Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.1, the substance is not officially classified.

In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.2, the substance is not officially classified.

 

Self-classification

Aquatic compartment

Following DSD/DPD, the substance is not to be classified as dangerous for the aquatic environment.

Rationale: The acute toxicity to aquatic organisms (LL/EL50) is between10 and100 mg/L (loading), but the substance is readily biodegradable.

 

Following GHS, the substance is not to be classified as hazardous to the aquatic environment.

Rationale: Chronic data are available only for algae, therefore classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data: Chronic data are available only for algae (ErL10 = 28.5 mg/L; loading) indicating that the substance does not present a long-term hazard according to the categories outlined in Table 4.1.0(b) (ii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for rapidly degradable substances.

- Acute toxicity data: The acute toxicity to aquatic organisms (LL/EL50) is between10 and 100 mg/L (loading), but the substance is rapidly biodegradable. The log Kow of some of the acyl halides is indeed ≥ 4, but based on weight of evidence using reliable QSAR data and including experimental data for the major hydrolysis product lauric acid (CAS 143 -07 -7), the BCF is expected to be clearly below 500.

 

Atmospheric compartment

The test substance is not in Annex I of Regulation (EC) 2037/2000 on substances that deplete the ozone layer.

The test substance does not belong to the green house gases listed in P Forster, PV Ramaswamy et al. Changes in Atmospheric Constituents and in Radiative Forcing. In: Climate Change 2007: The Physical Basis. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on climate Change.
