Dimethyl lauryl amine

Buyers must prioritize purity levels, typically requiring ≥98% or ≥99% for high-end chemical synthesis. Key parameters include the Amine Value (typically 255-265 mg KOH/g), Color (APHA ≤30), and Water Content (≤0.2%). Ensure the C12 content is strictly monitored if the application requires specific chain length distribution, as variations can affect the performance of downstream surfactants like betaines or quaternary ammonium salts.

As a hazardous chemical, it must have a comprehensive Material Safety Data Sheet (MSDS/SDS) compliant with GHS standards. For international trade, verify the CAS Number (112-18-5) and ensure the supplier provides a Certificate of Analysis (COA) for every batch. If the end product is for personal care, check for REACH (EU) registration or TSCA (US) compliance to ensure the substance is permitted in the target market.

Dimethyl Lauryl Amine is a critical intermediate used primarily in the production of cationic and amphoteric surfactants. It is essential for manufacturing quaternary ammonium salts (disinfectants/sanitizers), amine oxides (foam stabilizers in detergents), and betaines (mild surfactants for shampoos). Its functional value lies in its antistatic properties, corrosion inhibition, and emulsification capabilities.

Due to its corrosive nature and sensitivity to oxidation, DLA should be stored in galvanized iron drums, plastic drums (IBC tanks), or stainless steel tanks. Ensure the supplier uses nitrogen blanketing during packaging to prevent contact with air, which can lead to discoloration and degradation. Storage facilities must be cool, dry, and well-ventilated, away from acidic materials and strong oxidants.

DLA is classified under UN 2735 (Amines, liquid, corrosive, n.o.s.), belonging to Hazard Class 8. Shipping requires IMDG-compliant packaging and specialized dangerous goods (DG) forwarding services. Buyers must ensure the supplier has a Dangerous Goods Transport License and provides the Dangerous Goods Declaration to avoid customs seizures or heavy fines at the port of entry.

Utilize secure payment methods and prioritize suppliers on Made-in-China.com who have undergone Audited Supplier verifications. It is highly recommended to use third-party inspection services (like SGS or Intertek) to perform pre-shipment sampling and testing to ensure the chemical composition matches the agreed-upon COA before the final balance is paid.

Prices for fatty amines are heavily influenced by raw material costs (Lauryl Alcohol) and petrochemical fluctuations. Negotiate based on volume-based pricing tiers (e.g., 20ft FCL vs. LCL) and consider long-term supply contracts with price adjustment formulas linked to market indices to stabilize costs. Always request FOB or CIF quotes to clearly delineate where the risk of loss transfers.

The most common pitfall is the misclassification of H.S. Codes, which can lead to incorrect duty payments or legal issues. Ensure the correct code (typically 2921.19) is used. Additionally, verify if the target country has Anti-Dumping Duties (ADD) on Chinese chemical exports or specific Environmental Protection Agency (EPA) import notifications required before the cargo arrives.
