DEFINITION

Classification: 162/179

(under subclass 158) Processes and products which include a fat, fatty oil, or higher fatty acid.

(1) Note. A higher fatty acid is a monocarboxylic acid containing an unbroken chain of at least seven carbon atoms bonded to the carboxylic group, e.g., lauric, palmitic stearic, etc. Fats and fatty oils are glycerides of higher fatty acids including naturally occurring mixtures thereof. This subclass includes those derivatives or modifications of these substances as do not involve the destruction of the carboxylic group and also those modifications which involve the conversion of the carboxylic group into derivatives which upon hydrolysis reverts to a carboxylic group, e.g., salts, esters, amides, acid halides, etc.
