- Executive summary:
This in vitro study was performed to assess the corneal irritation and damage potential of D- 100 by means of the BCOP assay using fresh bovine corneae. After a first opacity measurement of the fresh bovine corneae (t0), the 20% (w/v) suspension in saline (0.9% (w/v) NaCl in deionised water) of the test item D-100, the positive, and the negative controls were applied to corneae and incubated for 240 minutes at 32 ± 1 °C. The posterior chamber contained MEM medium supplemented with sodium bicarbonate and Lglutamine and 1% fetal calf serum (FCS) (complete medium = cMEM). After the incubation phase the test item, the positive, and the negative controls were each rinsed from the corneae and opacity was measured again (t240). After the opacity measurements permeability of the corneae was determined by measuring spectrophotometrically the transfer of sodium fluorescein after incubation in a horizontal position for 90 minutes at 32 ± 1 °C. With the negative control (saline) neither an increase of opacity nor permeability of the corneae could be observed. The positive control (10% (w/v) Benzalkonium chloride in saline) showed clear opacity effects corresponding to a classification as corrosive / severe irritant to the eye (CLP/EPA/GHS (Cat 1)). Relative to the negative control, the test item D-100 did not cause any increase of the corneal opacity or permeability. The calculated mean in vitro irritation score was 0.00. According to OECD 437 the test item is classified as not corrosive / not severe irritant to the eye. In conclusion, according to the current study and under the experimental conditions reported, the test item D-100 is not corrosive / not severe irritant to the eye (CLP/EPA/GHS (Cat 1)).
