Description

[Technical field]

[0001] The present invention relates to daily care of the fur of pet animals such as dogs, cats, etc. More specifically, the object of the present invention is to keep pet animals clean by wiping their fur. [Background technology]

[0002] In recent years, more and more animals, such as dogs and cats, are kept indoors, and they have more opportunities to come into contact with their owners. As a result, there is an increased need to keep pets clean in order to prevent the unpleasant odors that are unique to pets, and the need to keep pets clean is on the rise.

[0003] Furthermore, keeping pets clean is important for preventing diseases and living a comfortable life. However, pet skin is delicate and repeated washing can induce dry skin. Since a detergent containing a strong detergent component degreases the skin, a mild detergent composition that does not dry the skin even after washing is desired. Conventionally, shampoo compositions with high cleaning power containing an anionic detergent mainly containing an amphoteric surfactant have been mainstream for pet detergents, but in recent years, attempts have been made to aim for a detergent composition that can be washed off with water or warm water, which contains a component that protects the skin, such as ceramide, which is gentle on the skin, after replacing the anionic detergent with a nonionic surfactant (Patent Document 1, Patent Document 2).

[0004] In recent years, the feel of fur after washing has become important. Therefore, a composition that improves the feel is desired, specifically a composition that makes the fur smooth and fluffy after drying, has an antistatic effect, and is easy to brush. The fur of animals, especially the fur of long-haired dogs and cats, is often thin and soft, and if not properly cared for on a daily basis, the fur is likely to become tangled or form hairballs. Furthermore, the fluffiness of the entire fur is easily reduced by oils such as sebum.

[0005] Problems with washing with shampoo compositions include the fact that dogs, cats, rabbits, guinea pigs, and other animals with light weights, which may be affected by individual differences, age, and other factors, tend to lose body temperature when they come into contact with water. Specifically, when the skin or fur gets wet with water, the heat of vaporization during drying can cause the body temperature to be rapidly lost, which can lead to poor physical condition. In addition, they may dislike being washed with water or hot water, which can cause stress. For example, many cats (domestic cats), which are said to have originally lived in the desert, dislike water, and are extremely averse to showers, threatening their owners or becoming violent and injuring themselves. For this reason, as guidance from veterinarians, etc., it is recommended that cats and rabbits, which frequently groom themselves on a daily basis, be washed less frequently, from once a month to once every six months, depending on the length of their fur.

[0006] In order to maintain the cleanliness of the coat through daily care, compositions have been proposed that can be used in a variety of ways, such as applying foam using a pump foamer or aerosol, spraying, or applying powder to the coat and then wiping it off with a towel, without using water, under the name of dry shampoo. The technology is thought to be based on dry shampoo for humans, but is insufficient as a composition for use on pet coats. For example, a detergent composition for non-gas foamers containing an anionic surfactant, ethyl alcohol, and a low molecular weight cationic surfactant has been disclosed as a technology for dry shampoo compositions for humans (Patent Document 3). However, because the stratum corneum of the skin of dogs and cats is very thin compared to that of humans, safety concerns remain unless the amount of low molecular weight cationic surfactant, which is known to be highly irritating, is reduced. In addition, a dry shampoo composition containing cationized hydroxypropyl cellulose with low irritation, alcohol with 2 to 4 carbon atoms, and an oily component has been disclosed. The amount of alcohol with 2 to 4 carbon atoms is at least 25%, which is high, so this composition is not suitable for dogs and cats that do not have an alcohol decomposition enzyme. In addition, the formulation of cationic cellulose, which has a high degree of accumulation (Patent Document 4), is known to easily cause stiff fur when used frequently, which may hinder the smooth feel of the product. While each of the commercially available products has its own merits, none are as safe as the ones that cleanse the coat and leave it smooth and fluffy.

[0007] In reality, it is extremely difficult to keep a pet's fur clean at all times. For example, there may be a concern about the smell of areas that cannot be groomed, the fur may become soiled with excrement and smell bad, white fur may turn yellow, or dirt may be brought in from outside. In these circumstances, there has been a need for the development of a composition that is suitable for keeping the fur clean using a simple method of use other than washing with water or hot water, and further a highly safe composition that gives the fur a fluffy finish and has deodorizing and anti-odor effects.

