Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a deodorizing/deodorizing composition that has an extremely excellent effect in removing bad odors even under low temperature conditions such as in a refrigerator, particularly a refrigerator-freezer.

[Background of the invention]

Refrigerators, including freezers, store meat, fish, vegetables, and the like, so various odors are trapped, sometimes forming a bad odor. These bad odors are a complex mixture of fish, meat, vegetable oil, protein decomposition, putrefaction, garlic, etc. Conventionally, such bad odors in the refrigerator have been mainly removed by adsorption using an adsorbent such as activated carbon. It has also been proposed to mask bad odors in refrigerators by using aromatics such as fragrances.

However, the method of adsorbing and removing bad odors using an adsorbent such as activated carbon has the disadvantage that the adsorption capacity of activated carbon is not sufficient and it is difficult to know at what stage the adsorption capacity begins to decrease.

Furthermore, methods for removing bad odors using certain types of fragrances have the disadvantage that the deodorizing effect is not necessarily sufficient and, moreover, toxicity or irritation to living organisms cannot be ignored. Moreover, since the inside of a refrigerator-freezer is at a fairly low temperature, the adsorption capacity of activated carbon or the like may be reduced or the aromatic agent may freeze, resulting in a disadvantage that a sufficient deodorizing effect cannot be achieved.

[Summary of the invention]

The present invention was developed in view of the above circumstances, and is capable of extremely effectively removing bad odors even under low-temperature conditions such as inside refrigerators, including freezers, and is not harmful to humans or animals. It is an object of the present invention to provide a deodorizing composition for a refrigerator, which has extremely low toxicity or irritation, is highly safe, and whose malodor removal effect does not deteriorate even at considerably low temperatures.

The deodorizing and deodorizing composition according to the present invention, which is particularly suitable for use under low temperature conditions such as refrigerators, is composed of cinnamon oil or synthetic cinnamon oil having a composition similar to cinnamon oil, polyethylene glycol having a molecular weight of up to 600, and a lower alcohol. or water or a mixture thereof, and optionally contains a small amount of acid such as malic acid, maleic acid, humic acid, succinic acid, citric acid, or acetic acid.

[Specific description of the invention]

The first essential ingredient in the present invention is cinnamon oil (cinnamon oil) or synthetic cinnamon oil with a composition similar to cinnamon oil. Cinnamon oil is a yellow perfume oil obtained by distilling the bark of various types of daylily, especially Ceylon daylight or Chinese daylight.The main component is cinnamic aldehyde, with small amounts of cinnamic acid, cinnamic acid ester, cinnamic alcohol, etc. include. Instead of cinnamon oil obtained by distillation of daylily bark, mixtures of cinnamic aldehydes, cinnamic acids, cinnamic esters, and cinnamic alcohols, either synthesized or isolated from natural sources, can also be used. . The proportions of cinnamaldehyde, cinnamic acid, cinnamic acid ester, and cinnamic alcohol in this mixture can vary widely compared to natural cinnamon oil.

In the deodorant composition, the amount of cinnamon oil or synthetic cinnamon oil is 20% by weight or less, preferably 3 to 1% by weight of the composition.
It is present in an amount of 5% by weight, more preferably 5-10% by weight.

The second essential component in the present invention is polyethylene glycol. Polyethylene glycol changes into liquid, semi-solid, waxy, and solid as its molecular weight increases, but in the present invention, liquid and semi-solid polyethylene glycol is used, and polyethylene glycol in such a state has a molecular weight of about 600 or less.

The polyethylene glycol is present in the deodorant composition in an amount of 10 to 70%, preferably 20 to 60%, more preferably 30 to 50% by weight of the composition.

The third essential component in the present invention is a lower alcohol, water, or a mixture thereof. The lower alcohol means an alcohol having 1 to 5 carbon atoms, and specifically includes methanol, ethanol, n-propanol, isopropanol, n-butanol, tert-butanol, and the like. Among these, ethanol is sometimes preferred.

In the deodorant composition, the lower alcohol or water or a mixture thereof is contained in an amount of 10 to 60% by weight based on the weight of the composition;
Preferably 20 to 50% by weight, more preferably 30 to 50% by weight
Present in an amount of 50% by weight.

