DEFINITION

Classification: 508/398

With nonhydrocarbon organic compound in addition to those remaining from overbasing process (e.g., antioxidants, VI improvers, etc.):

(under subclass 391) Compositions which contain, in addition to the overbased or carbonated sulfonate and any material remaining from the overbasing process, an organic compound that is not a hydrocarbon.

(1) Note. This subclass is designed to encompass compositions which include (1) overbased or carbonated sulfonates, (2) any materials remaining from the overbasing process and (3) additional additives, which are nonhydrocarbon organic compounds.

(2) Note. See Notes to the Class Definition for the definition of an organic compound.
