Description

Benzenesulfonic Acid, Oxybishexadecyl-, Disodium Salt is a high-purity, synthetic anionic surfactant derived from benzenesulfonic acid. This compound is valued for its excellent emulsifying, dispersing, and wetting properties in demanding industrial formulations. It serves as a critical performance additive for manufacturers in the personal care, agrochemical, and specialty chemical industries seeking reliable and consistent raw materials.

Application

• Primary Emulsifier in agricultural pesticide and herbicide formulations.
• Key Dispersing Agent for pigments and fillers in industrial coatings and inks.
• Stabilizing Surfactant in the production of emulsion polymers (e.g., acrylics, styrene-butadiene).
• Wetting and Leveling Agent in textile processing and dyeing applications.
• Emulsion Stabilizer in select personal care products, such as creams and lotions.
• Additive for industrial and institutional (I&I) cleaning formulations.

Quality Control

Our Benzenesulfonic Acid, Oxybishexadecyl-, Disodium Salt is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles 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 a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
