Bis (2-ethylhexyl) phthalate

Bis(2-ethylhexyl) phthalate (DEHP), or di-2-ethylhexyl phthalate, diethylhexyl phthalate and diisooctyl phthalate, is the most common member of the class of phthalates, colouress and soluble in oil. It is used primarily as a plasticiser used in plastic products but also as a carrier.

DEHP is most commonly used in polyvinyl chloride (PVC) plastic products; upholstery, shower curtains, adhesives, pipes, and coatings but the amount can vary from 0.1% to 40%. It has also been used in food packaging, medical tubes or containers, inks, pesticides, pump oils as well as being used to carry scent in household and cosmetic products, such as air fresheners, personal hygiene products and scented home wear items.

DEHP exposure for workers who repeatedly inhale, or have skin contact with the substance can have toxic effects on the testis, fertility and kidney. Exposure can also come from the contamination of foods, and liquids, especially where foods are oily in consistence and stored in plastic containing DEHP. Such exposure may may increase the risk of cancer, harm male reproductive system and cause birth defects, effecting the development of children during pregnancy.

DEHP is covered by the EU and UK Restriction of Hazardous Substances in Electrical and Electronic Equipment (RoHS) directive and regulations, meaning its use is restricted to 0.1% in products through application and monitored, along with other substances that include lead, cadmium, mercury, Hexavalent chromium and polybrominated diphenyl ethers (PBDE), Polybrominated biphenyls (PBBs), butyl benzyl phthalate (BBP), dibutyl phthalate (DBP) and diisobutyl phthalate (DIBP).
