I enjoy using Dr. Bonners soap.  I was thinking that I could add some EIS to it 
to give it a little more "zip."

The issue I have is that I have my SG6 generator set up to produce about a 10 
PPM concentration, and I would like to use less of a stronger concentration in 
the soap.  If I target 5 PPM, I would need to use a half and half mixture using 
the 10 PPM solution.  However, if I used a 50 PPM EIS, I would only have to use 
one part EIS for every 9 parts soap.  This would retain more of the attributes 
of the soap.

I think I have a couple of options.  One is to crank the SG6 all the way up and 
make sure I wipe down the electrodes part way through and hope for about 15 
PPM.  The other idea is to concentrate my 10 PPM solution to something stronger 
by boiling it on the stove.

Questions:

Is there a maximum concentration I should stay below?

Is there any known issues boiling an EIS solution?

Any other tips on fortifying soap?
