First....Suspect that an octyl Siloxane would be classified by SCAQMD (for
non-Californians, this is Southern California Air Quality Management
District) as a VOC..

They do not understand that there is virtually any such thing as a
NON-Volatile organic.

However, they do understand about consumption and use, and if you can
demonstrate that your IPA in your ionic tester does not consume significant
levels of IPA, they will probably let you off the hook.

If you need help, I can assist you in "proving" this to the SCAQMD, I have
done this for some of our products.

I suspect that a lot of what you life about IPA for cleaning is that the
residues evaporate, leaving nothing significant behind, and if this is a key
property, you may be in trouble, as you will definitely need a volatile
organic to give you this property.

Good luck.
