Laurylamine Dipropylenediamine (DPTA) is an organic compound in the class of dodecylamines. It is a colourless liquid although commercial samples can appear yellow and exhibit an amine-like odour.
DPTA is a widely applied ingredient in many products, such as in surfactants, antimicrobials, preservatives, emulsifiers, corrosion inhibitors, chilling liquids, antistatics (e.g., in hair products), and dispersing agents.
In 2022, the EU decided upon not approving DPTA as an existing active substance for use in biocidal products of product-type 8, wood preservatives, due to the unacceptable risks for human health, and not having suitable risk mitigation measures.
