Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cut flower activator capable of keeping cut flowers observable for a long period of time.

[0002]

2. Description of the Related Art Conventional methods for keeping the freshness of cut flowers at home and at flower shops include a draining method, a boiling method, a burning method, and a root tapping method, all of which are activated by improving landing. However, the effect is not sufficient. In addition, even if such a treatment is performed, cut flowers with high bacterial sensitivity, especially roses, etc.When the number of bacteria in the irrigation water increases, it causes conduit blockage, it will not lift water and it will vent neck, so irreparably irrigation water Further work such as exchanging and switching back is required. Therefore, a cut flower activator or a cut flower life prolonging agent containing various fungicides has been proposed. As the bactericide, silver compounds and various synthetic bactericides have been used, but both are highly toxic to the human body and may have a toxic effect in the event of accidental ingestion by an infant at home. There is a problem that it also causes skin roughening and skin irritation when it comes into contact with the skin.

[0003]

DISCLOSURE OF THE INVENTION The present invention aims at keeping live water in a clean state where bacterial growth does not occur for a long period of time.
A safe cut flower that can be held in a state where it can be viewed for a long period of time, and that it does not show toxicity even if swallowed by humans, does not cause harm even if it comes into contact with skin, or is extremely hypoallergenic. The purpose is to provide an activator.

[0004]

In the present invention, cetylpyridinium chloride is a bactericide having extremely low toxicity to the human body. When it is used in combination with an inorganic acid salt of aluminum,
It has been completed by finding that a high bactericidal effect can be obtained at a concentration extremely lower than the concentration used alone and a synergistic effect can be obtained. That is, the cut flower activator of the present invention is characterized by containing cetylpyridinium chloride and a water-soluble inorganic acid salt of aluminum.

[0005]
