Tetraethylenepentamine (TEPA) is an organic compound and is in the class of chemicals known as ethyleneamines.

It is a slightly viscous liquid and is not colorless but, like many amines, has a yellow color.

Diethylenetriamine (DETA), triethylenetetramine (TETA), piperazine, and aminoethylpiperazine are also usually present in commercial available TEPA.

[1] The reactivity and uses of TEPA are similar to those for the related ethylene amines ethylenediamine and diethylenetriamine and triethylenetetramine.

This can be on its own or reacted with tall oil fatty acid (TOFA) and its dimer to make an amidoamine.
