Description

Surfactin is a powerful cyclic lipopeptide biosurfactant produced by various strains of *Bacillus subtilis*. This compound matters for its exceptional surface-active properties, high biodegradability, and low toxicity, making it a superior and sustainable alternative to many synthetic surfactants. Industries that need it include biotechnology, pharmaceuticals, agriculture, and personal care, where it is valued for its antimicrobial, antiviral, and emulsifying capabilities. Its versatility and natural origin align with the growing demand for green chemistry solutions.

Application

• Enhanced Oil Recovery (EOR): Used as a highly effective and environmentally friendly biosurfactant to reduce interfacial tension and mobilize trapped crude oil.
• Pharmaceutical Formulations: Employed for its potent antimicrobial and antiviral activities in developing therapeutic agents and as a stabilizing agent in drug delivery systems.
• Bioremediation: Facilitates the degradation of hydrophobic pollutants like hydrocarbons and heavy metals by increasing their bioavailability to microorganisms.
• Agricultural Biocontrol: Acts as a natural fungicide and elicitor of plant defense responses, promoting sustainable crop protection.
• Cosmetics & Personal Care: Serves as a high-performance, skin-compatible emulsifier and foaming agent in creams, lotions, and cleansers.
• Food Processing: Utilized as an emulsifier and antimicrobial preservative, often in biofilm removal and sanitation processes.
• Nanotechnology: Aids in the synthesis and stabilization of nanoparticles due to its excellent surface-modifying properties.
• Industrial Cleaning: Formulated into "green" detergents and degreasers for hard surface cleaning.

Quality Control

Our Surfactin is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay, critical impurities, and biological activity. Quality standards are aligned with cGMP principles where applicable, supporting use in pharmaceutical and advanced industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture. Keep away from strong oxidizing agents.
