Phototransformation in air

Description of key information
Phototransformation in air is not relevant due to low vapour pressure (< 0.0001 Pa).
Key value for chemical safety assessment
Additional information
No experimental studies investigating the phototransformation in air of tetradecanoic acid, tetradecyl ester (CAS 3234-85-3) are available. Results from AOPWIN v1.92 indicate that the substance is susceptible to indirect photodegradation in air. The estimated half-life for the reaction with OH-radicals is 11.16 h (24 h day; OH-concentration: 0.5E+06 OH/cm³) (Müller, 2011). However, this is not expected to be a relevant environmental fate process, since tetradecanoic acid, tetradecyl ester is not expected to enter the atmospheric compartment based on the low estimated vapour pressure under ambient conditions (< 0.0001 Pa at 20 °C).
As this study is not a standard information requirement in REACh and there is no indication from the Chemical Safety Assessment (CSA) on the need to investigate further the fate and behaviour of the substance (Annex X requirement), no further testing is considered necessary for tetradecanoic acid, tetradecyl ester.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
