Synonyms: Dihydroambrettolide, Juniper Lactone, Hexadecanolide Classification: Base Note[i]
Onestolide (high purity Dihydroambrettolide) opens with a sophisticated sweet muskiness that immediately distinguishes itself through its balsamic richness and distinctive animalic undertones. This macrocyclic lactone presents a fascinating duality—simultaneously clean and animalic—creating depth without heaviness. The crystalline, vibrant quality particularly characteristic of Synarome's 98% grade adds luminosity to its inherent warmth.
Use Onestolide when you need exceptional fixation combined with character. Its remarkable diffusion enhances delicate florals without overpowering them, while its animalic facets create sensual depth in amber accords. This material excels at bridging modern clean aesthetics with classical warmth, making it indispensable for contemporary oriental compositions.
Combine with Aerolide®, Exaltolide or ethylene brassylate for complex musk accords. It harmonises beautifully with methylionones, vetiver derivatives, and aldehydes, while lending crucial support to labdanum and vanilla in amber bases.
Dihydroambrettolide vs Ambrettolide
The key distinction between Dihydroambrettolide and its unsaturated cousin Ambrettolide lies in their fundamental olfactive characters. While Ambrettolide presents pronounced floral and fruity facets with red fruit sweetness reminiscent of ambrette seeds, Dihydroambrettolide shifts the balance toward animalic warmth and balsamic depth.
Where Ambrettolide might lift a composition with botanical muskiness, Dihydroambrettolide grounds it with sensual warmth, making it the preferred choice for amber fragrances and compositions requiring direct, less "botanical" musk character.

General Information
General Information
Like most suppliers and makers of quality raw materials for fragrances, we do not filter many of our products. This ensures that no odiferous matter is lost prior to use but can result in the appearance of small particles or slight clouding.
All alcoholic fragrances should be macerated for up to a month and then chilled in a moderate freezer overnight before being filtered fine. This will remove all cloudiness or detritus and is the industry norm.
