Description

C11B covers industrial processes for producing, refining, and preserving fats, oils, waxes, and related lipid materials through mechanical pressing, solvent extraction, or recovery from waste sources. The classification encompasses treatment methods such as bleaching, deodorization, hydrogenation, and other purification techniques applied to animal and vegetable fats, fatty substances like lanolin, and natural oils. Also included are the production and processing of essential oils and perfume compositions derived from plant and animal sources. This subclass excludes detergent manufacture and candle production, which are separately classified within C11.
