Cutaneous reactions: Slight to well-defined erythema and slight oedema were observed at the treatment sites of all animals. Recovery was generally complete by Day 6 with the exception of one male rat which showed slight oedema until Day 9.
On Day 6 all the rats developed small, slightly raised erythematous areas at the dose site. Signs of recovery from this were indicated on Day 9 when small focal scab formations were observed. These persisted until Day 15 in all rats except two females which had completely recovered by Day 14.

- Under the test conditions, Petrepar-147 is not classified according to the criteria of Annex VI to the Directive 67/548/EEC and CLP Regulation 1272/2008.
- Executive summary:
This data is being read across from the source study that tested Hydrocarbons, C14-C17 n-alkanes, <2% aromatics based on analogue read across.
Petrepar P-147 was tested for acute dermal toxicity in HC/CFY (remote Sprague-Dawley) rats in a limit dose assay according to OECD guideline N°402. The test substance, a liquid, was administered undiluted as supplied. A 10% total body surface of hair was removed from the dorso-lumbar region with clippers in every animal. The assay was conducted on a group of 10 rats (5 males, 5 females) with a dose of 2000 mg/kg b.w. administered by spreading in a single dermal dose (maximum dose volume of 2.6 mL/kg b.w). After test substance application an occlusive patch was held in place for 24 hours. Skin was washed with water at the end of the 24-hour exposure period.
Examinations for mortality, clinical signs and body weight gain were performed during the 14-day observation period. All surviving animals were necropsied at the end of the observation period.
No deaths and clinical signs occurred during the observation period.Body weight gain was not affected by treatment. At necropsy, macroscopic examination of main organs showed no abnormalities.
Slight to well-defined and slight oedema was observed at the site of treatment in all animals. Reversibility was generally observed by day 6 with the exception of one animal showing slight oedema until Day 9. All rats developed small, slightly raised erythematous areas at the dose site on the day 6. Then, small focal scab formations persisted from day 9 to day 15 in all rats except two females which had recovered by day 14. Two small areas of necrosis were observed at the treatment site on two males on day 2 but not on day 6 and day 9, respectively.
As the acute dermal LD50 was greater than 2000 mg/kg b.w. under the test conditions, Petrepar P-147 is not classified according to the criteria of Annex VI to Directive 67/548/EEC and CLP Regulation 1272/2008.
