Beauty & Personal Care: Betaine Synthesis

Synthesis of amphoteric surfactants, specifically Betaines. By reacting DMAPA with fatty acids, manufacturers produce surfactants that provide excellent foam stability and are exceptionally gentle on the skin and eyes

Specialty Chemicals: Epoxy Curing & PU Catalysts

Hardener and accelerator in epoxy resin systems. Tertiary amine group provides rapid catalytic activity, while the primary amine integrates into the polymer matrix. Catalyst in the production of Polyurethane (PU) foams, particularly for automotive interiors

Water Treatment & Paper: Cationic Polymers

Specialized cationic monomers used in water treatment as flocculants and in paper manufacturing as retention aids. These polymers effectively neutralize negatively charged particles, clarifying water and improving paper strength

Storage Stability

Highly flammable and sensitive to moisture and CO2. Reacts with air to form carbamates.

Storage Section

Store in a cool, dry, well-ventilated area. Use stainless steel, carbon steel, or HDPE tanks. Must be kept under a Dry Nitrogen Blanket to prevent oxidation and moisture absorption

Shipping

Regulated as Class 8 (Corrosive) and Class 3 (Flammable). Available in 165kg steel drums, 800kg IBCs, and ISO tanks.
