Description of key information
In a primary skin and eye irritation study, no skin or eye irritating effects were observed in six Himalayan rabbits. This was further supported by two in vitro tests, concluding that the test substance is non corrosive to skin and eyes (BASF SE, 1999).

Additional information
Skin irritation
In a primary skin irritation test according to OECD guideline 404 and EU method B.4, 0.5 g test substance (moistened with aqua bidest.) was administered to the intact skin of three male Himalayan rabbits for 4 hours under semi-occlusive dressing (BASF SE, 18H0464/982240, 1999). Residual test substance was washed off with Lutrol and Lutrol/water (1:1) after the exposure period. Animals were then observed for 72 hours. Scoring was performed according to Draize et al. (1965). Skin readings were performed 1, 24, 48 and 72 hours after end of exposure period. A check for any dead or moribund animal was made twice each workday and once on Saturdays, Sundays and on public holidays.
Only one animal showed very slight erythema at the 24 and 48 hour reading. Erythema was fully reversible within 72 hours after exposure. No edema was observed.
Under the test conditions chosen and considering the described transient and mild findings, the test substance does not give indication of an irritant property to the intact rabbit skin.
This result is further supported by an in vitro screening assay using the EpiDerm Corrosivity Test kit (BASF SE, 61H0464/982205, 1999). Two trials were performed. The percentage of viability of the test substance was 85 and 89 % percent, respectively, underlining that the test substance is not corrosive to the skin.
Eye irritation
In a primary eye irritation test according to OECD guideline 405 and EU method B.5, 0.1 mL of the test substance was installed into the conjunctival sac of the right eye of three young adult Himalayan rabbits (males) for 24 hours (BASF SE, 11H0464/982241, 1999). Eyes were washed with tap water. Animals were then observed for 14 days. Irritation was scored by the method of Draize et al (1965).
The average score (24 to 72 hours) for irritation was calculated to be 0.8 for corneal opacity, 0.2 for iris, 1.8 for conjunctival redness and 0.4 for chemosis. One animal exhibited suppuration and loss of corneal tissue 48 and 72 hours after application. These findings as well as other observed symptoms were fully reversible in all animals within 14 days after application.
According to the findings in this test, the test substance is considered slightly irritating. But the results do not fulfil the classification criteria according to CLP.
This result is further supported by an in vitro Hen's egg test on chorioallantoic membrane (HET-CAM) (BASF SE, 60H0464/982206, 1999). Three eggs were treated with the test substance and no hemorrhages, lysis and coagulation was seen up to 300 s after application of the test substance. An irritation index of 0 was determined. The test substance is therefore regarded as non-corrosive the eyes.
Justification for selection of skin irritation / corrosion endpoint:
GLP and guideline compliant study.
Justification for selection of eye irritation endpoint:
GLP and guideline compliant study.
Justification for classification or non-classification
The available experimental test data are reliable and suitable for classification purposes. As a result the substance does not need to be classified and labelled for skin and eye irritation under Regulation (EC) No 1272/2008, as amended for the seventh time in Regulation (EU) No 2015/1221.
