Concentrated Rhamnolipid Formulations: Bridging Chemodiversity to Structure, Flow Behavior, and Functionality.

ABSTRACT: The development of ultraconcentrated biobased formulations is one of the latest frontiers in sustainable product design. This study demonstrates that biosurfactants are well suited to the scope with their natural chemodiversity being a key factor in optimizing formulation structure and function. The composition of a low-cost commercial rhamnolipid sample was investigated by using nuclear magnetic resonance and mass spectrometry. The results revealed a complex mixture of congeners with a predominance of dirhamnolipids and double-tailed species and the presence of long-chain free fatty acids. Polarized optical microscopy, small-angle X-ray scattering, and electron paramagnetic resonance show that this rhamnolipid sample, in aqueous solution, forms ellipsoidal micelles with a highly hydrophob
