Description

[Technical Field]

[0001] The present disclosure relates to a mild shampoo composition comprising an alkyl polyglucoside, sclerotium gum, and a cationic polymer, which provides consumer-desired wet conditioning and a moderate viscosity for ease of use. [Background technology]

[0002] Human hair becomes dirty due to contact with the surrounding environment and sebum secreted by the scalp. Dirty hair has a dirty feel and an unattractive appearance. Applying a shampoo composition to dirty hair and washing it can restore a clean and attractive appearance by removing oil and other dirt from the hair. Known shampoo compositions typically use anionic surfactants to remove oil and dirt from hair. However, shampoos containing anionic surfactants can result in many undesirable properties, such as poor hair feel. Cationic polymers are commonly used in anionic surfactant cleansing compositions to provide moisture to hair and to detangle hair when wet. Nonionic surfactants are known to be gentle on the skin, but are also known to be difficult to use in combination with charged polymers (cationic polymers), which can destabilize the composition. Furthermore, nonionic surfactant systems are typically thin (low viscosity) and may require thickening polymers to increase viscosity to prevent the solution from dripping from the consumer's hands before application to the hair. However, the combination of cationic polymers with commonly used thickeners, such as guar gum, typically destabilizes the composition. Surprisingly, it has been discovered that sclerotium gum, with its unique triple helix structure, can stabilize cationic polymers to achieve a single-phase stable cleansing composition that provides a range of desired wet conditioning benefits and desired viscosities. Summary of the Invention [Problem to be solved by the invention]

[0003] It would be desirable to have a shampoo composition that cleans without the use of anionic surfactants and provides good in-use physical properties while achieving desired hair benefits. Surprisingly, it has been discovered that a shampoo composition comprising a nonionic surfactant alkyl polyglucoside, sclerotium gum, and a cationic polymer is phase stable and provides the wet conditioning and moderate viscosity desired by consumers for ease of use.

[0015] Shampoo composition The shampoo compositions described herein provide consumers with the hair conditioning feel they desire, and the shampoo compositions are stable and have a viscosity that provides a good in-use experience. The shampoo compositions include a nonionic surfactant, such as an alkyl polyglucoside. The shampoo compositions further include sclerotium gum and a cationic polymer. The compositions remain phase stable, have good viscosity, and continue to provide the desired cleansing lather, fast rinsing, and a clean hair feel.

[0016] The shampoo composition is substantially free of ionic surfactants, including sodium alkyl sulfate, sodium cocoyl isethionate, sodium lauroyl sarcosinate, cocamidopropyl betaine, sodium lauroamphoacetate, cetyltrimethylammonium chloride, behenyltrimethylammonium chloride, and mixtures thereof. As used herein, substantially free of ionic surfactants means less than 1%, 0% to 1%, 0% to 0.5%, 0.1% to 0.2%, or 0% to 0.3% by weight of ionic surfactants.

[0017] Nonionic surfactants The shampoo composition includes 5% to 35% of a nonionic surfactant alkyl polyglucoside. The shampoo composition includes 5% to 35% by weight of alkyl polyglucoside, 5% to 25% by weight of alkyl polyglucoside, 7% to 20% by weight of alkyl polyglucoside, and any combination thereof. The nonionic surfactant can be a polyglucoside selected from decyl glucoside, caprylyl glucoside, caprylyl / capryl glucoside, undecyl glucoside, octyl glucoside, and mixtures thereof.

[0018] Nonionic surfactants have the following structure:

[0019] [ka] where "R" is an alkyl or alkenyl group having 8 to 20 carbons and "m" is a degree of polymerization from 1 to 5. Alternatively, R is 8 to 16 carbons, or alternatively, R is 8 to 12 carbons.

[0020] Nonionic surfactants have the following structure:

[0021] [ka] wherein R is a C10 alkyl or alkenyl group and the degree of polymerization (m) is 1.

Sclerotium gum, also known as scleroglucan, is a branched polysaccharide. In some instances, the primary structure of scleroglucan consists of glucose molecules linked by β-(1,3) bonds, with every third glucose molecule in the primary structure containing an additional glucose molecule linked by a β-(1,6) bond. In certain solutions, scleroglucan forms a triple helix shape.

