Description

Sulfonic Acids, C10-18-Alkane, Sodium Salts is a versatile anionic surfactant derived from a mixture of linear C10 to C18 alkane sulfonic acids neutralized to their sodium salts. This compound is valued for its excellent wetting, foaming, and emulsifying properties, along with high stability across a wide pH range and good hard water tolerance. It is a critical raw material for manufacturers in the detergent, personal care, textile, and industrial cleaning sectors seeking effective and biodegradable surfactant solutions.

Application

• Detergent & Cleaning Formulations: Primary surfactant in liquid dish soaps, laundry detergents, all-purpose cleaners, and industrial & institutional (I&I) cleaners.
• Personal Care Products: Used in shampoos, shower gels, bubble baths, and hand soaps for its mildness and rich lather.
• Textile Processing: Acts as a wetting agent, scouring aid, and emulsifier in textile preparation and dyeing processes.
• Emulsion Polymerization: Serves as an emulsifier and stabilizer in the production of synthetic rubbers, plastics, and polymer dispersions.
• Agricultural Formulations: Component in pesticide and herbicide formulations as a wetting and dispersing agent.
• Leather Processing: Utilized in degreasing and wetting operations during leather tanning and finishing.

Quality Control

Our Sulfonic Acids, C10-18-Alkane, Sodium Salts is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance and meets relevant industry specifications for surfactant raw materials. A comprehensive Certificate of Analysis (COA) detailing key parameters such as active matter content, unsulfonated matter, and salt content 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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may lead to caking or reduced flowability.
