The recent spin-off Des Solutio resulted from the developed research on natural solvents, carried by the group of Professor Ana Rita Duarte and Doctor Alexandre Paiva. The company aims to develop safe and environmentally friendly products, based on Natural Deep Eutectic Solvents (NADES), which can replace other toxic organic solvents commonly used in the cosmetic area. NADES offer many benefits over those solvents, once they are entirely derived from natural compounds such as organic acids, amino acids and sugars, found in a wide range of plants.
