Applicant's summary and conclusion

Interpretation of results:
other: Irritating
Remarks:
Criteria used for interpretation of results: EU
Conclusions:
Resin acids and rosin acids, fumarated, esters with glycerol is considered to be an eye irritant in rabbits when tested using a method similar to OECD Guideline 405.

Resin acids and rosin acids, fumarated, esters with glycerol 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 a primary eye irritation study, 0.1 gram of UNI-REZ 757 (resin acids and rosin acids, fumarated, esters with glycerol) was instilled into the conjunctival sacs of each of six young adult New Zealand white rabbits. The remaining eye of each rabbit served as a control.  Ocular reaction for each animal was recorded at 24, 48, and 72 hours post-treatment and scored. The mean eye irritation score was determined for each observation period. The overall mean eye irritation scores (± S.D.) out of a possible 110 points were 21.5 (± 6.3) at 24 hours, 13.2 (± 3.9) at 48 hours, and 4.3 (± 3.3) at 72 hours. All treated eyes were normal by the 7-day examinations. Based on the scoring and classification systems in the study report, the test substance was considered to be irritating to rabbit eyes.

Substance tested is a rosin adduct ester. On structural and synthetic grounds it is probable that the substance is similar to the test substance. Thus, on animal welfare grounds a further test should not be undertaken.