[0009] The problem to be solved by the present invention is to provide an aqueous hair wiping composition that has the effect of cleaning the hair of pet animals with a simple method of use other than washing with water or warm water, and further has high deodorizing and odor-preventing effects and the effect of making the hair smooth and fluffy. [Means for solving the problem]

[0010] In view of the above situation, the present inventors have conducted extensive research to obtain a composition for wiping hair that has an excellent effect of cleaning hair without using water or hot water and leaves a fluffy, soft finish, and have found that the desired effect can be obtained by directly applying or spraying an aqueous composition containing (A) a nonionic surfactant with an HLB of 14 or more, (B) an amino-modified silicone, (C) a cyclodextrin, and (D) an antibacterial agent onto the hair and then wiping the hair with a towel, etc., or by applying, spraying, or impregnating a towel, nonwoven fabric, tissue, etc. with the composition and wiping the hair.

[0011] That is, the present invention provides: [1] Next (A)~(E) (A) 0.1 to 5% by mass of a nonionic surfactant with an HLB value of 14 or higher (B) Amino-modified silicone (C) Cyclodextrin (D) Antibacterial agents Contains (E) The content of non-volatile liquid oil is 2% by mass or less. The aqueous hair wiping composition is [2] The aqueous composition for wiping hair according to claim 1, wherein the cyclodextrin (C) is α-cyclodextrin and / or hydroxypropyl-β-cyclodextrin. [3] The aqueous composition for wiping hair according to any one of claims 1 to 2, further comprising 0.1 to 1.0% by mass of an amphoteric surfactant (F), and is for use in a pump former. Effect of the Invention

[0012] The aqueous composition for wiping fur of the present invention can remove dirt from fur and clean it by a simple method of use other than washing with water or hot water, so that it can minimize the stress of pets who dislike water. It also has a high deodorizing and odor-preventing effect and an effect of making fur smooth and fluffy. BEST MODE FOR CARRYING OUT THEINVENTION

[0013] The present invention will be described in detail below. In this specification, percentages are expressed by mass unless otherwise specified. In this specification, when a numerical range is expressed using the symbols ~, the range includes both ends of the numerical range.

[0014] The aqueous composition for wiping hair of the present invention is mainly composed of water-soluble components. Specifically, the content of oily components that are insoluble in water is 2% or less. When an oily component is contained, it is solubilized or emulsified so that the oily components are present in a dispersed state in the aqueous phase.

[0015] The (A) nonionic surfactant having an HLB of 14 or more contained in the aqueous composition for wiping hair of the present invention is contained as a highly safe stain-removing component. Examples of such fatty acids include polyglycerin fatty acid esters, POE glycerin fatty acid esters, POE sorbitan fatty acid esters, POE sorbit fatty acid esters, POE castor oil / hydrogenated castor oil, POE alkyl ethers, POE / POP alkyl ethers, polyethylene glycol fatty acid esters, POE glyceryl isostearate, sucrose fatty acid esters, alkyl glucosides, etc. Among these, POE sorbitan fatty acid esters, polyglycerin fatty acid esters, and POE glycerin fatty acid esters are preferred in terms of forming a stable solubilized or emulsified composition when an oily component is further blended therewith.

[0016] Specific examples of POE sorbitan fatty acid esters include PEG-20 sorbitan isostearate, PEG-20 sorbitan cocoate, polysorbate 20, polysorbate 60, polysorbate 80, and the like.

[0017] Specific examples of polyglycerol fatty acid esters include polyglyceryl-6 monocaprylate, glyceryl-10 monocaprate, polyglyceryl-10 monolaurate, polyglyceryl-10 monomyristate, polyglyceryl-10 monopalmitate, polyglyceryl-10 monostearate, polyglyceryl-10 monooleate, and polyglyceryl-10 monoisostearate.

[0018] Specific examples of POE glycerin fatty acid esters include PEG-20 glyceryl isostearate, PEG-60 glyceryl isostearate, and PEG-7 (caprylic / capric acid) glycerides.

[0019] In the aqueous composition for wiping hair of the present invention, among the (A) nonionic surfactants having an HLB of 14 or more, one type may be used alone, or two or more types may be used in combination.

[0020] The blending amount of (A) the nonionic surfactant having an HLB of 14 or more is preferably 0.1 to 5.0 mass %, more preferably 0.5 to 3.0 mass %, and further preferably 1.0 to 2.0 mass %, of the total amount of the composition of the present invention.