[0023] Figure 1 shows an example of a typical sclerotium gum structure. Figure 2 shows an example of a β-(1,3)-β-(1,6) glucan structure, demonstrating the (3:1) side-chain branching ratio of scleroglucan (Martin et al., 2007). Figure 3 shows an example of the three-dimensional conformation of a scleroglucan triplex (Crescenzi et al., 1988). Specific examples of sclerotium gum include Amigum ER, available from Alban Muller, and Actigum CS 11 QD, available from Cargill.

[0024] cationic polymer The shampoo composition may contain a cationic polymer for wet conditioning benefits. Suitable cationic polymers may include (a) cationic guar polymers, (b) cationic non-guar galactomannan polymers, (c) cationic starch polymers, (d) cationic copolymers of acrylamide monomers and cationic monomers, (e) synthetic non-crosslinked cationic polymers that may or may not form lyotropic liquid crystals when combined with a detersive surfactant, and (f) cationic cellulose polymers. In certain examples, two or more cationic polymers may be included.

[0025] The cationic polymer may comprise 0.05% to 3%, 0.075% to 2.0%, or 0.1% to 1.0% by weight of the shampoo composition. The cationic polymer may have a cationic charge density of 0.9 meq / g or more, 1.2 meq / g or more, and 1.5 meq / g or more. However, the cationic charge density may also be about 7 meq / g or less, or even 5 meq / g or less. The charge density may be measured at the pH of the shampoo composition's intended use (e.g., pH 3 to 9, or pH 4 to 8). The average molecular weight of the cationic polymer may generally be 10,000 to 10,000,000, 50,000 to 5,000,000, 100,000 to 3,000,000, and 100,000 to 2,500,000. Lower molecular weight cationic polymers may also be used. A lower molecular weight cationic polymer can provide greater translucency within the liquid carrier of the shampoo composition. The cationic polymer can be a single type, such as the cationic guar polymer guar hydroxypropyltrimonium chloride, having a weight average molecular weight of 2,500,000 g / mol or less, and the shampoo composition can be substantially free of additional cationic polymers. As used herein, substantially free of additional cationic polymers means 0 to 0.05% additional cationic polymers.

[0026] Cationic Guar Polymer The cationic polymer may be a cationic guar polymer, which is a cationically substituted galactomannan (guar) gum derivative. Suitable guar gum for the guar gum derivative can be obtained as a naturally occurring material from the seeds of the guar plant. As can be understood, the guar molecule is a linear mannan in which single-membered galactose units branch at regular intervals on alternating mannose units. The mannose units are linked to each other by β(1-4) glycosidic bonds. The galactose branches are formed by α(1-6) bonds. The cationic derivative of guar gum can be obtained through the reaction between the hydroxyl groups of the polygalactomannan and a reactive quaternary ammonium compound. The degree of substitution of cationic groups on the guar structure can be sufficient to provide the required cationic charge density described above.

[0027] The cationic guar polymer may have a weight average molecular weight ("M.Wt.") of less than 2,500,000 g / mole and a charge density of 0.05 meq / g to 2.5 meq / g. Alternatively, the cationic guar polymer may have a weight average molecular weight of less than 1,500,000 g / mole, 150,000 g / mole to 1,500,000 g / mole, 200,000 g / mole to 1,500,000 g / mole, 300,000 g / mole to 1,500,000 g / mole, and 700,000,000 g / mole to 1,500,000 g / mole. The cationic guar polymers may have a charge density of 0.2 meq / g to 2.2 meq / g, 0.3 meq / g to 2.0 meq / g, 0.4 meq / g to 1.8 meq / g, and 0.5 meq / g to 1.7 meq / g.

[0028] The cationic guar polymer may have a weight average molecular weight of less than 1,000,000 g / mol and a charge density of 0.1 meq / g to 2.5 meq / g. The cationic guar polymer may have a weight average molecular weight of less than 900,000 g / mol, 150,000 to 800,000 g / mol, 200,000 to 700,000 g / mol, 300,000 to 700,000 g / mol, 400,000 to 600,000 g / mol, 150,000 to 800,000 g / mol, 200,000 to 700,000 g / mol, 300,000 to 700,000 g / mol, and 400,000 to 600,000 g / mol. The cationic guar polymers have charge densities of 0.2 meq / g to 2.2 meq / g, 0.3 meq / g to 2.0 meq / g, 0.4 meq / g to 1.8 meq / g, and 0.5 meq / g to 1.5 meq / g.

