Description

[Technical field]

[0001] The present invention relates to a hair conditioning composition comprising a basic amino acid, a fatty acid, a high melting point fatty alcohol, and an aqueous carrier, all of which are present in the formulation as L β A lamellar gel network matrix having a phase is formed. [Background technology]

[0002] A variety of approaches have been developed for conditioning hair. A common method of providing conditioning benefits is through the use of conditioning agents such as cationic surfactants and polymers, high melting point fatty compounds, low melting point oils, silicone compounds, and mixtures thereof. Most of these conditioning agents are known to provide various conditioning benefits. For example, some cationic surfactants, when used with some high melting point fatty compounds and aqueous carriers, can provide L β The composition is believed to provide a lamellar gel network matrix having a phase that is suitable for providing various conditioning benefits such as slippery feel during application to wet hair, and softness and moisturizing feel on dry hair. Summary of the Invention [Problem to be solved by the invention]

[0003] However, some consumers would prefer a product that does not have cationic surfactant molecules. β There is a continuing need to find alternative surfactants, particularly green chemistry surfactants, that can still form a lamellar gel network matrix with phases to achieve desired consumer benefits.

[0004] None of the existing technologies offers all of the advantages and benefits of the present invention, including performance, cost, safety, sustainable sources, and environmental considerations. [Means for solving the problem]

[0005] The present invention relates to a hair conditioning composition comprising a basic amino acid, a fatty acid, a high melting point fatty alcohol, and an aqueous carrier, all of which are represented by the formula: β A lamellar gel network matrix having a phase is formed. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0006] While the specification concludes with claims which particularly point out and distinctly claim the invention, it is believed the present invention will be better understood from the following description.

[0007] As used herein, "comprising" means that other steps and other ingredients that do not affect the end result may be added. This term encompasses the terms "consisting of" and "consisting essentially of."

[0008] All percentages, parts and ratios are based on the total weight of the compositions of the present invention unless otherwise specified. All such weights as they pertain to listed ingredients are based on the active ingredient level and, therefore, do not include carriers or by-products that may be included in commercially available materials.

[0009] As used herein, "mixture" is meant to include the simple combination of materials as well as any compounds that may result from such a combination.

[0010] QS in this specification means up to 100%.

[0011] composition The hair conditioning composition of the present invention comprises: a) a basic amino acid; b) a fatty acid; c) a high melting point aliphatic alcohol; d) an aqueous carrier; a) to d) are L β A lamellar gel network matrix having a phase is formed.

[0012] The object of the present invention is to β The objective of the present invention is to provide a stable conditioner composition that contains a lamellar gel network matrix having a phase and has a thick but melting application feel, clean rinsing, and dry appearance and conditioning effect. The combination of fatty alcohols, fatty acids, and basic amino acids with an aqueous carrier allows the preparation of a lamellar sheet structure that allows for a good rheological profile, providing good phase stability and wet feel. The lamellar sheet structure is robust enough to provide compositional stability, but is also sensitive to dilution and shear during product use, which can break down and provide excellent wet feel. The lamellar structure and composition further achieve dry conditioning benefits such as hair manageability, frizz control, and volume.

[0013] A typical hair conditioner composition includes structurants, such as fatty alcohols, feel / rheology modifier polymers, conditioning oils and agents, preservatives, fragrances / colorants, and cationic surfactants. Because consumers are more interested in products that contain only natural and mild ingredients, each of these hair conditioner components is investigated for how the composition can be structured to contain natural and mild ingredients as perceived by consumers, while still providing the performance and benefits that consumers expect. One area that can be modified is the surfactant. Rather than using cationic surfactant molecules, the inventors have formulated a hair conditioner composition that includes fatty acids, high melting point fatty alcohols, and basic amino acids. By incorporating different basic amino acids and fatty acids in the formulation at certain pH and processing conditions, flexibility in molecular design and supply chain is possible with all natural and mild ingredients, while still meeting the criteria of performance, cost, safety, sustainable source, and environmental friendliness.

