bio surfactant

Rhamnolipids are bio surfactant naturally occurring glycolipids produced commercially by the Pseudomonas aeruginosa species of bacteria. P. aeruginosa produces both mono-rhamnolipids and di-rhamnolipids. Many strains of P. aeruginosa can produce rhamnolipids both aerobically and in some cases by anaerobic fermentation. Rhamnolipids function as a natural surfactant, emulsifier, fungicide, and antibiotic.

In pure form, rhamnolipids are a white powder when desiccated. Generally rhamnolipids are supplied and used in an aqueous solution. The solution may range from clear to milky white or tan in color, depending on concentration and purification. When used as a surfactant, only low concentrations are necessary.

As a natural “green”, non-carcinogenic product, rhamnolipids are just now beginning to be used to replace petroleum-based chemicals in cosmetics, soaps, shampoos, detergents, pharmaceuticals, agricultural sprays, etc. as those currently used petrochemicals are being phased out or banned.
