Injection of the conjunctival blood vessels and moderate discharge were apparent in all treated eyes one hour after instillation. Conjunctival injection persisted in one case until the 48 hour assessment. The treated eyes of two animals were overtly normal 24 hours after instillation and the third animal was overtly normal 48 hours later.
Instillation of the test material gave rise to practically no initial pain response.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The highest total mean score was 6.0 occurring at the one-hour observation; accordingly under the criteria Kay and Calandra (1962) Reaction product of 3,5,5-trimethyl-hexanoic acid and 2-metheylpropanoic acid and pentaerythritol was classified as “minimally irritating” to the eye. Tetraesters of pentaerythritol with 2- methylpropanoic acid and 3,5,5-trimethyl-hexanoic acid does not require labelling in accordance with European Commission Regulation 1272/2008.
- Executive summary:
OECD 405 (2012) - In a primary eye irritation study (OECD 405), undiluted Tetraesters of pentaerythritol with 2-methylpropanoic acid and 3,5,5-trimethyl-hexanoic acid was instilled into the conjunctival sac of the right eye of three female New Zealand White rabbits. The left eye was left untreated. Neither eye was washed during the course of the test. Animals were then observed at 1, 24, 48 and 72 hours. Irritation was scored by the method of Kay and Calandra (1962).
There was no sign of toxicity or ill health in any rabbit during the observation period. Injection of the conjunctival blood vessels and moderate discharge were apparent in all treated eyes one hour after instillation. Conjuctival injection persisted in one case until the 48 h assessment. The treated eyes of two animals were overtly normal 24 h after instillation and the third animal was overtly normal 48 h later. Instillation of the test item gave rise to practically no initial pain response.
The highest mean score was 6.0, occurring at the 1 h observation (for conjunctiva). This was fully reversed by the 72 h timepoint in all animals.
Tetraesters of pentaerythritol with 2-methylpropanoic acid and 3,5,5-trimethyl-hexanoic acid does not require classification or labelling in accordance with EC Commission Regulation (No.) 1272/2008.
