Description of key information

The sum of vapour pressures of the organic constituent of the registration substance is < 0.1% (<0.05 Pa) of total vapour pressure.
For iso-C12-monophosphoricacid ester vapour pressure was calculated to be 0.0000138 Pa at 25 °C, 6.52 Pa at 160 °C and 23.3 Pa at 180 °C.

Key value for chemical safety assessment

Additional information

According to the calculated vapour pressures ( at 25 °C) of the constituents of the registration substance, the vapour pressure of the impurity water has a share of >99,9% of the total vapour pressure. The sum of vapour pressures of the organic constituent of the registration substance is < 0.1% (<0.05 Pa) of total vapour pressure.

For iso-C12-monophosphoricacid ester vapour pressure was calculated to be 0.0000138 Pa at 25 °C (Epi), 6.52 Pa at 160 °C and 23.3 Pa at 180 °C (Clausius-Clapeyron).
