List of Manufacturer-Requested Risk Evaluations under TSCA
Diisononyl Phthalate (DINP) On May 24, 2025, EPA received a request from the ExxonMobil Chemical Company, Evonik Corporation, and Teknor Apex, through the American Chemistry Council’s High Phthalates Panel, to conduct a risk evaluation for diisononyl phthalate (DINP).
VESTINOL 9 DINP (Diisononyl Phthalate) - The Chemical Company
Diisononyl Phthalate (DINP) C6H4(COOC9H19)2, is a clear, colorless, and almost odorless liquid chemical. It is soluble in most organic solvents. DINP is primarily used as a PVC plasticizer. As compared to DOP, the low volatility and better endurability of DINP significantly reduces the fume emissions during the processing procedure and improves its permanence in the final product. Applications
Jayflex plasticizers for advantaged performance
Jayflex DINP and DIDP are di-esters with a chemical structure providing an optimum balance between polar and non-polar groups. Key characteristics of the plasticizer are very slow diffusion and outstanding permanence derived from two high molecular weight branched alcohol chains. Safe and registered under REACH
Federal Register :: Addition of Diisononyl Phthalate Category
The DINP category for purposes of this action is a category of chemicals that includes the branched alkyl di-esters of 1,2 benzenedicarboxylic acid in which the alkyl ester moieties contain a total of nine carbons. The DINP category is a family of di-ester phthalates widely used as plasticizers.

Chemical Markets Update. The American Chemistry Council The ACC is conducting a webinar on March 6, 2014 at 11 AM Eastern time regarding the topic of the DINP to the California “Propisition 65” list of chemicals “known to the State to cause cancer.” This listing passed despite the weight of scientific evidence to the contrary.
- Is DINP soluble in organic solvents?
- It is soluble in most organic solvents. DINP is primarily used as a PVC plasticizer. As compared to DOP, the low volatility and better endurability of DINP significantly reduces the fume emissions during the processing procedure and improves its permanence in the final product.
- What does DINP stand for?
- Diisononyl Phthalate (DINP) C6H4 (COOC9H19)2, is a clear, colorless, and almost odorless liquid chemical. It is soluble in most organic solvents. DINP is primarily used as a PVC plasticizer.
- What is vestinol 9 DINP?
- Vestinol® 9 DINP (Diisononyl Phthalate) is a phthalate ester used mainly as a plasticizer. Plasticizers are substances added to plastics to increase their flexibility, transparency, durability, and longevity. They are primarily used to soften polyvinyl chloride.
- What is DINP used for?
- DINP is a mixture of isomers composed of 9-carbon in length, such as isononyl alcohol DINP is a general purpose plasticizer with a broad range of applications used in flexible PVC. It is widely used in the toy, construction, and general consumer product markets. It has limited use in food packaging and is not used in medical applications.
- Where can I ship vestinol® 9 DINP (diisononyl phthalate) plasticizer?
- Vestinol® 9 DINP (Diisononyl Phthalate) Plasticizer is available for shipping throughout the continental United States with 1 week lead time. Please call (401) 360-2800 for details. The product is delivered in metal drums by truck and railcar, and bulk tanker trucks.
- What percentage of DINP is used in PVC?
- Specifically, approximately 95 percent of DINP produced is used in PVC as a plasticiser. More than half of the remaining 5 percent is used in the production of polymers other than PVC (e.g. rubber). The remaining DINP is used in non-polymer applications including anti-corrosion paints, anti-fouling paints, lacquers, inks, adhesives and sealants.
