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]
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.
Bis(2-ethylhexyl) phthalate
DEHP is the most common phthalate plasticizer in medical devices such as intravenous tubing and bags, IV catheters, nasogastric tubes, dialysis bags and tubing, blood bags and transfusion tubing, and air tubes. DEHP makes these plastics softer and more flexible and was first introduced in the 1940s in blood bags.

DEHP is found throughout the environment at low levels. It gets into the environment mostly through the disposal of plastic waste in landfills. Most DEHP in the environment is found in sediments and soil. It sticks strongly to soil and breaks down slowly when it is near the surface. Indoors, DEHP can also stick to dust particles.
1. What are the properties of diethylhexyl phthalate (DEHP)?
DEHP is a colorless liquid at room temperature. The vapour pressure is estimated to 3.4 . 10-5Pa at 20°C. A wide range of values on the water solubility (0.0006 – 1.3 mg/L at 20-25°C) is available in the literature. The probable explanation is that DEHP readily forms more or less colloidal dispersions in water.
- Where is DEHP used?
- DEHP is the world's most widely used PVC plasticizer and is used in virtually every category of flexible PVC. Where is it used?
- and blood bags to footwear, electrical cables, packaging, and flooring. Why is it used?
- Plasticizers are essential to make PVC flexible.
- 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?
- 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 be used in food contact products in Europe?
- DEHP cannot be used in food contact products, such as tubing, in Europe. This regulation is expected to impact North American food companies in the near future. Additionally, consumer and environmental advocacy groups have aggressively attacked the use of DEHP in the mainstream media.
- Do you benchmark alternative materials against DEHP?
- Yes. We have taken a systematic and rigorous approach over the past year and a half to benchmark alternative materials against DEHP. Before the end of 2009, we will introduce replacements for our DEHP-containing food & beverage products.
