Name:
Unnamed
Type:
Constituent
Details on test material:
A c. 700 g sample of the test substance was received from the sponsor on
September 19, 1988. It consisted of a fine, white powder, designated:
“AF-366”. Just prior to application, the test substance was mixed with
water in a ratio of 1:1, by weight.

Test animals

Species:
rabbit
Strain:
New Zealand White
Details on test animals or test system and environmental conditions:
Healthy male, young adult, New Zealand White albino rabbits, obtained from
ENKI—Konijnenfarm, Someren, the Netherlands, were used as experimental
animals. The body weight range was 2571—3108 g. The animals were
identified by earmarking, and subsequently housed individually in
suspended, galvanized cages, fitted with a wire—mesh floor and front. The
cages were placed in a room, controlled for light (12 hours light/12 hours
dark cycle), temperature (18 ± 3°C), ventilation (c. 10 air changes/hour),
and relative humidity (at least 40%) throughout the test period.
A standard laboratory rabbit diet and tap water were provided ad libitum.
