Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transparent and excellent appearance, and the addition of a perfume is accompanied by unfavorable changes such as deterioration of the perfume and abnormal odor. In addition to having an excellent fragrance deodorizing effect, it also shows excellent fragrance balance with the persistence and stability of the effect, it does not flow even if the container is inverted, and it is stored for a long time at high temperature It has excellent gel-like morphological stability that does not fluidize, and has a variety of properties such as maintaining its morphological stability even if it contains a large amount of perfume. The present invention relates to a manufacturing method that enables the manufacture of [0002] Hitherto, a gel-like aroma / deodorant composition has been used as a solid perfume, a room fragrance and the like. For example, dibenzylidene sorbitol which is a condensate of sorbitol and benzaldehyde is used as a gelling agent. A solid fragrance prepared by mixing dibenzylidene sorbitol and / or tribenzylidene sorbitol with a thermoplastic resin in a fragrance (Japanese Patent Publication No. 48-37825), dibenzylidene sorbitol, 3-methyl-3-
A gel-like aromatic deodorant composition containing methoxybutanol and / or ethylene glycol monoethyl ether and a fragrance (Japanese Patent Publication No. 63-64986) has been proposed. Further, a transparent gel-like fragrance which emphasizes aesthetics has been required, and it has been proposed to use aluminum octylate as a gelling agent. For example, a transparent gel fragrance made of aluminum octylate, limonene or odorless kerosene is proposed. Oily gel-like fragrance composition (Japanese Unexamined Patent Publication No. 1-32006)

Mixture with aluminum,
A transparent gel-like aroma / deodorant composition containing a benzylidene sorbitol derivative and an aroma and / or deodorant component has been proposed (JP-A-2001-46482). [0004] However, Japanese Patent Application Laid-Open No. 1-320 uses aluminum octylate (aluminum di-2-ethylhexanoate) alone as a gelling agent.
The production of the fragrance described in JP-A-063 has a disadvantage that heating at 60 ° C. or higher is required, and the fragrance described in JP-A-3-9758 using a terpene-based hydrocarbon is also used. The composition does not require heating during its production, but has the drawback that the fragrance is limited to citrus-based ones because it uses a large amount of terpene-based hydrocarbons. On the other hand, the fragrance composition described in JP-A-10-43282 using aluminum octylate and aluminum C12 to C24 higher fatty acids in combination as a gelling agent is disclosed in US Pat.
It can be manufactured without the need for heating at the time of its manufacture, it is transparent and excellent in appearance, it does not melt even at high temperatures, and it can give a wide range of scents, but when the container is turned upside down the gel flows out and loses shape Shape stability is not always sufficient, and further improvement is required. Further, Japanese Patent Application Laid-Open No. 2001-46482, which has been previously proposed by the present applicant, contains a mixture of aluminum octylate and aluminum C12 to C24 higher fatty acids, a benzylidene sorbitol derivative, and an aromatic and / or deodorant component. Is a transparent gel-like aroma / deodorant composition, which is transparent and excellent in aesthetic appearance, has excellent persistence and stability of the aroma deodorant effect, and has excellent gel-like morphological stability upon long-term storage at high temperatures. Although it has an effect, the workability at the time of production is poor because the time for the gel to solidify at room temperature is short, and further, the fragrance,
When used as a deodorant, there was a problem that residue was left dirty. The present inventors have conducted intensive studies and have found that octylic acid is added to a mixture of a benzylidene sorbitol derivative, an aromatic and / or deodorant component, and a C12-C24 higher fatty acid. Aluminum, -2
By mixing under a low temperature condition of 0 to 15 ° C., the gelation can be delayed, the workability at the time of production can be improved, the production can be easily carried out industrially, and the container can be turned upside down. It does not flow out and has morphological stability that does not cause fluidization or shape loss even when exposed to high temperatures for a long period of time.Furthermore, the shape of the gel composition after use is reduced overall but impairs aesthetics. It has been found that a transparent gel-like aroma / deodorant composition can be obtained, and the present invention has been completed. Thus, according to the present invention, a benzylidene sorbitol derivative, an aroma and / or deodorant component and C
