BIOCOMPATIBLE SURFACTANTS AND IONIC LIQUIDS
Group Leader: Aurora Pinazo
Chemistry is currently facing one of the greatest challenges in its history. Environmental concern and regulatory pressure have provided the driving force to try to replace petrochemical-based compounds with those based on naturally occurring renewable sources. Addressing this challenge involves investigating for how renewable resources can be used in the synthesis of new biocompatible compounds.
Since it is well known that surface-active compounds can adversely affect the aquatic environment, there is a clear trend to move towards non-toxic biodegradable renewable raw materials as building blocks for the synthesis of non-polluting biocompatible surface-active compounds. Our group conducts a comprehensive research on novel surfactants and ionic liquids derived from natural renewable sources like amino acids and natural oils. The goal is to develop biocompatible compounds with low toxicity and high biodegradability. Surfactants and ionic liquids with these properties would fulfill the requirements of industries in the food, cosmetics and pharmaceutical field.
