HSSD Tool

HSSD Tool

This software was developed by a consortium of partners to facilitate the uptake of novel approaches to estimate aquatic threshold concentrations (e.g. the concentration at which 5% of the species are exposed above their EC50, HC5).

ECETOC publishes Joint Assessment of Commodity Chemicals (JACC) Report No. 55 on Linear Polydimethylsiloxanes CAS No. 63148-62-9 (Second Edition)

The findings of an ECETOC task force on Linear Polydimethylsiloxanes have been published as ECETOC JACC Report No. 55.

This report presents a critical evaluation of the toxicity, physico-chemical properties, and environmental fate and effects of linear polydimethylsiloxanes (PDMSs), a type of non-volatile (odourless), fluid (viscous) "silicones" that are virtually insoluble in water. PDMSs are widely used in industrial, consumer, food and medicinal or pharmaceutical applications. The report has been produced as part of the ECETOC Joint Assessment of Commodity Chemicals (JACC) programme and updates an earlier ECETOC review: JACC Report No. 26 (September 1994).

The ECETOC Chemicals Programme Manager, Ir. Henk Vrijhof, was Scientific Secretary to the task force.

The PDF of the report can be freely downloaded from the ECETOC website at https://www.ecetoc.org/publications ; the quick link to the Executive Summary and download page is http://bit.ly/ecetoc-jacc55