[0014] L Β Lamellar gel network matrix with phase The composition of the present invention comprises L β The matrix contains a lamellar gel network having a L phase. β The lamellar gel network matrix having a phase, sometimes referred to as a gel network or gel matrix, comprises a fatty acid, an aliphatic alcohol, a basic amino acid, and an aqueous carrier. β The lamellar gel network matrix having phases is suitable for providing various conditioning benefits such as a slippery feel during application to wet hair and a soft and moisturizing feel on dry hair.

[0015] The hair conditioner composition of the present invention β The lamellar gel network matrix having a phase includes a surfactant that includes a basic amino acid and a longer alkyl chain fatty acid that contains C10-C22 as the main chain length.

[0016] The composition may comprise about 0.01% to about 15% of basic amino acids by weight of the hair conditioner composition. In some embodiments, the amount of basic amino acids may be about 0.01% to about 15%, preferably about 0.03% to about 10%, more preferably about 0.1% to about 6% by weight of the hair conditioner composition. In some embodiments, the basic amino acids comprise two or more amine groups. Suitable basic amino acids may include, but are not limited to, arginine, lysine, histidine, polyamino acids, and combinations thereof. In some embodiments, additional amino acids may be added, including polyamino acids. Polyamino acids may be added up to a 1:1 ratio with other amino acids. The iso-static point for each amino acid, and for all amino acids when combined, may be at least about 7. In some embodiments, the composition may further comprise a diamine that is not a basic amino acid, such as hydroxyethyl urea.

[0017] The basic amino acids of the present invention are combined with fatty acids at specific pH and processing conditions to form L β The composition may comprise from about 0.01% to about 15% fatty acid by weight of the hair conditioner composition. In some embodiments, the amount of fatty acid may be from about 0.01% to about 15%, preferably from about 0.05% to about 10%, more preferably from about 0.080.1% to about 5% by weight of the hair conditioner composition. The fatty acid may comprise saturated fatty acid and / or unsaturated fatty acid. The ratio of saturated fatty acid to unsaturated fatty acid may be from about 8:1 to about 1:4, or from about 4:1 to about 1:2. In some embodiments, the fatty acid may comprise from about 0.3% to about 5% unsaturated fatty acid by weight of the hair conditioner composition. The fatty acid may have, as a major component, a C10-C22 alkyl chain, in some cases a C16-C22 alkyl chain, and in still other cases a C18-C22 alkyl chain. Saturated fatty acids may include, but are not limited to, stearic acid, palmitic acid, behenic acid, and combinations thereof. Unsaturated fatty acids may include, but are not limited to, rapeseed acid, oleic acid, linoleic acid, and combinations thereof.

[0018] In some embodiments, the use of fatty acids having C12 to C14 alkyl chains may improve the wet detangling properties of the hair conditioning composition while maintaining a clean feel.

[0019] In some embodiments, compositions containing fatty acid alkyl chains shorter than C12-C14, in combination with high levels of arginine, can provide improved wet and dry conditioning.

[0020] However, in some embodiments, compositions containing longer fatty acid chains such as C22 may provide a coated, dry conditioning feel without the greasy residue feel, especially on very damaged hair.

[0021] In some embodiments, the surfactant may further comprise a cationic surfactant in addition to the basic amino acid.Suitable cationic surfactants may include, for example, behentrimonium methosulfate (BTMS), behentrimonium chloride (BTMAC), stearamidopropyl dimethylamine (SAPDMA), behenamidopropyl dimethylamine (BAPDMA), brassysilvaline esylate, and combinations thereof.

[0022] The hair conditioner composition may comprise at least about 60%, and in some embodiments at least about 80%, by weight of the hair conditioner composition, of an aqueous carrier.

[0023] L β The lamellar gel network matrix having a phase includes a fatty acid, a high melting point aliphatic alcohol, a basic amino acid, and an aqueous carrier. Generally, the mixture of the basic amino acid and the fatty acid together with the aqueous carrier can have a pH of at least about 4.5. The ratio of the basic amino acid to the fatty acid can be about 1:40 to about 40:1, preferably about 1:15 to about 30:1, or more preferably about 1:10 to about 20:1.

