Details on test material:
TEPIC-G (TGIC) technical grade

Test animals

Species:
rat
Strain:
Sprague-Dawley
Sex:
male/female
Details on test animals or test system and environmental conditions:
Sprague-Dawley rats (CFY strain, 200-247 gm)
Animals were acclimatized for at least 5 days

Administration / exposure

Type of coverage:
semiocclusive
Vehicle:
arachis oil
Details on dermal exposure:
shaved om the back and the flanks generating a nacked area of 5 x 4 cm (24 hours before treatment). The appropriate amount of dry TGIC was applied to the hair-free skin area which was previously moistened with arachis oil, and surgical gauze was applied to gether with an Elastoplast to generate a semi-occlusive bandage.
Duration of exposure:
Animals were then caged individually in PVC cages, and after 24 hours the bandage was removed and the skin washed with water, then the animals were housed bysex as a group of five.
Doses:
2000 mg/kg bw (single dose)
No. of animals per sex per dose:
5 males & 5 females
Control animals:
not required
Details on study design:
A group of 5 male and 5 female Sprague-Dawley rats (CFY strain, 200-247 gm) was shaved om the back and the flanks generating a nacked area of 5 x 4 cm (24 hours before treatment). The appropriate amount of dry TGIC was applied to the hair-free skin area which was previously moistened with arachis oil, and surgical gauze was applied to gether with an Elastoplast to generate a semi-occlusive bandage. Animals were then caged individually in PVC cages, and after 24 hours the bandage was removed and the skin washed with water, then the animals were housed bysex as a group of five. All animals were observed 1 and 4 hours after dosing and therafter daily once for 14 days.
