Descriptif
New products containing active substances from theplants are systematically appearing on the cosmetics market. Among othersnatural products, based on raw materials that meet the standards set fornatural and organic cosmetics (COSMOS), are becoming more and more popular.
The extracts obtained under supercritical CO2 conditions (SC-CO2) are an interesting alternative to plant extracts obtained by traditional methods. The parameters of the SC-CO2 process allow to obtain extracts of very high purity, free from contamination with conventional solvents. Additionally, relatively low temperatures and anaerobic atmosphere during the process, avoid oxidation and thermal decomposition of the bioactive components contained in the plant extracts, such as: triglycerides of essential fatty acids (EFAs), phospholipids, tocopherols, carotenoids, phytosterols or phytohormones.
