CAS number: 142-18-7
The results of the chemical safety assessment do not indicate the need to investigate further the toxicity to sediment organisms
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.
