(Liquid detergent composition)
The liquid detergent composition of the present invention (hereinafter sometimes referred to simply as liquid detergent) is a composition containing the components (A) to (C).

<(A) component>
The component (A) is a nonionic surfactant represented by the following general formula (1).
R ¹ -X ^1- (AO) _n -R ² (1)
(Wherein, R ¹ represents a hydrocarbon group having 8 to 22 carbon atoms, X ¹ represents O or COO, and R ² represents a hydrocarbon group having 1 to 2 carbon atoms or a hydrogen atom) And AO represent an alkyleneoxy group having 2 to 4 carbon atoms, n represents an average number of repetition of AO, and is a number of 13 or more, provided that when X ¹ is O, AO represents an ethyleneoxy group .)

In the formula (1), R ¹ is a hydrocarbon group having 8 to 22 carbon atoms.
R ¹ may be a saturated hydrocarbon group or an unsaturated hydrocarbon group.
R ¹ may be linear or branched.
10-20 are preferable and, as for carbon number of R < ¹ >, 10-18 are more preferable. If the carbon number of R ¹ is more than the above lower limit value, the detergency of the liquid detergent is easily enhanced, and if it is less than the above upper limit value, precipitation and white turbidity hardly occur in the liquid detergent (ie, liquid stability Excellent).
As R ¹ , a linear or branched alkyl group having 8 to 22 carbon atoms or a linear or branched alkenyl group having 8 to 22 carbon atoms is preferable.
In formula (1), R ² is a hydrocarbon group having 1 to 2 carbon atoms or a hydrogen atom.

If n is equal to or more than the above lower limit, the surfactant is less likely to remain on the object to be washed when the object to be washed is washed using a liquid detergent and rinsed with water (that is, excellent in rinse performance) . For this reason, the water absorbency of a to-be-washed thing can be heightened more. If n is below the said upper limit, the hydrophobicity of (A) component will not become high too much, and the cleaning power can be heightened more.
In the formula (1), AO in (AO) _n may be used alone or in combination of two or more. When AO is 2 or more types, (AO) _n may be a random copolymer or a block copolymer.
As the component (A), one type may be used alone, or two or more types may be used in combination.

In the formula ^{(2), R 11} represents a hydrocarbon group having 8 to 22 carbon atoms. When the number of carbon atoms is 8 or more, the cleaning effect on hydrophobic stains is easily obtained, and the water absorbency of the synthetic clothing and the like can be easily increased as compared to before the washing treatment. If the carbon number is 22 or less, the solution stability is also less likely to be impaired.

If s is not less than the above lower limit value, the rinse property is not too low, the surfactant hardly remains in the to-be-washed matter, and the water absorbability is further enhanced. If s is less than or equal to the above upper limit, the hydrophilicity is not too high and the detergency is further enhanced.

The distribution of s in the formula (2) varies depending on the reaction method in producing the component (A1). For example, when ethylene oxide or propylene oxide is added to the raw material using sodium hydroxide or potassium hydroxide which is a common alkali catalyst, the distribution of s becomes relatively wide. A specific alkoxylation catalyst such as magnesium oxide to which a metal ion such as Al ³⁺ , Ga ³⁺ , In ³⁺ , Tl ³⁺ , Co ³⁺ , Sc ³⁺ , La ³⁺ or Mn ²⁺ described in Japanese Patent Publication No. 6-15038 has been added When ethylene oxide is added to the raw material to be used, the distribution of s becomes relatively narrow. The relatively narrow distribution of s facilitates obtaining a high cleaning effect.

The durability of the comfort was judged based on whether or not the comforting comfort lasted for two weeks. After washing, as in (1), the polyester skin shirt was left in a constant temperature and humidity room at 25 ° C. and a humidity of 65% RH for 2 weeks. With respect to the test clothes and the polyester skin shirt before being subjected to the laundry treatment, 10 expert panelists performed an operation to wear them through their heads, and each test clothes was scored based on the following evaluation criteria. The average value of 10 panelists was evaluated based on the following judgment criteria, and the evaluation of C or higher (the average value of which was 2.5 points or higher) was regarded as passing.
In addition, this touch evaluation was implemented in said constant temperature and humidity chamber.
[Evaluation criteria]
1 point: The same comfort as the clothes before the laundry treatment, or the wear before the laundry treatment is more comfortable.
2 points: It is a little more comfortable to wear than the clothes before the laundry treatment.
3 points: It is a more comfortable fit than the clothes before the laundry treatment.
4 points: It is much more comfortable to wear than the clothes before the laundry treatment.
5 points: It is much more comfortable to wear than the clothes before the laundry treatment.
Judgment criteria
A: Average value is 4.5 points or more, B: Average value is 3.5 points or more and less than 4.5 points, C: Average value is 2.5 points or more and less than 3.5 points, D: Average value is 2. Less than 5 points.

(Water absorption evaluation)
Ten test pieces obtained by the above-mentioned laundry treatment method were left in a constant temperature and humidity room at 25 ° C. and a humidity of 65% RH for 1 day to be dried.
The temperature was adjusted to 25 ° C. by adding 1 L of tap water to a 1 L beaker. One of the test pieces was floated on the water surface, and the time taken for water to soak in the test piece or sink to the bottom of the beaker was measured. The shorter the time, the higher the water absorbability. The average time of 10 pieces of test pieces sinking in water was determined and evaluated in accordance with the following judgment criteria. In addition, the average time for the time for which the 10 test pieces before being subjected to the washing treatment sink in water was 70 seconds. Therefore, in the following judgment criteria, C evaluation or more was taken as passing.
Judgment 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 to 4 was taken in a cylindrical glass bottle, the lid was closed, and it was stored for 1 month in a thermostat of 5 ° C and a thermostat of 50 ° C. The appearance after storage was visually observed, and the liquid stability was evaluated based on the following evaluation criteria, and those with A and B evaluations were regarded as passing.
[Evaluation criteria]
A: uniform and not separated.
B: Uniform but slightly yellowish
C: Separation / precipitation is observed.

Tables 1 to 4 show the evaluation results of the comfort, water absorbency and liquid stability of the liquid detergents of the respective examples.
In addition, "B / C" in a table | surface represents mass ratio (B) / (C) in a liquid detergent. "A + B" represents the total amount (mass%) of (A) component and (B) component in a liquid detergent.

As shown in Tables 1 to 4, in Examples 1 to 34, the touch evaluation and the water absorption evaluation were improved as compared to those before the laundry treatment.
In Comparative Examples 1 to 11 which do not contain any of the components (A) to (C), one of the touch evaluation and the water absorption evaluation was the evaluation D.
From the above results, it has been confirmed that, by using the liquid detergent composition of the present invention, it is possible to enhance the comfort and the water absorbability of the synthetic clothing and the like more than before the laundry treatment.

  By subjecting the liquid detergent composition of the present invention to a washing treatment on a synthetic fiber garment, it is possible to enhance the dry comfort and the water absorbability of the synthetic fiber garment to be washed, which is useful.
