Test animals / tissue source
- Species:
- human
- Details on test animals or tissues and environmental conditions:
- - Justification of the test method and considerations regarding applicability: In a prevalidation study performed by Avon Products Inc. and MatTek Corporation, the in vitro eye test using the human cornea model EpiOcular™ and measurement of cell viability by dehydrogenase conversion of MTT into a blue formazan salt have indicated this method as a sufficiently promising predictor for eye irritancy potential. The EpiOcular ™ Eye Irritation Test (EIT) was validated by the European Union Reference laboratory for Alternatives to Animal Testing (EURL ECVAM) and cosmetics Europe between 2008 and 2013.
- Description of the cell system used, incl. certificate of authenticity and the mycoplasma status of the cell live: EpiOcular™ tissue consists of normal, human-derived epidermal keratinocytes which have been cultured to form a stratified squamous epithelium similar to that found in the human cornea. It consists of highly organized basal cells which progressively flatten out as the apical surface of the tissue is approached, analogous to the normal in vivo corneal epithelium.

- Description of the method used to quantify MTT formazan:
- Description of the qualification of the HPLC/UPLC-spectrophotometry system (if applicable): Not applicable
- Description of evaluation criteria used including the justification for the selection of the cut-off point for the prediction model: If the test item-treated tissue viability is > 60 % relative to the negative control treated tissue viability, the test item is labelled non-irritant. If viability is ≤ 60 % of treated negative control, the test item is labelled irritant.

- Reference to historical data of the RhCE tissue construct: Historic data from July 2015 to February 2016 show the postive control range of viabiltiies of 6.90 % - 40. 4 %. The range of absorbance for historic postive control data is 0.107 - 0.849 and for negative control data 1.27 - 2.05.
- Demonstration of proficiency in performing the test method before routine use by testing of the proficiency chemicals: Historical report data reported.
- Positive and negative control means and acceptance ranges based on historical data: Positve control - mean viability: 32.0 %, range: 6.90 - 40.4 %, mean absorption: 0.538, range 0.107 - 0.849. Negative control - mean absorption: 1.65, range 1.27 - 2.05
