Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to solid fragrances, particularly solid fragrances containing polynorbornene.

Conventional technology A variety of solid fragrances have been researched and developed to infuse the inside of seedlings and other confined spaces, but all of them have problems such as aroma, shape retention, manufacturing workability, stability, etc. There was still room for improvement in this respect.

In addition, in recent years, as living standards have improved, water storage type flush toilets have become popular, and various research and development efforts have been conducted on air fresheners for these toilets and in-tank toilet cleaners. The development of products that combine both cleaning and detergent properties is also progressing. However, the above-mentioned air fresheners are essentially those that can scent a space when they come into contact with the air, whereas the method cleaners are those that dissolve in water when they come into contact with water and have the effect of cleaning toilet bowls and other areas. , both have essentially different usage forms and functions, and can be used separately depending on the
It is possible to simultaneously and fully exert both functions, namely, the function of gradually dissolving to produce the desired cleaning effect and the function of volatilizing into the air to create an aromatic atmosphere, simply by combining these functions. Have difficulty.

Problems to be Solved by the Invention An object of the present invention is to improve conventional fragrances and to provide a new fragrance or fragrance cleaning agent that functions as both a fragrance and a cleaning agent.

Means for Solving the Problems According to the present invention, a solid fragrance characterized by containing polynorbornene is provided.

As a result of extensive research, the present inventors have discovered that the above-mentioned polynorbornene has the ability to absorb and solidify a large amount of fragrance ingredients at room temperature, and that this oil-absorbing ability does not decrease even in the presence of water. They discovered that objects are stable against heat and do not lose their shape even at temperatures around 70°C, and based on this knowledge they have completed the present invention.

Therefore, the fragrance of the present invention can contain a large amount of fragrance ingredients based on the use of the above-mentioned polynorbornene,
Furthermore, there is no need for heating or warming when testing into a product form, making the manufacturing process easy and simple, and there is no accompanying deterioration of fragrance components, resulting in extremely excellent aromatic properties. . In addition, the above-mentioned polynorbornene does not reduce its oil-absorbing ability even in the presence of water and can selectively absorb and solidify fragrances, so the fragrance of the present invention can also be made into a drogel type. Also provided are hydrogel-type fragrances as described above containing perfume in concentrations.

Further, the fragrance of the present invention is stable against heat due to the use of the above polynorbornene, and has excellent shape retention that does not lose its shape even at around 70'C.

Furthermore, based on the various advantages mentioned above, the aromatic agent of the present invention can be used as an aromatic cleaning agent that maintains the above advantages by adding surfactants, chlorine-based cleaning agents such as hypochlorite, etc. can. That is, if the aromatic cleaning agent is installed, for example, in the hand washing section of a water storage tank, the cleaning agent components will be eluted into the water during flushing, and the cleaning effect will be achieved. The product itself does not come into contact with water and is exposed to air, which can effectively achieve the purpose of spatial perfuming. What is really surprising is that even after repeated flushing, the product itself does not disintegrate and flow out, and the volatility of the fragrance is not inhibited.This, combined with the product's high fragrance content, allows it to maintain a sufficient fragrance as an air freshener. can. In particular, the fragrance of the present invention is stable even at a high fragrance content and can more effectively perfume a space.

The fragrance of the present invention essentially contains polynorbornene. The polynorbornene is a polymer obtained by ring-opening polymerization of norbornene obtained by a Diels-Alder reaction between ethylene and cyclopentadiene, and has a structure in which double bonds and five-membered rings are alternately bonded, Typical examples are Teha, France CdF Cemi (CdF
"Nor Solex" developed by Chime
