Description

  The present invention relates to a repellent for dogs and cats. More specifically, the present invention relates to a repellent for dogs and cats that exhibits an excellent repellent effect on dogs and cats.

  Traditionally, damage from dogs and cats has become a problem. For example, after disposal of household waste, plastic bags containing waste materials, paper bags, and other waste in a garbage collection site, dogs and cats eat up before the garbage truck collects them. Leftovers may be scattered on the road, giving off a bad odor and making the road surface unsanitary. In addition, biting cases caused by wild dogs and cat excrement in sandboxes such as parks have been taken up as social problems.

  Therefore, in recent years, for example, repellents containing tobacco crabs and leaves as active ingredients (see, for example, Patent Documents 1 and 2), repellents containing kerosene as an active ingredient (see, for example, Patent Document 3), lemongrass oil A repellent (eg, see Patent Document 4), a repellent containing limonene as an active ingredient (see, for example, Patent Document 5), a repellent containing a synthetic aldehyde (see, for example, Patent Document 6), etc. Various dog and cat repellents have been developed.

  The repellent has a certain repellent effect, but in recent years, development of a repellent for dogs and cats that exhibits an even better repellent effect, is superior in safety to the living body, and does not emit an unpleasant odor is desired. ing.

Examples 1-5 and Comparative Examples 1-4
Each component shown in Table 1 was mixed in the ratio shown in Table 1 to prepare a liquid repellent for dogs and cats. The odor and repellent effect of the obtained repellent for dogs and cats was examined based on the following method. The results are shown in Table 1.

(1) Odor After putting 2 x 4 cm filter paper with 0.01 g of the obtained repellent for dogs and cats into a 500 mL glass bottle, sniff the odor to a total of 10 men, 5 men and 5 women. And evaluated based on the following criteria.

(Evaluation criteria)
○: Number of people judged to feel unpleasant odor is 2 or less △: Number of people judged to feel unpleasant odor 5 to 3 people ×: Number of people judged to feel unpleasant odor 6 or more

(2) Repelling effect A 2 × 4 cm filter paper in which 0.1 g of repellent for dogs and cats was dropped was pasted on the inner surface of a food dish (made of a plastic container, diameter 10 cm) containing 150 g of adult pet food. Hereinafter referred to as processing zone).

  In addition, as a control, an untreated filter paper was attached to the inner surface of a food dish (made of a plastic container, diameter 10 cm) containing 150 g of pet food for an adult cat (hereinafter referred to as an untreated section).

  Next, 4 cats (female, 5 years old) who were fasted for one day after installing these food dishes in the center of the floor of a cat breeding shed of 200 cm x 200 cm x 200 cm Was put in a cat breeding shed, and the cat was fed. After one day, the cat's diet was terminated.

Remove the food tray from the cat breeding shed after the end of the diet, and calculate the residual rate of the food:
[Remaining rate of food]
= [Bait weight after test (g) / Bait weight before test (g)] × 100
And repellent effect was evaluated.

  From the results shown in Table 1, the repellents obtained in each Example did not emit any unpleasant odor, and the repellent containing only the isotridecyl alcohol obtained in Comparative Examples 1 and 2 and In contrast to the repellent containing only limonene, it can be seen that the repellent effect on cats is excellent. Moreover, since the repellent obtained in each Example expresses an excellent repellent effect on cats, it is judged to have an excellent repellent effect on dogs.

  Further, from the results shown in Table 1, among the repellents, repellents containing isotridecyl alcohol and limonene, repellents containing isotridecyl alcohol and cinnamic aldehyde, and cinnamic aldehyde and limonene It can be seen that repellents containing, particularly repellents containing isotridecyl alcohol and limonene, have a better repellent effect.
