DEFINITION

Classification: 507/265

Organic component is a fat, fatty alcohol, fatty oil, ester-type wax, fatty still residue, or higher fatty acid or salt thereof:

(under subclass 203) Compositions wherein the organic component is a fat, fatty alcohol, fatty oil, ester-type wax, fatty still residue, or higher fatty acid, including salts thereof.

SEE OR SEARCH THIS CLASS, SUBCLASS:

218, for carbohydrate esters of fatty acids.

263, for tall oil, rosin, rosin acids, resin acids, abietic acids, and other organic components containing carbocyclic groups.

ESTER-TYPE WAXES

Waxes which are essentially esters in chemical structure (e.g., beeswax, montan wax, carnauba wax, spermaceti, etc.).

FATTY STILL RESIDUES Intended to include the bottoms, tars, or pitches resulting from distillation of fats, oils, and waxes.

FATS and FATTY OILS

The glycerides of higher fatty acids, including naturally occurring mixtures thereof present in a single oil or fat.

FATTY ALCOHOL

An alcohol containing an unbroken chain of at least seven carbon atoms bonded to a hydroxy group.

HIGHER FATTY ACID

A monocarboxylic acid containing an unbroken chain of at least seven carbon atoms bonded to a carboxyl group (e.g., lauric, palmitic, stearic, oleic, ricinoleic, linoleic, and behenolic, etc.). Where there are several unbroken chains of carbon atoms bonded to the carboxyl group, one of the chains must contain at least seven carbon atoms.
