[0056] Although the amount of mosquito and tick repellent contained in each hygiene product varies depending on the user (human, pet, etc.) of the hygiene product, the duration of use, etc., the amount of mosquito and tick repellent contained in each hygiene product is preferably 1 mg or more, more preferably 5 mg or more, and even more preferably 10 mg or more, and the amount of mosquito and tick repellent contained in each hygiene product is preferably 100 mg or less, more preferably 70 mg or less, and even more preferably 40 mg or less, thereby providing the hygiene product with excellent mosquito and tick repellency.

[0057] In the sanitary product according to the present disclosure and the use according to the present disclosure, the sanitary product may have an inner surface that contacts the user and an outer surface that faces the inner surface. Examples of sanitary products having an inner surface and an outer surface include disposable diapers, urine absorption pads, incontinence pads, sanitary napkins, panty liners, sanitary shorts, bedsore pads, disposable masks, bandages, etc.

[0058] The outer surface can be exposed to the external environment. Examples of such sanitary products include disposable diapers (particularly disposable diapers for babies and disposable diapers for pets), disposable masks, bandages, etc. In the disposable diapers, the mosquito and mite repellent is disposed around the periphery of openings, such as a waist opening, a pair of leg openings, and a tail hole, so that the mosquito and mite repellent is easily dispersed as the wearer moves, making it less likely for the user (wearer) to come into contact with the mosquito and mite repellent.

[0059] In the sanitary product having the inner and outer surfaces, the mosquito and mite repellent can be disposed on at least one of the inner and outer surfaces of the sanitary product, and is preferably disposed only on the outer surface of the sanitary product. By disposing the mosquito and mite repellent on the outer surface of the sanitary product, the mosquito and mite repellent is more easily vaporized and the user is less likely to come into contact with the mosquito and mite repellent. Furthermore, when the outer surface is exposed to the external environment, the mosquito and mite repellent is more easily vaporized and the user is less likely to come into contact with the mosquito and mite repellent. When the sanitary product is a disposable diaper, for example, the mosquito and mite repellent can be disposed in the repellent area disclosed in JP 2021-278 A.

[0060] The sanitary product may have an inner surface that contacts the user and a support surface that faces the inner surface and contacts an object placed on it. Examples of sanitary products that have the inner surface and the support surface include pet sheets and bed sheets.

[0061] In the sanitary product having the above-mentioned inner surface and mounting surface, the mosquito and mite repellent can be disposed on at least one of the inner surface and the mounting surface of the sanitary product, and is preferably disposed on the inner surface of the sanitary product. By disposing the mosquito and mite repellent on the inner surface of the sanitary product, the mosquito and mite repellent is more likely to volatilize. Furthermore, by storing the sanitary product having the above-mentioned inner surface and mounting surface in a folded state, the mosquito and mite repellent is covered by the liquid-impermeable sheet, regardless of whether it is disposed on the inner surface or the mounting surface, and therefore the mosquito and mite repellent is less likely to volatilize during storage.

[0062] The method for applying the mite repellent to the hygiene product is not particularly limited, and the mite repellent can be applied to the hygiene product by any application method known in the art. Examples of the application method include spray coating, coater coating, etc. The mite repellent may be held in microcapsules, and the mite repellent can be applied to the hygiene product by spraying a solution containing microcapsules encapsulating the mite repellent.

[0065] The pet diaper 1 has an inner surface (not shown) that comes into contact with the pet and an outer surface 11 that is exposed to the external environment, and the outer surface 11 is provided with a total of two mosquito and mite repellents 13 that extend in the width direction W. The two mosquito and mite repellents 13 are arranged on the outer surface 11 of the pet diaper 1 so as to be located on the sides of the pet when the pet diaper 1 is worn by the pet.

[0066] As shown in Figure 2, when the pet diaper 1 is worn by a pet 15, one of the two mosquito and tick repellents 13 is placed on the right side of the pet and the other is placed on the left side of the pet, providing excellent mosquito and tick repellency for the pet.

