Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
The skin sensitization potential of hydrocarbons, C7-C9, n-alkanes, isoalkanes, cyclics, was studied in a guinea pig maximization test (Magnusson/Kligman method) similar to OECD 406. Guinea pigs (10/sex in treated group and 5/sex in control group) were induced with 1% (w/v) of the test substance in corn oil as a 0.1 ml injection in the shaved shoulder region. Six to eight days later a topical induction of 50% (w/v) test material was applied under an occlusive dressing for 48 hrs. On Day 20-21 guinea pigs were challenged with 25% (w/v) test material applied to the shaved flank. Skin response was evaluated immediately after challenge, and 24 and 48 hours later. The test substance did not cause indication of skin sensitization in any guinea pig at any evaluation period after challenge (Shell Chemicals, 1977).
Migrated from Short description of key information:
The available data on the skin sensitisation potential of hydrocarbons, C7-C9, n-alkanes, isoalkanes, cyclics indicate that the substance is not a skin sensitiser.
Justification for classification or non-classification
The available data on the skin sensitisation potential of hydrocarbons C7-C9, n-alkanes, isoalkanes, cyclics are conclusive but not sufficient for classification.
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.