When using a deodorant composition in a considerably low temperature state such as a refrigerator-freezer, it is necessary to use only a lower alcohol (however, the presence of a small amount of water is permissible) as the third essential component. On the other hand, when the deodorizing composition is used in the refrigerator or kitchen without being used in the freezer, a mixture of lower alcohol and water or water can be used.

In short, the third essential component can be varied depending on the temperature of the surrounding environment in which the deodorant composition is used.

It is desirable to further include a small amount of acid in the deodorant composition of the present invention, if necessary, to adjust the pH to 5.0 or less, preferably 3.0 to 4.0. By adjusting the pH of the deodorant composition, the deodorizing effect can be enhanced. Examples of acids to be included in the deodorant composition include malic acid, maleic acid, humic acid, succinic acid, citric acid,
Organic acids such as acetic acid are used. Among these, malic acid, succinic acid, and citric acid are particularly preferred.

In the present invention, by further adding chlorophyll, colorants, fragrances, antioxidants, etc. as necessary,
Product value can be increased.

The deodorant composition of the present invention contains cinnamon oil or synthetic cinnamon oil having a composition similar to cinnamon oil.
It is produced by adding and mixing polyethylene glycol having a molecular weight of up to 0.00, and adding and mixing a lower alcohol or water or a mixture thereof to this mixture. In addition, if necessary, add a small amount of acid or chlorophyll.
Colorants, fragrances, antioxidants, etc. can be added and mixed.

When producing a deodorizing composition, adding polyethylene glycol after adding and mixing cinnamon oil or synthetic cinnamon oil having a composition similar to cinnamon oil to a lower alcohol, water, or a mixture thereof causes phase separation. This is not preferable because a phenomenon is observed.

All of the components used in the deodorizing and deodorizing composition of the present invention are safe for living organisms such as the human body, and even when used under low temperature conditions, they do not freeze and exhibit sufficient deodorizing effects. It has the characteristic of

The deodorizing composition according to the present invention has particularly excellent deodorizing and deodorizing effects when used in environments kept under low-temperature conditions such as refrigerators and freezers, but it also shows excellent deodorizing effects when used at room temperature. It is recognized for its deodorizing and deodorizing effects, and can be used in car interiors, bathrooms, toilets, kitchens, etc.

The present invention will be explained below using examples, but the present invention is not limited to the examples.

Example 1 8 parts by weight of cinnamon oil containing cinnamic aldehyde, cinnamic acid, cinnamic acid ester, and cinnamic alcohol were added to
The mixture was added to and mixed with 60 parts by weight of liquid polyethylene glycol having a concentration of 0. Next, 32 parts by weight of ethanol was added to this mixture and thoroughly mixed to produce a deodorizing composition for refrigerators and freezers.

When this deodorant composition was placed in a commercial large-sized refrigerator-freezer maintained at -20°C, it was observed that it had the effect of weakening the odor in the freezer.

Example 2 Synthetic cinnamon oil was prepared by mixing appropriate amounts of synthesized cinnamic aldehyde, cinnamic acid, cinnamic acid ester, and cinnamic alcohol. Five parts by weight of this synthetic cinnamon oil were added and mixed with 55 parts by weight of liquid polyethylene glycol having a molecular weight of 250. Next, 30 parts by weight of ethanol and 9 parts by weight of water were added and mixed to this mixture, and further 0.5 parts by weight of malic acid was added and thoroughly mixed to produce a deodorizing composition for a refrigerator.

When this deodorant composition was placed in a household refrigerator kept at about 5° C. in which meat, fish, and minced garlic were stored, it was observed that it had the effect of weakening the odor inside the refrigerator.

Example 3 10 parts by weight of cinnamon oil containing cinnamic aldehyde, cinnamic acid, cinnamic acid ester, and cinnamic alcohol were added to
The mixture was added to and mixed with 55 parts by weight of liquid polyethylene glycol having the following properties. Next, 34.5 parts by weight of water was gradually added and mixed to this mixture, and further 0.5 parts by weight of citric acid was added and thoroughly mixed to produce a general-use deodorizing composition.
