Descrição geral

Rhamnolipid biosurfactants are glycolipids containing L-rhamnose and ß-hydroxyl fatty acids, with amphiphilic properties (both hydrophilic and hydrophobic). This rhamnolipid product has been purified from Pseudomonas aeruginosa and contains a mixture of rhamnolipids with fatty acids of varying tail length. They are highly biodegradable, non-toxic, and renewable. Functional roles include bioactive, surfactant and emulsifier. Rhamnolipids provide good detergency/foaming/wetting, stable microemulsion formation, and solubility under high alkalinity. They are mild with skin-friendly attributes. Surfactant and emulsion properties of rhamnolipids include reducing the surface tension of water to 25 to 40 mN/m, having a CMC of 5-380 mg/L, and decreasing the interfacial tension of oil and water to <1 dyne/cm. Rhamnolipid biosurfactants are superior to synthetic surfactants for several reasons: their CMC is 10-100 times lower than that of traditional chemical surfactants (meaning much less material is required to achieve reductions in surface tension/interfacial tension); they are easily biodegradable with very low toxicity (having higher EC50 values); they are not as affected by temperature, pH and salinity; and they are sustainably produced.

Aplicação

Rhamnolipids can be used in pharmaceuticals, cosmeceuticals, cosmetics, personal products, environmental bioremediation, the petroleum industry, household cleaners, food and beverage processing, agriculture and horticulture, therapeutics, nanotechnology, the polymer industry, cryo-protectants, the mining industry, biofuels, ethanol production, microbial fuel cells, protein research, and neural stem cell studies.
