Description
Dimethyl phthalate (DMP) is a phthalate ester solvent supplied under trade names including Mipax, Avolin, Fermine, and NTM. Registered under CAS 131-11-3 and EC 205-011-6, it carries no assigned E-code and is classified within the broader phthalate plasticiser and solvent family.
In plastics and polymer processing, DMP functions as a plasticiser for cellulose acetate, improving flexibility by reducing intermolecular chain rigidity. In personal care formulations, it acts as a solvent carrier for fragrance compounds and serves as a UV-absorbing agent, attenuating ultraviolet radiation to protect both the product and the substrate.
DMP is available as a liquid grade suitable for industrial formulation. It falls under REACH regulation and requires an up-to-date Safety Data Sheet for EU procurement. Packaging is typically supplied in drums or IBCs; buyers should confirm current regulatory status under REACH Annex XIV prior to sourcing.
