Next, 16 mL of liquid detergent for clothing (JAFET standard detergent) was added, washed, rinsed and dehydrated in the standard course of the washing machine, and the cotton shirt was washed. The washed cotton skin shirt was dried by a standard course of an electric dryer for clothes (manufactured by TOSHIBA, ED-45C).
Clothing from the wearing to washing and drying was repeated 20 times and stored in a drawer shelf at room temperature for 6 months to obtain test clothing. A cloth with a size of 5 cm × 5 cm was cut out from the body of the test garment, and the reflectance was measured with a colorimetric color difference meter (“SE2000” manufactured by Nippon Denshoku Co., Ltd.). The b values were almost the same (b value = 8 ± 0.5) was used as an evaluation cloth (an evaluation cloth before washing).
<Evaluation method>
The five evaluation cloths were spread so as not to overlap the plastic petri dish, and 0.3 mL of the liquid cleaning agent of each example was dropped on each evaluation cloth, and left at room temperature for 10 minutes. The evaluation cloth after standing and 43 g of the charge cloth (cotton knitted cloth) were placed in a washing tester (Terg-O-Tometer) together with 900 mL of tap water (15 ° C., 3 ° DH hard water) and washed at 120 rpm for 10 minutes. . After washing, dehydration was performed, and rinsing was performed for 3 minutes with 900 mL of tap water (15 ° C., 3 ° DH hard water). The evaluation cloth after the rinsing was dehydrated and dried with an iron as an evaluation cloth after washing.
For the evaluation cloth before washing and the five evaluation cloths after washing, the reflectance was measured with a colorimetric color difference meter (“SE2000” manufactured by Nippon Denshoku Co., Ltd.), and the washing rate (%) was calculated from the following formula (s). did.
Washing rate (%) = 100 × (reflectance of evaluation cloth before washing−reflectance of evaluation cloth after washing) / (reflectance of evaluation cloth before washing−reflectance of uncontaminated cloth) (s) )
In the formula (s), the uncontaminated cloth is a cloth cut into a size of 5 cm × 5 cm from the trunk of a new cotton skin shirt (BVD, 100% cotton).
The average value of the cleaning rates of the five evaluation fabrics was defined as the cleaning power, and the cleaning power against yellowing was evaluated according to the following criteria. ◎, ○, and △ were considered acceptable.
[Judgment criteria for detergency against yellowing]
A: 30% or more.
○: 25% or more and less than 30%.
Δ: 15% or more and less than 25%.
X: 0% or more and less than 15%.

From the results shown in Tables 1 and 2, it was confirmed that the liquid detergents of Examples 1 to 20 to which the present invention was applied were excellent in the foaming reduction effect and excellent in detergency against clothing yellowing.
On the other hand, the liquid detergents (Comparative Examples 1 and 2) not containing the component (A) or the component (B) did not have sufficient cleaning power against yellowing of clothes.
The liquid detergent (Comparative Example 3) that does not contain the component (C) and the liquid detergent (Comparative Example 4) that uses the component (A ′) instead of the component (A) did not have sufficient foaming reduction effects. .
From the above results, it was confirmed that the liquid detergent to which the present invention was applied was excellent in the foaming reduction effect and excellent in the cleaning power against clothing yellowing.
