The regulatory framework in Europe (2010/63/UE) suggests a shift from animal testing to alternative approaches, including in vitro testing. This is particularly the case in Cosmetics (Regulation 1223/2009/EC) and Chemicals Regulations (REACH and CLP), and in the recent Regulations on Plant Protection Products (1107/2009/EC) and Biocides (528/2012/EU).
VitroScreen is committed to in vitro science since 2001 and aims to be a partner to companies approaching in vitro alternatives to identify the most suitable and predictive in vitro safety testing strategy for regulatory needs.
