Ebanol (CAS 67801-20-1) — sandalwood base Note Fragrance Ingredient
Ebanol
CAS 67801-20-1
What Is Ebanol?
Ebanol is a synthetic sandalwood-like fragrance ingredient used in perfumes and personal care products. It provides a warm, woody foundation to many modern fragrances. This versatile material helps create long-lasting scent profiles, particularly in woody and oriental fragrance families where sandalwood notes are desired but natural sandalwood is restricted or unavailable.
Safety Profile
USE WITH AWARENESSWhat Does Ebanol Smell Like?
Ebanol delivers a rich, creamy sandalwood character with remarkable tenacity. Upon first application, it presents a slightly sharp woody-alcohol top that quickly mellows into a velvety sandalwood heart. The dry-down reveals its true magic – a persistent, slightly sweet woody base with facets reminiscent of aged sandalwood oil. Compared to natural sandalwood, Ebanol offers more consistency and projection, though lacks some of the natural oil’s milky-soft nuances. It blends beautifully with vanilla, patchouli, and musks to create luxurious woody foundations.

Chemistry, Properties & Perfumer Guide
The Chemistry
Ebanol is a synthetic sandalwood substitute belonging to the class of decalin derivatives. While its exact structure is proprietary, it shares structural similarities with natural sandalwood components like α-santalol. The synthesis typically involves catalytic hydrogenation of appropriate aromatic precursors to create the saturated decalin framework that provides the woody character. Unlike natural sandalwood oils which contain multiple santalols, Ebanol offers a single-molecule consistency that makes it valuable for standardizing sandalwood accords in modern perfumery.

IFRA Status
No specific restrictions under current IFRA standards (as of 49th Amendment).
GHS Classification
RIFM Assessment
RIFM has evaluated Ebanol and found it safe for use at current industry levels in fragrance applications.
Sustainability
As a synthetic material, Ebanol provides a sustainable alternative to natural sandalwood, which faces conservation challenges. Its production doesn’t rely on endangered sandalwood trees and offers consistent quality with lower environmental impact than wild-harvested natural materials. However, as a petrochemical derivative, its production does involve standard industrial chemistry processes.
