Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Classification: not irritating
Executive summary:

In a primary eye irritation study ( according to Appraisal of the Safety of Chemicals in foods, drugs and cosmetics, FDA Draize (1959)) 0.1 mL undiluted Decyl methacrylate, roh was instilled into the conjunctival sac of the left eye of 6 New Zealand White rabbits, (2.4 -2.6 kg body weight) for 72 hours (not rinsed). Animals were observed for 7 days. Irritation was scored according to Draize scoring and re-evalutated according OECD-GHS criteria.

In this study Decyl methacrylate, roh is not irritating to eyes.

OECD GHS Category: none

EU GHS Category: none
