DEFINITION

Classification: 510/258

With corrosion or embrittlement inhibiting or solvent stabilizing component (e.g., pickling bath, etc.):

(under subclass 245) Compositions which include a component which inhibits corrosion or embrittlement of the surface being cleaned, or stabilizes a solvent.

(1) Note. The stabilized solvent is usually a halogenated hydrocarbon which is stabilized against metal-catalyzed decomposition.
