Description

30 SOLID SURFACTANT COMPOSITION AND USE OF THE COMPOSITION Field of Invention [1] The present invention relates to surfactant compositions, especially aqueous surfactant compositions and solid surfactant compositions with a content of alpha-sulfo fatty acid disals and polysaccharides. Previous Technique [2] Anionic surfactants are some of the most widespread active interface compounds and, in addition to being used in detergents and cleaning products, they are also used for various purposes in the cosmetics field. The usual anionic surfactants, especially used in cosmetics, are alkyl ether sulfate salts (alkyl polyether sulfates, fatty alcohol polyglycol ether sulfates, in short also ether sulfates). They are distinguished by a strong foaming capacity, high cleaning power, low sensitivity to hardness and oiliness and are widely used for the production of cosmetic products, such as, for example, hair shampoos, bubble baths or shower gels, but also in dishwashing detergents. [3] For many current applications, in addition to a good active interface effect, other requirements are placed on anionic surfactants. High dermatological compatibility is required, particularly in cosmetics. In addition, adequate water solubility, good compatibility with as many active and auxiliary ingredients used in cosmetics as possible, good foaming ability and good thickenability are generally desired. Especially for hair care compositions, dermatological compatibility and ease of use are objectives of new developments. [4] In addition, there is a need for anionic surfactants that can be produced at least partially from biogenic sources. Petition 870260033686, dated 10 / 04 / 2026, p. 11 / 78 / 30 and, specifically, also renewable raw materials. Furthermore, there is also a need for surfactants that do not have alkoxylated groups, thus making the use of ethylene oxide, in particular, superfluous for their production. [5] US application 2012 / 208898 describes aqueous compositions for personal care comprising sulfonated fatty acid ester salts and / or sulfonated fatty acid salts in combination with alkyl betaines as hair care formulations. Sulfonated fatty acid ester salts are well-tolerated surfactants, but due to their good water solubility it is difficult to form solid surfactant compositions with these surfactants. [6] It was an objective of the invention to provide a skin cleansing composition that would provide an easy-to-rinse and smooth feeling to the skin, softness and less dryness of the skin after rinsing. Especially for hair treatment, another objective was to achieve a conditioning effect without stickiness and with a long drying time. Improved drying properties of surfactant compositions for hair care for time-saving use (fast drying effect on hair) are an important objective. [7] Anionic surfactants are very frequently used in solid compositions. Formerly, solid cleaning bars that were conventional soap bars contained alkali metal salts of fatty acids (soaps in the classical sense), but in recent years cleaning bars have also been made of surfactants. Soap-like bars consisting entirely of synthetic detergent compositions were called syndet bars, the combination of fatty acid salts with surfactants was marketed as combibars. Conventional soaps being fatty acid salts provide an alkaline environment due to hydrolysis in aqueous solution at a pH of 10.2-10.4, which results in damage to Petition 870260033686, dated 10 / 04 / 2026, page 12 / 78 / 30 epidermis, the skin's natural protection, which normally has an acidic pH of approximately 5.5-6.5. Destroying the skin's natural barrier through the continuous use of these surfactant soaps leads to poor skin tolerance with itching, dehydration, and cracking of the epidermis. In order to overcome these disadvantages, "refatting agents," such as fatty and oily ingredients selected from natural oils, mineral oil, petrolatum, stearic acid, or lanolin, or "moisturizers," for example, glycerin, urea, and sorbitol, have been incorporated into soap bars. These refatting agents often result in a sticky feel and increase drying time. Furthermore, the addition of these additives leads to the inconvenience of weak foaming and cleaning properties of the soaps.Furthermore, conventional soaps have undesirable characteristics such as foaming or curdling due to their incompatibility with hard water and the poor solubility of their calcium salts. [8] The same applies partially to common soap fillers used to reduce costs and improve handling of bars, providing sufficient firmness. Years ago, sodium silicate, talc, or borax were used as main components. However, these fillers are not very well tolerated, especially for sensitive skin. International Patent Application WO 92 / 07931 describes bars of common anionic surfactants and polysaccharides. Talc, clay, calcium carbonate, and dextrin are listed as possible fillers. [9] The preferred surfactants used in syndet bars were alkali metal salts of acyl isethionates, fatty alcohol sulfates or alkane sulfonates which are still the predominantly used surfactants in bars containing surfactants.

