ENDURING SHINE THROUGH
THE POWER OF WATER
NEW CERAMIC TECHNOLOGY
IDEAL FOR STAIN-RESISTANT*1SANITARY WARE
Waste stain in the toilet bowl washes away easily with just one flush.
AQUA CERAMIC prevents the formation of lime scale that leads to brown-ring stains,*2
allowing brand new shine to continue for 100 years with basic, regular care.*1
UTILIZING THE OIL-REPELLING
PROPERTIES OF WATER
The major cause of stubborn toilet bowl stains is the oil contained in human waste. AQUA CERAMICfs innovative technology allows the water to penetrate beneath any waste that may have attached to the ceramic and lift it using the oil-repelling properties of water.
EFFECT THAT LASTS FOR
OVER 100 YEARS
Assuming that a toilet bowl is scrubbed back-and-forth twice with a toilet brush every day, in 100 years, it will have been scrubbed approximately 70,000 times. Tests confirm that AQUA CERAMICfs waste resistant functionality will be the same as when it is brand new, even after a 100 yearsf worth of scrubbing.

COMPLIANCE WITH INTERNATIONAL STANDARDS
After thoroughly rinsing off any waste, the antimicrobial power of silver ions prevents bacterial growth, reducing stain, lime scale, and odor.
What are antibacterial toilets?
Antibacterial is a term describing a state where growth of bacteria on the surfaces of products is suppressed for a long period of time. Toilets that are equipped with a mechanism that inhibits bacterial growth are referred to as antibacterial or gkohkinh (Japanese for antibacterial) toilets. Unlike the process of eradicating pre-existing bacteria, antibacterial agents control the growth of bacteria, ensuring toilets to be safe of germs. SATIS is a certified antibacterial product, in compliance with SIAA KOHKIN international standards.
What is a SIAA KOHKIN mark?
The SIAA KOHKIN mark is a logo created by the SIAA (Society of International sustaining growth for Antimicrobial Articles) to be attached to antibacterial or gkohkinh products. The SIAA seeks to promote appropriate and reliable antibacterial products and allows its SIAA KOHKIN mark to be attached only to products that meet SIAAfs three criteria: antimicrobial properties, safety, and appropriate labeling. With respect to antimicrobial properties, rigorous standards defined by SIAA need to be met, such as the requirement for the amount of bacteria on the surface of the product treated with antibacterial agent to be 1/100 or less of that of a non-treated product, and for the antibacterial effect to be retained after durability tests. Products are also required to pass safety tests to ensure that the antibacterial agent is not toxic when swallowed, that no inflammation occurs upon having physical contact with the agent for a long period of time, that there is no effect on genes (DNA), that the agent causes no allergic reactions, etc. SATIS, certified as a SIAA KOHKIN product, is therefore a safe antibacterial toilet with high antimicrobial properties.

Takemura: I believe that an gidealh toilet is one that is easy to clean and stays shiny forever. It was evident from our questionnaires that our customers also thought so. Powerful flushing system has been the key selling point of LIXILfs toilets. Toilets have become more environmentally friendly, and only 4 liters of water is required per flush today, a significant reduction from the previous 13 liters. Indeed, customers have asked whether it is really possible to completely flush all the waste with only a small amount of water.
Okumura: To facilitate reduction in water usage, our toilet bowl design developers have been studying technologies to enhance how toilet bowls are rinsed, to ensure thorough rinse even with minimal amount of water. In the meantime, in the R&D Division, we have been engaging in an extensive fundamental research to revisit the materials used for toilet bowls, to figure out a way to prevent waste from attaching to the ceramic in the first place.
Tackling Various Challenges
Okumura: Oil contained in human waste is the primary reason for waste to stick to toilet bowls. Although it depends on the personfs diet and/or health conditions, approximately 5% of human waste is oil. The revolutionary AQUA CERAMIC technology allows water to penetrate between the waste and the ceramic surface of the toilet bowl and lift off the waste, utilizing the oil-repelling properties of water.
Takemura: I was really surprised when I first saw the effects of AQUA CERAMIC. I was excited and impressed to see waste just simply lift off and flow through. But at that time, the cost was high and the ceramic texture was not as good as the current product. I made some challenging requests to Okumura-san, to improve the texture of the ceramic to the same level as other LIXIL products and figure out a way to bring the cost down, so that the technology can be enjoyed by a broader customer base.
Okumura: In our R&D lab, we have a series of researches going on to tackle various challenges. It takes at least 2-3 years to obtain any result, and we have some researches that, while intermittently, have gone on for over 10 years. Many of our researches do not make it to commercialization. Before AQUA CERAMIC, I engaged in four research themes, all of which did not result in an end-product, so AQUA CERAMIC is the first research for me to see to fruition. So, as the possibility of commercialization became more and more real, Takemura-sanfs challenging requests made me even more motivated.

Okumura: I introduced AQUA CERAMIC to members of LIXILfs overseas offices and they were equally impressed with its performance. As a technician, Ifm delighted that AQUA CERAMIC is a technology that is universally accepted and welcomed around the world.
Takemura: While Okumura-sanfs role is research, he was proactively involved in the development and production discussions and made a huge effort to commercialize AQUA CERAMIC. Ifm looking forward to the launch of AQUA CERAMIC and hope our customers feel the same excitement and joy I felt when I first experienced the product.
