Reference
Descriptive scores of the raw data have been converted to Draize numerical scores.
At BASF’s Department of Toxicology, acute toxicity testing was performed according to published methods, which were adapted and standardized for the specific needs of the company, well before Test Guidelines for these methods were established by the OECD beginning 1982. These methods were comparable to the Union Carbide (now a DOW company) range finding toxicity data which have been published in the early toxicological literature (1944-1949). The results of these studies were reported until the early 1980s in summary reports called „Ergebnis der gewerbetoxikologischen Vorprüfung“ or „Toxikologische Grundprüfung“, which do not present details of the methods used, but focus on a summary presentation of the results.

Additional information
Skin irritation:
Skin irritation was tested using a standard method (BASF AG, 1971). The study meets scientific standards with acceptable restrictions (limited documentation). Two New Zealand White rabbits were treated for1, 5, 15 min and 20 h at the back using a gaze pad (2.5 cm²) and for 20 h in the inner surface of the ear with a cotton ball.The post exposure period was 8 days.Both treated animals showed weak (1 and 5 min) to severe (20 hours) necrosis, with an increasing area of necrosis during the observation period (treatment site back). Severe necrosis and at the end of the observation period and on day 8 post application mumifaction of the area of expsoure were observed at the treatment site ear.
In a second study ( Bayer AG, 1977) the test item was tested using as well a standard method. The study meets scientific standards with acceptable restrictions (limited documentation). Two New Zealand White rabbits were treated for 1 and 4 hours. The inner surface of the ear was treated with 500 µL of the undiluted test substance and occlusively covered. After the exposure time the test substance was rinsed with water and soap/plant oil. The post exposure period was 7 days. After the exposure period of 1 or 4 hours intense reddening and moderate swelling of the treated ear region was observed. Also severe corrosion was reported in both animals.
Eye irritation:
Eye irritation was tested using a standard method (BASF AG, 1971). The study meets scientific standards with acceptable restrictions (limited documentation). 0.05 mL of the test substance was applied to the conjunctival sac of each one eye of 2 rabbits (Vienna White). Treatment was followed by an observation period of 8 days. Both treated animals showed corrosion of the eye after 1 h, additionally edema after 24 h and purulence after 8 d. No irritant or corrosive response was observed in the control eyes. Thus the test item was highly corrosive to the rabbit eye.
In a second study (Bayer AG, 1977) the test item was tested using as well a standard method. The study meets scientific standards with acceptable restrictions (limited documentation). 100 µL of the test substance was applied to the conjunctival sac of each one eye of 2 rabbits (New Zealand White), without washing and an observation period of 7 days. The conjunctiva of the treated animals was completely clouded and weak to severe reddening and swelling of the cornea could be observed at the end of the observation period. Thus the test item was highly corrosive to the rabbit eye.
