Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Control animals:
not specified
Details on study design:
- Duration of observation period following administration: 14 days
- Test conditions and method according to Smyth et al. (1962):
Penetration of rabbit skin was estimated by a technique closely akin to  the one-day cuff method of Draize et al. (1944) using groups of four male albino New Zealand rabbits weighing 2.5 to 3.5 kg. The fur was removed from the entire trunk by clipping, and the dose was retained beneath an  impervious plastic film. Dosages greater than 20 mL/kg bw could not be retained in contact with the skin. The animals were immobilized during the 24-hour contact period, after which the film was removed and the rabbits were caged for the subsequent 14-day observation period. The LD50 was calculated by the method of Thompson (1947).

Statistics:
The LD50 was calculated by the method of Thompson (1947).
