Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

Under the conditions of this guideline study 1,2,4-Benzenetricarboxylic acid, mixed decyl and octyl triesters was not irritating to the eyes. 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 conjuntiva: 0.0, Oedema of conjunctiva: 0.0.

Executive summary:

To test the acute irritant effect of 1,2,4-Benzenetricarboxylic acid, mixed decyl and octyl triesters on the eyes and mucosa, 0.1 cm³ of the liquid test substance was administered into the conjunctival sac of one eye of each of three male rabbits. After exposure for 72 hours, the eyes were washed out with warm physiological saline. The test was carried out according to OECD guideline 405 (12 May 1982).

The test showed that administration of 1,2,4-Benzenetricarboxylic acid, mixed decyl and octyl triesters caused no irritation reactions at cornea and iris. At the conjunctivae 1 hour after application circumcorneal injections in all animals and mild discharge in one animal were observed, 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 conjuntiva: 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.
