ACC’s High Phthalates Panel: “CPSC Continues to Ignore the
WASHINGTON (November 28, 2025) — Today, the American Chemistry Council’s (ACC) High Phthalates Panel (HPP) issued the following statement on the Consumer Product Safety Commission’s (CPSC) vote to issue a final resolution concerning the CPSC’s Restriction of DINP in Toys and Child Care Articles:
High Phthalates - American Chemistry Council
The most common types of high phthalates include diisononyl phthalate (DINP), diisodecyl phthalate (DIDP) and dipropylheptyl phthalate (DPHP). Low phthalates include those with 3-6 carbon atoms in their chemical backbone. Low phthalates are commonly used in medical devices, general purpose PVC, adhesives, inks and cosmetics.
Federal Register staff’s cost-benefit analysis for continuing
interim prohibition on DINP. In March 2025, the Commission voted to approve publication in the Federal Register seeking comment regarding justification of the phthalates final rule and the staff’s cost-benefit analysis for continuing the interim prohibition on DINP. Exxon and ACC stated that they were not given an opportunity to provide
Diisononyl Phthalate (DINP) - Chemical Supplier Distributor
1.481-1.488 Application Diisononyl Phthalate (DINP) is a general use high molecular weight PVC Plasticizer which provides a good balance of cost savings and properties. DINP is a preferred replacement for DOP plasticizer, and is highly compatible with PVC and shows good permanence.
High Phthalates - Chemical Safety Facts
High phthalates, such as diisononyl phthalate (DINP) and diisodecyl phthalate (DIDP), have been thoroughly studied and reviewed by a number of government scientific agencies and regulatory bodies world-wide, which have concluded that phthalates used in commercial products do not pose a risk to human health at typical exposure levels.
- What is the market size of diisononyl phthalate (DINP)?
- The market size and forecasts for Diisononyl Phthalate (DINP) are provided in terms of value (USD Million) for all the above segments. Need a report that reflects how COVID-19 has impacted this market and its growth?
- The Global Diisononyl Phthalate (DINP) Market is projected to register a CAGR of 4% during the forecast period (2021-2026).
- What is the Revie rate for DINP?
- One overall high-quality and two overall medium studies were identified in the systematic revie process for DINP, ranging from 9.14×10-5 to 4.09×10−4 atm-m3 /mole (ECHA, 2013; Cousins et al., 2007; Cousins and Mackay, 2000).
- What is diisononyl phthalate (DINP)?
- Diisononyl Phthalate (DINP) is produced industrially by esterification of phthalic anhydride with isononyl alcohol. Diisononyl Phthalate (DINP) is used for a variety of applications in different industries. TheDiisononyl Phthalate (DINP) market is segmented by polymer type, application and geography.
- Is DINP a plasticizer?
- DINP is a clear, oily, viscous liquid with a mild odor (HSDB, 2015). As a branched phthalate ester, DINP is used as plasticizer that melts around −48 °C (NCBI, 2020; RSC, 2019; NLM, 2015; O'Neil, 2013; NTP-CERHR, 2003).
- What is a DINP melting point?
- The overall high-quality sources reported DINP melting points ranging from −48 to −43 °C (NCBI, 2020; RSC, 2019; NLM, 2015; O'Neil, 2013; NTP-CERHR, 2003). EPA selected a melting point value of −48 ± 1 °C (O'Neil, 2013) as a representative value of the identified information from the overall high-quality data sources.
- How did EPA evaluate diisononyl phthalate (DINP)?
- EPA gathered and evaluated physical and chemical property data and information according to the process described in the Systematic Review Protocol for Diisononyl Phthalate (DINP) (U.S. EPA, 2025b).
