Description

[Technical Field]

[0001] The present invention relates to a detergent composition, and more specifically to a detergent composition that is filled into a foamer container for use. [Background technology]

[0002] Conventionally, detergent compositions capable of forming foam have been used. For such detergent compositions, the blending of various components has been investigated for the purpose of improving the quality of the foam and the feeling of use.

[0003] For example, Patent Document 1 describes a detergent composition containing an anionic surfactant, a nonionic surfactant, and a cationic polymer such as a dimethyldiallylammonium chloride polymer. This blend of ingredients allows the detergent composition in Patent Document 1 to form fine, elastic foam and is said to have an excellent feel during washing and after towel drying.

[0004] Furthermore, Patent Document 2 describes a detergent composition containing an anionic surfactant, a polyhydric alcohol, and a water-soluble polymer such as hydroxypropyl methylcellulose. Non-Patent Document 1 describes a detergent composition containing an anionic surfactant, glycerin, and galactoxyloglucan (tamarind gum). These detergent compositions are said to be able to form foam with good elasticity and thick foam with good foam retention, because the nonionic polymers hydroxypropyl methylcellulose and galactoxyloglucan are easily compatible with the surfactant.

[0005] The foam-forming detergent composition is preferably used by filling it into a foamer container that can discharge the detergent composition in a foam state (Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0007] [Non-Patent Document 1] Rei Iwata, "Application of nonionic polymer (tamarind gum) to skin care and hair care products", COSMETIC STAGE, Vol. 15, No. 1, 2020, pp. 39-44 Summary of the Invention [Problem to be solved by the invention]

[0008] However, the inventors have conducted studies and found that the cleansing compositions of the prior art are insufficient in any one of the following points: foam quality, dischargeability from a foamer container, and feel during washing or after towel drying.

[0009] In view of the above circumstances, an object of the present invention is to provide a cleanser composition that can form good foam, has excellent dischargeability from a foamer container, and provides a good feel during use during cleaning and after towel drying. [Means for solving the problem]

[0010] As a result of research, the inventors discovered that by incorporating a low-viscosity galactoxyloglucan, which has a viscosity of an aqueous solution below a predetermined value, and further by using a polyol in combination, the cleaning composition will have excellent performance as described above, and have completed the present invention.

[0011] That is, the cleaning composition according to the present invention comprises an anionic surfactant, a polyol, and a low-viscosity galactoxyloglucan whose 1.5% by mass aqueous solution has a viscosity of 150 mPa·s or less, The content of the low-viscosity galactoxyloglucan relative to the total mass of the detergent composition is 0.4 to 1.5% by mass.

[0012] According to this configuration, the product contains polyol and low-viscosity galactoxyloglucan, and the content of low-viscosity galactoxyloglucan is within the above range, so that good foam can be formed, and the product has excellent dischargeability from the foamer container and a pleasant feel when used during washing and after towel drying.

[0013] In the detergent composition according to the present invention, the low-viscosity galactoxyloglucan preferably has a viscosity of 1 to 100 mPa·s in a 1.5 mass % aqueous solution, and more preferably has a viscosity of 5 to 50 mPa·s.

[0014] According to this configuration, the low-viscosity galactoxyloglucan exhibits the above-mentioned viscosity, which makes it possible to form a better foam, and also provides better dischargeability from the foamer container and a better feel when used.

[0015] In addition, in the detergent composition according to the present invention, the content of the low-viscosity galactoxyloglucan relative to the total mass of the detergent composition is preferably 0.5 to 1.0% by mass.

[0016] According to this configuration, by ensuring that the content of low-viscosity galactoxyloglucan is within the above range, it is possible to form even better foam, and the dischargeability from the foamer container and the feel when used are even better.

[0017] The cleaning composition according to the present invention preferably contains, as the polyol, at least one selected from the group consisting of glycerin, diglycerin, 1,3-butylene glycol, propylene glycol, dipropylene glycol, pentylene glycol, isopentyldiol, polyethylene glycol, sorbitol, and glucose.

[0018] According to this configuration, by including the polyol as described above, it is possible to form a fine and elastic foam, and the feel after towel drying is excellent. [Effects of the Invention]

[0019] As described above, the present invention provides a cleanser composition that can form good foam, has excellent dischargeability from a foamer container, and provides a pleasant feel during cleaning and after towel drying. DETAILED DESCRIPTION OF THE INVENTION

[0020] Hereinafter, a cleaning agent composition according to one embodiment will be described with reference to an example of how the cleaning agent composition is filled into a foamer container.

