Applicant's summary and conclusion

Interpretation of results:
Category 1 (irreversible effects on the eye)
Remarks:
Migrated informationCriteria used for interpretation of results: EU
Conclusions:
Rosin, fumarated is considered to be an eye irritant in rabbits when tested using a method similar to OECD Guideline 405. Rosin, fumarated is classified for eye irritation in Annex I of Directive 67/548/EEC. Based on the minimal signs of irritation noted during the study, the reported Draize scores, the number of affected animals for each category, and the duration of response, this material is classifiable for eye irritation according to UN Globally Harmonized System of Classification and Labelling of Chemicals (GHS) or EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
Executive summary:

In this study the potential for rosin, fumarated (0.1 g) to cause eye irritation was evaluated after instillation into the eyes of one New Zealand White rabbit. The animal was observed and then terminated 5 hours after application. After 5 hours, the substance was found to be a severe eye irritant, and further testing was therefore not warranted.
