Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solid deodorizing and aromatic composition having both deodorizing and fragrance generating functions.

Conventionally, deodorants have been made using activated carbon, which utilizes its adsorption effect, or products in which vaporized deodorizing liquid is adsorbed onto a solid adsorption carrier, and as air fresheners, fragrances have been solidified in the form of agar. So-called gel-type fragrances are common. While the former type of deodorant is characterized by its ability to eliminate odors without adding fragrance, it is difficult to confirm its effectiveness and end point, while the latter type of air freshener eliminates bad odors by masking or neutralizing them with scent. It only makes it less perceivable to the sense of smell.
It has the disadvantage that it does not have the ability to actively act on malodorous substances to make them odorless. However, the current products that call themselves solid deodorants and air fresheners are mostly solid air fresheners that make it difficult to detect bad odors.On the other hand, products that don't rely on fragrance and call themselves deodorants are products such as activated carbon, for example. Even if it is not attached, or if it is scented, it will only have the effect of giving a slight fragrance.

An object of the present invention is to provide a new solid deodorizing fragrance composition that actively oxidizes and decomposes malodorous substances and also has the function of generating a fragrance similar to that of conventional fragrances.

The present inventor has previously developed a "chlorine dioxide volatilization composition" (
Japanese Patent Application No. 56-054804) is useful as a solid deodorant, and furthermore, an aromatic composition in which a perfume liquid is adsorbed onto a synthetic calcium silicate molded product (Japanese Patent Application No. 117229-1982) is useful as a solid deodorant.
It was found that the product (No. 1) is superior to conventional products as a solid fragrance.

The present inventor, who has been diligently developing solid deodorizing and aromatic agents that decompose bad odors and provide fragrance, naturally developed two types of adsorbents (stabilized chlorine dioxide liquid adsorbent and fragrance adsorbent) in the earlier application. It has been found that a mixture of these substances is useful as a solid deodorizing fragrance.

On the other hand, it is well known in the industry that it is impossible to use stabilized chlorine dioxide liquid in liquid form with a fragrance mixed therein due to its oxidizing action.

Therefore, it has never been attempted to adsorb both a stabilized chlorine dioxide solution and a fragrance into a solid adsorption carrier, but surprisingly, this has been achieved by using synthetic calcium silicate as an adsorption carrier. The present inventors have discovered that an adsorbent obtained by adsorbing a stabilized chlorine dioxide solution and a perfume has a scent that is almost unchanged compared to the base perfume, and has the property of gradually volatilizing the chlorine dioxide.

Furthermore, as a result of many studies, we have found that synthetic calcium silicate has a higher adsorption capacity than the case where stabilized chlorine dioxide solution and fragrance are adsorbed on synthetic calcium silicate separately. It was discovered that the adsorbent in which both liquids are adsorbed to calcium has a longer fragrance retention life. In other words, compared to the case where the adsorbent of the stabilized chlorine dioxide solution and the adsorbent of the fragrance were adjusted and mixed,
The present invention was completed based on the discovery that an adsorbent in which both liquids are adsorbed together has a synergistic effect in that the aroma retention property is superior. In this way, it is completely unexpected that the adsorbent that adsorbed two types of liquids exhibited a synergistic effect that was completely unexpected from the properties of the mixture of adsorbates that were adsorbed individually. That's what I decided.

The reason for this synergistic effect has not yet been theoretically explained, but the coexistence of the fragrance and the stabilized chlorine dioxide solution in the absorption carrier causes a change in synergy due to an increase in the point. It is also speculated that the stabilizer in the stabilized chlorine dioxide solution (containing 5% by weight in the solution) contributes to retaining its volatility.

To explain the present invention in more detail, the synthetic calcium silicate used in the present invention includes calcium silicate having a large adsorption capacity.
For example, synthetic calcium silicate is used which can absorb at least 50% by weight of liquid, preferably 100 to 300% by weight. Furthermore, the surface area of the synthetic calcium silicate powder is 90 m2/g or more, preferably about 100 to 150 m2/g.
A range of m2/g is desirable.

Trace amounts of iron compounds in the synthetic calcium silicate cause deterioration of the adsorbed fragrance and stabilized chlorine dioxide solution over time, so they must be limited to 0.2% by weight or less as Fe2O3. The inventor has previously discovered that when a fragrance is adsorbed onto synthetic calcium silicate, the pH of the synthetic calcium silicate is in the neutral to weakly basic range, which has little effect on the aging properties of the fragrance. (Patent application 117229/1982)
No.), P of the synthetic calcium silicate used also in the present invention
It is desirable that H is in the range of 7.6 to 9.4, preferably 7.6 to 8.8. In addition, when a molded product is used as an adsorption carrier in the present invention, powdered cellulose such as crystalline cellulose or hydroxypropyl cellulose is added in an amount of 1 to 30% by weight based on synthetic calcium silicate in order to improve the strength and fragrance retention of the molded product. It is preferable to use the mixture in the following proportions.

