Safety assessment of cosmetic ingredients for skin sensitization using QSAR in silico tool

Safety assessment of cosmetic ingredients for skin sensitization using QSAR in silico tool

Skin sensitization methods are developed to protect workers and consumers from chemical exposures. In 2012, OECD Test Guideline 168 (TG) addressed the 5 Key Events (KE) of the skin sensitization Adverse Outcome Pathway (AOP)[1].

To respond to cellular and tissue events(KE2, KE3) in vitro alternative methods were well described such as OECD TG 442C (Direct Peptide Reactivity Assay, DPRA); OECD TG 442D (KeratinoSens™) and OECD TG 442E (human Cell Line Activation Test, h-CLAT). The two biomarkers based test SENS-IS and the Genomic Allergic Detection Test (GARD) are under consideration by the OECD for the development of the respective TGs.
