The liquid detergent composition of the present invention (hereinafter sometimes simply referred to as a 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)
(In Formula (1), 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. , AO represents an alkyleneoxy group having 2 to 4 carbon atoms, n represents an average number of AO repeats 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 a straight chain or a branched chain.
R ¹ preferably has 10 to 20 carbon atoms, more preferably 10 to 18 carbon atoms. If the carbon number of R ¹ is not less than the above lower limit value, it is easier to increase the cleaning power of the liquid detergent, and if it is not more than the above upper limit value, precipitation or white turbidity is less likely to occur in the liquid detergent (that is, liquid stability). Excellent).

If n is not less than the above lower limit value, the surfactant is less likely to remain in the article to be washed when the article to be washed is washed with a liquid detergent and rinsed with water (that is, excellent in rinsing properties). . For this reason, the water absorption of a to-be-washed object can be raised more. When n is not more than the above upper limit, the hydrophobicity of the component (A) does not become too high, and the detergency can be further increased.
(1) In the formula, AO in (AO) _n may be one type alone or two or more types. When AO is 2 or more types, (AO) _n may be a random copolymer or a block copolymer.
(A) A component may be used individually by 1 type and may be used in combination of 2 or more type.

In the above formula (2), R ¹¹ represents a hydrocarbon group having 8 to 22 carbon atoms. If the number of carbon atoms is 8 or more, it is easy to obtain a sufficient cleaning effect against hydrophobic soil, and it becomes easier to increase the water absorption of synthetic garments and the like than before the washing treatment. If the carbon number is 22 or less, the liquid stability is hardly impaired. The carbon number of the hydrocarbon group of R ¹¹ is preferably 10 to 18 because the detergency is more easily improved.
R ¹¹ is preferably an alkyl group or an alkenyl group. These may be linear or branched. Examples of such an alkyl group or alkenyl group include alkyl groups or alkenyl groups derived from raw materials such as primary or secondary higher alcohols, higher fatty acids, higher fatty acid amides and the like.

In the above formula ^{(2), X} 2 represents O or COO. When X ² is O, R ¹² represents a hydrogen atom. That is, when X ² is O, the component (A1) is an alcohol alkoxylate.

s is a number from 13 to 30, more preferably from 13 to 20, and more preferably from 13 to 18.
If s is not less than the above lower limit value, the rinsing property does not become too low, the surfactant becomes difficult to remain in the article to be washed, and the water absorption is further increased. If s is not more than the above upper limit value, the hydrophilicity is not too high and the detergency is further increased.

The distribution of s in formula (2) varies depending on the reaction method in producing the component (A1). For example, when ethylene oxide or propylene oxide is added to a raw material using sodium hydroxide, potassium hydroxide or the like, which is a general alkali catalyst, the distribution of s becomes relatively wide. A specific alkoxylation catalyst such as magnesium oxide to which metal ions such as Al ³⁺ , Ga ³⁺ , In ³⁺ , Tl ³⁺ , Co ³⁺ , Sc ³⁺ , La ³⁺ , Mn ^{2+ and the} like described in JP-B-6-15038 is added. When ethylene oxide is added to the raw material, the distribution of s becomes relatively narrow. A relatively narrow distribution of s makes it easier to obtain a high cleaning effect.

Similar to (1), after washing, the polyester skin shirt was left in a constant temperature and humidity chamber at 25 ° C. and a humidity of 65% RH for 2 weeks. About this test garment and the polyester skin shirt before performing the washing treatment, the operation of 10 professional panelists to wear through the head was performed, and each test garment was scored based on the following evaluation criteria. An average value of 10 panelists was evaluated based on the following criteria, and a C evaluation or higher (an average value of 2.5 or higher) was regarded as acceptable.
In addition, this touch evaluation was implemented in said constant temperature and humidity chamber.
[Evaluation criteria]
1 point: The same comfort as the garment before the washing treatment, or the garment before the washing treatment is more comfortable.
2 points: It is slightly more comfortable than the clothes before the laundry treatment.
3 points: It is more comfortable than the clothes before the laundry treatment.
4 points: It is much more comfortable than the clothes before the laundry treatment.
5 points: Very comfortable to wear than the clothes before the laundry treatment.
[Criteria]
A: The average value is 4.5 points or more, B: The average value is 3.5 points or more and less than 4.5 points, C: The average value is 2.5 points or more and less than 3.5 points, D: The average value is 2. Less than 5 points.

(Water absorption evaluation)
Ten test pieces obtained by the above-described washing treatment method were left to dry in a constant temperature and humidity chamber at 25 ° C. and a humidity of 65% RH for one day.
The temperature was adjusted to 25 ° C. to store 1 L of tap water in a 1 L beaker. One test piece was floated on the surface of the water, and the time until the test piece soaked in water or settled on the bottom of the beaker was measured. The shorter the time, the higher the water absorption. The average time of the time for 10 test pieces to sink in water was obtained and evaluated according to the following criteria. It should be noted that the average time for the 10 test pieces before being washed to sink in water was 70 seconds. Therefore, C evaluation or higher was determined as acceptable in the following criteria.
[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 compositions shown in Tables 1 to 4 were placed in a cylindrical glass bottle, the lid was closed, and the liquid detergent composition was stored in a 5 ° C constant temperature bath and a 50 ° C constant temperature bath for 1 month. The appearance after storage was visually observed, and the liquid stability was evaluated based on the following evaluation criteria.
[Evaluation criteria]
A: Uniform and no separation.
B: Uniform but slightly yellowing is observed.
C: Separation / precipitation is observed.

Tables 1 to 4 show the evaluation results of comfort, water absorption and liquid stability of the liquid detergents in each example.
In the table, “B / C” represents the mass ratio (B) / (C) in the liquid detergent. “A + B” represents the total amount (mass%) of the component (A) and the component (B) in the 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 with those before the washing treatment.
In Comparative Examples 1 to 11 which do not contain any of the components (A) to (C), either the touch evaluation or the water absorption evaluation was evaluated D.
From the above results, it was confirmed that by using the liquid detergent composition of the present invention, it is possible to increase the comfort and water absorption of the synthetic garment and the like as compared with those before the washing treatment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS By subjecting a synthetic garment to a washing treatment using the liquid detergent composition of the present invention, it is useful because it can improve the comfort and water absorption of the synthetic garment that is the object to be washed.
