Abstract
Currently, the OECD has adopted three defined approaches (DAs) for eye hazard identification of non-surfactant liquids and solids (TG467) according to the three UN GHS categories (Cat.1, Cat.2, No Cat.). We are now expanding the applicability domain with a new DA for chemicals having surfactant (SF) properties (DASF). It is based on a combination of RhCE test methods (OECD TG492: EpiOcular™ EIT or SkinEthic™ HCE EIT) and a modification of the Short Time Exposure (STE, TG491) method. The aim of the current study was to compare the performance of the DASF with the performance of other NAMs currently included in the OECD TGs and with the classification based on the Draize eye test to identify potential additional DAs. The minimum performance criteria (75% Cat.1, 50% Cat.2, 70% No Cat.) used for the adoption of the DAs currently included in OECD TG467 were used for this purpose. The DASF identified 90.9% of Cat. 1 (N=23), 77.8% of Cat. 2 (N=9) and 76.0% of No Cat. (N=17) surfactants, meeting the minimum performance criteria. Some of the NAMs that are currently included in the OECD TGs seem promising methods to be part of a DA to identify Cat. 1 or No Cat. for eye hazard assessment of surfactants. However, the number of surfactants that have been tested to evaluate reliability and relevance was often too small. To date, the DASF is the only DA that has evaluated a sufficiently large number of surfactants and whose performance met the OECD acceptance criteria.
