What is 3-Dimethylaminopropylamine?

3-Dimethylaminopropylamine (DMAPA) is a diamine used in the preparation of certain surfactants, such as coconut amidopropyl betaine, which is an ingredient of many personal care products, including soap, shampoo and cosmetics. BASF, the main manufacturer, claims that DMAPA derivatives do not hurt eyes and will produce fine foam, making them suitable for shampoo.

For example, diamines are necessary structural devices in the process of synthesizing polyamides and also in other polycondensation responses. N,N-Dimethyl-1,3-diaminopropane (DMAPA) is an important intermediate for industrial preparation such as lubricants, in addition, DMAPA is used as a raw material for the preparation of coagulants, which itself should have Corrosion resistance.