[0021] HLB is a value that indicates the hydrophilic-hydrophobic balance usually used in the field of surfactants, and a commonly used calculation formula, such as the Kawakami formula, can be used. In the present invention, the following Kawakami formula is adopted.

number

[0022] The amino-modified silicone (B) contained in the aqueous hair wiping composition of the present invention can be any silicone that is generally used for external application to the skin. The component (B) of the present invention gives the hair a fluffy finish and a smooth feel, and has the effect of making the hair tips neat and tidy. In addition, it has an antistatic effect.

[0023] The amino-modified silicone (B) used in the present invention is not particularly limited as long as it is generally used for external application to the skin, and examples thereof include aminopropyl dimethicone, biscetearyl amodimethicone, aminoethyl aminopropyl methyl siloxane-dimethyl siloxane copolymer, (aminoethyl aminopropyl methicone / dimethicone) copolymer, etc.

[0024] Among (B) amino-modified silicones, from the viewpoint of achieving both less stickiness of hair after washing and manageability of hair ends, preferred are aminopropyl dimethicone and aminoethyl aminopropyl methyl siloxane-dimethyl siloxane copolymer. Furthermore, aminoethyl aminopropyl siloxane-dimethyl siloxane copolymer emulsions that are pre-emulsified are preferred because they are easy to homogenize and can be manufactured simply.

[0025] (B) Commercially available amino-modified silicones include KF-8005 (Shin-Etsu Chemical Co., Ltd.), XF42-B1989 (Momentive Performance Materials), and SM 8904 COSMETIC EMULSION (Dow Corning Toray Co., Ltd.).

[0026] In the aqueous composition for wiping hair of the present invention, the above-mentioned (B) amino-modified silicones may be used alone or in combination of two or more.

[0027] The blending amount of (B) amino-modified silicone used in the present invention is preferably 0.01 to 0.8 mass%, more preferably 0.04 to 0.4 mass%, and even more preferably 0.03 to 0.2 mass%. If the blending amount of (B) amino-modified silicone is within this range, the fluffy feeling of the coat is improved, the smooth feeling is obtained, and the effect of making the hair tips manageable is remarkable. Furthermore, a good antistatic effect is obtained.

[0028] The cyclodextrin (C) contained in the aqueous hair wiping composition of the present invention may be α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin and / or their derivatives, or a mixture thereof. Examples of cyclodextrin derivatives include molecules in which a portion of the hydroxyl groups is replaced with an OR group. Examples of R include hydrocarbons such as methyl and ethyl groups, and hydroxyalkyl groups such as hydroxyethyl and hydroxypropyl groups. Specific examples of (C) cyclodextrin include α-cyclodextrin (solubility: 14.5 g / 100 ml: water at 25° C.), β-cyclodextrin (solubility: 1.85 g / 100 ml: water at 25° C.), γ-cyclodextrin (solubility: 23.2 g / 100 ml: water at 25° C.), hydroxypropyl-β-cyclodextrin (solubility: >200 g / 100 ml: water at 25° C.), methylated-β-cyclodextrin (solubility: >200 g / 100 ml: water at 25° C.), etc. Furthermore, in the composition of the present invention, when the temperature drops in winter or when the composition interacts with other components such as cationic components, the solubility of the cyclodextrin may decrease, causing precipitation. Therefore, it is preferable to use α-cyclodextrin or hydroxypropyl-β-cyclodextrin, which are easily available and have good water solubility.

[0029] Cyclodextrin molecules have a cyclic structure, and the inside is hydrophobic. Therefore, cyclodextrin can form an inclusion complex in which an organic molecule or a part of an organic molecule is adsorbed inside, and can deodorize, for example, malodorous substances, particularly low-polarity malodorous substances generated by the metabolism of microorganisms, by inclusion. In particular, it is well known that α-cyclodextrin can capture and deodorize short-chain fatty acids such as isovaleric acid and methyl mercaptan. Cyclodextrin is generally known to have little effectiveness against low-molecular-weight polar substances such as ammonia. However, the combination of the present invention as a pet cleaning composition surprisingly showed a high deodorizing effect immediately after use. Furthermore, the deodorizing effect lasted for several days, which is suitable for a pet cleaning composition that is rarely washed.

[0030] (C) Commercially available cyclodextrin products include trade names such as CAVAMAX W6, W7, W8, CAVASOL W7 HP, and W7 M (manufactured by WACKER CHEMICALS).

