Abstract

PURPOSE:To absorb malodors and to release aromas so as to create a comfortable atmosphere by constituting the above compsn. of 5 to 70% A type synthetic zeolite and 95 to 30% X type synthetic zeolite adsorbed with an aromatic component. CONSTITUTION:The ratio of the A type synthetic zeolite is 5 to 70wt.%, more preferably 40 to 60wt.%. The trouble that a satd. state is attained by adsorbing the malodorous components to shorten the service life arises if the ratio is below 5wt.%. On the other hand, the trouble that the arom. characteristic weakens to shorten the service life arises when the ratio exceeds 70wt.%. The ratio of the X type synthetic zeolite is in a 95 to 30wt.% range, more preferably 60 to 40wt.%. The trouble that the arom. characteristic is weak and the service life is short arises as the ratio of the aromatic component is low if the above- mentioned ratio is below 30wt.%. The adsorption of the malodorous components weakens as the ratio of the A type zeolite is low if the ratio exceeds 90wt.% and the trouble that the aromatic component and the malodorous components are intimately mixed arises.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a granular aroma composition, and more specifically, it is made of a mixture of two types of synthetic zeolite, which absorbs bad odors and releases aromas. This invention relates to a granular aromatic composition that can create a pleasant atmosphere.

[Conventional technology]

BACKGROUND ART Air freshener compositions have been known that absorb bad odors emitted from cigarette ashes, butts, etc., and emit aromas such as perfumes, thereby converting the odors inside or indoors of automobiles into pleasant ones.

Such fragrance compositions include, for example, Japanese Patent Application Laid-open No. 63
-22174, in which a granular mass made of silica is impregnated with an odor absorbing material, and the granular mass is further impregnated with a fragrance, a solvent, a fixative, etc. However, the above-mentioned granular aroma compositions have problems in that they do not necessarily absorb bad odors sufficiently and do not sufficiently diffuse aromas.

[Problem to be solved by the invention]

An object of the present invention is to provide a granular fragrance composition capable of creating a pleasant atmosphere by absorbing bad odors and emitting fragrance.

[Means to solve the problem]

The present invention was made in view of the above-mentioned problems, and is based on A-type synthetic zeolite (CaO+A1*Os+2SiOz, n
X-type synthetic zeolite (CaO + A b (Is + 2-5S
tOx*nil 10) 95-30%.

In the following, the invention will be explained in more detail.

The granular aromatic composition of the present invention contains 5 to 70% of A-type synthetic zeolite as the first component, and X-type synthetic zeolite 95 to 95% containing aromatic components as the second component.
It contains 30%.

Synthetic zeolites are molecular sieves that have selectivity depending on their molecular size. The A-type synthetic zeolite used for adsorbing malodorous components in the present invention has a pore size of 3 to 5 pores and can absorb ammonia, hydrogen sulfide, carbon dioxide, water, etc. well.

The X-type synthetic zeolite has a pore size of 8 to 10 people, and the zeolite contains, for example, natural fragrances such as orange oil, orange flower oil, grapefruit oil, jasmine oil, spearmint oil, geranium oil,
Neroli oil, vanilla oil.

Hyacinth oil, bergamot oil, peppermint oil.

Peruvian balsam oil, benzoin oil, pepper oil.

Mimosa oil, lime oil, lavender oil, lemon oil.

There are rose oil, etc., and synthetic fragrances include eugenol,
galacturid, coumarin, geraniol.

Linalyl acetate, santalol, citral, citronellol, methyl dihydrojasmate, α-terpineol, vanillin, hydroxycitronellal, phenylacetaldehyde, β-phenylethyl alcohol, α-
Hexylcinnamaldehyde, heliotrobin, musk ketone, methylionone,! -menthol, linalool,
It adsorbs aromatic components that emit aromas, such as α-limonene, Lilial, rose oxide, etc., or a mixture of two or more thereof.

The above-mentioned X-type synthetic zeolite adsorbs aromatic components, but in the X-type synthetic zeolite, the components that have already been adsorbed are
It has the property of replacing components with a molecular diameter of 5 Å or less that are present in the atmosphere (air). Therefore, components having a molecular diameter of 5 Å or less that cause bad odors are adsorbed instead of aromatic components, and the aromatic components are released into the air.

In the present invention, the amount of A-type synthetic zeolite is 5 to 70
% by weight, preferably 40 to 60% by weight. If this amount is less than 5% by weight, there will be an inconvenience that malodorous components will be adsorbed and become saturated, resulting in a shortened usage period, while if it exceeds 70% by weight, the fragrance will be weakened and the usage period will be shortened. occurs.

On the other hand, the amount of type X synthetic zeolite ranges from 95 to 30% by weight, preferably from 60 to 40% by weight. If this amount is less than 30% by weight, the amount of aromatic components is small, resulting in a weak aroma and a shortened usage period. On the other hand, if it exceeds 95%, the amount of A-type zeolite is small, resulting in malodorous components. adsorption is weakened, and the aromatic components and malodorous components become mixed, resulting in inconvenience.

In the present invention, Y-type synthetic zeolite (
Na! O, AlgOs, 4.5SiOt, nH*0
) may be blended in an amount of 10 to 20% by weight.
The content is preferably 14 to 16% by weight, and more preferably 14 to 16% by weight.

By incorporating Y-type synthetic zeolite, there is an advantage that the aromatic component can be used for a long period of time.

Next, a method for adsorbing aromatic components onto the X-type synthetic zeolite of the present invention will be explained. For adsorption, permeation adsorption is preferred;
For example, this can be carried out by adding 10 to 20% by weight of a solution containing 5 to 20% of aromatic components to 100% by weight of the X-type synthetic zeolite and stirring. A solution of the aromatic component can be prepared using an organic solvent that best dissolves the aromatic component and has very little odor. Examples of such organic solvents include methanol, ethanol, etc. Examples include alcohols.Next, it can be obtained by air-drying the X-type synthetic zeolite adsorbed with aromatic components using dry air.

The granular aromatic composition of the present invention can be easily prepared by mixing predetermined amounts of the above type A synthetic zeolite and X type synthetic zeolite.

[Effect]

According to the present invention, it is possible to efficiently absorb bad odors and release aromatic components to create a pleasant atmosphere very easily.

〔Example〕

The granular aroma composition according to the present invention will be explained in more detail below.

1 lid 2 g of lemon oil was dissolved in 18 g of ethanol, and this solution was added to 100 g of X-type synthetic zeolite and stirred.Then, the mixture was air-dried to obtain X-type synthetic zeolite adsorbed with aromatic components. 50 g of this type-X synthetic zeolite and 50 g of type-A synthetic zeolite were mixed to obtain a granular aromatic composition according to the present invention.

When this granular aromatic composition was placed in a car cigarette ashtray and the presence or absence of malodor emission was investigated, no malodor was detected, and only the aroma caused by the aromatic components could be sensed.
