Any other information on results incl. tables
The test item, Butanedioic acid, sulfo-, 1-C12-18-alkyl esters, disodium salts, was applied to the skin surface. Dulbecco’s phosphate buffered saline (D-PBS) was used as the negative control. 8 N KOH was used as the positive reference item. Two exposure times of 3 minutes or 1 hour were employed.
In comparison to the negative controls, the mean viability of cells exposed to the test item was 78.8% after a 3-minute exposure period and 74.9% after a 1-hour exposure. The OD540 values were well above the cut-off percentage cell viability values distinguishing corrosive from non-corrosive test items of <50% or <15% for a 3-minute or 1-hour treatment, respectively. Therefore, the test item was non-corrosive in this skin model and is predicted to be non-corrosive to human skin.
The mean viability of cells treated with the positive reference item 8 N KOH were 0.5% (3-minute incubation) and <0.1% (1-hour incubation) of the negative controls and were below the cut-off values. Hence, 8 N KOH caused pronounced corrosion in this skin model and is predicted to be corrosive to human skin.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the present test conditions the test itemapplied at two exposure times of 3 minutes or 1 hour was predicted non-corrosive to skin in an experiment employing an artificial three-dimensional model of human skin.
- Executive summary:
The purpose of this study was to determine cytotoxic properties to skin cells which might lead to corrosion by test item to human skin, in an experiment with an artificial three-dimensional model of human skin. The EST-1000 model was employed. The test item was applied to the skin surface. Dulbecco’s phosphate buffered saline (D-PBS)was used as the negative control.8 N KOHwas used as the positive reference item.Two exposure times of 3 minutes or 1 hour were employed.
In comparison to the negative controls, the mean viability of cells exposed to the test item was 78.8% after a 3-minute exposure period and 74.9% after a 1-hour exposure.The OD540values were well above the cut-off percentage cell viability values distinguishing corrosive from non-corrosive test items of <50% or<15% for a 3-minute or 1-hour treatment, respectively.Therefore, the test item was non-corrosive in this skin model and is predicted to be non-corrosive to human skin.The mean viability of cells treated with thepositive reference item 8 N KOH was 0.5% (3-minute incubation) and <0.1% (1-hour incubation) of the negative controls and below the cut-off values. Hence, 8 N KOH caused pronounced corrosion in this skin model and is predicted to be corrosive to human skin.
Under the present test conditions the test item containing >95% active ingredient, tested at two exposure times of 3 minutes or 1 hour, was non-corrosive to skin in an experiment employing an artificial three-dimensional model of human skin.
