TECHNICAL FIELD The present invention relates to an iodine germicidal deodorant composition having excellent long-term storage stability.

[0002]

2. Description of the Related Art Iodine is widely used as a bactericide because it has low toxicity to the human body and excellent bactericidal activity, but it has poor stability in an aqueous solution, and iodine is decomposed and sterilized when stored for a long time. The power decreases. Therefore,
It has been proposed to maintain the stability of the iodine fungicide by blending iodine at a high concentration or using a high concentration alcohol as a solvent (Japanese Patent Laid-Open No. 15690/1989).
4 and JP-A 1-294606).

On the other hand, although these iodine-based bactericides have bactericidal ability, they do not have deodorant ability, and normally, when these bactericidal agents are used, odors are generated by microorganisms.
Iodine-based germicides are required to have deodorizing ability as well as sterilizing ability. However, no fungicide composition having excellent deodorizing power has been proposed so far.

In view of such circumstances, by blending an iodine-based bactericide and a plant extract as a deodorant, a bactericidal composition having excellent bactericidal activity, deodorizing power and long-term stability. Various studies were conducted for the purpose of obtaining As described above, in order to maintain the bactericidal power of iodine sufficiently and to have long-term stability, it is necessary to use a high-concentration alcohol as a solvent, but when a plant extract is added to such a solvent system, turbidity or precipitation occurs. Therefore, there is a problem that a stable system cannot be obtained, or iodine is decomposed to reduce the bactericidal effect.

However, the present inventors have surprisingly found that a specific plant dry distillation extract has a bactericidal effect in an iodine fungicide,
They have found that they exhibit an excellent deodorizing effect without impairing long-term stability, and have completed the present invention.

That is, the present invention relates to (1) (a) 80% by weight of 1 to 10 carbon atoms based on the total amount of the composition.
3 lower alcohol or (b) the lower alcohol,
A sterilizing composition containing a mixture with at least one compound selected from polyols and polyol derivatives, (2) 0.005 to 5% by weight of povidone iodine, and (3) 0.01 to 2.0% by weight of green tea dry distillation extract. An odor composition is provided.

Examples of the lower alcohol having 1 to 3 carbon atoms used in the present invention include methanol, ethanol, propanol and isopropanol. Particularly, ethanol is preferable.

Examples of the polyol used in the present invention include ethylene glycol, propylene glycol and 1,3-butylene glycol, and examples of the polyol derivative include ethylene glycol monoalkyl ether and diethylene glycol monoalkyl ether.
Examples include propylene glycol monoalkyl ether, dipropylene glycol monoalkyl ether, and acetates thereof. These polyols or polyol derivatives may be used alone or in combination of two or more.

When a mixture of a lower alcohol having 1 to 3 carbon atoms and at least one compound selected from polyols and polyol derivatives is used, the compounding amount of at least one compound selected from polyols and polyol derivatives is It is preferably 20% by weight or less based on the total amount.

The povidone iodine used in the present invention includes:
For example, PVP-IODINE30 / 06 (manufactured by BASF), PVP-Iodine10 (manufactured by GAF), and the like are included, and the compounding amount thereof is 0.005 (effective iodine concentration 5 ppm) to 5.0 with respect to the total amount of the composition. Weight% (effective iodine concentration 5000 ppm), preferably 0.05% by weight (effective iodine concentration 50 ppm) to 0.2% by weight (effective iodine concentration 200 ppm). 0.005% by weight
If the amount is less than that, the stability of iodine is poor and the bactericidal power is not sufficiently exhibited, and if it exceeds 5.0% by weight, problems occur such that the color of the composition is too dark and the object is discolored.

In the present invention, green tea dry distillation extract is used as a deodorant. 20% of dried green tea leaves
Hg, heated at 180 ° C. under reduced pressure, cooled to collect fractions, filtered and purified, and is commercially available.
S-500A (manufactured by Shiramatsu Shinyaku Co., Ltd.) can be used.
The blending amount is 0.01 to 2.0% by weight as an extract,
It is preferably 0.05 to 1.0% by weight. If the blending amount is less than 0.01% by weight, sufficient deodorizing power is not exhibited, and if it is more than 2.0% by weight, the deodorizing effect is not improved and it is uneconomical.

The iodine-based germicidal deodorant composition of the present invention can be in the form of a solution, gel, paste, solid or the like, and can be obtained by mixing desired components and stirring by a conventional method. Further, if necessary, the iodine-based germicidal deodorant composition of the present invention, as long as the stability of iodine is not impaired, further, an organic acid or a salt thereof, a surfactant, a fragrance,
Additives such as colorants and polymers can be appropriately added.

The germicidal deodorant composition of the present invention can be used as a germicidal deodorant for home or business use for sterilizing and deodorizing shoes, toilets, garbage and the like.
