[0058] As compound (c2), polyoxyethylene fatty acid alkyl ester is preferable, particularly R in formula (c2) 33 is an alkyl group having 11 carbon atoms and an alkyl group having 13 carbon atoms, -X- is -COO-, and R 34 is a methyl group, s2 = 15, t2 = 0, and u2 = 0 (hereinafter sometimes referred to as MEE) is more preferable. Polyoxyethylene fatty acid alkyl ester, particularly MEE, is a nonionic surfactant with weak orientation between molecules and unstable micelles in an aqueous solution system. For this reason, polyoxyethylene fatty acid alkyl ester does not cause gelation or the like at high concentrations, and it is presumed that even if it is blended in a large amount in the detergent composition alone, its solubility in water can be enhanced. Therefore, it is considered that when the detergent composition containing polyoxyethylene fatty acid alkyl ester comes into contact with water, it is quickly dispersed to form a cleaning liquid. Also, the concentration of polyoxyethylene fatty acid alkyl ester in the cleaning liquid quickly becomes uniform, and a cleaning liquid with an appropriate concentration can be brought into contact with the object to be cleaned (textile product) from the initial stage of cleaning. As a result, it is considered that high detergency can be exhibited.

In addition, yellowing and pigment fading of the detergent composition can be more suppressed, and a uniform appearance can be maintained well. The pH of the detergent composition can be adjusted with a pH adjuster. The pH of the detergent composition is a value measured at 25°C for the measurement target with a pH meter (manufactured by Toa DKK Corporation, product name "HM-30G").

[0092] <Manufacturing method> The manufacturing method of the detergent composition is not particularly limited, and the detergent composition can be manufactured according to a conventional method. For example, the detergent composition can be obtained by mixing the components constituting the detergent composition. Also, for example, the above-mentioned component (A), component (B), component (C), a part of water, and one or more optional components other than the pH adjuster, if necessary, are mixed, and if necessary, adjusted to a predetermined pH using a pH adjuster, and then the remaining water is mixed to manufacture the detergent composition.

[0094] In recent years, it is also preferable to use a washing machine equipped with a detergent automatic dosing device. The detergent automatic dosing device is a device that automatically doses a detergent composition into a washing tub from a tank containing the detergent composition, via a dust removal filter provided at the bottom of the tank and a dosing pipe. A metering means such as a syringe pump is provided in the middle of the dosing pipe, and a fixed amount set according to the amount of laundry can be transferred from the tank to the washing tub. By using the detergent automatic dosing device, not only can the labor of metering be saved, but also it is possible to avoid the detergent composition adhering to the hands or spilling during metering, thereby soiling the washing machine and its surroundings.

[0095] It is also preferable to use an automatic dispenser that can automatically discharge a predetermined amount of liquid. Even when using an automatic dispenser, it is possible to accurately measure even a small amount of the detergent composition, so it is easy to exhibit sufficient detergency and avoid waste due to overuse, which is preferable. Among automatic dispensers, there are also commercially available ones that use an infrared sensor or the like to automatically discharge without touching a switch or the like. By using such an automatic dispenser, it is possible to measure the detergent composition simply by inserting a container held in one hand, and the effect of reducing the burden on the user is great.

[0096] When using an automatic dispenser, it is also preferable to receive the detergent composition discharged into a soft container and directly put the soft container into the washing machine. Thereby, it is possible to surely dissolve the entire amount of the discharged detergent composition in the washing liquid. Examples of the material of the soft container that can be directly put into the washing machine include, for example, silicone resin, polyvinyl chloride, elastomer, soft polyester, soft polypropylene, polyurethane, etc.

[0097] Examples of the objects to be washed include, for example, fibrous products such as clothing (apparel), dishcloths, towels, sheets, curtains, etc. The material of the fibrous product is not particularly limited, and it may be any of natural fibers such as cotton, silk, wool, and chemical fibers such as polyester and polyamide. When the cleaning composition is dissolved in water for use, it is preferably diluted, for example, 5 to 6,000 times (by volume). The bath ratio (mass of cleaning liquid during washing / mass of clothing), which is the amount of water per amount of clothing, is preferably 5 or more for a drum washing machine and 10 or more for a vertical washing machine.

[0098] <Function and effect> In addition to the component (C) described above, the cleaning composition of the present embodiment described above contains the components (A) and (B) in a specific mass ratio and content, and thus has excellent detergency against sebum stains and mud stains. In addition, since the viscosity increase of the cleaning composition of the present embodiment is suppressed by the viscosity reduction effect, it has excellent usability. In addition, the cleaning composition of the present embodiment also has excellent liquid stability.

