Description

The present invention relates to a composition for reducing malodorous compounds having an indole skeleton.

Generally, odors are ubiquitous in the environment. While some odors are perceived as pleasant, there are also malodours, which are odors that cause unpleasant sensations, and many methods of controlling malodors are continually being explored.

For example, one source of malodor is all kinds of discarded human and animal bodily wastes, liquids and secretions. Other sources of unpleasant odors that need to be controlled are also caused by foods such as dairy products, meat and fish, or textiles, furniture and wall coverings.

Indole compounds are known as odorants with respect to human and animal bodily wastes, liquids and secretions and are used e.g. in sanitary napkins, pantiliners, adult There are personal hygiene products such as incontinence products, baby diapers, paper towels, toilet paper and toilet paper. Such articles are often used to absorb and dispose of bodily fluids and other exudates excreted by the human body, thereby reducing odor discomfort.

[Example: Reduction test of indole-like odor and benzaldehyde odor]
In the composition according to one aspect of the present invention, the following tests were carried out in order to examine what molar ratios of benzaldehyde and hexylcinnamic aldehyde are effective against indole-like odor and benzaldehyde odor. gone. An indole-like odor refers to a malodor after reaction (eg, an unreacted indole odor, and an odor that the subject perceives as similar to indole, although it is not the odor of indole itself).

Indole, benzaldehyde, hexyl cinnamic aldehyde (hereinafter also referred to as HCA), and lactic acid were dissolved in methanol to the molar concentrations shown in Table 1, and samples were prepared so that the total volume of the solution was 1 mL. The samples were allowed to stand at 35°C for 24 hours before testing. The strength of the indole-like odor and benzaldehyde odor of the sample was evaluated by 20 subjects on a 5-point scale. In addition, the 5-grade evaluation is performed as follows: "1" is very strong, "2" is strong, "3" is weak, "4" is weak, and "5" is hardly understood. The average value of was calculated. When the average value was 4.0 to 5.0, it was evaluated as ⊚, when it was 2.0 to 4.0 as ◯, and when it was 1.0 to 2.0 as Δ. Table 1 shows the results.

As shown in Table 1, it was shown that indole-like odor and benzaldehyde odor are well suppressed when the molar ratio range of benzaldehyde:hexylcinnamic aldehyde is from 1:1/3 to 100.

[Reference example: performance test of aldehyde compounds]
In order to confirm the bad odor reducing effect of aldehyde compounds, the following quantitative tests were conducted using various perfumes.

Next, indole, various compounds, and lactic acid were dissolved in methanol so as to have the concentrations shown in Table 2, and samples were prepared so that the total volume of the solution was 1 mL. The various compounds used were (3) benzaldehyde, (4) hexyl cinnamic aldehyde, (5) benzyl salicylate, (6) limonene, and (7) hexyl salicylate. The sample was allowed to stand at 45° C. for 1 day and used as a measurement sample to calculate the rate of reduction of indole.

The reduction rate was calculated by the following method. First, 1 mL of a methanol solution containing 0.1 mol/L of indole was analyzed with a gas chromatography analyzer manufactured by Agilent Technologies, Inc., and the peak area derived from indole was calculated. area. Next, the measurement sample was analyzed with a gas chromatography analyzer to measure the peak area derived from indole. The reduction rate of indole was calculated by comparing the area of the reference sample and the area of the measurement sample. Evaluation was made on a 4-point scale: 1 when the rate of decrease was 0 to 25%, 2 when the rate of decrease was 26 to 50%, 3 when the rate of decrease was 51 to 75%, and 4 when the rate of decrease was 76 to 100%. Table 2 shows the results.

As shown in Table 2, in the comparative examples, the amount of indole after testing decreased by 0-25% compared to the reference samples. In contrast, in the reference examples with samples containing benzaldehyde or hexyl cinnamic, the amount of indole after testing decreased by 51-75% compared to the reference samples. That is, it was shown that the amount of indole was reduced by the aldehyde compound.

[Reference example: Evaluation of types of organic acids]
In order to investigate which kind of organic acid is effective, the following test was conducted.

The test was conducted in the same manner as [Reference Example: Performance Test of Aldehyde Compound] except that the type and molar concentration of the organic acid were different. The measurement sample was analyzed with a gas chromatography analyzer, and the peak area derived from indole was measured. The reduction rate of indole was calculated by comparing the area of the reference sample and the area of the measurement sample. Evaluation was made on a 4-point scale: 1 when the rate of decrease was 0 to 25%, 2 when the rate of decrease was 26 to 50%, 3 when the rate of decrease was 51 to 75%, and 4 when the rate of decrease was 76 to 100%. Table 3 shows the results.

As shown in Table 3, in Comparative Example 3-1 in which no organic acid was present, the amount of indole did not decrease at all compared to the reference sample. In contrast, in the reference example in which an organic acid was present, the amount of indole in the measurement sample decreased compared to the reference sample. It was shown that benzaldehyde effectively reacted with indole in the presence of organic acid to reduce the amount of indole.

In addition, in Reference Examples 3-1 to 3-4 using samples containing hydroxycarboxylic acid having a hydroxyl group in the molecule, the amount of indole after the test decreased by 26% or more compared to the reference sample. That is, it was shown that hydroxycarboxylic acid is effective among organic acids.
