Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

PBT status:
the substance is not PBT / vPvB

The PBT Assessment is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2017).


Persistence Assessment

Chloroethane is not readily biodegradable according to OECD criteria. No biodegradation was observed in a closed bottle test. Chloroethane is a gaseous substance, which will be mainly present in air. Abiotic degradation by hydrolysis is not expected to be a relevant degradation process; estimated half-lives range between 38 days and 2.6 years. The available data on the atmospheric half-life indicate a range between 26.5 and 66.8 days

Based on the information listed above chloroethane needs to be considered as potentially P/vP


Bioaccumulation Assessment

Bioaccumulation in organisms is not expected for substances with a log Kow ≤ 4.5.

Based on the partition coefficient of chloroethane (log Pow 1.43, Hansch, 1995), the potential for bioaccumulation is considered to be low. This is supported by low BCF values <2000 L/kg (BCFBAF v3.01, Arnot-Gobas, including biotransformation, upper trophic). Based on the available information, the substance does not meet the B or vB criteria.


Toxicity Assessment

The substance is classified as toxic to reproduction (category 1B). The substance is defined as T.


Conclusions on PBT or vPvB properties:
The substance does not fulfil the PBT and vPvB criteria.
