- overall irritation score
- Basis:
- mean
- Time point:
- other: 5 days
- Reversibility:
- fully reversible within: 5 days
- Remarks on result:
- probability of weak irritation
- Irritant / corrosive response data:
- Signs of irritation included moderate immediate discomfort, lacrimation together with moderate erythema and edema, and a slight cloudiness of the corneal area. A slight degree of inflammation was present in 1 rabbit after 72-hour. These effects were completely reveresible in 5 days
Applicant's summary and conclusion
- Interpretation of results:
- other: not irritating
- Conclusions:
- Signs of irritation observed in rabbits included moderate immediate discomfort, lacrimation together with moderate erythema and edema, and a slight cloudiness of the corneal area. A slight degree of inflammation was present in 1 rabbit after 72-hour.These effects were fully reversible in 5 days.
Since the observed effects were reversible in 5 days,1,2-Dichloro-4-nitrobenzene can be considered to be not irritating to rabbit eyes. - Executive summary:
The ocular irritation potential of 1,2-Dichloro-4-nitrobenzene was assessed in rabbits.
Undiluted 0.1 ml 1,2-Dichloro-4-nitrobenzene was instilled in the conjunctival sac of the right eye of 3 albino rabbits (1 female and 2 males). The rabbit were observed for signs of irritation till 5 days.Signs of irritation observed in rabbits included moderate immediate discomfort, lacrimation together with moderate erythema and edema, and a slight cloudiness of the corneal area. A slight degree of inflammation was present in 1 rabbit after 72-hour.These effects were fully reversible in 5 days.
Since the observed effects were reversible in 5 days,1,2-Dichloro-4-nitrobenzene can be considered to be not irritating to rabbit eyes.
