Also known as N,N-Dimethyl-1,3-diaminopropane, 3-(Dimethylamino)-1-propylamine, N,N-Dimethyl-1,3-propanediamine
Dimethylaminopropylamine (DMAPA) is a diamine used in the preparation of some surfactants, such as cocamidopropyl betaine which is an ingredient in many personal care products including soaps, shampoos, and cosmetics. BASF, a major producer, claims that DMAPA-derivatives do not sting the eyes and makes a fine-bubble foam, making it appropriate in shampoos.

==Preparation and reactions== DMAPA is commonly produced commercially via the reaction between dimethylamine and acrylonitrile (a Michael reaction) to produce dimethylaminopropionitrile. A subsequent hydrogenation step yields DMAPA: 400px DMAPA is readily converted to the mustard dimethylaminopropyl-3-chloride, a powerful alkylating agent.