[0103] <Synthesis method of C1-1> 861.2 g of natural alcohol (manufactured by Procter & Gamble, trade name "CO-1214") and 2.0 g of a 30% by mass aqueous NaOH solution were charged into a pressure-resistant reaction vessel, and the inside of this reaction vessel was purged with nitrogen. Then, after dehydration at a temperature of 100 °C and a pressure of 2.0 kPa or less for 30 minutes, the temperature was raised to 160 °C. Next, while stirring the reaction solution, 355.0 g of ethylene oxide (gaseous) was gradually added to the reaction solution. At this time, ethylene oxide was added through a blowing tube while adjusting the addition rate so that the reaction temperature did not exceed 180 °C. After completion of the addition of ethylene oxide, aging was carried out at a temperature of 180 °C and a pressure of 0.3 MPa or less for 30 minutes, and then unreacted ethylene oxide was distilled off at a temperature of 180 °C and a pressure of 6.0 kPa or less for 10 minutes. Next, after cooling the temperature to 100 °C or less, 70% by mass of p-toluenesulfonic acid was added for neutralization so that the pH of a 1% by mass aqueous solution of the reaction product became 7, and C1-1 was obtained.

[0104] <Synthesis method of C1-2> C1-2 was obtained by the same synthesis method as C1-1, except that the amount of ethylene oxide (gaseous) added was changed to 760.6 g.

[0105] <Synthesis method of C1-3> Synthesis was carried out according to the synthesis method described in JP-A-2000-144179. Aluminum hydroxide-magnesium hydroxide (manufactured by Kyowa Chemical Industry Co., Ltd., trade name "Kyoward 300") with a composition of 2.5MgO·Al2O3·zH2O was calcined at 600 °C for 1 hour under a nitrogen atmosphere to obtain a calcined aluminum hydroxide-magnesium hydroxide (unmodified) catalyst. 2.2 g of the calcined aluminum hydroxide-magnesium hydroxide (unmodified) catalyst, 2.9 mL of 0.5N potassium hydroxide ethanol solution, 280 g of methyl laurate, and 70 g of methyl myristate were charged into a 4 L autoclave, and the catalyst was modified in the autoclave. Then, after replacing the inside of the autoclave with nitrogen, while maintaining the temperature at 180 °C and the pressure at 0.3 MPa, 1052 g of ethylene oxide was introduced and reacted with stirring. The obtained reaction solution was cooled to 80 °C, 159 g of water, 5 g of activated clay and 5 g of diatomaceous earth as a filter aid were added and mixed, and then the catalyst was filtered off to obtain C1-3.

[0106] <Synthesis method of C2-2> 400 g of natural alcohol (trade name "CO-1270" manufactured by Procter & Gamble) and 0.8 g of potassium hydroxide catalyst as a reaction catalyst were charged into a pressure-resistant reaction vessel. After replacing the inside of this reaction vessel with nitrogen, the temperature was raised with stirring. Next, while stirring the reaction solution, 91 g of ethylene oxide (gaseous) was gradually added to the reaction solution and reacted to obtain an alcohol ethoxylate. The ethylene oxide was added through a blowing tube while adjusting the addition rate so that the reaction temperature did not exceed 180 °C and the pressure did not exceed 0.3 MPa. Using a gas chromatograph: GC-5890 manufactured by Hewlett-Packard, a detector: a flame ionization detector (FID), and a column: Ultra-1 (manufactured by HP, L25m × φ0.2mm × T0.11μm), the resulting alcohol ethoxylate had an average molar number of ethylene oxide addition of 1.0. Also, the amount of the compound without added ethylene oxide was 43% by mass based on the total amount of the obtained alcohol ethoxylate. Next, 237 g of the alcohol ethoxylate obtained above was placed in a 500 mL flask equipped with a stirrer, purged with nitrogen, and then 96 g of liquid anhydrous sulfuric acid (sulfan) was slowly added dropwise while maintaining the reaction temperature at 40°C. After the addition was complete, stirring was continued for 1 hour (sulfation reaction) to obtain polyoxyethylene alkyl ether sulfate. Then, this was neutralized with an aqueous sodium hydroxide solution to obtain C2-2.

