- Irritant / corrosive response data:
- Reversibility of any observed effect: Changes not fully reversible within 3 days
- Other effects:
- Instillation of approximately 71 mg of ethylene deltenone (a
volume of appr. 0.1 ml) into one eye of three rabbits
resulted in effects on the iris and conjunctivae. iridic
irritation grade 1 was observed in two animals, 1 hour
after instillation only. The irritation of the conjunctivae
consisted of redness, chemosis and discharge and had
completely resolved within 48 hours in two animals and
within 72 hours in the third animal.
No corneal opacity was observed, and treatment of the eyes
with 2% fluorescein, 24 hours after test substance
instillation revealed no corneal epithelial damage in any
of the animals.
There was no evidence of ocular corrosion.
Remnants of the test substance were present in the eyes of
all animals on day 1.
No symptoms of systemic toxicity were observed in the
animals during the test period and no mortality occurred.
