Regulatory assessments in Europe should focus on exposure and potential risk, not just hazard

WASHINGTON (May 1, 2015) - Environment and Health Canada recently published their final screening assessment for the siloxanes L3, which concluded that L3 is not entering the environment in a way that constitutes a danger in Canada to human health or the environment. Consequently, L3 will not be subject to any regulatory restrictions in Canada. 

"The high-quality, comprehensive risk-based assessment by Canada reinforces the extensive body of evidence concluding L3 in the environment does not pose a threat to human health or the environment," said Karluss Thomas, executive director of the Global Silicones Council and senior director of the  Silicones Environmental, Health, and Safety Center of the American Chemistry Council. "Canada's conclusion supports that L3 can continue to be safely used in personal care formulations, and to produce silicone polymers, which are vital for maintaining the performance of a number of product categories , including: medical applications, transportation equipment and building and construction materials. In addition, Canada's conclusion for siloxanes L3, D4 and D5 represent a stark contrast to assessments conducted under the current REACH regulation by European officials for D4 and D5, which don't appropriately consider environmental exposure or risk."

The Canadian Chemicals Management Program (CMP) is a systematic program that evaluates the safety of chemicals in commerce in Canada. The CMP is highly regarded by scientific experts as a world-class, risk-based program that effectively evaluates chemicals using the weight of evidence (WoE) approach and with appropriate consideration of exposure.

Canada's assessment concluded that L3 is not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity, or that constitute or may constitute a danger to the environment on which life depends. The assessment also concluded that L3 is not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.

"Silicones are some of the most widely-studied chemicals used in consumer products and industrial applications. We continue to support the safe and responsible use of silicone materials and fully support Canada's use of risk-based weight-of-evidence assessments for effective environmental and human-health decision-making," said Thomas.
