AB  - Recently, several non-animal approaches contributing to the identification of 
      skin sensitisation hazard have been introduced. Their validation and acceptance 
      has largely been directed towards regulatory classification. Considering the 
      driving force for replacement of in vivo tests centred on cosmetics, it is 
      reasonable to ask how well the new approaches perform in this respect. In the 
      present study, 219 substances, largely cosmetic raw materials (including dyes, 
      preservatives and fragrances), have been evaluated in our Defined Approach 
      integrating a stacking meta model (version 5), incorporating the individual 
      outcomes of 3 in vitro validated methods (Direct Peptide Reactivity Assay, 
      Keratinosens, U-SENS), 2 in silico tools (TIMES SS, TOXTREE) and 
      physicochemical parameters (volatility, pH). Stacking meta model outcomes were 
      compared with existing local lymph node assay (LLNA) data. Non-sensitisers 
      comprised 68/219; 86 were weak/moderate and 65 were stronger sensitisers. The 
      model version revision demonstrate the gain to discriminate sensitizers to 
      non-sensitiser when the in silico TIMES model is incorporated as input parameter. 
      The 85% to 91% accuracy for the cosmetics categories, indicates the stacking meta 
      model offers value for the next generation risk assessment framework. These 
      results pinpoint the power of the stacking meta model relying on a confidence 
      based on the probability given in any individual prediction.
