Abstract: Objective Using several alternative test methods strategically combination to assess eye irritation/corrosion of different concentrations of 1,2-hexanediol.Methods With the bottom-up approach,two different sensitive degree of tests,the hen’s egg test - chorioallantoic membrane (HET-CAM) and the bovine corneal opacity and permeability (BCOP) in vitro were adapted to test eye irritation of 1,2-hexanediol in different concentrations,and finally the safe range of eye irritation was confirmed by Draize eye test.Results HET-CAM test:1,2-hexanediol was non-irritant when the concentration was below volume fraction 0.625% and light irritant at volume fraction 1.25% concentration,moderate irritation at volume fraction 2.50% concentration.In the concentration of volume fraction 5.00% and 10.00%,1,2-hexanediol induced serious eye damage.BCOP test:1,2-hexanediol at volume fraction 2.50% and 5.00% concentration induced light irritation or irritation,and severe corrosive in the concentration of volume fraction 10.00%.Confirmed by the Draize test,1,2-hexanediol was non-irritant at volume fraction 5.00% concentration,light irritation at volume fraction 10.00% concentration.Conclusion In this condition,1,2-hexanediol was non-irritant with the concentration lower than volume fraction 5.00%.
