Description

Diammonium 1-Octadecyl 2-Sulphonatosuccinate is a high-purity, anionic surfactant belonging to the sulfosuccinate ester class. This compound is valued for its excellent emulsifying, dispersing, and wetting properties, making it a critical performance additive in demanding formulations. It is primarily sought after by manufacturers in the personal care, industrial cleaning, and agrochemical sectors who require mild yet effective surface-active agents. Consistent quality and reliable supply are paramount for its integration into stable, high-performance end products.

Application

• Personal Care & Cosmetics: Acts as a primary or secondary surfactant in mild shampoos, body washes, facial cleansers, and baby care products due to its excellent foaming and skin compatibility.
• Industrial & Institutional (I&I) Cleaning: Used in formulations for hard surface cleaners, degreasers, and vehicle wash systems for its superior wetting and emulsification of oils.
• Agrochemicals: Functions as a key component in pesticide and herbicide formulations, enhancing the spreading and adhesion of active ingredients on plant surfaces.
• Textile Processing: Employed as a wetting agent and dispersant in dyeing and finishing baths to ensure uniform color application and processing.
• Paints & Coatings: Serves as a pigment dispersant and grinding aid, improving color development and stability in water-based systems.
• Emulsion Polymerization: Utilized as an emulsifier in the production of synthetic latexes for adhesives, paper coatings, and synthetic rubbers.

Quality Control

Our Diammonium 1-Octadecyl 2-Sulphonatosuccinate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and performance. A Certificate of Analysis (COA) documenting key parameters such as assay, moisture content, and heavy metals is provided with each shipment to guarantee traceability and compliance.

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); the container must be kept tightly sealed after initial use to prevent absorption of atmospheric moisture, which can affect product performance and stability.
