Rhamnolipid

Suzhou Rhamnolipid Manufacturer Direct Sales, Guaranteed High Quality

Rhamnolipid is a biosurfactant produced by bacterial fermentation and is currently one of the most extensively researched biosurfactants with broad application prospects. It is a water-soluble anionic surfactant with functions such as reducing surface tension, solubilizing, emulsifying, demulsifying, defoaming, washing, dispersing and flocculating, penetrating, and wetting. Rhamnolipid has strong surface activity, requires small dosages, and has excellent compatibility with other surfactants. Additionally, it offers advantages such as being non-toxic, chemically stable, temperature and salt-resistant, and biodegradable, making it an environmentally friendly and sustainable alternative product.

Product Functional Category and Applications
1. Petroleum Industry: As a biosurfactant, it reduces oil-water interfacial tension and is used in tertiary recovery techniques after primary and secondary oil recovery to enhance oil recovery rates. Used as a sacrificial agent to reduce the dosage or loss of expensive oil-displacing agents in formations. When compounded with other oil-displacing agents, it offers effective oil displacement with long-lasting results. The addition of rhamnolipid effectively reduces the amount of oil-displacing agent required, significantly lowering costs. 2. Agriculture: It promotes nutrient absorption in crops, improves soil environment, increases yield and income, and prevents certain pests and diseases. Rhamnolipid can serve as an effective method for plants to absorb heavy metal ions from soil, making it a good approach for in-situ treatment of heavy metal-contaminated soil using phytotechnology. As a wetting agent, added to foliar fertilizers to improve wetting conditions on waxy layers, allowing fertilizers to spread fully and promoting absorption and utilization. 3. Food Industry: Can be used for the storage of baked goods. Improves the stability of whipped cream and decorative cream, as well as the stability of non-dairy cream fillings in Danish pastries, croissants, and other fresh or frozen refined sugar-containing foods. For fruit and vegetable preservation, it mainly functions as a coating agent. When applied to the surface of fruits and vegetables, it forms a film that prevents oxygen from entering, creating a low-oxygen micro-environment within the film, reducing respiration, and thereby extending the storage period of fruits and vegetables. 4. Pharmaceutical Manufacturing: Can be used to accelerate wound healing and reduce scarring. It is effective for skin diseases such as dermatitis. Also used as coatings for stents, implants, prosthetics, and bandages. 5. Daily Chemical Industry: Facilitates the diffusion of substances through dispersing and wetting properties. Helps retain moisture, lubricate, and generate foam; maintains system stability of mixtures, controls product viscosity, and emulsifies oils in pores.
