In the table, the "B/C ratio" of Comparative Example 5 and Comparative Example 6 indicates the mass ratio of the component (B') to the component (C).

For each of the liquid detergents, the deodorizing effect (deodorizing effect (1), deodorizing effect (2)), recontamination prevention property, and appearance stability were evaluated as follows. The evaluation results are shown in Table 1.

[Evaluation of the deodorizing effect (1)] A cotton towel of about 100 g for one week in the actual household, and a cotton shirt of about one hundred forty years old for men in the age of 20 to 30 are about 700 g. Towels and cotton shirts are also collectively referred to as "clothing") and are put into fully automatic electric washing machines (JW-Z23A manufactured by Haier). Then, 10 mL of the liquid detergent of each example was put into the washing machine, and the laundry was washed, rinsed, and dehydrated by a standard procedure of the washing machine. Dry the washed clothes for a day and night. For the "unpleasant odor" of the clothes after drying, five male and female functional inspectors were scored by the following six levels of judgment criteria. The average value of the five scoring results was classified into the following evaluation criteria, and the deodorizing effect on the laundry was evaluated (1). Let △, ○, and ◎ be qualified. (Judgement criteria) 0 points: No smell. 1 point: The odor can be barely perceived. 2 points: Know which odor is the smell. 3 points: odor that can be easily perceived. 4 points: Strong smell. 5 points: Strong smell. (Evaluation criteria) ◎: 0 or more and less than 1.5 points. ○: 1.5 points or more and less than 2.5 minutes. △: 2.5 points or more and less than 3 points. ×: 3 minutes or more and 5 minutes or less.

[Deodorization effect (2): Evaluation of deodorization of ammonia odor] 5 mL of a 0.1 N aqueous ammonia solution was applied to the clothes of [Evaluation of deodorization effect (1)], and left for 1 hour. Then, a washing liquid in which 10 mL of the liquid detergent of each example was dispersed in 5 L of tap water was prepared, and the laundry was immersed in the washing liquid and left for 2 hours. Then, the laundry was taken out from the washing liquid and put into a fully automatic electric washing machine (JW-Z23A manufactured by Haier Co., Ltd.) to perform dehydration. In the "ammonia odor" of the clothing material after the dehydration, the taste appraisers of the five men and women in the same manner were scored and classified in the same manner as the evaluation of the [deodorizing effect (1)], and the deodorizing effect of the ammonia odor was evaluated (2). Let △, ○, and ◎ be qualified.

[Evaluation of Recontamination Prevention] 0.3 mL of the liquid detergent of each example was dispersed in 900 mL of 3 °DH hard water (25 ° C) to form a washing liquid. The washing liquid and the following laundry were placed in a Terg-o-tometer (manufactured by UNITED STATES TESTING Co., Ltd.) and washed at 120 rpm at 25 ° C. Wash for 10 minutes (washing treatment). (Washed): Cotton re-contamination judgment cloth: knitted cotton (manufactured by Tanitou Co., Ltd.) 5 × 5 cm···5 pieces. - Wet artificially contaminated cloth: manufactured by the Consortium Washing Science Association (stain composition: 28.3% oleic acid, 15.6% by mass of triolein, 12.2% by mass of cholesterol oleate, 2.5% by mass of liquid Paraffin, 2.5% by mass of squalene, 1.6% by mass of cholesterol, 7.0% by mass of gelatin, 29.8% by mass of mud, 0.5% by mass of carbon black, and 20 sheets. • Cut a shirt (manufactured by BVD) to a size of 3 cm × 3 cm. A shirt with a bath ratio of 20 times is used. The washing material subjected to the washing treatment was dehydrated for 1 minute, and then rinsed with 900 mL of 3°DH hard water at 25° C. for 3 minutes at 120 rpm and 25° C. (rinsing treatment). This rinsing treatment was repeated twice. A predetermined amount of softener was added for the second time in the rinsing treatment. The softener is a 0.21 mL "Soflan" (trade name, manufactured by Lion Corporation). After the rinsing-treated laundry was dehydrated for 1 minute, the cotton re-contamination determination cloth was sandwiched between the filter papers and dried by an iron (drying treatment). The washing treatment, the rinsing treatment, and the drying treatment described above were repeated three times (hereinafter referred to as washing treatment). The reflectance of the cotton re-contamination determination cloth before and after the washing treatment was measured using a reflectance meter (Spectrophotometer SE2000, manufactured by Nippon Denshoku Industries Co., Ltd.), the Z value was calculated, and the washing was subtracted from the Z value before the washing treatment. The value obtained by the processed Z value is ΔZ. The average value of ΔZ of the five pieces of cotton re-contamination determination cloth was classified into the following evaluation criteria, and the re-pollution prevention effect was evaluated. (Evaluation criteria) ○: ΔZ is less than 5 △: ΔZ is 5 or more and less than 9 ×: ΔZ is 9 or more

[Evaluation of Appearance Stability] 100 mL of liquid detergent for each product was collected in a transparent glass bottle (wide mouth standard bottle PS-No. 11), sealed with a lid, and the obtained one was used as a measurement test. kind. The appearance of the liquid temperature of the measurement sample was adjusted to 25 ° C in a thermostatic chamber, and the appearance after standing for 30 minutes (just after preparation) and the liquid temperature of the measurement sample were adjusted to 25 ° C. The appearance after standing for 24 hours was evaluated for appearance stability by the following criteria. Let △ and ○ be qualified. (Criteria for Judgment) ○: Any one after the preparation and after standing for 24 hours is transparent. △: It was transparent after the preparation, but it was slightly turbid after standing for 24 hours. ×: Any one after the preparation or after standing for 24 hours saw a clear turbidity or precipitation.
