In the pursuit of sustainable development today, a natural biosurfactant called rhamnolipids is quietly changing the development trajectory of the cleaning and personal care industry. This natural molecule produced by microbial fermentation not only exhibits excellent surface activity, but also carries the core concept of green chemistry, bringing new solutions to the industry.
The crystallization of natural wisdom: understanding rhamnolipids
Rhamnolipids are secondary metabolites produced by Pseudomonas bacteria through fermentation processes. Its molecular structure contains hydrophobic fatty acid chains and hydrophilic rhamnose rings, giving it excellent surface activity due to its unique amphiphilic structure. Compared with traditional petroleum based surfactants, rhamnolipids have the following natural advantages:
·100% biobased content, renewable source
·Biodegradable and environmentally compatible
·Low ecological toxicity, safe for aquatic organisms
·Low carbon footprint during production process
Excellent performance: surpassing traditional performance
1. Extraordinary surface activity
Rhamnolipids can reduce the surface tension of water from 72 mN/m to below 30 mN/m, which is superior to many synthetic surfactants. Its critical micelle concentration (CMC) is extremely low, which means that a small amount can achieve significant effects.
2. Gentle cleaning characteristics
Wide pH adaptability (4.0-8.0), good compatibility with the skin, and no excessive degreasing. This characteristic makes it particularly suitable for use on sensitive skin, avoiding the irritation problems that traditional surfactants may cause.
3. Multi functional integration
In addition to surface activity, it also possesses:
·Antibacterial and anti biofilm activity
·Emulsification stabilization function
·Solubilization performance
·Antioxidant properties
Innovative Applications: Redefining Cleaning and Care
Home cleaning field
High end detergent: effectively removes oil and fat, with biodegradable properties to avoid eutrophication of water bodies
Multi functional cleaner: excellent cleaning performance on hard surfaces while inhibiting microbial regeneration
Fruit and vegetable cleaning agent: removes pesticide residues, certified by authoritative institutions for safety
Industrial cleaning agents: used in special fields such as oil and gas industry, environmental remediation, etc
Personal care innovation
Gentle cleansing product: pH value similar to the skin, maintaining the integrity of the skin barrier
Scalp care shampoo: effectively cleanses while inhibiting excessive growth of Malassezia bacteria
Oral care products: destroy the biofilm structure of dental plaque and reduce the occurrence of tooth decay
Functional skincare products: developing acne removal products using their antibacterial properties
Technical advantage: Why choose rhamnolipids?
1. Significant synergistic effect
When combined with other surfactants, it can produce a "1+1>2" effect. Research has shown that compounding with amino acid surfactants can further improve mildness, while compounding with anionic surfactants enhances cleaning power.
2. Excellent stability
Good resistance to hard water, maintaining stability over a wide temperature and pH range, facilitating product formulation design.
3. Outstanding security
Skin and eye irritation tests have confirmed its mild properties, and ecotoxicity data shows that it is environmentally friendly.
Production Technology and Sustainable Development
·The development of modern biotechnology has greatly improved the production efficiency of rhamnolipids:
·Using renewable carbon sources (such as waste oil) as fermentation substrates
·The fermentation process has high carbon efficiency and low waste generation
·The downstream extraction process is continuously optimized, and the purity can reach over 95%
·Production costs continue to decline, competitiveness continues to strengthen
