**Glossary:** - Essential oil: A concentrated, hydrophobic liquid containing volatile aromatic compounds from plants. - Esterification: Reaction between acid and alcohol resulting in ester bond. - Fat: Esters of glycerol and fatty acids, generally in solid form. - Fatty acid: A carboxylic acid consisting of a hydrocarbon chain, which may have unsaturations and a terminal carboxyl group. - Hydrogenation: Chemical process that adds hydrogen atoms to a molecule. - Isomerizing: Process by which one molecule is transformed into another molecule which has exactly the same atoms. - Lipid: Organic compounds based on fatty acids, generally hydrophobic. - Oil: Fat which is in liquid form. - Wax: Any of a group of substances composed of hydrophobic hydrocarbons, alcohols, fatty acids, and esters that are solid at ambient temperatures.