[0021] The cleaning composition according to this embodiment contains an anionic surfactant, a polyol, a low-viscosity galactoxyloglucan, and water as a main component, and is liquid at temperatures between 5 and 25°C.

[0022] The former container is preferably a non-gas type former container, and examples thereof include a squeeze former container and a pump former container. These former containers typically include a container body that contains a liquid detergent composition, a discharge section having a discharge nozzle that discharges the foamed detergent composition, and a guide section having a guide nozzle that guides the detergent composition from the container body to the discharge section. The discharge nozzle and the guide nozzle are fluidly connected. The former container also includes a mixing section that is provided between the discharge section and the guide section and that mixes air into the detergent composition, and a mesh section that is provided downstream of the mixing section and that passes the aerated detergent composition through to form a foam. The mesh section is, for example, made of a porous plastic membrane. The non-gas type former container is configured to guide air and the detergent composition into the mixing section by the application of force from the user's fingers or the like (e.g., pressing the container body), while allowing the foamed detergent composition to be discharged from the discharge section.

[0023] Examples of the anionic surfactant include fatty acid salts, amino acid surfactants, sulfate ester salts, sulfonate salts, and ether carboxylic acid surfactants.

[0024] The fatty acid salt is preferably a salt of a saturated or unsaturated fatty acid having from 6 to 18 carbon atoms, more preferably a salt of a saturated or unsaturated fatty acid having from 8 to 18 carbon atoms. Furthermore, the fatty acid salt is preferably an alkali metal salt such as sodium or potassium, or a triethanolamine salt. More specifically, the fatty acid salt includes alkali metal salts or triethanolamine salts of lauric acid, myristic acid, palmitic acid, stearic acid, etc.

[0025] The amino acid-based surfactant is formed by condensing a carboxylic acid derived from a fatty acid with an amino group derived from an amino acid, and the carboxylic acid derived from the amino acid forms a salt. The fatty acid forming the amino acid-derived surfactant is preferably a saturated fatty acid or an unsaturated fatty acid having 8 to 18 carbon atoms. The amino acids that form the amino acid surfactants are preferably alanine, methylalanine, glutamic acid, and aspartic acid. As the base that forms a salt with the carboxylic acid derived from the amino acid, an alkali metal such as sodium or potassium, or triethanolamine is preferred.

[0026] Examples of the sulfate include alkyl sulfates (AS) such as lauryl sulfate and myristyl sulfate, and polyoxyethylene alkyl sulfates (AES) such as laureth sulfate. The alkyl group in the alkyl sulfate (AS) or polyoxyethylene alkyl sulfate (AES) preferably has 8 to 18 carbon atoms.

[0027] Examples of the sulfonates include α-olefin sulfonates (AOS) such as sodium tetradecene sulfonate.

[0028] Examples of the ether carboxylic acid surfactant include sodium polyoxyethylene lauryl ether acetate.

[0029] Among the above anionic surfactants, anionic surfactants that form carboxylates, such as the fatty acid salts and amino acid-derived surfactants, are preferred, as this allows the detergent composition to have excellent dischargeability from a foamer container at low temperatures (5°C).

[0030] The detergent composition preferably contains two or more, and more preferably three or more, anionic surfactants having different carbon numbers among those having from 8 to 18 carbon atoms. The detergent composition also preferably contains two or more, and more preferably three or more, anionic surfactants having different carbon numbers among those having from 12 to 18 carbon atoms. More specifically, the detergent composition preferably contains two or more saturated fatty acid salts having from 12 to 18 carbon atoms. For example, it is preferable to contain two or more, and more preferably three or more, of laurate, myristate, and palmitate. Alternatively, the detergent composition preferably contains two or more amino acid surfactants in which an amino acid is bonded to a saturated fatty acid having from 8 to 18 carbon atoms. For example, the detergent composition preferably contains two or more, and more preferably three or more, amino acid surfactants in which an amino acid is bonded to caprylate, caprate, laurate, myristate, palmitate, or stearate. This enables the detergent composition to form fine, elastic, and stable foam, which is easy to discharge from a foamer container and provides an excellent feel during washing and after towel drying.

[0031] The content of the anionic surfactant is preferably 1% by mass or more, more preferably 5% by mass or more, based on the total mass of the detergent composition, and is usually 10% by mass or less.

