These are additives in ceramic glaze of toilets that the companies claim have some antibacterial action. In the case of CeFIONtect, they also claim that the glaze is smoother, making it physically more difficult for bacteria to make a home in microscopic crevices.
Based on similar products, I would guess that these technologies include a nano silver or titanium dioxide additive.
Toto the company that makes CeFIONtect antimicrobial toilet coatings holds a patent for a titanium dioxide additive to ceramic. Titanium dioxide and UV light create a photocatalytic reaction, like those found in PCO and PECO air purifiers. This can kill bacteria.
Titanium dioxide and nano silver ions can also be found added to ceramic tiles as well.
Both of these technologies could be advertised as natural, non-toxic, antibacterial, and ionic.
However there could be more going on than this, as one commenter noticed a smell (and porcelain toilets don’t normally have a smell).

I find that my American Standard toilet with everclean coating has a chemical smell! Anyone know why?
Thanks!

Even after wiping it down fully?

Would the Cefiontect coating pose a problem for someone with mcs who is very sensitive? I noticed there is a prop 65 warning on the Toto drake toilet because of lead I think due to the coating. Do you have any recommendations?

No problem with titanium dioxide coatings, it’s no different than the paint on the walls which also has a lot of titanium dioxide. nano silver should be fine as well, it’s like colloidal silver. Lead won’t have any route to enter the body.
