These substances are basic members of the silicone family, serving as the building blocks for many silicones. They are used to create a diverse range of silicone materials, called polymers that provide beneficial characteristics to a wide variety of applications and products. D4, D5, and D6 are most frequently used as raw materials, meaning that the substance is employed in the manufacturing process but is only present at very low levels in the end products.
D4, D5, and D6 are some of the most extensively studied chemicals used in consumer applications. The data generated from studies assessing D4, D5, and D6 support their safety when the products in which they are a component are used as intended.
Silicone polymers have an exceptional breadth of chemical and physical properties, and can be manufactured in many forms, including:
Silicones can be made to resist moisture, chemicals, heat, cold, and ultraviolet radiation. Because of these and other properties, they are utilized in thousands of products in applications including construction, consumer products, electronics, energy, healthcare, and transportation.
Among the GSC’s objectives are promotion of safe use and stewardship of silicones globally. To accomplish its mission, the GSC undertakes the following activities:
- Monitor the environmental, health, and safety activities of the three RSIAs and coordinate activities on a global basis.
- Proactively promote industry communication with regulatory bodies around the world and with international environmental, health, and safety organizations, such as the World Health Organization, the Organization of Economic Cooperation and Development, and the United Nations.
- Through the RSIAs, identify and anticipate opportunities to enhance environmental, health, and safety research relating to silicones and engage in global projects to communicate the industry’s product stewardship commitment.
- The global silicone industry extensively studies the human health and environmental impacts of its products. Science advisory boards, which include nationally and internationally renowned scientists, are used occasionally to provide independent reviews of the testing strategy, methodology, and findings of these studies. Universities, qualified contract laboratories, and Industry laboratories perform and review the tests and studies. Research results are regularly published in peer-reviewed journals.
