23rd International Congress of the European Society of Toxicology In Vitro (ESTIV 2026)
The 23rd ESTIV Meeting is being held on 29 June – 2 July 2026 in Maastricht, The Netherlands.
Unilever is sponsoring the 23rd ESTIV Congress, an event that brings together the toxicology community to advance in vitro and in silico approaches. ESTIV Congress provides a collaborative platform to share scientific innovation, discuss regulatory progress, and strengthen connections across academia, industry, and government, supporting the transition towards non-animal methodologies and modern safety assessment.
Unilever SERS scientists have co-authored six oral, one poster presentations and will be co-chairing two sessions – details below:
