Diisononyl phthalate (DINP) is a high-molecular-weight phthalate ester, a chemical used to increase the flexibility and longevity of plastics, particularly PVC. Its primary function is to act as a plasticizer, a substance added to a material to make it softer and more pliable. At room temperature, it is a clear, transparent, oily liquid with a faint odor. It is found in a wide range of consumer products such as flooring, auto parts, and wire insulation.

The major driver of the DINP market is its application in PVC processing as a plasticizer. According to Plastics Europe AISBL, in 2023, the PVC production reached around 53 million tons, a 6% increase from 50 million tons in 2020. As PVC production increases, there is consistent demand for diisononyl phthalate. While it’s used in many applications, its use in children’s toys and childcare articles that can be mouthed is restricted in such as regions due to health concerns by regulatory authorities.

These regulatory frameworks work mainly against phthalates and pose a significant challenge to the industry. However, as the laws regarding phthalates grow stringent, there is a focus on the production of DINCH plasticizer, which is safer and eco-friendly than DINP, and is produced from the hydrogenation of DINP.

• Within the European Economic Area alone, in 2022, according to the European Chemicals Agency (ECHA), DINP production was registered, including importing and manufacturing, as being between 100,000 and 1,000,000 tons per year.
