Description

[Technical field]

[0001] The present invention relates to a liquid spray composition. In particular, the present invention relates to a liquid spray composition having excellent deodorizing properties, stability, and spray properties. [Background technology]

[0002] In recent years, with the trend towards saving water and growing environmental awareness, there is a growing need for spray-type disinfectants and deodorizers as a way to easily refresh clothes without washing them. In addition to hygienic effects such as disinfection and antibacterial properties, there is a demand for further improvements in the deodorizing effect that is easily recognized by users. As deodorizing techniques, those using a metal complex of a metal ion and a chelating agent (Patent Document 1) and those using a fatty acid zinc salt (Patent Document 2) have been proposed. However, while zinc salts have an excellent deodorizing effect, polyvalent metal ions such as zinc often interact with thickeners to reduce viscosity, limiting the thickeners that can be used. In addition, when the viscosity of the composition is reduced, it becomes difficult to incorporate particles such as capsule fragrances from the standpoint of stability, which limits the freedom of the composition. However, there is a problem that if the amount of thickener incorporated is increased to maintain the viscosity, the spray properties of the spray deteriorate.

[0038] <Spray properties> The liquid spray composition was sprayed once onto the center of a color broadcloth (blue, 20 cm x 20 cm) used as a test cloth, from a distance of 20 cm, using a trigger spray (NANOX spray, manufactured by Lion Corporation). When sprayed, the width of the wetted area where the composition adhered was measured, and the ease of spraying uniformly onto the test cloth was evaluated by four evaluators according to the following evaluation criteria. Evaluation was made based on the average score of the four evaluators according to the following evaluation criteria, and the results are shown in the "sprayability" section in Table 2 below. (Evaluation Criteria) 3 points: Can be sprayed in a circular shape (diameter 8 cm or more). 2 points: Can be sprayed in a circular shape (diameter 4 cm or more). 1 point: Circular spray is possible, but the diameter is less than 4 cm. 0 points: The spray cannot be produced in a circular shape or is produced in a straight line. (Judgment criteria) 〇〇: Average score 2.5 points or more ○: Average score 1.5 points or more and less than 2.5 points ×: Average score less than 1.5 points

[0039] <Deodorizing performance> 100 μl of a 0.5% nonanoic acid / ethanol solution was dropped onto a cotton knit cloth (5 cm×5 cm) and left to stand for 20 minutes to prepare a test cloth. 0.2 g of the liquid spray composition was sprayed evenly onto the test cloth using a dispenser pump spray (Style Guard Wrinkle and Odor Relief Spray, manufactured by Lion Corporation). After leaving it for 30 minutes, the odor intensity was scored by four evaluators according to the following six-level odor intensity rating method. Judgment was made based on the average score of the four evaluators according to the following criteria, and the results are shown in the "Deodorizing Properties" section of Table 2 below. (6-level odor intensity rating system) 5 points: Strong odor 4 points: Strong odor 3 points: The odor is strong enough to be easily detected 2 points: The odor is strong enough that you can tell what it is. 1 point: The odor is barely detectable 0 points: Odorless (Judgment criteria) 〇〇: Average score less than 1 point ○: Average score is 1 point or more but less than 2 points ×: Average score of 2 points or more
