Additional information

In Vitro Skin Corrosivity

An in vitro skin corrosivity test of the test item BAL0001026 was performed in a reconstructed human epidermis model.

Disks of EPISKINTM(SM) were treated with BAL0001026 and incubated for 4 hours at room temperature. Exposure of test material was terminated by rinsing with Phosphate Buffered Saline solution.

Following exposure to BAL0001026, the mean cell viability was 92.9% compared to the negative control, which is above the threshold of 35%, therefore the test item was considered as being non-corrosive.

In conclusion, in this in vitro EPISKIN™(SM) test model, the results indicate that BAL0001026 is non-corrosive to skin.

In Vitro Skin Irritation

An in vitro skin irritation test of BAL0001026 test item was performed in a reconstructed human epidermis model.

Disks of EPISKINTM (SM) (three units) were treated with the test item and incubated for 15 minutes at room temperature. Exposure to the test item was terminated by rinsing with Phosphate Buffered Saline (PBS). The epidermis units were then incubated at 37 °C for 42 hours in an incubator with 5% CO2 in a >95% humidified atmosphere.

Following exposure with BAL0001026, the mean cell viability was 100.6% compared to the negative control. This is above the threshold of 50%, therefore the test item was considered as being non-irritant to skin. The experiment met the validity criteria, therefore the study was considered to be valid.

In conclusion, in this in vitro EPISKINTM (SM) model test with BAL0001026 (Batch number: 014), the results indicate that the test item is non-irritant to skin (No Category).

In Vitro Eye Irritation

An in vitro eye irritation study was performed in isolated chicken’s eyes on the test item, BAL0001026.

The study was conducted in 2 stages; the first experiment (Experiment I) provided an initial assessment of the irritation potential of the test item which was confirmed in a second experiment (Experiment II).

 

Experiment I: No significant corneal swelling (mean ≤5%) was observed during the four-hour observation period on test item treated eyes. No cornea opacity change (severity 0.5 on two eyes and no cornea opacity change on one eye) was observed on test item treated eyes. No significant fluorescein retention change (severity 0.5) was noted on test item treated eyes. Test item was stuck on all corneal surfaces after the post-treatment rinse. One corneal surface was cleared at 240 minutes after the post-treatment rinse. Minimal amount of test item was observed on the corneal surfaces in two eyes at 240 minutes after post-treatment rinse.

Experiment II: No significant corneal swelling (mean ≤5%) was observed during the four-hour observation period on test item treated eyes. No significant cornea opacity change (severity 0.5) was observed on test item treated eyes. No significant fluorescein retention change was noted on test item treated eyes. The test item was stuck on all corneal surfaces after the post-treatment rinse. The two corneal surfaces were cleared at 240 minuntes post-treatment rinse. Minimal amount of test item was observed on the corneal surface in one eye at 240 minutes post-treatment rinse.

Based on these in vitro eye irritation assay in isolated chicken eyes with BAL0001026, the test item was non-irritant: UN GHS Classification: No Category.

Justification for classification or non-classification

Skin Irritation / Corrosion

Based on the results of a corrosivity test the test item is non-corrosive.

In conclusion, the results indicate that BAL0001026 is non-irritant to skin (No Category).

Eye Irritation

Based on the in vitro eye irritation assay in isolated chicken eyes with BAL0001025, the test item was non-irritant: UN GHS Classification: No Category.
