One thing I'd add is that as long as a component poses a health or physical (such as combustibility) hazard, it must be listed. There's no exception for proprietary compounds -- they must also be listed as ingredients -- but they may be listed under an anonymous name such as "proprietary lube oil," rather than something more specific like "heavy naphtha distillate, CAS #XXX-XXXXX." Other aspects of that proprietary compound must be revealed as well, such as chemical qualities, fire control, first aid, etc. For that matter, should a medical provider or a health & safety administrator request the identity of a proprietary compound, it MUST be revealed to that party, per federal law.
