Safety Profile
USE WITH AWARENESSWhat Does 3-Pentanone, 1-(2,6,6-trimethyl-2-cyclohexen-1-yl)-, reaction products with 2-propyn-1-ol Smell Like?
The scent profile presents an intriguing duality – opening with a crisp, almost metallic ketonic sharpness that quickly mellows into a warm woody-amber foundation. Imagine the first spark of a flint meeting polished teakwood, evolving into a suede-like softness with faintly sweet undertones. The dry-down reveals subtle tobacco-leaf nuances wrapped in an earthy muskiness, making it particularly valuable for adding textural complexity to modern woody compositions.
Chemistry, Properties & Perfumer Guide
The Chemistry
This material belongs to the class of modified cyclohexenyl ketones, created through the reaction of a trimethylcyclohexenone derivative with propargyl alcohol. The synthesis yields a mixture of reaction products including unsaturated ketones and alcohol derivatives. The exact structure varies between batches due to the complexity of the reaction pathway, which may involve Michael additions and subsequent rearrangements. This variability contributes to its nuanced olfactory profile.
