Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Ethyl hexyl methoxycrylene (EHMC)(EC Number 700-213-5) was tested for hydroxyl radical induced photodegradation using the EPIWIN AOP Program.  The input to this computer model was the SMILES notation for the EHMC molecule.

Key value for chemical safety assessment

Half-life in air:
3.213 h

Additional information

EPIWIN AOP (v1.92) estimates a hydroxyl radical induced photodegradation half-life for EHMC of 0.268 days or 3.213 hours, based on a 12 hour day of sunlight.and a OH radical concentration of 1.5E6 OH/cm3. The calculated overall OH rate constant is 39.9464 E-12 cm3/molecule-sec.
