with rinse-off conditioner / mask or leave-on treatment containing only fatty monocarboxylic acid and no dicarboxylic acid (sample 2).

[0153] In fact, fatty mono- or di-carboxylic acids alone do not improve the conditioning performance of rinse-on conditioner masks or leave-on treatments, therefore the combination of fatty mono- and di-carboxylic acids shows a synergistic effect on combability and hair repair benefits.

[0154] Examples with optional second component components Additional examples were prepared to show combing force results for variations in the second component present in the first component hair treatment composition, including dicarboxylic acids, fatty carboxylic acids, plus hydrocarbons and fatty acid esters as the first component.

[0155] The following examples demonstrate the benefit of a conditioner alone containing at least a dicarboxylic acid and a fatty carboxylic acid, and the enhancement of this benefit by the addition of one or more lipophilic components of a second component.

[0156] The following Examples 11-12 are prepared by melting the fatty alcohol, hydrocarbon, and fatty acid ester, adding an organic solvent, a portion of the water, and non-ionic surfactants such as ceteres-25 and coco glucoside to form an emulsion, followed by adding the water soluble ingredients and the remaining water and stirring vigorously to form a homogenous mixture of the conditioner / mask embodiment of the hair treatment composition of the present invention.

[0157] Example 11 (Leave-on treatment with first component, hydrocarbon and fatty acid ester) TIFF2025510474000006.tif95170

[0158] Example 12 (Leave-on treatment containing no lipids, fatty acids, or dicarboxylic acids) TIFF2025510474000007.tif75170

[0159] Combing force measurement The procedure for combing force measurement follows the description provided above with respect to Examples 1-10.

[0160] Preparation of Hair Strands for Combing Force Measurements in Examples 11-12 To simulate hair damage, a 2 g, 17 cm long, medium blonde colored hair tress (Caucasian hair) is bleached twice and then soaked in tap water for 10 minutes (35°C ± 2°C). The tress is then conditioned to a relative humidity of 50% by weight and then combed twice (coarse and fine sides of the comb). 0.25 ml / g hair of the hair care composition to be tested is applied to the tress and massaged for 1 minute. The tress is rinsed for 1 minute with tap water (6 L / min, 35°C ± 2°C). The tress is then conditioned to a relative humidity of 50% by weight. The tress is combed twice (coarse and fine sides of the comb) and placed inside the wet magazine of the combing device's storage chamber for the measurement of the combing force when actually wet.

[0161] Test results The following table shows the wet combing force in Newtons (N) of hair materials that have been damaged and then treated with a hair treatment composition according to the invention, as well as of a treatment composition lacking one or more of the four components of the hair treatment composition of the invention. The treated hair materials subjected to the above mechanical combing measurements included: a) Virgin hair b) Damaged hair (bleached twice), c) Damaged hair (bleached twice) treated with the liquid composition of Example 11 containing the first and second components of the hair treatment composition: dicarboxylic acid, fatty acid, fatty acid ester, hydrocarbon). d) Damaged hair (bleached twice) treated with a liquid composition containing the ingredients of Example 11, except that the composition does not contain the lipids, fatty acids, and dicarboxylic acids of Example 11; this is Example 12. TIFF2025510474000008.tif47170

[0162] The results show that hair treated with a composition containing lipids, fatty acids and dicarboxylic acids (sample c, Example 11) exhibits better combing (lower combing force) compared to a composition containing a leave-on conditioner composition that does not contain any of the first or second component components. These combing results cannot be compared to the combing results of Examples 1-10 due to the use of different hair materials and composition ingredients.
