Applicant's summary and conclusion
- Interpretation of results:
- irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on the study results, the test material Farmin TH is considered to be irritating to skin.
- Executive summary:
In an OECD TG 404 study the test substance Farmin TH (hydrogenated tallow alkyl amine), a white solid (pH = 9.93, purity 95%), was applied semi-occlusively for 4 hours to the shaved skin of three New Zealand White Rabbits. 0.5 g of the test substance, wetted with water, were applied on 2.5 cm2surgical gauze and applied to the shaved backs of the rabbits. Average scores for erythema were 2.0 (24 hours), 2.0 (48 hours) and 2.0 (72 hours). Scores for oedema were 1.3, 0.7 and 1.3 for the same time points. Whereas oedema reactions were reversible within 72 hours, erythema were still present after 7 days and reversed within 14 days.
The degree of skin irritation caused by the substance was determined after it was applied to shaved rabbit skin, under semi-occlusive patch, and left for 4 hours. The reaction on the test zone was evaluated approximately 30 -60 minutes and 24, 48 and 72 hours after the end of the exposure period. Additional observations were carried out after 7 and days to check the reversibility of the observed reactions. The substance is considered IRIITANT to the skin and it will have to be labelled with the notation of risk R38.
