BACKGROUND OF THE INVENTION
The present invention relates to a deodorant effective for deodorizing ammonia, amines, hydrogen sulfide and mercaptans, and more specifically, ammonia, amines, hydrogen sulfide and The present invention relates to a deodorant effective for deodorizing mercaptans.
[0002]
[Prior art]
In general, nitrogen compounds such as ammonia and amines, and sulfur compounds such as hydrogen sulfide and mercaptans are known as bad odor sources. For example, odors from toilets and kitchens at home, pet odors, and tobacco odors generated when smoking are caused by the presence of trace amounts of ammonia, amines, hydrogen sulfide and mercaptans. The odor causes discomfort and headaches.
[0003]
Methods for deodorizing such malodors have been studied in the past. For example, 1) a method of masking malodors with a strong aroma component, and 2) malodorous components by activated carbon, zeolite, cyclodextrin, etc. Method of physically deodorizing by adsorption, inclusion, 3) Method of deodorizing malodorous components by chemical neutralization, oxidation, condensation, etc. 4) Method of biological deodorization using microorganisms such as activated sludge , Etc. have been proposed.
[0004]
However, the masking method does not always have a strong fragrance component that is comfortable for the user, and has a disadvantage that it may become a bad odor reminiscent of a toilet odor. Further, the method of adsorbing malodorous components on activated carbon or the like has drawbacks such that the effect is lost when the adsorbent becomes saturated.
[0005]
Therefore, deodorizing effects can be expected by chemically reacting with malodorous substances and changing them to odorless chemical substances, and the development of deodorants derived from natural products that are safe for the human body has been studied. Since ancient times, it has been practiced to plant a southern sky tree on the side of the toilet, but this was the wisdom of life using the deodorizing action of the southern sky tree. There is also a proposal of a deodorant that has actually been found to have a deodorizing effect on an extract from the southern sky (Japanese Patent Laid-Open No. 61-143066). Many have been proposed.
[0006]
Among them, as a deodorant that removes ammonia odor and amine odor, for example, a deodorant that uses an extract from kathami, sasanqua, tsutsuga, crape myrtle, nanten, chestnut, sunkazura, mizume, nishikimatsu, ginkgo ( Japanese Patent Laid-Open No. 61-103447), a deodorant containing an extract such as murasaki kabami and dokudami as an active ingredient (Japanese Patent Laid-Open No. 61-143066), and a deodorant using an extract of a red crustacean plant ( JP-A-1-284257), deodorizers (JP-A-3-264070) and the like, which contain extracts of rose, leguminous, pine, and magnoliaceae plants as active ingredients, have been proposed. Examples of the deodorant for hydrogen sulfide or mercaptan odor include, for example, a method for producing a deodorant substance using a Lamiaceae plant (Japanese Patent Laid-Open No. 57-204278), an extract such as Kiri, Lilac, and Sinalengo. Deodorant as an active ingredient (Japanese Patent Laid-Open No. 61-94660), sulfur-based malodorous substance selective deodorant (Japanese Patent Laid-Open No. 1-218457) containing an extract of Dansang or Lamiaceae as an active ingredient, A method for producing a deodorant containing, as an active ingredient, an extract of a red plant family, cedar family, azalea family, or citrus family plant has been proposed (JP-A-3-261479).
[0007]
However, these proposals separate and purify the deodorant active ingredient from the plant body as a raw material by a number of processes, and the obtained deodorant becomes quite expensive, which is not necessarily industrially advantageous. Some are not. Therefore, there has been a demand for a deodorant that has a deodorizing effect specifically for ammonia, amines, hydrogen sulfide, and mercaptans, which is easily available, relatively inexpensive, and industrially advantageous.
[0008]
[Means for Solving the Problems]
Therefore, the present inventors have conducted intensive research in order to solve the above problems. As a result, it was quite unexpected that amylis oil used as a flavoring ingredient in cosmetics and fragrances such as cosmetics was added to ammonia, amines, hydrogen sulfide and mercaptans. Thus, the present invention was completed by finding that it has a deodorizing effect equivalent to or higher than that of the above-mentioned conventional deodorants. That is, the amylis oil is a very inexpensive fragrance raw material obtained by steam distillation from raw wood of Amyris balsamifera of the citrus family that grows in the northern part of South America and the like, and is used for amines and mercaptans. On the other hand, the specific deodorizing effect has not been described or suggested in the conventional literature, and examples of use as a deodorant are not known.
[0009]
Specific embodiments of the present invention will be described below.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
The product of the present invention is a deodorant characterized by containing amiris oil as an active ingredient, and is an effective deodorant for deodorizing ammonia, amines, hydrogen sulfide and mercaptans.
[0011]
Amyris oil, which is an active ingredient of the present invention, is obtained by steam-distilling raw wood chips or sawdust-like raw materials of the citrus family Amyris balsamifera that grows in the North, Central America and West Indies of South America. And is obtained by separating the water from the distillate oil. Since sesquiterpene is the main component and has an incense of sandalwood and wood, it is often used as a mild fragrance. It is widely available in the market. I. Company C, G. It is easily available from UHE. Ordinary amylis oil is particularly effective regardless of the origin.
[0012]
Although the usage mode of the product of the present invention is not particularly limited, it is used as a liquid agent, a spray type, a gel-like or solid deodorant, etc., and can be appropriately selected depending on a desired application.
[0013]
The content of Amiris oil which is an active ingredient of the product of the present invention can be exemplified by a range of 0.05% to 50% by weight, more preferably 0.1% to 10% by weight of the whole deodorant. A content of 0.05% or less is not preferable because the deodorizing effect falls to 50% or less in terms of deodorization rate. Addition of 50% or more enhances the deodorizing effect, but in an environment where a normal deodorant is used, it may not be preferable in terms of economy.
[0014]
The method for blending amylis oil is not particularly limited, but it is desirable to blend the deodorizer in a dilute organic solvent such as alcohol or a milky liquid. For example, if necessary, amylis oil can be emulsified with a surfactant together with other oily components, and blended into a liquid, a spray, or a gel. As the surfactant used in this case, for example, nonionic surfactants such as sorbitan fatty acid ester, POE sorbitan fatty acid ester, POE nonylphenol ether, POE allyl ether, POE lanolin derivative, POE castor oil derivative, POE alkylamine, and the like are used. be able to.
[0015]
In addition, amylis oil is ethanol, isopropyl alcohol, cetyl alcohol, hexadecyl alcohol, stearyl alcohol, phenylethyl alcohol and other alcohols, glycerin, propylene glycol, sorbitol, 1,3-butylene glycol, dipropylene glycol, isoprene glycol, etc. It can also be dissolved in a solvent such as polyhydric alcohols and impregnated with silica gel, powdered resin or the like to form a powdery or granular deodorant.
[0016]
In addition to the deodorizing active ingredient Amiris oil, known deodorants or fragrances, pigments, oils and fats, gelling agents, thickeners and the like can be added and used as desired. Examples of such known deodorants include oxidants such as hypochlorous acid, manganese dioxide, and benzoquinone, aldehydes such as glyoxal and acrolein, ketones, methacrylate esters, and α, β- Adsorbents such as unsaturated compounds, activated carbon, silica gel, and alumina can also be blended together.
[0017]
