FATTY ACIDS FROM FATS, OILS OR WAXES; CANDLES; FATS, OILS OR FATTY ACIDS BY CHEMICAL MODIFICATION OF FATS, OILS, OR FATTY ACIDS OBTAINED THEREFROM

Description

C11C covers the extraction, isolation, and chemical transformation of fatty acids from natural sources (fats, oils, and waxes), as well as the manufacture of candles and chemically modified lipid products. This includes hydrogenation, oxidation, esterification, and other chemical processes that alter the properties of fatty substances for industrial or consumer applications. The classification encompasses both traditional candle production and modern derivatives used in pharmaceuticals, cosmetics, lubricants, and food additives, excluding crude oil refining and purely physical separation processes covered elsewhere in C11.