[0029] The shampoo composition may comprise from 0.01% to less than 0.7%, from 0.04% to 0.55%, from 0.08% to 0.5%, from 0.16% to 0.5%, from 0.2% to 0.5%, from 0.3% to 0.5%, and from 0.4% to 0.5%, by weight of the shampoo composition, of cationic guar polymer.

[0030] Cationic guar polymers can be formed from quaternary ammonium compounds conforming to general formula II:

[0031] [ka] In the formula, R 3 , R 4 , and R 5 is a methyl or ethyl group, and R 6 is an epoxyalkyl group of general formula III:

[0032] [ka] Or R 6 is a halohydrin group of general formula IV:

[0033] [ka] wherein R 7 is a C1-C3 alkylene, X is chlorine or bromine, and Z is an anion such as Cl-, Br-, I-, or HSO4-.

[0034] Suitable cationic guar polymers may conform to the general formula V:

[0035] [ka] In the formula, R 8 is guar gum, R 4 , R 5 , R 6 , and R 7 is as defined above, and Z is a halogen.

[0036] Suitable cationic guar polymers can conform to Formula VI:

[0037] [ka] In the formula, R 8 is guar gum.

[0038] Suitable cationic guar polymers may also include cationic guar gum derivatives such as guar hydroxypropyltrimonium chloride. Suitable examples of guar hydroxypropyltrimonium chloride include the Jaguar series available from Solvay SA, the Hi-Care series available from Rhodia, and N-Hance and AquaCat available from Ashland Inc. Jaguar® C-500 has a charge density of 0.8 meq / g and a molecular weight of 500,000 g / mol, Jaguar® C-17 has a cationic charge density of 0.6 meq / g and a molecular weight of 2,200,000 g / mol, Jaguar® C13S has a molecular weight of 2,200,000 g / mol and a cationic charge density of 0.8 meq / g, Hi-Care 1000 has a charge density of 0.7 meq / g and a molecular weight of 600,000 g / mol, N-Hance 3269 and N-Hance 3270 have a charge density of 0.7 meq / g and a molecular weight of 425,000 g / mol, N-Hance 3196 has a charge density of 0.8 meq / g and a molecular weight of 1,100,000 g / mol, and AquaCat CG518 has a charge density of 0.9 meq / g and a molecular weight of 50,000 g / mol. N-Hance BF-13 and N-Hance BF-17 are borate-free guar polymers.

[0039] Cationic Non-Guar Galactomannan Polymers The cationic polymer may be a galactomannan polymer derivative. Suitable galactomannan polymers may have a mannose-to-galactose ratio of greater than 2:1 on a monomer-to-monomer basis and may be a cationic galactomannan polymer derivative or an amphoteric galactomannan polymer derivative having a net positive charge. As used herein, the term "cationic galactomannan" refers to a galactomannan polymer to which cationic groups have been added. The term "amphoteric galactomannan" refers to a galactomannan polymer to which cationic and anionic groups have been added such that the polymer has a net positive charge.

[0040] Galactomannan polymers can be present in the endosperm of legume seeds. Galactomannan polymers are composed of a combination of mannose and galactose monomers. Galactomannan molecules are linear mannans in which single-membered galactose units branch at regular intervals on specific mannose units. The mannose units are linked to each other by β(1-4) glycosidic bonds. Galactose branches occur via α(1-6) linkages. The ratio of mannose to galactose monomers varies depending on the plant species and may also be affected by climate. Non-guar galactomannan polymer derivatives may have a mannose-to-galactose ratio greater than 2:1 on a monomer-to-monomer basis. Suitable mannose-to-galactose ratios may also be greater than 3:1 or greater than 4:1. Analysis of the mannose-to-galactose ratio is well known in the art and is typically based on measuring galactose content.

[0041] The gums used to prepare the non-guar galactomannan polymer derivatives can be obtained from naturally occurring materials such as plant seeds or beans. Examples of various non-guar galactomannan polymers include tara gum (3 parts mannose / 1 part galactose), carob or lob (4 parts mannose / 1 part galactose), and cassia gum (5 parts mannose / 1 part galactose).

