Additional information

Based on its physical chemical properties, 2 -ethylhexyl diphenyl phosphate can not be classified as hazardous for physical-chemical hazards according to the criteria of Directive 67/548/EEC.

Based on its physical chemical properties, 2 -ethylhexyl diphenyl phosphate can not be classified as hazardous for physical-chemical hazards according to the criteria of GHS/CLP regulation 1272/2008/EC.

2 -ethylhexyl diphenyl phosphate is a clear, odourless liquid at room temperature.

The melting point of 2 -ethylhexyl diphenyl phosphate is -30 degrees Celsius.

The boiling point of 2-ethylhexyl diphenyl phosphate is 239 degrees Celsius at 10 mm Hg.

The density of 2-ethylhexyl diphenyl phosphate is 1.091 g/ml at 25 degrees Celsius.

The vapour pressure of 2-ethylhexyl diphenyl phosphate is 0.2 mm Hg at 150 degrees Celsius.

The log Kow of 2 -ethylhexyl diphenyl phosphate is 5.87 at 25 degrees Celsius.

The water solubility of 2 -ethylhexyl diphenyl phosphate is 50.6 ug/l at 23.5 degrees Celsius and pH 6.80.

The surface tension of 2 -ethylhexyl dihenyl phosphate is 36.7 dyn/cm at 23 degrees Celsius.

The flash point (determined by Cleveland open cup method) of 2 -ethylhexyl diphenyl phosphate is 224 degrees Celsius.

The viscosity of 2 -ethylhexyl diphenyl phosphate is 16.4 mm^2/s at 25 degrees Celsius.

In accordance with REACH Annex VII column 2, the autoflammability test (required under 7.12) does not need to be conducted as the flash point of 2-ethylhexyl diphenyl phosphate is > 200 degrees Celsius and the substance is not flammable in air.

In accordance with column 2 of REACH Annex VII, the explosiveness study (required in section 7.11) does not need to be conducted as 2-ethylhexyl diphenyl phosphate does not contain chemical groups indicating explosive properties (as mentioned in the ECHA endpoint specific guidance).

In accordance with column 2 of REACH Annex VII, the oxidising properties study (required in section 7.13) does not need to be conducted as the 2-ethylhexyl diphenyl phosphate molecule contains oxygen which is chemically bonded only to carbon and phosphorus. Thus according to Technical Guidance Document 7A it can be concluded beyond a reasonable doubt that 2-ethylhexyl diphenyl phosphate is not an oxidizing liquid capable of causing fire or enhancing the risk of fire when in contact with combustible material.
