dimethyl phthalate an overview plasticizer chemical,approximately 90% of phthalates, particularly the higher-molecular-weight compounds, are used as plasticizers (dehp, dinp, and didp). 3 for example, pvc is a rigid polymer unless a plasticizer is added to make it flexible. the lower-molecular-weight phthalates.

as suggested in reaction (6.1.1), the process may take place with the participation of an inert molecule m.the reaction has been studied in solution as well as in the gas phase [1].the decomposition in solution (dimethyl phthalate solvent) takes place very rapidly, with a reaction rate (first order) of about 3 × 10 − 5 s − 1 at 112 c and 2 × 10 − 4 s − 1 at 153 c.
a review of common non-ortho-phthalate plasticizers for use in food,plasticizers reviewed in this paper were selected from non-ortho-phthalate plasticizers reported in a study by fda staff (carlos et al. 2018), from the relevant information in the list of available datasets from the u.s. food and drug administration (fda, 2021a

- What is dimethyl phthalate (DMP)?
- Dimethyl phthalate (DMP) is a member of the group of esters of phthalic acid commonly known as phthalates, used ubiquitously as solvents and plasticisers worldwide. The Phthalate Esters Panel of the American Chemistry Council (2006 revised) derived three categories of phthalates based on use, physicochemical and toxicological properties.
- Is DMP a mixed phthalate plasticiser?
- The leaching (migration) rates of DMP as a component of a mixed phthalate plasticiser (DINP+DMP) under mouthing conditions are based on those measured in human volunteers for DINP—a common primary plasticiser found in toys.
- Which phthalates are used as plasticizers?
- Approximately 90% of phthalates, particularly the higher-molecular-weight compounds, are used as plasticizers (DEHP, DiNP, and DIDP). 3 For example, PVC is a rigid polymer unless a plasticizer is added to make it flexible.
- When was dimethyl phthalate declared a Priority Existing Chemical (PEC)?
- Dimethyl phthalate (DMP) (CAS No. 131-11-3) was declared as a priority existing chemical (PEC) for public health risk assessment under the Industrial Chemicals (Notification and Assessment) Act 1989 (the Act) on 7 March 2006. The decision for declaration was based on:
- Which phthalate is most commonly used in industry?
- The most commonly used in industry include dibutyl phthalate (DBP), di-2-Ethyl Hexyl Phthalate (DEHP), and dimethyl phthalate (DMP), which are readily freed into the environment (Buoso et al., 2020).
- What is the NOAEL for DMP based on LMW phthalate?
- Therefore, for the systemic organ effects, by applying the LMW phthalate category approach and read-across from DEP data, a no observed adverse effect level (NOAEL) of 150 mg/kg bw/d is derived for DMP based on increased liver weight at 750 mg/kg bw/d (Brown et al. 1978).
