| Résumé : |
Surfactants are the most important ingredients in laundry detergents, hand dish washing liquids and shampoos. It is a major challenge for the industry today to identify alternative materials that are biodegradable, based on renewable resources and that show reasonable cost-performance effectiveness. Biosurfactants are an emerging class of surfactants produced by microorganisms in processes usually running at low temperatures and without large amounts of waste or by-products, therefore complying with the rules of green chemistry and potentially resulting in a lower carbon footprint than conventional surfactants. We show in our work which biosurfactants can meet or even surpass conventional surfactants today when it comes to properties like interfacial tension reduction and wetting. Taking into account that further optimization and tailoring of materials, unique physicochemical properties and efficient production processes are within reach, the future perspectives for the broader use of biosurfactants are bright. |
