Description of key information
Skin:
In two studies on skin irritation/corrosion (OECD 431, 439), a skin corrosive potential of the test substance was determined (BASF SE, 2016).
In a study on skin irritation/corrosion according to OECD 435 using the Corrositex® test system, no irritating/corrosive potential of the test substance was observed (BASF SE, 2016).
Eye:
In an in vivo eye irritation study in rabbits similar to OECD 405, the test substance caused irriversible eye damage (BASF SE, 1979).

Additional information
Skin:
The objective of the studies was to assess the skin irritation and corrosion potential of (+)-3-Aminomethylpinan. Using the currently available methods a single in vitro assay is not sufficient to cover the full range of skin irritating/corrosion potential. Therefore, three in vitro assays were part of this in vitro skin irritation and corrosion test strategy: The Skin Corrosion Test (SCT, according to OECD Guideline 431), the Skin Irritation Test (SIT, according to OECD Guideline 439) and the in vitro membrane barrier method for skin corrosion (according to OECD Guideline 435).
The potential of (+)-3-Aminomethylpinan to cause dermal corrosion/irritation was assessed by a single topical application of 50 μL (corrosion test) or 30 μL (irritation test) of the undiluted test substance to a reconstructed three dimensional human epidermis model (EpiDerm™).
For the corrosion test two EpiDerm™ tissues were incubated with the test substance for 3 minutes and 1 hour, each. The irritation test was performed with three EpiDerm™ tissues, which were incubated with the test substance for 1 hour followed by a 42-hours post-incubation period.
Tissue destruction was determined by measuring the metabolic activity of the tissue after exposure/post-incubation using a colorimetric test. The reduction of mitochondrial dehydrogenase activity, measured by reduced formazan production after incubation with a tetrazolium salt (MTT) was chosen as endpoint. The formazan production of the test-substance treated epidermal tissues is compared to that of negative control tissues. The quotient of the values indicates the relative tissue viability.
The following results were obtained in the EpiDerm™ skin corrosion/irritation test:
The test substance is able to reduce MTT directly. Therefore an additional MTT reduction control KC (freeze-killed control tissues) was introduced. In both tests high KC-values for direct MTT-reduction of the test substance were determined. Thus the final mean viabilities of the test-substance treated tissues are given after KC correction.
Results of the corrosion test:
The mean viability of the test-substance treated tissues determined after an exposure period of 3 minutes was 0 %, and it was 13 % after an exposure period of 1 hour.
Results of the irritation test:
The mean viability of the test-substance treated tissues determined after an exposure period of 1 hour with about 42 hours post-incubation was 0 %.
The KC-values for direct MTT-reduction of the test substance are out of the acceptance range. However, the evaluation is considered to be valid, due to the unambiguous result of the 3 minutes exposure without correction of the KC-value for MTT reduction.
Based on the observed results and applying the evaluation criteria it was concluded, that (+)-3-Aminomethylpinan shows a skin corrosive potential in the EpiDerm™ in vitro skin irritation and corrosion test strategy under the test conditions chosen.
In contrast, in the the in vitro membrane barrier method for skin corrosion using the Corrositex® test system (BASF SE, 2016), the test substance showed no corrosive potential after application of 500 µL test substance onto the test matrices and an incubation of > 60 min. According to the OECD Guideline 435 liquids with an pH in the range of 4.5 to 8.5 often do not qualify for this test. This could be the reason for the different outcome since the test substance has a pH of ~7.
In conclusion, taking into account the positive results of the in vitro skin irritation (OECD Guideline 439) and in vitro skin corrosion (OECD Guideline 431) assays, a classification into Category 1B is justified.
Eye:
In a primary eye irritation study, 0.1 mL of (+)-3-aminomethylpinan in olive oil was instilled into one conjunctival sac of 6 adult New Zealand white rabbits (2.3 - 2.8 kg) for 24 hours (BASF SE, 1979). The eyes were not washed thereafter. Animals were then observed for 8 days. Irritation was scored by the method of Draize.
Very severe, irreversible damages to the eyes were observed (mean scores of all observed functional units were at maximum). In this study, (+)-3-aminomethylpinan was corrosive to the eye based on the scores (mean of 24, 48, and 72 h).
Justification for classification or non-classification
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008.
Eye and skin corrosive properties were documented. As a result the substance should be considered to be classified as eye irritant (category 1, H318) and skin corrosive (subcategory 1B, H314) under Regulation (EC) No 1272/2008, as amended for the tenth time in Regulation (EU) No 2017/776.
