2019 GA MEETING

The 2019 GA meeting which took place on Wednesday 8 May 2019 in Madrid, Spain was a resounding success. Hosted by FerroGlobe, the meeting which lasted 4 hours saw several deliberations related to the consortium governace, dossier updates and classification & labelling. Some key decisions taken by way of vote are as follows:

Some highlights:

  • Executive Committee: A new Chairmanand  a new 2nd Vice Chairman were appointed, meanwhile the 1st Vice Chiarman was maintained to enure continuity 
  • Dossier updates: Reveal changes in classification and labelling if compared to the 2010 submitted dossiers

IN VITRO SKIN CORROSION/ Sinter ore (Manganese ores, reduced)/ GLP

Introduction: The purpose of this test was to evaluate the corrosivity potential of the test material using the SkinEthic in vitro Reconstituted Human Epidermal (RHE) Model after treatment periods of 3 and 60 minutes. Corrosion is directly related to cytotoxicity in the SkinEthic tissue. Cytotoxicity was determined by the metabolic conversion of the vital dye MTT to formazan by viable cells in the test material treated cultures relative to the negative control. The results were used to make a prediction of the corrosivity potential of the test material. The method was designed to meet the requirements of the following:

  • OECD Guidelines for the Testing of Chemicals No. 431 “In Vitro Skin Corrosion: Human Skin Model Test” (adopted 2004)

 

Conclusion: The test material was considered not to have the potential to be corrosive in vivo.
