<(A) component>

(A) A component is a nonionic surfactant represented by the following general formula (1).

R ¹ -X ¹ -(AO) _n -R ² ... (One)

(In formula (1), R ¹ represents a hydrocarbon group having 8 to 22 carbon atoms, X ¹ represents O or COO, R ² represents a hydrocarbon group having 1 to 2 carbon atoms or a hydrogen atom, and AO represents 2 to 4 carbon atoms. represents the number of alkyleneoxy groups. In addition, n represents the average number of repetitions of AO and is a number greater than or equal to 13. However, when X ¹ is O, AO represents an ethyleneoxy group)

(1) In formula, R< ¹ > is a C8-C22 hydrocarbon group.

R ¹ may be a saturated hydrocarbon group or an unsaturated hydrocarbon group.

R ¹ may be linear or branched.

10-20 pieces are preferable and, as for carbon number of R< ¹ >, 10-18 pieces are more preferable. It becomes it easy to raise the cleaning power of a liquid detergent more easily that carbon number of R< ¹ > is more than the said lower limit, and it becomes difficult to produce a deposit and cloudiness in a liquid detergent as it is below the said upper limit (that is, it is excellent in liquid stability).

As R< ¹ >, a C8-C22 linear or branched alkyl group or a C8-C22 linear or branched alkenyl group is preferable.

About this test garment and the polyester undershirt before the washing process, 10 professional panelists performed the operation|movement of putting their heads through, and scoring was performed based on the following evaluation criteria about each test garment. The average value of 10 panelists was evaluated based on the following criteria, and C evaluation or more (things with an average value of 2.5 points or more) was set as the pass.

In addition, this tactile evaluation was implemented in said constant temperature and humidity chamber.

[Evaluation standard]

1 point|piece: The wearing comfort equivalent to the clothes before washing processing, or the clothes before washing processing is a comfortable wearing feeling.

2 points|pieces: It is a feeling of wearing slightly more comfortable than the clothes before a washing process.

3 points|pieces: It is a feeling of wearing more comfortable than the clothes before a washing process.

4 points|pieces: The wearing comfort is considerably more comfortable than the clothes before a washing process.

5 points|pieces: It is very comfortable to wear compared to the clothes before a washing process.

[Criteria]

A: The average value is 4.5 points or more, B: The average value is 3.5 or more and less than 4.5 points, C: The average value is 2.5 or more and less than 3.5 points, D: The average value is less than 2.5 points.

(Absorbency evaluation)

10 test pieces obtained by the above-mentioned washing treatment method were left to stand in a constant temperature and humidity room at 25°C and a humidity of 65% RH for 1 day to be dried.

1L of tap water was placed in a 1L beaker, and the temperature was adjusted to 25°C. One said test piece was made to float on the water surface, and the time until water permeated into a test piece and immersed in the bottom of a beaker was measured. It shows that absorptivity is so high that time is short. The average time of the time that ten test pieces were immersed in water was calculated|required, and it evaluated according to the following criteria. In addition, the average time of the time for 10 test pieces to be immersed in water before performing a washing process was 70 second. Therefore, in the following judgment criteria, C evaluation or more was made into the pass.

[Criteria]

A: Average time is less than 30 seconds, B: Average time is 30 seconds or more and less than 45 seconds, C: Average time is 45 seconds or more and less than 1 minute, D: Average time is 1 minute or more.

(liquid stability evaluation)

The liquid detergent composition shown in Tables 1-4 was taken in the cylindrical glass bottle, the lid was closed, and it preserve|saved for 1 month in a 5 degreeC thermostat and a 50 degreeC thermostat. The appearance after storage was visually observed, liquid stability was evaluated based on the following evaluation criteria, and the thing of A and B evaluation was set as the pass.

[Evaluation standard]

A: It is uniform and there is no separation.

B: It is uniform, but slightly yellowing is seen.

C: Separation and precipitation are seen.

The evaluation result of the wearing feeling of the liquid detergent of each example, water absorption, and liquid stability is shown to Tables 1-4.

In addition, "B/C" in a table|surface shows the mass ratio (B)/(C) in a liquid detergent. "A+B" shows the total amount (mass %) of (A)component in a liquid detergent, and (B)component.

As shown in Tables 1-4, in Examples 1-34, the tactile evaluation and water absorption evaluation were improving compared with before the washing process.

In Comparative Examples 1 to 11, which did not contain any of the components (A) to (C), either of the tactile evaluation and the water absorption evaluation was evaluation D.

It was confirmed by using the liquid detergent composition of this invention that comfortable wearing comfort and water absorbency, such as chemical fiber clothing, can be improved rather than before washing processing from the above result.

(Industrial Applicability)

It is useful because the comfortable wearing feeling and water absorption of the chemical fiber clothing which is a to-be-washed object can be improved by performing a washing process to chemical fiber clothes using the liquid detergent composition of this invention.
