Introduction

Sodium surfactin is a potent bio-surfactant derived from Bacillus subtilis. Originally discovered in 1968, sodium surfactin is produced via natural fermentation processes, making it a sustainable and environmentally friendly alternative to conventional chemically synthesized surfactants. This compound is celebrated for its ultra-low critical micelle concentration (CMC), superior emulsification properties, high thermal stability, and excellent biodegradability.

Characteristics

Sodium surfactin is distinguished by several key characteristics essential for its applications:

• Molecular Structure: Sodium surfactin boasts a unique molecular structure comprising a hydrophilic cyclic peptide moiety constructed from seven amino acids and a hydrophobic hydrocarbon chain. This distinct amphiphilic configuration is responsible for its remarkable surface activity and low usage rates.
• Critical Micelle Concentration (CMC): Sodium surfactin exhibits an exceptionally low CMC of 0.003%, which is 1/3000th of lecithin and 1/300th of synthetic surfactants.
• Emulsification Efficiency: The compound's ability to form D-phase emulsions, a bi-continuous phase incorporating both oil and water, at a mere 0.1% concentration to emulsify 10% oil, is noteworthy.
• Low Skin Irritation: In skin irritation tests, no observable irritation was noted at concentrations up to 2.5%.
• Biodegradability: The compound is easily biodegradable, decomposing within a week in natural water bodies such as seas and rivers.

Applications

Sodium surfactin finds applications in the following aspects due to its versatile properties:

• Facial Cleansers: Sodium surfactin is extensively used in facial cleansing products, including lash washes, facial washes, and exfoliating cleansers. Its mild yet effective surfactant properties ensure thorough cleansing without irritating sensitive facial skin.
• Body Washes: In body care, sodium surfactin serves as an excellent ingredient for hand and body washes. Its ability to emulsify oils efficiently ensures that the skin is left clean and refreshed without any greasy residue.
• Shampoos: The surfactant is suitable for shampoos designed for dry to normal hair types and sensitive scalps. Its gentle cleansing action removes dirt and excess oil while preserving the scalp's natural moisture balance.
• Make-Up Removers: Due to its exceptional emulsification capabilities, sodium surfactin is ideal for make-up removers. It effectively dissolves and removes make-up, including waterproof formulations, without leaving the skin feeling dry or irritated.
• Oil Cleansers: Sodium surfactin's ability to create stable emulsions makes it a perfect candidate for oil cleansers. These products leverage its emulsifying power to effectively remove oils, impurities, and pollutants from the skin.

Storage

• Storage Conditions: Stored in a cool, dry place away from direct sunlight and heat sources to maintain the compound's integrity and efficacy.