[0032] Examples of the polyol include sugars and alcohols having two or more hydroxyl groups.

[0033] The sugars are preferably sugars having 3 to 12 carbon atoms, and examples thereof include trioses (three-carbon sugars, such as glyceryl aldehyde and dihydroxyacetone), tetroses (four-carbon sugars, such as erythrose, threose, and erythrulose), pentoses (five-carbon sugars, such as ribose, lyxose, xylose, arabinose, abiose, ribulose, and xylulose), and hexoses (six-carbon sugars, such as glucose, mannose, galactose, and idose). Examples of sugars include aldose and ketose monosaccharides such as fructose (fruit sugar), sorbose, and heptose (seven-carbon sugars, such as sedoheptulose and coriose); disaccharides such as sucrose, maltose, trehalose, and cellobiose; trisaccharides such as maltotriose; oligosaccharides such as galactooligosaccharides; hydrolyzed products of water-soluble polymers such as dextrin (excluding the low-viscosity galactoxyloglucan); and sugar alcohols such as xylitol, sorbitol, mannitol, and erythritol. The sugars may be one type selected from these or a mixture of two or more types.

[0034] As the saccharide, a chain saccharide such as sorbitol is preferred over a cyclic saccharide such as glucose. When the detergent composition contains a chain saccharide, it becomes possible to form fine foam (particularly under low temperature conditions such as 5°C).

[0035] The alcohols include alcohols and alcohol derivatives. The alcohols are preferably alcohols having 3 to 10 carbon atoms, and examples thereof include dihydric alcohols (e.g., propylene glycol, propanediol, butylene glycol, pentanediol, isopentyldiol, etc.), trihydric alcohols (e.g., glycerin, trimethylolpropane, etc.), tetrahydric alcohols (e.g., pentaerythritol such as diglycerin and 1,2,6-hexanetriol), polyhydric alcohol polymers (e.g., dipropylene glycol, triethylene glycol, polyethylene glycol, polyglycerin, etc.), and polyhydric alcohol derivatives. The alcohols may be one type selected from these, or a mixture of two or more types.

[0036] Among the dihydric alcohols, those having 4 or less carbon atoms, such as propylene glycol and butylene glycol, are preferred over those having 5 or more carbon atoms, such as pentanediol and isopentyldiol. When the cleanser composition contains a dihydric alcohol having 4 or less carbon atoms, it is able to form elastic foam and provides an excellent feel after towel drying.

[0037] Among the polyhydric alcohol derivatives, those having 6 or less carbon atoms, such as diglycerin and dipropylene glycol, are preferred over those having a higher degree of polymerization, such as polyethylene glycol. By including a polyhydric alcohol derivative having 6 or less carbon atoms, the cleanser composition provides an excellent feel after towel drying.

[0038] Suitable examples of the polyhydric alcohol derivatives include alkylene oxide addition polymers of dihydric to tetrahydric alcohols. Examples of alkylene oxides to be addition polymerized include ethylene oxide (EO), propylene oxide (PO), and butylene oxide (BO). Specifically, examples of the alkylene oxide addition polymers of dihydric to tetrahydric alcohols include PPG-40 butyl (i.e., POP(40) butyl ether) (commercially available products include "Unilube MB-370" and the like), PPG-30 buteth-30 (i.e., POE(30)·POP(30) butyl ether) (commercially available products include "Unilube 50MB-72" and the like), and PPG-16 glyceryl ether (commercially available products include "Uniol TG-1000" and the like). Examples of such polyglycerides include PPG-24 glyceryl-24 (commercially available products include "Unilube 50TG-32"), PPG-25-polyethylene glycol-25 trimethylolpropane (commercially available products include "Unilube 43TT-2500"), PPG-14 diglyceryl ("Unilube DGP-950"), and PEG-5-PPG-65 pentaerythrityl ("Unilube 5TP-300KB") (all manufactured by NOF Corporation). Here, PPG stands for polypropylene glycol, POP for polyoxypropylene, POE for polyoxyethylene, and PEG for polyethylene glycol.

[0039] Sugar alcohols, a type of polyhydric alcohol, function as the sugars, but also as alcohols. Preferred examples of the sugar alcohols include pentahydric or hexahydric alcohols such as sorbitol and mannitol. Preferred examples of sugar alcohol derivatives include alkylene oxide addition polymers of sugar alcohols. Examples of alkylene oxides used in addition polymerization include EO, PO, and BO. Specific examples include POP sorbitol (commercially available products such as "Uniol HS-1600D" (manufactured by NOF Corporation)), POE(10) methyl glucoside (commercially available products such as "Glucam E-10" (manufactured by The Lubrizol Group, Inc.), and POP(20) methyl glucoside (commercially available products such as "Glucam P-20" (manufactured by The Lubrizol Group, Inc.), and the like).

[0040] The polyol is preferably glycerin, diglycerin, 1,3-butylene glycol, propylene glycol, dipropylene glycol, sorbitol, pentylene glycol, isopentyl diol, polyethylene glycol, or glucose, and more preferably glycerin, diglycerin, 1,3-butylene glycol, propylene glycol, dipropylene glycol, or sorbitol.

[0041] The content of the polyol is preferably 5% by mass or more, and more preferably 8% by mass or more, relative to the total mass of the detergent composition. This enables the detergent composition to form elastic foam and provides an excellent feel after towel drying. The content of the polyol is preferably 30% by mass or less, and more preferably 25% by mass or less. This enables the detergent composition to form fine foam and provide excellent dischargeability from a foamer container, even at low temperatures such as 5°C.

[0042] Galactoxyloglucan is a natural polysaccharide found in the cell walls (primary walls) of higher plants such as dicotyledons and monocotyledons. Galactoxyloglucan's constituent sugars are glucose, xylose, and galactose. The main chain of galactoxyloglucan is composed of glucose linked by β-1,4 bonds, and the side chains are composed of xylose bound to the glucose in the main chain and galactose bound to xylose. Galactoxyloglucan is obtained from tamarind, seeds of plants of the genus Hymena, soybeans, mung beans, kidney beans, rice, barley, apples, etc. Among these, tamarind seeds are preferred because they are easily available. Commercially available galactoxyloglucans include Glyloid (registered trademark) manufactured by DSP Gokyo Food & Chemical Co., Ltd.

[0043] In the present invention, it is important to use a low-viscosity galactoxyloglucan among galactoxyloglucans. Low-viscosity galactoxyloglucan means a 1.5% by mass aqueous solution of low-viscosity galactoxyloglucan (mass of low-viscosity galactoxyloglucan: mass of water = 1.5:98.5) that exhibits a viscosity of 150 mPa·s or less. The viscosity is measured using a Brookfield viscometer at 25°C and 30 rpm.

[0044] The viscosity of the low-viscosity galactoxyloglucan is preferably 90 mPa·s or less, and more preferably 50 mPa·s or less. This allows the detergent composition to be easily discharged from a foamer container (especially at 5°C) and provides a good feeling when used during cleaning. Furthermore, the viscosity of the low-viscosity galactoxyloglucan is particularly preferably 25 mPa·s or more and 35 mPa·s or less. This allows the detergent composition to form even more elastic and fine foam, providing excellent dischargeability and a good feeling when used.

[0045] The content of the low-viscosity galactoxyloglucan is preferably 0.4 to 1.5 mass %, more preferably 0.4 to 1.2 mass %, and even more preferably 0.4 to 1.0 mass %, relative to the total mass of the cleanser composition.

[0046] Low-viscosity galactoxyloglucan is prepared by degrading galactoxyloglucan such as Glyloid®, and the viscosity can be appropriately changed by adjusting the degree of decomposition.

[0047] For example, low viscosity galactoxyloglucan is prepared by chemical, physical or enzymatic degradation of galactoxyloglucan.

[0048] Examples of chemical decomposition include acid hydrolysis and alkaline hydrolysis. Acids used in acid hydrolysis include inorganic acids such as hydrochloric acid, sulfuric acid, phosphoric acid, and nitric acid, and organic acids such as citric acid, succinic acid, tartaric acid, acetic acid, and propionic acid. Among these, sulfuric acid and citric acid are preferred. Examples of bases used in alkaline hydrolysis include inorganic bases such as sodium hydroxide, potassium hydroxide, and calcium hydroxide.

[0049] Physical degradation includes heat treatment, high pressure homogenization, ultrasonic treatment, or mechanical shear treatment.

[0050] The enzyme used for enzymatic degradation is β-1,4-glucanase, ie, a plant tissue-degrading enzyme having so-called cellulase activity.