[0031] In the aqueous hair wiping composition of the present invention, the above (C) cyclodextrin may be used alone or in combination of two or more. The combination of two or more is more preferable because it can encapsulate various malodorous components.

[0032] The amount of cyclodextrin (C) contained in the aqueous hair wiping composition of the present invention is preferably 0.1 to 20.0% by mass, more preferably 0.6 to 15.0% by mass, and even more preferably 1.0 to 10.0% by mass. Within this range, the deodorizing effect of malodorous substances is very good. When it is 10.0% by mass or less, the storage stability at low temperatures and usability are very good.

[0033] The aqueous hair wiping composition of the present invention contains (D) an antibacterial agent. The antibacterial agent used in the present invention refers to a component that has an effect of inhibiting the growth of bacteria or a bactericidal effect against various bacteria (fungi, gram-positive bacteria, gram-negative bacteria, etc.). It is preferably a component that can be used as the main ingredient of a quasi-drug. Specifically, the antibacterial agent can be isopropylmethylphenol, salicylic acid and its salts, benzoic acid and its salts, benzalkonium chloride, benzethonium chloride, cetylpyridinium chloride, etc. In the present invention, from the viewpoint of high durability of the antibacterial effect and bactericidal effect, it is preferable to use isopropylmethylphenol or cetylpyridinium chloride, and more preferably isopropylmethylphenol, in the aqueous hair wiping composition of the present invention.

[0034] In the aqueous composition for wiping hair of the present invention, the above-mentioned (D) antibacterial agent may be used alone in a single type, but a combination of two or more types is more preferable since it provides antibacterial properties against a wide range of bacterial species.

[0035] The amount of the antibacterial agent (D) in the aqueous hair wiping composition of the present invention can be appropriately set depending on the application, the degree of the desired effect, and the like. As an example, the amount of the component (D) is preferably 0.01 to 1 mass%, more preferably 0.02 to 0.5 mass%, based on the entire composition. It is even more preferably 0.05 to 0.2 mass%. According to the present invention, even a small amount of the antibacterial agent (D) can exhibit a sufficient deodorizing effect due to the sustained antibacterial effect. Although the principle is unclear, it is thought that this is because the hair remaining property of the component (D) is improved in the combination of the present invention.

[0036] The ratio of the cyclodextrin (C) and the antibacterial agent (D) of the present invention is not particularly limited, but it is preferable to mix them at a ratio of (C) / (D) = 10 to 500. Within this range, although the principle is unclear, the cyclodextrin (C) can stabilize the antibacterial agent (D), and the deodorizing effect is enhanced due to a synergistic effect, so that a clean state is maintained.

[0037] The aqueous hair wiping composition of the present invention may contain 0% to 2% by mass of (E) non-volatile liquid oil. The (E) non-volatile liquid oil in the aqueous hair wiping composition of the present invention is a non-volatile oil that is liquid at 20°C, and liquid at 20°C is one that has fluidity at 20°C. In addition, non-volatile means that 1g of oil is spread on a glass petri dish with a diameter of 48 mm, and the mass loss rate after leaving it at 25°C and normal pressure for 24 hours is 1% or less. Furthermore, the solubility in water at 25°C is 0.1% or less. (E) The non-volatile liquid oil is not particularly limited as long as it is generally used for external application to the skin. Examples of oils that can be used include hydrocarbon oils, vegetable oils, animal oils, ester oils, higher alcohol oils, and silicone oils.

[0038] Specifically, animal and vegetable oils such as avocado oil, macadamia nut oil, olive oil, rapeseed oil, sesame oil, wheat germ oil, linseed oil, cottonseed oil, soybean oil, palm oil, coconut oil, castor oil, jojoba oil, sunflower oil, camellia oil, and corn oil; hydrocarbon oils such as liquid paraffin, liquid isoparaffin, mineral oil, hydrogenated polyisobutene, hydrogenated polydecene, squalane, and squalene; isopropyl myristate, octyldodecyl myristate, isopropyl isostearate, isononyl isononanoate, butyl stearate, and isotridecyl isononanoate. Examples of suitable oils include ester oils such as ethylhexyl palmitate, cetyl ethylhexanoate, octyl methoxycinnamate, propylene glycol dicaprylate, propanediol diisostearate, glyceryl tri(caprylate / caprate), triethylhexanoin, and trimethylolpropane triisostearate; branched higher alcohols such as isostearyl alcohol and octyldodecanol; and silicone oils such as diphenyl dimethicone, dimethylpolysiloxane, and methylphenylpolysiloxane.

