Bis(2-ethylhexyl) phthalate
Bis (2-ethylhexyl) phthalate ( di-2-ethylhexyl phthalate, diethylhexyl phthalate, diisooctyl phthalate, DEHP; incorrectly — dioctyl phthalate, DIOP) is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. DEHP is the most common member of the class of phthalates, which are used as plasticizers. It is the diester of phthalic acid
Plasticizer
Good high temperature and outdoor weathering performance Ditridecyl phthalate (DTDP) is the highest molecular weight phthalate plasticizer, providing greater performance at high temperature. It is the preferred plasticizer for automotive cable and wire application. Terephthalates [ edit]
5 Most important facts about Dioctyl phthalate (DOP)
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.
Plasticizers: Types, Uses, Classification, Selection & Regulation
DEHP offers good gelling, satisfactory electrical properties and helps to produce highly elastic compounds with reasonable cold strength. It displays fairly good flexibility at low temperatures and some resistance to high-temperature. However, DEHP is listed by the IARC as a human carcinogen.
Benefits, Trends, Health, and Environmental Issues - ChemistryViews
Only four low orthophthalates – di (2-ethylhexyl)phthalate (DEHP), dibutyl phthalate (DBP), diisobutyl phthalate (DIBP), and n-butyl benzyl phthalate (BBP) – have been found to have any adverse endocrine-related effects in laboratory animal studies with specific thresholds.
- What is DEHP used for?
- DEHP is used in large quantities, primarily as a plasticizer for polyvinyl chloride and other polymeric materials. Disposal of these products (incineration, landfill, etc) will result in the release of DEHP into the environment. DEHP has been detected in the effluent of numerous industrial plants.
- Where does DEHP come from?
- DEHP has been detected in the effluent of numerous industrial plants. From 1987 to 1993, according to EPA's Toxic Chemical Release Inventory, DEHP releases to land and water totalled over 500,000 lbs., of which about 95 percent was to land. These releases were primarily from rubber and plastic hose industries .
- Does DEHP bioconcentrate?
- DEHP does have a tendency to bioconcentrate in aquatic organisms; the experimental BCF values range from a log of 2 to 4 in fish and invertebrates. In fathead minnows the log BCF was 2.93; in bluegill sunfish it was 2.06 .
- Why is DEHP used in PVC tubing?
- PVC is naturally rigid, but plasticizers are added to make the tubing flexible and expandable while retaining its shape. DEHP is widely used because it is low cost, processes well, and has provided good end-use performance. Why is Saint-Gobain Performance Plastics developing alternative tubing products that do not contain DEHP?
- Can DEHP cause cancer?
- Chronic: DEHP has the potential to cause the following health effects from long-term exposures at levels above the MCL: damage to liver and testes; reproductive effects. Cancer: There is some evidence that DEHP may have the potential to cause cancer from a lifetime exposure at levels above the MCL.
- What are the health effects of Di 2 ethylhexyl phthalate (DEHP)?
- Acute: EPA has found di (2-ethylhexyl) phthalate (DEHP) to potentially cause the following health effects from acute exposures at levels above the MCL: mild gastrointestinal disturbances, nausea, vertigo.
