Description

[Technical Field]

[0001] The present invention relates to a method for improving dandruff prevention by using a booster composition in combination with a hair care composition. [Background technology]

[0002] For many years, anti-dandruff shampoos have been widely used to treat dandruff and cleanse hair and scalp, but there is a need for improved anti-dandruff shampoos. Some consumers, despite suffering from dandruff, remain hesitant to use anti-dandruff shampoos because they dislike one or more aspects of typical anti-dandruff shampoos (i.e., hair feel, scent, etc.). Many consumers do not want to discontinue their preferred cosmetic shampoo used for hair benefits. Today's cosmetic shampoos provide hair benefits such as shine, feel, and appearance, but they cannot eliminate flakes or dandruff. Some consumers mix anti-dandruff shampoos with their preferred cosmetic shampoos when dandruff reduction is needed, but this does not deliver enough anti-dandruff active ingredients to the scalp and often results in an undesirable experience lacking one or more important attributes such as hair feel, combability, excessive cleansing, or scent. This practice dilutes the desired function of both the cosmetic shampoo and the anti-dandruff shampoo. Essentially, a noticeable anti-dandruff effect for consumers needs to be delivered from about one-third the dosage of standard anti-dandruff shampoos sold today. Hair care compositions containing low concentrations of surfactants with anti-dandruff active ingredients have been found, surprisingly, to achieve the improved adhesion efficiency necessary to provide consumers with noticeable anti-dandruff protection when mixed with cosmetic shampoos. Such compositions are known as anti-dandruff boosters or boosters. [Overview of the Initiative] [Means for solving the problem]

[0003] A method for using a booster in combination with a hair care composition to provide anti-dandruff activity, wherein the booster contains a scalp care active substance, the hair care composition does not contain a scalp care active substance, the booster contains about 5% to about 7% of one or more surfactants, and the adhesion of the scalp care active substance is greater than about 0.5 ug / cm2. [Brief explanation of the drawing]

[0004] [Figure 1] This graph shows the range of conditioning power versus cleansing power of conventional cosmetic shampoos, and the adhesion efficiency of the present invention. [Figure 2] This graph shows the difference in adhesion efficiency between leaving a conventional cosmetic shampoo + booster mixture on the scalp for 3 minutes and leaving it for 30 seconds. [Modes for carrying out the invention]

[0005] Unless otherwise specified, all percentages and ratios used herein are based on the weight of the whole composition. Unless otherwise specified, all measurements are understood to be performed under ambient conditions, where “ambient conditions” means conditions of approximately 25°C, approximately 1 atmosphere, and approximately 50% relative humidity. All numerical ranges include narrower ranges, and the upper and lower range limits described can be combined to create further ranges not explicitly described.

[0006] The compositions of the present invention include, essentially consist of, or comprise the essential components and optional components described herein. As used herein, “essentially consist of” means that a composition or component may include additional components, but only if the additional components do not substantially alter the basic and novel properties of the claimed composition or method.

[0007] As used in relation to the composition, "apply" or "apply" means applying or spreading the composition of the present invention onto keratinous tissue such as hair.

[0008] "Dermatologically acceptable" means that the described composition or component is suitable for use in contact with human skin tissue without excessive toxicity, incompatibility, instability, allergic reaction, etc.

[0009] "A safe and effective amount" means an amount of a compound or composition sufficient to significantly induce a beneficial effect.

[0010] This specification specifically points out and clearly claims the invention in the "claims", but the invention is considered to be better understood from the following description.

[0011] As used herein, the term "fluid" includes liquids and gels.

[0012] As used herein, the articles including "a" and "an" are understood to mean one or more of the claims or the things described when used in the claims.

[0013] As used herein, "comprising" means that other steps and other raw materials that do not affect the final result can be added. This term encompasses the terms "consisting of" and "consisting essentially of".

[0014] As used herein, "mixture" means a simple combination of materials and any compounds that can result from these combinations.

[0015] As used herein, "molecular weight (molecular weight or Molecular weight)" refers to the weight-average molecular weight unless otherwise specified. The molecular weight is measured using gel permeation chromatography ("gel permeation chromatography, GPC"), an industrial standard method.

[0016] When a range of quantities is given, it should be understood that these represent the total amount of the component in question in the composition, or, if more than one component falls within the defined range, the total amount of all components in the composition that conform to that definition.

