Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Scoring of irritation was performed using the method of Draize. The test material was classified as not irritating.
- Executive summary:
Read across justification
The physical and chemical properties of foots oils are comparable to the other lubricant base oil intermediate streams from which they are derived. Hence their health effects are also similar to those of other lubricant base oils, and the conclusions of the hazard assessment for other lubricant base oils also apply to foots oils.
In a eye irritation study, nine New Zealand White rabbits were exposed to 0.1 mL of hydrotreated light naphthenic distillate in one eye. The other eye served as the no-treatment control. After instillation of the test material the upper and lower lids of the test animals were held together for one second. Twenty to thirty seconds following instillation the eyes of three of the six test animals were flushed for one minute with lukewarm water. The eyes of the remaining test animals were unflushed. Observation for ocular lesions were made in all animals at 1, 24, 48, and 72 hours and 7 days after treatment. Body weights were recorded immediately prior to application and upon study termination. Scoring of irritation was performed using the Draize technique. At study termination all animals were euthanized.
There was no pain response during instillation of the test material and no corneal or iridial irritation was seen during the study. Any irritation that occurred had cleared by 48 hours. In this study the study material was considered not irritating to the eye.
This study received a Klimisch score of 1 and is classified as reliable without restriction because it was conducted according to OECD guideline 405.
