We are conducting joint research with Dr. Hirokazu Masai (Engineering) and Dr. Hideaki Maseda (Agriculture) on the
structure (mechanism analysis) of titanium phosphate-based compounds, the main ingredient of Ecokimera, and elucidationof their action based on microbiological (genetic) findings on the cause of material activity, and are working consistently tocontribute to virus control in Japan and overseas. From September 2022, we also started Chronic Toxicity Evaluation Using
Individual Fish with the cooperation of Dr. Takashi Kawasaki (Science) of the same institute to verify the presence orabsence of chronic toxicity to aquatic organisms and its effects on microorganisms.

Activation mechanism

Under the theme of Functional Verification and Application Development of the Ecokimera S Series, we are conducting
joint research and development with Professor Hiroshi Yoneyama (M.D., Ph.D.) in the field of animal microbiology toevaluate the antimicrobial activity against bacteria causing infectious diseases in animals (livestock) and the applicability of deodorizing, antibacterial, and antiviral functions to the field of animal husbandry, etc. * The research results
about our product were presented at the 66th Annual Meeting of the Japanese Society for Staphylococcal Research.
(October 29, 2022)

By applying Ecokimera with a dedicated spray gun (spraying equipment and coating method using thisequipment, Patent No. 6932410), nanoparticles derived from titanium phosphate-based compounds aredeposited on the substrate surface.
It is believed to decompose odor components or physically destroy bacteria and viruses mainly by radical
reactions on the surface of nanoparticles deposited during application. It is thought that the large number ofnanoparticles on the applied surface increases the surface area, resulting in high activity.

S Series: Supportive Data for Adhesion
Spray application of Ecokimera to various materials deposits nano-sized particles on the surface. These particles adhere
firmly to the surface of the material, so the stable effect lasts for years without the use of binders.
As empirical data on the adhesion between the surface and Ecokimera, the presence of titanium components derived fromtitanium phosphate-based compounds on a glass surface sample has been confirmed even after a cloth friction test of
10,000 rubs in an experiment conducted at the Kyushu Synchrotron Light Research Center in Saga Prefecture (results ofjoint research with the National Institute of Advanced Industrial Science and Technology). Third-party testing has also
shown that the antibacterial activity of fiber material samples after 50 washings is comparable to that of untreated samples.

As the importance of anti-virus measures rises, there are two types of viruses that must be considered:enveloped viruses, which have protein shells for which alcohol disinfection is considered effective, andnon-enveloped viruses, which have no shells. The evidence suggests that the S Series is effective against
both types of viruses.