[10] US Patent No. 2,894,912 describes a detergent bar consisting of an alkali metal salt of acid esters Petition 870260033686, dated 10 / 04 / 2026, p. 13 / 78 / 30 isethionic; mixed aliphatic acids; a so-called detergent salt for foam enhancement, for example, alkyl aryl sulfonates; water; a superior fatty acid soap; and a superior fatty acid.

[11] US Patent 4,100,097 refers to a synthetic detergent bar consisting of coconut oil fatty acid ester of sodium isethionate and / or sodium lauryl sulfoacetate, paraffin, starch powder, dextrin, coconut oil fatty acid and water.

[12] The required amounts of synthetic detergents in surfactant bars often result in softness and low firmness, stickiness, manufacturing difficulties, cracking in the bars and poor foaming properties. In addition, the use of these surfactants is currently decreasing for environmental reasons and impurity-free substitutes of ethylene oxide and sulfates that are made from renewable resource raw materials are increasingly favored.

[13] The family of patents related to Patent Applications International patents WO 03 / 063819, WO 06 / 062665 and WO07 / 133582 describe a combination of C6 to C22 fatty acid salts, a polyhydric alcohol and a mixture of anionic surfactants comprising an alpha sulfonated alkyl ester and a sulfonated fatty acid. These compositions exhibit improved processing capability and improved after-skin feel properties. However, the high quantity of at least 40% by weight of a fatty acid soap still results in the disadvantages of conventional fatty acid salt soaps, and a primary objective was to avoid a large quantity of conventional soaps.

[14] Examples 1 to 5 of U.S. Patent 4861508 describe moldable detergent compositions comprising α-sulfolauric acid and myristic acid as an anionic surfactant, in addition to conventional alkali metal soaps.

[15] From the foregoing, it is evident that there is still a need for Petition 870260033686, dated 10 / 04 / 2026, page 14 / 78 / 30 solid surfactant compositions made of well-tolerated detergents that have a pH close to that of a person's skin and, in any case, exhibit good handling, foaming and cleaning properties. The processing of solid surfactant compositions should be easily possible. Therefore, another objective was to provide the anionic surfactant in the form of a composition containing a solid surfactant with good foaming properties, surfactant mildness, good compatibility with water hardness and increased firmness.

[16] Hair treatment with surfactant composition should also be possible in the form of solid surfactant compositions, these should show advanced foaming behavior during rinsing, a conditioning effect and improved drying time compared to commercially available surfactant compositions, for example, surfactant bars with sodium cocoyl isethionate. Description of the Invention

[17] The objective of the present invention was to provide improved surfactant compositions with a well-tolerable anionic surfactant content that are liquid aqueous surfactant compositions or solid compositions.

[18] This objective was solved by a surfactant composition comprising • one or more disals of alpha-sulfo fatty acids (A) of general formula (I), R1CH(SO3M1)COOM2 (I) wherein the radical R1 denotes a linear or branched alkyl or alkenyl radical with 6 to 16 carbon atoms and the radicals M1 and M2, independently of each other, are selected from the group H, Li, Na, K, Ca / 2, Mg / 2, ammonium and alkanolamine, • one or more polysaccharides (B) selected from the group consisting of dextrin and its derivatives, starch and its derivatives and cellulose and Petition 870260033686, dated 10 / 04 / 2026, p. 15 / 78 / 30 and its derivatives, where the following conditions apply: • if the surfactant composition comprises one or more ester sulfonates (E) of general formula (V), R2CH(SO3M7)COOR3(V) wherein the radical R2 is a linear or branched alkyl or alkenyl with 6 to 18 carbon atoms and the radical R3 is a linear or branched alkyl or alkenyl with 1 to 20 carbon atoms, where the radical R3 can logically be an alkenyl radical or be branched just above 3 carbon atoms, and the radical M7 is selected from the Li, Na, K, Ca / 2, Mg / 2, ammonium and alkanolamines group, it is the case that compounds (A) - based on the sum of compounds (A) and (E) - must be present in more than 50% by weight.

[19] Surfactant compositions are distinguished by an excellent foaming ability, in particular the initial foaming behavior. The initial foaming behavior plays a very important role for so-called rinse-off products, which should be understood as products that come into contact with the skin or hair during cleansing or hygiene, but are then washed off again (e.g., shower gels, bath formulations, shampoos, liquid soaps, etc.). In this sector, the highest possible foam volume is desired.

[20] In addition, surfactant compositions have hydrolysis stability in both the acidic and alkaline pH range and avoid constituents comprising ethylene oxide or propylene oxide building blocks for ecological reasons, as well as surfactants with sulfate groups to improve skin and mucous membrane tolerability.

