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).

Diisononyl Phthalate (DINP) - Proposition 65 Warnings Website
DINP is one of the phthalates most frequently used in plastic products. Some polyvinyl chloride (PVC, vinyl) flooring, materials used in automobile interiors, wire and cable insulation, gloves, tubing, garden hoses, and shoes. DINP is also used in some non-PVC products, such as some inks and pigments, adhesives, sealants, paints and lacquers.
- What is diisononyl phthalate (DINP)?
- Diisononyl phthalate (DINP) is a dialkyl phthalate plasticizer that has been used in children's products made from polyvinyl chloride (PVC), such as teethers and toys. It is one of the plasticizers that can migrate from children's toys, child care articles, art materials, and school supplies.
- Is diisononyl phthalate used as a plasticizer?
- Diisononyl phthalate (DINP) is used as a plasticizer in children's products made from polyvinyl chloride (PVC), such as teethers and toys. Children may be exposed to phthalates when handling or mouthing PVC products because plasticizers are not covalently bound.
- What is DINP plasticizer?
- Quality guaranteed, find your speciality chemicals with ease. 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.
- What is the difference between DOP and DINP plasticizer?
- DINP is a preferred replacement for DOP plasticizer, and is highly compatible with PVC and shows good permanence. When compared to DOP, DINP has lower volatility, improved cold temperature flexibility, and better permanence in the final product.
- Why is DINP used in plastisols?
- Due to its low volatility characteristics, DINP is indicated in the formulation of Plastisols for automotive and machinery presses as they maintain paste viscosity for a long period of time.
- Is DINP industrialized for third parties?
- Industrialized for third parties. DINP is a primary monomeric plasticizer of high molecular weight with moderate viscosity and low volatility.
