• 📂 CAS N° — 13019-22-2

• ⚖️ MW — 156.26 g/mol

• 📝 Odor type — Floral Rosy

• 📈 Odor Strength — High

• 👃🏼 Odor Profile — Fresh, green, aldehydic dewy rose note (IFF). characterized by a potent, fatty-oily, and waxy-rosy fragrance of remarkable tenacity. Notably, the rosy nuances become particularly pronounced at dilutions of 1% or lower, whereas higher concentrations yield more prominent waxy-oily notes.

• ⚗️ Uses — For use in floral, rose petal or herbal fragrances. imparts a waxy, aldehydic character without being fatty and maintains a constancy of odor strength. Despite its initial association with soap perfumes, this alcohol has found its way into various floral, refreshing, and sweet fragrance compositions, as well as modern detergent fragrances. Although fundamentally a rose-derived material, its versatility extends beyond traditionally rosy scents. When combined with isobutylquinoline and ionones, it serves as a "lifting" agent, offering intriguing effects when blended with Styrax materials.

Colorless and oily in its liquid state, this substance exhibits practical insolubility in water, yet demonstrates solubility in both alcohol and oils. Its olfactory profile is characterized by a potent, fatty-oily, and waxy-rosy fragrance of remarkable tenacity. Notably, the rosy nuances become particularly pronounced at dilutions of 1% or lower, whereas higher concentrations yield more prominent waxy-oily notes. This chemically simple alcohol, introduced in the late 1950s, has garnered substantial popularity.

Its commendable stability in soap perfumes and its remarkable floral radiance, especially when paired with aliphatic aldehydes, swiftly found application in highly successful soap fragrances recognized globally. Despite its initial association with soap perfumes, this alcohol has found its way into various floral, refreshing, and sweet fragrance compositions, as well as modern detergent fragrances. Although fundamentally a rose-derived material, its versatility extends beyond traditionally rosy scents. When combined with isobutylquinoline and ionones, it serves as a "lifting" agent, offering intriguing effects when blended with Styrax materials.

While the expiration of its manufacturing patent may suggest an influx of the material at a lower cost, widespread production remains unlikely due to the challenges associated with achieving odor purity and the complexities of large-scale manufacturing. In terms of its effects and overall character, this alcohol shares some similarities with higher, branched-chain aliphatic aldehydes such as Norhexahydrofarnesal.
