Title – C11C
FATTY ACIDS FROM FATS, OILS OR WAXES;
CANDLES;
FATS, OILS OR FATTY ACIDS BY CHEMICAL MODIFICATION OF FATS, OILS,
OR FATTY ACIDS OBTAINED THEREFROM.
Definition statement
This subclass covers:
- Methods and apparatus for preparation of fatty acids from fats, fatty oils, or
waxes; compositions thereof, e.g. alpha-eleostearic acid, alpha-linolenic acid,
etc.
- Refining the fatty acids; methods and apparatus therefor
- Fats, oils, or fatty acids by chemical modification of fats, oils, or fatty acids
obtained therefrom e.g. ester polyols, fatty acid alkyl esters, epoxidized rapeseed oil; methods and apparatus therefor
- Candles; compositions therefor, processes and apparatus for production thereof
Relationship between large subject matter areas
The use of fatty acids, fats, oils or waxes for different purposes should be
classified in appropriate application places places, e.g. using fatty acids esters
of higher fatty acids as emulsifiers should relate to B01F 17/06; using fatty acids
as active ingredients for mortars, concrete or artificial stone - to C04B 24/04;
using oils, fats, or waxes and derivatives thereof in cosmetics or toilet
1
preparations - to A61K 8/92; using fats, fatty oils, ester type waxes, higher fatty
acids, oxidized oils or fats as active ingredients for mortars, concrete or artificial
stone - to C04B 24/08; using fatty oil as lubricating composition base - to
C10M 101/04.
C07 covers production or working up chemically synthesized substances, e.g.
synthetic waxes, whereas subclass C11C covers synthesis of substances from
natural materials.
C11B covers the production, purification/refining, recovery from waste
material or working up of oils and fats (e.g. animal or vegetable oils). C11B
does not cover obtaining fatty acid or chemical modification of fats, oils or fatty
acid from fat, fatty oils or waxes, which are covered by C11C.
A23D covers edible oils or fats and composition thereof, e.g. margarines,
shortenings, cooking oils and provides for subject matter relating to working up
or preservation finished products. Obtaining or refining fatty acid or chemically
modified fat, oils or fatty acids including edible oils or fats are covered by
subclass C11C, e.g. hydrogenating is covered by C11C 3/12 .

Glossary of terms
In this subclass, the following terms (or expressions) are used with the meaning
indicated:
Fat
Solid triester of glycerol and (mostly) saturated fatty acids
Fatty acid
Any of a class of aliphatic monocarboxylic acids that form
part of a lipid molecule and can be derived from fat by
hydrolysis; nearly all fatty acids are built around a series of
carbon atoms linked together in a chain of 4 to 28 carbon
Esterification
A chemical reaction resulting in the formation of at least one
ester product.
Hydrogenation Chemical process that adds hydrogen atoms to an unsaturated
fat or fatty acid
Isomerisation
Process by which one molecule is transformed into another
molecule which has exactly the same atoms, but the atoms are
rearranged e.g. A-B-C → B-A-C, usually requiring special
conditions of temperature, pressure, or catalysts
Lipid
Any of a group of organic compounds, including the fats, oils,
waxes, sterols, and triglycerides, that are insoluble in water
but soluble in nonpolar organic solvents, are oily to the touch,
and together with carbohydrates and proteins constitute the
principal structural material of living cells.
Wax
Any of a group of substances composed of hydrocarbons,
alcohols, fatty acids, and esters that are solid at ordinary
temperatures. They are similar to fats, but are less greasy and
4
more brittle.
Synonyms and Keywords
In patent documents the following abbreviations are often used:
FA
Fatty acid
DE
Degree of esterification
In patent documents the following expressions/words "Fat", “Lipid” and
"Triglyceride " are often used as synonyms.
In patent documents the expression/word "---" is often used instead of "---"
which is used in the classification scheme of this subclass.
In patent documents the expression/word "---" is often used with the
meaning "---".
