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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The hazard assessment is based on the data currently available. New studies with the registered substance and/or other member substances of the glycol esters category will be conducted in the future. The finalised studies will be included in the technical dossier as soon as they become available and the hazard assessment will be re-evaluated accordingly.
For further details, please refer to the category concept document attached to the category object (linked under IUCLID section 0.2) showing an overview of the strategy for all substances within the glycol esters category.

Octadecanoic acid, monoester with 1,2-propanediol (CAS 1323-39-3) and Palmitic acid, monoester with propane-1,2-diol (CAS 29013-28-3) is determined to be readily biodegradable. Due to the low water solubility, rapid environmental biodegradation and metabolisation via enzymatic hydrolysis of glycol esters, a relevant uptake and bioaccumulation in aquatic organisms is not expected. Hence, abiotic degradation is not a relevant pathway of Octadecanoic acid, monoester with 1,2-propanediol (CAS 1323-39-3) and Palmitic acid, monoester with propane-1,2-diol (CAS 29013-28-3).
Based on its physico-chemical properties such as low water solubility, low volatilization potential and high log Koc, sediment and soil are expected to be the main targets for environmental distribution of Octadecanoic acid, monoester with 1,2-propanediol (CAS 1323-39-3) and Palmitic acid, monoester with propane-1,2-diol (CAS 29013-28-3). However, due to its ready biodegradability, the substance will not persist in these compartments if exposure occurs.
For the assessment of Octadecanoic acid, monoester with 1,2-propanediol (CAS 1323-39-3) and Palmitic acid, monoester with propane-1,2-diol (CAS 29013-28-3) a read-across approach was chosen, based on data from similar fatty acid esters.
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.
