Hercolyn DW (Hydrogenated Rosin)

CAS: 8050-15-5

Hercolyn® DW is widely recognized in perfumery as a hydrogenated methyl ester derived from pine rosin, commonly used as a solvent and fixative in fragrance and flavor formulations. The material is virtually odourless, though it may present an extremely faint balsamic-woody nuance with delicate ambery and resinous undertones reflecting its origin from natural pine resins.

It typically appears as a clear to nearly colourless liquid with noticeable viscosity, and is valued for its good resistance to oxidation and heat due to the hydrogenation process. Thanks to its low volatility and highly neutral olfactory profile, perfumers employ it as a technical ingredient that helps improve fixation, extend fragrance longevity, and balance the evaporation of lighter components. It also serves as an effective medium for dissolving resins, essential oils, and heavier aromatic materials without imparting a perceptible scent of its own.

Within the family of **rosin-derived fragrance solvents and fixatives—such as Hercolyn® D—**Hercolyn® DW is particularly appreciated for its excellent olfactory neutrality and clarity, making it especially suitable for compositions where transparency and stability of delicate aromatic materials are essential.
