Basic Info
Rhamnolipid (CAS 869062-42-0): High-Performance Glycolipid Biosurfactant for Sustainable Formulations
Rhamnolipid is a premier glycolipid-type biosurfactant produced via controlled microbial fermentation. Structurally composed of rhamnose sugar moieties linked to beta-hydroxy fatty acid chains, this bio-based surfactant offers superior surface activity and interfacial tension reduction compared to traditional petroleum-derived surfactants like SLS or LAS.
Available in both liquid solution and concentrated powder forms, Rhamnolipid demonstrates exceptional thermal stability, salinity tolerance, and broad pH adaptability. It naturally serves as an eco-friendly primary surfactant, co-emulsifier, solubilizer, and wetting agent across personal care, industrial cleaning, agricultural adjuvants, and environmental remediation sectors.

ISO 9001:2015 & ISO 14001:2015: Manufactured under certified quality management and environmental protection standards.
USDA BioPreferred Program Compliance: Verified high bio-based carbon content sourced strictly from renewable agricultural substrates.
REACH Registration Dossier Support: Complete regulatory data packages available for compliant importing and distribution within European markets.
Technical Dossier Package: Every shipment is supported by SDS (GHS compliant), Certificate of Analysis (COA), Ecotox Evaluation Reports, and Non-GMO Strain Declarations.
Product Packaging
Our analytical testing protocol ensures batch-to-batch consistency and high chemical integrity prior to product release.
HPLC Analysis (Mono- to Di-Rhamnolipid Ratio): High-Performance Liquid Chromatography is utilized to verify the exact structural distribution of mono-rhamnolipids (Rha-C10-C10) and di-rhamnolipids (Rha-Rha-C10-C10) for target application performance.
Surface Tension & Interfacial Tension Measurement: Tensiometer testing ensures each production batch achieves the baseline reduction (<30 mN/m at 0.1 wt% concentration).
Active Matter Content Titration: Quantified via anthrone-sulfuric acid colorimetric assay and dry weight verification to ensure exact active concentration.
Microbial & Residue Testing: Strict monitoring of residual cell mass, heavy metals (ICP-OES), and organic solvent residues to ensure safety for personal care and agricultural uses.
pH & Viscosity Calibration: Standardized testing (10% aqueous solution) maintained within specified pH (6.0 – 7.5) and viscosity ranges for seamless integration into customer liquid lines.
Rhamnolipid is versatile and highly effective across diverse market segments:
Personal Care & Cosmetics: Acts as a mild, low-irritation secondary surfactant and foaming builder in natural shampoos, facial cleansers, and body washes, supporting “clean beauty” standards.
Eco-Friendly Household & Industrial Cleaning (I&I): Delivers powerful grease emulsification and hard-surface cleaning performance in eco-labeled detergents, degreasers, and glass cleaners.
Agricultural Formulations & Biopesticides: Functions as a natural adjuvant, improving droplet spreading, cuticular penetration, and active ingredient wetting on leaf surfaces.
Environmental & Microbial Enhanced Oil Recovery (MEOR): Reduces oil-water interfacial tension to assist in soil bioremediation, hydrocarbon washing, and heavy crude viscosity reduction.
Recommended Dosage Guidelines:
Personal Care formulations: 0.5% – 3.0%
Household cleansers / Degreasers: 1.0% – 5.0%
Agricultural tank-mix adjuvants: 0.1% – 0.5%
FAQ
A: Rhamnolipid achieves significantly lower Critical Micelle Concentration (CMC) values than SLES and alkyl polyglucosides (APG), meaning it achieves equivalent surface activity at lower dosage levels. Furthermore, it offers superior aquatic safety profiles and rapid biodegradation under varying environmental conditions.
A: Yes. Unlike conventional soaps, Rhamnolipid demonstrates excellent tolerance to divalent cations (Ca²⁺, Mg²⁺) and high sodium chloride concentrations (up to 10% NaCl), making it effective in marine applications and industrial hard-water cleansers.
A: Rhamnolipid should be stored in sealed original packaging at temperatures between 5°C and 30°C in a dry, dark warehouse. When kept under these conditions, the product maintains a stable shelf life of 24 months from the date of manufacture.