[0017] For example, if a composition contains 1% to 5% aliphatic alcohols, a composition containing 2% stearyl alcohol and 1% cetyl alcohol, and no other aliphatic alcohols, would fall within this range.

[0018] The amount of each specific component or mixture thereof listed below may account for a maximum of 100% (or 100%) of the total amount of components in the booster.

[0019] As used herein, "personal care composition" includes products such as shampoos, shower gels, liquid hand washes, hair dyes, facial cleansers, and other surfactant-based liquid compositions.

[0020] As used herein, the terms “include,” “includes,” and “including” are understood to mean “comprise,” “comprises,” and “comprising,” respectively, in an unrestricted sense.

[0021] All percentages, parts, and proportions are based on the total weight of the compositions of the present invention unless otherwise specified. All such weights relating to the listed components are based on their activity concentrations and therefore do not include carriers or by-products that may be present in commercially available materials.

[0022] Unless otherwise noted, all concentrations of components or compositions refer to the active portion of that component or composition, excluding impurities that may be present in the commercially available source of such components or compositions, such as residual solvents or by-products.

[0023] It should be understood that all maximum numerical limits given throughout this specification include all lower numerical limits as if they were explicitly stated herein. All minimum numerical limits given throughout this specification include all higher numerical limits as if they were explicitly stated herein. All numerical ranges given throughout this specification include all narrow numerical ranges that fall within such broad numerical ranges as if they were explicitly stated herein.

[0024] How to use In this invention, the booster can be placed in one hand, then combined with the hair care composition in the second hand, mixed together, and then applied to the hair / scalp. Alternatively, the hair care composition can be applied to the hair / scalp, followed by the booster, which can then be mixed and lathered together with the hair care composition. The booster can be applied to the hair / scalp alone without being combined with the hair care composition. The booster can be placed in the hair care composition container and co-mixed before application to the hair / scalp.

[0056] Similarly, tertiary alkylamine oxides, including lauramine oxide and cocamine oxide, are also suitable for use herein.

[0057] Non-limiting examples of other anionic, amphoteric, amphoteric, and nonionic additional surfactants suitable for use as boosters are described in McCutcheon's "Emulsifiers and Detergents, 1989 Annual" (published by MCPublishing Co.), and U.S. Patents 3,929,678, 2,658,072, 2,438,091, and 2,528,378, which are incorporated herein by reference in their entirety.

[0058] A suitable surfactant combination contains an average weight percent of alkyl branching of about 0.5% to about 30% by weight, or about 1% to about 25% by weight, or about 2% to about 20% by weight. The surfactant combination can have a cumulative average weight percent of C8-C12 alkyl chain length of about 7.5% to about 25% by weight, or about 10% to about 22.5% by weight, or about 10% to about 20% by weight.

These cationic polymers may include at least one of the following: (a) cationic guar polymer, (b) cationic non-guar-galactomannan polymer, (c) cationic tapioca polymer, (d) cationic copolymer of acrylamide monomer and cationic monomer, and / or (e) synthetic non-crosslinked cationic polymer which may or may not form a lyotropic liquid crystal when combined with a detergent surfactant, and (f) cationic cellulose polymer. Furthermore, the cationic polymers may be mixtures of cationic polymers.

[0060] The booster may contain a cationic guar polymer, which is a cationically substituted galactomannan (guar) gum derivative. The guar gum used in the preparation of these guar gum derivatives is typically obtained as a naturally occurring material from the seeds of the guar plant. The guar molecule itself is a linear mannan with branched segments at regular intervals, where single-membered galactose units alternate on mannose units. The mannose units are linked to each other by β(1-4) glycosidic bonds. The galactose branching occurs via α(1-6) bonds. Cationic derivatives of guar gum are obtained by the reaction between the hydroxyl group of polygalactomannan and a reactive quaternary ammonium compound. The degree of substitution of the cationic group on the guar structure must be sufficient to provide the required cationic charge density described above.

[0061] In the present invention, the cationic polymer may include, but is not limited to, a cationic guar polymer having a weight-average molecular weight of 2.2 million g / mol, or about 150,000 to about 2.2 million g / mol, or about 200,000 to about 2.2 million g / mol, or about 250,000 to about 2.5 million g / mol, or about 300,000 to about 1.2 million g / mol, or about 700 million to less than 1 million g / mol. Furthermore, the cationic guar polymer may have a charge density of about 0.2 to about 2.2 meq / g, or about 0.3 to about 2.0 meq / g, or about 0.4 to about 1.8 meq / g, or about 0.5 meq / g to about 1.8 meq / g.

