Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 results of the chemical safety assessment do not indicate the need to investigate further the toxicity to sediment organisms
Key value for chemical safety assessment
Additional information
No experimental data concerning the toxicity of 2,3-dihydroxypropyl laurate (CAS No. 142-18-7) to sediment organisms are available. According to the standard requirements set in Regulation (EC) No. 1907/2006, Annexes VII, VIII and IX information regarding the effects of the substance on sediment organisms does not need to be presented at this tonnage band (100-1000 t/y).
2,3-dihydroxypropyl laurate is readily biodegradable. According to the Guidance on information requirements and chemical safety assessment, Chapter R.7b, readily biodegradable substances can be expected to undergo rapid and ultimate degradation in most environments, including biological Sewage Treatment Plants (STPs) (ECHA, 2008). Therefore, after passing through conventional STPs, only low concentrations of these substances are likely to be (if at all)released into the environment, and be available to sediment organisms.
The Guidance on information requirements and chemical safety assessment, R.7b (ECHA, 2008) states that in general, substances with log Kow or log Koc ≤ 3, are not likely to be adsorbed to sediment. 2,3-dihydroxypropyl laurate has a log Pow value of 3.29 but its log Koc values range from 1.5-2.1. Therefore, its adsorption potential to sediment particles is expected to be low and the assessment of the toxicity profile in the aquatic environment is covered adequately with pelagic tests. According to the Integrated Testing Strategy (ITS) for toxicity to sediment organisms (present in the above mentioned Guidance) no testing is necessary if the substance is not highly adsorptive or binding behavior to sediment particles is not expected. As 2,3-dihydroxypropyl laurate has a low adsorption potential, further testing on sediment organisms is not deemed necessary.
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.