[0042] The non-guar galactomannan polymer derivatives can have a molecular weight of from 1,000 g / mol to 10,000,000 g / mol and a molecular weight of from 5,000 g / mol to 3,000,000 g / mol.

[0043] The shampoo compositions described herein may include a galactomannan polymer derivative having a cationic charge density of 0.5 meq / g to 7 meq / g. The galactomannan polymer derivative may have a cationic charge density of 1 meq / g to 5 meq / g. The degree of substitution of cationic groups onto the galactomannan structure may be sufficient to provide the required cationic charge density.

[0044] The galactomannan polymer derivative may be a cationic derivative of a non-guar galactomannan polymer, obtained by reacting the hydroxyl groups of the polygalactomannan polymer with a reactive quaternary ammonium compound. Suitable quaternary ammonium compounds for use in forming the cationic galactomannan polymer derivative include those conforming to the general formulas II-VI defined above.

[0045] The cationic non-guar galactomannan polymer derivatives formed from the above reagents can be represented by the general formula VII:

[0046] [ka] wherein R is a gum. The cationic galactomannan derivative can be gum hydroxypropyltrimethylammonium chloride, which can be more specifically represented by general formula VIII:

[0047] [ka]

[0048] The galactomannan polymer derivative may be an amphoteric galactomannan polymer derivative having a net positive charge, which is obtained when the cationic galactomannan polymer derivative further comprises an anionic group.

[0049] Cationic non-guar galactomannans can have a mannose to galactose ratio of greater than 4:1, a molecular weight of 100,000 g / mol to 500,000 g / mol, a molecular weight of 50,000 g / mol to 400,000 g / mol, and a cationic charge density of 1 meq / g to 5 meq / g and 2 meq / g to 4 meq / g.

[0050] The shampoo composition may comprise at least 0.05% of the galactomannan polymer derivative by weight of the composition.The shampoo composition may comprise from 0.05% to 2% of the galactomannan polymer derivative by weight of the composition.

[0051] Cationic Starch Polymer Suitable cationic polymers may also be water-soluble cationically modified starch polymers. As used herein, the term "cationically modified starch" refers to starch to which cationic groups have been added before the starch is degraded to a smaller molecular weight, or to starch to which cationic groups have been added after the starch has been modified to achieve a desired molecular weight. The definition of the term "cationically modified starch" also includes amphoterically modified starch. The term "amphoterically modified starch" refers to a starch hydrolysate to which cationic and anionic groups have been added.

[0052] The shampoo compositions described herein may comprise cationically modified starch polymers in the range of 0.01% to 10% and / or 0.05% to 5% by weight of the composition.

[0053] The cationically modified starch polymers disclosed herein have a bound nitrogen percentage of 0.5% to 4%.

[0054] The cationically modified starch polymers can have a molecular weight of from 850,000 g / mol to 15,000,000 g / mol and from 900,000 g / mol to 5,000,000 g / mol.

[0055] Cationically modified starch polymers can have a charge density of 0.2 meq / g to 5 meq / g and 0.2 meq / g to 2 meq / g. Chemical modifications to achieve such charge densities can include adding amino and / or ammonium groups to the starch molecule. Non-limiting examples of such ammonium groups include substituents such as hydroxypropyltrimonium chloride, trimethylhydroxypropylammonium chloride, dimethylstearylhydroxypropylammonium chloride, and dimethyldodecylhydroxypropylammonium chloride. Further details are provided in Solarek, DB, *Cationic Starches in Modified Starches: Properties and Uses*, Wurzburg, OB, Ed., CRC Press, Inc. (Boca Raton, Fla.), 1986, pp. 113-125, which is incorporated herein by reference. Cationic groups can be added to the starch before it is degraded to smaller molecular weights, or the cationic groups can be added after such modification.

