I can not be sure if it is is my denatured ethanol, since i do not have a  
MSDS for the brand i currently use. But all MSDS i've downloaded listed  
MEK, and i used several brands over the years, so it is highly likely some  
if not all contained MEK.

I have used it on ABS countless times, and never observed any trouble like  
surface damage in any way.
Maybe the low percentage renders MEK harmless.