[0024] In some embodiments, the ratio of the sum of basic amino acid (a) plus fatty acid (b) to the sum of basic amino acid (a), fatty acid (b), and fatty alcohol (c), ((a+b) / (a+b+c)) by weight, can be from about 0.1 to about 0.9, preferably from about 0.2 to about 0.5. In some embodiments, the conditioner composition can comprise from about 6% to about 20% basic amino acid+fatty acid+fatty alcohol, by weight of the composition. These ratios and weight percentages provide better detangling and also improve L β This can provide a more robust lamellar gel network matrix having a phase structure.

[0025] The compositions of the present invention may be substantially free of ceramides. The compositions of the present invention may be substantially free of cholesterol. The compositions of the present invention may also be substantially free of a gel network made solely of non-ionic surfactants.

[0026] High Melting Point Aliphatic Alcohol In order to achieve the effects of the present invention, the high melting point aliphatic alcohol can be included in the composition at a level of about 2% by weight or more, preferably about 4% by weight or more, more preferably about 5% by weight or more, even more preferably about 5.5% by weight to about 15% by weight, preferably about 10% by weight.

[0027] The high melting point fatty alcohol useful herein has a melting point of 25°C or more, preferably 40°C or more, more preferably 45°C or more, even more preferably 50°C or more, from the viewpoint of stability of the lamellar gel network matrix with Lβ. Preferably, such melting point is up to about 90°C, more preferably up to about 80°C, even more preferably up to about 70°C, even more preferably up to about 65°C, from the viewpoint of easier production and easier emulsification. In the present invention, the high melting point fatty alcohol can be used as a single alcohol or as a blend or mixture of at least two high melting point fatty alcohols. When used as such a blend or mixture, the above melting point means the melting point of the blend or mixture.

[0028] The high melting point fatty alcohols useful herein are selected from the group consisting of fatty alcohols, fatty alcohol derivatives, fatty acid derivatives, and mixtures thereof. It will be understood by those skilled in the art that the alcohols disclosed in this section of the specification may belong to more than one classification in some cases (e.g., some fatty alcohol derivatives may also be classified as fatty acid derivatives). However, the classification given is not intended to limit the specific alcohol, but is made so for the convenience of classification and nomenclature. Furthermore, those skilled in the art will understand that depending on the number and position of double bonds and the length and position of branching, a specific alcohol with certain essential carbon atoms may have a melting point below the melting point preferred in the present invention above. Such alcohols with low melting points are not intended to be included in this section. Non-limiting examples of high melting point alcohols can be found in the International Cosmetic Ingredient Dictionary, Fifth Edition, 1993, and the CTFA Cosmetic Ingredient Handbook, Second Edition, 1992.

[0029] The high melting point fatty alcohols useful herein are those having from about 14 to about 30 carbon atoms, preferably from about 16 to about 22 carbon atoms. These fatty alcohols are saturated and may be straight chain or branched chain alcohols.

These alcohols are known to have the above melting points. However, they often have lower melting points when supplied, because such supplied products are often mixtures of fatty alcohols with alkyl chain length distributions in which the predominant alkyl chains are cetyl, stearyl, or behenyl groups. In the present invention, more preferred fatty alcohols are cetyl alcohol, stearyl alcohol, and mixtures thereof.

[0031] Commercially available high melting point fatty alcohols useful herein include cetyl alcohol, stearyl alcohol, and behenyl alcohol under the trade name KONOL series available from Shin Nihon Rika (Osaka, Japan) and NAA series available from NOF (Tokyo, Japan); pure behenyl alcohol under the trade name 1-docosanol available from WAKO (Osaka, Japan).

[0056] Manufacturing method The present invention also relates to a method for making a hair conditioning composition, which is as follows. 1. A method for producing a hair conditioner composition, comprising: A basic amino acid; B fatty acids; c. a high melting point aliphatic alcohol; d. an aqueous carrier; The method comprises the steps of: a) adding water having a temperature higher than the melting point of the fatty acid, the fatty alcohol, and the mixture thereof (about 80°C to 90°C); b) fatty alcohols and Adding a basic amino acid to hot water (about 80°C to 90°C) before adding the fatty acid; c) preparing a homogenous premix by combining fatty acids and fatty alcohols at a temperature above either of their respective melting points and adding it to hot water (approximately 80° C. to 90° C.); and d) cooling the mixture below the phase transition temperature to form a gel network matrix.

