Green surfactants not only exhibit desirable physicochemical characteristics of chemically produced surfactants but also possess the virtues of being safe and capable of decomposition, making their use captivating. CD BioSciences-GreenChemistry, as one of the leading companies in green chemistry, employs experienced chemists who provide custom green surfactant manufacturing services that assist clients in performing surfactant optimization, protecting the environment, and achieving set sustainability targets.
Surfactant is an important class of chemical raw material, which occupies a special and important position in many fields such as the petroleum industry, environmental engineering, the food industry, the fine chemical industry, and so on. Eco-friendly surfactants that originate from bio-resources and are biodegradable are referred to as green surfactants. The use of green surfactants reduces environmental burdens while enhancing mixing and cleaning efficiency by lowering viscosity at the liquid interface. Eco-friendly surfactants are biodegradable, making them usable in contrast to conventional surfactants, but share the same purpose of reducing liquid surface tension, stabilization of emulsions, and increasing bubbling.

CD BioSciences-GreenChemistry is committed to providing professional green surfactant production services to our clients. Depending on the specific needs of clients, we offer a variety of environmentally friendly production methods to ensure the efficiency and sustainability of the entire production process, as well as the performance and safety of the surfactants in various applications. The main green production methods we offer include, but are not limited to, the following.
We use bio-enzymes as catalysts to facilitate the reaction of bio-based raw materials under mild conditions to produce green surfactants. This method avoids the use of toxic chemicals and usually consumes less energy. Based on this method, we produce green surfactants such as glycolipid-based surfactants, protein-based surfactants, and fatty acid salt-based surfactants.
We use renewable agricultural waste as raw materials and employ specific microorganisms (bacteria, yeasts, fungi, etc.) to synthesize surfactants in a fermentation process. This method is commonly used for the production of bio-based surfactants. For example, Pseudomonas aeruginosa fermentation is used to produce glycolipid surfactants, and Rhodococcus erythropolis fermentation is used to produce fatty acid and phospholipid surfactants.
Based on reducing our dependence on petrochemical source materials, we extract or synthesize surfactants from renewable sources such as vegetable oils and natural fats. The surfactants we produce using this method are not limited to sulfonated fatty acid methyl esters, vegetable-based surfactants, and succinic acid-based surfactants.
With the assistance of a skilled team of chemists and advanced technologies, CD BioSciences-GreenChemistry, as an emerging firm within the field of green chemistry, is equipped to deliver services in the area of green surfactant production. To ensure the maximum safety standards of bio-green surfactants, we employ the most suitable methods that best fulfill our clients' eco-friendly needs. We provide a variety of convenient communication methods, you can contact us at any time to realize efficient cooperation.
