We offer the design and construction of log cabins. All of our employees love wood. I love wood and want people to learn of the good points of wood, so the deodorizing and antibacterial activities of cypress caught my eye. That is why I began the development of deodorant sprays.
At first, I was providing analyses of odors to the analysis center. I achieved some outcomes, but I was not able to solve the central question about what was going on.
I have a background in liberal arts and bought reagents for experiments for the first time. However, I was reassured because everyone, such as Mr. Sakaguchi, helped me advance my experiments.
―(Sakaguchi) Since he had some data from the analysis center, I got the feeling there would be chemical interaction in deodorizing. I am not an odor expert, which is why I’ve come to handle experimental values obtained from studies to discover the Raman spectroscopy.
Actually, cypress is very popular in China and South Korea. Since the early stage, I started taking into consideration overseas sales. In addition, I hope that I will futher advance research together with Nagoya University and continue further studies in the mechanism for deodorizing and the interaction with other odorous components through the Nanotechnology Platform.
Rattan is a plant that grows in Indonesia. It has also been imported into Japan since long ago and processed into rattan products. Rattan was being laid on the floor of kimono fabric shops. The advantage of rattan is its deodorizing effect. I didn’t notice it until several decades ago, when I went to a hot spring to change the old rattan mat in the changing room. I found that it appeared worn and tattered but didn’t smell at all. I thought this was amazing and started working on the application of this finding deodorant products.
We were working on the design of our new self-developed products in coordination with JST. The relationship made me aware of the Nanotechnology Platform. I thought that it was necessary to thoroughly investigate the deodorizing effect of rattan so that people would learn about the good points of rattan.
I was impressed at seeing the structure of rattan for the first time. Regarding tobacco smoke absorption, I could clearly observe the particles of tobacco smoke. It means I had credible evidence other than a sensory test, so I was very satisfied.
―(Hayashi) Since it was the first time to observe natural materials like rattan using scanning electron microscopes (SEMs), the work was very interesting from the perspective of the technical staff. The structure was unique. In the tobacco tests, we did all kinds of things for absorption. Being able to observe even the particles was a good experience for us.
We showcased the products at exhibitions in the United States, where we gave explanation by using the SEM images. Everyone seemed interested.
To let more people to know about the good points of rattan—we hope to conduct scientific investigations by continuing the use of the Nanotechnology Platform and seeking support from Nagoya University.
