Ambrette Seed Absolute

#### Ambrette Seed Absolute. A "true-to-the-name" **Ambrette**** ****Seed**** ****Absolute**** **can be produced from the true **Concrète**** **(see below) by alcohol washing of the lukewarm concrète, followed by chilling and filtering of the alcoholic extracts. After evaporation of the alcohol, a colorless to pale yellow liquid oil is left: this is **Ambrette Seed Absolute**. Commercial **Ambrette Seed Absolute **is not produced by this method. It is produced from the essential (distilled) oil either by neutralization and subsequent elimination of the fatty acids, or it is steam distilled from the extracted (true) concrète. In other words, the absolute is the essential oil minus the fatty acids which are solid and insoluble in cold alcohol. They also tend to produce a rancid odor in ambrette seed oil upon ageing. **Ambrette Seed Absolute **is thus not a true absolute according to the definitions in this book. It is somewhat similar to an **Absolute Oil. **Various suppliers will supply quite different products. Application and odor description fall generally within the notes given in the monograph on **Ambrette Seed Oil**, see below. ---
