Description

n-[2-[(Sodiosulfo)Oxy]Ethyl]Octadecanamide is a high-purity, synthetic anionic surfactant derived from stearic acid. This compound is valued for its excellent emulsifying, dispersing, and wetting properties in aqueous systems. It is primarily utilized in the formulation of industrial and institutional cleaning products, textile processing aids, and personal care applications where a mild, effective surfactant is required.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a key emulsifier and wetting agent in heavy-duty degreasers, floor cleaners, and spray-and-wipe formulations.
• Textile Processing: Used as a scouring agent, dye leveling agent, and softener component in fabric treatment baths.
• Personal Care: Serves as a mild primary or secondary surfactant in shampoos, body washes, and liquid soaps.
• Emulsion Polymerization: Functions as an effective emulsifier and stabilizer in the production of acrylic, styrene-butadiene, and vinyl acetate polymers.
• Agricultural Formulations: Employed as a dispersant and wetting agent in pesticide and herbicide concentrates to improve spray coverage and efficacy.
• Leather Processing: Aids in the wetting and penetration of fats and dyes during the tanning and finishing stages.

Quality Control

Our production of n-[2-[(Sodiosulfo)Oxy]Ethyl]Octadecanamide adheres to stringent quality management protocols. Every batch is analyzed to ensure consistent performance and meets specifications for critical parameters such as active matter content, moisture, and ionic balance. A comprehensive Certificate of Analysis (COA) documenting purity, identity, and physical characteristics is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent caking or degradation due to moisture absorption. Keep away from strong oxidizing agents.
