Description

[Technical Field]

[0001] The present invention relates to a deodorant composition, and more particularly to a deodorant composition that exhibits a wide range of deodorizing effects against various substances that cause malodors. [Background technology]

[0002] Odors in living spaces are composed of complex odors, such as the odors of human or animal excrement (e.g., hydrogen sulfide, ammonia), sweat odor (e.g., isovaleric acid), body odor associated with aging (e.g., 2-nonenal), food waste odor (e.g., trimethylamine, methyl mercaptan), and tobacco odor (e.g., acetaldehyde). Because odors in living spaces are composed of a combination of multiple causative substances, it is difficult to achieve sufficient deodorizing effects with a single deodorizing ingredient alone. For example, alkaline agents are highly effective at deodorizing hydrogen sulfide and lower fatty acids, but are known to be almost ineffective against alkaline substances such as ammonia and amines, which cause malodor. On the other hand, organic acids and their salts are highly effective at deodorizing alkaline substances such as amines, but are almost ineffective against hydrogen sulfide and lower fatty acids. For this reason, deodorizers that combine multiple deodorizing agents are used.

[0003] For example, Patent Document 1 discloses a deodorant composition that is effective against fatty acids, aldehydes, and amines by using a polyhydroxyamine compound and / or its salt having a specific structure in combination with an amphoteric surfactant and adjusting the pH to near neutral. However, deodorant compositions with a pH adjusted to near neutral often have poor deodorizing effect against hydrogen sulfide. [Prior art documents] [Patent documents]

[Means for solving the problem]

[0006] The present inventors have conducted extensive research to solve the above problems and have discovered that a combination of a carboxyl group-containing O-substituted monohydroxylamine or a chemically acceptable salt thereof with a betaine-type amphoteric surfactant provides a deodorizer that is effective against complex odors, thereby completing the present invention.

[0007] That is, the present invention provides a method for producing a pharmaceutical composition comprising the following components (A) to (C): (A) Carboxy group-containing O-substituted monohydroxylamine or its chemically acceptable salt (B) Betaine-type amphoteric surfactant (C)Water The deodorant composition contains:

[0008] The present invention also provides a gel-like deodorant composition obtained by absorbing the deodorant composition into a water-absorbent resin.

[0009] Furthermore, the present invention is a deodorizing method which comprises applying the deodorizing composition to a space where deodorization is desired by contact or spraying. [Effects of the Invention]

[0048] Example 1 Liquid deodorant composition: Liquid deodorant compositions were prepared by uniformly mixing all ingredients according to the formulations shown in Table 1 below. Next, 400 ml of each deodorant composition was filled into an empty container of "Shoshu-ryoku (registered trademark) for entrances and living rooms" (manufactured by S.T. Corporation) to prepare test products.

[0049] The test sample was placed in a 10-liter Tedlar bag (made of polyvinyl fluoride), sealed, and degassed. The bag was then filled with 10 liters of odorless air. The target odors were then injected into the Tedlar bag containing the test sample and allowed to stand at room temperature. The concentration of each odor was measured over time using a gas detector tube, and the time (τ0.1) until the concentration of the odorous substance fell to 1 / 10 of its initial concentration was calculated according to the data analysis method specified in the voluntary standards of the Japan Society of Deodorizers and Aromatic Deodorizers. The odorous substances and their initial concentrations used for evaluation were acetaldehyde (15 ppm), hydrogen sulfide (60 ppm), acetic acid (40 ppm), and ammonia (280 ppm). Measurements were conducted for each odor, and the results were evaluated according to the following criteria. The results are shown in Table 1.

[0051] [Table 1]

[0052] As is clear from the results in Table 1, Example 1 exhibited excellent deodorizing effects against hydrogen sulfide, acetic acid, ammonia, and acetaldehyde. In contrast, Comparative Examples 1 and 2 exhibited poor deodorizing effects against any of hydrogen sulfide, acetic acid, and acetaldehyde.

[0053] Examples 2-4 Gel deodorant composition: According to the formulation shown in Table 2 below, all ingredients were uniformly mixed to prepare a deodorant composition, which was then mixed with spherical sodium polyacrylate (average diameter before absorption: 2 mm) as a water-absorbent resin in a ratio of deodorant composition:water-absorbent resin = 97.7:2.3 to allow the water-absorbent resin to absorb the deodorant composition, preparing a gel-like deodorant composition. 50 g of each gel-like composition was placed in a 100 ml beaker, and the time (τ0.1) until the concentration of the malodor to be evaluated fell to 1 / 10 or less of the initial concentration was measured in the same manner as in Example 1, and the composition was evaluated according to the same criteria as in Example 1. The results are shown in Table 2.

[0054] [Table 2]

[0055] As is clear from the results in Table 2, Examples 2 to 4 exhibited excellent deodorizing effects against hydrogen sulfide, acetic acid, ammonia, and acetaldehyde. In contrast, Comparative Examples 3 to 5 exhibited poor deodorizing effects against any of hydrogen sulfide, acetic acid, and acetaldehyde.

[0056] Prescription Examples 1-7 Deodorant Composition: Liquid deodorizer compositions were prepared by uniformly mixing all ingredients according to the formulations shown in Table 3 below.
