None of the studies on the physical and chemical properties of this substance resulted in a classification.

Property	Results	Value used for CSA / Discussion
Physical state at 20°C and 1013 hPa	Evernox 1135 is a colourless to slightly yellow liquid.	Value used for CSA:liquid
Melting / freezing point	The freezing point was determined to be -44.2°C.	At -44.2°C the substance passes from a liquid to a glass state.
Boiling point	The boiling point was found to be 343°C.	Value used for CSA:343 °C at 1013 hPa The result was determined by extrapolation.
Relative density	The relative density of Evernox 1135 was found to be 0.97.	Value used for CSA:0.97 at 20°C
Vapour pressure	The vapour pressure was found to be 0.0015 Pa at 25°C and 11 Pa at 127°C	Value used for CSA:0.0015 Pa at 25 °C
Surface tension	The surface tension of a 9.87 g/l emulsion was found to be 66.9 - 68.7 mN/m.	Value used for CSA:67.8 mN/m at 20°C and 9870 mg/L
Water solubility	The water solubility was found to be < 0.03 mg / l at 20°C and pH 6.4.
Partition coefficient n-octanol/water (log value)	The log Pow of Evernox 1135 was found to be 9.2 at 0°C.	Value used for CSA:Log Kow (Pow): 9.2 at 0 °C
Flash point	The flash point was determined to be 152°C, no data on atmospheric pressure was given.
Flammability	Evernox 1135 was found to be non-flammable.	Value used for CSA: non flammable
Explosive properties	Evernox 1135 was determined to be non-explosive.	Value used for CSA:non explosive
Self-ignition temperature	The autoflammability temperature of Evernox 1135 is 365°C. There is no data for atmospheric pressure.
Oxidising properties	Evernox 1135 was determined from its chemical structure to be non-oxidising.	Value used for CSA:Oxidising: no In accordance with column 2 of REACH Annex VII, the study does not need to be conducted because on the basis of its chemical structure, the substance is incapable of reacting exothermically with combustible materials.
Granulometry	Study not undertaken because Evernox 1135 is a liquid.
Stability in organic solvents and identity of relevant degradation products	Study waived; According to Reach Annex IX, column 1 of end point 7.15, this study is only required if stability of the substance is considered to be critical. Stability in solvents is not critical for this substance.
Dissociation constant	Study waived; In accordance with section 1 of REACH Annex XI, the dissociation constant study does not need to be performed because the substance does not contain any ionic structure.
Viscosity		Value used for CSA:Viscosity at 20°C: 635 mPa · s (dynamic)
