Using the obtained softening agent composition, the softening agent treatment was performed by the following method, and the wrinkle suppressing effect, the feeling of slimness and the softness were evaluated. The results are shown in Tables 4-6.
[0035]
<Method for preparing softener composition>
The component (d), the component (f) and the component (g) were dissolved in water and heated to 60 ° C. When the temperature reaches 60 ° C., the components (a), (b), (c) and (e) are added while stirring with a homomixer, and a predetermined amount is added with a 35% hydrochloric acid aqueous solution and a 48% sodium hydroxide aqueous solution. After adjusting to pH, the mixture was cooled to 30 ° C. with propeller stirring, the remaining components were added and mixed, and then cooled to room temperature.
[0036]
<Softener treatment method>
Put 2 kg of a commercially available white polo shirt (100% cotton) into a fully automatic washing machine (National NA-F60E), wash it with a commercially available weak alkaline detergent (Attack made by Kao Corporation), and then rinse the second time as shown in Tables 4-6. A softener treatment was performed using each softener composition (standard course, detergent concentration 0.0667% by weight, softener amount 10 mL, tap water 40 L used, water temperature 20 ° C.). Then, the clothes were hung on a hanger and dried naturally. Moreover, in the softening agent composition of Tables 4-6, the composition which silicone is not mix | blended separately was prepared separately, and was similarly processed into the commercially available white polo shirt (100% cotton), and it was set as control clothing.
[0037]
<Wrinkle suppression effect evaluation method>
Ten panelists (male in their 30s) visually observed the treated polo shirt and the polo shirt of the control clothing, compared one pair, and determined the average score by judging according to the following criteria. An average score of 0 or more and less than 1 was judged as ◎, 1 or more and less than 2 as ○, 2 or more and less than 3 as Δ, and 3 as x.
