Wayne and others:
Trichloroethane (TCA) is also a bad actor though believed to be less toxic than TCE. It is different from trichloroethylene (aka trichloroethene or TCE) by the presence. TCE has a double bond between the carbon atoms whereas the TCA has a single bond.
In general, chlorinated organics are worse than non-chlorinated organics from toxicity/biodegradability standpoints.
With respect to LPS' claim, I suppose that stating that it is TCA free carries an implication that it is free of TCE although they are different chemical compounds. An MSDS sheet for the stuff would disclose that presence of toxic constituents and could be requested from the manufacturer.
