Description
DEODORIZING AGENTS CONTAINING PLANT
EXTRACTS AS THE EFFECTIVE INGREDIENT
The present invention concerns a deodorizing agent containing a plant extract as an effective ingredient thereof. More particularly, the present invention provides various forms of deodorizing agent containing at least one component selected from plant extracts of the leaves of oak, that is, Quercus dentata Thunb, Quercus dentata Thunb var.
erectrospuamasa Nakai, Quercus dentata Thunb var. glandifolia Koidzuki and
Quercus dentata Thunb var. fallax Nakai; leaves of persimmon1 that is
Disopyros kaki L. F.; and whole grass of Isodon japonicus Hara and Isodon glaucocalyx (Maxim.) Kado, as an effective ingredient thereof.
Various offensive odors are generated by industry such as factories and by living zones, such as homes and offices, and this has lead to research into providing efficient deodorizers which can eliminate offensive odors, in order to produce more pleasant living environments.
Until now, physical and chemical treatment methods have been employed to eliminate various objectionable odors.
Water-rinsing, cooling, and adsorption methods are examples of physical deodorizing methods. Generally, water-rinsing and cooling methods are rarely employed since large amounts of water and large-scale apparatus are necessary to operate these methods. Adsorption methods using the adsorption power of adsorbents such as active carbon have the disadvantage that the offensive odors are released back from the absorbent after adsorption thereof.
Chemical agent treatments and masking methods are examples of chemical deodorizing methods. Chemical agent treatments are effected by acid or alkali washing to deodorize offensive odors, but the odors which can be eliminated by this method are restricted and moreover, caution is required in handling these agents. It is another disadvantage that large-scale apparatus is required for this method. Masking methods achieve a deodorizing effect by masking offensive odors with the fragrance of the deodorizer itself. However, the very fragrance of deodorizer is often offensive to the consumer and further, the problem is that the offensive odors cannot be basically eliminated by this method.
Several deodorizing agents which can eliminate offensive odors in a simple and effective way have been developed and marketed. But the odors which can be eliminated by these deodorizers are limited and there is a significant problem that the deodorizer components may be toxic to humans, since most of the effective ingredients of these deodorizers are artificially synthesized compounds.
Accordingly, numerous studies for providing safe deodorizers containing natural substances are actively underway.
Japanese Examined Patent Publication 9141457 proposes a deodorizing agent comprising juice of immature persimmon compressed by a compressor, juice deprived of sugar components by fermenting the said juice for about six months during which the juice is stored in a sealed state, or dehydrated concentrate obtained by dehydrating the said juice under reduced pressure and formulating with adjuvant.
Although both safety and good deodorizing effect are achieved by the aforementioned deodorizing agents, their preparation is somewhat complex and time consuming. In particular, it is a serious problem that large amounts of other components than the deodorizing component are included in the
resultant deodorizing agent, since the compression is operated by a compressor and additionally, due to the color originating from the juice
itself, its use against various offensive odors is limited. Another problem
is that the formulation thereof is difficult.
The present inventors have carried out intensive research to develop a deodorizing agent to solve the aforementioned problems and found that a deodorizing agent containing as an effective ingredient, at least one component selected from plant extracts of the leaves of Quercus dentata Thunb, Quercus dentata Thunb var. erectrosquamasa Nakai, Quercus dentata Thunb var. glandifolia Koidzuki and Quercus dentata Thunb var. fallax
Nakai; leaves of Disopyros kaki L. F.; and whole grass of Isodon japonicus Hara and lsodon glaucocalyx (Maxim.) Kado, extracted by extracting solvent, as an
effective ingredient, has excellent deodorizing capability. These plants are edible and thus have long been used as food material in Korea, China and
Japan. Measurement of its deodorizing power reveals that the deodorizing agent according to the present invention has excellent deodorizing effects.
The composition of the present invention is safe and can be prepared economically.
An aim of the present inventors was thus to provide a safe deodorizing agent exhibiting excellent deodorizing effects for various objectionable odors which can be prepared by a simple and economic process.
Another aim of the present inventors was to provide a deodorizing agent having various formulations and discoloration degree, which are suitable for diverse purposes, usages and product forms, according to the consumer's requirement.
In accordance with the present invention, there is provided a deodorizing agent containing as an effective ingredient, at least one component selected from the group consisting of the plant extracts of the leaves of Quercus dentata
Thunb, Quercus dentata Thunb var. erectrosquamasa Nakai, Quercus dentata
Thunb var. glandifolia Koidzuki and Quercus dentata Thunb var. fallax Nakai; leaves of Disopyros kaki L. F.; and whole grass of Isodon japonicus Hara and
Isodon glaucocalyx (Maxim.) Kado, as an effective ingredient The extract may be extracted with an extraction solvent.
The invention will now be described in more detail with reference to specific embodiments thereof.
Water or a mixture of water and hydrophilic organic solvent, such as methanol and ethanol, is an example of an extraction solvent employed in extracting the above-mentioned plant extracts.
The aforementioned plants can be subjected to rinsing, drying and crushing, if necessary. Optionally, a pre-treatment for decolorisation of the plant by adding an extraction solvent such as water or a mixture of water and methanol or ethanol can be additionally performed. In this case, the deodorizing agent is preferably prepared by addition of a phosphate salt such as dibasic sodium phosphate and calcium chloride to the plant extracts and filtration.
Besides the aforementioned solvent extraction pre-treatment, various methods can be used to provide decolorised deodorizing agent. For example, a method wherein active carbon or activated charcoal is added to the plant extracts followed by filtration or a method using an ion exchange resin or an adsorption resin column is preferably employed.
The liquid extracts obtained by the aforementioned process can be employed as such, as a deodorizing agent.
However, the deodorizing agent of the present invention can be formulated into various forms such as a spray type, a gel type, or a granule type. A spray type deodorizing agent can be prepared by adding water, and polyvalent alcohol such as propyleneglycol for an anti-scattering or preserving effect and organic acid such as citric acid for enhancing the deodorizing effect against nitrogen-based odors, or a small amount of fragrance into the aforementioned plant extracts. A gel type deodorizing agent may be prepared by addition of gelling agent to the aforementioned plant extracts and a granular deodorizing agent may be prepared by adding a porous carrier such as active carbon and bentonite to the aforementioned plant extracts.
A better understanding of the present invention may be obtained in light of following examples which are set forth to illustrate, but are not to be construed to limit the present invention.
