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 combined with high biocompatibility and biodegradability, making it a cornerstone for sustainable industrial formulations. It is particularly sought after by manufacturers in the personal care, household cleaning, and agricultural sectors seeking high-performance, eco-friendly alternatives to petrochemical-based surfactants.

Application

• Natural & Green Cosmetic Formulations: Acts as a primary emulsifier, foaming agent, and skin-conditioning agent in creams, lotions, and cleansers.
• Household & Industrial Cleaners: Provides excellent wetting, emulsification, and detergency in "green" dishwashing liquids, laundry detergents, and hard-surface cleaners.
• Agricultural Adjuvants: Enhances the spreading, adhesion, and penetration of pesticides, herbicides, and fungicides on plant surfaces.
• Enhanced Oil Recovery (EOR): Used in microbial or chemical EOR processes to reduce interfacial tension and mobilize trapped crude oil.
• Bioremediation: Aids in the dispersion and degradation of hydrophobic environmental contaminants like oil spills and polycyclic aromatic hydrocarbons (PAHs).
• Pharmaceutical & Biomedical Research: Studied for its antimicrobial, anti-inflammatory, and immunomodulatory properties in drug delivery systems and therapeutic applications.

Quality Control

Our Lactonic Sophorolipid is produced under a stringent quality management system. Each batch undergoes comprehensive analysis to ensure consistent purity, composition, and performance. We provide detailed Certificates of Analysis (COA) that include data on lactonic content, critical micelle concentration (CMC), surface tension, and microbial limits, supporting compliance with relevant standards for cosmetic and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. The product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent moisture absorption and potential microbial growth. Keep away from strong oxidizing agents.
