Rhamnolipids

Rhamnolipids are glycolipid biosurfactants produced through bacterial fermentation, primarily by Pseudomonas aeruginosa strains, consisting of one or two rhamnose sugar molecules linked to fatty acid chains. These naturally-derived surfactants offer exceptional mildness, antimicrobial properties, and environmental compatibility, making them increasingly popular in green cosmetic formulations. Formulators choose rhamnolipids for their ability to provide effective cleansing and emulsification while maintaining skin barrier integrity, plus their inherent antimicrobial activity can reduce the need for additional preservatives.
