Description

Lactonic Sophorolipid is a specific, ring-closed form of the sophorolipid family, a class of glycolipid biosurfactants produced by yeast fermentation. This compound is valued for its potent surface-active properties, excellent biocompatibility, and biodegradability, making it a cornerstone for sustainable industrial formulations. It is essential for manufacturers in the personal care, household cleaning, agricultural, and biomedical sectors seeking high-performance, eco-friendly alternatives to petrochemical-based surfactants.

Application

Lactonic Sophorolipid is a versatile bio-based ingredient with applications across multiple industries:

• Personal Care & Cosmetics: As a primary emulsifier and foaming agent in shampoos, facial cleansers, and moisturizers for sensitive skin.
• Household & Industrial Cleaning: As a key surfactant in green detergents, degreasers, and hard-surface cleaners due to its excellent wetting and emulsifying power.
• Agriculture: Used in biopesticide formulations and as a soil-wetting agent to enhance the delivery and efficacy of active ingredients.
• Biomedical & Pharmaceutical: Explored for drug delivery systems, antimicrobial coatings, and wound healing applications for its self-assembling and bioactive properties.
• Enhanced Oil Recovery (EOR): Employed as an eco-friendly biosurfactant to reduce interfacial tension and mobilize trapped oil in reservoir formations.
• Food Processing: Potential use as a natural emulsifier and antimicrobial agent in certain food-grade applications.

Quality Control

Our Lactonic Sophorolipid is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance. Certificates of Analysis (COA) detailing key parameters such as lactonic content, critical micelle concentration (CMC), and microbial limits are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This material is easily oxidized; for long-term storage, consider keeping under an inert atmosphere (e.g., nitrogen) to maintain stability. Keep away from strong oxidizing agents.
