Endpoint:
vapour pressure
Data waiving:
study technically not feasible
Justification for data waiving:
other:
Justification for type of information:
According to hydrolysis test results, the hydrolysis rate is estimated to be within 30 minutes. The hydrolysis products have been identified to be triethanolamine and zirconium dioxide.
The target substance was a highly viscous liquid (dynamic viscosity c.a. 27000 mPa.s at 25°C), the vapour pressure was expected to be very low.
Testing would record the results of the key degradation products which are relatively volatile, including triethanolamine.
Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Justification for type of information:
Triethanolamine is the main hydrolysis prodcuts of the target substance. Properties of the hydrolysis are used for read-across.

Key result
Temp.:
ca. 20 °C
Vapour pressure:
< 0.01 mm Hg
Conclusions:
The vapor pressure of triethanolamine is less than 0.01 mmHg (1.33 Pa) at 20°C according to published data.

Additional information

According to hydrolysis test results, the hydrolysis rate was estimated to be less than 30 minutes. The hydrolysis products had been identified to be 2,2',2''-Nitrilotriethanol (triethanolamine) and titanium dioxide.

The boiling point of triethanolamine was chosen for CSA.
