Description de la ressource pédagogique
Description (résumé)
New products containing active substances from the plants are systematically appearing on the cosmetics market. Among others natural products, based on raw materials that meet the standards set for natural 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.
