Mode for Carrying Out the Invention The mechanism by which the detergent composition of the present invention has excellent cleaning properties, rinsing properties and finishing properties for textile products and further imparts antibacterial properties to the textile products is not clear, but is presumed to be as follows.
It is presumed that the cleaning ability of the detergent composition of the present invention against sebum stains is improved by using a nonionic surfactant as component (a1), an anionic surfactant as component (a2), and an alkaline agent as component (b1) in combination.
It is also presumed that the cleaning power of the detergent composition of the present invention against muddy soils is improved by the combined use of component (a2) and the anionic polymer (E).
It is also believed that the cleaning composition of the present invention achieves both rinsability and finish by containing a specific component (A) and further by controlling the ratio of the water-soluble inorganic salt of component (B) to the water-insoluble inorganic salt of component (C) within a specific range. Note that the finish in the present invention refers to reducing the amount of undissolved part of the cleaning composition and reducing streaks on the washed object.
Furthermore, it is presumed that the combination of components (A) to (E) in the cleaning composition of the present invention provides excellent cleaning properties, rinsing properties and finishing properties for textile products without impairing the antibacterial activity of component (D).
The action mechanism of the cleaning composition of the present invention is not limited to the above-mentioned mechanism.

In other words, the detergent article of the present invention may be a detergent article consisting of the detergent composition of the present invention and a water-soluble film, the detergent composition is packaged in the water-soluble film, the major axis diameter of the maximum projected area of the detergent article is 30 mm or more and 200 mm or less, the aspect ratio between the major axis diameter and the minor axis diameter perpendicular to the major axis diameter (major axis diameter/minor axis diameter) is 5 or more, and the burst strength is 300 N or more.

The aspect ratio (major axis diameter/minor axis diameter) of the major axis diameter of the maximum projected area of the detergent article of the present invention to the minor axis diameter perpendicular to the major axis diameter is preferably 5 or more, more preferably 6 or more, even more preferably 7 or more, and still more preferably 8 or more, from the viewpoint of suppressing a decrease in detergency, and is preferably 20 or less, more preferably 16 or less, even more preferably 13 or less, and still more preferably 10 or less, from the viewpoints of ease of use and storage.
From the viewpoint of ease of use, the major axis diameter of the maximum projected area of the cleaning article of the present invention is preferably 30 mm or more, more preferably 50 mm or more, even more preferably 80 mm or more, and preferably 200 mm or less, more preferably 160 mm or less, even more preferably 120 mm or less.

In the present invention, the maximum projected area is the area of the projection that has the maximum horizontal projected area when the cleaning article is projected horizontally from all sides. "Projection" is the same as "projection" used in mathematics, that is, it means projecting a parallel light beam horizontally onto an object and projecting the shadow onto a flat surface.
In the present invention, the method for measuring the major axis diameter and minor axis diameter of the maximum projected area of the detergent article is as follows: when the shape of the maximum projected area of the detergent article is elliptical, the major axis diameter and minor axis diameter are measured as they are. When the shape of the maximum projected area of the detergent article is rectangular (length of vertical axis > length of horizontal axis), the length of the vertical axis is measured as the major axis diameter and the length of the horizontal axis is measured as the minor axis diameter. When the shape of the maximum projected area of the detergent article is irregular, the longest part is measured as the major axis diameter, and the longest part of the line (axis) perpendicular to the major axis diameter is measured as the minor axis diameter.
The maximum projected area of the cleaning article includes the water-soluble film that packages the cleaning composition, and also includes overlapping portions of the water-soluble films, such as sealed portions.
For example, when two water-soluble films are laminated together to package a detergent composition with the water-soluble film, the larger the contact area of the water-soluble film with the detergent composition, the more preferable. When two water-soluble films are laminated together to package a detergent composition with the water-soluble film, the ratio of the contact area of the water-soluble film with the detergent composition to the total area of the surface facing the other water-soluble film per water-soluble film is preferably 60% or more, more preferably 70% or more, even more preferably 80% or more, even more preferably 90% or more, and less than 100%. In this specification, the contact area of the water-soluble film with the detergent composition may be the area of the water-soluble film surface that forms the space for accommodating the detergent composition.
In addition, the detergent article may have an end of a water-soluble film packaging a detergent composition connected in a detachable manner to an end of a water-soluble film packaging another detergent composition. In such a case, the aspect ratio (long axis diameter/short axis diameter) between the major axis diameter of the maximum projected area of the detergent article and the minor axis diameter perpendicular to the major axis diameter is measured based on the calculated maximum projected area by calculating the maximum projected area of the detergent article for each water-soluble film packaging a detergent composition. That is, in the case of a detergent article in which the ends of the water-soluble films packaging a detergent composition are connected in a detachable manner, the aspect ratio is measured by cutting off the connected portion of the water-soluble film packaging the detergent composition. In addition, when the connected portion is unknown, a line dividing each packaged detergent composition into equal parts can be regarded as the connected portion.