[0108] "Measurement and Evaluation" <Evaluation of detergency against sebum stains> As the contaminated cloth, a wet artificial contaminated cloth (manufactured by the Laundry Science Society, Inc., with a composition of 28.3% oleic acid, 15.6% triolein, 12.2% cholesteryl oleate, 2.5% liquid paraffin, 2.5% squalene, 1.6% cholesterol, 7.0% gelatin, 29.8% mud, 0.5% carbon black, and sebum stains adhered) cut into 5 cm × 5 cm pieces was used. As the washing tester, a Terg-O-tometer (manufactured by UNITED STATES TESTING) was used. As the washing solution, a solution prepared by adding the detergent composition to 900 mL of water (25°C, 5°DH) so that the concentration was 333 volume ppm and stirring for 30 seconds was used. 900 mL of the washing solution, 10 pieces of the contaminated cloth, and a washing cotton cloth were put into the washing tester, and the bath ratio was adjusted to 20 times, and washing was carried out at 120 rpm and 25°C for 10 minutes. Then, it was transferred to a two-tank washing machine (manufactured by Mitsubishi Electric Corporation, product name "CW-C30A1-H1"), rinsed in 30 L of water (25°C, 5°DH) for 3 minutes, dehydrated for 1 minute, and then air-dried. For the unstained cloth and the contaminated cloth before and after washing, the reflectance was measured with a color difference meter (manufactured by Nippon Denshoku Industries Co., Ltd., product name "SE7700 type"), and the washing rate (%) was calculated from the following formula (i). The "unstained cloth" is a white cloth (original cloth) to which no stain (sebum stain) is attached. Washing rate (%) = (K / S of the contaminated cloth before washing - K / S of the contaminated cloth after washing) / (K / S of the contaminated cloth before washing - K / S of the unstained cloth) × 100 ···(i) (In formula (i), K / S = (1 - R / 100) 2 / (2R / 100). R is the reflectance (%).)

[0109] The washing rate (%) was calculated for 10 contaminated cloths and the average value was obtained. Separately, as a detergent composition of the reference composition, using the detergent composition obtained in Comparative Example 1, the contaminated cloth was washed in the same manner, and the average value of the washing rate was obtained. The average value of the washing rate of the detergent composition obtained in Comparative Example 1 was 55%. The detergency against sebum stains was evaluated based on the following criteria. "◎", "○" and "△" were regarded as passing. (Evaluation criteria) ◎: The average value of the washing rate is significantly higher than that of Comparative Example 1, and the difference is 5% or more. 〇: The average value of the washing rate is higher than that of Comparative Example 1, and the difference is 3% or more and less than 5%. △: The average value of the washing rate is slightly higher than that of Comparative Example 1, and the difference is 1% or more and less than 3%. ×: The average value of the washing rate is equivalent to that of Comparative Example 1, and the difference is 0% or more and less than 1%.

[0110] <Evaluation of detergency against mud stains> As the red clay used for preparing the contaminated cloth, the reddish-yellow soil (Mikatahara, Shizuoka Prefecture) of the diluvial terrace was dried at 200 °C and pulverized to an average particle size of about 1 μm with a micron atomizer. The contaminated cloth was prepared as follows. First, weigh 20 g of the red clay, put it into 500 g of tap water, and disperse it at 80 rpm for about 10 minutes using a homogenizer (manufactured by KINEMATICA, product name "Polytron Type PT10 / 35") to obtain a mud dispersion. Into the obtained mud dispersion, immerse 15 pieces of cotton jersey knit fabric cut into 10 cm × 25 cm (a dyed sample manufactured by Taniguchi Shoten Co., Ltd., cotton knit not pre-siliconized), knead the cotton jersey knit fabric well by hand, and uniformly incorporate the mud dispersion throughout the cotton jersey knit fabric. Then, take out the cotton jersey knit fabric and gently squeeze it with a roller. After natural drying for 30 minutes, further dry it in a constant temperature bath at 105°C for 1 hour. Next, polish the surface of the cotton jersey knit fabric to remove excess mud particles, cut it into 3 cm × 4 cm, and use it as a contaminated cloth.

[0111] As a washing tester, a Terg-O-tometer (manufactured by UNITED STATES TESTING) was used. As a washing liquid, a preparation obtained by adding a detergent composition to 900 mL of water (25°C, 5°DH) so that the concentration becomes 333 volume ppm and stirring for 30 seconds was used. Into the washing tester, put 900 mL of the washing liquid, 10 pieces of contaminated cloth, and a washing cotton fabric, and adjust the bath ratio to 20 times, and wash at 120 rpm and 25°C for 10 minutes. Then, transfer it to a two-tank washing machine (manufactured by Mitsubishi Electric Corporation, product name "CW-C30A1-H1"), rinse it in 30 L of water (25°C, 5°DH) for 3 minutes, dehydrate it for 1 minute, and then air-dry it. For the non-soiled cloth and the contaminated cloth before and after washing, measure the reflectance with a color difference meter (manufactured by Nippon Denshoku Industries Co., Ltd., product name "SE7700 type"), and calculate the washing rate (%) from the above formula (i). Note that the "non-soiled cloth" is a cotton jersey knit fabric (original cloth) without adhering dirt (mud stain).

