Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritant) 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 irritation/corrosion hazard of the registered substance. The decision of classification as skin irritant was based on existing data on constituents (additivity principles): the registered substance has more than 10% of its constituents classified as Skin irritant Category 2 (Carvacrol, linalool, myrcene, 4 -terpinenol and alpha-pinene) and one constituent classified as skin corrosive 1B (H314) potentially < 5% (thymol) ; therefore, it should be classified as a skin irritant without further testing according to the rules for classification of mixtures of Regulation (EC) No 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
