Creamy, milky, and warmly woody. Smoother and more linear than natural Mysore sandalwood, which has a richer, more animalic complexity. Polysantol leans slightly powdery with a lactonic warmth that reads as 'comfort.' Less dry than Javanol, less rosy than Bacdanol. The drydown is notably persistent -- a soft sandalwood halo that clings to skin for days.

The Full Story
Polysantol (CAS 107898-54-4) is a a Swiss fragrance house synthetic sandalwood molecule with one of the longest tenacities of any aroma chemical: 336-400 hours on a blotter strip. Its substituted cyclopentene alcohol structure produces a creamy, milky sandalwood character with musky undertones and faint cedarwood aspects.
Registered by a Swiss fragrance house in 1985, Polysantol was designed to address the growing scarcity and cost of Mysore sandalwood oil (Santalum album), whose supply collapsed as Indian sandalwood forests were depleted. Where natural sandalwood is rich, complex, and slightly animalic, Polysantol is cleaner and more linear -- a deliberate simplification that makes it easier to control in formulas.
The molecule is highly diffusive with exceptionally low volatility, making it effective in both fine fragrance and functional applications where persistence on fabric and skin is critical.
Polysantol lasts over 14 days on a paper blotter -- one of the longest-lasting single molecules in perfumery. This extraordinary persistence comes from its high molecular weight and low vapor pressure, which make it almost reluctant to evaporate.

Botanical Name
N/A — synthetic molecule (a Swiss fragrance house)
Polysantol is a base note sandalwood component used as either a primary sandalwood substitute or as a modifier to extend and brighten natural sandalwood oil. It functions as a fixative and structure-builder in woody, Amber, amber, and creamy floral compositions. Its extraordinary tenacity (300+ hours) makes it the backbone of long-lasting sandalwood accords. Used at 1-10% depending on the desired intensity.
