Any other information on results incl. tables

Groups of 5 male and 5 female Wistar rats received a single dermal dose of 2000 mg/kg bw of C.I. Direct Blue 264 applied semiocclusively for 24 hours.

A dose of 2000 mg/kg bw was tolerated by male and female rats without mortalities, toxicologically relevant clinical signs, toxicological effects on weight development and gross pathological findings.
