Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 404 (Acute Dermal Irritation / Corrosion)
- Version / remarks:
- 2017
- Deviations:
- yes
- Remarks:
- See below
- Principles of method if other than guideline:
- Deviations:
- Six times points of humidity deviated with the highest value measured being 73%. Deviations were very short time periods. This does not affect the quality and integrity of the study.
- At 24 and 48h, the observation of one of the animals deviated by about 4h. Because no dermal irritant symptoms were seen, this deviation was considered not to affect the quality and integrity of the study. - GLP compliance:
- yes (incl. QA statement)
- Remarks:
- 2016-05-30

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The Reaction mass of TFSK/TFAK is not iritating to the skin.
- Executive summary:
In an in vivo skin irritancy study following OECD TG 404 and under GLP conditions, three rabbits were dosed with 0.5 mL of the test substance. No mortality or systemic toxicity was observed. All erythema and edema scores were equal to 0. Based on the outcome of this study, it can be concluded that the test substance is not classified as corrosive or irritant to the skin.
