Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment

Acute toxicity: via oral route

Endpoint conclusion
Dose descriptor:
LD50
Value:
2 000 mg/kg bw

Additional information

Only one oral toxicity test was conducted with the reaction mass containing mainly 2-chloropropene. The resulting LD50 cut-off value was considered to exceed 2000 mg/kg body weight.

Justification for classification or non-classification

Oral toxicity:

According to the OECD 423 test guideline, the LD50 cut-off value was considered to exceed 2000 mg/kg body weight.

Based on these results, Reaction mass containing mainly 2-chloropropene does not have to be classified and has no obligatory labeling requirement for acute oral toxicity according to the DSD as well as to the CLP legislation.

Dermal toxicity:

As no data were available for this endpoint, the LD50 of the officially classified substances constituting the reaction mass were used. Therefore, the LD50 of 2-chloropropane (1100 mg/kg-default value) and of 3-chloropropene (398 mg/kg) were taken into account to calculate the classification. According to the CLP and DSD legislation criterias established for the mixtures, the reaction mass containing mainly 2-chloropropene shall not be classified.

Inhalation toxicity:

As no data were available for this endpoint, the LC50 of the officially classified substances constituting the reaction mass were used. Therefore, the LC50 of 2-chloropropane (11 mg/m3 -default value) and of 3-chloropropene (2.9 mg/m3) were taken into account to calculate the classification. According to the CLP and DSD legislation criterias established for the mixtures, the reaction mass containing mainly 2-chloropropene shall not be classified.
