General description

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.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for hydrocarbon degradation. For more information see the paper Environmental applications of biosurfacants: recent advances, and the many other articles available at: AGAE Technologies

Application

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.

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