[0051] The low-viscosity galactoxyloglucan is preferably prepared by acid hydrolysis. More specifically, the low-viscosity galactoxyloglucan can be prepared as follows. First, galactoxyloglucan is dispersed in an aqueous alcohol solution, and then an acid is added and heated. Then, an alkali is added to neutralize the solution, and the precipitate is collected. After that, the precipitate is washed with an aqueous alcohol solution and dried to obtain low-viscosity galactoxyloglucan. The amount of galactoxyloglucan used in preparing low-viscosity galactoxyloglucan is 0.1 to 20% by mass of galactoxyloglucan relative to the total amount of the aqueous alcohol solution. The alcohol is preferably a lower alcohol such as methanol, ethanol, or isopropanol. The concentration of the aqueous alcohol solution is preferably 30 to 80% by mass. The amount of acid added is 0.1 to 20% by weight, preferably 1 to 10% by weight, relative to the aqueous alcohol solution. The pH of the solution is preferably less than 4. The reaction temperature is 20 to 150°C, preferably 40 to 121°C. The reaction time can be adjusted by measuring and monitoring the desired reaction time, for example, using a B-type viscometer (manufactured by Toki Sangyo Co., Ltd.), and is usually from a few seconds to 48 hours, preferably from 1 to 24 hours. The amount of alkali added is such that the solution becomes neutral (approximate pH: 6 to 8).

[0052] The water is preferably deionized water or distilled water. The content of water is usually 50% by mass or more, preferably 60% by mass or more, and more preferably 70% by mass or more, based on the total mass of the cleaning composition.

[0053] The viscosity of the detergent composition is preferably 20 mPa s or less, and more preferably 10 mPa s or less, at both temperatures of 5°C and 25°C, measured at 30 rpm using a Brookfield viscometer. This facilitates the operation of filling the detergent composition into a former container. This is preferable when the former container is to be used repeatedly, i.e., when it is a refillable former container. Furthermore, the detergent composition of the present embodiment has a viscosity within the above range, which provides an excellent feeling during use during cleaning.

[0054] The pH (25°C) of the detergent composition is usually 4 to 11.

[0055] The cleanser composition of the present embodiment can be used in various cleansers such as face washes, shampoos, hand soaps, body soaps, makeup removers, and toothpastes.

[0056] The cleaning composition of the present embodiment can form good foam and has excellent discharge properties even when filled into the non-gas type foamer container.

[0057] As described above, one embodiment has been shown as an example, but the cleaning composition according to the present invention is not limited to the configuration of the above embodiment. Furthermore, the cleaning composition according to the present invention is not limited by the above-described effects. The cleaning composition according to the present invention can be modified in various ways without departing from the gist of the present invention.

[0058] For example, the cleaning composition of the present invention may contain an amphoteric surfactant or a nonionic surfactant within a range that does not impair the effects of the present invention. Preferred amphoteric surfactants are aminoacetic acid betaine surfactants such as lauryl betaine and lauramidopropyl betaine. [Example]

[0059] The present invention will be further explained below with reference to examples, but the present invention is not limited to these examples.

[0060] [Preparation of low-viscosity galactoxyloglucan] A low-viscosity galactoxyloglucan exhibiting the viscosity shown in Table 1 was prepared by acid treatment of the galactoxyloglucan (DSP Glyloid, manufactured by Gokyo Food & Chemical Co., Ltd.) described in Non-Patent Document 1. Specifically, 272 g of 50% aqueous alcohol solution was placed in a pressure-resistant container, and 28 g of galactoxyloglucan was added and dispersed while stirring. Sulfuric acid was then added to adjust the pH of the solution to approximately 2. The solution was then heated to 110°C while stirring. After heating, aqueous sodium hydroxide solution was added to adjust the pH to approximately 7, and the mixture was filtered to obtain a precipitate. Next, 300 g of 50% aqueous alcohol solution was added to the precipitate, and the mixture was stirred and filtered to obtain a precipitate. 300 g of 50% aqueous alcohol solution was added to the precipitate again, and the mixture was stirred and filtered to obtain a precipitate, which was then dried at approximately 75°C to obtain a low-viscosity galactoxyloglucan. The heating time at 110°C was changed appropriately between 60 and 240 minutes to obtain low-viscosity galactoxyloglucans 1 to 7.

The viscosity of each aqueous solution was measured at 25°C and 30 rpm using a B-type viscometer (manufactured by Toki Sangyo Co., Ltd.). The results are shown in Table 1.

[0064] [Table 1]

[0065] [Evaluation of cleaning composition] Cleaning compositions were prepared according to the formulations shown in Tables 2 to 5, and evaluated for foam formation, dischargeability from a foamer container, and usability.