[21] Surfactant compositions also have a storage stability at room temperature (23 °C) of at least 8 Petition 870260033686, dated 10 / 04 / 2026, page 16 / 78 / 30 weeks without any visible changes (e.g., turbidity, phase separations, discoloration, and the like) occurring and without changes in viscosity or changes in the resulting chemical composition.

[22] The surfactant compositions of the invention are aqueous surfactant compositions, which are liquid aqueous surfactant compositions or solid compositions.

[23] The amount of water in the solid composition is 1% to 20% by weight, preferably 5% to 15% by weight, more preferably 7% to 15% by weight. The amount of water in the liquid aqueous compositions is greater than 30% by weight, preferably greater than 40% by weight, more preferably greater than 50% by weight based on the aqueous composition.

[24] Due to poor skin tolerability, it is an objective to reduce the amount of anionic surfactants in personal and household hygiene products. The surfactant compositions of the present invention shall comprise less than 40% by weight, comprising less than 25% by weight, more preferably less than 15% by weight of anionic surfactants other than compounds (A) and (C) based on the weight of the composition. Often, other anionic surfactants are conventional soaps, which are alkaline salts of fatty acids. In the case of solid compositions, the fatty acid is primarily a C12 to C22 saturated fatty acid, especially stearic acid. Compositions comprising salts of long-chain fatty acids, especially stearic acid, are difficult to handle due to their incompatibility with water hardness, poor foaming properties, foaming or curdling characteristics, and poor skin tolerability resulting from the alkaline pH value.Therefore, the surfactant compositions of the present invention should comprise less than 30% by weight, more preferably less than 20% by weight of stearic acid fatty acid salts based on the weight of the composition.

Petition 870260033686, dated 10 / 04 / 2026, p. 18 / 78 / 30

[27] Solid compositions comprising anionic surfactants with good foaming properties must have improved anti-frizz performance and faster drying performance to be suitable for hair treatment, preferably as shampooing hair care compositions. Surprisingly, solid compositions comprising alpha-sulfo fatty acid disals and selected polysaccharides from the group consisting of dextrin and its derivatives, starch and its derivatives and cellulose and its derivatives exhibit improved anti-frizz performance and have a faster drying performance after hair treatment.

Preferably, the solid composition comprises less than 30% by weight, more preferably less than 20% by weight of stearic acid fatty acid salts based on the weight of the composition. The compounds (A)

[30] Compounds (A), which are referred to in the context of the present invention as alpha-sulfo fatty acid disals, are mandatory for the aqueous and solid surfactant compositions according to the invention. They have the formula (I) mentioned above. R1CH(SO3M1)COOM2(I) in which the radical R1 denotes a linear or branched alkyl or alkenyl radical with 6 to 16 carbon atoms and the radicals M1 and M2, independently of each other, are selected from the H, Li, Na, K, Ca / 2, Mg / 2, ammonium and alkanolamine groups. The particularly preferred alkanolamines of the invention are Monoethanolamine, Diethanolamine, Triethanolamine and Mono-Isopropanolamine.

[32] In one embodiment, the condition applies that the fraction of compounds (A) in the surfactant compositions in which the radical R1 is an alkenyl radical - based on the total amount of compounds (A) - is 3% by weight or less.

[33] In a preferred embodiment, the radical R1 in formula (I) means a saturated linear radical with 10 to 16 carbon atoms, wherein, in relation to compounds (A), it is the case that the fraction of compounds (A) in which the radical R1 is a decyl and / or dodecyl radical - based on the total amount of compounds (A) - is more than 70% by weight, preferably more than 80% by weight, more preferably more than 90% by weight and in particular more than 95% by weight.

[36] Solid compositions generally comprise 10 to 90% by weight of alpha-sulfo fatty acid disals (A), preferably 20 to 70%, more preferably 30 to 50% by weight of alpha-sulfo fatty acid disals based on the weight of the composition.

[37] Compounds (A) can be prepared by all known methods suitable to a person skilled in the art. A particularly preferred method of preparation here is the sulfation of the corresponding carboxylic acids. Here, the corresponding carboxylic acid and, in Petition 870260033686, dated 10 / 04 / 2026, page 22 / 78 / 30 in particular, the corresponding fatty acids are reacted with gaseous sulfur trioxide, the sulfur trioxide preferably being used in an amount such that the molar ratio of SO3 to fatty acid is in the range of 1.0:1 to 1.1:1. The crude products thus obtained, which are products of acid sulfonation, are then partially or totally neutralized, complete neutralization with aqueous NaOH being preferred. If desired, purification steps and / or bleaching (to adjust the desired pale color of the products) can also be carried out.

