Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel deodorizing composition, and more particularly to a deodorizing composition with improved persistence, which contains a deodorant extract of a plant as an active ingredient.

It is well known that some plant components have deodorizing effects, and some of them have already been put into practical use as deodorants.

For example, JP-A No. 50-160434 discloses a deodorizing composition for rubber odor-containing rubber odor containing essential oils containing chlorophyll and cedrene compounds, and JP-A No. 58-61751, and Japanese Unexamined Patent Publication No. 59-66 discloses that extracts mainly from the leaves of plants of the Camellia family, such as tea υf1 sakaki and sasanqua, are effective in deodorizing ammonia, trimethylamine, etc., and can be used as a deodorant. Furthermore, JP-A-59-6056 describes that extracts of species of plants belonging to the Lamiaceae family exhibit a deodorizing effect on sulfur compounds.

The mechanism of the deodorizing effect of extracts from these plants is not clear, but it is due to the redox action of porphyrin metal complex compounds such as chlorophyll, or 7-rabone compounds such as 7-labanol and 7-rabonols, or 7-elandrene, It is estimated that the deodorizing effect is produced by the combined effects of inclusion, addition, and neutralization reactions of terpene compounds such as terpinene and pinene, as well as many other polymers.

Deodorants containing extracts from these plants as active ingredients are
There are fewer problems such as chemical damage and environmental pollution (addition to shampoo, hair tonic, soap, toothpaste, mouthwash, etc., for deodorizing rooms and toilets, deodorizing factory exhaust, filter type air cleaner) It is used for purposes such as dexterity, deodorizing wallpaper, and food products such as chewing gum and candy.

However, when these deodorizing ingredients are contained in raw plants, they have advantageous properties such as a longer catalytic life and a faster deodorizing reaction than the first cycle reaction involving coexisting enzymes and air. However, once it is extracted from the plant, the enzyme activity decreases considerably, and the deodorizing reaction and one-cycle reaction are weakened.

The present inventors conducted intensive studies to solve the above-mentioned drawbacks of deodorants whose active ingredients are deodorizing ingredients extracted from plants, and found that L-7 scorbic acid or its derivatives were added to the deodorants. As a result, they discovered that the deodorizing durability of the deodorant was enhanced to make it more comfortable to wear, leading to the completion of the present invention.

Therefore, according to the present invention, L-7 sfulvic acid or a derivative thereof is blended into a deodorant containing a porphyrin metal complex compound, a 7-rabone compound, or a terpene compound as an active ingredient. An excellent deodorizing composition is provided.

A feature of the present invention is that L-7 scorbic acid or a derivative thereof is used in combination with a deodorizing component present in plants.

In the deodorizing composition of the present invention, examples of ingredients that have a deodorizing effect (hereinafter referred to as "deodorizing ingredients") that exist in plants and are used as active ingredients include dog radish. .

(a) Porphyrin metal complex compounds: For example, chlorophyll, chlorophyllin sodium salt, etc.; (b) Flavone compounds: 7 Labones (Example: 7 Labones)
, 7-labonol M (e.g. niltin), iso-7-rabones (e.g. denistein, guisein), 7-rabones (e.g. hesveretin), 7-rabonols (e.g. 7-stin, albinone), etc. Or a mixture of two or more of these.

(c) Terpene compounds: For example, pinene, terpinene, phelandrene, can-7ene, limonene, canonene, pigbolene, campholene, etc., or a mixture of two or more thereof.

These compounds may be pure products, but usually extracts from plants are sufficient.

Further, these compounds may be used alone or in combination of two or more. For example, as a compound containing a large amount of 7-rabone compounds, the above-mentioned JP-A-58-
Extracts of plants of the Camellia family described in Publication No. 61751, such as tea, sasanqua, camellia, sakaki, and hissakaki, mainly from the striations using water, alcohol-based solvents, and ketone-based solvents, or carbonized distillates of these plants are mentioned. Carbonized solutions of needles uI, such as those of Japanese red pine, Japanese cedar, lawson, Japanese cypress, Japanese cypress, and the like, which are already known to contain a large amount of terpene compounds, are suitable.

- On the other hand, derivatives of L-ascorbic acid include 6-desoxy L-7scorbic acid, L-rhamnoascorbic acid, and D-yne 7scorbic acid. , 2, L-7co7scorbic acid, Dike F-gulonic acid, and the like.

The amount of L-7 scorbic acid or its derivatives added to the deodorant component in the deodorizing composition of the present invention is not strictly limited, and depends on the type of deodorant component, the use of the deodorant composition of the present invention, etc. It can vary widely depending on the
Generally, it is appropriate to use L-ascorbic acid or its derivatives in an amount of 1 to 20 parts by weight per 100 parts by weight of the deodorizing component.

The deodorizing composition of the present invention can be attached to or impregnated with a solid carrier such as cloth, cotton, paper, film, plastic foam, microporous inorganic powder (e.g. activated carbon, zeolite, white clay, etc.). It can be in solid form or it can be dissolved or dispersed in a liquid medium. Liquid media that can be used include water, alcoholic solvents (e.g. ethanol, isopropyl alcohol, etc.), ketone solvents (e.g. acetone, methyl ethyl ketone, etc.),
Ether-based solvents (e.g. Ni-diethyl ether, etc.) 1, Ester-based solvents (e.g. ethinoacetate, butyl acetate, etc.), Hydrocarbon-based solvents (e.g., n-hexane, petroleum ether, etc.)
etc. In addition, in order to improve the solubility or fractional stability of the deodorizing component and L-ascorbic acid or its derivatives in these liquid media, a surfactant, particularly a nonionic surfactant, is added to the liquid medium. Can be blended.

Furthermore, when the deodorant composition of the present invention in liquid form is impregnated into the aforementioned fabric or cotton-like material, the deodorant composition in liquid form may be further added with a softener (e.g. fatty acid ester, etc.).
higher alcohols, sulfates) and resins (e.g. melamine resin, glyoxal resin, acrylic ester resin)
etc. may be blended as appropriate.

Therefore, a liquid form of the deodorizing composition may be prepared by using, for example, 0.5 to 4 g of essential oil containing chlorophyll or a 7-rabone compound, and L.
-7 Scorbic acid O,OS~0.88 is diluted with water 500- and optionally 0.1-2 g of non-ionic surfactant such as sodium dodecylbenzenesulfonate, polyethylene glycol sorbicum/stearanthate. can be added to prepare a liquid composition. If necessary, 1 to 10 g of the above-mentioned softening agent/or resin agent may be added and mixed into this liquid composition.

As is clear from the examples below, the deodorizing m-acid of the present invention described above has a much longer lasting deodorizing effect than deodorants that do not contain L-ascorbic acid or its derivatives. As a safe deodorant composition with no worries about drug damage or environmental pollution,
It can be used for deodorization in various industrial fields, including interior interior materials, bed-related products, sanitary electrical materials, sludge treatment, kitchen utensils, and Jμ dual use products.

Next, the present invention will be explained in more detail with reference to Examples.

In addition, the deodorization rate of ammonia or hydrogen sulfide in the examples was determined as follows.
