Introduction

Rhamnolipid is a glycolipid biosurfactant produced through microbial fermentation, primarily by Pseudomonas species. As one of the most studied and widely applied biosurfactants globally, rhamnolipid is celebrated for its outstanding surface activity, natural origin, and excellent environmental compatibility. Structurally, it is an amphiphilic molecule consisting of a hydrophilic head group (composed of one or two rhamnose sugar units) and a hydrophobic tail (composed of one or two fatty acid chains). This dual affinity enables rhamnolipids to effectively reduce surface and interfacial tension, facilitating the mixing of immiscible substances such as oil and water.

As a professional supplier of surfactants, our company offers high-purity, high-performance rhamnolipid biosurfactants tailored to meet the demands of environmentally conscious industries.

Characteristics

• Rhamnolipid is composed of rhamnose sugar moieties and β-hydroxy fatty acid chains, which grant it strong amphiphilic properties. This molecular structure enables rhamnolipid to reduce surface and interfacial tension between immiscible phases such as oil and water, stabilizing emulsions and enhancing solubility.
• In addition to its outstanding surfactant performance, rhamnolipid exhibits beneficial bioactivities including antimicrobial, antiviral, moisturizing, and wound-healing effects.

Basic Parameters

Key physicochemical attributes include:

• Surface tension: 25-40 mN/m

Applications

Due to its multifunctionality and biocompatibility, rhamnolipid is recognized as one of the most studied and versatile biosurfactants worldwide, including:

• Personal Care & Cosmetics: Used in formulations for skincare, wound healing creams, and moisturizing products due to its gentle and bioactive nature.
• Household & Industrial Cleaning: It offers excellent emulsification, detergency, foaming, and dispersion, suitable for green cleaning agents and degreasers.
• Agriculture & Agrochemicals: It acts as a green adjuvant in pesticide formulations, soil remediation agents, and fertilizer enhancers.
• Oil & Gas Industry: It enhances oil recovery (EOR), cleans oil pipelines, and is used in drilling fluid treatments.
• Environmental Remediation: Effective in bioremediation of polluted soils and wastewater due to its surfactant and microbial-enhancing properties.
• Formulation Synergy: Compatible with a wide range of other surfactants for performance enhancement.

Competitive Advantages

• Eco-Friendly: 100% biodegradable, non-toxic (OECD-certified).
• Synergistic: Compatible with other surfactants (e.g., SLES, betaines) for enhanced performance.
• Customizable: Available in varying purities (crude to >90%) and formulations.
