Skin irritation / corrosion
Administrative data
- Endpoint:
- skin irritation: in vivo
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- July 1973
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Test was conducted according to methods similar to OECD 402 (limit test) and was performed pre-GLP. A concise description of the protocol is available and results are acceptable as basic data. .
Cross-reference
- Reason / purpose for cross-reference:
- read-across: supporting information
Reference
- Endpoint:
- skin irritation: in vivo
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Test was conducted according to methods similar to OECD 402 (limit test) and was performed pre-GLP. A concise description of the protocol is available and results are acceptable as basic data. Furthermore, due to the read-across purpose it was given a Klimisch 2 rating, in accordance with the ECHA Practical guide #6 on the reporting of read-across in IUCLID. The justification for read across is provided in the attached background material of the chapter summary.
- Justification for type of information:
- Three in vivo skin irritation studies with 3 different NCSs showed that these could be considered irritating, while the study with orange oil did not result in skin irritation. D-Limonene is also known to be irritating. As D-limonene is present in all NCSs of this group at levels higher than the 20% threshold mentioned in the classification and labelling directive (1999/45/EC, DPD and 1272/2008/EC, CLP and as three studies showed evidence of skin irritation, these results are read across to the other NCSs and the whole group is considered irritating to the skin and classified as R38 or H315.
