Camellia leaf CO2 extract
CAS 68916-73-4
What Is Camellia leaf CO2 extract?
Camellia leaf CO2 extract is a luxurious natural ingredient obtained through supercritical carbon dioxide extraction of Camellia sinensis leaves, the same plant used for tea. It’s found in high-end skincare and niche perfumery. This extract captures the plant’s delicate green character without solvent residues, making it prized for its purity and authentic botanical signature.
Safety Profile
GENERALLY SAFEWhat Does Camellia leaf CO2 extract Smell Like?
The aroma unfolds with a dewy, chlorophyll-rich top note reminiscent of crushed tea leaves at dawn—vibrantly green with a faint astringency. As it settles, a heart of delicate floral undertones emerges, like jasmine-steeped oolong tea, wrapped in a subtle earthy base. The dry-down reveals a soft, slightly tannic woodiness that lingers close to skin, creating an intimate botanical aura.

Chemistry, Properties & Perfumer Guide
The Chemistry
Camellia leaf CO2 extract contains a complex mixture of polyphenols including catechins (particularly epigallocatechin gallate), chlorophyll derivatives, and volatile terpenes like linalool. The supercritical CO2 process selectively extracts non-polar compounds at low temperatures, preserving heat-sensitive components. This differs from steam-distilled versions which lose the fresh green character.