[0057] Preparation method Water is prepared at about 80°C to about 90°C. A basic amino acid is added to the prepared hot water. Then, an aliphatic alcohol and a fatty acid are added to the prepared hot solution to prepare a dispersed homogeneous mixture at about 85°C. The mixture is then cooled to less than 40°C while stirring. β A lamellar gel network matrix having a phase is formed. If included, silicone compounds, fragrances, preservatives are added to the L phase with stirring after the composition has cooled to room temperature. β The phase is added to a lamellar gel network matrix.

[0059] An alternative method could be to prepare a homogenous premix by combining the fatty acid and fatty alcohol at a temperature above either of their individual melting points and add it to the hot water (about 80-90°C) in place of steps b) and c). Another alternative method could be to add the basic amino acid to the hot water (about 80-90°C) before adding the fatty alcohol and fatty acid.

[0060] A further alternative method of making the hair conditioner composition comprises the steps of: The method may include the steps of: a) creating a solid form material by combining a basic amino acid, an aliphatic alcohol, and a fatty acid; and b) then combining a) with an aqueous chassis.

[0061] The method further comprises adding additional ingredients such as silicone or oil compounds, fragrances, preservatives, and aesthetic substances, if any, to the L β The method may further include adding to a lamellar gel network matrix having a phase. The conditioning compositions of the present invention may be prepared by any conventional method known in the art.

[0063] The following examples further describe and demonstrate embodiments within the scope of the present invention. These examples are provided for illustrative purposes only and should not be construed as limiting the present invention, since many variations thereof are possible without departing from the spirit and scope of the present invention. Where applicable, components are identified by chemical or CTFA name, or are otherwise defined below.

[0064] Table 1 below shows five formulations of hair conditioner. Examples 1 and 2 are examples of the invention that include a basic amino acid, a fatty acid, a fatty alcohol, and an aqueous carrier, which together form L β Form a lamellar gel network matrix having a L phase. β The presence of a lamellar gel network matrix with phases is shown by X-ray (SAX / WAX) analysis data. Comparative Example 3 is the same as Example 1 and Example 2, except that Example 3 does not contain any basic amino acid.

[0065] Small angle X-ray scattering ("SAXS") is used to resolve periodic structures in mesophases and is essentially an X-ray diffraction technique. It is used in conjunction with conventional wide angle X-ray diffraction ("WXRD") to characterize aggregated structures such as micelles, gel networks, lamellae, hexagonal liquid crystals, and cubic liquid crystals. Different mesophases that exhibit periodic structures can be characterized by the relative positions of reflections (d-spacings) derived from the Bragg equation (d=λ / 2Sinθ), where d represents the interplanar spacing, λ represents the radiation wavelength, and θ represents the scattering (diffraction) angle.

[0066] The one-dimensional lamellar gel network phase is characterized by d-spacing ratios d1 / d1, d1 / d2, d1 / d3, d1 / d4, d1 / d5 with values ​​such as 1:2:3:4:5 in the SAXS region (long-range order) and one or two invariant reflections in the WXRD region (short-range) centered at about 3.5 and 4.5 Å over a broad halo background. Other mesophases (e.g., hexagonal or cubic) will have characteristically different d-spacing ratios.

[0067] Both WXRD and SAXS data were generated as described in more detail in the Test Methods below. As seen in Table 1, inventive Examples 1 and 2 also exhibit SAXS d-spacings and WXRD reflections in the range of 3.5-4.5, indicating a lamellar gel network matrix. Example 3, in contrast, exhibits phase separation and L β It shows that a lamellar gel network matrix with a phase cannot be formed without arginine. Comparative Example 4 does not contain any basic amino acids, but uses a conventional cationic surfactant instead. Qualitative analysis of the SAX peak intensity data shows that Examples 1 and 2 of the present invention have significantly higher L than Example 4, which uses a conventional cationic surfactant. β Example 5 also includes a basic amino acid, arginine, and a conventional cationic surfactant, demonstrating that a lamellar gel network matrix having a phase can be more effectively formed.

