Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The following mean values, based on the results from the 24 -, 48 - and 72 hour-readings were calculated:
Cornea opacity: 0.0
Iris lesion: 0.0
Redness of conjunctiva: 0.0
Oedema of conjunctiva: 0.0
Based on the result of this study 1,2,4-Benzenetricarboxylic acid, mixed decyl and octyl triesters was judged to be non irritating to eyes and mucosa.
Executive summary:

Eye irritation of a structural analogue of the substance (1,2,4 -Benzenetricarboxylic acid, mixed decyl and octyl triesters) has been investigated in the rabbit using methods in accordance with OECD guideline 405.

Administration of 1,2,4 -Benzenetricarboxylic acid, mixed decyl and octyl triesters caused no irritation reactions of the cornea or iris. Mild conjunctival redness was seen in all animals after 1 hour and mild discharge was noted in one animal. After 24 hours all animals were free of symptoms. The following mean values, based on the results from the 24 -, 48 - and 72 hour-readings were calculated: Cornea opacity: 0.0; Iris lesion: 0.0; Redness of conjunctiva: 0.0; Oedema of conjunctiva: 0.0

Based on the result of this study 1,2,4-Benzenetricarboxylic acid, mixed decyl and octyl triesters was judged to be non irritating to eyes and mucosa.
