Description

Sodium 2,5-Dihydroxy-4-(1-Methylheptadecyl)Benzenesulphonate is a specialized anionic surfactant derived from a long-chain alkyl-substituted hydroquinone sulfonate. This compound matters for its unique combination of surface-active properties, offering excellent wetting, emulsifying, and dispersing capabilities in demanding formulations. It is primarily needed by manufacturers in the agrochemical, industrial cleaning, and specialty chemical sectors where high-performance surfactants are critical.

Application

• As a key wetting and dispersing agent in agricultural formulations such as herbicides, pesticides, and fungicides.
• In the production of industrial and institutional (I&I) cleaners and degreasers for heavy-duty applications.
• As an emulsifier and stabilizer in specialty chemical processes, including polymer and resin manufacturing.
• In the formulation of textile auxiliaries for scouring, dyeing, and finishing processes.
• As a component in metalworking fluids and lubricant additives for improved surface contact.
• Potential use in oilfield chemicals for enhanced oil recovery and drilling mud formulations.
