Description

Sodium Sulfonates CAS NO 133272-42-1 are a versatile class of anionic surfactants and emulsifiers derived from sulfonic acid salts. These compounds are valued for their excellent wetting, dispersing, and detergent properties in aqueous and non-aqueous systems. They are essential raw materials for formulators in the industrial cleaning, agrochemical, lubricant, and construction chemical sectors, where stable performance and reliable quality are critical.

Application

• Industrial & Institutional (I&I) Cleaners: Key surfactant in heavy-duty degreasers, metal cleaners, and floor care formulations.
• Agrochemicals: Acts as a wetting agent, dispersant, and emulsifier in pesticide and herbicide concentrates.
• Lubricant & Fuel Additives: Used as a detergent and rust inhibitor in engine oils and industrial lubricants.
• Construction Chemicals: Functions as a plasticizer and air-entraining agent in concrete admixtures and cement grinding aids.
• Textile & Leather Processing: Employed as a wetting and leveling agent in dyeing and finishing processes.
• Oilfield Chemicals: Serves as an emulsifier and corrosion inhibitor in drilling muds and production chemicals.

Quality Control

Our Sodium Sulfonates are manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Quality is verified through parameters including active matter content, unsulfonated oil, sodium sulfate content, and pH. A Certificate of Analysis (COA) documenting these specifications is provided with every shipment.

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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent caking or degradation from atmospheric moisture.
