Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a granular aromatic deodorizer, and more particularly to a granular aromatic deodorizer useful for removing malodors from various malodor sources.

(Conventional technology and its problems) Conventionally, deodorizing agents have been used against various sources of bad odors.

On the other hand, air fresheners are used to mask bad odors so that they are less noticeable.

In the case of the above-mentioned deodorizer, if even a small amount of bad odor remains, the bad odor will not be felt, and although it physically removes most of the sources of bad odor, it has little effect on removing bad odor sensually. The odor removal effect is not sustainable, and the odor removal effect will eventually be lost.

Furthermore, in the case of the above-mentioned fragrances, the bad odor does not decrease, so there is a drawback that depending on the use and location, the fragrance may make the user feel even more unpleasant. Therefore, the object of the present invention is to use a fragrance that has both a deodorizing effect and a masking effect. However, it is an object of the present invention to provide an aromatic deodorizing agent that maintains the deodorizing effect by a masking effect even if the deodorizing effect is lost.

(Means for solving problems) The above objects are achieved by the present invention as described below.

That is, the present invention is a patented aromatic deodorizer characterized by forming a fragrance, a zinc compound, and an organic acid into granules.

(Function) By forming the fragrance and deodorizer into granules, the masking effect can be exerted by the fragrance without losing the deodorizing effect of the deodorizer.

(Preferred Embodiments) Next, the present invention will be described in more detail by citing preferred embodiments.

The fragrance used in the present invention is a fragrance that does not chemically react with the deodorizing component described below, and for example, fragrances commonly used under names such as citrus, floral, rose, lavender, sandal, etc. can be used. It is also preferable to use these fragrances that have been microencapsulated with other substances because the fragrance duration can be maintained for a long period of time.

The amount of the fragrance to be used is arbitrary, but preferably about 0.5 to 50 parts by weight per 100 parts by weight of the deodorizing component described below.

The individual deodorizing components used in the present invention are all known compounds, and the zinc compounds include various zinc compounds, such as zinc oxide, zinc sulfate, zinc chloride, zinc phosphate, zinc nitrate, and zinc carbonate. Inorganic zinc compounds such as zinc acetate, zinc oxalate, zinc citrate, zinc fumarate, zinc formate and other organic zinc salts can be used, and particularly preferred are zinc white (zinc oxide) and zinc carbonate.

The organic acids used in the present invention include aliphatic acids, aromatic acids, and polymeric acids.

Preferred aliphatic acids are aliphatic polycarboxylic acids, such as oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, fumaric acid, maleic acid,

Particularly preferred are polymers with carboxylic acid groups.

The deodorizing component consisting of a zinc compound and an organic acid as described above is
Their usage ratio is also important, and if the total amount is 100 parts by weight, the ratio of the zinc compound is 10 to 90 parts by weight and the organic acid is 90 to 10 parts by weight. In this ratio, the objectives of the invention are best achieved. If the usage ratio is outside the above range, the deodorizing effect will be insufficient, which is not preferable.

The granular aromatic deodorizing agent of the present invention can be obtained by mixing the above-mentioned components, optionally adding a suitable resin liquid as a binder, and forming the mixture into granules.

The binder used is suitably a low melting point organic compound, wax, or an aqueous or organic solvent solution of a synthetic resin or natural resin. Low melting point organic compounds and waxes are particularly preferred since they do not require subsequent drying. Such binders include medium to higher fatty acids such as stearic acid, lauric acid, linoleic acid, naphthenic acid, 2-ethylhexoic acid, and octylic acid, and zinc, calcium, magnesium, aluminum, lead, and tin of these fatty acids. , metal salts such as lithium, polyethylene wax, polypropylene wax, microcrystalline wax, polyethylene glycol, hydroxystearate ethylene bisamide (K-3 wax), montan acid wax, ethylene-vinyl acetate copolymer wax, and the like. Of course, low melting point organic compounds other than these can also be used. Other polymer binders such as polyvinyl alcohol, polyacrylic acid, and carboxymethyl cellulose can also be used.

It is preferable to use the binder as described above in a proportion of about 5 to 100 parts by weight per 100 parts by weight of the deodorizing component. If the amount used is less than the above range, it will be difficult to obtain a granular deodorizing agent. If the amount used exceeds the above range,
The deodorizing effect of the deodorizing component is hindered.

The granular aromatic deodorizer of the present invention is produced by uniformly mixing the deodorizing component and aromatic agent described above with a binder, plasticizing the mixture by heating or adding a small amount of liquid, and granulating it into granules of an appropriate size. obtained by A preferred granulator is a press having a screen mesh with appropriately sized holes. The resulting granular aromatic deodorizer may have any diameter, but a diameter of 0.5 to 5 mm is preferred for boat fishing.

The granular aromatic deodorizing agent of the present invention has the above-mentioned components as essential components, and various other conventionally known additives for resins, such as
Colorants, fillers, extender pigments, plasticizers, stabilizers, ultraviolet absorbers, etc. may be optionally blended as necessary.

The granular aromatic deodorizer of the present invention can also be obtained by simply mixing the above components and extrusion granulation, etc. The particle size of the granular aromatic deodorizer obtained is about 0. Approximately 1 to 5 mm is suitable, but it may be finer (but coarser) depending on the purpose.
