Description

Sodium-11-Acrylamido-Undecanoate is a specialized anionic surfactant monomer that combines a long hydrophobic alkyl chain with a polymerizable acrylamido group and a hydrophilic carboxylate head. This unique structure makes it a valuable building block for synthesizing high-performance polymers with tailored surface-active and rheological properties. It is primarily used by R&D chemists and formulators in the personal care, coatings, and advanced materials industries seeking to develop novel copolymers with enhanced stability, emulsification, or adhesion characteristics.

Application

• Personal Care & Cosmetics: As a key monomer for synthesizing polymeric emulsifiers and rheology modifiers in creams, lotions, and sunscreens.
• Advanced Coatings & Adhesives: Used to create waterborne acrylic copolymers with improved pigment dispersion, film formation, and substrate adhesion.
• Enhanced Oil Recovery (EOR): A potential component in synthesizing polymeric surfactants for chemical flooding to improve oil displacement efficiency.
• Textile & Leather Processing: Employed in the production of specialty polymers used as softeners, finishing agents, or dyeing auxiliaries.
• Paper & Pulp Industry: As a comonomer for retention aids, drainage aids, or strength resins to improve paper quality and manufacturing efficiency.
• Water Treatment Chemicals: Incorporated into flocculants and scale inhibitors for industrial water treatment processes.

Quality Control

Our Sodium-11-Acrylamido-Undecanoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including identification (IR, NMR), purity assay (HPLC), and control of key impurities, to ensure consistency and reliability for your R&D and production needs. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; prolonged exposure to air, moisture, or light should be avoided to maintain product integrity.
