What is AbedulAg+ ?
When considering FDA certification, the following characteristics are believed to be necessary for antimicrobial agents:
1. No environmental burden.
2. Sustained antimicrobial effectiveness of 99.99%.
3. No issues with biocompatibility (cytotoxicity, sensitization, skin irritation).
4. The active species are not new substances (if it's a new substance, EPA verification is required).
5. Clinical verification is required.
"AbedulAg+" does not elute, thus posing no environmental burden, and retains 99.99% antibacterial effectiveness even after 300 washes when applied to textiles. This makes the need for reprocessing unnecessary, a critically important factor. In terms of biocompatibility, it has been confirmed to have no cytotoxicity. Particularly important is that the active species used, silver ions, are antimicrobial agents already approved by the EPA and FDA in precedent cases.
● Expected applications
"AbedulAg+ Technology" is expected to be used in a wide range of environmental hygiene applications such as medical care, clothing, transportation, food packaging, air & water filtration, and industrial and personal construction, to name a few.
● Features
-It is possible to make a paint-like solution and easily form a film on the surface of anything.
・ When processed into textiles, it has an antibacterial function of 99.99% (4Log) continuously.
-Since the antibacterial effect is continuous, resistant bacteria are unlikely to emerge.
-When processed into textiles, it can withstand more than 300 washes and does not require reprocessing.
・ Low-priced mass production of sewn textile products and roll fabrics is possible.
-Safe, without the problems of biocompatibility (cytotoxicity, skin irritation, sensitization).
-Ag ions are fixed to titanium dioxide at a high concentration, there is no re-eluting, and there is almost no
environmental load.
-There is no problem of environmental toxicity due to nanosilver.
-Unlike elution-type antibacterial agents, an antibacterial effect is generated on the contact surface even if it
does not dissolve in water.
-The antibacterial active species is Ag ion, which has been approved by the FDA for its safety and effect.
-There is no discoloration when textiles are processed. Any final dye coloring is possible.
● Safety of silver ion, which is an active
species
-
On June 10, 2009, the US Environmental Protection Agency (EPA) published rules on silver residue standards in foods. When a solution containing silver ions is used as a disinfectant on the food contact surface in food and beverage facilities, dairy products and food processing facilities, the final content of silver ions in the final product treated with the solution must not exceed 50 ppm. If so, it is decided to exempt the setting of the residual standard of silver in food.
-
The US Food and Drug Administration (FDA) allows up to 100 ppb of silver ions in drinking water.
● Material design of antibacterial agent "AbedulAg+" processed textiles
●Evaluation by an external institution of the number of washings and the antibacterial effect
In accordance with the washing standards of the Textile Technology Evaluation Council, repeated washes were carried out using the specified detergent. Even after 300 washes, it was found that the antibacterial effect of 99.99%, which is recognized by the FDA as having an antibacterial effect, was maintained for both Gram-positive and Gram-negative bacteria.
The number of times is judged as reprocessing of the antibacterial is unnecessary, so it is considered to be beneficial in terms of antibacterial effect management and economy.
