Dimethyl phthalate (DMP) is a clear, colorless to light yellow, oily liquid with a slight sweet odor. It is slightly soluble in water, soluble in organic solvents (e.g. methanol, diethyl ether). Stable under ordinary conditions. Incompatible with strong oxidizing agents, strong acids or bases, nitrates. Sensitive to prolonged exposure to light.





Dimethyl phthalate is an antiparasitic drug (ectoparasiticide),  used in the treatment of ectoparasitic infestations such as nematodes, cestodes, trematodes, infectious protozoa, and amoebas. It can be applied for treatment of rickettsial infections, as a miticidal agent.



DMP has an application as insect (for fleas, chiggers and flies on horses and cows) and mosquito repellents in some topical formulations such as creams, aerosols and lotions, and in pesticides.

Dimethyl phthalate plasticizers polyvinyl acetate and rubber. It is used as a plasticizer in cellulose ester plastics, such as photographic films and sheets, blister packaging and tape applications.

DMP imparts flexibility and impacts strength of plastics. It makes plastics more flexible in products such as toothbrushes, automobile parts, tool handles, toys and food packaging. It is applied as an additive in polysulfide rubber to reduce shear strength.



Dissolves many natural resins, glyceryl-phthalate resin and may be used with coumarone resins.
