Results and discussion

In vivo

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.

Any other information on results incl. tables

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.
