Bis(2-ethylhexyl) phthalate
Due to its suitable properties and the low cost, DEHP is widely used as a plasticizer in manufacturing of articles made of PVC. [8] Plastics may contain 1% to 40% of DEHP. It is also used as a hydraulic fluid and as a dielectric fluid in capacitors. DEHP also finds use as a solvent in glowsticks .

Diethylhexyl phthalate - GreenFacts
DEHP is a chemical form of dioctyl phthalate or DOP DEHP has the same core structure as DBP, DIDP and DINP, but has longer, branched side chains attached, each having 8 carbon atoms. DEHP is a colourless oily liquid. It is soluble in fat and not very soluble in water. The same information on Level 1: Summary Level 2: Details Level 3: Source 2.
5 Most important facts about Dioctyl phthalate (DOP) - Ideh
Dioctyl phthalate (DOP), also known as diethylhexyl phthalate (DEHP), is an organic compound with the molecular formula C6H4 (CO2C8H17). Dioctyl phthalate, characterized by its molecular weight, high boiling point, and low vapor pressure, is one of the most widely used general emollients.
1. What are the properties of diethylhexyl phthalate (DEHP)?
The limited data available on purity indicates a high purity level (99.7%). Impurities found are mainly other phthalates. Some DEHP is, when requested by the user, supplied with "Bisphenol A"; 4,4’-isopropylidenediphenol (CAS No. 80-05-7) as an additive in the range of 0.025 to 0.5%. 1.3 PHYSICO-CHEMICAL PROPERTIES
- What is DEHP/DOP used for?
- It is a broad-spectrum plasticizer used mostly to render polyvinyl chloride products soft, pliable, and durable. DEHP/DOP is the most widely used plasticizer in the manufacture of many vinyl products, including disposable gloves. Q: Why is there increased interest in DEHP/DOP?
- Is DEHP a natural hazard?
- DEHP is not known to occur naturally. 1.3.2. Occupational exposure According to the 1981–83 National Occupational Exposure Survey, 341 800 workers in the USA were potentially exposed to DEHP. Occupational exposure to DEHP may occur during its manufacture and its use, mostly as a plasticizer of PVC (compounding, calendering and coating operations).
- What are the metabolites of DEHP?
- In a follow-up report, the levels of three metabolites of DEHP were measured in the urine of the 54 infants. Urinary concentrations stratified by intensiveness (in ng/mL) were: MEHP – low, 4; medium, 28; high, 86; MEHHP – low, 27; medium, 307; high, 555; and MEOHP – low, 29; medium, 286; high, 598.
- How much DEHP is in plastic?
- Plastics may contain from 1 to 40% DEHP by weight. An estimated 90% of DEHP is used as a plasticizer for polyvinyl chloride (PVC) polymers (Toxics Use Reduction Institute, 2005). In the EU, 95% of DEHP is used as a plasticizer in polymer products (European Commission, 2008).
- What is the concentration of DEHP in freshwater?
- In general, concentrations of DEHP in freshwater are in the range of < 0.1–10 μg/L, although occasionally much higher values have been observed (|100 μg/L) when water basins are surrounded by large numbers of industrial plants (WHO, 1992).
- Where is DEHP found?
- Levels of up to 1.9 μg/L DEHP were found in rivers of the greater Manchester area, United Kingdom (Fatoki & Vernon, 1990), and at unspecified levels as contaminants in all the samplings of the Elbe River and its tributaries in Germany during the period 1992–94 (Franke et al., 1995).
