Vegetable fats waxes

Natural products Vegetable oils waxes, mineral oils plus their sulfated derivatives (including those of animal oils and fats) Sugar extraction glue manufacture cutting oils... 

NOTE There are various types of organic contaminants that can be present in boiler FW, including trace amounts of pesticides and naturally occurring humic, fulvic, and tannic acids, and solvent-extractable oily matter, such as nonvolatile hydrocarbons, vegetable oils, animal fats, waxes, soaps, greases, and the like. 

Traditionally, dried or powdered plant material is used and extracts can be obtained by mixing the material with food-grade solvents like dichloromethane or acetone followed by washing, concentration, and solvent removal. The result is an oily product that may contain variable amounts of pheophytins and other chlorophyll degradation compounds usually accompanied by lipid-soluble substances like carotenoids (mainly lutein), carotenes, fats, waxes, and phospholipids, depending on the raw material and extraction techniques employed. This product is usually marketed as pheophytin after standardization with vegetable oils. 

Fatty acids, their glycerides and other esters, including fats, waxes and oils such as mineral and vegetable oils fatty alkylamines and acylamides. Alkaline earth metal or aluminium salts of fatty acids tend to leave deposits on machinery [536]. 

Cotton, Chemical, The basic raw material from which NC and cellulose acetate are made. Chemical cotton is chemically purified cotton linters (See under). The raw linters contain impurities such as proteins, fats, waxes, pectins, sugars, inorganic salts and mechanically entrapped vegetation, dirt, wood etc, all of which must be removed... 

Extraction from vegetation may produce complicated sample extracts, because organic plant material (fats, waxes, resins, etc.) will be dissolved as well. Before GC/MS analysis of these samples, a cleanup step is usually performed to remove compounds originating from the matrix. Injection of resins, typically organic acids, could degrade the GC performance dramatically. 

Analytical methods for determining the authenticity of vegetable fats have classically been based on comparison of the composition of some major and minor components. For the most important traded oils, tables of the composition (i.e. profiles) of the major fatty acids and sterols have been of importance and have in some cases been supported by data describing other components such as triacylglycerols, sterol esters, volatiles, waxes and fatty alcohols.