[0056] Cationically modified starch polymers may have a degree of substitution of cationic groups of 0.2 to 2.5. As used herein, the "degree of substitution" of a cationically modified starch polymer is the average number of hydroxyl groups on each anhydroglucose unit that are derivatized with a substituent. Because each anhydroglucose unit has three possible hydroxyl groups available for substitution, the maximum possible degree of substitution is 3. The degree of substitution is expressed on a molar average basis as the number of moles of substituent per mole of anhydroglucose unit. The degree of substitution can be determined by proton nuclear magnetic resonance spectroscopy ("NMR"), a method well known in the art. 1 The NMR can be determined using 1 H NMR. 1Examples of H NMR methods include those described in "Observation on NMR Spectra of Starches in Dimethyl Sulfoxide, Iodine-Complexing, and Solvating in Water-Dimethyl Sulfoxide," Qin-Ji Peng and Arthur S. Perlin, Carbohydrate Research, 160 (1987), 57-72; and "An Approach to the Structural Analysis of Oligosaccharides by NMR Spectroscopy," J. Howard Bradbury and J. Grant Collins, Carbohydrate Research, 71 (1979), 15-25.

[0057] The starch source before chemical modification can be selected from various sources, such as tubers, legumes, cereals, and grains. For example, the starch source can include corn starch, wheat starch, rice starch, waxy corn starch, oat starch, cassava starch, barley, waxy rice starch, gluten-like rice starch, sweet rice starch, amioca, potato starch, tapioca starch, oat starch, sago starch, sweet rice, or a mixture thereof. Suitable cationic modified starch polymers can be selected from degraded cationic corn starch, cationic tapioca, cationic potato starch, and a mixture thereof. Cationic modified starch polymers include cationic corn starch and cationic tapioca.

[0058] Starch may contain one or more additional modifications before or after degradation to smaller molecular weights. For example, these modifications may include cross-linking, stabilization, phosphorylation, and hydrolysis. Stabilization may include alkylation and esterification.

[0059] The cationically modified starch polymer may be included in the shampoo composition in the form of hydrolyzed starch (e.g., acid, enzymatic, or alkaline degradation), oxidized starch (e.g., peroxide, peracid, hypochlorite, alkali, or any other oxidizing agent), physically / mechanically degraded starch (e.g., by thermomechanical energy input in processing equipment), or combinations thereof.

[0060] Starch can be easily dissolved in water and can form a substantially translucent solution in water. The transmittance of the composition is measured by ultraviolet-visible ("UV / VIS") absorbance measurement. This measurement method uses a Gretag Macbeth Colorimeter Color to measure the absorbance or transmittance of UV / VIS light by a sample. A light wavelength of 600 nm has been shown to be suitable for characterizing the transparency of shampoo compositions.

[0061] Cationic copolymer of acrylamide monomer and cationic monomer The shampoo composition may include a cationic copolymer of acrylamide monomers and cationic monomers, the copolymer having a charge density of 1.0 meq / g to 3.0 meq / g. The cationic copolymer may be a synthetic cationic copolymer of acrylamide monomers and cationic monomers.

[0062] Suitable cationic polymers can include: (i) an acrylamide monomer of formula IX:

[0067] The cationic monomer can conform to the formula X, where v and v″ are each 3, v′=1, w=1, y=1, and X - is Cl - which forms the following structure of formula XII:

[0068] [ka] The structure of formula XII can be referred to as a triquat.

[0069] The acrylamide monomer can be either acrylamide or methacrylamide.

[0070] The cationic copolymer can be AM:TRIQUAT, which can be a copolymer of acrylamide and 1,3-propanediaminium, N-[2-[[[dimethyl[3-[(2-methyl-1-oxo-2-propenyl)amino]propyl]ammonio]acetyl]amino]ethyl]2-hydroxy-N,N,N',N',N'-pentamethyl-, trichloride. AM:TRIQUAT is also known as polyquaternium 76 (PQ76). AM:TRIQUAT can have a charge density of 1.6 meq / g and a molecular weight of 1,100,000 g / mol.

[0071] The cationic copolymer may comprise an acrylamide monomer and a cationic monomer, wherein the cationic monomer is selected from the group consisting of dimethylaminoethyl (meth)acrylate, dimethylaminopropyl (meth)acrylate, ditertiobutylaminoethyl (meth)acrylate, dimethylaminomethyl (meth)acrylamide, dimethylaminopropyl (meth)acrylamide; ethyleneimine, vinylamine, 2-vinylpyridine, 4-vinylpyridine; trimethylammonium ethyl (meth)acrylate chloride, trimethylammonium ethyl (meth)acrylate methyl sulfate, dimethylammonium ethyl (meth)acrylate benzyl chloride, 4-benzoylbenzyldimethylammonium ethyl acrylate chloride, trimethylammonium ethyl (meth)acrylamido chloride, trimethylammonium propyl (meth)acrylamido chloride, vinylbenzyl trimethylammonium chloride, diallyldimethylammonium chloride, and mixtures thereof.