2. Preparation of artificially soiled cloth with muddy soiling A muddy soiled cloth was prepared by the method described in paragraphs 0030 to 0038 of JP-A-10-204769 using 10 cm x 10 cm cotton knit (100% cotton, purchased from Tanigashira Shoten).

3. Evaluation of cleaning ability Each of the artificially soiled cloths, ie, cloths artificially soiled with sebum stains and cloths artificially soiled with mud stains, was cleaned by the following method, and the cleaning ability was evaluated.
Four pieces of artificially soiled cloth were washed in a tergotometer (MS-8212, manufactured by Ueshiba) at 100 rpm for 10 minutes. The specific washing conditions were as follows: four pieces of artificially soiled cloth and 0.30 g of each detergent composition shown in Table 1 were placed in the tergotometer, 600 mL of water was poured in, and a washing solution was prepared while dissolving the detergent composition in water, and at the same time, the artificially soiled cloth was washed at 100 rpm for 10 minutes. The water temperature of each washing solution was 20° C.
After washing, the stained cloth was rinsed with city water (20° C.) for 1 minute, and then dehydrated for 3 minutes using a two-layer washing machine, and then left to dry for 5 hours under conditions of 20° C. and 50% RH.
The cleaning rate (%) was calculated based on the following formula (1) and the average value of the four pieces was calculated. The reflectance at a wavelength of 550 nm of the original artificially soiled cloth and the artificially soiled cloth before and after cleaning was measured using a spectrophotometer (SE2000, manufactured by Nippon Denshoku Co., Ltd.). The results are shown in Table 1. The higher the cleaning rate, the more excellent the cleaning power of the cleaning composition.
Cleaning rate (%) = 100 × [(reflectance of artificially soiled cloth after cleaning - reflectance of artificially soiled cloth before cleaning) / (reflectance of original cloth - reflectance of artificially soiled cloth before cleaning)] (1)

<Evaluation of rinsing ability>
1. Evaluation of foam remaining To a drum-type washing machine (NA-VG1000L, Panasonic), 40 g of the detergent composition in Table 1, 3 sets of pants (UNIQLO), sweatshirt (UNIQLO), boxer shorts (UNIQLO), socks (UNIQLO), and long-sleeved top (Heattech, UNIQLO), and a cotton T-shirt (YG, Gunze) were added so that the total weight was 7.5 kg, and washing was performed with a standard course, washing for 9 minutes, rinsing once, and spin-drying for 6 minutes. The washing tub of the drum-type washing machine after the washing process was visually observed from the front of the drum-type washing machine, and foam remaining was evaluated according to the following evaluation index. The results are shown in Table 1. A detergent composition rated as "0" in the evaluation of foam remaining is a cleaning composition with excellent rinsing properties.
Evaluation index of remaining foam 0: The remaining amount of foam is less than 1/4 of the washing tub 1: The remaining amount of foam is 1/4 or more of the washing tub

2. Evaluation of turbidity A portion of the drainage of the rinse water after the first rinse step performed after the washing step in the drum washing machine was stored in a basin (diameter 30 cm, height 13.5 cm) at 5 L. A sticker with black letters of font size 18 was attached to the bottom of the basin in advance. With the rinse water stored in the basin, the letters attached to the bottom of the basin were visually observed from a position 0.7 m away directly above the surface of the rinse water. Evaluation was performed by five panelists based on the following indexes, and the total value of the evaluations of the five panelists was calculated. The results are shown in Table 1.
A cleaning composition having a low total score for the evaluation of turbidity by each panelist, or even a total score of "0", is a cleaning composition having excellent rinsing properties.
Turbidity evaluation index 0: The letters attached to the bottom of the tub were recognizable.
1: The letters attached to the bottom of the tub could not be recognized.

