The "appropriate amount" which shows content of a pH adjuster shows the total amount (0.01-1 mass %) of the pH adjuster (sulfuric acid or sodium hydroxide) added in order to make pH (25 degreeC) of a liquid detergent into the pH value in a table|surface.

"Balance" which shows content of purified water means the remainder added so that the compounding quantity (mass %) of the sum total of all compounding components contained in a liquid detergent may become 100 mass %. "B/C ratio" of Comparative Examples 5 and 6 shows mass ratio of (B') component with respect to (C)component in a table|surface.

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

[Evaluation of the deodorization effect (1)]

About 100 g of cotton towels used at home for 1 week, and about 700 g of cotton shirts worn by men in their 20s and 30s per day (hereinafter referred to as “clothes” together with the cotton towels and cotton shirts), a fully automatic electric washing machine (JW-Z23A manufactured by Haier). Subsequently, 10 ml of the liquid detergent of each example was put into the washing machine, and washing, rinsing, and dehydration were performed in the standard course of the washing machine to wash the clothes. The clothes after washing were dried overnight. Regarding "unpleasant odor" of clothes after drying, 5 panelists, both male and female, scored according to the following six-step judgment criteria. The average value of the scoring results of 5 people was classified according to the following evaluation criteria, and the deodorizing effect (1) on clothes was evaluated. (triangle|delta), (circle), and (double-circle) were made into pass.

(based on judgment)

0 points: Odorless.

1 point|piece: A barely perceptible smell.

2 points|pieces: The smell which can recognize what kind of smell.

3 points|pieces: An odor that can be sensed comfortably.

4 points|pieces: strong odor.

5 points|pieces: A strong odor.

(Evaluation standard)

(double-circle) : 0 points or more and less than 1.5 points|pieces.

○: 1.5 points or more and less than 2.5 points.

(triangle|delta): 2.5 points or more and less than 3 points|pieces.

x: 3 points or more and 5 points or less.

[Deodorization effect (2): Deodorization evaluation of ammonia smell]

5 ml of a 0.1 N aqueous ammonia solution was applied to the clothes of [Evaluation of the deodorization effect (1)] and left to stand for 1 hour. Subsequently, a washing solution in which 10 ml of the liquid detergent of each example was dispersed in 5 L of tap water was prepared, and the clothes were immersed in this washing solution and left to stand for 2 hours. Thereafter, clothes were taken out of the washing solution, put into a fully automatic electric washing machine (JW-Z23A manufactured by Haier), and dehydrated. The "ammonia smell" of the clothes after dehydration was scored and classified in the same manner as [Evaluation of the deodorizing effect (1)] by 5 panelists, both men and women, and the deodorizing effect (2) of the ammonia smell was evaluated. (triangle|delta), (circle), and (double-circle) were made into pass.

[Evaluation of recontamination prevention properties]

0.3 ml of the liquid detergent of each case was disperse|distributed to 900 ml (25 degreeC) of 3 degreeDH hard water, and it was set as the washing|cleaning liquid. The washing liquid and the following object were placed in a Terg-o-tometer (manufactured by UNITED STATES TESTING), and the object was washed at 120 rpm and 25°C for 10 minutes (washing treatment).

(Things to be washed)

· Cotton material contamination determination cloth: Cotton Meriyasu (manufactured by Tanigashira Shopping Co., Ltd.) 5 × 5 cm … Chapter 5.

Wet artificial soiled cloth: manufactured by the Laundry Science Association (contaminating ingredients: oleic acid 28.3%, triolein 15.6% by mass, cholesterol oleate 12.2% by mass, liquid paraffin 2.5% by mass, squalene 2.5% by mass, cholesterol 1.6% by mass, gelatin 7.0 mass %, mud 29.8 mass %, carbon black 0.5 mass %)... Chapter 20. ·

The undershirt (manufactured by BVD) was cut to about 3 cm x 3 cm. I used an undershirt that doubled the yokbi (浴比).

After dehydrating the object to be washed for 1 minute, it was rinsed with 900 ml of 3° DH hard water at 25° C. at 120 rpm and 25° C. for 3 minutes (rinsing treatment). This rinsing treatment was repeated twice. A predetermined amount of a softening agent was added to the second time of the rinsing treatment. As the softening agent, 0.21 ml of "Sophran of fragrance and deodorant" (trade name, manufactured by Lion Corporation) was used. After the object to be washed after rinsing was dehydrated for 1 minute, a cotton ash contamination determination cloth was placed on a filter paper and dried with an iron (drying treatment).

The washing treatment, rinsing treatment, and drying treatment described above were repeated 3 times (above, washing treatment). Using a reflectometer (spectral color difference meter SE2000, manufactured by Nippon Denshoku Kogyo Co., Ltd.), the reflectance of the face material contamination determination cloth before and after the washing treatment is measured to calculate the Z value, and the Z value after the washing treatment is obtained from the Z value before the washing treatment. ΔZ, which is a value obtained by subtracting The average value of ΔZ of the 5 face material contamination determination cloths was classified according to the following evaluation criteria, and the recontamination prevention effect was evaluated.

(Evaluation standard)

○: ΔZ is less than 5

△: △Z is 5 or more and less than 9

×: ΔZ is 9 or more

[Evaluation of appearance stability]

100 ml of the liquid detergent for textile products of each example was collected in a transparent glass bottle (wide-sphere standard bottle PS-No. 11), and the product was sealed with a lid as a measurement sample. The external appearance after adjusting the temperature of the liquid of the measurement sample to 25° C. in a thermostat and standing still for 30 minutes (immediately after mixing), and after adjusting the temperature of the liquid of the measurement sample to 25° C. and standing still for 24 hours, were visually observed. observation, and the appearance stability was evaluated according to the following criteria. (triangle|delta) and (circle) were made into pass.

(based on judgment)

(circle): Both immediately after mixing|blending and after standing still for 24 hours are transparent.

(triangle|delta): It is transparent immediately after mixing|blending, but slightly cloudy after standing still for 24 hours is seen.

x: Clear turbidity or precipitation is seen either immediately after mixing or after standing for 24 hours.

[Table 1]

[Table 2]

[Table 3]

From the result shown in Tables 1-3, the liquid detergent of Examples 1-24 to which this invention was applied has confirmed that it was excellent in a deodorizing effect, recontamination prevention property, and external appearance stability.

On the other hand, the deodorizing effect was not enough for the liquid detergent (comparative example 1) which does not contain (A) component.

(C) The liquid detergent (comparative example 2) which does not contain a component did not have enough recontamination prevention property.

As for the liquid detergent (comparative example 4) whose pH exceeded the range of this invention, although the deodorizing effect (1) was ○, the deodorizing effect (2) was x, and the deodorizing effect with respect to an ammonia smell was not enough.

(B) The liquid detergent (comparative example 3) which does not contain a component, and the liquid detergent (comparative examples 5 and 6) using (B') component instead of (B) component were inferior in external appearance stability. For this reason, evaluation of the deodorizing effect and recontamination prevention property was not performed.

From the above results, it was confirmed that the liquid detergent to which the present invention is applied is excellent in deodorizing effect, recontamination prevention property, and appearance stability.
