Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The experimental study is waived. Data on main components:

- n-Octyl acrylate (2499-59-4, MW=184.28): a QSAR estimation defines a vapour pressure of 11.4 Pa. Saturated vapour concentration (Csat) at 25°C is therefore 847.45 mg/m3

- n-Decyl acrylate (2156-96-9, MW=212.34): a supportive QSAR estimation defines a vapour pressure of 1.74 Pa. Csat at 25°C is therefore 149 mg/m3.

Comparison of inhalative exposure potential of both components: the component with the highest Csat has the highest inhalative exposure potential, except if Csat is corrected by the actual concentration of this component in the reaction mass. This concentration may vary betwen registrants, and is confidential. Therefore, as a worst-case the key values (VP and MW) of n-Octyl acrylate are kept as key values for the reaction mass, without any correction for actual concentration of this component. This approach is acceptable for exposure assessment and classification and labelling. In particular, as there are no inhalative DNELs, quantification of inhalative exposure is not required.
