CO2 Extraction for Perfumes: A Supercritical Approach

Introduction

The fragrance industry relies on high-purity natural extracts to create luxury perfumes, essential oils, and aromatic products. Traditional extraction methods such as solvent extraction (hexane, ethanol) and steam distillation often lead to residual chemicals, heat-induced degradation, and loss of volatile aroma compounds.

CO2 supercritical extraction (CO2 SUPERCRITICAL EXTRACTION MACHINE) provides a solvent-free, eco-friendly, and highly selective method for extracting delicate floral, herbal, and woody essences while preserving their natural aroma and therapeutic properties. This article explores how CO2 extraction is transforming the perfume industry, key parameters, experimental data, and industrial applications.

1. Principles of CO2 Supercritical Extraction for Perfumes

CO2 reaches its supercritical state at 31.1°C and 7.38 MPa, making it an ideal solvent for perfume extraction. In this state, CO2 has both gas-like diffusivity and liquid-like solubility, allowing it to gently extract aromatic compounds without high-temperature degradation.

The CO2 supercritical extraction process consists of:...