[0062] Cationic guar polymers may have a weight-average molecular weight of less than about 150 g / mol and a charge density of about 0.1 meq / g to about 2.5 meq / g. Cationic guar polymers may have a weight-average molecular weight of less than 900,000 g / mol, or about 150,000 to about 800,000 g / mol, or about 200,000 to about 700,000 g / mol, or about 300,000 to about 700,000 g / mol, or about 400,000 to about 6. Cationic guar polymers may have charge densities of approximately 0.2 to approximately 2.2 meq / g, or approximately 0.3 to approximately 2.0 meq / g, or approximately 0.4 to approximately 1.8 meq / g, or approximately 0.5 meq / g to approximately 1.5 meq / g.

[0063] Cationic guar polymers may be formed from quaternary ammonium compounds. Quaternary ammonium compounds for forming cationic guar polymers can conform to general formula 1.

[0068] [ka] In the formula, R 8 It is guar gum, and R 4 , R 5 , R 6 , and R 7 As defined above, Z is a halogen. Cationic guar polymers can conform to formula 5.

[0069] [ka]

[0070] Suitable cationic guar polymers include cationic guar gum derivatives such as guar hydroxypropyltrimonium chloride. Cationic guar polymers can be guar hydroxypropyltrimonium chloride. Specific examples of guar hydroxypropyltrimonium chloride include the Jaguar® series, commercially available from Solvay, such as Jaguar® C-500. Jaguar® C-500 has a charge density of 0.8 meq / g and a molecular weight of 500,000 g / mol. Another suitable guar hydroxypropyltrimonium chloride is guar hydroxypropyltrimonium chloride, available from Solvay as Jaguar® Optima, which has a charge density of approximately 1.3 meq / g and a molecular weight of approximately 500,000 g / mol.

[0071] The booster of the present invention may include a galactomannan polymer derivative having a monomer-to-mannan mannose-to-galactose ratio greater than 2:1, and this galactomannan polymer derivative is selected from the group consisting of cationic galactomannan polymer derivatives and amphoteric galactomannan polymer derivatives 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.

[0072] Galactomannan polymers are found in the endosperm of leguminous plant seeds. Galactomannan polymers are composed of a combination of mannose monomers and galactose monomers. A galactomannan molecule is a linear mannan in which individual galactose units on a specific mannose unit are branched at regular intervals. The mannose units are linked to each other by β(1-4) glycosidic bonds. Galactose branching occurs via α(1-6) bonds. The mannose monomer to galactose monomer ratio varies depending on the plant species and is also influenced by climate. The non-guar galactomannan polymer derivatives of the present invention have a mannose to galactose ratio greater than 2:1 on a monomer-to-monomer basis. A preferred mannose to galactose ratio may be greater than about 3:1, and a mannose to galactose ratio may be greater than about 4:1. Analysis of the mannose to galactose ratio is well known in the art and is typically based on the measurement of galactose content.

[0073] The gums used in the preparation of non-guar-galactomannan polymer derivatives are typically obtained from naturally occurring materials such as plant seeds or beans. Examples of various non-guar-galactomannan polymers include, but are not limited to, tara gum (3 parts mannose / 1 part galactose), locust bean or carob (4 parts mannose / 1 part galactose), and cassia gum (5 parts mannose / 1 part galactose).

[0074] Non-guar galactomannan polymer derivatives may have molecular weights ranging from approximately 1,000 to approximately 10,000,000 and / or approximately 5,000 to approximately 3,000,000.

[0075] The booster of the present invention may also include a galactomannan polymer derivative having a cation charge density of about 0.5 meq / g to about 7 meq / g. This galactomannan polymer derivative may have a cation charge density of about 1 meq / g to about 5 meq / g. The degree of substitution of cationic groups to the galactomannan structure must be sufficient to yield the required cation charge density.

[0076] Galactomannan polymer derivatives may also be cationic derivatives of non-guar galactomannan polymers, which are obtained by the reaction of a hydroxyl group of a polygalactomannan polymer with a reactive quaternary ammonium compound. Suitable quaternary ammonium compounds for use in forming cationic galactomannan polymer derivatives include those conforming to the general formulas 1 to 5 defined above.

