[Example]

[0066] <Production example> The sodium di-(2-propylheptyl)sulfosuccinate listed in Table 1 was prepared as follows. A 2 L four-neck flask equipped with a stirrer, heating system, distillation column, and nitrogen / vacuum connection was charged with 176.5 g (1.8 mol) of maleic anhydride, 626.6 g (4.0 mol) of 2-propylheptanol, and 2.5 g (0.013 mol) of p-toluenesulfonic acid monohydrate. After nitrogen purge, the mixture was reacted at 100-130 °C with nitrogen bubbling while dehydrating until the acid value decreased to the p-toluenesulfonic acid equivalent. The catalyst was then adsorbed using Kyoward 500SH (Kyowa Chemical Industry Co., Ltd.) at 1% by mass relative to the total content of the reaction vessel. After removing the adsorbent, the excess alcohol was removed by topping to obtain the maleic acid diester.

[0067] Next, 278 g (0.70 mol) of the maleic acid diester obtained above, 73 g (0.38 mol) of sodium disulfite, and 48 g (2.7 mol) of ion-exchanged water were charged into a 1-L glass reaction vessel and reacted at 115°C using a polar alcoholic solvent by a known method until the double bond derived from the maleic acid diester disappeared by NMR. The mixture was cooled to 50-65°C, and the remaining sodium hydrogen sulfite was oxidized with 30% hydrogen peroxide. The pH was then adjusted to 5 with 10% NaOH. The solvent and sodium sulfate were removed by distillation under reduced pressure, reprecipitation, and separation, yielding sodium di-(2-propylheptyl)sulfosuccinate. The following components were used in the production of sodium di-(2-propylheptyl)sulfosuccinate.

A treatment liquid was prepared using this transpiration enhancer, and the transpiration enhancer was evaluated according to the following evaluation method 1. <Preparation method 1 of the transpiration accelerator> A total of 10 g of component (A) and component (B) was mixed with 190 g of ion-exchanged water so that the mass ratio of component (A) to component (B) was the ratio shown in Table 1, to prepare the transpiration enhancer of each example. Specifically, component (A) was dispersed in 190 g of 80°C ion-exchanged water for 1 hour, and then, when component (B) was included, component (B) was added and stirred for 30 minutes, cooled to room temperature (20°C), and then an appropriate amount of ion-exchanged water (equivalent to volatilized water) was added so that the mass of the mixture became 200 g, thereby preparing the evaporation enhancers of Examples 1-1 to 1-26. When component (B) was hexane or heptane, the mixture was cooled to room temperature before adding component (B).

[0070] <Evaluation method for transpiration 1> 1) Pretreatment of evaluation towels 1 The towels used for evaluation were previously subjected to the following treatment to remove adhesive and impurities. Using a fully automatic washing machine (Panasonic, model number: NA-F60PB3), 24 commercially available cotton towels (TW220, Takei Towel Co., Ltd., white, 100% cotton) were washed three times using 52.22 g of a 10% diluted solution of a nonionic surfactant (Emulgen 108, Kao Corporation) as detergent and Wakayama City tap water (tap water has a hardness of 4°DH; the same applies below). The washing cycle (50 L of water, 10 minutes of washing, two rinses, and 9 minutes of spin-drying) was then repeated twice using water only. The towels were then left to dry naturally at room temperature (25°C) for 24 hours.

[0071] 2) Towel disposal method 1 A predetermined amount of ion-exchanged water (bath ratio 30 L / kg towel) was added to a mini-mini washing machine (National, Model No.: NA-35), and a calcium chloride solution (equivalent to 4000°C dH) was added to achieve the hardness shown in Table 1. While stirring, 8.4 g of the evaporation enhancer (solution) (total concentration of components (A) and (B) 5% by mass) shown in Table 1 was added and stirred for 1 minute to prepare a treatment solution. Two cotton towels (total weight: approximately 140 g) pretreated in the above step 1) were then added and treated for 5 minutes with stirring. The total amount of components (A) and (B) used for this treatment was the treatment concentration (% owf) shown in Table 1, based on two cotton towels. The cotton towels were then dehydrated for 3 minutes in the spin tub of a twin-tub washing machine (TOSHIBA, Model No.: VH-52G(H)) and dried for 24 hours in a constant temperature and humidity chamber at 23°C and 40% RH. The moisture content of the towels after 4 hours of drying (% by mass) and the time (hr) until the moisture content of the towels reached 15% by mass are shown in Table 1. In Comparative Example 1-1, two cotton towels were treated in the same manner as in the Examples, using water with the hardness shown in Table 1, without using any transpiration promoter. The moisture content of the towels was calculated based on the following formula. The shorter the time until the moisture content of the towels reached 15% by mass, the more transpiration has been promoted. Towel moisture content [mass %] = [(mass of moist towel [g] / initial towel mass [g]) - 1] × 100 (1) Initial towel mass: Mass of dried towel after pretreatment Wet towel mass: Mass of towel after drying for a specified drying time

