Description

Potassium 3-Sulphonatopropyl Undec-10-Enoate is a specialized anionic surfactant featuring a terminal double bond and a sulfonate group. This unique molecular structure provides excellent water solubility, surface activity, and the capability for further chemical modification, making it a valuable intermediate for advanced formulations. It is primarily sought after by manufacturers in the polymer, textile, and personal care industries for creating high-performance, functionalized materials.

Application

• Polymer Industry: Key monomer for the synthesis of sulfonated polymers, imparting hydrophilicity and ion-exchange properties to materials for membranes, hydrogels, and coatings.
• Textile Auxiliaries: Used as a wetting agent, dispersant, or emulsifier in dyeing and finishing processes, particularly for synthetic fibers.
• Personal Care & Cosmetics: Serves as a mild surfactant or emulsifying agent in rinse-off products like shampoos and body washes, offering good skin compatibility.
• Emulsion Polymerization: Acts as a reactive surfactant or stabilizer in the production of latexes and acrylic dispersions, incorporating into the polymer backbone.
• Specialty Chemicals: Intermediate for the synthesis of other sulfonate-containing surfactants or functional additives with specific performance characteristics.
• Adhesives & Sealants: Can be utilized to modify the surface properties and improve the stability of aqueous adhesive formulations.

Quality Control

Our Potassium 3-Sulphonatopropyl Undec-10-Enoate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing key parameters such as assay, moisture content, and impurity profile is provided with every shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture which may affect product quality.