[0095] The cationic polymers described herein can also help repair damaged hair, especially chemically treated hair, by providing a substitute hydrophobic F-layer. The microscopically thin F-layer provides natural weather resistance while helping to seal in moisture and prevent further damage. Chemical treatment damages the hair cuticle, causing the hair's protective F-layer to peel off. As the F-layer peels off, the hair becomes more hydrophilic. Application of lyotropic liquid crystals to chemically treated hair has been found to make the hair more hydrophobic, giving it the appearance and feel of untreated hair. Without being bound by any theory, it is believed that the lyotropic liquid crystal complex forms a hydrophobic layer or film that coats and protects the hair fiber in the same way that a natural F-layer protects hair. The hydrophobic layer can restore hair to a healthier state, generally resembling untreated hair. Lyotropic liquid crystals are formed by combining the synthetic cationic polymers described herein with the aforementioned anionic cleansing surfactant components of shampoo compositions.The charge density of the synthetic cationic polymers is relatively high.It should be noted that some synthetic polymers with relatively high cationic charge density do not form lyotropic liquid crystals, mainly due to their abnormal linear charge density.Such synthetic cationic polymers are described in International Publication No. 94 / 06403, which is incorporated by reference.The synthetic polymers described herein can be formulated into stable shampoo compositions that improve conditioning performance for damaged hair.

The polymers also have molecular weights of 1,000 g / mol to 5,000,000 g / mol, 10,000 g / mol to 2,000,000 g / mol, and 100,000 g / mol to 2,000,000 g / mol.

[0100] Techniques for analyzing the formation of complex coacervates are known in the art. For example, microscopic analysis of the composition at any selected dilution level can be used to determine whether a coacervate phase has formed. Such a coacervate phase can be identified as an additional emulsified phase in the composition. The use of dyes can help distinguish the coacervate phase from other insoluble phases dispersed in the composition. Further details regarding the use of cationic polymers and coacervates are disclosed in U.S. Pat. No. 9,272,164, which is incorporated herein by reference.

For example, an effective amount of the shampoo composition can be applied to wet hair or skin with water, and the composition can then be rinsed off. The effective amount can generally range from 1 g to 50 g and from 1 g to 20 g. Application to hair typically involves spreading the composition over the hair so that most or all of the hair comes into contact with the composition.

[0157] A method of treating hair or skin may include the steps of (a) wetting the hair or skin with water, (b) applying an effective amount of the shampoo composition to the hair or skin, and (c) rinsing the applied skin or hair with water. These steps may be repeated as many times as desired to achieve the desired cleansing and conditioning benefits.

[0158] The shampoo compositions described herein may be used to treat damaged hair, which may include permed hair, oxidatively dyed hair, and mechanically damaged hair.

[0159] The shampoo composition can be used as a liquid, solid, semi-solid, flake, gel in a pressurized container with added propellant, or in the form of a pump-action spray. The viscosity of the product can be selected to correspond to the desired form.

[0160] Test Method A. Cone and Plate Viscosity Measurement The viscosity of the examples was measured using a Brookfield Rheometer R / S Plus Cone / Plate Controlled Stress manufactured by Brookfield Engineering Laboratories (Stoughton, MA). The cone used (Spindle C-75-1) had a diameter of 75 mm and an angle of 1°. The viscosity was measured at a constant shear rate of 2 s -1 and temperature 26.5° C. The sample size is 2.5 mL and the total measurement read time is 3 minutes.

