What is Bis(2-ethylhexyl) phthalate？

Di(2-ethylhexyl) Phthalate (DEHP), historically and commonly referred to as Dioctyl Phthalate (DOP), is the most well-known and extensively produced phthalate plasticizer. It is manufactured by the esterification of phthalic anhydride with 2-ethylhexanol. DEHP is renowned for its excellent compatibility with polyvinyl chloride (PVC), high plasticizing efficiency, and good overall balance of properties, including low volatility, good flexibility at low temperatures, and moderate cost. It has been the industry standard for flexible PVC for decades.

COA (Certificate of Analysis):

Application:

1. Used as a primary plasticizer in a vast range of flexible PVC applications, including wire and cable insulation, flooring, wall coverings, and automotive parts.

2. Employed in the production of synthetic leather and coated fabrics.

3. Applied in the formulation of plastisols for slush molding, dip coating, and rotational casting.

4. Used in the manufacture of medical devices such as blood bags and intravenous tubing (Note: This use is now highly restricted and heavily regulated in most regions).

5. Historically used in consumer products like toys and food packaging (Note: These uses are now banned or severely restricted in many countries due to health concerns).

Safety profile:

Avoid inhalation of mists and prolonged skin contact. Use appropriate personal protective equipment (PPE) including gloves and safety glasses. Ensure excellent ventilation. It is critical to consult and strictly adhere to all applicable local, national, and international regulations (e.g., REACH, TSCA, CSPA) before considering its use.

Eye Irritation:

It can cause eye irritation.

Storage requirements:

Store in a cool, dry, well-ventilated area away from direct sunlight, heat, and ignition sources. Keep containers tightly closed to prevent moisture absorption and contamination. Recommended storage temperature: 10-40 °C. Store away from strong oxidizing agents and strong acids.

Transport & Packaging:

DEHP is typically supplied in 200 kg steel or HDPE drums and 1000 kg IBC containers. It often carries specific hazard classifications for transport (e.g., Repr. 2 according to CLP/GHS). The exact shipping classification must be verified based on the most current regulations.
