Applicant's summary and conclusion
- Interpretation of results:
- Category 1B (indication of skin sensitising potential) based on GHS criteria
- Executive summary:
The NCS is composed of several identified constituents and in that, it can be considered as a mixture according to the definition of the CLP Regulation. The decision logic for classification of mixtures from the ECHA Guidance on the Application of the CLP Criteria (2017) was used to determine the skin sensitising potential of the registered substance.
The registered substance has not been tested itself in appropriate in vitro or in vivo tests but some of its constituents are classified as skin sensitisers Cat. 1B (carvacrol, linalool, beta-caryophillene, alpha-pinene) and potentially present above the CLP generic concentration limit of 1% for category 1B that triggers classification of the mixture. Therefore, the registered substance is classified as a skin sensitiser Cat. 1B without further testing according to the Regulation (EC) No 1272/2008.
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).