[0077] The cationic non-guargalactomannan polymer derivative formed from the above reagents has a general formula of 6,

[0078] [ka] In the formula, R is represented by the formula, where R is gum. The cationic galactomannan derivative can be gum hydroxypropyltrimethylammonium chloride, which can be represented more specifically by the following general formula 7.

[0079] [ka]

[0080] Alternatively, the galactomannan polymer derivative may be an amphoteric galactomannan polymer derivative having a net positive charge, which can be obtained when the cationic galactomannan polymer derivative further contains an anionic group.

[0081] Cationic non-guargalactomannan can have a mannose-to-galactose ratio greater than approximately 4:1, molecular weights of approximately 1,000 g / mol to approximately 10,000,000 g / mol, and / or approximately 50,000 g / mol to approximately 1,000,000 g / mol, and / or approximately 100,000 g / mol to approximately 900,000 g / mol, and / or approximately 150,000 g / mol to approximately 400,000 g / mol, and cation charge densities of approximately 1 meq / g to approximately 5 meq / g, and / or 2 meq / g to approximately 4 meq / g, and can be obtained from the plant Cassia.

[0082] The booster may contain a water-soluble cationic-modified starch polymer. As used herein, the term “cationically modified starch” refers to starch to which cationic groups have been added before it is broken down to a smaller molecular weight, or to starch to which cationic groups have been added after it has been modified to reach a desired molecular weight. The definition of “cationically modified starch” also includes amphoteric modified starch. The term “amphoteric modified starch” refers to starch hydrolysates to which cationic and anionic groups have been added.

[0083] The cation-modified starch polymers disclosed herein have a bound nitrogen percentage of about 0.5% to about 4%.

[0084] The cation-modified starch polymer used in the booster may have a molecular weight of approximately 850,000 g / mol to approximately 1,500,000 g / mol, and / or approximately 900,000 g / mol to approximately 1,500,000 g / mol.

[0085] The booster may include a cationic modified starch polymer with a charge density of approximately 0.2 meq / g to approximately 5 meq / g and / or approximately 0.2 meq / g to approximately 2 meq / g. Chemical modifications to obtain such charge densities include, but are not limited to, the addition of amino and / or ammonium groups to the starch molecule. Non-limiting examples of these ammonium groups include substituents such as hydroxypropyltrimonium chloride, trimethylhydroxypropylammonium chloride, dimethylstearylhydroxypropylammonium chloride, and dimethyldodecylhydroxypropylammonium chloride. See Solarek, DB, Cationic Starches in Modified Starches: Properties and Uses, Wurzburg, OB, Ed., CRC Press, Inc., Boca Raton, Fla. 1986, pp. 113-125. The cationic group may be added to the starch before it is broken down to a smaller molecular weight, or it may be added after such modification.

[0086] Cationically modified starch polymers generally have a degree of cationic substitution of approximately 0.2 to approximately 2.5. As used herein, the “degree of substitution” of a cationically modified starch polymer is an average measure of the number of hydroxyl groups on each glucose anhydride unit that is derivatized by substituents. Since each glucose anhydride 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 basis as the number of moles of substituents per mole of glucose anhydride units. The degree of substitution can be determined using proton nuclear magnetic resonance spectroscopy ("sup.1H NMR"), a method well known in the art. Suitable sup.1H 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.

[0087] The starch source before chemical modification can be selected from a variety of sources, including tubers, legumes, cereals, and grains. Non-limiting examples of starches from this source include corn starch, wheat starch, rice starch, waxy corn starch, oat starch, cassava starch, waxy barley, waxy rice starch, glutenous rice starch, amioca, potato starch, tapioca starch, oat starch, sago starch, glutinous rice, or mixtures thereof.

[0088] Cationically modified starch polymers can be selected from decomposed cationic corn starch, cationic tapioca, cationic potato starch, and mixtures thereof. Alternatively, cationically modified starch polymers are cationic corn starch and cationic tapioca.

[0089] Starch may undergo one or more additional modifications before or after being broken down into smaller molecular weight molecules. Examples of these modifications include crosslinking, stabilization reactions, phosphorylation reactions, and hydrolysis. Examples of stabilization reactions include alkylation and esterification.

[0090] Cationically modified starch polymers may be incorporated into compositions in the form of hydrolyzed starch (e.g., acid, enzyme, or alkaline decomposition), oxidized starch (e.g., peroxide, peracid, hypochlorite, alkali, or any other oxidizing agent), physically / mechanically decomposed starch (e.g., by inputting thermomechanical energy into a processing apparatus), or a combination thereof.

