Well, actually, it's correctly linked, I just mis-stated it in the prior statement (incorrectly as "perchlorate" rather than "percarbonate").

You're right, I was having a blind moment there.

The percarbonate is slightly hazardous, but not nearly as much. According to the MSDS it can cause respiratory irritation when inhaled. It can also cause skin blistering at high exposure, but as you said, hot butter will burn you, too.
