Eye Irritation Test (OECD TG 492)

The EpiOcular Eye Irritation Test predicts the acute eye irritation potential of a topically applied chemical or formulation by measurement of its cytotoxic effect of the EpiOcular cornea epithelial model. This in vitro hazard assessment allows for the identification of chemicals (substances and mixtures) not requiring classification and labeling for eye irritation or serious eye damage in accordance with UN GHS.

MatTek offers the EpiOcular Eye Irritation Test as a GLP or non-GLP service.