[0161] B.pH method First, calibrate your Mettler Toledo Seven Compact pH meter. To do this, power on the pH meter and wait 30 seconds. Next, remove the electrode from the storage solution, rinse it with distilled water, and carefully wipe the electrode with a scientific cleaning wipe, such as Kimwipe®. Immerse the electrode in a pH 4 buffer solution and press the calibrate button. Wait until the pH icon stops flashing and press the calibrate button again. Rinse the electrode with distilled water and carefully wipe the electrode with a scientific cleaning wipe. Next, immerse the electrode in a pH 7 buffer solution and press the calibrate button again. Wait until the pH icon stops flashing and press the calibrate button again. Rinse the electrode with distilled water and carefully wipe the electrode with a scientific cleaning wipe. Next, immerse the electrode in a pH 10 buffer solution and press the calibrate button again. Wait until the pH icon stops flashing and press the measure button. Rinse the electrode with distilled water and carefully wipe the electrode with a scientific cleaning wipe.

[0162] Immerse the electrode in the test sample and press the read button. Wait until the pH icon stops flashing and record the value.

[0163] C. Appearance method After the batch is finished, first transfer the batch to a storage container. Next, sample the batch in the glass vial. Then visually inspect the sample. If the background is clearly visible, record its appearance as transparent. If the background is visible but distorted or blurred, record it as translucent. If the background is not visible, record it as opaque.

[0164] D. Phase stabilization method After the batch is finished, first transfer the batch to a storage container. Next, sample the batch in the glass vial. Then visually inspect the sample. If the sample is homogeneous, record it as a single phase. If the sample has two or more distinct phases, record it as phase separated, including the number of phases present. The different phases will be visually different (change in haze, color, texture). These different phases will either sink to the bottom, be on top, or float.

[0165] E. Evaluation of hair switches This method describes how to evaluate a final product on a hair switch. First, the hair is wet for 15 seconds. Next, shampoo is applied to the hair switch at 0.1 grams of shampoo per gram of hair. Various attributes of the shampoo's performance during the wash are then evaluated. The hair switch is moved up and down for 30 seconds. During these 30 seconds, the following evaluations are made: 1.) Foaming Speed ​​- Rating of foaming speed (scale: 0 = slow to 10 = fast) 2.) Foaming Amount - A visual assessment of how much foaming occurred (scale: 0 = low to 10 = high)

[0166] Next, run water through the section and begin rinsing. Rinse for 30 seconds. As you rinse, assess the Rinse Feel / Rinse Count Drag. Immediately after wetting, use your non-dominant hand to perform a moderate back-and-forth motion from top to bottom between your thumb and two fingers. Count the number of strokes until you consistently feel two consecutive drags / skips in the middle of the hair section. This count is recorded as the Rinse Drag. You should perform one stroke per second up to a total of 20 strokes (scale: 1 = fast rinse / clean to 20 = slow rinse / dirty).

[0167] After rinsing for 30 seconds, the patient uses their non-dominant hand to work the hair back and forth between the thumb and two fingers, using moderate pressure, from top to bottom to remove any excess water. Repeated back and forth movements of the hairpiece assess the hair's cleanliness, which is recorded as a post-rinse cleanliness rating (scale: 0 = poor / dirty to 10 = excellent / clean).

[0168] F. Puff foaming method First, add water and bring it to the desired temperature of 37.5-38°C. Next, fluff the puff and wet it with water. Apply shampoo to the puff in a circular motion. Then, move the puff with the lathered product over the beaker. Next, squeeze the puff forward by rotating it halfway 10 times. Repeat this process of squeezing and rotating it halfway in the opposite direction 10 times. Finally, squeeze the puff to remove any remaining lather. The amount of lather generated is measured in the beaker.

[0169] G. Cylinder Whisk Method - Foam Volume Add 100 mL of water to a 1,000 mL graduated cylinder. Then add 0.5 g of shampoo. The graduated cylinder is placed on a rotating device. The cylinder is rotated 25 complete revolutions at a rate of 10 revolutions per 18 seconds to create foam, and then stopped in a horizontal, vertical position. A timer is set for 15 seconds to allow for drainage. After 15 seconds, record the foam height to the nearest 10 mL and measure the foam volume (including any water at the bottom and foam floating on top).

[0170] H.Kruss Whisk Method The KRUSS Dynamic Foam Analyzer is used to evaluate foaming. Shampoo and water are placed in the device at a dilution of 1 part shampoo to 9 parts water. Air passing through the chamber generates foam. The foaming rate, foam volume, and bubble size are recorded. [Example]
