Sherry:

MSDSs are only required to list "hazardous ingerdients" present in
concentrations greater than 1% (0.1% for carcinogens), with some
additional qualifications. The OSHA definition of "hazardous
ingredient" is in 29 CFR 1910.1200 Appendix A.

The water soluble wash probably contains a non-hazardous surfactant.
Even a low concentration of surfactant could permit the formation of a
turpene-water emulsion when the cleaning solvent and water are mixed.
If you call the manufacturer, they may volutarily tell you what the
surfactant is.

P.S. Is there a vendor of these screen cleaners in our Region?
