EPA Releases Proposed Rule Requiring TRI Reporting on DINP
Released on August 8, 2025. Today, the U.S. Environmental Protection Agency (EPA) issued a supplemental proposed rule that would add a Diisononyl 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 and the
Risk Evaluation for Di-isononyl phthalate (DINP) (1,2-Benzene
DINP is a common chemical name for the category of chemicals that includes the following substances: 1,2-benzenedicarboxylic acid, 1,2-isononyl ester and 1,2-benzenedicarboxylic acid, di-C9-11-branched alkyl esters, C9-rich. The primary use for DINP is as a plasticizer in plastic and rubber products.

Overall, phthalates will continue to exhibit modest growth. For example, DINP will experience growth throughout the world. World consumption of phthalate plasticizers is forecast to grow moderatley during 2025–25. Nonphthalate plasticizers are not based on phthalic acid, and have a different chemical structure and toxicological profile.

Diisononyl Phthalate - an overview | ScienceDirect Topics
Phthalate esters are a main group of plasticizers, including di- (2-ethylhexyl) phthalate (DEHP) and diisononyl phthalate (DINP) as the most widely used phthalates, which can be the subject of argument regarding their probable side effects on children’s health.
- What is DINP (diisononyl phthalate)?
- DINP (diisononyl phthalate) is a commonly used plasticizer derived from the esterification of phthalic anhydride and isononyl alcohol. Diisononyl phthalate is abbreviated as DINP. This product is a transparent oily liquid with a slight odor. This product is a general-purpose main plasticizer with excellent performance.
- What is diisononyl phthalate used for?
- Used in toxicology studies as well as risk assessment studies of food contamination that occurs via migration of phthalates into foodstuffs from food-contact materials (FCM). Diisononyl Phthalate is a general-purpose plasticizer for polyvinyl chloride. General purpose plasticizers for PVC applications and flexible vinyls.
- Who makes diisononyl phthalate?
- J & K SCIENTIFIC LTD. TOKYO CHEMICAL INDUSTRY CO., LTD. Diisononyl phthalate (CAS 28553-12-0) information, including chemical properties, structure, melting point, boiling point, density, formula, molecular weight, uses, prices, suppliers, SDS and more, available at Chemicalbook.
- Is diisononyl phthalate soluble in water?
- Insoluble in water. Diisononyl phthalate reacts exothermically with acids to generate isononyl alcohol and phthalic acid. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by interaction with caustic solutions.
- Is diisononyl phthalate flammable?
- Diisononyl phthalate is combustible. Non flammable Wash the ester with aqueous Na2CO3 then shake it with water. Ether is added to break the emulsion, and the solution is washed twice with water, and dried (CaCl2). After evaporating the ether, the residual liquid is distilled three times under reduced pressure.
- What is DINP & why is it important?
- DINP enhances the flexibility, durability, and workability of PVC products, making it a crucial ingredient in the production of cables, wires, hoses, automotive parts, flooring, and synthetic leather.
