High Phthalates Panel Debunks Myths of DINP and DIDP
The American Chemistry Council (ACC) represents the leading companies engaged in the multibillion-dollar business of chemistry. ACC members apply the science of chemistry to make innovative products, technologies and services that make people's lives better, healthier and safer.
ACC’s High Phthalates Panel: “CPSC Continues to Ignore the
“DINP is one of the most thoroughly studied compounds in the world. It has been reviewed by numerous international scientific panels for decades, and the conclusions are essentially the same each time: DINP, under normal use in commercial and consumer products, does not pose a risk to human health.
Di(isononyl) phthalate (DINP) and di(isodecyl) phthalate
Authors: McKee, R., Przygoda, R., Chirdon, M., Engelhardt, G., and Stanley, M This paper documented that DINP and DIDP are not mutagenic.
High Phthalates: A Primer on DINP and DIDP
Phthalates are a family of compounds some of which primarily are used to soften or “plasticize” polyvinyl chloride (PVC), or vinyl. Phthalates are used in hundreds of products in our homes, hospitals, cars and businesses. Not all phthalates are the same, however. High phthalates refer to those phthalates with a higher molecular weight, with ≥7 carbon atoms in their chemical
GreenScreen Assessment for Diisononyl phthalate (DINP) (CAS
Chemicals With Data Gaps), DINP meets requirements for a GreenScreen Benchmark Score of 1, despite the hazard data gaps. In a worst-case scenario, if DINP were assigned a High score for C, it would remain a GreenScreen Benchmark 1 chemical.

- 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.
- What is a good DINP density?
- The overall high-quality sources reported DINP density values ranging from 0.97 to 0.98 g/cm3 (NCBI, 2020; ECHA, 2016; NLM, 2015; O'Neil, 2013; NTP-CERHR, 2003; ExxonMobil, 2001; De Lorenzi et al., 1998).
- Is DINP a SVOC?
- Based on the identified Henry’s Law constant value, DINP is considered an SVOC. EPA extracted and evaluated four data sources containing DINP flash point information. Three of the sources were identified and evaluated as overall high-quality data sources and one as overall medium-quality data sources.
- What is the viscosity of DINP at 25 °C?
- In the final scope document for DINP (U.S. EPA, 2021), a value of 55.334 cP at 25 °C was identified as the viscosity for DINP (De Lorenzi et al., 1998).
- Is DINP safe?
- For consumers and the general public, the news is even more reassuring. The EPA found no risk associated with everyday exposure to DINP in typical consumer products or the environment. Household items such as flooring, textiles, automotive components, and insulation remain safe for use.
- 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).
