Harmonised method for characterising oleochemical substances for assessment purposes.

The OECD has published a guidance for characterising oleochemical substances. The method presented gives guidance on how these complex substances can be characterised in a way that their composition is accurately and consistently reflected to ensure that substances with the same chemical composition, manufactured in different countries, can be characterised with the same description for hazard assessment purposes.

The OECD QSAR Toolbox

Four new tutorials are available that provide illustrated examples for the use of the functionalities of the Query tool , the AOP workflow for Skin Sensitization, the information form the ECHA CHEM database and the capability to analyse tautomeric structures. The examples cover both human health (skin sensitisation) and environmental (acute aquatic toxicity to fish) endpoints.

Ecotoxicology and Environmental Fate of Manufactured Nanomaterials: Test Guidelines

This document includes the conclusions and recommendations resulting from a workshop that addressed the ecotoxicology and environmental fate of manufactured nanomaterials, and in particular the applicability of existing OECD Test Guidelines (TG) related to these topics. A number of TG developments are underway at OECD as a follow-up to these recommendations.
