Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Parent compound lauroyl chloride and hydrolysis product lauric acid: After evaporation or exposure to the air, the product will be slowly degraded by photochemical processes.
Key value for chemical safety assessment
Additional information
Parent compound lauroyl chloride: Based on an estimated OH radical rate constant of 15.8 E-12 cm3/(molecule*sec), the half-life of lauroyl
chloride was calculated to be 1.0 day (conditions: sensitiser for indirect photolysis: OH; 0.5 E06 OH/cm3, 24-h d; BASF SE, 2012). Based on the EPI Suite calculation the substance will be slowly degraded by photochemical processes, after evaporation or exposure to air.
This estimation refers to dry air. In mist, rain, droplets and aerosols, hydrolysis will be the major fate process of the acid chloride due to the short half-life in aqueous solution. Therefore this estimate may be of low relevance.
Hydrolysis product lauric acid: Based on an estimated OH radical rate constant of 14.0 E-12 cm3/(molecule*sec), the half-life of lauric acid was calculated to be 1.1 days (conditions: sensitiser for indirect photolysis: OH; 0.5 E06 OH/cm3, 24-h d; BASF SE, 2012). Based on the EPI Suite calculation the substance will be slowly degraded by photochemical processes, after evaporation or exposure to air.
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.
