Those side effects don’t seem so bad. I’m not planning to put it in my ear; I don’t get any irritation or allergic reactions, and the way I’m using it (applying a toothpaste containing it around my implants after brushing my teeth, as prescribed by my dental hygienist) doesn’t seem to discolor my teeth either. 4-chloroaniline and hexamethylenediamine do look scary though...
