Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a cut flower prolongation agent composition in slurry form.

[0002]

2. Description of the Related Art Cut flowers start to lose their freshness immediately after flowering, and the petals and leaves become wilted and yellowed with the passage of time, eventually losing their appreciation value. In the cut flower business, where demand is expected to grow more and more in the future, preventing the deterioration of the freshness of this cut flower is the most important issue.

[0003] Conventionally, for such a purpose, as a cut flower life-prolonging agent, a liquid type in which a high-concentration liquid containing a cut flower life-prolonging agent component is used by diluting with water, and a predetermined amount of powder, granules or tablet life-prolonging agent There are two types of solid-type agents that are used by dissolving them in water, both of which are cut flower life-prolonging agents that are used by uniformly dissolving the life-prolonging agent component. However, these life-prolonging agent components are not efficient because the life-prolonging agent component is distributed over the entire container because not only the laborious concentration adjustment and stirring operation are required, but also because the life-prolonging agent component is distributed throughout the container. There is a risk of environmental pollution, and depending on the type of life-prolonging agent, treatment with a neutralizing agent is taken.

On the other hand, as a life-prolonging agent component of cut flower life-prolonging agents,
It has been suggested to use antibacterial zeolite, which is expected to have a water purifying effect due to antibacterial properties (JP-A-63-265809 or JP-B-4-28646). However, the above-mentioned antibacterial zeolite generally has an average particle size of about 0.6-2.
Since it is a fine powder of 0 μm, it has the drawback that fine powder is generated and scattered during handling, and that it adheres to surrounding equipment and the human body due to static electricity or the like.

Further, an apatite carrying an antibacterial metal,
Zeolite, phosphate double salt and other inorganic antibacterial agents are added in equivalent amounts of weak acid and alkali carbonates to form tablets, so-called effervescent tablets, which are of a tablet type in which inorganic antibacterial agents are dispersed throughout the container by carbon dioxide gas. A cut flower life-prolonging agent has been reported (JP-A-6-279202). However,
In this way, the method of dispersing the components with carbon dioxide gas is
The ingredients are not necessarily decomposed to the desired particle size, it is necessary to mix at least two components to generate carbon dioxide gas, and the economy is poor including the tableting process. , There is a risk of chemical damage to cut flowers and salt damage to drainage, and effervescent tablets are inherently extremely hygroscopic, and the reaction is easily promoted even with water in the air, and the reaction further progresses with water generated by the reaction. However, it is necessary to take measures such as hygroscopic packaging and addition of a dehydrating agent due to the drawback that it will collapse.

[0006]

Therefore, the present inventors have focused on the fact that the cut flowers absorb water only from the cut end, and are efficient and economical, have an excellent effect of prolonging the cut flowers, and are safe for the environment. As a result of intensive research to create a life-saving agent for cut flowers that does not require complicated work and special care, a sparingly soluble or insoluble component of life-saving agent for cut flowers was used and dispersed in water together with a dispersant. It was found that if a slurry is formed, a cut flower life prolonging agent composition that solves the above problems is obtained,
The present invention has been made.

EXAMPLES The cut flower prolongation agent composition of the present invention will be described in more detail below with reference to Examples, but it goes without saying that the present invention is not limited to these Examples.

Example 1 Preparation of Slurry To 1 liter of deionized water, 1 g of polyoxyethylene oleylamine (EO = 2) (ESOMIN O-12 (manufactured by Lion Corporation)) as a dispersant was added and the mixture was added at 10 ° C. at 20 ° C. Stir for minutes. After confirming that a uniform liquid has been obtained, while stirring, a silver zeolite (containing 5% by weight of silver), which is a cut flower prolonging agent, is added.
00 g was gradually added and dispersed. After mixing, the mixture was further slowly stirred at 20 ° C. for 1 hour to obtain a slurry.

Test Example 1: Slurry Dispersion Stability Test The slurry prepared in Example 1 was measured for dispersion stability after a certain period of time. The measuring method was to inject the slurry into a transparent lidded container (50 ml), and set the injection height immediately after to 100.
%. The height of the clear supernatant above the dispersion was measured and the sedimentation behavior was expressed as "% dispersion". Therefore, "100% dispersion" means that no supernatant layer was formed. As a result, 100% dispersion liquid was obtained even after 120 days elapsed, and the dispersion stability was good. Next, the long-term dispersion stability was tested by a freeze-thaw test performed to estimate the dispersion stability for a longer period (2 to 3 years). The slurry prepared in Example 1 was poured into the same container as above and -9
The mixture was allowed to stand at 14 ° C. for 14 hours and then at 23 ° C. for 10 hours, and the% dispersion liquid was measured. Also, in the same vessel, the consistency of the sediment formed after standing was examined by contacting with a spatula. In the sediment determination, the presence or absence of sediment formation and the degree thereof, and whether re-stirring of the sediment was easy, difficult, or impossible were also examined, and the sediment was evaluated according to the following scores.

A = no sediment in the dispersion. B = formation of a sediment with a soft consistency,
Easy to stir. C = precipitate formation with medium consistency,
Difficult to stir. D = Precipitation of hard consistency, no agitation possible. Further, the same test was continuously repeated for 3 days. The results are shown in Table 1.

Test Example 2: Test for prolonging life of cut flowers Length of roses (loterose) was reduced to 50 within 2 hours after flowering.
It was cut into cm and the lower leaves were removed to prepare 20 pieces in each section. About 60 liters of the slurry prepared in Example 1 was added to 2 liters of tap water.
20 mg of flowers were arranged and treated at 7 ° C. for 24 hours. After processing, switch to 2 liters of tap water, and then 22
It was observed at ℃, and the appreciation value, fresh weight, and bent neck rate were investigated. During observation, water was not changed, but only supplemented. Only 2 liters of tap water was treated as untreated, and the same operation was performed for comparison. The test results are shown in Table 2.

In the table, the average number of days of viewing is the average value of the number of days when the viewing value is lost due to criteria such as bent neck, wilting, dryness, dew core, and full bloom. The bent neck rate is the ratio of the number of flowers that have lost their appreciation value due to the bent neck. In addition, the cumulative weight index means the fresh weight of the flower at the start of the test is 100
In addition, it is a value obtained by accumulating daily weight gains and losses up to the average number of viewing days. The larger this value, the greater the weight gain during viewing and the more healthy the flowering progresses.
