R—O— [EO] _n —H (I)
(In the formula, R is a hydrocarbon group having 8 to 10 carbon atoms, EO is an ethyleneoxy group, and n is an integer of 0, 1, or 2.)

  Moreover, this invention relates to the washing | cleaning method of clothing which wash | cleans clothing, after immersing clothing in the washing | cleaning liquid obtained by mixing the cleaning composition for clothing of the said invention with water for 10 minutes or more.

Although it is not limited about the reason why the detergent composition for clothes of the present invention has an excellent sebum detergency, the present inventors consider as follows. The component (B) has properties that are higher in hydrophobicity than water and higher in hydrophilicity than sebum dirt. In addition, the component (B) has a higher affinity for sebum soil than for water. The component (B) adsorbs and permeates the sebum soil, thereby increasing the hydrophilicity of the sebum soil. Detergency is improved because the sebum soil having increased hydrophilicity is easily detached from the clothing. The component (A) is used as a cleaning component. In addition, the micelle formed by the component (A) in the cleaning liquid has a role of incorporating the component (B), which is highly hydrophobic and difficult to disperse in water, so that the component (B) is stably present in the cleaning liquid. When the number of carbon atoms of the hydrocarbon group of component (A) is the same as the number of carbon atoms of the hydrocarbon group of component (B), the hydrophobic mutual that occurs between the hydrocarbon groups of component (A) and component (B) The action becomes stronger. As a result, the component (B) is desorbed from the micelle formed by the component (A) and hardly adsorbs to sebum dirt. In the present invention, by making the carbon number of the hydrocarbon group of the component (B) smaller than the carbon number of the hydrocarbon group of the component (A), the hydrocarbon group of the component (A) and the component (B) It weakens hydrophobic interactions. As a result, the component (B) is detached from the micelle formed by the component (A) and is easily adsorbed to sebum dirt.
On the other hand, when the hydration ability of the hydrophilic group of the component (B) is too high, the component (B) is adsorbed to the sebum soil and hardly penetrates. As the hydrophilic group of the component (B), the effect of the present invention is enhanced by selecting a hydrophilic group in which 1 mol or 2 mol of an ethyleneoxy group is added to 1 mol of a hydroxyl group and a hydroxyl group.

ADVANTAGE OF THE INVENTION According to this invention, the washing | cleaning composition for clothing which has the outstanding cleaning power with respect to the sebum dirt adhering to clothing, and the washing | cleaning method of clothing using the same can be provided.
The garment cleaning composition of the present invention is suitable for a garment cleaning method involving immersion cleaning, and usually removes sebum stains that are hard to fall off and remain easily, for example, with an immersion time of about 30 minutes, which is a general immersion time. Can be removed from clothing. Furthermore, by washing the garment after immersion, the remaining sebum in the garment after washing can be reduced and a very high washing effect can be exhibited.

  In the present invention, clothing refers to textile products or fabric products used by people such as underwear, shirts, trousers, socks, towels, handkerchiefs, sheets, macula covers, bath mats, cloth shoes, etc. It shall refer to all the textile products provided.

Examples 1-14 and Comparative Examples 1-9
A powder detergent composition having the composition shown in Table 1 was prepared. The following cleaning power evaluation was performed using the obtained powder cleaning composition. The results are shown in Table 1. In addition, the numerical value of the composition in a table | surface is a compounding quantity (mass%). Moreover, in the comparative example, (A) / (B) mass ratio was shown by making (B ') component into (B) for convenience. Although the component (B ′) belongs to the component (E), the component (B ′) is indicated as the component (B ′) so that it can be easily compared as a comparative compound of the component (B).

(Evaluation of cleaning power)
2.4 g of the detergent composition was dissolved in ion exchange water to prepare a 600 mL aqueous solution. Thereafter, 1.5 mL of 400 ° DH hardness water (Ca ²⁺ / Mg ²⁺ = 8/2 [molar ratio]) prepared in advance using calcium chloride and magnesium chloride was added to the aqueous solution. The hardness was adjusted to 10 ° DH. An aqueous solution having a hardness of 10 ° DH was used as a model cleaning solution. The concentration of all surfactants in the model cleaning solution was 1000 ppm. Moreover, the 25 degreeC pH of the model washing | cleaning liquid was 10-11.

  Four collar model artificially contaminated cloths were put in 600 mL of the model washing solution, and immersed at 30 ° C. for 30 minutes. Then, this model washing | cleaning liquid and the collar model artificial contamination cloth were transferred to the tartometer, and it wash | cleaned at 30 degreeC for 3 minutes at 180 rpm / min. After washing, it was rinsed with tap water, dehydrated, and naturally dried overnight at room temperature of about 20 to 25 ° C., and the detergency was measured. Detergency measures the reflectance at 550 nm of the raw cloth before contamination and before and after cleaning with a self-recording colorimeter (manufactured by Shimadzu Corporation), and calculates the cleaning rate (%) by the following formula, and the average value of four sheets Was determined according to the following criteria.

  It is preferable that the value of the cleaning rate is high. In this evaluation, it can be determined that the cleaning rate is excellent if the cleaning rate is 75% or more.

<Production of artificially contaminated cloth>
