Applicant's summary and conclusion
- Interpretation of results:

- Executive summary:
Purpose of the study is to evaluate the skin irritation potential on Reconstructed Human Epidermis (RHE SkinEthic) of the test item "OZONIA 3000 SUNFLOWER (OZONIZED SUNFLOWER SEED OIL)" according to the method described in OECD 439 and in compliance with Good Laboratory Practice. This method uses human artificial skin models to assess the skin irritation of chemical substances and mixtures and to properly label them to this respect, if applicable. The test is based on the evaluation of cell survival after the exposure to the test item through MTT assay and by comparison with epidermis treated with phosphate buffer only (negative control). The MTT method is a colorimetric assay that allows to determinate the percentage of cells alive within an in vitro cultured tissue. This assay is based on the ability of the mitochondria, succinate dehydrogenase enzyme to metabolise the nitro-blue tetrazolium salt, giving a coloured compound that can be measured by spectrophotometer reading. The test item "OZONIA 3000 SUNFLOWER (OZONIZED SUNFLOWER SEED OIL)" in the experimental conditions here described, showed a mean cell survival of 102.4% (±3.0), so it resulted a NOT SKIN IRRITANT (UN-GHS - no Category), because its cell viability is higher than 50%
The positive control Sodium Dodecyl Sulphate (SDS) showed a mean cell viability of 1.0% (±0.0), so it gave the expected results. All the acceptance criteria were passed.