[0091] The optimal form of starch is one that readily dissolves in water and forms a substantially clear aqueous solution (approximately 80% transmittance at 600 nm). The transmittance of the composition is measured by ultraviolet / visible (UV / VIS) absorbance spectroscopy, which measures the absorption or transmittance of the sample to UV / VIS light using a Gretag Macbeth Colorimeter Color i 5, according to the relevant instructions. A light wavelength of 600 nm has been shown to be suitable for characterizing the transparency of cosmetic compositions.

[0092] Cationic modified starches suitable for use as boosters are available from known starch suppliers. Nonionic modified starches are particularly suitable for use as boosters, and as is known in the art, they can be further derivatized into cationic modified starches. Other suitable modified starch starting materials can be quaternized, as is known in the art, to produce cationic modified starch polymers suitable for use as boosters.

[0093] Starch decomposition procedure: A starch slurry can be prepared by mixing granular starch in water. Raise the temperature to approximately 35°C. Next, add an aqueous potassium permanganate solution to a concentration of approximately 50 ppm based on the starch. Raise the pH to approximately 11.5 with sodium hydroxide, stirring the slurry thoroughly to prevent the starch from settling. Next, add a 30% solution of hydrogen peroxide diluted with water until the peroxide concentration based on the starch is approximately 1%. Subsequently, return the pH to approximately 11.5 by adding additional sodium hydroxide. This reaction takes approximately 1 to 20 hours to complete. Next, neutralize the mixture with dilute hydrochloric acid. The decomposed starch is recovered by filtration, then washed and dried.

[0131] As long as the polymer maintains its solubility or dispersibility in water, the hair care composition, or the coacervate phase of the hair care composition, and as long as the counterion is physically and chemically compatible with the essential components of the hair care composition, or otherwise does not excessively impair the performance, stability, or aesthetics of the product, the anionic counterion (X-) associated with the synthetic cationic polymer may be any known counterion. Non-limiting examples of such counterions include halides (e.g., chlorine, fluorine, bromine, iodine), sulfates, and methyl sulfates.

[0132] The cationic polymers described herein may help provide a substitute hydrophobic F layer to damaged hair, particularly chemically treated hair. This microscopically thin F layer helps retain moisture and prevent further damage while providing natural weather resistance. Chemical treatment damages the hair cuticle, causing the protective F layer to peel off. As the F layer peels off, the hair becomes more hydrophilic. It has been found that applying lyotropic liquid crystal to chemically treated hair makes it even more hydrophobic, resulting in an appearance and feel similar to untreated hair. While not bound by any particular theory, it is believed that lyotropic liquid crystal complexes form a hydrophobic layer or film, coating and protecting the hair fibers in a similar way to how the natural F layer protects hair. The hydrophobic layer restores the hair to a healthier state overall, similar to untreated hair. Lyotropic liquid crystals are formed by combining the synthetic cationic polymers described herein with the anionic cleansing surfactant components of the hair care composition described above. The charge density of the synthetic cationic polymers is relatively high. It should be noted that some synthetic polymers with relatively high cationic charge densities do not form lyotropic liquid crystals, mainly due to their unusually linear charge density. Such synthetic cationic polymers are described in International Publication No. 94 / 06403 (Reich et al.). The synthetic polymers described herein can be incorporated into stable hair care compositions that improve the conditioning performance of damaged hair.

These polymers also have molecular weights of about 1,000 to about 1,500,000, about 10,000 to about 1,500,000, and about 100,000 to about 1,500,000.

[0161] Such optional components must be physically and chemically compatible with the components of the composition and must not otherwise excessively impair the stability, aesthetics, or performance of the product. The CTFA Cosmetic Ingredient Handbook, Tenth Edition (published by the Cosmetic, Toiletry, and Fragrance Association, Inc. (Washington, DC)) (2004) (hereinafter referred to as "CTFA") describes a variety of non-limiting materials that may be added to the compositions herein.

[0162] 1. Conditioning agent The booster conditioning agent may be a silicone conditioning agent. The silicone conditioning agent may include volatile silicones, non-volatile silicones, or combinations thereof. The concentration of the silicone conditioning agent is typically in the range of about 0.01% to about 10% by weight, about 0.1% to about 8% by weight, about 0.1% to about 5% by weight, and / or about 0.2% to about 3% by weight of the composition. Non-limiting examples of suitable silicone conditioning agents and optional suspending agents for silicones are described in U.S. Reissue Patent No. 34,584, U.S. Patent No. 5,104,646, and U.S. Patent No. 5,106,609, which are incorporated herein by reference.

