Silicones hold a prominent place in the European Union (EU) cosmetics industry, serving as versatile ingredients in a wide array of skincare, haircare, and makeup products. These compounds, derived from silicon, oxygen, carbon, and hydrogen, offer unique properties that contribute to the efficacy, stability, and sensory appeal of cosmetic formulations. In the EU, the use of silicones in cosmetics is governed by strict regulatory standards outlined in the EU Cosmetics Regulation (Regulation (EC) No 1223/2009). This legislation mandates comprehensive safety assessments of cosmetic ingredients, including silicones, prior to their introduction into the market. As a result, silicone-based cosmetic products available in the EU undergo rigorous testing to ensure consumer safety and compliance with regulatory requirements.
