Congo red indicator

Post by Marama T » 16 Jun 2020, 10:22

I was doing a bit of research on Congo red because I'm updating a few labels. Found this - "However, the use of Congo red has long been abandoned, primarily because of its carcinogenic properties. Wikipedia". And this - "Congo Red is an azo dye, it is toxic to many organisms and is a suspected carcinogen and mutagen. ... Its structural stability makes it highly resistant to biodegradation, and obviously its bright color and toxicity are entirely undesirable in the environment." AAAARGH! Will stash it for disposal I think.
