Phthalates - ECHA - Europa
Phthalates Phthalates Phthalates form a family of synthetic chemicals with a wide variety of uses, ranging from consumer to industrial products. There are different kind of phthalates and they are commonly used as softeners to make plastics, such as PVC, more flexible and durable.
Diisononyl phthalate
Diisononyl phthalate ( DINP) is a phthalate used as a plasticizer. DINP is typically a mixture of chemical compounds consisting of various isononyl esters of phthalic acid, and is commonly used in a large variety of plastic items. Health Issues [ edit]
Addition of Diisononyl Phthalate Category Proposed Rule
Rule Summary. 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.
Biomonitoring Summary | CDC
Di-isononyl Phthalate. CAS No. 28553-12-0. General Information. Di-isononyl phthalate (DiNP) is a mixture of phthalates with branched alkyl side chains of varying length (C8, C9, and C10). DiNP is primarily used to produce flexible plastics and has replaced di-2-ethylhexyl phthalate (DEHP) in some plastics, though not in medical products.
- What are high molecular-weight phthalates (DINP) and diisodecyl phthalate (D?
- High molecular-weight phthalates, such as diisononyl phthalate (DINP), and diisodecyl phthalate (DIDP), are widely used as plasticizers in the manufacturing of polymers and consumer products. Human biological monitoring studies have employed the metabolites of DINP and DIDP as biomarkers to assess human exposure.
- What is DINP phthalic acid (Diisodecyl phthalate)?
- DINP is typically a mixture of chemical compounds consisting of various isononyl esters of phthalic acid, and is commonly used in a large variety of plastic products. The European Union has set a maximum specific migration limit (SML) from food contact materials of 9 mg/kg food for the sum of diisononyl phthalates and diisodecyl phthalates.
- Are Diisodecyl-phthalate and diisononyl phthalate safe?
- Diisodecyl-phthalate (DIDP) and Diisononyl-phthalate (DINP) are not considered safe as their widespread use in everyday products has raised concerns about their safety. They are mainly used as additives in plastics to make them more flexible.
- What is diisononyl phthalate (DINP)?
- Diisononyl phthalate (DINP) has been widely used in polyvinyl chloride (PVC) products and is ubiquitous as a substitute; however, its toxicity due to exposure remains to be determined.
- What are Di-isononyl phthalate esters (dinps)?
- Di-isononyl phthalate esters (DINPs) are endocrine-disrupting chemicals and have replaced di (2-ethylhexyl) phthalate (DEHP) as the major plasticizer for poly (vinyl chloride) (PVC) products in recent years. Exposure marker discovery of DINPs is crucial, because of their high potential for human exposure and toxicity.
- Is DINP a phthalate?
- Its profile in terms of processability, performance, availability and economics makes DINP a “general purpose” phthalate, such as DEHP or DIDP. DINP (and DIDP) also show a particular compatibility for uses requiring long term performance or durability.
