Directory Guidance on Lactonic Sophorolipid
Chemical Structure
Basic Info
Lactonic Sophorolipid is a naturally occurring glycolipid biosurfactant produced through the biotechnology fermentation of non-GMO vegetable oils and sugars using Candida bombicola. Composed of a hydrophobic fatty acid tail and a hydrophilic sophorose head closed in a ring structure, the lactonic form exhibits exceptionally high surface activity, significantly lower critical micelle concentration (CMC), and distinct physical properties compared to its acidic counterparts.
Designed for eco-conscious personal care, green household cleaning, and specialized industrial formulations, Lactonic Sophorolipid offers superior surface tension reduction, natural self-preserving synergy, and 100% ultimate biodegradability. It serves as an advanced bio-based alternative to traditional petroleum-derived surfactants.

To accommodate the growing global demand for transparent, green chemistry, our Lactonic Sophorolipid is produced under audited biomanufacturing conditions.
ISO 9001:2015 & ISO 14001: Quality and environmental management alignment across the entire fermentation, downstream separation, and purification chain.
Readily Biodegradable Compliance: Meets OECD 301B guidelines for rapid, complete environmental breakdown into carbon dioxide and water.
Cosmetic Safety & Natural Standards: Aligned with international green cosmetic criteria (such as COSMOS / ECOCERT compliance frameworks) for bio-based origin content.
Technical Dossier Support: Complete regulatory documentation available on request, including GHS-compliant Safety Data Sheets (SDS), Batch Certificate of Analysis (COA), Non-GMO Statement, and Allergen/Heavy Metal Declarations.
Product Packaging
To guarantee batch-to-batch consistency and high structural purity of the lactonic fraction, each production batch undergoes strict multi-point analytical screening:
Lactonic vs. Acidic Ratio Determination (HPLC): Analyzed via High-Performance Liquid Chromatography (HPLC) with Evaporative Light Scattering Detection (ELSD) to ensure the specific lactonic ester fraction meets target specification.
Active Matter Content: Verified via dry weight moisture balance and gravimetric assays to maintain precise active glycolipid concentration.
Surface Activity Measurement: Tested via Wilhelmy plate tensiometry to confirm surface tension reduction performance prior to packaging.
Microbiological Quality Assurance: Screened for total viable count (TVC), yeast, and molds according to ISO 17516 standards, ensuring bio-burden safety for sensitive formulations.
Residual Media & Heavy Metal Analysis: Atomic Absorption Spectroscopy (AAS) is utilized to ensure zero trace contaminants from raw fermentation media.
Lactonic Sophorolipid offers versatile performance across high-value bio-based sectors:
Personal Care & Skincare Formulations: Functions as a mild secondary co-surfactant and skin-soothing agent in facial cleansers, anti-blemish serums, and scalp care shampoos.
Oral & Hygiene Products: Utilized for its natural anti-adhesion surface properties and gentle nature in oral care preparations and feminine hygiene washes.
Natural Household & Industrial Cleaning: Serves as a low-foaming, highly effective degreasing agent in hard-surface cleaners, dishwashing liquids, and green laundry concentrates.
Synergistic Preservation Systems: Enhances the broad-spectrum efficiency of standard cosmetic preservative systems, allowing formulators to reduce synthetic booster levels.
Recommended Dosage:
Personal Care Creams & Serums: 0.5% – 2.0%
Rinse-off Cleansers & Shampoos: 1.0% – 5.0%
Household & Hard Surface Cleaners: 2.0% – 10.0%
FAQ
A: Lactonic Sophorolipid features a closed-ring ester structure that grants higher surface activity, lower CMC, and superior oil-solubilizing capabilities, along with lower foaming properties. Acidic Sophorolipid has an open carboxylic chain, providing higher water solubility, better foaming, and different rheological characteristics.
A: Yes. It can partially or fully replace synthetic surfactants in formulations targeting high naturality indices. It provides comparable or superior surface tension reduction with significantly improved skin tolerance and environmental profile.
A: Store in original sealed containers in a dry, well-ventilated area between 10°C and 25°C. Protect from direct sunlight and freezing temperatures. Due to its natural biopolymeric behavior, slight viscosity changes may occur at low temperatures, which can be reversed by gentle warming and mixing without affecting performance.
