0.1% Unknown solvent
There are no ingredients listed, only "99.9% pure dmso", but given DMSO's ability to cross the skin barrier, it's vitally important to either publish a MSDS, or at the very least print an ingredients list on the side for edification of what else might come along with the DMSO (into the body).<br /><br />Used extremely sparingly, and it worked as expected - although didn't get a blood panel after, so can't tell if it caused any secondary effects.
