Description
Dimethylaminopropylamine (DMAPA, CAS 109-55-7) is a bifunctional aliphatic amine carrying both a primary and a tertiary amino group within a three-carbon chain. It is also referenced as 3-dimethylaminopropylamine or gamma-dimethylaminopropylamine. No E-code is assigned; it is identified under EC 203-680-9.
In personal care formulations, DMAPA reacts with fatty acids or carbomers to form conditioning agents and rheology modifiers, adjusting charge and texture in rinse-off products. In pharmaceutical and food-grade applications, its primary amine acts as a buffering site, neutralising acidic intermediates and stabilising pH-sensitive active compounds during processing.
DMAPA is supplied as a technical or high-purity liquid grade, with compliance documentation available for REACH registration under HS code 29212900. Procurement teams should request certificates of analysis aligned with relevant pharmacopoeial or food-grade standards. Standard packaging includes IBC containers and drums.
