1-Propoxypropan-2-ol (CAS 1569-01-03) — Sweet Carrier Note Fragrance Ingredient
1-Propoxypropan-2-ol
CAS 1569-01-03
What Is 1-Propoxypropan-2-ol?
1-Propoxypropan-2-ol is a synthetic solvent used in industrial applications and some specialty fragrances. It’s rarely encountered by consumers directly but may appear in technical formulations. This ingredient matters primarily for its solvent properties rather than as a fragrance material, though it can influence scent diffusion in complex mixtures.
Safety Profile
USE WITH AWARENESSWhat Does 1-Propoxypropan-2-ol Smell Like?
1-Propoxypropan-2-ol has a faint, ethereal odor with subtle solvent-like characteristics. The scent profile is clean and slightly sweet, reminiscent of diluted alcohol with a whisper of plastic undertones. It lacks distinct top/middle/base evolution, presenting a linear olfactory character that serves primarily as a carrier rather than a fragrance note.
Chemistry, Properties & Perfumer Guide
The Chemistry
1-Propoxypropan-2-ol is a simple ether-alcohol compound synthesized through the reaction of propylene oxide with propanol. As a synthetic material, it doesn’t occur naturally. The molecule features both ether and hydroxyl functional groups, giving it moderate polarity and solvent properties. Its structure suggests potential as a fragrance carrier solvent rather than an impactful odorant.
