The test substance was applied to EpiDerm Reconstructed Human Epidermic (RhE) tissue unchanged for a 1 hour exposure. DPBS was used as a negative control and 5% SDS was used as positive control. The tissues were washed with DPBS and analyzed with an MTT assay. The percent tissue viability of the two lots were 96% and 101%.

- Executive summary:
A GLP-compliant, OECD Guideline 492 in vitro eye irritation test was performed with rosin acid derivative. 50mg of the test article was applied to EpiOcular Reconstituted Human Cornea-like Epithelium (RhCE) and the treated tissue was incubated for 6-hours. Three replicates were performed. 50mL of sterile was was used as a negative control and 50mL of methyl acetate was used as a positive control. Following treatment, an MTT assay was performed to assess tissue viability as percent of the negative control. The data for the lots was 89% and 103% tissue viability. A mean tissue viability percentage of greater than 60% indicates that no classification is required. Based on the OECD Guideline 492 prediction model, rosin acid derivative is not classified for eye irritation.
