Description

The present invention relates to a deodorant composition capable of stably dispersing zirconium hydride.

In recent years, along with the increasing demand for comfort in life, the need for odor control to make living space comfortable is also increasing. Conventionally, as a measure against odors in daily life, a method of using a deodorant such as a spray type, an aerosol type, or a stationary type to spray or volatilize in a space is known. In such deodorants, plant extracts such as polyphenols, organic deodorant components, and the like are often used as deodorant components. On the other hand, as an odor control product, a product in which a deodorant component is attached to a material such as wallpaper, a ceiling, and a cloth to add a deodorant function in advance has also been developed. In such products, inorganic deodorant components such as porous materials and metal compounds are often used as deodorant components.

In general, it is known that the inorganic deodorant component has a higher deodorizing effect than the organic deodorant component, and in deodorants such as spray type, aerosol type, and stationary type, the inorganic deodorant component is used. High deodorant effect is expected when the ingredients are used.

However, the inorganic deodorant component often has poor dispersibility in a solvent such as water, and when blended with a deodorant, it has a drawback that it becomes cloudy or aggregates. Such cloudiness or aggregation of the inorganic deodorant component makes it impossible to effectively exert the deodorizing action inherent in the inorganic deodorant component. Conventionally, when attaching an inorganic deodorant component to a material such as wallpaper, ceiling, or cloth, a method of using an additive such as a surfactant or a thickener to improve the dispersibility of the inorganic deodorant component has been used. However, since such additives are non-volatile (see, for example, Patent Documents 1 and 2), when they are blended with a deodorant and applied to clothes, walls, etc., the additive is applied to the place of application. There is a concern that it may remain and spoil its texture and appearance. In addition, the deodorant may freeze, for example, during the distribution process in winter or when stored in a warehouse in a cold region. Therefore, a deodorant containing an inorganic deodorant component is required to be uniformly dispersed after thawing even if it is once frozen in this way.

Against the background of such conventional techniques, there is an urgent need to develop a deodorant capable of stably dispersing inorganic deodorant components.

Test Example 1
Deodorant compositions having the compositions shown in Table 1 were prepared, and 10 g of each deodorant composition was filled in a 20 mL transparent glass container. Further, LAQUAtwin-pH-11B (manufactured by HORIBA Scientific) was used for measuring the pH of the deodorant composition. The appearance immediately after filling was visually observed, and the dispersibility of zirconium hydride in the deodorant composition was evaluated according to the following criteria. When the evaluation result is ⊚ or ◯, it can be said that there is good dispersibility that can satisfy the practical level.
<Criteria for determining dispersibility>
⊚: Colorless and transparent, and the dispersibility is sufficiently maintained.
◯: A slight cloudiness is observed, but no obvious agglomerates are visible.
Δ: White turbidity is observed, and clear agglomerates can be visually recognized.
X: Significant cloudiness is observed, and clear agglomerates can be visually recognized.

The results obtained are shown in Table 1. In the deodorant composition of Comparative Example 1, cloudy and clear aggregates were visually recognized, and the dispersibility of zirconium hydride was inferior. On the other hand, in the deodorant compositions of Examples 1 to 7, no obvious aggregates were visually recognized, and zirconium hydride was well dispersed. From the above results, it was clarified that zirconium hydride can be stably dispersed when the pH is 6.0 or less, including zirconium hydride, ethanol, and water.

Test Example 2
A deodorant composition having the composition shown in Table 2 was prepared. Further, LAQUAtwin-pH-11B (manufactured by HORIBA Scientific) was used for measuring the pH of the deodorant composition.

2.5 g of each deodorant composition was added dropwise to a cotton (Kanakin No. 3) single fiber cloth (12.5 cm × 10 cm). A cotton single fiber cloth immediately after dropping the deodorant composition was used as a test piece (wet condition). Separately, a cotton single fiber cloth on which the deodorant composition was dropped was dried by allowing it to stand overnight, and was prepared as a test piece (drying conditions). In addition, as a control sample, a test piece prepared by performing the above treatment using water instead of the deodorant composition was prepared.