[0112] Calculate the washing rate (%) for 10 pieces of contaminated cloth and find the average value. Separately, as a detergent composition of a reference composition, use the detergent composition obtained in Comparative Example 1, and similarly wash and treat the contaminated cloth to find the average value of the washing rate. Note that the average value of the washing rate of the detergent composition obtained in Comparative Example 1 was 58%. The detergency against mud stains was evaluated based on the following criteria. "◎", "○", and "△" were regarded as passing. (Evaluation Criteria) ◎: The average value of the cleaning rate is significantly higher than that of Comparative Example 1, and the difference is 5% or more. 〇: The average value of the cleaning rate is higher than that of Comparative Example 1, and the difference is more than 3% and less than 5%. △: The average value of the cleaning rate is slightly higher than that of Comparative Example 1, and the difference is more than 1% and less than 3%. ×: The average value of the cleaning rate is equivalent to that of Comparative Example 1, and the difference is 0% or more and less than 1%.

[0113] <Evaluation of Usability> The detergent composition was placed in a 300 mL tall beaker and the temperature was adjusted in a constant temperature bath at 25°C. Then, using a No. 1 rotor with a B-type viscometer (manufactured by Toki Sangyo Co., Ltd.), the viscosity at 25°C was measured under the condition of 30 rpm, and the usability was evaluated based on the following criteria. "〇" was regarded as passing. (Evaluation Criteria) 〇: The viscosity is less than 150 mPa·s. ×: The viscosity is 150 mPa·s or more.

[0114] <Evaluation of Liquid Stability> A transparent glass bottle (wide-mouth standard bottle, PS-NO.11) was filled with 90 mL of the detergent composition, covered and sealed. It was left standing in a constant temperature bath at 25°C for 30 days for storage. The appearance of the detergent composition after storage was visually observed, and the usability was evaluated based on the following criteria. "◎", "〇", and "△" were regarded as passing. (Evaluation Criteria) ◎: No precipitate or other substances are observed and it is transparent. 〇: A very small amount of precipitate is observed but it is transparent. △: Precipitate occurs but it is transparent. ×: Precipitation occurs and it is opaque, or separation has occurred.

[0115] "Examples 1 to 21, Comparative Examples 1 to 5" Into a 500 mL beaker, the components (A), (B), and (C) and optional components were added according to the formulation compositions described in Tables 1 to 4, and thoroughly stirred with a three-one motor stirrer (manufactured by AS ONE Corporation) to obtain a detergent composition. The pH of the obtained detergent composition at 25 °C was measured using a pH meter (manufactured by Toa DKK Corporation, product name "HM-30G"). The results are shown in Tables 1 to 4. In addition, using the obtained detergent composition, evaluations of detergency, usability, and liquid stability against sebum stains and mud stains were performed. The results are shown in Tables 1 to 4.

[0116]

Table 1

[0117]

Table 2

[0118]

Table 3

[0119]

Table 4

[0120] In Tables 1 to 4, the blending amounts (mass %) of each component are all ratios to the total mass of the detergent composition, and except in cases where specified, the values are in terms of pure component conversion. Note that the "balance" which is the blending amount of water is the amount required to make the total blending amount (mass %) of all the blending components contained in the detergent composition 100 mass %. An empty cell in the blending amount means that the component is not blended (blending amount 0 mass %). Also, in Tables 1 to 4, the "C1 / C2 ratio" is the mass ratio of the content of component (C1) to the content of component (C2). The "A / B ratio" is the mass ratio of the content of component (A) or its substitute to the content of component (B).

[0121] As is clear from Tables 1 to 3, the detergent compositions obtained in each example were excellent in detergency against sebum stains and mud stains. They were also excellent in usability and liquid stability. On the other hand, as is clear from Table 4, the detergent composition (detergent composition of the reference composition) obtained in Comparative Example 1 that did not contain the component (A) and the component (B) was inferior in usability. The detergent composition obtained in Comparative Example 2 that did not contain the component (A) was inferior in detergency against mud stains and usability. Also, for example, compared with Examples 1 to 5, it was also inferior in detergency against sebum stains. The detergent composition obtained in Comparative Example 3 that did not contain the component (B) was inferior in detergency against mud stains. Also, for example, compared with Examples 1 to 5, it was also inferior in detergency against sebum stains. The detergent composition obtained in Comparative Example 5 that did not contain the component (A) and used a substitute for the component (A) (y / x less than 1) was inferior in detergency against mud stains. The detergent composition obtained in Comparative Example 5 where the A / B ratio was less than 1.0 was inferior in detergency against mud stains. Also, for example, compared with Examples 1 and 9, it was also inferior in detergency against sebum stains.
