The amt. of the particles of the polymer to be incorporated is preferably specified to 0.01 to 5wt.%. The perfumes may be any of natural perfumes, synthetic perfumes or the mixtures composed thereof, etc. The compounding ratio of the perfumes is preferably 0.1 to 10wt.% and the compounding ratio of the gelatinizing agent is preferably 0.1 to 20wt.%.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gel-like air freshener composition which is used in a lavatory, a changing room, a room such as a car, and a car.

[0002]

2. Description of the Related Art Heretofore, gel-like aromatic agents of this type have been
Dipropylene glycol alkyl ether and / or propylene glycol alkyl ether mixed with a gelling agent together with a fragrance for the purpose of releasing an aroma over a long period of time (JP-A-63-43666), magnesium powder, activated carbon, zeolite , And a solid inorganic carrier material selected from silica-based absorbents mixed with a gelling agent together with a fragrance (JP-A-59-5525).
No. 5) exists.

[0003]

However, the above-mentioned Japanese Unexamined Patent Application Publication No.
The gel-like fragrance composition disclosed in JP-A-3-43666 has a problem that the fragrance at the end of the aroma persistence period is inferior, and the gel-like fragrance composition disclosed in JP-A-59-55255 is However, there is a problem that the residue increases due to the inclusion of a large amount of non-volatile components.

Therefore, the present invention provides a gel fragrance composition which emits a fragrance over a long period of time and is particularly excellent in the fragrance at the end of the fragrance lasting period and has less residue after the end of the fragrance lasting period. It was made for the purpose of.

[0005]

Therefore, in the gel-like aromatic agent composition according to the present invention, polymer particles impregnated with a fragrance are mixed in a gelling agent. The polymer used in this invention includes polyethylene, polypropylene, polyvinyl acetate, polymethacrylic acid ester,
Ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer and the like, and the particle size of the polymer,
The average particle size is 1 to 50 in the range of 0.1 to 10000 μm.
00 μm (0.1 to 100 μm for porous polymer)
The average particle size is preferably 1 to 50 μm). If the average particle size of the polymer particles is 1 μm or less, the retention of the fragrance is weak and the fragrance does not last long enough to improve the fragrance at the end of the duration, and if it is 5000 μm or more (50 μm or more in the case of a porous polymer). The holding power of the fragrance is so strong that it is difficult to perfume regardless of the initial duration and the end of the duration, which is not preferable.

The amount of the polymer particles mixed is 0.
It is preferably set to 01 to 5% by weight. When the amount of the polymer particles mixed is 0.01% by weight or less, no scent eruption at the end of the fragrance lasting period and no improvement in the fragrance persistence appear,
When it is 5% by weight or more, the amount of residue after the end of the aroma duration is large, which is not preferable. As the fragrance used in this invention,
For example, it may be any of commonly used natural flavors such as floral, citrus, fruit, green, and cosmetics, synthetic flavors, or a mixture thereof, and is not particularly limited. Further, the blending amount of the fragrance is preferably 0.1 to 10% by weight.

The gelling agent used in the present invention is
For example, carrageenan, agar, locust bean gum,
Polyvinyl alcohol, gum arabic, gellan gum,
Examples include gelatin, amino acids, carboxymethyl cellulose and metal salts thereof, chitin / chitosan, sodium alginate, wax, sodium stearate, etc.
It is not particularly limited. Further, the amount of the gelling agent blended is preferably 0.1 to 20% by weight.

EXAMPLES The gel-type aromatic composition according to the present invention will be described in detail below with reference to examples. Examples 1 to 5 and Comparative Example According to the compounding amounts shown in Table 1, particles of a polymer (polyethylene, ethylene vinyl acetate copolymer) or particles of a porous polymer (polymethacrylic acid ester) and an activator were added to the lemon-based compounded fragrance. What was added and stirred was about 80 °
After being heated to C, the mixture was mixed with an aqueous solution of carrageenan or an agar solution that had been cooled to about 60 ° C, and this was mixed with about 50 ° C.
After the temperature was lowered to C, 150 g thereof was placed in a 200 cc beaker and allowed to cool at room temperature for about 1 hour to obtain a gel-like aromatic agent composition according to the present invention. Further, the same preparation as above was carried out except that polymer particles were added to obtain a conventional gel-like aromatic agent composition as a comparative example.

Next, sensory evaluation and measurement of scent concentration were conducted by 10 researchers on the persistence of aroma of these gel-like aromatic agents compositions. Sensory evaluation is 5 to 0
(5: very strong, 4: strong, 3: normal, 2: weak, 1: weak, 0: no odor), with a 6-point evaluation, immediately after the start of use, in the beginning of the duration, in the middle of the duration, and in the latter half of the duration. ,
At the end of the duration, each gelled fragrance composition was scored and averaged. The results are shown in Table 2. or,
The measurement of the scent concentration was carried out by using each gel-like aromatic agent composition 50
g into an ointment pot with a diameter of 70 mm, and a scent concentration measuring device (Alabaster UV EKW 8603; B
& H LABO.CO., LTD.). The results are shown in Fig. 1.