<Evaluation of antibacterial performance>
1. Antibacterial Test Method (1) Preparation of Fabric for Antibacterial Test 30 g of cotton fabric (cotton #2003, Tanigashira Shoten Co., Ltd.) and 600 mL of cleaning solution containing 0.3 g of each detergent composition listed in Table 1 were placed in a tergotometer, and the fabric was washed at 85 rpm for 10 minutes and rinsed for 3 minutes for a total of five cycles to prepare a test fabric. Boiled and sterilized tap water was used for all water.
(2) Antibacterial Test Using Moraxella osloensis isolated from worn clothing, an antibacterial test was carried out in accordance with JIS L 1902. Specifically, the test was carried out as follows.
The test cloth prepared by the method in (1) above was cut into test pieces of 2 cm square (each piece had a mass of approximately 0.4 g) to be used as specimens.
(i) Moraxella osloensis isolated from worn clothing was streaked on a plate with SCD-LP agar medium, and the resulting cultured specimen was scraped off with a platinum loop and placed in 10 mL of nutrient (NT) medium and pre-cultured for 24 hours at 37°C and 110 rpm. The concentration of the pre-cultured culture solution was estimated by spectrophotometry, and the bacterial concentration was adjusted to about 1 x 10 ⁸ cells/mL. The culture was then further diluted with 1/20 NT medium to adjust the bacterial concentration to 1 x 10 ⁵ cells/mL, and used as a test bacterial solution.
(ii) Exactly 0.2 mL of the test bacteria liquid was taken with a pipette, and each specimen or untreated standard cloth (JIS L 1902 standard cloth) was contacted with the liquid at several points, placed in a vial, and cultured at 37° C. for 18 hours with the lid closed. Inoculation with the test bacteria liquid and culture were performed multiple times for each of the specimens and standard cloth.
(iii) Five standard cloths after culture and five standard cloths immediately after contact were randomly selected, 20 mL of LP dilution for washing was added, the lid was closed, and the test was stirred for 30 seconds to wash away the bacteria, and the number of bacteria was counted. Five specimens after culture were randomly selected, 20 mL of LP dilution for washing was added to each specimen, the lid was closed, and the test was stirred for 30 seconds to wash away the bacteria, and the number of bacteria was counted.
The bacteriostatic activity value was calculated by the following formula. The results are shown in Table 1. A higher bacteriostatic activity value indicates higher antibacterial performance.
Bacteriostatic activity value = Log B - Log C
A: The average number of bacteria recovered from the control cloth immediately after inoculation. B: The average number of bacteria recovered from the control cloth after 18 hours of culture. C: The average number of bacteria recovered from the specimen after 18 hours of culture. However, this must satisfy the test validity condition, that is, Log B - Log A must exceed 1.5.

<Evaluation of residual dissolution>
The residual dissolution property of each of the cleaning compositions of the Examples and Comparative Examples in Table 1 was evaluated based on the presence or absence of streaks on the cleaned object and the diameter of the residual dissolution property of the cleaning composition that remained after cleaning. The residual dissolution property was evaluated by the following method.
40 g of each detergent composition in Table 1 was placed on a black cotton cloth (black dyed cotton broadcloth 40, purchased from Tanigashira Shoten) cut to 15 cm x 15 cm, and the detergent composition was wrapped around the cloth and woven. 7 kg (about 70 pieces) of cotton T-shirts (YG, manufactured by Gunze Co., Ltd.) were prepared, and 4 kg of the T-shirts were first placed in a fully automatic washing machine (NA-FR80H 68 kg, manufactured by Panasonic Co., Ltd.), the black cotton cloth wrapped with the detergent composition was placed on top of the T-shirts, and the remaining 3 kg was placed on top of the T-shirts. Washing was started using tap water (Wakayama City water) adjusted to 5°C, with the automatic cycle (water volume 60 L), washing for 9 minutes, rinsing once, and spin drying for 7 minutes.

1. Presence or absence of streaks remaining After washing, the black cotton cloth was visually inspected to confirm the presence or absence of streaks remaining on the black cotton cloth. The presence or absence of streaks remaining was evaluated by five panelists on one piece of black cotton cloth based on the following criteria, and the total score of the five panelists was calculated. The results are shown in Table 1. A detergent composition with a small total score of the five panelists' evaluations and little streaks remaining is a detergent composition with excellent solubility and improved insolubility.
Evaluation index for the presence or absence of streaks 0: No streaks at all 1: Streaks present

2. Evaluation of Undissolved Residue The undissolved residue of the detergent composition on the black cotton fabric was collected, and the maximum diameter (mm) of the collected residue was measured with a vernier caliper.
The undissolved residue of each cleaning composition was evaluated based on the following indexes. The results are shown in Table 1. If the undissolved residue was evaluated as 0 or 1, the cleaning composition was evaluated as having sufficient solubility, and it is preferable that the undissolved residue was evaluated as 0.
Evaluation index for undissolved residue 0: No undissolved residue at all 1: Clumps of the detergent composition measuring 1 mm or more and 5 mm or less were observed.
2: Clumps of the detergent composition measuring 5 mm or more were observed.

[Reference Example]
The following is an example of a detergent article including the detergent composition of the present invention and a water-soluble film for packaging the detergent composition. The detergent article can have a burst strength of 300 N or more in the burst strength measurement shown below, and can suppress a decrease in detergency even when the detergent composition is packaged in a water-soluble film in the cleaning performance evaluation shown below.

