Figure: Structural formula of 3-Dimethylaminopropylamine (DMAPA), also known as N,N-dimethyl-1,3-propanediamine (CAS 109-55-7). DMAPA is an aliphatic diamine (C₅H₁₄N₂) featuring both a tertiary dimethylamino group and a primary amino group. It is a clear, colorless, weakly basic liquid with a pungent amine odor. Highly soluble in water, alcohols and other polar solvents, DMAPA’s dual amine functionality drives its versatile chemical reactivity.

• Surfactants and Personal Care: DMAPA is a key intermediate for surfactant production. For example, it reacts with coconut/palm fatty acids to form amphoteric betaines (e.g. cocamidopropyl betaine) used in soaps, shampoos and detergents. These surfactants enhance foaming and cleaning while providing conditioning and mildness. DMAPA’s versatility also makes it useful in cationic surfactants (quaternary ammonium salts) for fabric softeners and shampoo additives.

• Epoxy and Polymer Curing: DMAPA serves as a catalyst or curing agent in polyurethanes and epoxy resins. It is commonly used as an epoxy hardener or polyurethane catalyst, promoting rapid crosslinking for high-strength coatings, adhesives and foams. Polyetheramines derived from DMAPA provide flexibility and chemical resistance in polyurethanes, and DMAPA itself reacts with epoxides to form 3D polymer networks in thermosets.

• Coatings and Adhesives: In the coatings and adhesives sectors, DMAPA improves resin curing and adhesion. It functions as a curing agent for epoxy and phenolic resins, yielding coatings with high strength and corrosion resistance. It also acts as a dispersant and stabilizer for pigments in paints and inks, enhancing gloss and uniformity. As an additive in adhesives, DMAPA increases bond durability for both industrial and consumer applications.

• Gas Purification and Water Treatment: The two amine groups in DMAPA make it effective for acid gas removal. It reacts readily with acid gases like CO₂ and H₂S, so DMAPA-based solutions are used in gas purification units to scrub harmful emissions. In water treatment, DMAPA is converted into cationic polymers (via reaction with epichlorohydrin) that serve as flocculants and coagulants, improving treatment efficiency.

• Pharmaceuticals and Agrochemicals: DMAPA is a valuable chemical building block for fine chemicals, drugs and agrochemicals. Its multifunctional nature allows it to participate in a variety of organic syntheses. It is used as a raw material for local anesthetics, antibiotics and other pharmaceuticals, as well as intermediates for pesticides and plant-protection agents. DMAPA-derived intermediates help formulate crop protection products and specialty agrochemicals.

DMAPA is prized in “green" cleaning and personal-care products. Because DMAPA easily converts into amphoteric betaines, it enables biodegradable surfactants with excellent mildness. For instance, cocamidopropyl betaine (from DMAPA) is highly biodegradable and imparts gentle cleansing action. DMAPA-based betaines are widely used because they do not sting the eyes and produce fine, stable foam. In practice, DMAPA is the reason many shampoos and liquid soaps feel non-irritating on skin and eyes. This makes DMAPA especially important for formulating low-sensitization, eco-friendly detergents and personal-care items.

Global demand for DMAPA is rising steadily, driven mainly by personal care and cleaning markets. Major growth comes from high-purity (≥99%) DMAPA, which already accounts for a significant portion of sales. Buyers in cosmetics, pharmaceutical and water-treatment sectors insist on ultra-pure DMAPA to meet strict safety and regulatory standards. Regulatory pressures further elevate the demand for ≥99% purity grades. Meanwhile, stability of supply is critical: leading producers in China and India are expanding capacity to meet this demand. For overseas purchasers searching “DMAPA supplier China" or “3-Dimethylaminopropylamine manufacturer," reliability and consistent quality are top priorities.

China dominates global DMAPA production. Asia–Pacific (led by China and India) accounts for a large share of world DMAPA demand. Major Chinese chemical hubs integrate raw materials to produce DMAPA at scale. This regional advantage brings cost efficiencies and enables compliance with international standards and streamlined export logistics via major ports.
