Polysiloxanes, the scientific name for silicones, possess exceptional properties, and are used in numerous fields ranging from cosmetics to aerospace. They are absolutely everywhere! However, they have a major flaw, as small, cyclic oligosolixanes—toxic for the environment and identified as an endocrine disruptor—form during their synthesis. To correct this drawback, a team of scientists 1 led by a CNRS researcher recently developed a new process for synthesising silicones in a cleaner and more environmentally-friendly manner by preventing the formation of these small cyclic oligosolixanes. The results will appear in Science on 1 September, and could have a considerable impact on the industrial sector.
