Applicant's summary and conclusion
- Interpretation of results:
- other: CLP/EU GHS criteria not met, no classification required according to Regulation (EC) No 1272/2008.
- Conclusions:
- CLP: not classified
- Executive summary:
Eye irritation of the test substance (CAS 91744-23-9, Glyceryl Citrate/Lactate/Linoleate/Oleate) was investigated in a study according to OECD 405 and GLP. 0.1 cm³ of the test substance were instilled in one eye each of the three New Zealand White rabbits. Total exposure was 24 h. Thereafter, the test substance was removed using warm physiological saline.
Observations were made after 1, 24, 48, and 72 h after administration. The untreated eye of each animal served as control.
Marked hyperaemias of some blood vessels could be observed in all animals 1 h after application, after 24 hours no effects was noticed. Mean scores for cornea, iris, conjunctivae redness and conjunctivae chemosis after 24, 48, and 72 h were 0 for each endpoint.
Based on the results of this test the substance is classified as not irritating.
