DEFINITION

Classification: 435/271

Glyceridic oil, fat, ester-type wax or higher fatty acid

recovered or purified:

(under subclass 267) Processes wherein the preexisting material is a fat, ester-type wax, higher fatty acid, or glyceride oil.

(1) Note. Fats and fatty oils are the glycerides of higher fatty acids, including naturally occurring mixtures thereof present in a single oil or fat.

(2) Note. Ester-type waxes are waxes which are essentially esters in chemical structure, e.g., beeswax, montan wax, carnauba wax, and spermaceti.

(3) Note. Higher fatty acid is a monocarboxylic acid containing an unbroken chain of more than seven carbon atoms bonded to a carboxylic group, e.g., lauric, palmitic, stearic, oleic, ricinoleic, linoleic acid, etc. Where there are several unbroken chains of carbon atoms bonded to the carboxyl group, one of the chains must contain a chain of seven or more carbon atoms.
