DTPMPA, or diethylenetriamine penta (methylene phosphonic acid), is a chemical compound used in various industrial applications. It has chelating and anti-corrosion properties, making it useful in water treatment, detergents, and textile dyeing. It binds to metal ions, preventing them from reacting with other substances and causing problems.


DTPMPA’s chelating properties also come in handy in the textile industry, where it acts as a stabilizer for peroxides used in bleaching processes. Additionally, it functions as a dispersant, keeping dyes and pigments suspended in solution and preventing them from clumping. In the agricultural sector, It serves as a chelating agent for micronutrients, ensuring their efficient delivery to plants. It also finds use in the papermaking industry as a dispersant for fillers and coatings, and in the personal care industry as a stabilizer for ingredients like hydrogen peroxide.


UniVOOK offers DTPMPA in various grades and packaging options to meet the specific needs of our customers. We also provide technical support and guidance to ensure optimal product performance.
