Description

Benzene, Mono-C10-13-Alkyl Derivs., Fractionation Bottoms, Heavy Ends, Sulfonated, Sodium Salts is a complex anionic surfactant derived from the sulfonation of specific alkylbenzene fractions. This product matters for its excellent wetting, emulsifying, and dispersing properties in demanding industrial formulations. It is primarily needed by manufacturers in the detergent, agrochemical, textile, and oilfield chemical industries for creating high-performance cleaning agents, pesticide emulsifiers, and drilling fluid additives.

Application

• Industrial & Institutional (I&I) Cleaners: Key surfactant in heavy-duty degreasers, floor cleaners, and metalworking fluids for its robust performance.
• Agrochemical Formulations: Acts as an effective emulsifier and wetting agent in pesticide and herbicide concentrates.
• Textile Processing: Used in scouring, dyeing, and finishing baths to improve wetting and leveling.
• Oilfield Chemicals: Employed in drilling muds and enhanced oil recovery (EOR) formulations as a surfactant.
• Paint & Coating Additives: Functions as a dispersing agent for pigments and fillers in aqueous systems.
• Leather Processing: Aids in wetting and penetration during tanning and dyeing processes.
• Construction Chemicals: Used in concrete admixtures and gypsum board production for improved flow and dispersion.

Quality Control

Our production of Benzene, Mono-C10-13-Alkyl Derivs., Fractionation Bottoms, Heavy Ends, Sulfonated, Sodium Salts adheres to stringent quality protocols to ensure batch-to-batch consistency and performance. Key parameters such as active matter content, unsulfonated oil, and inorganic salt levels are rigorously controlled. Certificates of Analysis (COA) detailing product specifications are available for every batch upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). 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.