[0163] Silicone conditioning agents for use in the compositions of the present invention may have viscosities of about 20 to about 2,000,000 centistokes ("centistokes, csk"), about 1,000 to about 1,800,000 csk, about 10,000 to about 1,500,000 csk, and / or about 20,000 to about 1,500,000 csk when measured at 25°C.

[0164] Dispersed silicone conditioning agent particles typically have a volume-average particle size in the range of about 0.01 micrometers to about 60 micrometers. When smaller particles are applied to hair, the volume-average particle size is typically in the range of about 0.01 micrometers to about 4 micrometers, about 0.01 micrometers to about 2 micrometers, and about 0.01 micrometers to about 0.5 micrometers.

[0165] Further information on silicones, including sections on silicone fluids, rubbers, and resins, as well as the manufacture of silicones, can be found in the Encyclopedia of Polymer Science and Engineering, vol. 15, 2d ed., pp. 204-308, John Wiley & Sons, Inc. (1989), which is incorporated herein by reference.

[0166] Suitable silicone emulsions for use in the present invention include, but are not limited to, emulsions of insoluble polysiloxanes. These can be prepared by emulsion polymerization as described in U.S. Patent No. 6,316,541, or U.S. Patent No. 4,476,282, or U.S. Patent Application Publication No. 2007 / 0276087, or they can be emulsified after polymerization is complete by various emulsification methods as described in U.S. Patent No. 9,255,184(B2), or U.S. Patent No. 7,683,119, or Emulsions and Emulsion Stability, edited by Johan Sjoblom, CRC Press, 2005. Based on these references, a non-limiting list of suitable emulsifiers and emulsifier blends can be considered, based on the functionality of the silicone used, the emulsification method, and the desired emulsion particle size. Therefore, suitable insoluble polysiloxanes include polysiloxanes such as alpha,omegahydroxy-terminated polysiloxanes or alpha,omegaalkoxy-terminated polysiloxanes having an internal phase viscosity of about 5 csk to about 500,000 csk. For example, insoluble polysiloxanes may have an internal phase viscosity of less than 400,000 csk, less than 200,000 csk, or about 10,000 csk to about 180,000 csk. Insoluble polysiloxanes may have an average particle size in the range of about 10 nm to about 10 microns. The average particle size may be, for example, in the range of about 15 nm to about 5 micrometers, about 20 nm to about 1 micrometer, about 25 nm to about 550 nm, or about 1 to 10 micrometers. The concentration of dispersed silicone in the emulsion may be in the range of about 5 to 90 weight percent, or 20 to 85 weight percent, or 30 to 80 weight percent of the emulsion composition.

[0167] The average molecular weight of the insoluble polysiloxane, the internal phase viscosity of the insoluble polysiloxane, the viscosity of the silicone emulsion, and the particle size containing the insoluble polysiloxane are measured by methods widely used by those skilled in the art, such as the method disclosed in Smith, AL The Analytical Chemistry of Silicones, John Wiley & Sons, Inc.: New York, 1991. For example, the viscosity of the silicone emulsion can be measured at 30°C using a Brookfield viscometer with a spindle 6 at 2.5 rpm. The silicone emulsion may further contain additional emulsifiers, along with anionic surfactants.

[0168] Other types of silicones suitable for use in the compositions of the present invention include, but are not limited to, i) silicone fluids, including, silicone oils, which are fluid substances having a viscosity of less than about 1,000,000 csk when measured at 25°C; ii) aminosilicones containing at least one primary, secondary, or tertiary amine; iii) cationic silicones containing at least one quaternary ammonium functional group; iv) silicone gums, including materials having a viscosity of 1,000,000 csk or more when measured at 25°C; v) silicone resins, including highly crosslinked polymer siloxanes; vi) high refractive index silicones having a refractive index of at least 1.46; and vii) mixtures thereof.

