DEFINITION

Classification: 516/152

The agent contains mineral-oil* sulfonic acid (e.g., cyclohexylamine salt of mahogany* or green* acid):

(under subclass 151) Subject matter in which the salt contains mineral-oil* sulfonic acid, such as, cyclohexylamine salt of mahogany* or green* acids.

(1) Note. Mineral-oil* sulfonic acid results from mineral-oil* (see glossary definition) which has been sulfonated, e.g., by sulfuric acid. Mahogany* acid is the oil-soluble fraction of sulfonation of petroleum* oil; green* acid is the oil-insoluble fraction of sulfonation of petroleum* oil.

(2) Note. A substantially pure hydrocarbon is not a mineral-oil*, hence the sulfonation product of such does not constitute an agent* for breaking (resolving) or inhibiting for this subclass.
