If you read the filings from the company, you will note that the company stopped selling it's own product directly to the retail market way back in October 2007. They didn't see a need to have a public website since their plan was to only sell the bulk AC-11 product to companies they had licensing agreements with who would then use the bulk product to make any number of other products which they themselves would then market and sell.
So the answer to your question is ... they don't have a public website anymore. That may change at some point in the future, but for now you won't find one.