The results are shown in Tables 2 to 5.

[0066] [Evaluation of foam fineness] 50 mL of each detergent composition was filled into a pump former container (M1 50 mL, manufactured by Takeuchi Kikai Co., Ltd.) and stored until it reached 25° C. or 5° C.

[0067] [Evaluation of foam elasticity] 50 mL of each detergent composition was filled into a pump foamer container and stored until it reached 25° C. The pump foamer container was dispensed three times into the palm of one hand, and the foam was pressed with the other hand to evaluate the foam elasticity according to the following evaluation criteria. (Evaluation criteria) ◎: The foam has cushioning properties 〇: The foam has some cushioning properties ×: The foam has poor cushioning properties

[0068] [Foam viscosity measurement] 50 mL of each cleaning composition was filled into a pump former container and stored until it reached 25°C. The foam discharged from the pump former container was placed in a 100 mL beaker, and the foam viscosity (mPa s) was measured at 30 rpm using a B-type viscometer (manufactured by Toki Sangyo Co., Ltd.).

[0069] [Evaluation of foam stability] A bottle with a cap, 3 cm in diameter at the bottom and 6 cm in height, was filled to capacity with foam discharged from a pump foamer container. After leaving it to stand for 30 minutes, the total height of the foam layer and the water-releasing layer (A) and the height of the water-releasing layer (B) were measured. The height (C) of the foam layer after 30 minutes and the foam remaining rate were calculated using the following formula. Height of foam layer after 30 minutes (C) = Total height (A) - Height of water-release layer (B) Foam remaining rate after 30 minutes (%) = foam layer height after 30 minutes (C) ÷ foam layer height at 0 minutes (6 cm) × 100

[0070] [Evaluation of ejection properties] 50 mL of each detergent composition was filled into a pump former container and stored until the temperature reached 25°C or 5°C. Each temperature-adjusted detergent composition was discharged from the pump former container five times, and the dischargeability was evaluated according to the following evaluation criteria. (Evaluation criteria) ◎: Easy to dispense ○: Slight pressure felt when discharging ×: Pressure is felt when discharging, making it difficult to discharge

[0071] [Evaluation of feel during washing and after towel drying] 50 mL of each detergent composition was filled into a pump former container and stored until it reached 25°C. The pump former container was dispensed three times onto the palm of the hand, and the hand was then spread over the entire hand, washed with running water, and dried with a paper towel. The feel during washing and the feel after towel drying were evaluated according to the following evaluation criteria. (Evaluation criteria for feeling when using during washing) ◎: Refreshing and not sticky 〇: Slightly slimy, but refreshing ×: Strong slipperiness (Evaluation criteria for feel after towel drying) ◎: Moisturizing 〇: Slightly moist ×: No moist feeling and tightness

[0072] [Table 2]

[0073] [Table 3]

[0074] [Table 4]

[0075] [Table 5]

[0076] The evaluation results are shown in Tables 2 to 5. Examples 1 to 4 in Table 2 and Examples 5 to 13 in Table 3 show that blending 0.4% to 1.5% by mass of low-viscosity galactoxyloglucan results in excellent foam quality, dischargeability, and usability. On the other hand, Comparative Examples 1 to 11 show that blending galactoxyloglucan, xanthan gum, hydroxypropyl methylcellulose, or quaternary ammonium salt-type cellulose, blending 0.3% or less to 2.0% by mass of low-viscosity galactoxyloglucan, or no polysaccharide results in undesirable foam quality, dischargeability, and usability. Examples 2 and 14 to 22 in Table 4 show that various polyols provide excellent foam quality, dischargeability, and usability. Examples 2 and 23 to 32 in Table 5 show that various anionic surfactants provide excellent foam quality, dischargeability, and usability. Furthermore, in Examples 29 to 32, favorable effects were obtained even when an anionic surfactant was used in combination with an amphoteric surfactant or nonionic surfactant. Furthermore, a comparison of Example 28 with Comparative Example 12 reveals that the combined use of low-viscosity galactoxyloglucan and glycerin (polyol) is effective in forming good foam, achieving good dischargeability from the foamer container, and achieving a good feel when used. Furthermore, Examples 31 and 32 show that polyols other than glycerin, such as diglycerin, 1,3-butylene glycol, and sorbitol, also produced effects similar to those of Example 28, which contained glycerin.