[0039] In the aqueous composition for wiping hair of the present invention, when the non-volatile liquid oil (E) is blended, one type may be used alone, or two or more types may be used in combination.

[0040] (E) By adding a non-volatile liquid oil, the smoothness of the fur after drying can be further improved. However, if the amount added exceeds 2%, the fur becomes too clumpy and loses its fluffy feel, which is not desirable as a finish.

[0041] When a nonwoven fabric impregnated with the composition of the present invention is packed in multiple sheets to produce a pet cleaning sheet, the nonwoven fabric to be used is not particularly limited, and nonwoven fabrics made of various synthetic fibers (polyester, etc.), regenerated fibers (rayon, etc.), and natural fibers (cotton, etc.) can be used, and may be long-fiber or short-fiber nonwoven fabrics. In particular, cotton spunlace is preferred because it is easy to impregnate with the composition and is safe from a health perspective. Cotton spunlace is a nonwoven fabric obtained by hydroentangling cotton fibers, is readily available commercially, and has a basis weight of 40 g / m. 2 ~80g / m 2 The above is particularly preferably used in the present invention.

[0042] The thickness of the nonwoven fabric is not particularly limited, but in order to avoid insufficient strength and easy tearing, to ensure a good fit, and to prevent leaving any areas unwiped, a thickness of 0.05 to 5 mm, or even 0.1 to 3 mm is preferable. Similarly, the size of the nonwoven fabric varies depending on the target animal, but taking into consideration ease of handling and wiping efficiency, a thickness of 100 to 2000 cm is preferable. 2 , and even 400-1000cm 2 The nonwoven fabric may be embossed as necessary for the purpose of increasing the dirt removal performance.

[0043] The amount of the composition impregnated into the nonwoven fabric depends on the type of nonwoven fabric, but if it is too small, the wiping effect is not achieved, while if it is too much, it drips down, which is unsightly and wasteful. Therefore, the amount may be appropriately determined taking these points into consideration, and is preferably 1 to 5 times the mass of the nonwoven fabric, and more preferably 2 to 4 times.

[0044] When the present invention is used as a cleaning sheet, it is possible to remove pet hair, skin dirt, and body odor simply by wiping, and to easily keep the pet clean. It can be made small and easily portable for when going out for a walk or traveling with a pet, or it can be made into a product like a box of tissues with many sheets so that it can be used constantly in a fixed place in the house, or a product sealed with a film to prevent evaporation.

[0045] By further blending an amphoteric surfactant (F) into the aqueous hair wiping composition of the present invention, the foaming properties when used with a pump foamer and the effect of removing dirt from hair can be further improved.

[0046] Examples of the (F) amphoteric surfactant include imidazoline-based amphoteric surfactants and betaine-based amphoteric surfactants. Betaine-based surfactants are particularly preferred, and specific examples thereof include alkyl betaine-type amphoteric surfactants such as lauryl dimethyl amino acetate betaine, coconut oil alkyl dimethyl amino acetate betaine, and stearyl dimethyl amino acetate betaine, and alkyl amido betaine-type amphoteric surfactants such as coconut oil fatty acid amidopropyl betaine and lauric acid amidopropyl betaine. Among these, lauric acid amidopropyl betaine and coconut oil fatty acid amidopropyl betaine are preferred from the viewpoint of good foaming when used in a pump foamer container.

[0047] In the aqueous composition for wiping hair of the present invention, the above-mentioned (F) amphoteric surfactants may be used alone or in combination of two or more kinds.

[0048] The amount of the amphoteric surfactant (F) blended is preferably 0.1 to 1 mass% based on the mass of the composition. More preferably, it is 0.2 to 0.7 mass%. Even more preferably, it is 0.3 to 0.5 mass%. Within this range, the removal of dirt from fur is improved, and in addition, when used with a pump former, a firm and fine lather can be obtained, making the composition suitable for a pump former.

[0049] The aqueous hair wiping composition of the present invention may contain any of a variety of ingredients as necessary, provided that the effects of the present invention are not impaired. For example, the aqueous hair wiping composition of the present invention may contain solid or semi-solid oils, volatile liquid oils, surfactants other than component (A), monohydric alcohols, aqueous gelling agents and thickeners, moisturizers, preservatives, etc.

