Sophorolipids: boosting surfactant sustainability

Biosurfactants are surfactants of microbial origin - from yeast, fungi or bacteria. Produced in nature for a variety of reasons, biosurfactants have multi-functional properties and benefits ready to be harnessed by formulators and product manufacturers.

Thanks to their hydrophilic head and hydrophobic tail; biosurfactants have the ability to lower surface tension at liquid interfaces, making them invaluable in both biological and industrial settings (Figure 1). 

As the world grapples with the challenges of sustainability and environmental awareness, biosurfactants have emerged as the next progression of sustainability for the industry and an important alternative to traditional surfactants and their first-generation bio-based alternatives.
