It's something a bit difficult, since mica and titanium dioxide are the 'base' for mineral foundation . But then, there's everything in the world - i can't help you now, but if you do a research you might come with something! And also, there's brands with less mica than others - have you ever tried them?
Very heavy coverage. Samples are .35 each. I tried it and I could not get the application/colour right.
This is a link from Mineral Makeup Mania that lists major brands and the ingredients. Besides Cory, take a look though and you should see some other companies.
