Federal Register :: Addition of Diisononyl Phthalate Category
The DINP category is a family of di-ester phthalates widely used as plasticizers. These chemicals are colorless, oily liquids with high boiling points, low volatilities, and are poorly soluble in water (less than 10 4 milligrams per liter (mg/L)).

Federal Register :: Di-isononyl Phthalate (DINP); Manufacturer Request
What is di-isononyl phthalate (DINP)? DINP is a phthalate used as a plasticizer and paint additive in consumer and commercial products, as well as numerous manufacturing applications. There are two commercial products the manufacturer submitted for risk evaluation under the name DINP.
76072 Federal Register /Vol. 85, No. 229/Friday, November 27
for di-isononyl phthalate (DINP) (1,2- benzene-dicarboxylic acid, 1,2- diisononyl ester, and 1,2- benzenedicarboxylic acid, di-C8–10- branched alkyl esters, C9-rich; Chemical Abstracts Service Registry Number (CASRN) 28553–12–0 and CASRN 68515–48–0) a category of chemical substances for which EPA received a manufacturer request for risk
- What does TSCA stand for in diisononyl phthalate (DINP)?
- The Environmental Protection Agency (EPA or Agency) is announcing the availability of the final risk evaluation under the Toxic Substances Control Act (TSCA) for diisononyl phthalate (DINP) (1,2-Benzene- dicarboxylic acid, 1,2- diisononyl ester) (CASRN 28553- 12-0).
- What does DINP stand for?
- Environmental Protection Agency (EPA). Notice. The Environmental Protection Agency (EPA or Agency) is announcing the availability of and seeking public comment on a draft risk evaluation under the Toxic Substances Control Act (TSCA) for di-isononyl phthalate (DINP) (1,2-Benzene- dicarboxylic acid, 1,2- diisononyl ester) (CASRN 28553-12-0).
- What is DINP phthalic acid (Diisodecyl phthalate)?
- DINP is typically a mixture of chemical compounds consisting of various isononyl esters of phthalic acid, and is commonly used in a large variety of plastic products. The European Union has set a maximum specific migration limit (SML) from food contact materials of 9 mg/kg food for the sum of diisononyl phthalates and diisodecyl phthalates.
- Does Di-isononyl phthalate (DINP) warrant classification for reprotoxic effects?
- The ECHA 's Risk Assessment Committee (RAC) has concluded, on March 7, 2018, that Di-isononyl phthalate (DINP) does not warrant classification for reprotoxic effects under the EU's Classification, Labelling and Packaging (CLP) regulations.
- Did EPA request a risk evaluation for DINP & DIDP?
- On May 24, 2019, EPA received requests to conduct risk evaluations for both DINP and DIDP from ExxonMobil Chemical Company, Evonik Corporation, and Teknor Apex, through the American Chemistry Council's High Phthalates Panel (ACC HPP). In December 2019, EPA notified ACC HPP that the Agency had granted their manufacturer requested risk evaluations.
- Are DIDP and DINP phthalates structurally similar?
- DIDP and DINP are both structurally similar phthalates, and therefore many aspects of physical-chemical (p-chem) properties and exposure (to humans and ecological species) are similar, as described further in the draft physical chemical and fate assessments for both chemical substances. B.
