<(a) component>
[Synthesis Example 1: Synthesis of (a-1)]
1.7 g of diisobutylene-maleic anhydride copolymer (Demol EP, solid content 25%, Kao Co., Ltd.) was neutralized with hydrochloric acid and further diluted with ion-exchanged water to give solid content 3% and pH 4.3. An aqueous solution of Next, 36 g of the fragrance composition shown in Table 1 was added to 100 g of the aqueous diisobutylene-maleic anhydride copolymer solution, emulsified using a homomixer, and the temperature was raised to 50°C. Next, an aqueous solution obtained by mixing 12 g of a partially methylolated melamine resin (trade name Cymel385, solid content 80%, manufactured by Cytec Industries Inc) and 35 g of ion-exchanged water was added dropwise. This was kept at 50° C. for 2 hours, further kept at 70° C. for 1 hour, and further kept at 80° C. for 3 hours to complete the encapsulation. Then, by cooling, a microcapsule slurry having an average particle size of 7 μm and an effective content of 30% by mass was obtained. The effective component of this microcapsule slurry was a fragrance microcapsule, which was designated as (a-1). The composition was used in the form of microcapsule slurry.

(D-2): Propylene glycol (CLogP=-1.1)

〔water〕
Deionized water

〔container〕
・Container 1: SFF dispenser S (REC Co., Ltd., opening area of discharge port=16 mm ² )
-Container 2 (comparative container): Ultra Attack Neo main body bottle (the opening area of the discharge port of Kao Corporation = 154 mm ² ).

<Preparation of liquid perfume composition for clothing>
A Teflon (registered trademark) stirrer piece having a length of 5 cm was placed in a glass beaker having a capacity of 200 mL to measure the mass. A necessary amount of ion-exchanged water (25° C.) is added to the liquid perfume composition for clothing to a final mass of 200 g, and the components (b) and (c) are required while stirring with a magnetic stirrer. Then, the component (d) was added. Next, the component (a) or the component (a′) was added dropwise while stirring as it was, and the upper surface of the beaker was sealed with Saran Wrap (registered trademark). Then, the mixture was stirred for 30 minutes. Next, remove the saran wrap, measure the weight of the beaker containing the liquid flavoring agent for clothing again, add ion-exchanged water so that the finished mass is 200 g, and seal again with new Saran wrap (registered trademark). After stirring for 1 minute, a liquid perfume composition for clothing was obtained.

<Preparation of liquid perfume products for clothing>
The container 1 or the container 2 was filled with 150 g of the above liquid perfume composition for clothing to obtain a liquid perfume product for clothing.

The following items were evaluated using the obtained liquid perfume product for clothing. The results are shown in Table 2.

<Table 2: Tests of Example 1 and Comparative Examples 1 and 2>
Example 1 is a liquid perfume product for clothing in which a container 1 is filled with the liquid perfume composition for clothing (composition 1) described in Table 2, and Comparative Example 1 is the clothing described in Table 2. A liquid perfume composition for clothing, wherein the container 2 (comparative container) is filled with the liquid perfume composition for composition (composition 1), and Comparative Example 2 is the liquid perfume composition for clothing described in Table 2. It is a liquid perfume product for clothing in which (Comparative composition 1) is filled in a container 1. In Example 1 or Comparative Example 2, the method of pushing the pump was changed, and the time for discharging 10 mL of the content into the 50 mL glass beaker was changed to 5 seconds, 10 seconds, and 20 seconds. In Comparative Example 1, the operation of discharging from the bottle into a 50 mL glass beaker was performed. Based on the strength of the scent of a scent from a glass beaker containing the contents discharged in 10 mL for 10 seconds, the strength of the fragrance when the time for discharging 10 mL is set to 5 seconds or 20 seconds An evaluator skilled in evaluation evaluated the intensity of the scent. The results are shown in Table 2.

In Example 1 using the perfume microcapsule as the component (a) and the container 1 having the opening area of the discharge port within the range of the present invention, the intensity of the scent of the scent from the discharge product in which 10 mL of the content was discharged in 10 seconds was measured. When the standard is set to 1, the scent of the discharged product discharged from the product with 10 mL of contents in 5 seconds is stronger than the standard 1, and the scent from the discharged product of 10 mL of content discharged from the product in 20 seconds is from the standard 1. Also smelled weakly. The user who carried out Example 1 was able to enjoy scents of various strengths by changing the usage of the liquid perfume product for clothing of the present invention.
On the other hand, in Comparative Example 1 in which the container 2 having the opening area of the discharge port which is outside the scope of the present invention was used in place of the container 1 in Example 1 described above, the tilting direction of the container 2 was changed to obtain 10 mL of the content. Even if the usage is changed by changing the time for discharging the product, the intensity of the scent from the product discharged from the product is the same as the standard 2, and the user could not enjoy various scents. ..
Further, in Comparative Example 2 in which the same test as in Example 1 was performed except that the perfume composition was used in the non-capsule form in place of the perfume capsule in Example 1, the product was discharged from the product even when the usage of the product was changed. The intensity of the scent from the discharged product was the same, and the user could not enjoy various scents.

<Table 3: Tests of Examples 2 to 4>
The liquid perfume product for clothing in which the composition 1, the composition 2 or the composition 3 is filled in the container 1 is stored in a thermostatic chamber at 50° C. for 72 hours, and then left in a room at 25° C. for 24 hours. An evaluator skilled in the evaluation of fragrance intensity was used to perform the following Evaluation 1 and Evaluation 2 to evaluate the difference in fragrance intensity.
Evaluation 1: Strength of scent of scent from discharge of 10 mL of content in product in 10 seconds Evaluation 2: Strength of scent of scent of discharge of 10 mL of content in product in 1 second