[0068] Inventive Example 1 and Comparative Example 4 were tested for experience during use as rinse-off conditioners. The clean / squeakiness on wet hair after rinsing was measured by a Sensory Descriptive Analysis Panel (DAP) test using tresses of treated hair samples evaluated by 8 highly trained expert panelists. Inventive Example 1 produced more squeakiness after rinsing compared to Example 4, a formula with a conventional cationic surfactant. Another set of tresses was pretreated with Example 1 and Example 4, dried overnight, and evaluated by 8 highly trained expert panelists for visual hair evenness and dry smooth appearance. Again, Example 1 showed higher scores for hair evenness and dry smooth appearance than Example 4.

[0069] Inventive Example 1 and Comparative Example 5 were tested for experience during use as a leave-on hair conditioner. Example 1 provided less of a heavy coating or residue feel during application and also more frizz control compared to Example 5. All test methods are disclosed in more detail below.

[0070] [Table 1] * It has a chain distribution of approximately 50 / 50 C16 / C18. S=significant difference

[0071] Tables 2 and 3 below contain further inventive examples. All inventive examples contain L β The resulting lamellar gel network matrix having a crystalline phase is then fully formed.

[0072] [Table 2] * It has a chain distribution of approximately 50 / 50 C16 / C18.

[0073] [Table 3] * Plantasil Micro (Dicaprylyl Ether (and) Decyl Glucoside (and) Glyceryl Oleate) from BASF ** It has a chain distribution of approximately 50 / 50 C16 / C18.

[0074] Although conditioners of the present invention can use fatty acids having any of the C10-C22 alkyl chain lengths, conditioners of the present invention using fatty acids having C12-C14 alkyl chains can improve the wet detangling properties of hair conditioning compositions while maintaining a clean feel, compared to conditioners of the present invention containing C16-C22 alkyl chains. Table 4 shows five additional inventive examples. Examples 9, 20, 21, 6, and 10 have C12, C14, C16, C18, and C22 alkyl chains, respectively. Each was made and tested with a sensory panel for ability to remove tangles during application, wet slip during application, and smooth feel when dry. As can be seen in Table 4, the shorter alkyl chain fatty acids (C12 and C14) of inventive Examples 9 and 20 performed best with the sensory panel. Panelists rated these attributes of inventive Examples 9 and 20 significantly higher than the same attributes for the control of Example 6, which has a fatty acid alkyl chain of C18. Panelists rated these attributes for Example 21 and Example 10 in the same manner as the Example 6 control.

[0075] [Table 4] * The control is C18 stearic acid from Example 6. ** It has a chain distribution of approximately 50 / 50 C16 / C18. A = Clearly significantly lower strength for the attribute B = significantly lower intensity for the attribute C = equal strength for attributes D = significantly higher intensity for the attribute E = Significantly higher intensity evident for the attribute

[0076] In some embodiments, the ratio of basic amino acids to fatty acids, weight percent to weight percent, can be from about 20:1 to about 1:1, in some embodiments from about 20:1 to about 10:1. Table 5 below shows examples of the present invention having various ratios of basic amino acids to fatty acids (arginine to lauric acid). Examples 16 and 22, with basic amino acids to fatty acids ratios of 20:1 and 10:1, respectively, performed best with a sensory panel evaluating the compositions for the following attributes: detangle during application, smooth feel upon drying, ease of distribution onto wet hair underneath, and ease of distribution onto dry hair underneath. Other examples evaluated had basic amino acids to fatty acids ratios of 40:1, 4:1, 2:1, and 1:1, all compared to the control (Example 9) which had a ratio of 1:10.

