Intertek provides high quality customer-focused services for both skin irritation and corrosion employing validated, in vitro methods for a wide range of cosmetics, raw materials and personal care products. Intertek uses in vitro skin models to study the potential cytotoxic effects of skin applied treatments or chemicals. The models, based on human reconstructed epidermis which approximates the barrier of normal human skin. Topical application of a substance mimics the route of human exposure and ECVAM validated methods for Skin irritancy and corrosion can be carried out using these skin models.
