2. How are DIDP and DINP used? - GreenFacts
An increase of the consumption of DIDP is to be expected over the following years. Approximately 95% of DIDP are used in PVC as a plasticizer. The remaining 5% are used in non-PVC applications. More than half of the DIDP used in non-PVC applications involves polymer -related uses (e.g. rubbers).
DINP-DIDP: 2. How are DIDP and DINP used? - GreenFacts
Around 95% of DIDP and DINP is used in PVC as a plasticizer. More than half of the remaining 5% involves polymer -related uses other than PVC (e.g. rubbers). The remaining DIDP and DINP are used in non-polymer applications including anti-corrosion paints, anti-fouling paints, lacquers, inks, adhesives and sealants .
Plasticizers: Types, Uses, Classification, Selection & Regulation
DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates. They are made from aliphatic dibasic acids such as adipic acid and alcohols. Benzoate Esters – They are esterification products of benzoic acid and selected alcohols or diols.
EPA Publishes Final Risk Evaluation for DIDP and DINP
EPA Publishes Final Risk Evaluation Scope Documents for DIDP and DINP. Friday, September 3, 2025. On August 31, 2025, the U.S. Environmental Protection Agency (EPA) announced the availability of
Risk Evaluation for Di-isodecyl phthalate (DIDP) (1,2-Benzene
Background on DIDP. DIDP is a common chemical name for the category of chemicals that includes the following substances: 1,2-benzenedicarboxylic acid, 1,2-diisodecyl ester and 1,2-benzenedicarboxylic acid, di-C9-11-branched alkyl esters, C10-rich. The primary use for DIDP is as a plasticizer in plastic and rubber products.
- What are non-PVC applications for DINP?
- Approximately 95% of DINP are used in PVC as a plasticizer. The remaining 5% are used in non-PVC applications. In non-PVC applications, more than half of the DINP is used in polymer-related uses (e.g. rubbers). The remaining DINP is used in non-polymer applications including inks, adhesives and sealants, paints and lacquers.
- How much of DIDP is used in non-PVC applications?
- Approximately 5% of DIDP is used in non-PVC applications. More than half of this amount is used in polymer-related applications, such as rubbers.
- What is DIDP used for in non-PVC applications?
- In non-PVC applications, DIDP is used for anti-corrosion paints, anti-fouling paints, sealing compounds, and textile inks. More than half of DIDP is used in polymer-related applications (e.g., rubbers).
- In what applications other than PVC is DINP used?
- Approximately 95% of DINP is used in PVC as a plasticizer. The remaining 5% is used in non-PVC applications. More than half of the DINP used in non-PVC applications involves polymer -related uses (e.g. rubbers).
- How many tonnes of DIDP and DINP are produced each year?
- In 1994, over 200 000 tonnes of DIDP and 107 000 tonnes of DINP were produced annually in the European Union, and production is expected to increase further.
- What is the difference between DIDP and DINP?
- DIDP and DINP are acronyms that each refer to certain mixtures of phthalates. Most of the molecules in DIDP have 10 carbon atoms, while those in DINP have 9 carbon atoms. They have a common core structure with two long chains of molecules attached to the core.