[0169] The conditioning agent of the composition of the present invention may also contain at least one organic conditioning material, such as an oil or wax, either alone or in combination with other conditioning agents such as the silicones described above. The organic material may be a nonpolymer, oligomer, or polymer. It may be in the form of an oil or wax, and may be added directly to the formulation or in a pre-emulsified form. Some non-limiting examples of organic conditioning materials include, but are not limited to, i) hydrocarbon oils, ii) polyolefins, iii) aliphatic esters, iv) fluorinated conditioning compounds, v) aliphatic alcohols, vi) alkyl glucosides and alkyl glucoside derivatives, vii) quaternary ammonium compounds, viiii) polyethylene glycols and polypropylene glycols having a molecular weight of up to about 2,000,000, including those with CTFA names PEG-200, PEG-400, PEG-600, PEG-1000, PEG-2M, PEG-7M, PEG-14M, PEG-45M, and mixtures thereof.

[0170] 2. Emulsifier Various anionic and nonionic emulsifiers can be used in the hair care compositions of the present invention. Anionic and nonionic emulsifiers may be essentially monomers or polymers. Examples of monomers include, but are not limited to, alkyl ethoxylates, alkyl sulfates, soaps, and fatty acid esters, and their derivatives. Examples of polymers include, but are not limited to, polyacrylates, polyethylene glycols, and block copolymers, and their derivatives. Naturally occurring emulsifiers such as lanolin, lecithin, and lignin, and their derivatives, are also non-limiting examples of useful emulsifiers.

[0171] 3. Chelating agents Boosters may also contain chelating agents. Suitable chelating agents are those described in AE Martell & RM Smith, Critical Stability Constants, Vol. 1, Plenum Press, New York & London (1974) and AE Martell & RD Hancock, Metal Complexes in Aqueous Solution, Plenum Press, New York & London (1996), both of which are incorporated herein by reference. With respect to chelating agents, the term “salts and derivatives thereof” means salts and derivatives that contain the same functional structure (e.g., the same chemical backbone) as the referenced chelating agent and have similar or better chelating properties. This term includes alkali metals, alkaline earth metals, ammonium, substituted ammonium salts (i.e., monoethanolammonium, diethanolammonium, triethanolammonium) salts, esters of chelating agents having an acidic moiety, and mixtures thereof, in particular all sodium, potassium, or ammonium salts.

[0177] Product form The booster of the present invention can be present in typical hair care formulations. It may be in the form of a solution, dispersion, emulsion, foam, and other delivery mechanisms. The composition of the present invention may be in rinse-off hair care products such as shampoos, personal cleansing products, and treatment products, and in other forms that can be applied to hair.

[0178] delivery In the present invention, the booster composition can be delivered to the hands or hair / scalp by a pump bottle, airless pump, aerosol, dip tube pump, or squeeze bottle.

[0179] Applicator In this invention, the booster can be dispensed from the applicator and directly onto the scalp. By dispensing directly onto the scalp via a targeted delivery applicator, it becomes possible to directly apply the undiluted cleansing agent to areas where cleansing is particularly needed. This also minimizes the risk of the cleansing solution getting into the eyes.

[0180] The applicator is attached to, or can be attached to, a bottle containing a cleansing hair care composition. The applicator may consist of a base that holds one or more comb teeth or extends to comb teeth. The comb teeth may have openings that are located at the tip, the base, or at any point between the tip and the base. These openings allow the product to be dispensed directly from the bottle onto the hair and / or scalp.

[0181] Alternatively, the applicator may consist of brush-like bristles attached to or extending from the base. In this case, the product is dispensed from the base, and the bristles allow for distribution of the product through a combing or brushing motion.

[0182] The design and materials of the applicator and comb teeth can also be optimized to allow for scalp massage. In this case, it is beneficial for the shape of the comb teeth or bristles at the tip to be more rounded, similar to the rollerball applicators used for eye cream. The material may also be smoother and softer, for example, a metallic or metallic finish, or a "rubber-like material."

[0183] Measurement of adhesion of surfactant-soluble agents In vivo adhesion of surfactant-soluble agents to the scalp can be measured by treating the scalp with a surfactant-soluble agent containing a cleansing composition, rinsing it off, and then extracting the soluble agent with ethanol. The concentration of the agent in the ethanol extraction solvent is measured by HPLC. Quantification is performed relative to a standard curve. The concentration detected by HPLC is converted to grams to the collected amount by using the concentration multiplied by volume.

[0184] The percentage of the agent that adheres can be calculated using the following formula.

