Description

[Technical field]

[0001] The present invention is a floor space of 30 m 2 The present invention relates to an aromatic composition that can be used in the above indoor space and can diffuse a fragrance throughout the entire indoor space. [Background technology]

[0002] In recent years, various unpleasant odors such as body odor have been increasingly present in indoor spaces due to factors such as airtight housing and a Westernized (meat-eating) diet. In order to eliminate the discomfort caused by odors and create a comfortable indoor space, air freshener compositions containing fragrances are widely used.

[0003] In recent years, there has been an increase in spacious living rooms and dining kitchens to accommodate diversifying lifestyles and more comfortable living environments. However, conventional air fresheners are not designed for use in large indoor spaces, and therefore are not suitable for rooms with a floor area of ​​30 m2 or more. 2 When used in such a large indoor space, there is a drawback in that the fragrance composition can only be felt locally in the vicinity of where it is placed, and the fragrance cannot be diffused to every corner of the indoor space.

[0004] It has been reported that preparations containing a component that generates gas in the presence of water and a fragrance component promote the diffusion of the fragrance component into the air and provide an excellent fragrance effect even when used in a large indoor space. (See Patent Document 1.) However, the technology of Patent Document 1 has the drawback of having a short shelf life because it promotes the diffusion of aromatic components by foaming a component that generates gas in the presence of water.

Fragrance composition" above. EXAMPLES

[0035] The present invention will be described below with reference to examples, but the present invention is not limited to these examples.

[0036] Test Example 1 The aromatic compositions were prepared according to the compositions shown in Tables 1 and 2. The obtained aromatic compositions were used in a floor area of ​​9.72 m 2 (6 tatami mats, space volume 24.3m 3 ), floor space 33.12 m 2 (20 tatami mats, space volume 82.8m 3 ), 48.6m 2 (30 tatami mats, space volume 121.5 m 3 Specifically, 400 ml of the obtained aromatic composition was placed in a 450 ml container (opening area: about 7 cm 2 ), a volatilizing member (a nonwoven composite fiber material of polyethylene terephthalate and pulp; a structure in which a nonwoven sheet of 295 mm in length, 39 mm in width, and 6 mm in thickness is folded and overlapped starting from the center in the length direction) was inserted into the container, and with a part of the volatilizing member protruding outside the opening of the container, the container was placed in a corner of the room with the floor space and the door and window of the room were closed. One hour after placing the fragrance composition, 10 trained panelists entered the room in which the fragrance composition was placed and evaluated the fragrance intensity at the location furthest from the fragrance composition. Each panelist scored the fragrance with "0 points" indicating that almost no fragrance was detected, "5 points" indicating that a moderate and comfortable fragrance was detected, and "10 points" indicating that the fragrance was too strong and unpleasant, and the average of the evaluation scores of the 10 panelists was calculated and the average was classified according to the following criteria. <Criteria for classifying evaluation results> ◎: The average score is between 4 and 6 points ○(+): The average score is between 6 and 8 points ○(-): The average score is between 2 and 4 points ×(+): The average score is 8 or more points ×(-): The average score is less than 2 points

[0037] The results are shown in Tables 1 and 2. The fragrance composition containing 1.3% by weight of rose-based fragrance or peach-based fragrance and not containing javanol, α-ionone, α-damascone, or eugenol had a floor area of ​​9.72 m 2The room (6 tatami mats) had an excellent fragrance effect, but the floor area was 33.12 m 2 In indoor spaces of 20 tatami mats or more, the fragrance effect was insufficient (Comparative Examples 1 to 4). In addition, in the case of the fragrance composition not containing Javanol, α-ionone, α-damascone, or eugenol, even if the content of the rose-based fragrance or the peach-based fragrance was increased to 2.6% by weight or 3.9% by weight, the fragrance effect was insufficient in an indoor space of 33.12 m2 or more (Comparative Examples 1 to 4). 2 In contrast, no excellent fragrance effect was observed in an indoor space of 20 tatami mats or more (Comparative Examples 5 to 8). In contrast, the fragrance compositions containing javanol, α-ionone, α-damascone, or eugenol together with a rose-based or peach-based fragrance had a high fragrance effect in an indoor space of 33.12 m2 or more in floor space. 2 It was possible to provide an excellent aromatic effect to an indoor space of 20 tatami mats or more.
