SCORING SYSTEM:
Dermal responses were evaluated according to the scheme devised by DRAIZE JH (1959) Dermal Toxicity. Appraisal of the Safety of Chemicals in Foods, Drugs and Cosmetics, p46-59 (see below). For each rabbit and at each exposure time, the score is the mean of the readings made on the two test sites.

- Irritant / corrosive response data:
- After 3 minutes of exposure, moderate to severe erythema was noted in all animals at the 24, 48 and 72-hour observations. On day 7, glossy skin
with areas of flaking and dryness was observed. These adverse reactions reversed within 14 days. Moderate to severe oedema was noted in all
animals at the 24, 48 and 72-hour readings but cleared at day 7.
After 1-hour of exposure, eschar was noted in all animals at the 24, 48 and 72-hour readings. The eschar was surrounded by blanching and well-
defined or moderate erythema extending up to 4cm beyond the sites. Scattered punctate eschar also surrounded 2 of the treated sites. On day 7,
scabbing was noted over a large area of the treated sites in all animals. Flaking, dry, straw-coloured skin ( possible hyperkeratinisation) surrounded
the skin sites. On day 14, scar tissue considered to be indicative of corrosion and desquamation was noted in all animals. No fur growth was noted.
In all animals, moderate to severe oedema which extended ventrally was noted at the 24, 48 and 72-hour readings. No oedema was noted on days 7
and 14.

Applicant's summary and conclusion
- Interpretation of results:
- corrosive
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Corrosive effects were noted in all the 3 tested animals after a 1-hour exposure period to the test material. According to the criteria laid down in Council Directive 67/548/EEC (and subsequent adaptations) on the approximation of the laws, regulations and administrative provisions relating to classification, packaging and labelling of dangerous substances, the test material is classified Corrosive with the symbol C and the risk phrase R34
" Cause burns". - Executive summary:
Materials and methods
According to OECD 404 (1981), 3 rabbits were exposed to 0.5 ml of Amine, N- tallow alkyltrimethylenedi-. 24 hours before treatment the dorsal fur was shaved with electric clippers exposing approximately 2.5 cm x 2.5 cm of skin. Prior to test substance administration the animals where physically examined and if the shaved area of the skin was normal. 0.5 ml of test substance was applied to one flank using a gauze patch held in place by a non-irrtating semi-occlusive dressing and a restraining bandage. The animals were exposed for 3 minutes and after this period the dressing was removed and the skin was decontaminated by gentle swabbing with cotton wool soaked in 3% (v/v) aqueous acetic acid followed by distilled water. As no corrosive effects were observed after this exposure period, the same animals were exposed to the test material for one hour.
Results and discussion
After 3 minutes of exposure, moderate to severe erythema was noted in all animals at the 24, 48 and 72-hour observations. On day 7, glossy skin with areas of flaking and dryness was observed. These adverse reactions reversed within 14 days. Moderate to severe oedema was noted in all animals at the 24, 48 and 72-hour readings but cleared at day 7.
After 1-hour of exposure, eschar was noted in all animals at the 24, 48 and 72-hour readings. The eschar was surrounded by blanching and well-defined or moderate erythema extending up to 4cm beyond the sites. Scattered punctate eschar also surrounded 2 of the treated sites. On day 7, scabbing was noted over a large area of the treated sites in all animals. Flaking, dry, straw-coloured skin ( possible hyperkeratinisation) surrounded the skin sites. On day 14, scar tissue considered to be indicative of corrosion and desquamation was noted in all animals. No fur growth was noted.
In all animals, moderate to severe oedema which extended ventrally was noted at the 24, 48 and 72-hour readings. No oedema was noted on days 7 and 14.
Conclusion
Amine, N- tallow alkyltrimethylenedi- resulted in corrosive effects when applied to the intact rabbit skin for 1 hour