<Preparation of cleaning article>
For each reference example, two sheets of 76 μm water-soluble film (M8685, manufactured by Kuraray Co., Ltd.) cut to a predetermined rectangular size were stacked, and a heat sealer (manufactured by Fuji Impulse Co., Ltd.) was used to set the sealing conditions of the heat sealer to 8, and three sides of the water-soluble film were fused by the heat sealer at a width of 2 mm from the edge of each side to prepare a bag with only one side open. 15 g of the detergent composition of Examples 1-4 in Table 1 was placed in this bag for each reference example. Then, the open side of the bag was fused and closed with a heat sealer to obtain each cylindrical detergent article in which the detergent composition was encapsulated in the water-soluble film. The maximum projected area of each of the obtained detergent articles was rectangular, and the major axis diameter of the maximum projected area and the aspect ratio (major axis diameter/minor axis diameter) between the major axis diameter and the minor axis diameter perpendicular to the major axis diameter were as shown in Table 2. The total area of the water-soluble film in contact with the detergent composition was 48 cm ² . In addition, in measuring the maximum projected area, the area of the sealed portion of the water-soluble film is included in the maximum projected area.
The total area of the water-soluble film in contact with the detergent composition is calculated as twice the product of the length of the major axis diameter of the detergent article excluding the sealed portion (4 mm) and the length of the minor axis diameter of the detergent article excluding the sealed portion (4 mm), and is 30.4 cm ² , 34.2 cm ² , 35.6 cm ² , 37.1 cm ² , and 38.6 cm ² for Reference Examples 1 to 5, respectively.

<Measurement of burst strength>
Burst strength is measured for each of the detergent articles in Table 2. Under the conditions of room temperature (20°C)/relative humidity of about 50%, a compression tester (AUTOGRAPH AG-X, Shimadzu Science Co., Ltd.) is used to place each detergent article so that the surface with the maximum projected area is in contact with a fixed platen (not a spherical type, and having an area larger than the maximum projected area of each detergent article) of the compression tester, and a compressive force of 300N is applied at a speed of 200mm/min to perform evaluation. This measurement shows that none of the detergent articles of each reference example bursts at a compressive force of 300N, indicating that the burst strength is 300N or more.

<Evaluation of cleaning ability>
Preparation of Model Sebum Soil A model sebum soil having the following composition is prepared and used to prepare an artificial soiled cloth containing the model sebum soil.
・Model sebum stain composition:
0.44% by mass of lauric acid, 3.15% by mass of myristic acid, 2.35% by mass of pentadecanoic acid, 6.31% by mass of palmitic acid, 0.44% by mass of heptadecanoic acid, 1.6% by mass of stearic acid, 7.91% by mass of oleic acid, 13.33% by mass of triolein, 2.22% by mass of n-hexadecyl palmitate, 6.66% by mass of squalene, and the balance being water (total 100% by mass)

Preparation of Artificially Soiled Cloth The artificially soiled cloth used was prepared by gravure coating a 6 cm x 6 cm cotton/polyester broadcloth (cotton/polyester ratio = 35/65, purchased from Tanigashira Shoten) with the model sebum soiling composition described above at 100 mg per sheet.

Washing method Four artificially soiled cloths were sewn onto the chest of a cotton T-shirt (Gunze Co., Ltd.). A vertical washing machine (NA-F70PB1, Panasonic Co., Ltd.) was used. The detergent article of each Reference Example in Table 2 was placed at the bottom of the washing tub, and then the cotton T-shirt (Gunze Co., Ltd.) was added so that the total weight was 2 kg.
In each of the reference examples, water was added so that the concentration of the detergent composition contained in the detergent article in the washing tub was 0.5 g/L, and the washing was performed for 9 minutes, 1 rinse, and 7 minutes spin-dry time. The temperature of the water used for washing and rinsing was 20° C.
In addition, instead of each detergent article, the detergent composition of Example 1-4 in Table 1 that is not packaged in a water-soluble film is put into the washing tub, and the same washing method as above is carried out. This is used as a reference example.

Evaluation of cleaning ability The four pieces of artificially soiled cloth sewn onto the cotton T-shirt were removed, and the cleaning rate was measured by the following method, and the average value of the four pieces was calculated.
The reflectance at 550 nm of the unsoiled raw cloth and the artificially soiled cloth before and after washing was measured using a spectrophotometer (SE-2000, manufactured by Nippon Denshoku Co., Ltd.). The cleaning rate (%) was calculated using the following formula, and the average value of the four pieces was calculated.
Cleaning rate (%) = 100 x [(reflectance after cleaning - reflectance before cleaning) / (reflectance of original fabric - reflectance before cleaning)]
The cleaning rate of each Reference Example is calculated by taking the cleaning rate of a Reference Example using a cleaning composition not packaged in a water-soluble film as 100%, and calculating the relative cleaning rate (%) to the Reference Example. Each of the cleaning articles in Table 2 can increase the relative cleaning rate, and can suppress a decrease in cleaning power even when the cleaning composition is packaged in a water-soluble film.
