This caught my eye.
More than just water and IPA, has an added surfactant.

This is in milliliters, so here are the conversions to ounces.

670 ml. Or 22.65 ozs. of DI water
300 ml. Or. 10.14 ozs. of 99% IPA
20 - 25 ml. Or .67 - .84 ozs. of SLES . (sodium lauryl ether sulphate)
1/2 ml. Or .0169 ozs. of liquid Dye

I did find the SLES & liquid soap making Dye at AMZ.

The only thing is the 99% IPA.
I can find 70% IPA, which adds more water to the mix.??
(Most likely be rounding these amounts off any way)
