- RECONSTRUCTED HUMAN EPIDERMIS (RHE) TISSUE
- The 0.50 cm² reconstructed epidermises (Episkin SA, RHE/S/17 Batch No. 17-RHE-116) were received on 13 November 2017. The same day, the insert (filter + epidermis) was gently removed
from the agarose while avoiding leaving agarose on the polycarbonate filter. The inserts were placed in 6 wells culture plate which had been previously filled with 1 mL of growth medium (Episkin SA, batch No. 17 SGM 033) during 2 hours and 05 minutes. Then just before treatment, the inserts were placed in 24 wells culture plate which had been previously filled with 300 μL of maintenance medium (Episkin SA, batch No. 17 SMM 022). The two killed Reconstructed Human epidermis control tissue models, supplied by Episkin (Batch No. 17-RHE-021) were defrost on 21 February 2017, re-freeze on 21 February 2017 and defrost to be used on 28 February 2017.
TREATMENT
- The test item was applied, as supplied, at the dose of 16 µL, to the epidermal surface of 3 living human skin models and 2 killed Reconstructed Human epidermis (for non-specific MTT reduction control) during 42 minutes at room temperature. To ensure a good contact with the epidermises, during all the treatment period, the test item was recovered with a nylon mesh provided by Episkin SA.

- Executive summary:
The aim was to evaluate the possible irritating effects of the test item HUILE ESSENTIELLE MYRRHE SOMALIE 100% pure et naturelle after topical application on in vitro human reconstructed epidermis (SkinEthic RHE® model).
The test item HUILE ESSENTIELLE MYRRHE SOMALIE 100% pure et naturelle was applied as supplied at the dose of 16 μL, to 3 living Reconstructed Human epidermis (SkinEthic RHE® model) during 42 minutes. The application was followed by a rinse with 25 mL of DPBS and a 41 hours and 50 minutes post-incubation period at 37°C, 5% CO2. Cell viability was then measured by enzymatic conversion of the vital dye MTT into a blue formazan salt that was quantitatively measured after extraction from tissues. The experimental protocol was established in accordance with O.E.C.D. Test Guideline No. 439 adopted 28 July 2015 and the Test method B.46 of Council regulation No. 761/2009 dated 23 July 2009 (EU Journal L220) - ATP Council regulation No. 440/2008 of 30
May 2008 (E.U. Journal L142).
The mean percent viability of the treated tissues was 92.5% versus 1.2% in the positive control (5% Sodium Dodecyl Sulfate).
In accordance with the Regulation EC No. 1272/2008, the test item HUILE ESSENTIELLE MYRRHE SOMALIE 100% pure et naturelle has to be considered as Non-irritant to skin. It corresponds to UN GHS No Category.
No hazard statement or signal word is required.
