INVITRO-CONNECT GmbH offers various test strategies without animal testing for examining skin Corrosion:
- OECD 431 - Human Skin Corrosion: "In Vitro OECD 431: Reconstructed Human Epidermis Test Method, in vitro Test -
Skin Corrosion in the regulatory hazard classification and labeling context is defined as the production of irreversible damage to skin, generally evident as necrosis through the epidermis and into the dermis, following a defined chemical exposure. The In Vitro Skin Corrosion Test is an in vitro, non-animal test designed to identify those chemicals and mixtures capable of inducing skin corrosion (UN GHS Category 11), and in some cases to partially subcategorize corrosives into UN GHS Sub-Categories 1A or 1B and 1C (ie., the current test methods do not effectively discriminate between UN GHS Sub-Categories 1B and 1C).
This test method is useful for regulatory classification and labeling of chemicals and mixtures, and depending upon the regulatory jurisdiction and framework the test results may be used as standalone or to support a weight of evidence approach. Since skin corrosion in vivo typically results from rapid chemical-induced cell damage, this test method provides a mechanistically-relevant measurement of cell viability in reconstructed human epidermis (RhE) tissues after a single topically-applied chemical treatment, relative to negative control-treated tissues.
INVITRO-CONNECT has extensive expertise with a wide variety of reconstructed skin-based protocols.
NOTE: Since this test method does not discriminate among any non-corrosive categories, a non-corrosive prediction by this test method should be followed up with a test for potential skin irritation, using any of the validated Skin Irritation Test (SIT) methods, including the In Vitro Skin Irritation Test using a Reconstructed Human Epidermis (RhE) Model.
