Description

p-(Decanoyloxy)Benzenesulfonic Acid Sodium Salt is a specialized anionic surfactant and intermediate with a unique molecular architecture combining a sulfonate head group and a fatty acid ester chain. This structure is critical for its function as a versatile emulsifier, wetting agent, and solubilizer in demanding formulations. It is essential for industrial chemists and formulators in sectors requiring high-performance surface-active properties and chemical synthesis.

Application

• Emulsifier and Stabilizer in polymerization processes (e.g., for styrene, acrylates) and in the production of specialty polymers and resins.
• Wetting and Dispersing Agent in agrochemical formulations for pesticides and herbicides to improve coverage and efficacy.
• Intermediate in Organic Synthesis for the production of more complex surfactants, dyes, and pharmaceutical agents.
• Detergent and Cleaning Agent Component in industrial and institutional cleaning products requiring high grease-cutting power.
• Textile Processing Aid used in dyeing and finishing operations to enhance dye leveling and fiber penetration.
• Additive in Lubricants and Metalworking Fluids to improve emulsion stability and surface wetting.
