DESCRIPTION:
BRIEF SUMMARY
TECHNOLOGICAL FIELD
The invention relates to a repelling material for animals prepared by adsorbing an repellent on active carbon fiber.
BACKGROUND ART
As a repellent preventing animals from approaching, cinnamic aldehyde, .gamma.-nonylolactone, rosegeranium oil, sandalwood oil, menthol, citral, cinnamic alcohol, methyleugenol, geraniol, linalool and the like are known. In addition, limonene and the like are known as disclosed in Japanese Unexamined Patent Publication No. 110602/89.
As disclosed in the above-mentioned publication, said repellents were applied to an objective place in themselves or in the form of preparations with the addition of diluent, extending agent, retaining agent, excipient, emulsifier and the like by the following means: as gelatin, polyvinylalcohol, maltose and the like and puting the capsule at an objective place. paper or the like and putting the bag at an objective place. into a melt of synthetic resin material. the paper with a film made of polyethylene and like synthetic resin.
A conventional repelling material for animals produced by retaining a repellent (e.g. repelling material for animals, birds and the like) on a granulated active carbon has only a short life so that development of a repelling material for animals retaining more amount of a repellent, gradually releasing the repellent and having a long life is earnestly desired.
DISCLOSURE OF THE INVENTION
The inventors have conducted an extensive research on a repelling material for animals retaining more amount of a repellent, gradually releasing the repellent and having a long life, found that a repelling material for animals retaining more amount of a repellent, not rapidly releasing the retained repellent and having a long life can be produced by using special chemical substances as a sustained release agent, and accomplish the invention.
Thus, the present invention relates to "a repelling material for animals adsorbing at least one substance of phthalic acid esters, citric acid esters and glycols and an repellent on active carbon fiber".
As active carbon fibers, each fiber derived from pitch, polyacrylonitriles (PAN), phenols, celluloses and the like can be used.
The active carbon fiber is usually about 2 to about 3 .mu.m in diameter of fiber, about 500 to about 2500 m.sup.2 /g in specific surface area, about 10 to about 40 .ANG. in diameter of pore, and distribution of pore size of the active carbon fiber is sharp.
As a repellent, a variety of chemical substances can be selected in accordance with a field of application.
In case of an animal repellent, the following chemical substances can be exemplified.
As repellents for dogs and cats, one or more of cinnamic aldehyde, .gamma.-nonylolactone, lemon oil, paracresol acetate and the like can be used.
As repellents for pigeons, sparrows, bulbuls and like birds, one or more of phenylethylalcohol, geraniol, rosegeranium oil (a general term of benzylbenzoate, linalylacetate, linalool etc.), spearmint oil, L-carvone, bornylacetate, camphor, tetrahydrothiophene, citronellol and the like can be used.
As repellents for cockroaches, one or more of cinnamic alcohol, methyleugenol, geraniol and the like can be used.
As repellents for mosquitoes, one or more of sandalwood oil, menthol, citral and the like can be used.
However, a repelling material for animals has a short life by simply retaining the repellent only on a carrier due to rapid release of the repellent in a short time. The inventors conducted a further extensive research on a sustained release agent exerted an excellent sustained release effect and found that phthalic acid esters, citric acid esters or glycols exerted a desired effect. The chemical substances exerting a sustained release effect are exemplified such as: diethylphthalate, dibutylphthalate and the like being exemplified as esters of phthalic acid; triethylcitrate, trimethylcitrate and the like being exemplified as esters of citric acid; dipropylene glycol, butyldiglycol and the like being exemplified as glycols.
