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.
