Migration of 35 Siloxanes from Silicone Food Contact Materials in China and Their Potential Exposure Assessment [PDF]

open access: yesFoods
Silicone food contact materials (FCMs) pose potential health risks due to the migration of siloxanes. This study presents a comprehensive migration profiling of 35 siloxanes (cyclic D3–D22 and linear L2–L14) from 30 silicone FCMs, with migration tests ...

Direct Human Contact with Siloxanes (Silicones) – Safety or Risk Part 1. Characteristics of Siloxanes (Silicones)

open access: yesFrontiers in Pharmacology, 2016
Siloxanes are commonly known as silicones. They belong to the organosilicon compounds and are exclusively obtained by synthesis. Their chemical structure determines a range of physicochemical properties which were recognized as unique.

Polyhedral Ferrous and Ferric Siloxanes

open access: yesAngewandte Chemie - International Edition, 2004
The synthesis, isolation, and single-crystal X-ray structures of the first polyhedral ferrous and ferric siloxanes suggest that similar synthetic strategies will allow the preparation of other transition-metal siloxane frameworks.
