Diisononyl phthalate
Diisononyl phthalate ( DINP) is a phthalate used as a plasticizer. 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 items. Health Issues [ edit]
Exposure to di(2-ethylhexyl) phthalate and diisononyl phthalate during
Because of the wide production and use of DEHP, humans are exposed to DEHP on a daily basis. Diisononyl phthalate (DiNP) is often used as a DEHP replacement chemical, and because of the increased use of DiNP, humans are increasingly exposed to DiNP over time.
Addition of Diisononyl Phthalate Category Proposed Rule
In August 2025, EPA issued a supplemental proposed rule to add a Di-isononyl phthalate (DINP) category to the list of toxic chemicals subject to the Toxics Release Inventory (TRI) reporting requirements under the Emergency Planning and Community Right-to-Know Act (EPCRA) and the Pollution Prevention Act (PPA).
Evonik committed to general-purpose plasticizer DINP
Evonik is committed to offering customers the general-purpose plasticizer DINP (diisononyl phthalate) on a global basis. The safe and long-lasting use of plasticizers is always Evonik's top priority. Recently, Evonik joined with other manufacturers in the High Phthalates Panel (HPP), a sector group of the American Chemistry Council (ACC), in a
- What is diisononyl phthalate (DINP)?
- Diisononyl phthalate (DINP) is a mixture of isomeric compounds that are branched alkyl di-ester phthalates of 1,2-benzenedicarboxylic acid, in which the alkyl ester moieties contain a total of nine carbons. DINP is used as a plasticizer, especially in the production of polyvinyl chloride (PVC).
- What are Di-isononyl phthalate esters (dinps)?
- Di-isononyl phthalate esters (DINPs) are endocrine-disrupting chemicals and have replaced di (2-ethylhexyl) phthalate (DEHP) as the major plasticizer for poly (vinyl chloride) (PVC) products in recent years. Exposure marker discovery of DINPs is crucial, because of their high potential for human exposure and toxicity.
- Is diisononyl phthalate toxic?
- EPA released the final risk evaluation for diisononyl phthalate (DINP) under the Toxic Substances Control Act (TSCA).
- 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.
