IN-LIFE DATES: From:8-January-1991 To:15 January 1991

Test system

unchanged (no vehicle)
other: treated animals served also as control (one eye TCPP, the other remained untreated and served as control)
Amount / concentration applied:
100 µl TCPP in one eye.
Duration of treatment / exposure:
24 h
Observation period (in vivo):
7 d
Number of animals or in vitro replicates:
3 females
Details on study design:
A volume of 0.1 ml of the test material was instilled into the conjunctival sac of one eye of each of three rabbits. The other eye remained untreated and served as control. The treated eyes were rinsed with saline 24 hours post-treatment.

Results and discussion

In vivo

Irritation parameter:
overall irritation score
Time point:
24/48/72 h
Max. score:
other: not applicable; observation time 7 days
Remarks on result:
no indication of irritation
Irritant / corrosive response data:
There were no signs of irritation in any of the treated eyes at any of the observation times of 24, 48 and 72 hours. One animal had evidence of aqueous humour discharge at 48 hours, but this did not persist.

Applicant's summary and conclusion

Executive summary:

The irritant/corrosive potential of the test substance TCPP was studied on the eye of the rabbit in accordance with the OECD Guideline No. 405 for testing of Chemicals.

The results of this experiment indicate that the test substance is not irritating to the eye.

The substance does not have a significant local irritating potential to the eye.
