- no
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.1 ml - Duration of treatment / exposure:
- 72 hours
- Observation period (in vivo):
- None - Due to an almost total lack of reaction during the 72 hours after dosing, the study was terminat(ed, according to protocol, after this observation. Therefore no scoring or observations were performed at 7, 14 or 21 days.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- DEGDN did not produce sufficient irritation under conditions of this study to be classified as an ocular irritant.
- Executive summary:
The potential for diethyleneglycol dinitrate (DEGDN) to produce primary eye irritation was evaluated in six male New Zealand White rabbits by using a modified Draize method. DEGDN produced no response indicative of a potential to cause irritation upon direct contact with the eye. Slight iridial vasodilation (one of six rabbits) and slight conjunctival vasodilation and swelling, indicative of mild inflammation, (three of six rabbits) were the most serious responses observed. DEGDN was classified as a non-irritant under conditions of this study.
