Safety・Approvals and licenses


In order to use antibacterial agents correctly, it is necessary to pay attention to their handling after recognizing their harm to the human body and the environment. In developing antibacterial compounded products, antibacterial agents require excellent safety. Apacider AK / AW is an antibacterial agent with excellent safety based on the results of various safety tests.

Safety items

Evaluation results



Acute oral toxicity



Primary skin irritation

Mild irritation (PII: 0.13)

Mild irritation (PII: 0.04)

Skin sensitization







The value shown in the acute oral toxicity test is the mass that causes half of the sample to die when the sample substance is administered to male and female rats. Compared to the fact that sodium chloride is generally> 3,000mg / kg, it can be seen that Apacider AK and AW are very safe.


EPA (US Environmental Protection Agency)

This is an American institution that aims to protect and preserve human health and the environment related to air, water quality and soil. We carry out activities such as prevention of air pollution, water pollution, prevention of diffusion of harmful chemical substances that cause pollution of food and environmental pollution, and countermeasures.

Apasider AK and AW are antibacterial agents that have cleared EPA's strict safety tests. It can be used for a wide range of applications such as resin films, sheets, paints, processed paper products (excluding food wrapping paper and food contact), fibers, fabrics, non-woven fabrics, adhesives, and flexible tubes.
