- Executive summary:
A study was conducted to evaluate the skin irritation potential of the test substance according to a method similar to OECD Guideline 492. MatTek EpiOcular tissue samples were exposed to undiluted substance for 16, 64 or 256 min. Following treatment, the viability of the tissues was determined using MTT uptake and conversion, and the absorbance of each sample was measured at 540 nm using a reference wavelength of 690 nm. The viability was then expressed as a percent of the control values. The mean percent viability for each time point was used to calculate an ET50 which represents the time at which the EpiOcular tissue viability was reduced by 50% compared to the control tissues. The substance produced an ET50 > 256 min, indicating that it was non- to minimally irritating under the study conditions (DeGeorge, 2002).
