Description

Nonanoic Acid, Sulfophenyl Ester, Sodium Salt is a specialized anionic surfactant derived from pelargonic acid. This compound is valued for its excellent wetting, emulsifying, and dispersing properties in demanding formulations. It is primarily utilized by manufacturers in the agrochemical, textile, and industrial cleaning sectors where high-performance surface activity is required.

Application

• Agrochemical Formulations: Acts as a key wetting agent and dispersant in pesticide and herbicide concentrates.
• Textile Processing: Used as a scouring and wetting agent in fabric pretreatment and dyeing processes.
• Industrial & Institutional (I&I) Cleaners: Provides effective emulsification in heavy-duty degreasers and alkaline cleaners.
• Metal Working Fluids: Serves as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants.
• Paint & Coating Additives: Functions as a pigment dispersant and grinding aid to improve color development and stability.
• Leather Processing: Employed as a wetting and penetrating agent in tanning and fatliquoring operations.

Quality Control

Our Nonanoic Acid, Sulfophenyl Ester, Sodium Salt is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance and meets specifications for critical parameters such as active matter content, pH, and moisture. Certificates of Analysis (COA) are available upon request to support your quality assurance protocols.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial opening to prevent absorption of atmospheric moisture, which may affect product performance.
