2. Description of the Related Art In recent years, pet odor has been taken up as one of the malodors and offensive odors in the home. The cause of pet odor is
It is a malodorous substance such as a lower fatty acid and a nitrogen-containing compound, which is mainly generated by decomposing part of sebum (wax) component adhering to pet body hair or body surface by various bacteria on the body surface. In order to eliminate such bad odors and offensive odors, a pet wipe-off shampoo that does not require washing with water (Japanese Patent Laid-Open No. 63-213599) is also formulated with D-limonene and decyl aldehyde as deodorants for organic acid odors. (JP-A-6-7415) and the like have been proposed. However, even if these are used, it is difficult to continuously reduce the odorous components peculiar to pets, and it has been necessary to use a large amount or spray them frequently in order to maintain the deodorizing effect.

[0003]

DISCLOSURE OF THE INVENTION The object of the present invention is to provide a dog,
An object of the present invention is to provide a fragrance composition having an excellent deodorizing effect against the offensive odor of cats .

[0004]

Means for Solving the Problems The present inventors
In particular, the sebum component that covers the body surface of dogs has a melting point of around 50 ° C,
It has been found that the masking agent for the malodorous component hardly penetrates and remains at room temperature, so that a persistent deodorizing effect cannot be obtained. And, as described above, the animal offensive odor masking agent having poor permeability to animal sebum alone, in combination with a specific hydrocarbon, allows the masking agent to efficiently penetrate into the sebum of dogs and cats, and has a deodorant effect. continue
It was found that a fragrance composition for dogs and cats can be obtained.

The present invention is a fragrance composition for dogs and cats containing an aliphatic or alicyclic hydrocarbon of Log P3.5 to 5.5 and an animal offensive odor masking agent , wherein the masking agent is
The hydrocarbons permeate and retain the sebum of dogs and cats.
The present invention provides a fragrance composition for dogs and cats, and an external composition for dogs and cats containing the same.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The hydrocarbon used in the present invention is
LogP 3.5-5.5 aliphatic or alicyclic.
Other than this, the compatibility with the sebum of dogs and cats is low,
The deodorant effect cannot be sustained. Here, LogP is a 1-octanol / water partition coefficient of a chemical substance, and means a value obtained by calculation by the f-value method (hydrophobic fragment constant method). Specifically, the chemical structure of a compound is decomposed into its constituent elements, and the hydrophobic fragment constant (f value) of each fragment is integrated to obtain (CLOGP3 Referen

[0016]

[Table 1]

From Table 1, it was confirmed that the aliphatic or alicyclic hydrocarbons having LogP 3.5 to 5.5 and the essential oils containing them as the main components have high compatibility with animal sebum. In particular, the monocyclic terpene compounds limonene and terpinolene were confirmed to have excellent compatibility with animal sebum.

Example 1 A dry shampoo for pets having the composition shown in Table 2 was produced,
The durability of the deodorizing effect was evaluated. The results are also shown in Table 2.

(Evaluation Method) 0.5 g of dog hair of a beagle dog was dipped in each dry shampoo solution for about 20 minutes and then sufficiently dried. Immediately after this treatment, after 1 hour, after half a day, and after 1 to 4 days, the dog hair odor masking effect (animal odor) was evaluated by the following evaluation criteria according to the 6-step odor intensity prevention method used in the bad odor prevention method. Sensory evaluation was performed. 0: No animal odor is detected. 1; Smell that animal odor is barely noticeable. 2; Smell that somehow proves to be an animal odor. 3; Smell that can easily sense animal odor. 4; Smell that can be strongly sensed as animal odor. 5: Smell that animal odor can be strongly detected.

[0020]

[Table 2]

From the results shown in Table 2, it is considered that in the product of the present invention, by using limonene together, isoamyl acetate, which is an animal offensive odor masking agent, permeated and retained in animal sebum, and its deodorizing effect was maintained. On the other hand, in Comparative Product 1, isoamyl acetate has a masking effect, but its permeability to animal sebum is low, so that it volatilizes in a short time and the deodorizing effect does not continue. In Comparative Product 2, limonene penetrated into animal sebum, but the deodorizing effect alone was not sufficient. Regarding this, the comparative product 3 in which the proportion of limonene was further increased was almost the same result as the comparative product 2, and the deodorizing sustaining effect like the product of the present invention was not obtained.
