Test material
- Reference substance name:
- Diamino Trimethylphenylindane
- IUPAC Name:
- Diamino Trimethylphenylindane
- Test material form:
- solid: particulate/powder
- Details on test material:
- Purity:
97.6% (49.9% 6-4’ isomer, 47.7 5-4’ isomer; per Protocol)
Constituent 1
Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- Young albino rabbits of the New Zealand strain were used to evaluate
the eye i r r i t a t i n g properties of the test material. The test method was patterned
after that of Draize et_ a!. *
The test material was instilled into the conjunctival sac of the right
eye of each rabbit according to the treatment procedure presented in Table I.
The left eye of each animal served as a control.
