Description

Benzenesulfonic Acid, C20-48-Alkyl Derivs., Sodium Salts is a high-molecular-weight anionic surfactant derived from the sulfonation of linear alkylbenzenes with a C20-48 carbon chain. This compound is valued for its powerful surface-active properties, excellent emulsifying power, and stability across a wide pH range. It is a critical raw material for formulators in industries such as industrial cleaning, textile processing, and emulsion polymerization, where robust detergency and wetting are required.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a primary surfactant in heavy-duty alkaline cleaners, degreasers, and floor care formulations.
• Textile Auxiliaries: Used as a wetting agent, scouring agent, and emulsifier in textile pretreatment and dyeing processes.
• Emulsion Polymerization: Serves as an effective emulsifier and stabilizer in the production of synthetic rubbers, plastics, and latex paints.
• Metal Working Fluids: Functions as an emulsifier and corrosion inhibitor in soluble oils and semi-synthetic metalworking fluids.
• Agricultural Formulations: Employed as a dispersant and wetting agent in pesticide and herbicide concentrates.
• Oilfield Chemicals: Used in drilling muds and oil recovery formulations for its emulsifying and dispersing properties.