[38] In a particularly preferred embodiment, compounds (A) are used in technical grade form. This means that the corresponding carboxylic acids, in particular native fatty acids, are sulfonated with gaseous sulfur trioxide, as a result of which, after partial or complete neutralization of the resulting acid sulfonation products, a mixture of compounds (A), (C) and (D) results. By virtue of the corresponding adjustments of the reaction parameters (in particular the molar ratio of carboxylic acid and sulfur trioxide, and also the reaction temperature), it is possible to control the ratio of compounds (A), (C) and (D). Compounds (C) and (D) are described below in the chapter “Preferred Embodiments”.

The compounds (B)

[40] The function of compound (B) in the aqueous surfactant composition is based on its conditioning and hair care effects for liquid and solid compositions and its filling and forming properties for solid compositions.

[41] Liquid aqueous compositions generally comprise 0.1 to 10% by weight of polysaccharides, preferably 0.2 to 5%, more preferably 1 to 3% by weight of polysaccharides based on the weight of the composition.

[42] Solid aqueous compositions generally comprise from to 60% by weight of polysaccharides, preferably from 5 to 50%, more preferably 15 to 40% by weight of polysaccharides based on the weight of the composition.

[43] For solid surfactant compositions, compounds B are filler materials. The function of the filler material is to allow the use of surfactants in a solid form, to strengthen the composition, to increase the wear rate, firmness and sensory feel of the composition, decreasing the cost, without compromising the foaming performance of the anionic surfactant.

[44] Preferred filler materials for solid surfactant compositions are polysaccharide powder, such as dextrin and its derivatives, starch and its derivatives, cellulose and its derivatives.

[45] The compounds (B), which are referred to in the context of the present invention as polysaccharides, are selected from the group consisting of dextrin and its derivatives, starch and its derivatives, cellulose and its derivatives, at least one of which is required for the surfactant compositions according to the invention. Starch and its derivatives Petition 870260033686, dated 10 / 04 / 2026, p. 24 / 78 / 30 Starch

[46] The binder / filler component may be an untreated starch or a modified powdered hydrolyzed starch or a derivative. In solid compositions, this should be present in an amount ranging from about 5% to about 20% by weight and preferably in an amount ranging from about 7% to about 12% by weight.

[47] Starch derivatives used in food and cosmetics production, such as oxidized starch, monostamido phosphate, diamido phosphate, phosphated diamido phosphate, acetylated diamido phosphate, acetylated starch, acetylated diamido adipate, hydroxypropyl starch, hydroxypropyl distarka phosphate are possible filler and binder materials as well.

[48] ​​It is particularly preferred to use unsubstituted potato, wheat and / or corn starch which can be used in untreated form or preferably in digested form, i.e. partially hydrolyzed. Cellulose and its derivatives

[49] In the food and cosmetics industry, cellulose ethers are frequently used as thickeners, in addition to this function they are also used as fillers and binders.

[50] Suitable cellulose derivatives are, for example, cellulose ethers. Cellulose ethers are manufactured by replacing hydrogen atoms in the hydroxyl groups of cellulose with alkyl and / or arylalkyl groups; these alkyl and / or arylalkyl groups may be further substituted with nonionic, anionic, cationic or non-ionic groups. The alkyl groups are typically linear or branched C1-C8 alkyl groups. The preferred alkyl group is a C1-C4 alkyl group, examples being methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl or tert-butyl. The alkyl group may be substituted with an aromatic radical to form the arylalkyl group, such as Petition 870260033686, dated 10 / 04 / 2026, page 25 / 78 16 / 30 a phenyl radical, for example. A preferred arylalkyl group is benzyl. The alkyl or arylalkyl group can be functionally substituted, for example, by hydroxyl, carboxyl or carboxylate groups. Where carboxylate groups are present, corresponding counter-ions are also present, examples being alkali metal ions such as sodium or potassium, or ammonium ions. It is also possible to use mixed cellulose ethers, which contain more than one type of functionally substituted alkyl, arylalkyl or alkyl groups.

