Description

Oleyl 4-Decylbenzenesulfonate is a specialized anionic surfactant belonging to the alkylbenzenesulfonate class, identified by CAS NO 56401-66-2. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, derived from its unique oleyl and decyl hydrophobic chains. It is a critical raw material for formulators in industries such as agrochemicals, lubricants, and industrial cleaning, where high-performance surface activity and stability are required.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide concentrates and adjuvant systems.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, metal cleaning formulations, and hard surface cleaners.
• Lubricant & Metalworking Fluids: Serves as an emulsifier and anti-wear additive in soluble oils and coolants.
• Textile Processing: Functions as a wetting agent and dye leveling assistant in various textile treatment baths.
• Oilfield Chemicals: Employed in drilling muds and production chemicals for its emulsifying and demulsifying capabilities.
• Paint & Coating Additives: Used as a dispersing agent for pigments and fillers in solvent-based and water-based systems.
• Leather Processing: Aids in fatliquoring and dyeing processes as an emulsifying agent.
• Research & Development: Serves as a model compound or specialty surfactant in chemical synthesis and material science.

Quality Control

Our Oleyl 4-Decylbenzenesulfonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Key parameters such as active matter content, sulfonate content, and impurity profiles are verified. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is light-sensitive and easily oxidized; prolonged exposure to air and light should be avoided to maintain product integrity. Keep away from strong oxidizing agents.
