Description

Sodium (Z)2-(Methyl-9-Octadecenylamino)Ethanesulphonate is a high-purity, amphoteric surfactant and specialty chemical intermediate. This compound is valued for its unique combination of anionic and cationic properties, offering excellent emulsifying, dispersing, and antistatic performance. It is primarily sought by manufacturers in the personal care, textile processing, and industrial cleaning sectors for formulating high-performance products. The material is supplied with full traceability and a Certificate of Analysis to ensure batch-to-batch consistency.

Application

• Personal Care & Cosmetics: Acts as a mild surfactant and conditioning agent in shampoos, body washes, and skin cleansers.
• Textile Auxiliaries: Used as a softener, antistatic agent, and dyeing assistant for synthetic and natural fibers.
• Industrial & Institutional (I&I) Cleaning: Serves as a key component in hard surface cleaners, degreasers, and emulsion stabilizers.
• Emulsion Polymerization: Functions as an emulsifier and stabilizer in the production of acrylic, vinyl acetate, and styrene-butadiene lattices.
• Metalworking Fluids: Employed as a corrosion inhibitor and emulsifier in synthetic and semi-synthetic coolants.
• Agricultural Formulations: Used as an adjuvant to enhance the spreading and adhesion of pesticides and herbicides.

Quality Control

Our Sodium (Z)2-(Methyl-9-Octadecenylamino)Ethanesulphonate is manufactured under a strict quality management system. Every batch is analyzed to confirm identity, purity, and conformance to agreed specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment. We support our global clients with documentation for regulatory compliance, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
