Absolutes: Alcoholic extraction of concretes to remove waxes, terpenes, sequiterpenes and most odorless materials, which yields an alcohol-soluble liquid or semi-liquid oil.

Botanical Extract: A botanical extract is an extract of a botanical substance manufactured with potable solvents such as Ethyl Alcohol, Propylene Glycol and water. They are somewhat dilute and may contain all or part of the extracting solvent. Botanical extracts are divided into categories based on their production methods. There are native extracts, solid extracts, fluid extracts, tinctures hydroglycolic extracts and glycolic extracts. Vanilla is considered a botanical extract.

Concretes: Extraction of fresh plant materials (typically flowers, buds, leaves), usually with a non-polar organic solvents (hexane, benzene, acetone), which yield after the removal of the solvent by vacuum distillation a fatty solid or semi-solid fragrant waxes.

Distillation: A physical technique for the separation and purification of a liquid mixture (often essential oils) based on the differences in vapor pressure of components in the mixture. The process involves vaporization of the components and then condensation of the vapor back into a liquid.

Essential Oils: The volatile products obtained by distillation or expression of plant material from a single natural botanical. Essential oils can be found in the roots, seeds, leaves, flowers, stems and the peel of the fruit of many botanicals.

Oleoresin: Extractions of botanicals using selected non-potable solvents such as Acetone, Hexane or Ethylene Dichloride to remove volatile and non volatile flavor, color, heat and pungent components. The solvent containing the extracted material is then filtered and the solvent removed.

Terpenes: Fractions from essential oils consisting mainly of hydrocarbons obtained as by-products from either concentration or fractional distillation of the oils.
