CO2 Extracted Lavender Oil: A Supercritical Approach

Introduction

Lavender oil (Lavandula angustifolia) is widely known for its calming, anti-inflammatory, and antimicrobial properties. It is a key ingredient in aromatherapy, skincare, pharmaceuticals, and personal care products.

Traditional extraction methods, such as steam distillation and solvent extraction, often lead to loss of heat-sensitive aroma compounds, residual solvents, or degradation of active ingredients.

CO2 supercritical extraction (CO2 SUPERCRITICAL EXTRACTION MACHINE) provides a solvent-free, high-purity, and highly selective method to extract the full spectrum of lavender’s bioactive compounds, ensuring maximum therapeutic potency and aroma retention.

This article explores the CO2 extraction process, key parameters, experimental data, and industrial applications of lavender oil.

1. Principles of CO2 Supercritical Extraction of Lavender Oil

CO2 becomes a supercritical fluid when subjected to high pressure (>7.38 MPa) and temperature (>31.1°C). In this state, it has both gas-like diffusivity and liquid-like solubility, making it an ideal solvent for extracting lavender’s volatile oils, esters, and monoterpenes while preserving delicate aromatic notes.

The CO2 supercritical lavender extraction process consists of:...