[0050] Examples of solid oils, semi-solid oils, and volatile liquid oils include natural animal and vegetable oils, hydrocarbon oils, silicone oils, higher alcohols, higher fatty acids, and ester oils.

These may be used alone or in combination of two or more kinds, as required.

[0051] The other surfactants are not particularly limited as long as they are generally used for external application to the skin, and any surfactant other than (A) nonionic surfactants with HLB of 14 or more and (G) amphoteric surfactants can be used. Examples of surfactants include (A) nonionic surfactants with HLB of less than 14, anionic surfactants, cationic surfactants, etc., and these can be used alone or in combination of two or more kinds as necessary.

[0052] The monohydric alcohol is not particularly limited as long as it is generally used for external application to the skin, and any of them can be used.

[0056] The aqueous hair wiping composition of the present invention may be in the form of a liquid or emulsion, and may be applied or sprayed directly onto the hair and then wiped with a towel or the like. Alternatively, the composition may be applied, sprayed, or impregnated onto a towel, nonwoven fabric, tissue, or the like, and then used to wipe the hair. As a preferred example, a plurality of nonwoven fabrics that have been impregnated with the composition may be packed together to form a wiping sheet. The composition may also be used as a spray using compressed air or as a foam using a pump former. The composition may also be used as an aerosol product, such as a spray or mousse, using a propellant. Furthermore, the same composition can be used to make a composition for wiping pet equipment.

[0057] The aqueous hair wiping composition of the present invention can be used by filling it into a non-gas type foam discharge container having a porous membrane, which is a pump foam container for a conventionally known detergent. A non-gas type pump foam container is a container in which a certain amount of liquid is mixed with a certain amount of air and discharged in a foam state from the container when used. The pump foam container may be any known type. Specifically, a squeeze foamer used by pressing the body of a soft container, a pump foamer used by pressing the head of a cap equipped with a pump mechanism, etc. are mentioned. When used, the liquid in the container is pressurized and the mixture mixed with air is passed through a porous membrane (one or more sheets), and the mixture is discharged in a foam state from the discharge port of the container. Examples of the porous membrane of the pump foam container include a sponge, a sintered body, and a net, but a net is preferable from the viewpoint of usability. A mesh size of about 30 to 400 mesh is preferably used. EXAMPLES

[0058] The present technology will be described in more detail below with reference to examples and comparative examples, but the present invention is not limited thereto.

[0059] Examples 1 to 6 and Comparative Examples 1 to 8 The compositions shown in Tables 1 and 2 (hereinafter referred to as "samples") are produced by the following production method. [Manufacturing method] 1: When ingredient (E) is not included (i) Dissolve each component in purified water. 2: When ingredient (E) is included (i) The oil component, (A) or (A') and 1,3-butylene glycol are premixed. (ii) Add the remaining ingredients to purified water and dissolve, then add (i). (iii) Process using a tabletop homogenizer (3000 rpm x 1 minute per 500 g).

[0060] [Easy to remove dirt] A colored oily model soil composition was prepared by mixing the following formulations: Oil-based dye (Sudan III, manufactured by Wako Pure Chemical Industries, Ltd.) 1 part Oleic acid 1 part 9 parts Vaseline Polyethylene glycol 1500 89 parts 0.1 g of the model soiling composition is applied in a circle having a diameter of 2 cm on an acrylic plate 1 (10 cm x 10 cm x 0.5 cm). In addition, a nonwoven fabric (100% cotton, 40 g / m2) is applied to an acrylic plate 2 (3 cm x 3 cm x 0.5 cm). 2 A cotton spunlace nonwoven fabric (Miracle Cotton manufactured by Marusan Sangyo Co., Ltd.) is wound twice, and 0.3 g of the sample is sprayed onto this nonwoven fabric. Next, the acrylic plate 2 is placed on the acrylic plate 1 on which the model soil composition is placed, with the side sprayed with the sample facing down. A weight of 300 g is placed on the acrylic plate 2. Next, the acrylic plate 2 is moved horizontally at a speed of 500 mm / min to wipe off the model soil composition. After repeating this wiping operation three times, the remaining soil is washed with 15 ml of ethanol. The absorbance of this washing solution at 500 nm is measured. The amount of the remaining soil is quantified using the measured value and a calibration curve prepared in advance. The model soil composition is wiped off at 90% or more, with an O, 85% to less than 90%, with an X.

