✦ Synopsis

Biosurfactants from urban wastes

Six biosurfactants (BS) isolated from green and urban food residues under aerobic digestion for 0-60 days were investigated for chemical composition, surface activity properties and detergent performance in fabric washing and were compared with commercial anionic and non-ionic surfactants (CS). BS and CS have similar performance when used neat but 1:1 mixes show significant synergy. The results indicate that when used above critical micellar concentration no critical difference was evident between the BS and CS. These observations encourage expectation for industrial application and commercialisation of BS as components of detergent formulations.
