Description

[Technical field]

[0001] The present invention relates to a fragrance or fragrance composition for masking unpleasant odors emanating from dog and cat feces and urine. [Background technology]

[0002] In recent years, the number of dogs and cats being kept as pets has been on the rise due to the pet boom. With more time spent at home due to teleworking and other reasons, more people are starting to keep dogs and cats, but there is a problem with the smell of feces and urine. Although research has been done on the smell of pet feces and urine, ammonia and fatty acids have been cited as the main causes, and in the case of cat urine, 3-mercapto-3-methylbutanol (hereinafter referred to as 3MMB) has been cited as a particular cause. However, it is known that 3MMB is not detected in large amounts in samples from neutered or spayed animals, and since most pets are neutered or spayed, it is thought that odorous components other than 3MMB contribute to the discomfort of owners when taking care of cat litter boxes. However, these components have not been identified, and no effective deodorizing or masking methods have been found. On the other hand, a fragrance composition for deodorizing pet odors that has a deodorizing effect on the odor of urine of pets and animals and the odor of cat excrement is known. For example, Patent Document 1 and Patent Document 2 disclose deodorizing fragrance compositions containing specific fragrance ingredients. In addition, a fragrance composition for deodorizing cat urine odors that has a deodorizing effect on the odor of urine of elderly cats aged 7 years or older is known, but none of them have been able to specifically identify the unpleasant odor.