[0072] [Table 1]

[0073] In Table 1, Examples 1-12 and 1-13 have the same time as Example 1-1, which does not contain (B), for the towel moisture content to reach 15% by mass. However, even when the amount of component (A) is reduced by 20%, the time is the same as that for Example 1-1, and therefore it can be evaluated that the evaporation-promoting effect of component (A) is promoted.

[0074] Example 2 <Examples 2-1 to 2-3> An transpiration enhancer was prepared using the components (A) and (B) listed in Table 2 according to the following preparation method 2. A treatment liquid was prepared using this transpiration enhancer, and the transpiration enhancer was evaluated according to the following evaluation method 2. <Preparation method 2 of the transpiration accelerator> The transpiration promoter of each example was prepared by mixing the components (A) and (B) in advance so that the mass ratio of the components (A) and (B) was the ratio shown in Table 2 and the total amount of the components (A) and (B) was 10 g, and then adding ion-exchanged water to bring the mass of the mixture to 200 g. Specifically, first, a liquid containing component (A) (a liquid containing 63 mass% of component (A), 17 mass% of propylene glycol, and the remainder water) was mixed with component (B) at 80°C so that the mass ratio of component (A) to component (B) was the ratio shown in Table 2 and the total amount of component (A) and component (B) was 10 g. This mixture was further mixed with ion-exchanged water at 80°C and stirred for 1 hour, cooled to room temperature (20°C), and then an appropriate amount of ion-exchanged water was added so that the mass of the mixture was 200 g, thereby preparing the transpiration enhancers of Examples 2-1 to 2-3.

[0075] <Evaluation method for transpiration 2> 1) Pretreatment of evaluation towels 2 Twenty-four commercially available cotton towels (TW220 manufactured by Takei Towel Co., Ltd., white, 100% by mass cotton) were subjected to pretreatment in the same manner as in pretreatment 1 for the evaluation towels. 2) Towel disposal method 2 A predetermined amount of ion-exchanged water (bath ratio 30 L / kg-towel) was placed in a mini-mini washing machine (National, model number: NA-35), and a calcium chloride aqueous solution (equivalent to 4000°dH) was added to achieve the hardness shown in Table 2. While stirring, 8.4 g of the transpiration enhancer (solution) (total concentration of components (A) and (B) 5% by mass) shown in Table 2 was added and stirred for 1 minute to prepare a treatment solution. Two cotton towels (total weight: approximately 140 g) pretreated in step 1) above were then added and treated for 5 minutes with stirring. In this treatment, the total amount of components (A) and (B) used was the treatment concentration (% owf) shown in Table 2, based on two cotton towels. Next, the cotton towels were dehydrated for 3 minutes in the spin tub of a twin-tub washing machine (Hitachi, model PS-55AS2) and then dried for 24 hours in a constant temperature and humidity chamber at 23°C and 40% RH. Table 2 shows the moisture content [mass%] of the towels after 4 hours of drying and the time [hr] until the moisture content of the towels reached 15% by mass. In Comparative Example 2-1, two cotton towels were treated in the same manner as in Example 2-1, but without using any transpiration enhancer and using water with the hardness shown in Table 2. The moisture content of the towels was calculated based on formula (1) for towel moisture content described in Towel Treatment Method 1 above. It was also confirmed separately that propylene glycol did not function as component (B) under the treatment conditions of this example.
