N,N-Dimethyldodecylamine (CAS No. 112-18-5)

Chemical Structure

Product Profile and Core Specifications:

In the high-volume industrial synthesis of personal care products, detergents, and household cleaners, the mildness and performance of final surfactants depend on the purity of their starting building blocks. N,N-Dimethyldodecylamine (CAS No. 112-18-5), commercially known as Dimethyl Lauryl Amine (DMA 12), is a foundational linear C12 tertiary alkylamine. It serves as an irreplaceable raw material for synthesizing advanced, ultra-mild amphoteric and cationic surfactants—such as alkyl dimethyl amine oxides (Lauramine Oxide) and betaines—which act as primary foam boosters in sulfate-free shampoos and body washes.

As a large-scale, fully integrated oleochemical source factory, we manufacture and supply high-purity Dimethyl Lauryl Amine (DMA 12) worldwide. Our product features a strictly controlled carbon-chain distribution, minimal primary and secondary amine impurities, and an exceptionally low color index on the APHA scale. This ensures that downstream chemical processors can produce crystal-clear cosmetic ingredients completely free of off-odors.

Our commercial-grade N,N-Dimethyldodecylamine is a clear, colorless to slightly yellowish liquid with a faint, characteristic fatty amine odor. The molecule is virtually insoluble in water but highly miscible with most organic solvents, serving as a highly stable reactive block.

- Chemical Formula: C₁₄H₃₁N
- CAS Number: 112-18-5 (EC Number: 203-943-8)
- Tertiary Amine Content (Assay): ≥ 98.0%
- Primary & Secondary Amine Impurities: ≤ 0.3% (Critical for minimizing unwanted secondary reactions during ethoxylation or quaternization)
- Moisture Content: ≤ 0.2%
- Color Index (APHA): ≤ 30 (Guarantees the synthesis of brilliant white or transparent surfactants without needing secondary bleaching agents)

Industrial Applications:

Advanced Extraction & Crystallization Technology:

A major technical defect encountered when sourcing DMA 12 from uncertified tier-2 traders is an unstable or broad carbon-chain distribution (high percentages of C14/C16 fractions). This structural variance shifts the freezing points and HLB values of the resulting surfactants. Our chemical plant eliminates this risk through advanced catalytic amination technology:

Reductive Amination: Natural, plant-derived lauryl alcohol (C12) undergoes a direct gas-liquid reaction with dimethylamine over specialized fixed-bed copper or nickel catalysts.
High-Vacuum Fractional Distillation: The crude amine stream enters multi-stage, high-vacuum fractionation columns where the C12 fraction is isolated with a precision threshold of ≥ 98%, stripping away volatile light ends and heavy pitches.
Nitrogen Blanketing Strategy: The finished tertiary amine is packaged and sealed exclusively under a continuous ultra-pure nitrogen cushion, preventing contact with atmospheric carbon dioxide and the formation of unreacted amine salts.

Production Capacity and Robust Inventory Program:

We actively mitigate raw material supply shocks for our global B2B partners through extensive scale and logistics infrastructure:

Annual Plant Output: Our dedicated tertiary fatty amine production lines yield up to 2,000 Metric Tons of N,N-Dimethyldodecylamine annually.
Terminal Storage Capacity: Our plant integrates a specialized liquid chemical bulk terminal with automated climate control, maintaining a minimum rolling buffer stock of 60 to 100 tons for prompt dispatch.
Custom Carbon Blends: Upon request from large-scale surfactant manufacturers, we can adjust column parameters to produce custom-blended tertiary amines (e.g., Lauryl-Myristyl Dimethyl Amine C12-C14) to meet specific foaming profile requirements.

Competitive Factory Advantages:

Establishing a direct supply contract with our manufacturing plant provides deep structural and technical advantages to your procurement framework:

High Reaction Conversion Rates: Low residual levels of unreacted free fatty alcohols ensure perfect stoichiometric accuracy during oxidation (for amine oxide production) and quaternization reactions.
Oxidative and Color Stability: Exceptional refinement and removal of trace process metals ensure that the cosmetic ingredients you synthesize will not undergo yellowing or discoloration during extended warehousing.
Comprehensive Regulatory Compliance: Our entire plant operates under ISO 9001:2015 certification. We provide batch-specific Certificates of Analysis (COA), Technical Data Sheets (TDS), and updated Safety Data Sheets (SDS) matching GHS standards for seamless cross-border maritime shipping.

Packaging and shipping

Because N,N-Dimethyldodecylamine is a corrosive and environmentally hazardous substance (UN Class 8, PG III / Class 9), it demands strict adherence to Dangerous Goods (DG) maritime and overland shipping protocols:

Industrial Packaging Formats:
- Heavy-duty steel drums featuring a specialized internal anti-corrosion liner, holding 160 kg / 170 kg net weight.
- Intermediate Bulk Containers (IBC Totes / Eurocubes) holding 800 kg net weight.
- Bulk shipments via certified ISO Tanks for contract-level industrial accounts.
Global Logistics Reach: We operate regular cross-border multi-modal freight routes. We support flexible Incoterms including FOB, FCA, CFR, and CIF, and can provide door-to-door DDP logistical packages with full chemical import documentation clearance.