[0077] [Table 5] * The control is C12 lauric acid from Example 9. A = Clearly significantly lower strength for the attribute B = significantly lower intensity for the attribute C = equal strength for attributes D = significantly higher intensity for the attribute E = Significantly higher intensity evident for the attribute

[0078] In some embodiments, the (a+b) / (a+b+c) ratio (weight ratio of the sum of basic amino acids and fatty acids to the sum of basic amino acids, fatty acids, and fatty alcohols) can be significant. A range of about 0.1 to about 0.9 provides better detangling and L β It can provide a more robust lamellar gel network matrix with a phase structure. The range of 0.2 to 0.5 is even more effective. Table 6 shows the ratios of Examples 16, 27, and 28. In Example 16, the ratio is 0.33, and the composition shows improved performance in detangling during application and smooth feel when dry, compared to Examples 27 and 28, which have ratios of 0.14 and 0.91, respectively.

[0079] [Table 6] * The control is C12 lauric acid from Example 9.

[0080] In some embodiments, compositions containing shorter fatty acid alkyl chains of C12-C14 can provide improved wet and dry conditioning in combination with high levels of arginine. In Table 7, Examples 16, 29, 30, and 31 of the present invention all have an arginine to fatty acid ratio of 20:1. When Examples 16, 29, 30, and 31 are compared to a control having an arginine to fatty acid ratio of 1:10, Examples 16 and 29, which have shorter chain fatty acids of C12 and C14, respectively, performed better than Examples 30 and 31, which have fatty acid chain lengths of C18 and C22, respectively. Examples 16 and 29 had a smooth feel when dry, detangled during application, and significantly higher strength for lining and smoothing.

[0081] [Table 7] * The control is C12 lauric acid from Example 9. ** It has a chain distribution of approximately 50 / 50 C16 / C18.

[0082] In some embodiments, compositions containing longer fatty acid chains such as C22 may provide a coated dry conditioning feel without a greasy residue feel, especially on very damaged hair. In Table 8, Example 37, the composition containing a fatty acid with C22 performs better than Example 6, the composition containing a fatty acid with C18, to provide a dry coating conditioning feel according to the sensory panel.

[0083] [Table 8] ** It has a chain distribution of approximately 50 / 50 C16 / C18. A = Clearly significantly lower strength for the attribute B = significantly lower intensity for the attribute C = equal strength for attributes D = significantly higher intensity for the attribute E = Significantly higher intensity evident for the attribute

[0084] Test Method 1. Wet Specialized Sensory Method This is an expert sensory panel test method, which uses a highly expert sensory panel of three members to evaluate specific attributes during the wet stage of hair treatment. The treatment protocol for hair treatment is as follows: a. Rinse 20g of Hair Switch with water and squeeze the water out from the top to the bottom once. b. 1 ml of conditioner was applied to the front and 1 ml of conditioner was applied to the back. c. Lather product onto the hair switch for 30 seconds, 30 strokes. d. Next, rinse the hair for 15 seconds on the front and 15 seconds on the back. Squeeze the water out once from the top to the bottom.

[0085] The sensory attributes evaluated during the wetting stage are listed below. · Wet Slippage During Application: Panelists rate finger speed from top to bottom on wet hair while applying 30 strokes of the Hair Switch. Detangling During Application: Panelists evaluate detangling performance with a finger from top to bottom on wet hair after three product applications. Post-rinse squeaky feeling: Panelists rate the clean feeling of wet hair after rinsing.

[0086] The attribute score ratings are compared to a control sample defined in each of the tests. Each classification score is considered a significant difference from the other, indicating consistency in the attributes rated by all three sensitive panelists. Mixed score data between panelists will result in the lower score being placed. A = Clearly significantly lower strength for the attribute B = significantly lower intensity for the attribute C = equal strength for attributes D = significantly higher intensity for the attribute E = Significantly higher intensity evident for the attribute Fast Rinse / Clean Feeling Descriptive Test: When asked whether the Hair Switch rinses quickly and feels clean, panelists are asked to select "yes" or "no." · Ease of Distribution onto Wet Hair, Bottom: Panelists evaluate the ease with which the product spreads onto wet hair from root to tip during product application.

