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.
Bis(2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2.It is a non-phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol, which is often generically referred to as octyl.
DEHT and DINCH are more hydrophobic than other phthalate alternatives such as bis(2-ethylhexyl) adipate (DEHA) and diisodecyl adipate (DIDA). Since alternative plasticizers such as DEHT and DINCH are more likely to bind to organic matter and airborne particles indoors, exposure occurs primarily through food consumption and contact with dust.

TBPH is the brominated analogue of bis(2-ethylhexyl) phthalate (DEHP). Much like TBPH, DEHP has been widely used as a plasticizer , however unlike TBPH, it is currently a restricted substance due to its endocrine disrupting properties and reproductive toxicity . [ 6 ]
DIBP can be sold as a pure substance or as a component of mixtures with other phthalate plasticizers or chemicals. Examples are dioctyl phthalate (DOP), diisononyl-phthalate (DINP), or bis(2-ethylhexyl) phthalate (DEHP). [12] It may be used as a component in formulations of several products including adhesives, paints, coatings and lubricants. [3]
The enzyme bis(2-ethylhexyl)phthalate esterase (EC 3.1.1.60) catalyzes the reaction bis(2-ethylhexyl)phthalate + H 2 O 2-ethylhexyl phthalate + 2-ethylhexan-1-ol Action of the enzyme. This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds.
Bis(2-Ethylhexyl) phthalate (DEHP) Benzyl butyl phthalate (BBP) Dibutyl phthalate (DBP) Diisobutyl phthalate (DIBP) The maximum permitted concentrations in non-exempt products are 0.1%. The new substances are also listed under the REACH Candidate list, and DEHP is not authorised for manufacturing (use as a substance) in the EU under Annex XIV ...
