High Molecular Weight Phthalate Plasticizers: Myths & Facts
High molecular weight (HMW) phthalates are some of the most widely used general purpose plasticizers today. This is not by accident or a result of a lack of alternatives; rather, their broad decades-long history of use is a testament to their strong performance, durability, versatility, cost-effectiveness and excellent safety record.
Phthalates in Food Packaging and Food Contact Applications
The FDA revoked authorizations for the food contact use of 23 phthalates and two other substances used as plasticizers, adhesives, defoaming agents, lubricants, resins, and slimicides.

with the lower molecular weight phthalate monoesters, such as MEP, because the metabolism of the higher molecular weight phthalates is more complex and results in more metabolites, thus decreasing the relative amounts of their monoester metabolite. On the other hand, hydrolytic monoesters of high molecular weight phthalates (for
Ortho-phthalates - Plasticisers - Information Center
High molecular weight ortho-phthalates High molecular weight (HMW) or high ortho-phthalates include those with 7-13 Carbon atoms in their chemical backbone, which gives them increased permanency and durability. The most common types of high ortho-phthalates include DINP, DIDP, DPHP, DIUP, and DTDP.
- Which phthalate is used as plasticizer?
- High-molecular weight phthalates, such as di (2-ethylhexyl) phthalate (DEHP) and diisononyl phthalate (DiNP), are used as plasticizers to impart flexibility to polyvinyl chloride (PVC) materials used to make food packaging, flooring, and medical equipment (tubing, blood bags).
- What are high-molecular-weight phthalates used for?
- High-molecular-weight phthalates—including DEHP, DINP, and DOP—are used in plastic tubing, food packaging and processing materials, containers, vinyl toys, vinyl floor coverings, and building products (ATSDR 1997, 2002; ECB 2003; Kueseng et al. 2007).
- Why do phthalates and alternative plasticizers have different mass-transfer characteristics?
- As SVOCs have significant partition capacities on gas-solid interfaces, phthalates and alternative plasticizers exhibit mass-transfer characteristics that differ from other pollutants, such as volatile organic compounds and nanoparticles, which have smaller and larger molecular weights, respectively.
- Are alternative plasticizers more dangerous than phthalates?
- In contrast to phthalates, alternative plasticizers were reported less frequently and had lower dust-phase concentrations , . DINCH and DEHT were the top two alternative plasticizers of concern due to their high detection rates (see the dust sheet of Supplementary Material B for details).
- Are plastic manufacturers and suppliers exposed to phthalates?
- Plastic manufacturers and suppliers are required to understand plastic regulations to meet national and international standards. Till now, information related to occupational exposure to phthalates remains limited. Further research is required to assess the risk of occupational exposure to phthalates.
- How many phthalates are there in indoor plasticizers?
- The global occurrence and concentrations of indoor plasticizers were reviewed. Widely reported 10 phthalates and 14 alternative plasticizers were investigated. Indoor plasticizers in 4 phases were discussed across multiple dimensions. Mass transfer and partition of plasticizer were analyzed for all indoor interfaces.