The test piece was placed in a 10 L volume Tedlar bag (made of polyvinyl fluoride), sealed and degassed, and then the inside of the Tedlar bag was filled with 5 L of odorless air. Next, ammonia or trimethylamine was injected into a tedler bag containing the test piece so as to be about 50 ppm, and the mixture was allowed to stand at room temperature, and the malodor concentration was measured over time. For the measurement of ammonia, use the ammonia detector tube No. For the measurement of 3La (Gastec) and trimethylamine, the amine detector tube No. 180 (Gas Tech) was used. In addition, amines detector tube No. Since 180 interferes with alcohol, when measuring trimethylamine under wet conditions, the ammonia detector tube No. 180 is used. The value measured using 3La (Gastec) was substituted by converting it into the amount of trimethylamine. Next, the deodorizing rate of the test piece to which the deodorant composition was dropped was calculated according to the following formula.

Based on the deodorizing rate of each deodorant composition, the deodorizing effect was evaluated according to the following criteria. If the evaluation is ◎◎, ◎ or ○ after 300 minutes, it can be said that there is a deodorizing effect that can satisfy the practical level. The sample judged as ◎◎ before the lapse of 300 minutes was considered to have a sufficient deodorizing effect, and the test was interrupted at that point.
<Criteria for deodorant effect>
◎ ◎: Deodorant rate is 90% or more ◎: Deodorant rate is 70% or more and less than 90% ○: Deodorant rate is 50% or more and less than 70% △: Deodorant rate is 30% or more and less than 50% × : Deodorant rate is 10% or more, less than 30% XX: Deodorant rate is less than 10%

Test Example 3
Deodorant compositions having the compositions shown in Tables 3 and 4 were prepared. Further, LAQUAtwin-pH-11B (manufactured by HORIBA Scientific) was used for measuring the pH of the deodorant composition. With respect to the obtained deodorant composition, the dispersibility of zirconium hydride was evaluated by the same method as in Test Example 1 (dispersability without freezing and thawing).

10 g of each deodorant composition was filled in a 20 mL transparent glass container, allowed to stand in a freezer set at −20 ° C. for 8 hours, and then allowed to stand at room temperature for 8 hours to freeze and thaw. After completely thawing, the appearance of the deodorant composition was visually observed, and the dispersibility after freezing and thawing was evaluated according to the following criteria. When the evaluation result is ⊚ or ◯, it can be said that there is good dispersibility that can satisfy the practical level.
<Criteria for determining dispersibility after freezing and thawing>
⊚: Colorless and transparent, and the dispersibility is sufficiently maintained.
◯: A slight cloudiness is observed, but no obvious agglomerates are visible.
Δ: White turbidity is observed, and clear agglomerates can be visually recognized.
X: Significant cloudiness is observed, and clear agglomerates can be visually recognized.

The results obtained are shown in Tables 3 and 4. As a result, it was confirmed that the deodorant compositions of Examples 9 to 22 were able to stably maintain the dispersibility of zirconium hydride even after freezing and thawing. That is, from this result, the solvent contains monohydric alkyl alcohol, alkoxy alcohol, polyalkylene glycol, alkylene glycol monoalkyl ether, polyalkylene glycol monoalkyl ether, polyalkylene glycol dialkyl ether, or alkylene glycol difatty acid ester.

Test Example 4
A deodorant composition having the composition shown in Table 5 was prepared, and the deodorizing effect on trimethylamine was evaluated by the same method as the drying conditions in Test Example 2. LAQUAtwin-pH-11B (manufactured by HORIBA Scientific) was used for measuring the pH of the deodorant composition.

The results obtained are shown in Table 5. The deodorant composition of Comparative Example 3 had a deodorizing rate of less than 10% with respect to trimethylamine, whereas the deodorant compositions of Examples 23 to 25 had an excellent deodorizing effect.
