Description

Didodecyldimethylammonium is a quaternary ammonium compound (QAC) characterized by its two long-chain dodecyl groups. This structure is critical for its function as a highly effective cationic surfactant and phase-transfer catalyst, providing superior surface activity and chemical stability. It is essential for manufacturers and formulators in industries requiring robust antimicrobial action, material modification, or specialized synthesis. The compound is supplied to meet the stringent quality and consistency demands of global industrial and research applications.

Application

• As a key cationic surfactant and emulsifier in industrial cleaning and disinfectant formulations.
• Primary active ingredient in algicides, bactericides, and fungicides for water treatment and material preservation.
• As a phase-transfer catalyst (PTC) in organic synthesis, facilitating reactions between immiscible reactants.
• Fabric softener and antistatic agent component in textile and laundry care products.
• Modifier for clay and mineral surfaces (e.g., bentonite) to create organoclays for nanocomposites and drilling fluids.
• Biocide in paints, coatings, and polymer emulsions to prevent microbial degradation.
• Raw material for the synthesis of other quaternary ammonium compounds and specialty chemicals.
• Conditioning agent in personal care and cosmetic products (subject to regional regulatory approval).

Quality Control

Our Didodecyldimethylammonium products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Key parameters such as assay/purity, identity, and residual solvents are verified using advanced analytical techniques including HPLC, GC, and NMR. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request. We adhere to a cGMP compliant quality management system to support applications in regulated markets.

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). Keep away from strong oxidizing agents and incompatible materials. For long-term storage, consider an inert atmosphere to maintain optimal quality.
