Remarks:
Criteria used for interpretation of results: other: CLP
Conclusions:
The dermal toxicity of hydrocarbons, C7-C9, n-alkanes, isoalkanes, cyclics was examined. Groups of two female and two male rats were exposed dermally to 1, 2, or 4 mL/kg of test substance. No animals died during the experiment. The dermal LD50 for rats is >= 4 mL/kg. The test substance is not classified as a dermal toxic under OECD GHS guidelines.
Executive summary:

This data is being read across from the source study that tested Hydrocarbon C7-C9, n-alkanes, isoalkanes, cyclics based on analogue read across.

The dermal toxicity of hydrocarbons, C7-C9, n-alkanes, isoalkanes, cyclics was examined. Groups of two female and two male rats were exposed dermally to 1, 2, or 4 mL/kg of test substance. No animals died during the experiment. The dermal LD50 for rats is >= 4 mL/kg. The test substance is not classified as a dermal toxic under OECD GHS guidelines.
