Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
Justification for classification or non-classification
Skin Irritation
The ECHA Guidance on the application of the CLP Criteria set out that normally, the recommendations for classification according to GHS criteria based on the results of an in vitro test are mentioned in the corresponding OECD test guideline. According to the OECD Guideline 439 the cut-off values for the prediction of irritation are:
- The test chemical is considered to be irritant to skin in accordance with UN GHS Category 2 if the tissue viability after exposure and post-treatment incubation is less than or equal (≤) to 50 %.
- The test chemical may be considered as non-irritant to skin in accordance with UN GHS No Category if the tissue viability after exposure and post-treatment incubation is more than (>) 50 %.
The test item showed a value of the relative absorbance (75 %) above the threshold for irritation potential set out in the OECD guideline, therefore the substance is considered as NOT IRRITANT
Eye Irritation
The ECHA Guidance on the application of the CLP Criteria set out that a substance can be considered as causing serious eye damage (Category 1) based on positive results in the BCOP test, and a negative results from the BCOP test methods can be used for classification purposes.
According to the OECD Guideline 437 (Bovine Corneal Opacity and Permeability Test Method for Identifying Ocular Corrosives and Severe Irritants),the IVIS cut-off values for identifying test chemicals as inducing serious eye damage (UN GHS Category 1) and test chemicals not requiring classification for eye irritation or serious eye damage (UN GHS No Category) are:
- IVIS ≤ 3 – No Classification (UN GHS)
- IVIS > 3; ≤ 55 – No prediction can be made on the non classification
- IVIS > 55 – Category 1 (UN GHS)
The test item showed a value of in vitro irritancy score (IVIS ) of 32.68, therefore in the range of no prediction ( 3 > IVIS ≤ 55 ). Using a conservative approach, the test substance has been classified as Irritant to eyes Category 2, according to the CLP Regulation n. 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).
