Walnut Leaves CO₂ Total Extract is a concentrated botanical material obtained from the leaves of Juglans regia, commonly known as English Walnut or Persian Walnut.
Produced through supercritical CO₂ extraction, this total extract captures a rich, naturally variable fraction of the leaf, including green botanical compounds, waxes, pigments, and aromatic constituents. It brings a deep herbal character and a distinctive dark green-to-brown color to oil-based cosmetic and botanical formulations.
Walnut Leaves CO₂ Total Extract is especially suited to formulators seeking an unusual leaf-derived ingredient for botanical facial oils, hair oils, scalp blends, balms, salves, massage oils, beard oils, anhydrous skincare, and artisan soap or body-care concepts.
Published research on Juglans regia leaf CO₂ extracts has identified naturally occurring polyphenols and juglone-related compounds.