[0067] 3 and 4 are diagrams illustrating other examples of the placement of the mosquito and tick repellent 13 in the hygiene product according to the present disclosure, specifically, in the pet diaper 1. Specifically, Fig. 3 is a development view of the outer surface of the pet diaper 1. Fig. 4 is a diagram illustrating the state in which the pet diaper 1 is worn by a pet (specifically, a dog).

[0068] The pet diaper 1 is worn to cover a pet's abdomen, crotch area, and back. The pet diaper 1 includes a main body 3, an absorbent 5, a joint 9 (specifically, a fastening tape), and a tail hole 17. The pet diaper 1 has a longitudinal direction L and a width direction W, and is worn to cover a pet's abdomen, crotch area, and back, with the width direction W coinciding with the pet's waist circumference. Note that the pet diaper 1 has a structure well known in the art, and therefore a detailed description thereof will be omitted.

[0069] The pet diaper 1 has an inner surface (not shown) that comes into contact with the pet and an outer surface 11 that comes into contact with the external environment, and the outer surface 11 is provided with a mosquito and mite repellent 13 that extends in the width direction W. The mosquito and mite repellent 13 is disposed on the outer surface 11 of the pet diaper 1 so as to be located on the back of the pet when the pet diaper 1 is worn by the pet.

[0070] As shown in Figure 4, when the pet diaper 1 is worn by a pet 15, the mosquito and tick repellent 13 is placed on the back of the pet, so the pet has excellent mosquito and tick repellency.

Two glass tubes 103 (length: 240 mm, diameter: 45 mm) were prepared, and one end of each of the two glass tubes was sealed with a lid 105 made of nylon mesh (18 mesh). Nylon mesh (18 mesh) was used to form a cylinder 107 (length: 100 mm, diameter: 40 mm), and an insect release port 109 (15 mm x 15 mm) was formed in the center. Glass tubes 103 were connected to both ends of the cylinder 107 so that the cylinder 107 was inserted 2 cm into each end, and the gaps were sealed. The right glass tube 103 is referred to as test area 111, and the left glass tube 103 is referred to as blank area 113.

[0076] (2) A repellent-containing nonwoven fabric 115 (2 cm x 2 cm) made of a spunbond nonwoven fabric with a repellent dripped into the center was placed at the right end of test area 111 (inside mosquito repellent tester 101), and a repellent-free nonwoven fabric 117 made of a spunbond nonwoven fabric with no repellent dripped into it was placed at the left end of blank area 113 (inside mosquito repellent tester 101). (3) Thirty Aedes albopictus mosquitoes (hereinafter simply referred to as "mosquitoes") were released into mosquito repellent tester 101 through insect release opening 109, and the mosquito repellency test was started by closing insect release opening 109 with cellophane tape.

[0077] (4) Repellency test: Sixty minutes after the start of the test, the mosquitoes present in the counting area 119 of the test area 111 and the mosquitoes present in the counting area 121 of the blank area 113 were counted. The counting areas 119 and 121 for counting mosquitoes were 10 cm closer to the lid 105 of the glass tube 103 (the areas not covered by the lid 105). (5) The repellency rate (%) was calculated using the following formula: Repellency rate (%) = 100 × (1 - number of mosquitoes in counting area 119 / number of mosquitoes in counting area 121). (6) The repellency rate (%) was calculated by performing a total of three tests using different mosquitoes, and the average value of the repellency rate (5) was used.

[0078] [Mite repellency test] The mite repellency test was carried out based on "8.1 Invasion prevention method" of JIS L1920:2022 "Test method for anti-mite performance of textile products." The test insects used were Dermatophagoides pteronyssinus (Tokyo Women's Medical University) reared by Yamato Chemical Industry Co., Ltd. for successive generations. The test sample was formed by placing a 40 mm diameter spunbond nonwoven fabric in a 45 mm diameter glass petri dish, placing 0.5 g of bait in the center of the spunbond nonwoven fabric, and finely dropping 20 μg of repellent on the areas other than the bait.

[0079]

[0080] Cinnamyl acetate, isoamyl salicylate and citronellal have a mosquito repellency rate of 60% or more and a mite repellency rate of 90% or more at concentrations of 20% by mass or more, demonstrating excellent mosquito and mite repellency.
