Description

  The present invention relates to a repellent foamable composition for preventing the invasion of harmful animals.

  Conventionally, as a means of extermination of harmful animals such as rats and pests, (1) solid agents containing rodenticides and insecticides and (2) traps using adhesives and mechanical devices have been used. Yes. The former is concerned about the safety of pets, infants, etc., and the latter has hygiene problems such as the effect being affected by the choice of installation location and the removal of carcasses.

  In addition to the above, the spray type spraying the foamable composition is frequently used as a simple and effective means for controlling harmful animals, and the development of new products has been attempted.

  For example, in Japanese Patent Application Laid-Open No. 2003-146819 (Patent Document 1), a composition containing a non-adhesive resin soluble in dimethyl ether and a nonionic surfactant is sprayed to cover pests on a rod-shaped body. To capture. Japanese Patent Application Laid-Open No. 2009-235023 (Patent Document 2) is a composition comprising a stock solution composed of water and a surfactant and a propellant, and devised a ratio of liquefied petroleum gas and dimethyl ether serving as a propellant. Thus, there is disclosed a foam composition that initially exhibits a sticky foam and then becomes non-sticky so as to suffocate and kill pests. Furthermore, Japanese Patent No. 4870312 (Patent Document 3) discloses a biocidal composition containing a specific gelling agent and silica, which is a foam gel but can be sprayed over a long distance in the same manner as a liquid. A composition is disclosed.

  The inventions described in these documents all relate to a foam composition (foamable composition) devised with the aim of improving the efficiency of directly capturing and exterminating harmful animals. On the other hand, the foam containing an aversive component for harmful animals can be kept in a predetermined place while maintaining its form for a long period of time, and can be easily and cleanly removed as needed after use. There is no conventional foaming technology.

JP 2003-146819 A JP 2009-235033 Japanese Patent No. 4870312

  The present invention maintains a foam containing an aversive component disliked by harmful animals for a long period of time to prevent the invasion of harmful animals, and after use, the foam can be washed out easily and cleanly. The object is to provide a new type of effervescent composition for repelling harmful animals.

  As a result of intensive studies to solve the above-mentioned problems, the present inventors have found that a specific fat is contained in a foaming agent composition (foaming basic ingredient) composed of water and a surfactant together with an aversive ingredient that is harmful to harmful animals. By containing a small amount of a group monohydric alcohol and / or these ethylene oxide adducts and a water-soluble polymer, foam that lasts for a long time can be formed, and the foam can be easily removed as needed. It has been found that a foamable composition is obtained.

  Thus, the present invention provides (1) a higher aliphatic monohydric alcohol and / or a higher aliphatic monohydric alcohol ethylene oxide having 1 or 2 added moles in a foaming agent composition containing water and a surfactant. It is intended to provide a foamable composition for repelling harmful animals, comprising an adduct, (2) a film-forming water-soluble polymer, and (3) an aversive component disliked by harmful animals.

  Furthermore, according to the present invention, there is provided a harmful animal repelling device characterized in that the foamable composition is used after being foamed by an electrical foaming means, an aerosol, a pump former or the like.

When the composition of the present invention is fired, a foam containing an aversive component that a harmful animal dislikes lasts for a long time. Intrusion can be prevented by blocking the path and preventing it from approaching. If the composition of the present invention is used to prevent the invasion of harmful animals, it will be hygienic because it will not leave the dead body of the harmful animals. Safe because it contains no chemicals. Moreover, since the composition of the present invention can be easily washed away with water after use, it is excellent in convenience.
The composition of the present invention can be easily foamed by applying it to an existing pump former, aerosol, or electrical foaming means.

  One of the characteristics of the foamable composition of the present invention is that the number of moles of higher aliphatic monohydric alcohol and / or (ethylene oxide) added is 1 or 2 in the foamed basic composition comprising water and a surfactant. It contains an ethylene oxide adduct of a higher aliphatic monohydric alcohol (also referred to as an ether compound of a higher aliphatic monohydric alcohol and ethylene oxide or a (poly) oxyethylene higher aliphatic ether). .