The honorific names of the synthetic calcium silicate used are powdered,
Although any molded product can be used, it is preferable to use a molded product because the above-mentioned improvement in fragrance retention is more remarkable in the molded product.

Next, the stabilized chlorine dioxide solution used in the present invention has a concentration of 100 to 50,000 ppm, preferably 1,000 to 50,000 ppm, from the viewpoint of deodorizing effect.

Further, as the perfume to be used, any liquid perfume can be used regardless of its composition and concentration.

In the present invention, adsorption of these two types of liquids onto synthetic calcium silicate is achieved by stirring the liquids while spraying or dropping them onto the synthetic calcium silicate. The adsorption order is as follows: If the fragrance is adsorbed first, stabilization may occur depending on the composition of the fragrance or the amount of adsorption.As the chlorine dioxide solution is adsorbed, the fragrance may come out onto the surface of the carrier. The preferred order is to adsorb the chlorine dioxide solution and then adsorb the fragrance.

The adsorption amount ratio of the stabilized chlorine dioxide solution and the fragrance to the synthetic calcium silicate is in the range of 1:100 to 100:1, preferably 1:10 to 10:1 in terms of weight ratio. At this time, the total adsorption amount of both liquids is not particularly limited as long as it is within the adsorption capacity of synthetic calcium silicate. It is preferable to adsorb a total of 10 parts by weight or more.

The deodorizing aromatic composition of the present invention has the effect of decomposing bad odors, particularly bad odors originating from sulfides, amines, phenols, etc., by sulfurization using chlorine dioxide that is gradually volatilized, and also has the effect of imparting aromas from fragrances. The dots are said to be a major feature not seen in conventional products. Therefore, deodorizing air fresheners for cars, toilets, etc., indoor air fresheners shaped like animals, dolls, etc., deodorant air fresheners that can be set in the air intake or outlet of air conditioners, printing inks, plastics, rubber, etc. It can be used as a filler in materials that impart deodorizing aromas, etc., and has great effects.

Examples are shown below, and all parts and percentages are by weight.

I got the composition. When this tablet was stored in a plastic frame with a clip to attach it to the rectifying plate of the air outlet and used outside of a car, the deodorizing and fragrance effect was observed for about 40 days.

Example 2 To 100 parts of a 3-4 m/m medium spherical molded product of synthetic calcium silicate with an iron compound content of 0.03% as Fe2O3 (trade name Fluorite-R-Marume, manufactured by Tokuyama ■Tatsu), 5
,000 ppm stabilized chlorine dioxide solution and 50 parts of Chanel #19 type fragrance were adsorbed to obtain a deodorizing fragrance composition of the present invention. When 60 parts of this was placed in a breathable container and used in the toilet, it remained effective for about 45 days.

As a comparative example, 80 parts of 5 was added to 100 parts of the above molded article carrier.
,000ppm stabilized chlorine dioxide solution adsorbed only, and an adsorbed material in which only 50 parts of Chanel #19 type fragrance was adsorbed on 100 parts of a molded article carrier were prepared, and 30 parts of each of these adsorbed materials were prepared. If 60 copies of the mixture were left in the toilet under the same conditions as above, 30 to 3
It was only valid for 5 days.

In other words, the adsorbent obtained by adsorbing both the stabilized chlorine dioxide solution and the fragrance with the same adsorption amount has a longer effective life as a deodorizing fragrance than a mixture of adsorbents adsorbed separately. I got it.

When sprayed in advance on the bottom of a polyethylene garbage bag placed in a sealed plastic trash can and then thrown in with kitchen garbage, the deodorizing effect was observed for 5 to 6 days until the bag was full. .

Example 5 Granular synthetic calcium silicate (
100 parts of 1,000 ppm stabilized chlorine dioxide solution and then 1 part of lavender fragrance were adsorbed onto 100 parts of Fluorite R (trade name: Tokuyama ■Datsu Co., Ltd.).

When 20 parts of the thus obtained deodorizing aromatic composition of the present invention was uniformly placed in a sandwich-like manner in a shoe insole made of felt and saran, it exhibited a deodorizing effect for about one month against stuffy odors in shoes. .

Example 6 100 parts of synthetic calcium silicate used in Example 1
The deodorizing aromatic composition of the present invention obtained by sequentially adsorbing 20 parts of ppm stabilized chlorine dioxide and 100 parts of Chanel #19 type fragrance was mixed into printing ink at 5 to 10% and printed on paper by a conventional method.
