The vapor pressure of Formaldehyde, oligomeric reaction products with
4,4'-isopropylidenediphenol and diethylenetriamine (EK110) has been
determined to be 136 Pa at 25 °C, using the vapor pressure balance
method, designed to be compatible with Method A.4 Vapour Pressure of
Commission Regulation (EC) No 440/2008 of 30 May 2008, and Method 104 of
the OECD Guidelines for Testing of Chemicals, 23 March 2006. There was
a general drop in vapor pressure observed on repeated temperature
cycling of the test item with
individual values in the range 136 to 25 Pa at 25°C for nine consecutive
runs. Such characteristics, indicative of the gradual reduction of a
more volatile fraction in the test item was as anticipated based on the
complex composition of the test item. To provide representative
data for risk assessment on accidental release of the test item, the
highest value obtained has been taken as the definitive result.
The vapor pressure of the test item has been determined to be 136 Pa at
