The alkalinity is calculated by the following formula.
Alkalinity (CaCO ₃ mg / l) = a × 10
Here, a: 10 mmol / l sulfuric acid (ml) required for titration.
When the color change due to the indicator is not clear, such as a colored sample, a pH meter is used instead of the indicator, and the amount of 10 mmol / l sulfuric acid (ml) required until the pH value is 4.8 is defined as a.

<Evaluation of foamability during rinsing>
The cleaning liquid used in the above “evaluation of foaming property during cleaning” was diluted 100 times by mass with water having a German hardness of 10 ° dH (Ca / Mg = 7/3) and an alkalinity of 60 to obtain a rinse liquid. Corresponding solutions were prepared. 200 g of the solution corresponding to the rinsing liquid is poured into a cylindrical glass container (inner diameter: 5 cm, inner height: 90 cm) with one side closed and the other side open over 30 seconds. The foam height 5 minutes after pouring was measured. The height of the foam was measured by measuring the height of the foam in contact with the inner wall of the glass container. When the height of the foam was 10 mm or less, it was judged that the foaming property during rinsing was good. The smaller the number, the better the foaming property when rinsing.

<Evaluation of cleaning power>
5 liters of AS-10 artificially contaminated cloth (made by Testfabrics, cut into 10 cm × 10 cm) was placed in 1 L of a cleaning liquid obtained by mixing a liquid cleaning composition for clothing and water, and after immersion for 30 minutes, a targotometer ( Ueshima MS-8212, inner diameter 12 cm, height 17.5 cm) was washed at 100 r / min for 3 minutes. The concentration of the liquid detergent composition in the cleaning liquid was 0.4% by mass. The water used for the preparation of the cleaning liquid was water having an alkalinity of 60, in which calcium chloride was added to ion-exchanged water, and the German hardness was adjusted to 10 ° DH (178 mg CaCO ₃ / L). The water temperature of the cleaning liquid was 30 ° C., and this temperature was maintained during the immersion of the artificially contaminated cloth. After washing, rinsing was performed with the same mass of ion-exchanged water for 1 minute.

The detergency was determined by measuring the reflectance at 550 nm of the raw cloth before contamination and the contaminated cloth before and after washing with a self-recording colorimeter (Shimadzu Corporation), and obtaining the washing rate (%) by the following formula. The washing rate was measured from the reflectance of each of the five contaminated cloths, and the average value was calculated.
As a result of evaluating the detergency of the washing rate of the liquid detergent composition for clothing according to the present invention described in Tables 3 and 4, the average value of the washing rate of each composition was 30% or more, and the liquid washing for clothing It was confirmed to have general detergency as an agent composition.

<Evaluation of foaming property at the time of washing and foaming property at the time of rinsing>
Evaluation clothing Three men's L-sized round neck underwear (manufactured by Gunze Co., Ltd., trade name Gunze YG, 100% cotton, about 100 g / 1) were used as evaluation clothing.

・ Evaluation operation (washing)
A polypropylene basin with a diameter of 36 cm, a depth of 13 cm, and a capacity of 11 L. Calcium chloride is added to ion-exchanged water to adjust the German hardness to 10 ° DH (178 mg CaCO ₃ / L). The alkalinity is 60 and the temperature is 30 ° C. 3 L of water, 12 g of a liquid cleaning composition for clothing, and 0.5 mL of the model sebum stain were placed. Subsequently, it stirred for 30 seconds by hand so that water might not scatter from a washbasin, and prepared the washing | cleaning liquid.
Three pieces of evaluation clothing in which 0.1 mL of the model sebum stain was applied per piece of evaluation clothing was immersed in the cleaning solution in the basin, and the whole was stirred for 30 seconds and then immersed in the cleaning solution for 30 minutes. After the immersion, the evaluation garment was lifted from the surface of the cleaning liquid to such an extent that the cleaning liquid did not scatter from the basin, and then washed back into the cleaning liquid for 1 minute per evaluation garment. Then, after squeezing by hand above the basin so that the water content with respect to the evaluation garment is about 40 to 60%, the evaluation garment was taken out from the basin.
This operation was performed continuously, and the height of the foam was measured immediately after all the clothing for evaluation was taken out. This was taken as the height of the foam at the time of washing.
A larger value for the height of the foam is preferred. The height of the foam of 1.2 cm or more is the height at which the liquid level is difficult to see due to the foam generated by the 3rd evaluation clothing. That's it. Therefore, if the height of the foam is 1.2 cm or more, it can be determined that a foaming property that can be satisfied by a person performing hand-washing is obtained.

・ Evaluation operation (rinse)
Rinse water with a alkalinity of 60 with a temperature of 30 ° C, calcium chloride added to ion-exchanged water, and a German hardness adjusted to 10 ° DH (178 mgCaCO ₃ / L) for a washbasin 30 cm in diameter and 12 cm in depth 3 L of water and three evaluation clothes taken out from the wash basin by the “evaluation operation (washing)” were put. Evaluation clothes were loosened in rinse water. Next, the operation of lifting the neck of the evaluation clothing from the surface of the rinsing water while opening the neck portion of the clothing for evaluation with both hands so that the rinsing water also passes inside the clothing for evaluation was repeated 10 times. Subsequently, after squeezing by hand so that the water content with respect to the apparel for evaluation was about 40 to 60%, it was taken out from the washbasin. Furthermore, this series of operations was repeated once more. This series of operations was performed for each piece of clothing for evaluation.
The state of the water surface immediately after taking out all the apparel for evaluation was observed, and points were assigned according to the following criteria to evaluate rinsing properties.
If the remaining amount of foam is less than 2/3 of the liquid level, it can be determined that the person performing hand-washing has good foam loss when rinsed. Therefore, if the following points are 3 or less, it can be judged that the foaming property which a person performing hand-washing can satisfy is obtained.

Point 5: Bubbles remain on almost the entire liquid surface 4: Bubbles remain on 2/3 or more of the entire liquid surface 3: Bubbles remain on 1/3 or more and less than 2/3 of the liquid surface 2: Bubbles remain below 1/3 of the liquid level 1: Little bubbles remain on the liquid level
