Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Skin sensitisation

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:

No studies are available that report the sensitisation potential of chloroprene in experimental animals. There have been no reported cases of hypersensitivity associated with occupational exposures to chloroprene.


Migrated from Short description of key information:
No studies are available to determine sensitisation potential in animals. Human occupational exposure suggests that no cases of contact hypersensitivity have been attributed to exposure to chloroprene.

Respiratory sensitisation

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:

No studies are available that report the sensitisation potential of chloroprene in experimental animals. There have been no reported cases of hypersensitivity associated with occupational exposures to chloroprene.

Justification for classification or non-classification

Chloroprene is not classified as a sensitiser according to EU classification legislation.