[0190] Example of adhesion efficiency calculation: The percentage of piroctone olamine adhering to the formulation in the example (%) = 1.92% Percentage of piroctone olamine adhering to the control formulation (%) = 1.02%

[0191]

number

[0192] In the present invention, the target adhesion of the scalp care active substance may be greater than about 0.5 μg / cm2 in order to produce the desired effect. The present invention may have adhesion of the scalp care active substance at about 0.3 to about 1.8 ug / cm2, about 0.5 to about 1.2 ug / cm2, or about 0.7 to about 1.0 ug / cm2.

[0193] Preparation of booster composition The booster is prepared by adding imaging components such as surfactants, anti-dandruff agents, fragrances, viscosity modifiers, dyes, pigments, and encapsulating agents, cationic polymers, and the remaining water while stirring thoroughly to form a homogeneous mixture. The mixture can be heated to 50-75°C to promote the dissolution of soluble substances and then cooled. To provide the shampoo composition of the present invention suitable for application to human hair and scalp, the product pH may be adjusted as needed, and the pH may vary between approximately pH 4-9, approximately pH 4-6, or approximately pH 4.5-5.5, based on the selection of specific cleansing surfactants and / or other components.

[0194] In the present invention, the booster may have a viscosity of about 3000 centipoise to about 8000 centipoise, about 3500 to about 6000 centipoise, or about 4000 to about 5000 centipoise. In the present invention, the viscosity of the booster may be about 4000 centipoise.

[0195] [Table 1-1]

[0196] [Table 1-2]

[0197] Hair care compositions A, B, C, and D correspond to the above-described examples A, B, C, and D.

[0198] When used as a conventional shampoo at conventional shampoo dosages, the following piroctone olamine (PO adhesion) is observed. Compositions B, C, and D are far more efficient at adhering to PO.

[0199] [Table 2]

[0200] Conventional hair care compositions currently on the market differ in two important aspects: the amount of surfactant used for cleansing and the amount of conditioning applied to the hair. In the present invention, by mixing the above-mentioned booster composition with a conventional shampoo, it is possible to provide consumers with scalp care effects without significantly affecting the desirable properties of the conventional shampoo, such as lathering, detangling, and hair smoothness. The dosage of the two formulations can vary depending on the scalp needs, in the ratio of the booster composition of the present invention to the conventional hair care composition, within the range of approximately 1 part booster composition to approximately 1 part conventional hair care composition, approximately 1 part booster composition to approximately 3 parts conventional hair care composition, or approximately 1 part booster composition to approximately 5 parts conventional hair care composition.

[0201] In this invention, a booster composition containing piroctone olamine is mixed with a conventional shampoo in a ratio of 2 parts of the booster composition of the present invention to 5 parts of the conventional shampoo, and the amounts of surfactant and conditioner are appropriately adjusted. In booster compositions A, B, C, and D of the present invention, the following amounts of piroctone olamine adhesion are observed.

[0202] [Table 3]

[0203] Hair care composition A is a representative example of a highly effective piroctone olamine-containing anti-dandruff shampoo currently on the market. When booster composition A of the present invention is mixed with conventional shampoo in a ratio of 2 parts to 5 parts, the adhesion efficiency is low, and it cannot be expected to alleviate dandruff symptoms in a timely manner. Conversely, when hair care composition D of the present invention is mixed with conventional shampoo in a ratio of 2 parts to 5 parts, the adhesion efficiency is much greater, comparable to that of using a standard anti-dandruff shampoo currently on the market alone, and it is expected to provide timely relief of dandruff symptoms while offering the desired cosmetic experience (lathering, cleansing, conditioning, fragrance, etc.) of using conventional shampoo alone.

[0204] Figure 1 shows two key properties of a typical cosmetic shampoo available today: cleansing power and conditioning power. When mixed with the present invention, after mixing the present invention with the cosmetic shampoo, the total anti-dandruff active substance concentration in the mixture decreases to about 30% of that of a typical effective anti-dandruff shampoo. However, it was found that piroctone olamine adhesion is maximized with the lower cleansing power cosmetic shampoo compared to the higher cleansing power shampoo. As the surfactant concentration of the cosmetic shampoo increases, the piroctone olamine adhesion efficiency decreases, as shown by the gradient in Figure 1.

[0205] Non-limiting examples The shampoo compositions shown in the following examples are prepared by conventional formulation and mixing methods. All quantities exemplified are listed as weight percentages of activity, and unless otherwise specified, diluents, preservatives, coloring solutions, imaging components, plant-based trace materials, etc. All percentages are based on weight unless otherwise indicated.

[0206] [Table 4]
