What Is Cymbopogon, ext., oxidized?
Oxidized Cymbopogon extract is a processed version of lemongrass oil, used in fragrances to add depth and complexity. You might encounter it in citrus-forward perfumes or household cleaners. This ingredient matters because oxidation transforms the bright, grassy notes into richer, woody-amber tones that last longer on skin.
Safety Profile
USE WITH AWARENESSWhat Does Cymbopogon, ext., oxidized Smell Like?
Starts with a subdued citrus-grass character, quickly evolving into a warm, hay-like heart with hints of dried tobacco. The dry-down reveals an unexpected amber-woody depth, like sun-baked grasses turning golden in late summer. Unlike fresh lemongrass, the oxidized version carries a leathery nuance that blends seamlessly with woody bases.
Chemistry, Properties & Perfumer Guide
The Chemistry
Oxidized Cymbopogon extract contains transformed terpenes and sesquiterpenes from the original lemongrass oil. The oxidation process creates new oxygenated compounds including aldehydes and ketones. Industrial production typically involves controlled air exposure or chemical oxidants to develop the desired profile while minimizing unwanted degradation products.
