Applicant's summary and conclusion

Interpretation of results:
Category 2 (irritant) based on GHS criteria
Conclusions:
3 minutes and 1 hour after the test item application, the mean percent viability of the epidermis skins treated with the test item were 102.77% (considered as 100%) and 35.86%, versus 8.19% and 0.66%, respectively, with the positive control item (potassium hydroxide 8N).
In accordance with the Regulation (EC) No. 1272/2008, the results obtained under these experimental conditions enable to conclude that the test item SPANISH SAGE OIL (Salvia lavandulifolia) does not have to be classified in Category 1 “Corrosive”.
