Summary of the Invention

Problems to be Solved by the Invention

[0005] As a result of the study by the present inventors, it has been found that these pest repellent compositions containing water have a problem that when they are applied to fiber products containing fibers such as cotton, polyurethane, and rayon, the pest repellent effect is significantly reduced as compared with pest repellent compositions containing no water.

[0006] Therefore, the present invention aims to provide a water-containing insect repellent composition for textile treatment that exhibits excellent insect repellent effects when applied to textile products. [Means for solving the problem]

[0007] To solve the aforementioned problems, the present inventors diligently investigated the addition of components to improve the insect-repellent effect when applied to textile products in a water-containing insect-repellent composition. As a result, they discovered that adding a component having a specific chemical structure improves the insect-repellent effect when applied to textile products, leading to the completion of the present invention.

[0008] In other words, the present invention has found that the following configuration is highly effective in achieving the aforementioned objective. (1)(A) Insect repellent components, (B) Diol compounds (excluding p-menthane-3,8-diol) and (C) A fiber treatment insect repellent composition containing water. (2) The insect repellent composition for fiber treatment according to (1), wherein the (A) insect repellent component comprises one or more selected from the group consisting of picaridin, DEET, ethyl 3-(Nn-butyl-N-acetyl)aminopropionate, p-menthane-3,8-diol, and phenothrin.

[Effects of the Invention]

[0009] According to the present invention, it is possible to provide a water-containing insect repellent composition for textile treatment that exhibits excellent insect repellent effects when applied to textile products. [Modes for carrying out the invention]

[0010] The present invention describes the insect repellent composition for fiber treatment. However, the present invention is not intended to be limited to the embodiments and examples described below. In this specification, the unit of content "w / v%" is synonymous with "g / 100ml". Also, when there is a range notation "~" in this specification, it includes both the upper and lower limits.

[0011] [Insect repellent composition for textile treatment] The insect repellent composition for fiber treatment of the present invention is (A) Insect repellent components, (B) Diol compounds (excluding p-menthane-3,8-diol) and (C) This is an insect repellent composition for textile treatment containing water, and when applied to textile products, especially textile products containing fibers such as cotton, polyurethane, and rayon, it exhibits excellent insect repellent effects.

[0012] Since fibers such as cotton, polyurethane, and rayon have highly polar functional groups such as hydroxyl groups and urethane bonds in their molecules, it is presumed that when treated with a fiber treatment insect repellent composition containing (C) water, hydration occurs in the highly polar functional groups, further reducing the compatibility between the low-polarity (A) insect repellent component and the fiber. Therefore, it is thought that the adhesion of (A) insect repellent component to the fiber decreases, resulting in a reduced insect repellent effect.

[0013] Therefore, it is presumed that by adding (B) diol compounds (excluding p-menthane-3,8-diol) which possess both a highly polar structure (two hydroxyl groups) and a low-polar structure (e.g., hydrocarbon structure, ether structure, ester structure, etc.), the (B) diol compounds (excluding p-menthane-3,8-diol) act as a binder, enhancing the adhesion of (A) insect repellent components to fibers and resulting in an excellent insect repellent effect.

[0035] [Mosquito repellent efficacy test (establishment prevention, modified glass box method)] Two pieces of 100% cotton fiber, cut to 24 x 30 cm, were uniformly dripped with 0.9 mL of the insect repellent composition for fiber treatment from Example 1, and air-dried for 30 minutes. Of the four 24 x 24 cm glass plates, two were covered with the test agent-treated cloth (treated group), and the remaining two were covered with untreated cloth (untreated group). A box was constructed using the four glass plates so that the treated and untreated groups alternated. The box was placed on white paper, and the top was covered with a mesh. Test insects (20 adult female Culex pipiens) were released into the box, and the distribution of the test insects was observed within 60 minutes. The repellency rate was calculated using the following formula 1. The same tests were conducted for Examples 2-6 and Comparative Examples 1-6, and the test results are shown in Tables 1 and 2.

[0036] [Formula 1] Repellency rate (%) = {[Total number of insects anchored in the untreated area - Total number of insects anchored in the treated area] / [Total number of insects anchored in the untreated area]} × 100
