Chemical compound
Tris(2-ethylhexyl)phosphate (TEHP
[2]) is an organic
chemical compound in the
organophosphate group. It is a triakylphosphate.
Occurrence
Since tris(2-ethylhexyl) phosphate is easily separated from
polymers, it is often found in
house dust
[3]
Properties
Tris(2-ethylhexyl) phosphate is a colourless,
viscous liquid with a faint, piercing smell. It has a viscosity of 15 mPas at 20 °C.
[4]
Uses
Due to its properties (including that it is a mild
biocide), tris(2-ethylhexyl)phosphate is used in a variety of applications:
Safety
When heated above its
flash point of 170 °C, TEHP can release vapours capable of forming
explosive mixtures with air.
[6]
Several studies concluded that TEHP has the highest
bioaccumulation factor of all
organophosphate
flame retardants examined.
