From Iris Nevins:

Well, I found one place to find out more about carrageenan. The biopolymer
division of FMC prepares carrageenan for a variety of uses in food,
pharmaceuticals, and other applications. They are the folks who make the
Viscarin GP-209 that Iris Nevins recommends (it is in their pharmaceuticals
list). In case you are actually interested in the technical side of
things, this is great fun to look at.
