Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Additional information:
In accordance with the CLP criteria, skin sensitizer is defined as “a substance that will lead to an allergic response following skin contact”. To be classified as a skin sensitiser (Category 1) there must be evidence of chemicals’s sensitizing effects observed in substantial number of people.
No data on skin sensitisation of trichloroethylene in experimental animals and only few cases in humans were reported. In addition, the QSAR modelling does not suggest active sensitisation properties of trichloroethylene. Therefore, it is not possible to classify trichloroethylene as a Skin Sensitiser.
Respiratory sensitisation
Endpoint conclusion
- Additional information:
In accordance with the CLP criteria, respiratory sensitizer is defined as “a substance that will lead to hypersensitivity of the airways following inhalation of the substance”. Generally, a substance is classified as respiratory sensitizer if there is evidence in humans that the substance can lead to specific respiratory hypersensitivity and/or if there are positive results from an appropriate animal test.
Currently, no recognized animal models for the testing of respiratory hypersensitivity are available.
Therefore, evidence that a substance can induce specific respiratory hypersensitivity will normally be based on human experience. However, no hypersensitivity reactions associated with exposure to trichloroethylene were reported in humans.
In conclusion, based on the respiratory sensitization data summarized here and taking into account that there have been no reports of respiratory sensitization caused trichloroethylene, it is not considered to be a respiratory sensitizer.
Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
