There is nothing more important to us than the safety of our products. Over 35 years of scientific research have been dedicated to assess the safety of silicones relative to workers, consumers, the environment and manufacturing processes.
The results of this continuous research and testing demonstrate that silicones are safe in their diverse and important applications, which contribute enormously to comfort, safety and enjoyment in our daily lives.
Committed to the responsible use of silicones, the industry continues to evaluate the science behind the materials through several rigorous research programs. Research methods include computer modeling, laboratory testing, environmental monitoring and other approaches.
Numerous regulations in the EU and its member countries as well as international conventions ensure that chemicals and the products they are used in are safe for consumers and workers. On these pages you will find out more about some of the most important European regulations.
“We cooperate closely with regulatory agencies and panels in Europe and internationally, and share new research data with them as it becomes available.”
As with many other products, the intermediates to make final silicones need to be handled correctly to ensure safety, for example, at work, in storage and in transportation. This is known as ‘operating safety’.
Chlorosilanes are intermediates used to manufacture siloxanes and silanes – the building blocks for many silicone products. Chlorosilanes are therefore not found in final applications.
There are eight main chlorosilanes: dimethyldichlorosilane, methyltrichlorosilane, trimethylchlorosilane, methyldichlorosilane, vinyltrichlorosilane, phenyltrichlorosilane, trichlorosilane and silicon tetrachloride.
All of these are clear liquids that react readily with water to form corrosive and toxic hydrogen chloride gas and hydrochloric acid. All except silicon tetrachloride and phenyltrichlorosilane are also flammable.
“These substances therefore need to be handled with care by producers and customers. For this reason CES has developed a guide to the Safe Handling of Chlorosilanes.“
It provides information on the hazards of chlorosilanes and suggestions for their safe handling and use. In addition, users of chlorosilanes should obtain Material Safety Data Sheets (MSDS) from the relevant manufacturer.
