Justification for classification or non-classification
In the CLP Regulation (EC 1272/2008), in the section 3.4 Respiratory or skin sensitisation, a skin sensitizer is defined as a substance that will lead to an allergic response following skin contact.
A substance shall be classified as skin sensitisers (Category 1) where data are not sufficient for sub-categorisation (1A and 1B) in accordance with the following criteria:
(a) if there is evidence in humans that the substance can lead to sensitisation by skin contact in a substantial number of persons; or
(b) if there are positive results from an appropriate animal test (according to 3.4.2.2.4.1).
If, in order to evaluate skin sensitisation potential, a Guinea pig maximisation test is performed, a substance is classified as skin sensitiser when the response of at least 30 % responding at ≤ 0,1 % intradermal induction dose or at least 60 % responding at > 0,1 % to ≤ 1 % intradermal induction dose.
Under the test conditions the substance resulted in a sensitisation rate of 0 % after intra-cutaneous and epi-cutaneous application to the guinea pig. Therefore, according to the CLP Regulation (EC 1272/2008), the substance is not classified as skin sensitiser.
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.