[0087] 2. Drying Special Sensory Method This is an expert sensory panel test method, in which a highly expert sensory panel of three members is used to evaluate specific attributes during the drying stage of hair treatment. The treatment protocol for hair treatment is as follows: a. Rinse 20g of Hair Switch with water and squeeze the water out from the top to the bottom once. b. 1 ml of conditioner was applied to the front and 1 ml of conditioner was applied to the back. c. Apply 30 generous strokes of product onto the Hair Switch for 30 seconds. d. Next, rinse the hair for 15 seconds on the front and 15 seconds on the back. Squeeze the water out once from the top to the bottom. e. Let dry overnight

[0088] The sensory attributes evaluated during the drying stage are listed below. Dry and smooth feel: Panelists evaluate the smooth surface feel of the hair. Evenness and Smoothness: Panelists evaluate the visual evenness and smooth appearance of hair when dry. Dry Coating Conditioning Feel: Panelists evaluate the coating feel on hair · Ease of Distribution on Bottom Dry Hair: Panelists evaluate the ease of spreading the product from root to tip on dry hair using 30 generous applications.

[0089] The score ratings of the attributes are compared to the control listed in each table. Each classification score is considered a significant difference from the other and indicates consistency in the attributes rated by all three sensitive panelists. Mixed score data between panelists will result in the lower score being placed. A = Clearly significantly lower strength for the attribute B = significantly lower intensity for the attribute C = equal strength for attributes D = significantly higher intensity for the attribute E = Significantly higher intensity evident for the attribute

[0090] 3. General conditioning sensory method This is an expert sensory panel test method, in which a highly expert sensory panel of three members is used to evaluate specific attributes during the drying stage of hair treatment. The treatment protocol for hair treatment is as follows: a. Rinse 20g of Hair Switch with water and squeeze the water out from the top to the bottom once. b. Apply 1ml of conditioner to the front and 1ml of conditioner to the back. c. Apply 30 generous strokes of product onto the Hair Switch for 30 seconds. d. Rinse the front for 15 seconds and the back for 15 seconds, squeezing the water out from top to bottom once. e. Let dry overnight

[0091] The sensory attributes evaluated during this method are listed as "Conditioning" in the Example Tables. Panelists were asked to evaluate the wet stage for wet spread and slip, evaluate the dry smoothness during the dry stage, and rate the conditioning feel as either "acceptable" or "unacceptable."

[0092] 4.DSC analysis method Differential scanning calorimetry (DSC) is a useful tool since it gives the phase transition (melting or freezing) temperatures of the structures formed, as well as the thermal energies of melting and freezing. 1. Equilibrate at 0.00℃ 2. 5.00°C / min to 90.00°C ramp 3. Isothermal 5.0 minutes 4. 5.00°C / min to 0.00°C ramp 5. Isothermal 5.0 minutes

[0093] Descriptive test for DSC peaks >30°C: The DSC graph at a slope of 5.00°C / min to 90.00°C gives the melting phase transition temperature of the structure formed. If a peak is observed above 30°C, it is noted as "Yes".

[0094] 5. Visual assessment of product stability Stability is a visual assessment to ensure that the product is consistently stable over a specific period of time. The product composition was placed in three different conditions: -5°C, 25°C, and 40°C. Evaluations are performed at different intervals. 1) Stable during manufacturing 2) Stable after 1 week

[0095] Descriptive Test of Product Stability: If the visual evaluation of the product is stable at different intervals, it is stated as stable. If the visual evaluation of the product shows phase separation at any of the intervals, it is stated as phase separated.

[0096] 6. SAX / WAXS Analysis Small angle X-ray scattering ("SAXS"), used to resolve periodic structures in mesophases, is essentially an X-ray diffraction technique. It is used in conjunction with conventional wide angle X-ray diffraction ("WXRD") to characterize aggregated structures such as micelles, gel networks, lamellae, hexagonal liquid crystals, and cubic liquid crystals. Different mesophases that exhibit periodic structures can be characterized by the relative positions of reflections (d-spacings) derived from the Bragg equation (d=λ / 2Sinθ), where d represents the interplanar spacing, λ represents the radiation wavelength, and θ represents the scattering (diffraction) angle.

