Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The mean percent viability of the treated tissues was 83.8% versus 1.0% in the positive control (5% Sodium Dodecyl Sulfate).
In accordance with the Regulation EC No. 1272/2008, the test item D305 has to be considered as non-irritant and non corrosive to skin.
Executive summary:

The irritation potential was evaluated according OECD 439 method.

The mean percent viability of the treated tissues was 83.8% versus 1.0% in the positive control (5% Sodium Dodecyl Sulfate).

In accordance with the Regulation EC No. 1272/2008, the test item D305 has to be considered as non-irritant to skin and non corrosive.
