If I swallow this is it harmful?!
Question: If I swallow this is it harmful?
Answers:
Well usually anything a doctor (or as a science experiment in your situation) puts in your mouth for any reason, is not harmful to the body (except his hand perhaps! :P) But as far as i know, Alginate is also used as a weight-loss pill, so no, I highly doubt it is going to poison you. Although it could give you a stomach ache for a short while.
Just don't drink formaldehyde if you're dissecting anything in the future! ;)
Nope alginate is biologically neutral. Perfectly safe.
alginate is from brown algae. its fine.