[0097] The one-dimensional lamellar gel network phase is characterized by d-spacing ratios d1 / d1, d1 / d2, d1 / d3, d1 / d4, d1 / d5 with values ​​such as 1:2:3:4:5 in the SAXS region (long-range order) and one or two invariant reflections in the WXRD region (short-range) centered at about 3.5 and 4.5 Å over a broad halo background. Other mesophases (e.g., hexagonal or cubic) will have characteristically different d-spacing ratios.

[0098] Both WXRD and SAXS data are collected simultaneously on a Xenocs Xeuss2.0 equipped with a Dectris Pilatus100K detector (WXRD) and a Dectris Pilatus 3R 200K-A detector (SAXS) at sample-to-detector distances of 163.13 mm (WXRD) and 2492.37 mm (SAXS) for 90 min with high-resolution collimation. The setup has a vacuum chamber. Sample pieces are injected into quartz glass capillary tubes (diameter = 2.0 mm, length = 80 mm, wall thickness = 0.01 mm), mounted in a grooved capillary sample holder and placed in the path of the X-ray beam. Data are collected and analyzed using Xenocs Foxtrot software. The 2D data are integrated azimuthally and reduced by the SAXS utility software to intensity relative to the scattering vector (q) or its d-equivalent.

[0099] 7. Rheological Methods Rheology is used to evaluate and characterize product samples. Two important rheological methods have been identified and are described below. -950s through flow curve -1 Shear stress at: This is a shear rate of 0.1 to 1000 s in 1 min using a cone-plate geometry. -1 The shear rate was logarithmically ramped to 950 s -1 This is a method to read the shear stress value σ (Pa). · Oscillatory Measurement G' / G'': This is an oscillatory stress method with a ramp from 0.1 to 100 Pa to measure the storage modulus G' and the loss modulus G'', where G'' gives the viscoelastic information of the sample in its "rest" state, and the yield stress value σ (Pa), which is the stress required to permanently deform (start to flow).

[0100] The acceptable rheological range of shear stress is 5 Pa to 1500 Pa. For oscillatory measurements, the storage modulus G' ranges from 30 Pa to 45000 Pa, and the loss modulus G'' ranges from 10 Pa to 20000 Pa.

[0101] Wet and dry DAP functionality versus rinse-off Squeakiness after rinsing (wet DAP ROC) The clean feeling of wet hair after rinsing is evaluated by the squeaky feeling measured by the Sensory DAP Descriptive Analysis Panel Test using tresses of treated hair samples evaluated by 8 highly trained expert panelists. 0.4 ml of the composition is applied to a 4 g hair sample. After the composition is spread on the hair sample, it is rinsed with water for about 15 seconds. The water is squeezed out of the hair sample, and the hair sample is then rated for feel on a scale of 1 to 100, the higher the number, the more squeaky after rinsing. A difference of 5 points or more is considered a significant difference.

[0102] Uniformity & Smoothness (Dry DAP ROC) Another set of hair tresses is pretreated with the composition, allowed to dry overnight, and then visually evaluated for hair evenness and smooth dry appearance by eight highly trained expert panelists. The scale is 1 to 100, with higher numbers representing better evenness and smoothness. A difference of 5 points or more is considered significant.

[0103] Heavy coating / residue (wet DAP functionality vs. leave-on) The clean feel during application as a leave-on treatment is evaluated by a heavy coating / residue rating measured by a Sensory DAP Descriptive Analysis Panel Test using swatches of treated hair samples as assessed by eight highly trained expert panelists. 0.4 ml of the composition is applied to a 4 g hair sample. After spreading the composition on the hair sample, the heavy coating / residue is rated on a scale of 1 to 100, with higher numbers representing a heavier coating or residue feel. A difference of 5 points or more is considered a significant difference.

[0104] OSM(Optical Sectioning Method) Shrinkage Measurement for Leave-On A set of hair tresses is treated with hair care products and then exposed to high humidity conditions.The hair tresses are then hung vertically and their shapes are measured by a laser scanning system.The volume of the hair tresses and fibers in the outer surface associated with frizzy hair is calculated, with lower values ​​indicating less volume and less frizz.The values ​​corresponding to the volume and frizz of the set of hair tresses corresponding to different hair treatments are tested for statistical significance at a 95% confidence interval.
