- PRE-EXPERIMENTAL PROCEDURE
The skin of the back of the animals was clipped 24 h before treatment and examined for potential lesions. Since the animals showed no evidence of abnormalities, it was allocated to the test.
ADMINISTRATION OF THE TEST ARTICLE
The test article was used as supplied by the sponsor. One of the animals (rabbit no. 1) was treated with 0.5 ml of the liquid test article, which was applied to the left side of the back, the untreated right side served as control. The test article was applied to a gauze patch and then applied to the skin. The closed patch exposure was effected by means of a semiocclusive bandage using Ypsiplast® (Holthaus Medical, Remscheid-Lüttringhausen), non-irritating tape Elastoplast® (Beiersdorf AG, Hamburg) and Stülpa® (P. Hartmann AG, Heidenheim-Brenz), which enveloped the whole of the animal's trunk. Exposure duration was 4 h. Since there were only a moderate response to the application of the test article, the further two animals were treated subsequently in the same manner.

In a primary dermal irritation study according to OECD Guideline 404, 17 July 1992 and EU Method B.4, 29 December 1992, three White New Zealand rabbits were semi-occlusive dermaly exposed to 0.5 mL of Bis(2-ethylhexyl) carbonate (approx. 100 % a.i.) for 4 hours. Animals then were observed for 8 days. Irritation was scored by the method of Draize as stipulated by OECD Guideline 404.
Slight to well-defined erythema was observed in all animals 1 h after patch removal following the 4-hour exposure and was still apparent, unchanging or increasing in degree, up to day 4 or 5 after exposure. The score 3 was observed in one animal 24 and 48 h and in one animal 72 h after exposure. Subsequently, a decreased degree of erythema was observed until the reversibility on days 7 and 8 after exposure. Very slight to slight oedema was seen in the animals between 1 h and day 5 after exposure. Additionally, slight eschar formation was observed in one animal on days 4 and 5 after exposure. The observed findings were fully reversible within 8 days after patch removal.
Mean values of skin reactions at 24, 48 and 72 h were ≥ 2.3 ≤ 4.0 for erythema/eschar in 2 of 3 animals.
The test substance Bis(2-ethylhexyl) carbonate is considered to be a skin irritant Category 2 according to CLP, EU GHS (Regulation (EC) No 1272/2008).

The animal was treated with 0.1 mL of the liquid test article, which was introduced into the conjunctival sac of the right eye after gently pulling the lower lid away from the eyeball. The lid was then gently held together for about 1 sec in order to limit loss of the test article. The untreated left eye served as control. Since there was no remarkable response to the instillation of the test article, the further two animals were treated subsequently in the same manner.

Additional information
Skin irritation
In a primary dermal irritation study according to OECD Guideline 404, 17 July 1992 and EU Method B.4, 29 December 1992, three White New Zealand rabbits were semi-occlusive dermaly exposed to 0.5 mL of Bis(2-ethylhexyl) carbonate (approx. 100 % a.i.) for 4 hours. Animals then were observed for 8 days. Irritation was scored by the method of Draize as stipulated by OECD Guideline 404.
Slight to well-defined erythema was observed in all animals 1 h after patch removal following the 4-hour exposure and was still apparent, unchanging or increasing in degree, up to day 4 or 5 after exposure. The score 3 was observed in one animal 24 and 48 h and in one animal 72 h after exposure. Subsequently, a decreased degree of erythema was observed until the reversibility on days 7 and 8 after exposure. Very slight to slight oedema was seen in the animals between 1 h and day 5 after exposure. Additionally, slight eschar formation was observed in one animal on days 4 and 5 after exposure. The observed findings were fully reversible within 8 days after patch removal.
Mean values of skin reactions at 24, 48 and 72 h were ≥ 2.3 ≤ 4.0 for erythema/eschar in 2 of 3 animals.
The test substance Bis(2-ethylhexyl) carbonate is considered to be a skin irritant Category 2 according to CLP, EU GHS (Regulation (EC) No 1272/2008).
Eye irritation
In a primary eye irritation study according to OECD Guideline 405, 17 July 1992 and EU Method B.5, 29 December 1992, 0.1 ml of Bis(2-ethylhexyl) carbonate (approx. 100 % a.i.) was instilled into the conjunctival sac of three White New Zealand rabbits. The eyes were not rinsed after substance application. Animals then were observed for 4 days. Irritation was scored by the method of Draize as stipulated by OECD Guideline 405.
Slight or moderate redness and slight swelling of the conjunctivae were observed in all animals 1 h after instillation. Redness, slight or moderate in degree, was still apparent 24 h after instillation in the three rabbits and up to 72 h after instillation in rabbit no. 3. No ocular findings were seen on day 4 of the study. The observed findings were fully reversible within 4 days in all animals.
Calculated mean scores following grading at 24, 48 and 72 hours after installation of the test material for effects on the conjunctiva are 0.33 for two animals and 1.33 for the third animals. Mean scores for effects on the cornea as well as for effects on the iris were 0.0 for all animals.
The test substance Bis(2-ethylhexyl) carbonate is considered to be neither a seriously eye damaging substance nor an eye irritant according to CLP, EU GHS (Regulation (EC) No 1272/2008).
Respiratory irritation
No data on the respiratory irritation are available.
There are no data gaps for the endpoint irritation/corrosion. No human information is available for this endpoint. However, there is no reason to believe that these results from laboratory animals would not be applicable to humans.
Justification for selection of skin irritation / corrosion endpoint:
study according to OECD and EU guidelines, no deviations, GLP
Justification for selection of eye irritation endpoint:
study according to OECD and EU guidelines, no deviations, GLP
Effects on skin irritation/corrosion: irritating
Justification for classification or non-classification
A classification of Bis(2-ethylhexyl) carbonate is not justified for eye damaging or eye irritating effects according to CLP, EU GHS (Regulation (EC) No 1272/2008) as well as the former European directive on classification and labelling Directive 67/548/EEC.
Classification of eye effects is based on diagnosis of cornea, iris and conjunctiva, calculated as mean scores following grading at 24, 48 and 72 hours after treatment, in consideration of reversibility. Results were taken from the key study on eye irritation,
performed according OECD Guideline 405 and EU Method B.5.
A classification of Bis(2-ethylhexyl) carbonate is justified for skin irritation according to CLP, EU GHS (Regulation (EC) No 1272/2008 as well as the former European directive on classification and labelling Directive 67/548/EEC. In a study performed according to OECD Guideline 404 and EU Method B.4 reversible irritation was observed. Mean scores of skin reactions at 24, 48 and 72 h were ≥ 2.3 ≤ 4.0 for erythema/eschar in 2 of 3 animals.Therefore, it is justified to classify Bis(2-ethylhexyl) carbonate as skin irritant Category 2 according to CLP, EU GHS (Regulation (EC) No 1272/2008) and with R38 according to the former European directive on classification and labeling Directive 67/548/EEC.
