Remarks on result:
other: Skin sensitiser category 1
Interpretation of results:
Category 1 (skin sensitising) 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.1 and are all potentially present above the CLP generic concentration limit of 0.1% and 1% that triggers classification of the mixture. Therefore, the registered substance is classified as a skin sensitiser Cat. 1 without further testing according to the Regulation (EC) No 1272/2008.

Endpoint conclusion
Endpoint conclusion:
adverse effect observed (sensitising)
Additional information:

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 1 (Benzyl cinnamate, and Isoeuggenol) and are present above the CLP generic concentration limit of 1% that triggers classification of the mixture.

Therefore, the registered substance is classified as a skin sensitiser 1 without further testing according to the Regulation (EC) No 1272/2008.

Justification for classification or non-classification

Harmonized classification:

The registered substance has no harmonized classification according to the Regulation (EC) No. 1272/2008.

Self-classification:

Based on the typical composition provided by the Lead Registrant, the registered substance is classified as skin sensitiser: Skin Sens. 1, H317 (May cause an allergic skin reaction) according to the Regulation

(EC) No. 1272/2008 (CLP).

No information was available regarding respiratory sensitisation.