  Here, the higher aliphatic in the above-mentioned higher aliphatic monohydric alcohol or ethylene oxide adduct of higher aliphatic monohydric alcohol generally refers to a chain structure having 12 to 18 carbon atoms. . When a higher aliphatic monohydric alcohol having a carbon number of less than 12 and / or an ethylene oxide adduct of a higher aliphatic monohydric alcohol having an addition mole number of 1 or 2, sufficient foam life is obtained. On the other hand, when an ethylene oxide adduct of a higher aliphatic monohydric alcohol having a carbon number greater than 18 and / or a higher aliphatic monohydric alcohol having 1 or 2 added moles is used, the viscosity is increased and foamed. The ability decreases and the tendency of these compounds to precipitate without being completely dissolved is increased.

  Thus, preferred examples of the higher aliphatic monohydric alcohol used in the foamable composition of the present invention include oleyl alcohol, cetyl alcohol, stearyl alcohol, isostearyl alcohol, cetostearyl alcohol, myristyl alcohol, lauryl alcohol and the like. be able to. Examples of ethylene oxide adducts of higher aliphatic monohydric alcohols having an addition mole number of 1 or 2 suitable for use in the foamable composition of the present invention include polyoxyethylene cetyl ether 2EO, polyoxy And oleyl ether 2EO. The higher aliphatic monohydric alcohols may be used alone or in combination of two or more. Similarly, an ethylene oxide adduct of a higher aliphatic monohydric alcohol having 1 or 2 added moles can also be used.

  The content of the higher aliphatic monohydric alcohol and / or ethylene oxide adduct of the higher aliphatic monohydric alcohol having 1 or 2 added moles used in the foamable composition of the present invention is preferably the whole composition 0.1 to 4% by weight, and more preferably 0.5 to 2% by weight. When the content is less than 0.1% by weight, the life of the foam is shortened. On the other hand, when the content is more than 4% by weight, the foaming ability decreases due to thickening, and higher aliphatic alcohol and / or An ethylene oxide adduct of a higher aliphatic monohydric alcohol having an addition mole number of 1 or 2 cannot be dissolved and precipitates.

  A further feature of the foamable composition of the present invention is that a higher aliphatic monohydric alcohol and / or a higher mole number of 1 or 2 as described above is contained in the foamed basic composition comprising water and a surfactant. In addition to the ethylene oxide adduct of aliphatic monohydric alcohol, a film-forming water-soluble polymer is contained. This ensures the formation of a foam that has a long life and can be easily washed away. As the film-forming water-soluble polymer of the composition of the present invention, various water-soluble polymers conventionally used for the purpose of film formation can be basically used as described below.

  For example, an anionic polymer comprising acrylic acid copolymer or methacrylic acid copolymer (copolymer), vinyl acetate copolymer, or maleic acid copolymer can be used as the film-forming water-soluble polymer in the foamable composition of the present invention. In particular, the acrylic acid copolymer or methacrylic acid copolymer is a general term for acrylic resin alkanolamine liquid [(alkyl acrylate / diacetone acrylamide) copolymer, alkyl acrylate copolymer, and the like. ], Octylamide acrylate / hydroxypropyl acrylate / butylaminoethyl methacrylate copolymer, hydroxyethyl acrylate / butyl acrylate / methoxyethyl acrylate copolymer, (acrylates / stearyl acrylate / ethylamine methacrylate oxide) copolymer, etc. Examples of the vinyl acetate copolymer include vinyl acetate / vinyl pyrrolidone copolymer and vinyl acetate / crotonic acid copolymer, and examples of the maleic acid copolymer include methoxyethylene maleic anhydride copolymer.

Can be mentioned.

  Examples of particularly preferred film-forming water-soluble polymers for use in the foamable composition of the present invention are those comprising copolymers containing an acrylic acid structure or a methacrylic acid structure. That is, in addition to the acrylic acid copolymer or methacrylic acid copolymer described above as an anionic polymer, an amphoteric polymer (part) and / or a cationic polymer (part) are added to an acrylic acid polymer (part) or a methacrylic acid polymer (part). It has been found that water-soluble polymers comprising (bonded) copolymers are suitable as film-forming water-soluble polymers of the foamable composition of the present invention.
