Description

Sodium 5-Acetyl-2-(Hexadecyloxy)Benzenesulphonate is a specialized anionic surfactant characterized by its unique molecular structure combining a hydrophilic sulphonate head group with a long hydrophobic alkyl chain and an acetyl functional group. This compound is engineered to provide excellent surface activity, emulsification, and wetting properties in demanding formulations. It is primarily utilized in the production of high-performance industrial and specialty chemical products where tailored interfacial behavior is critical.

Application

• Specialty Surfactant for Industrial Cleaners: Acts as a key wetting and emulsifying agent in heavy-duty degreasers and industrial cleaning formulations.
• Emulsion Polymerization: Serves as a stabilizer and emulsifier in the synthesis of polymers like acrylics, styrene-butadiene, and PVC.
• Textile Processing Auxiliary: Used in scouring, dyeing, and finishing baths to improve wetting, leveling, and fiber penetration.
• Enhanced Oil Recovery (EOR): Investigated as a chemical additive to alter interfacial tension and improve oil displacement in reservoir flooding.
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to enhance spreading, adhesion, and absorption on plant surfaces.
• Personal Care & Cosmetics: Functions as a mild surfactant and emulsifier in specialized rinse-off products where specific solubility profiles are required.

Storage

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