Safety Profile
GENERALLY SAFEWhat Does Peppermint oil, terpeneless Smell Like?
Terpeneless peppermint oil offers a crisp, clean mint aroma with reduced camphoraceous notes. The scent evolves from an initial sharp, almost icy freshness to a smoother, sweeter heart with subtle herbal undertones. Unlike regular peppermint oil, the dry-down is more stable and less medicinal, lingering as a soft minty whisper rather than fading abruptly.

Chemistry, Properties & Perfumer Guide
The Chemistry
Terpeneless peppermint oil is produced by removing the monoterpene hydrocarbons (like limonene and pinenes) from regular peppermint oil through fractional distillation or solvent extraction. This process increases the relative concentration of oxygenated compounds like menthol and menthone, which are responsible for the characteristic minty aroma. The result is a more stable and longer-lasting fragrance material.
