Many pathogenic microorganisms are hidden in the sand. Some bacteria can be serious if they enter the mouth of a small child who is not resistant to the body or if they enter the body through a wound on the fingertip. Protect your children from infection by reducing bad bacteria in the sand. Annual management system Our feature is that the disinfection work is not "only mixing antibacterial agents" or "spraying sandbox / ozone water only once", but sandbox disinfection is performed in two stages of immediate effect and sustainability. The effect of what is not visible is evaluated and judged by conducting a bacterial test. Another feature is that we provide after-sales service throughout the year. March-June Bacterial test Primary disinfection Secondary disinfection June-September Secondary disinfection Bacterial test September-November Secondary disinfection Bacterial test Flow of sandbox disinfection [1] Sandbox before work Remove any foreign matter or debris. [2] Bacterial test sampling before disinfection Sand is collected from several sandboxes and the pollution status is analyzed. [3] Primary disinfection Spray the disinfectant using a power sprayer or the like. * Upon request, we also disinfect playsets and gardens. [4] Secondary disinfection (mixed with disinfectant eco-beads) After the primary disinfection, eco-beads are mixed into the sand surface. Since it is soluble, it has a long-term disinfecting effect. [5] Bacterial test sampling after disinfection Take a sample to check for bacteria after disinfection. [6] Leveling What are eco beads? Ecobeads is a registered trademark of Sogo Medical Service Co., Ltd., and is a soluble disinfectant containing potassium monosulfate peroxide as the main component. Simply put, it is a disinfectant that produces hypochlorous acid water. It is made with due consideration for safety. As a result of orally administering 500,1000,1500,2000 mg / Kg of eco-beads to mice and examining the toxicity, no toxicity was observed. [Result table] Lethal cases, case fatality rate and LD50 value Test group Dose Case fatality rate over time Lethal dose LD50 value (n = 10) (J / L) 2 hours 1 day Day 2 3 days (%) (J / L) 1 0 0/10 0/10 0/10 0/10 0 1 500 0/10 0/10 0/10 0/10 0 1 1,000 0/10 0/10 0/10 0/10 0 1 1,500 0/10 0/10 0/10 0/10 0 1 2,000 0/10 0/10 0/10 0/10 0 > 2000 LD50 value: With a case fatality rate concentration of 50% or more, the maximum dose is specified as 2000 mg / Kg in the acute toxicity test according to the OECD guidelines. "Changes in bacterial count over time due to sandbox disinfection using eco-beads" Number of coliforms (It is used as an index of pollution status: bad bacteria) Viable cell count (Bacteria that mainly produce nutrients for plants with all bacterial numbers: good bacteria) After the primary disinfection, the viable cell count temporarily decreases and returns to the original state, but the coliform bacteria remain at a level of 1000 cells / g or less, which is almost uncontaminated. Primary skin irritation test As a result of observing the stimulating response to guinea pigs, eco-beads were evaluated as having no skin irritation. Eye corneal / conjunctival irritation test As a result of irritating the cornea and conjunctiva by dropping an aqueous suspension of eco-beads onto the corneal surface of a guinea pig, no hypersensitivity reaction was observed. The annual management fee is 200,000 yen or less in a sandbox of about 20 m2 . We will quote according to the conditions.
