After stirred for 10 minutes, the contents were transferred to a water bath filled with water at 5° C. and cooled while stirred until the temperature of the contents reached 25° C. Using a pH meter equipped with a glass pH electrode, the pH was adjusted to a predetermined level by adding the pH adjuster. Ion exchange water was added to make the contents 100 mass %. The pH of the final compositions was measured and listed in Tables 1 and 2. A method for measuring pH is as follows. Note that, in Tables 1 and 2, the content of each formulation component is the amount of an active component.

<Method for Measuring pH>

[0206] A composite electrode for pH measurement (manufactured by HORIBA, Ltd., glass slide-in sleeve type) was connected to a pH meter (pH/ion meter F-23 manufactured by HORIBA, Ltd.), and the power was turned on. A saturated potassium chloride aqueous solution (3.33 mole/L) was used as an internal solution of the pH electrode. Next, a pH 4.01 standard solution (phthalate standard solution), a pH 6.86 standard solution (neutral phosphate standard solution) and a pH 9.18 standard solution (borate standard solution) were each filled into 100 mL beakers, which were immersed in a thermostatic bath at 25° C. for 30 minutes. Calibration operation was performed in the order of pH 6.86, pH 9.18 and pH 4.01 by immersing the electrode for pH measurement in each of the standard solutions adjusted to the constant temperature for 3 minutes. A sample to be measured was adjusted to 25° C.; the electrode of the pH meter was immersed in the sample; and the pH was measured 1 minute later.

<Washing Test>

(1) Pre-Washing of Test Cloth

[0207] Commercially available TC broadcloth (cotton/polyester ratio=65/35, purchased from Senshoku Shizai Kabushikikaisha Tanigashira Shoten) was cut into sheets each with a size of 1 m×1 m, which were prepared as many as a number equivalent to a mass of about 1.5 kg. EMULGEN 108 (polyoxyethylene alkyl ether, manufactured by Kao Corporation) was dissolved in city water in an amount of 500 mg/kg and washing operation was performed three times in an automatic washing machine (manufactured by TOSHIBA CORPORATION, model number: AW-8D3M). The bath ratio was 20 and the water temperature was 15° C. After that, they were rinsed under running water until no bubbles appeared, dried, and then used.

(2) Preparation of Curry-Soiled Cloth

[0208] The pre-washed sheets of TC broadcloth were cut into 6 cm×6 cm pieces, three of which were stacked on top of one another, coated with 50 μl of curry (Soot Thai Red Curry, purchased at Kaldi) heated in a thermostatic bath at 50° C. in the shape of a circle with a diameter of 1 cm, and then, left to stand for 20 minutes under the circumstance at 23° C. and 50% RH. The top one of the three stacked pieces was used as a piece of curry-soiled cloth.

(3) Method of Washing Test

[0209] A sheet-like spunlace nonwoven fabric (rayon/polypropylene/polyester ratio=80/10/10, basis weight 60 g/m.sup.2, 150 mm×100 mm) was impregnated with each of the detergent compositions listed in Tables 1 and 2 at an impregnation rate of 350 mass % relative to the mass of the nonwoven fabric to prepare a wet nonwoven fabric. A wiping test was conducted such that the stained surface of the piece of curry-soiled cloth was wiped with the wet nonwoven fabric 50 times. Note that, in the wiping test with the wet nonwoven fabric, washing operation was performed such that, every 10 times the stain attached to the textile product was wiped with one surface of the wet nonwoven fabric making contact therewith, the surface was changed to the other, with which the stain was wiped. After wiped, the piece of curry-soiled cloth was left to stand for 12 hours under the circumstance at 25° C. and 60% RH.

(4) Method for Evaluating Detergency

(4-1) Method for Evaluating Stain Removal Rate

[0210] The reflectance of the stained surface of the piece of curry-soiled cloth after left to stand was measured (with NF777 manufactured by NIPPON DENSHOKU INDUSTRIES CO., LTD., range to be measured: a circle with a diameter of 5 mm at the center of the stain). A stain removal rate was calculated by the following formula, and the average value from measurements of three different pieces of curry-soiled cloth is listed in Tables 1 and 2. Note that reflectance (Z value) before wiping is Za, a Z value after wiping is Zb, and a Z value of white cloth is Zo.

Stain removal rate (%)=(Zb−Za)/(Zo−Za)×100

[0211] The higher a value of the stain removal rate is, the more excellent detergency is, and those with a stain removal rate of 70% or more are preferable.

(4-2) Method for Evaluating Stain Spreading Rate

[0212] Before and after the washing test in (3), the piece of cloth was subjected to image analysis using a scanner (manufactured by SEIKO EPSON CORPORATION, model type: GT-X820). The area of a range in which the stain was attached was determined and compared with the area of the stain before the washing test, and a stain spreading rate was calculated by the following formula. The average value of the stain spreading rates of three different pieces of curry-soiled cloth is listed in Tables 1 and 2.

Stain spreading rate (%)=(area of stain after washing)/(area of initial stain)×100

[0213] The smaller a value of the stain spreading rate is, the less a stain is spread out by wiping, and those with a stain spreading rate of 150% or less are preferable.
