Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
Additional information
In accordance with Annex X of the Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals, phototransformation in air is not a mandatory information requirement.
Although phototransformation in air is not a mandatory information requirement, calculated data for the representative constituent category of Alchisor TAL 111 (C9 -C14 aliphatics (2 -25% aromatics)) is available. In the case of C9-C14 aliphatics (2 -25% aromatics), indirect photochemical degradation of these hydrocarbons as mediated by OH-attack, is estimated to have a half-life of 0.09 to 1.43 days, or 1.10 to 17.25 hours, based on a 12-hour sunlight day, a rate of 7.4×10-12to 116.3×10-12cm3/mol/sec, and an average OH-concentration of 1.5×106OH/cm3. A 12-hour day half-life value normalizes degradation to a standard daylight period during which hydroxyl radicals needed for photolysis are generated in the atmosphere.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