[51] Preferred hydrophilic polymeric cellulose derivatives are methyl-, ethyl-, propyl-, carboxymethyl-, hydroxyethyl-, hydroxypropyl-, hydroxypropylmethyl-, ethylmethylcellulose-, methyl-hydroxyethyl-, methyl-hydroxybutyl-, ethyl-hydroxyethyl- and / or carboxymethyl-hydroxyethylcellulose. Among the carboxymethylcelluloses, sodium carboxymethylcellulose, cross-linked sodium carboxymethylcellulose or enzymatically hydrolyzed carboxymethylcellulose. Dextrins and their derivatives

[52] Dextrins and their derivatives include dextrins, maltodextrins and cyclodextrins. The most preferred compounds (B), in the context of the present invention, are dextrins. They have the formula (II) mentioned above, where n - the average degree of polymerization - is an integer between 3 and 200, preferably between 5 and 100, and most preferably between 10 and 40.

[53] Dextrins are a group of low molecular weight carbohydrates that can be obtained by hydrolyzing D-glucose units to form starch, linked by an α-(l —> 4) linkage starting with an α-(l —> 6) glycosidic linkage.

[54] Preferably, they have a dextrose equivalent between 1 and 30%, preferably between 1% and 13% based on 100% dextrose (glucose). Petition 870260033686, dated 10 / 04 / 2026, page 26 / 78 / 30 Dextrose equivalent (DE) is a measure of the amount of reducing sugars present in a sugar product, expressed as a percentage on a dry basis relative to dextrose. The dextrose equivalent gives an indication of the average degree of polymerization (DP) for starch sugars, and is inversely related to molecular weight. The degree of polymerization (DP) is an indicator of the degree of hydrolysis; unhydrolyzed starch has a DE of 0, while glucose has a DE value of 100.

[55] These polysaccharides are produced from starch using enzymes such as amylases or by dry heating under acidic conditions (pyrolysis or roasting). Industrial production of dextrins is generally carried out by acid hydrolysis of potato starch.

[56] Finished dextrins are a very fine powder in various colors, from pure white to brown. Depending on their molecular weight and color, three main types of dextrins are distinguished: white dextrins, canary or yellow dextrins, and British gums. British gums are dextrins with the highest molecular weight with an average degree of polymerization of about 20 and strong adhesive properties, yellow dextrins are the lowest in molecular weight, while white dextrins have a molecular weight between the other types. They are frequently used in adhesives and coatings that come into contact with food products.

[57] Although not the preferred dextrins, maltodextrins can also be included as polysaccharides and dextrin derivatives in the composition. They are composed only of α-(1^4) linkage glucose and have an average degree of polymerization between 10 and 20 and a dextrose equivalent of 3 to 20%, preferably 10 to 20%.

[58] Cyclodextrin can be any of the known cyclodextrins, such as unsubstituted cyclodextrins containing six to twelve glucose monomers, especially alpha-, beta- and gamma-cyclodextrins and / or their derivatives and / or mixtures thereof. Alpha, beta and gamma cyclodextrins contain Petition 870260033686, dated 10 / 04 / 2026, page 27 / 78 / 30 6, 7, and 8 glucose monomer units, respectively, arranged in a donut-shaped ring. Examples of cyclodextrin derivatives suitable for use in the present invention include methyl beta-cyclodextrin, hydroxyethyl beta-cyclodextrin, and hydroxypropyl beta-cyclodextrin with varying degrees of substitution. Water-soluble cyclodextrin derivatives are preferred. Preferably, at least a major portion of the cyclodextrins is alpha, beta, and / or gamma-cyclodextrins, more preferably alpha and beta-cyclodextrins. A particularly preferred cyclodextrin for use in the present invention is beta-cyclodextrin. Mixtures of these cyclodextrins are also preferred.

[59] In the present invention, the amount of dextrins is responsible for the improved drying effect, a conditioning effect of the aqueous surfactant compositions without compromising the foaming performance of the anionic surfactant and the processability of the solid surfactant compositions.

[60] Liquid aqueous compositions generally comprise 0.1 to 10% by weight of dextrins, preferably 0.2 to 5%, more preferably 1 to 3% by weight of dextrins based on the weight of the composition. It has been shown to improve the drying speed of hair when used for hair cleansing and, depending on its dextrose equivalent, may improve the viscosity increase of liquid aqueous compositions.

[61] Solid aqueous compositions generally comprise from 5 to 50% by weight of dextrins, more preferably from 15 to 40%, and most preferably between 25 and 35% by weight of dextrins based on the weight of the composition. Dextrins allow the processing of solid compositions with alpha-sulfo fatty acid disals, they enable the shaping of the solids.

