HIGH PHTHALATES: A PRIMER ON DINP AND DIDP
High phthalates refer to those phthalates with a higher molecular weight, with ≥7 carbon atoms in their chemical backbone, which gives them increased permanency and durability. The most common types of high phthalates include diisononyl phthalate (DINP) and diisodecyl phthalate (DIDP).
High Phthalates: A Primer on DINP and DIDP
High Phthalates: A Primer on DINP and DIDP Phthalates are a family of compounds some of which primarily are used to soften or “plasticize” polyvinyl chloride (PVC), or vinyl. Phthalates are used in hundreds of products in our homes, hospitals, cars and businesses. Not all phthalates are the same, however.

High-molecular-weight phthalates are di 2-ethylhexyl phthalate (DEHP), diisononyl phthalate (DiNP), diisodecyl phthalate (DiDP), and diisoundecyl phthalate (DiUP). Infant exposure can occur at the beginning of life via medical equipment for hospitalized babies, infant formulas, and breastfeeding [ 9 , 69 , 70 , 71 ].
The Next PFAS? Research Heightens Concerns Over Phthalates
The American Chemistry Council contends that “the safe use of DINP, DIDP and DPHP [three commonly used phthalates in PVC] in consumer and industrial applications has been supported by scientific bodies of government and independent agencies in both Europe and the United States.”
High Phthalates Panel Debunks Myths of DINP and DIDP
“In reality, high-molecular weight (HMW) phthalates such as DINP and DIDP have developed a very strong safety profile during the 50 years in which they have been in use. In December 2025, the European Food Safety Authority (EFSA) released an updated food safety assessment of phthalates (including DINP and DIDP) used in food contact materials
- What is Diisodecyl phthalate (DIDP)?
- ?
- ) Diisodecyl phthalate (DIDP) is a commonly used plasticizer used in the production of plastic and plastic coating to increase flexibility. It is a mixture of compounds derived from the esterification of phthalic acid and isomeric decyl alcohols.
- Is DIDP a phthalate?
- The coating on furnishings, cookware, pharmaceutical pills, food wrappers and many other products may have DIDP or other phthalates in them. There has been recent concern in the US and European Union for their toxicity and bioaccumulative quality.
- What are the different types of High phthalates?
- Common types of high phthalates include diisononyl phthalate (DINP) and diisodecyl phthalate (DIDP). Colorless, odorless high phthalates are used in a multitude of products that demand high performance, long-lasting wear and durability.
- What temperature is Diisodecyl phthalate (DIDP)?
- Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?
- ) Diisodecyl phthalate (DIDP) is a commonly used plasticizer used in the production of plastic and plastic coating to increase flexibility.
- What is phthalic acid (DIDP)?
- It is a mixture of compounds derived from the esterification of phthalic acid and isomeric decyl alcohols. The coating on furnishings, cookware, pharmaceutical pills, food wrappers and many other products may have DIDP or other phthalates in them.
- What is the High Phthalates Panel?
- The High Phthalates Panel is dedicated to promoting the benefits of high phthalates, specifically DINP, DIDP, and DPHP. The term ‘phthalate’ refers to a family of chemicals, but the High Phthalates Panel focuses on these three members.
