(under the class definition) Products and compositions which include only mineral oils or mixtures of two or more mineral oils or mineral oil fractions, and processes of preparation of such mixtures which include only a mixing or blending of the mineral oils with each other.
(1) Note. Mixtures of mineral oils with a nonmineral oil material are not included in this or indented subclasses but
are classified elsewhere, usually on the basis of the use, property or function of the composition. See (1) Note in the class definition of this class (208).
(2) Note. Processes of preparation of mineral oil compositions which involve a chemical conversion of the hydrocarbon, a refining treatment or fractionation step, whether or not combined with a mixing or blending step, are classified in the subclass providing for the particular treatments involved.
