In the case of soil washing of metals, the Rhamnolipid carries a negative charge, so when the molecule encounters a metal such as lead that carries a positive charge, an ionic bond is formed that is stronger than the metal’s bond with the soil. Once this bond is formed, it is just a matter of pumping water through the soil to flush out the contaminant.
Rhamnolipid surfactant has a hydrophilic head that is attracted to water and another different hydrophobic head that repels water. This characteristic allows hydrocarbons “oils/grease” to be lifted to the surface and removed.
Since Rhamnolipids naturally occur at a contaminated soil site and since there are no harmful products of the natural breakdown of the Rhamnolipids, Rhamnolipids are a natural solution to hydrocarbon remediation.
Rhamnolipid Inc supplies a natural Biosurfactant that replaces current toxic surfactants. Our business is focused on customers that are replacing their current surfactants with our Rhamnolipid Biosurfactant. Our Biosurfactant is "green" environmentally safe and EPA approved.
Rhamnolipids are a type of biosurfactant, a surface-active substance synthesized by living cells. Like surfactants, they have the properties of reducing surface tension, stabilizing emulsions, and promoting foaming, but are environmentally-friendly and considered safer for being biodegradable and non-toxic. The replacement of surfactants with biosurfactants has been steadily increasing due to their diversity, environmentally-friendly nature, and their potential applications. The growth in these trends will result in large market potential for Rhamnolipids.
Synthetic Surfactants vs. Biosurfactants. Biosurfactants are superior to their synthetic "man made"- based counterparts: Lower toxicity; Higher biodegradability; Better environmental compatibility “Safe Technology”
Synthetic Surfactants are man made and mostly derived from petroleum products. They have been widely used in industry for many years as they work well and are inexpensive. However, synthetic surfactants also have a negative impact on the environment by leaving toxic by-products behind. These remaining by-products need to be retreated at a later time. Biosurfactants do not have this problem. It is a known fact that hydrocarbons cause health problems.
The annual surfactant demand in the United States is estimated to be 9.7 billion pounds. The largest end use market for surfactants is household cleaning detergents. These are comprised of large volume, lower priced laundry and dishwashing-detergent commodity products that account for roughly one-half of the U.S. surfactant market. “Specialty surfactants” are higher-priced, low-volume products used in a broad range of industrial and personal care market applications with annual demand estimated at 3.0 billion pounds or 26% of the total U.S. surfactant market.