[0061] [Sensory evaluation] The samples were evaluated one day after preparation according to the following usage method. Three expert panelists (trimmers) treated 15 long-haired cats (weight 4-5 kg, age 1-5 years) in groups of three, evaluating the ease of drying and fluffiness of the coat after drying. Treatments for evaluation were always performed at least two weeks apart. Evaluation was based on a five-point scale according to the following criteria, and the average score was used to evaluate according to the following judging criteria. [Evaluation Criteria] (Evaluation result): (Score) Good: 5 points Fairly good: 4 points Average: 3 points Slightly poor: 2 points Defective: 1 point [Judgment criteria] (Average score): (Judgment) 4.0 or higher: ◎ 3.0 or more and less than 4.0: 〇 2.0 or more and less than 3.0: △ Less than 2.0: ×

[0062] [Smoothness of fur after drying] From April to May, hair from long-haired dogs (English setter, two Shetland sheepdogs, and a border collie; all double-coated breeds) kept outside was collected by brushing during the spring shedding season, and then cut into 10 cm bundles of 1g each. The smoothness of the hair bundle after drying was measured using a friction tester (Kato Tech Co., Ltd., KESSE-STP type). The hair bundle was attached to the tester, and the friction coefficient (MIU value / average friction coefficient) was measured when it was rubbed with a 10 mm square piano wire sensor contact. The measurement conditions were vertical load: 25 g, speed: 0.5 mm / s. The coefficient of friction (μ0) before treatment was measured using a bundle of fallen hair that had been left to stand for three days in a constant temperature and humidity room at room temperature of 20°C and humidity of 40%, and then 0.1 g of each sample was applied and left to stand again for three days in a constant temperature and humidity room at room temperature of 20°C and humidity of 40%. After that, the coefficient of friction (μa) was measured in the same way.

[0063] [Odor evaluation] In the present invention, deodorization refers to the effect of eliminating a foul odor when it has already occurred, and deodorization refers to the effect of preventing a foul odor from occurring or becoming stronger over time. [Deodorizing effect / Odor immediately after use] Hair samples were prepared by cutting off approximately 1cm from the tip of the hair from the tails of long-haired dogs kept outside (one English setter, two Shetland sheepdogs, one Border collie; all double-coated dogs) and placing them in a beaker. The hair samples were then mixed well to make a homogenous mixture and used as hair samples. 2g of each hair sample was placed in a 500ml beaker and the sample was sprayed from a spray bottle (approximately 0.3g per push) to confirm the deodorizing effect. [Deodorizing effect / odor after 3 days] The samples used in the "Deodorizing effect / Odor immediately after use" section above were sealed in food wrap and left in a 37°C incubator for 72 hours, after which the odor was confirmed. Three expert panelists evaluated the product on a 5-point scale according to the following criteria, and the average score was used to judge the product according to the following criteria. [Evaluation Criteria] (Evaluation result): (Score) No smell: 5 points Almost no odor: 4 points Slightly smelly: 3 points Smell: 2 points Strong odor: 1 point [Judgment criteria] (Average score): (Judgment) 4.0 or higher: ◎ 3.0 or more and less than 4.0: 〇 2.0 or more and less than 3.0: △ Less than 2.0: ×

[0064] [How to use] Table 1 (Spray) 1: Fold a pile cotton towel (size: 20cm x 60cm) into four lengthwise (size of each side: 20cm x approximately 15cm) and use all 8 sides. 2: Fill the spray container with the sample and spray 5 times (amount used: approximately 1.5g) onto one folded side. 3: Wipe the fur, focusing on areas of concern. 4: For the remaining side, fill the spray container with the sample and spray 5 times (amount used: approximately 1.5 g). 5: Wipe the coat thoroughly. 6: Use the remaining two sides to towel dry. (For long-haired breeds, repeat steps 2-5 twice, then towel dry the remaining 4 sides.)

