Description

Citowett CAS NO 39342-50-2 is a high-performance non-ionic surfactant and wetting agent, scientifically known as sodium dioctyl sulfosuccinate. Its core value proposition lies in its exceptional ability to dramatically lower surface tension, enabling superior wetting, spreading, and penetration in aqueous systems. This makes it an indispensable processing aid for industries requiring efficient dispersion and contact. Key sectors that rely on this compound include agrochemical formulation, industrial cleaning, textile processing, and polymer emulsion production.

Application

• Agrochemical Formulations: Acts as a key wetting agent and dispersant in wettable powders (WP), suspension concentrates (SC), and other pesticide formulations to ensure uniform coverage and efficacy on plant surfaces.
• Industrial & Institutional (I&I) Cleaning: Used in heavy-duty degreasers, metal cleaners, and floor care products for its powerful wetting and emulsifying properties on oily soils.
• Textile Processing: Serves as a wetting agent and penetrant in dyeing, bleaching, and finishing baths to promote even dye uptake and chemical processing.
• Polymer & Emulsion Production: Functions as an emulsifier in the polymerization of synthetic rubbers (e.g., ABS, SBR) and in the production of acrylic and vinyl acetate emulsions.
• Paper & Pulp Industry: Employed as a de-inking agent and dispersant to aid in the removal of inks and coatings during paper recycling processes.
• Oilfield Chemicals: Utilized in drilling muds and completion fluids as an emulsifier and wetting agent to improve fluid performance.
• Coatings & Inks: Enhances pigment wetting and dispersion in water-based paints, coatings, and printing inks, improving color development and stability.
• Personal Care (Industrial Grade): Found in select industrial-grade cosmetic and toiletry formulations as a foaming agent and surfactant, subject to appropriate purity specifications.

Quality Control

Our Citowett is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for active content, moisture, and impurity profiles. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, pH, and residue on ignition. Our production adheres to cGMP principles where applicable, ensuring consistency and traceability for demanding industrial and pharmaceutical intermediary applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled 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 can affect performance. Keep away from strong oxidizing agents.