Manufacturing of solid surfactant bars

[86] The preparation of solid surfactant bars comprises the following steps: Step 1: Production of solid surfactant composition in wire form: 1. Citric acid was dissolved in demineralized water.

[87] 2. Texapon SFA powder and polysaccharide powder were first mixed in a paddle mixer (L20, Loedige Process Technology, Gebrüder Lodige Maschinenbau, Paderborn, Germany) at 30 RPM for 3-5 min. Inert gas (e.g., nitrogen gas) was used as a shielding gas in the mixer to prevent dust explosion.

[88] 3. The citric acid solution was then added to the mixer by feeding it with a pressure nozzle at 30 RPM for 20-30 min. The mixer was then run at 50-100 RPM for 20-30 min to form a wet paste. The pH of the paste (10% by weight solution in water) after mixing was 5-6.

[89] 4. The paste was subsequently mixed in a Mix-Muller (LG, Simpson Technologies, Euskirchen, Germany) at 15-30 RPM for 20-30 min and then

[90] 5. extruded in an extruder (LSRE 75 R, Sela Maschinen GmbH, Harbke, Germany) with 3 mm dies at 3-10 RPM extrusion speed to produce SFA yarns.

[91] 2nd stage: Production of bars from solid surfactant wires:

[92] The clumps formed on the wires were ground in a three-roll mill (Weber & Seelánder, Harbke, Germany) twice Petition 870260033686, dated 10 / 04 / 2026, page 34 / 78 / 30 for obtaining solid surfactant sheets.

[93] Solid surfactant sheets were placed in a soap bar extruder (Weber & Seeländer, Sela-Maschinen GmbH, Harbke, Germany) and pressed to obtain solid surfactant bars. 3. Anti-softness performance test method

[94] The soap bar was immersed in a 250 ml beaker, which is filled with 250 ml of demineralized water at 22 °C ± 2 °C (Figure 1: apparatus for anti-softness performance test method). The bar was immersed in the water by about 4 cm. The length (a) and width (b) of the bottom surface were measured for the calculation of the soft surface (A = a*b).

[95] After 2 hours of immersion, the bar was removed from the water, carefully shaken to dislodge any excess water and weighed (W1).

[96] The paste was then removed by carefully scraping with a plastic scraper and the scraped bars were wiped with a paper towel and dried overnight before determining the thermal weight (W2).

[97] The pope's performance was calculated: Softness percentage % = (W2 - W0) / W0 • W0 = Weight of the bar before immersion • W2 = Weight of the bar after 2 hours of immersion, removal of the paste, and overnight drying

[98] For hair care applications, one of the main performances is foaming, but softness is an important additional property. If the anti-softness value is too low, the bar will be too hard and difficult to apply to the hair. If the anti-softness value is too high, the bar will be too soft and easy to dissolve in water. The range for the best percentage softness value of solid surfactant bars was 5% - 40%, preferably 15% - 25%. 4. Foam Test Petition 870260033686, dated 10 / 04 / 2026, page 35 / 78 / 30 Foam Brushing Method

[99] 1. Grind the soap bar in the automatic household grinding machine to obtain a particle size of the ground powders from 20 µm to 3000 µm.

[100] 2. Add 0.15g of powdered soap and 14.85g of water to the 50 ml test tube and gently shake for 1 min to achieve a homogeneous dispersion.

[101] Place the tubular brush in the cylinder and brush vertically for 30 rounds inside the cylinder to create foam.

[102] 3. Remove the brush from the cylinder and read the foam height. Drying speed test Hair drying test protocol

[103] 1. Pre-treatment of hair strands.

[104] IHIP standard hair strands, Chinese hair, 15 cm / 2 g, bundled and glued at the top. The hair strands have been cleaned and bleached.

[105] 2. Weigh the hair.

[106] 3. Rinse hair for 1 minute at a water flow rate of 1L / min, 38°C, comb once with the wide side. Then, remove excess water with the middle and index fingers 3 times. Weigh wet hair (keep the initial water content at 75% of the dry hair weight).

[107] 4. Place the hair strands in the special tray, treat with a certain amount of the product and brush evenly for 30s on each side. Then, incubate for a total time of 3 minutes.

[108] 5. For the washing process, rinse the hair again for 1 minute at a water flow rate of 1L / min, 38 °C, remove excess water with the medium and indicator 3 times. Weigh the wet hair with product (maintain the initial water increase at 75% of the dry hair weight). Petition 870260033686, dated 10 / 04 / 2026, page 36 / 78 / 30
