Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- 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 conjuntiva: 0.0
Oedema of conjunctiva: 0.0 - Executive summary:
To test the acute irritant effect of coconut oil, reaction products of coconut fatty acid mono- or diglyceride with trimethylolpropaneethoxylate 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 exposoure for 72 hours, the eyes were washed out with warm physiological saline. The test was carried out according to OECD guideline 405 (24 Feb 1987).
The test showed that administration of coconut oil, reaction products of coconut fatty acid mono- or diglyceride with trimethylolpropaneethoxylate caused no irritation reactions.
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 coconut oil, reaction products of coconut fatty acid mono- or diglyceride with trimethylolpropaneethoxylate was judged to be non irritating to eyes and mucosa.
