Navigating the complex landscape of specialty chemicals requires a thorough understanding of their properties, synthesis pathways, and reliable sourcing channels. Dioctadecyl Dimethyl Ammonium Chloride (DODMAC), a prominent cationic surfactant identified by CAS number 107-64-2, is one such versatile chemical widely used across various industries. Its unique structure and properties as a fabric softener, antistatic agent, disinfectant, emulsifier, and organic clay modifier make it highly sought after. As a leading manufacturer and supplier of DODMAC in China, we aim to provide a comprehensive overview for procurement managers, R&D scientists, and formulators looking to source this essential compound.

The chemical identity of DODMAC is rooted in its structure: it is a quaternary ammonium salt characterized by a positively charged nitrogen atom bonded to two long octadecyl (C18) alkyl chains and two methyl groups. This structure, C38H80ClN, imparts amphiphilic qualities, meaning it has both water-attracting (hydrophilic) and oil-attracting (hydrophobic) parts. This duality is fundamental to its functionality as a surfactant. The key physicochemical properties include its appearance, typically a white to slightly yellow paste or solid, with an active content usually ranging from 74% to 76%, though higher concentrations like 80% or 85% are also available from various suppliers. Its melting point can vary, often cited between 72-122°C, and it shows good stability under normal conditions but is sensitive to moisture.

The synthesis of DODMAC generally involves the quaternization reaction between distearyl amine and methyl chloride, or alternatively, the reaction of octadecyl chloride with dimethyl octadecyl amine. The precise manufacturing process can influence the purity and consistency of the final product. As a reliable manufacturer, we adhere to strict quality control measures throughout our production cycle to ensure that our DODMAC meets the required specifications for diverse applications. Understanding the synthesis route helps in appreciating the quality factors when you buy DODMAC.

When sourcing DODMAC, it is crucial to partner with a reputable manufacturer and supplier. Key considerations include the purity of the active substance, consistency in appearance and performance, packaging options (commonly 180kg or 175kg drums), and the supplier's capacity to meet demand. Factors such as lead time, sampling policies, and technical support are also vital. We pride ourselves on being a responsive supplier, offering samples for evaluation and competitive pricing for bulk purchases. For those looking to buy DODMAC, engaging with a supplier that provides clear documentation, such as Certificates of Analysis (COA) and Technical Data Sheets (TDS), is essential for quality assurance.

In summary, Dioctadecyl Dimethyl Ammonium Chloride (DODMAC) is a powerful and versatile cationic surfactant with broad industrial applicability. Understanding its chemical structure, synthesis, and key properties is vital for effective procurement and application. As a leading manufacturer and supplier based in China, we are committed to providing high-quality DODMAC backed by excellent service and a stable supply chain. We encourage all interested parties to reach out for a product quote and samples to discover the superior performance of our DODMAC and establish a reliable sourcing partnership.
