RHAMNOLIPID PROPERTIES
Numerous properties of rhamnolipids make them suitable for many applications.
Many of their properties, such as their versatility and their ability to perform deter-
gency; their foaming, wetting, emulsifying, demulsifying, solubilizing, and thick-
ening; as well as their solubilizing, dispersing, metal sequestering, vesicle forming
and phase dispersion; antimicrobial activities against both phytopathogenic fungi
and bacteria; and also their thermostability and ecological compatibility, outperform
other biosurfactants and synthetic surfactants. These properties make rhamnolipids
