Description

  The present invention relates to a shampoo composition for animals, and more particularly, an shampoo composition for animals capable of effectively removing ectoparasites such as moths parasitic on animals such as dogs and cats, and the shampoo composition for animals. The present invention relates to a method for controlling ectoparasites using objects.

  In recent years, with the diversification of hobbies, there are an increasing number of lovers who keep animals such as dogs and cats as pets. Many pets are kept as part of a family, and many owners strive to keep their pets in good health so that pet animals can live a comfortable life. Under such circumstances, the problem that ectoparasites such as moths infest pets is well-known, and when pets are stabbed into moths, itching and itching, causing allergic dermatitis, tapeworms, etc. May cause problems such as being borne by parasites. For this reason, the owners prevent pets from parasitizing ectoparasites such as pupae and eliminate them when they are infested.

  Under such circumstances, it is known that the most simple method for eliminating ectoparasites such as pupae is to wash the animals with a shampoo. Animal shampoos usually contain an insecticidal component that kills or ovaries ectoparasites such as moths, and ectoparasites such as moths are controlled by the effectiveness of the insecticidal components. For example, in Patent Document 1, as a liquid composition used for ectoparasite control, a pyrethroid insecticide 0.001 to 5% by weight (mass%), an anionic surfactant 10 to 70% by weight (mass%) And a liquid composition containing 0.5 to 40% by weight (mass%) of glycol ethers (Claim 1).

JP, 2003-192505, A Claims

  However, in the liquid composition described in Patent Document 1, when the addition amount of the pyrethroid insecticide is small, the insecticidal ability against ectoparasites such as moths is insufficient, and if the addition amount of the insecticide is increased, There were problems that caused side effects such as toxicity and irritation to humans.

  Accordingly, an object of the present invention is to provide an animal shampoo composition which is effective for controlling ectoparasites such as pupae with a small amount of insecticidal components.

  As a result of intensive studies to solve the above problems, the present inventors have found an animal shampoo composition that can improve the insecticidal effect by using a compound having a specific structure and an insecticidal component in combination. The present invention has been completed by finding out that it can be provided.

Among these anionic surfactants, sulfate ester salts and sulfonate salts are preferable, sulfate ester salts are more preferable, and polyoxyethylene alkyl ether sulfate ester salts are most preferable.

  The anionic surfactant which is the component (A) of the present invention can be blended in an amount of 1 to 50% by weight, preferably 3 to 40% by weight, more preferably 5 to 35% by weight based on the whole animal shampoo composition. %. When the blending amount of the component (A) is less than 1% by mass, the foaming of the animal shampoo composition may deteriorate, and when it exceeds 50% by mass, the animal shampoo composition may be separated or solidified. This is not preferable because the product stability may deteriorate.

（式中、Ｒ^１〜Ｒ^３は、それぞれ炭素数１〜３のアルキル基を示し、同一であっても異なっていてもよく、ｍ＋ｎ＝５〜１００且つｍ＝０〜３であり、Ｘはハロゲン原子またはＣＨ_３ＳＯ_４を示し、ｍ／（ｍ＋ｎ）＜０．２である） The component (B) used in the present invention is a polyether type quaternary ammonium salt represented by the following general formula (1):

(Wherein R ^{1 to} R ³ each represent an alkyl group having 1 to 3 carbon atoms, and may be the same or different, and m + n = 5 to 100 and m = 0 to 3; Represents a halogen atom or CH ₃ SO ₄ and m / (m + n) <0.2)

  In the said General formula (1), although m + n is 5-100, 5-80 are preferable and 5-50 are more preferable. When m + n is less than 5 and more than 100, or when m> 3 and m / (m + n) is greater than 0.2, the shampoo composition for animals cannot be contributed to the improvement of the insecticidal effect. This is not preferable because the foaming of the liquid becomes worse. If the foaming deteriorates, the cleaning composition does not reach the entire body of the animal to be cleaned, and as a result, the ectoparasites that parasitize the animal to be cleaned cannot be controlled.

  The polyether type quaternary ammonium salt which is the component (B) of the present invention can be blended in an amount of 0.1 to 10% by weight, preferably 0.5 to 8% by weight based on the whole animal shampoo composition. %, More preferably 1 to 5% by mass. When the blending amount of the component (B) is less than 0.1% by mass, a synergistic effect with the insecticidal component is not observed, and when it exceeds 10% by mass, an effect commensurate with the blending amount cannot be expected.

  The component (C) of the present invention is an insecticidal component. Examples of the insecticidal component include resmethrin, cadreslin, cyhalothrin, bifenthrin, fenpropatoline, allethrin, tralomethrin, fenvalerate, flucitrinate, fulvalinate, cycloprotorin, etofenprox, fubufenprox, 1- (3-phenoxy Phenyl) -4- (4-ethoxyphenyl) -4-methylpentane, 1- (3-phenoxy-4-fluorophenyl) -4- (4-ethoxyphenyl) -4-methylpentane, dimethyl- (4-ethoxy) Pyrethroid insecticide components such as phenyl)-(3-phenoxybenzyloxy) methylsilane and silafluophene; organophosphorus compounds such as fenitrothion, fenthion, diazinon, dichlorvos, trikilophone, prothiophos, pidafontione Insect component; carbaryl, fenobucarb, mention may be made of one or a mixture of two or more of such carbamate insecticide components such Puropokusa. Among these, a pyrethroid insecticidal component is preferable, and allethrin is most preferable.

It is 01-0.8 mass%, More preferably, it is 0.02-0.5 mass%. When the amount of component (C) is less than 0.001% by mass, an insecticidal effect cannot be expected, and when it exceeds 1% by mass, toxicity and irritation to animals and humans It is not preferable because side effects may occur.

  The animal shampoo composition of the present invention can enhance the insecticidal effect as compared with a normal animal shampoo composition containing an insecticidal component. Although the mechanism of the effect is not clear, it is likely that the overall insecticidal effect is improved by the synergistic effect of the polyether type quaternary ammonium salt having a bactericidal effect and the insecticidal component.

  Surfactants having a bactericidal effect include normal quaternary ammonium salt type surfactants, but these quaternary ammonium salt type surfactants are not excellent in compatibility with anionic surfactants and aggregate. As a result, precipitation or the like occurs. Since the polyether type quaternary anion salt which is the component (B) of the present invention is excellent in compatibility with an anionic surfactant, it does not cause aggregation or the like. In addition, if a nonionic surfactant is used instead of an anionic surfactant, a normal quaternary ammonium salt type surfactant can be added. However, nonionic surfactants can be used to wash particularly dirty animals. In this case, the basic function as a shampoo for removing dirt is inferior. In addition, when foaming deteriorates, the shampoo composition does not reach the whole body of the animal to be cleaned, and as a result, all ectoparasites that parasitize the animal to be cleaned cannot be controlled. Therefore, a combination of an anionic surfactant, a polyether type quaternary ammonium salt, and an insecticidal component is essential.
