Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Phototransformation in air
Parent compound palmitoyl chloride and hydrolysis product palmitic acid: After evaporation or exposure to air, the substance will be slowly degraded by photochemical processes.
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
Parent compound palmitoyl chloride: In contact with water the substance hydrolyses rapidly (t1/2 < 5 min).
Hydrolysis product palmitic acid: Palmitic acid is readily biodegradable.
Additional information
Palmitoyl chloride hydrolyses very quickly to palmitic acid (CAS 57 -10 -3) and HCl (CAS 7647 -01 -0) (t1/2 < 5 min, see IUCLID Ch. 5.1.2). Therefore, the assessment is mainly based on the hydrolysis product palmitic acid.
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.
