Abstract

PROBLEM TO BE SOLVED: To inhibit the generation of offensive odor from excrements of a human being or the like by arranging a β-cyclodextrin clathrate perfume and an adsorptive powder material to be contained into a deodorant. SOLUTION: β-cyclodextrin clathrate perfume obtained by inclusion of a perfume into β-cyclodextrin and adsorptive powder material such as activated carbon or kaoline are contained to form a composition for inhibiting offensive small. The adsorptive powder material herein used is preferably silicic anhydride, zinc oxide or bentonite and may be a combination of more than one thereof. The mixing ratio of the β-cyclodextrin clathrate perfume and the adsorptive powder material should be 0.1:100-5:100 and moreover, preferably about 0.3: about 100 to about 2: about 100. The perfume to be included into the β- cyclodextrin employs methyl salicylate or the like. Moreover, non-adsorptive or less adsorptive material such as nylon powder may be contained as an arbitrary component.

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a composition for suppressing offensive odors suitable for sanitary goods and pet goods.

[0002]

2. Description of the Related Art As life expectancy has increased in recent years, modern society has begun to move toward an aging society. In such a situation, the importance of sanitary articles such as disposable diapers is increasing. In many cases, such hygiene articles are applied to elderly people by changing the size of products originally developed for infants. Old people and infants have very different types of food and their metabolic systems,
There are problems such as generation of off-flavors. Although masking with a fragrance or the like has some effect depending on the fragrance component, it is often short-lived and only a temporary measure. On the other hand, a method of encapsulating a perfume in β-cyclodextrin or the like and masking the offensive odor while suppressing the generation of the offensive odor by exchanging the offensive odor component with the perfume was devised, but the offensive odor component was β- Since it was difficult to be included in cyclodextrin, and even if the fragrance by sustained release could improve the persistence, the masking effect was often impaired, and the desired effect was not obtained. That is, there has been a demand for means for suppressing such an offensive odor. Further, it has not been known at all that adsorptive powders such as activated carbon, kaolin, silicic acid anhydride, zinc oxide and bentonite excel in trapping offensive odors.

With regard to the generation of offensive odors, pets, which have become popular in recent years, are similarly problematic due to their excrement and body odor, and various toilets for pets have been devised. Although toilets that prevent urine from leaking out have been made by applying technologies such as water-absorbing polymers, pet toilets that suppress odors have not yet been obtained.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such a situation, and an object thereof is to provide means for suppressing the generation of offensive odor caused by human or pet excrement. .

[0005]

SUMMARY OF THE INVENTION In view of such circumstances, the inventors of the present invention have conducted intensive studies in search of a means for suppressing an offensive odor, and as a result, have found that a β-cyclodextrin inclusion perfume and an adsorptive powder can be obtained. It has been found that the composition containing the compound has an excellent effect of absorbing and masking offensive odors, and that when such a composition is used for sanitary products such as paper diapers and pet products, the occurrence of offensive odors due to these can be prevented. Completed Hereinafter, the present invention will be described in detail focusing on its embodiments.

(2) Adsorbent powder used in the present invention The adsorbent powder used in the present invention can be used without particular limitation as long as it has a high adsorptive capacity. Examples thereof include activated carbon, kaolin, silicic acid anhydride, zinc oxide, bentonite, etc. Among them, silicic acid anhydride and activated carbon are particularly preferable. These powders may be used alone or in combination of two or more.
These adsorptive powders have a function of holding an offensive odor component or a component causing an offensive odor so as not to vaporize.

(3) Composition for controlling offensive odor of the present invention The composition for suppressing offensive odor of the present invention is characterized by containing the above-mentioned β-cyclodextrin inclusion perfume and an adsorptive powder. In the composition of the present invention, the preferable ratio of the β-cyclodextrin clathrate and the adsorptive powder is 0.
1: 100 to 5: 100, more preferably 0.
3: 100 to 2: 100, more preferably 0.
It is 5: 100 to 1: 100. In addition to these, the composition of the present invention has, as an optional component, a powder having no or very low adsorbability such as β-cyclodextrin or nylon powder and / or a superabsorbent polymer such as an acrylic polymer or slush. It may contain a water-absorbing substance such as cellulose such as pulp. The preferred content of these optional components in the composition of the present invention is 10 to 50% by weight based on the total weight of the composition.

(4) Scope of application of the present invention The composition of the present invention can be used for products having an offensive odor without particular limitation. As such a product, for example,
Examples include human diaper products such as paper diapers, sanitary sheets, and simple toilets, pet products such as bedding, pet toilets, and pet sheets. Other examples include deodorant powder and toiletry products that suppress the generation of offensive odors such as toilets by sprinkling raw garbage or animal excrement to suppress the generation of foreign substances. or,
Since the components are widely used in cosmetics and the like, they can be blended in cosmetics such as deodorant and skin external preparations such as athlete's foot medicine. The composition of the present invention can be produced by a usual method such as a usual method for producing a powder composition. For example, in the case of a powder composition, it may be uniformly mixed with a Henschel mixer or the like and crushed with a palberather, etc., and in the case of a semi-solid composition, it may be mixed with a roll or a kneader. The composition thus obtained has an excellent effect of suppressing an offensive odor due to the synergistic effect of suppressing the generation of an offensive odor by the adsorptive powder and the persistent masking by the β-cyclodextrin inclusion fragrance.

[0023]

EXAMPLES The present invention will be described in detail below with reference to Examples, but it goes without saying that the present invention is not limited to these Examples.

Example 1 Production Examples 1 to 4 and Odor Control Effect The composition of the present invention was prepared according to the formulation shown in Table 1 by changing the kind of the adsorptive powder. The amount of powder was 0.5 g, and 0.05 g of β-cyclodextrin inclusion flavor 1 was used as the β-cyclodextrin inclusion flavor. These were manufactured by mixing well in a mortar. To this, 35 ml of human urine was added, and the standing condition of the offensive odor was judged by 5 professional panelists immediately after adding human urine and 1 hour after adding it, with 5 points that dissimilar odors are not a concern and 1 point that a strange odor is extremely anxious. Then, the average value was obtained. Control 1 has neither adsorbable powder nor β-cyclodextrin inclusion fragrance added, Control 2 does not contain adsorbable powder, Control 3 has β-cyclodextrin inclusion fragrance 1 from Production Example 1 β-
Substituted with cyclodextrin, Comparative 1 is substituted with 0.005 g of methyl salicylate for the β-cyclodextrin inclusion flavor of Production Example 1, and Comparative 2 is Production Example 1
The kaolin was replaced with calcium carbonate.
From this, it is understood that the composition of the present invention has an excellent effect of suppressing offensive odor, and that this effect is a synergistic effect of the adsorptive powder and the β-cyclodextrin inclusion flavoring agent. Further, it can be seen that kaolin and silica gel are particularly excellent as the adsorptive powder.

[0025]

[Table 1]

Example 2 Production Examples 5 to 16 As in Example 1, 0.5 g of kaolin was added to 0.05 g of β-cyclodextrin clathrate to prepare a composition,
Similarly, the effect of suppressing offensive odor was examined. Table 2 shows the results.