[0065] Table 2 (Pump former) 1: Fold a pile cotton towel (size: 20cm x 60cm) into four lengthwise (size of each side: 20cm x approximately 15cm) and use all 8 sides. 2: Fill the pump former container with the sample for one folded surface and push twice (discharge amount: approx. 2 g). 3: Wipe the fur, focusing on areas of concern. 4: For the remaining side, fill the pump former container with the sample and push twice (amount used: approximately 2 g). 5: Wipe the coat thoroughly. 6: Towel dry using both sides. (For long-haired breeds, repeat steps 2-5 twice, then towel dry the remaining 4 sides.) [Evaluation of foaming when produced using a pump former] The height of the foam is evaluated immediately after it is discharged once from the pump foamer onto an acrylic plate wiped with a 50% aqueous solution of ethanol. [Judgment criteria] Bubble height 2.0cm or more: ◎ 1.0cm to less than 2.0cm: 〇 0.5cm to less than 1.0cm: △ Less than 0.5cm: ×

[0067] For Examples 1 to 5, the effect of cleaning the fur and the effect of leaving a fluffy finish, which are the object of the present application, were felt, and the compositions were favorably evaluated as compositions for wiping pet fur. In Comparative Example 1, the fur was poorly cleaned, and therefore it was not suitable as a cleaning spray that puts less strain on pets. In Comparative Example 2, the amount of hydrophilic nonionic surfactants blended as a cleaning agent was too high, so it was difficult to dry. Furthermore, it was evaluated that the fur was not fluffy even after drying. In Comparative Example 3, the PEG-50 hydrogenated castor oil with HLB 13.5 had little cleaning effect, and it was difficult to remove dirt, and it was difficult to dry, and even after towel drying, the fur was sticky and did not feel smooth. In Comparative Example 4, since the aminoethylaminopropylsiloxane-dimethylsiloxane copolymer (B), which is an amino-modified silicone, was not blended, the fluffy feeling after drying was not felt, and the smoothness was not felt. In Comparative Example 5, stearyl trimethylammonium chloride, a treatment agent commonly used in human hair conditioners, was blended in approximately the same amount as in Example 1. The fluffy feeling of the fur after drying and the smoothness of the fur after drying were not sufficiently effective. In Comparative Example 6, similar to Comparative Example 5, polyquaternium-10 (cationized cellulose), a commonly used treatment agent, was blended in the same amount as in Example 1. The fluffiness of the fur after drying was improved, but the smoothness of the fur after drying was poorly evaluated due to a particular stiffness felt. In Comparative Example 7, since (C) cyclodextrin was not blended, the deodorizing effect immediately after use was hardly felt, and the (D) antibacterial agent alone was not effective in preventing odors after three days, and there was no deodorizing effect. In Comparative Example 8, the deodorizing effect of (C) cyclodextrin was felt immediately after use, but the odor after three days was poorly evaluated, probably because (D) antibacterial agent was not blended, and the deodorizing effect was low. From the evaluations of Example 1 and Comparative Examples 6 and 7, a synergistic effect was seen in the deodorizing effect (effect of suppressing bad odors for a long time) that was not seen with either (C) cyclodextrin or (D) antibacterial agent alone. In Comparative Example 9, the fur was evaluated as being smooth, but not fluffy because the amount of oil was too high. After using the compositions of the above examples and comparative examples, when brushing the fur after it had completely dried, static electricity was generated only in Comparative Example 6.

[0069] For Examples 1, 6, and 7, good evaluation results were obtained for "dirt removal," "ease of drying," "fluffiness of fur after drying," "smoothness of fur after drying," "deodorizing effect / smell immediately after use," and "deodorizing effect / smell after 3 days." Furthermore, for Examples 5 and 6, it was an optimal composition for a pump former that formed a firm, bulky foam. For Example 1, a slightly low-bulk foam was formed, and the foam retention time was shorter than for Examples 5 and 6, but the usability was good. For Comparative Example 1, there was almost no foaming. For Comparative Example 10, the concentration of the surfactant was high, so the foaming was good, but it did not dry and remained sticky for a long time, and the evaluation was that the "fluffiness of fur after drying" and "smoothness of fur after drying" were not felt.

[0070] Example 7 100% cotton, 40g / m 2 A cotton spunlace nonwoven fabric (Miracle Cotton, manufactured by Marusan Sangyo Co., Ltd.) was cut to 30 cm x 30 cm and impregnated with 8 g of the composition of Example 1 of the present invention to obtain a wet sheet for wiping fur. When this wet sheet was used to wipe the fur of an indoor Shiba Inu (weight 5 kg), it was possible to easily remove dirt and body odor. After drying, the fur was left smooth and fluffy.
