Abstract: This research paper provides a comprehensive, multi-disciplinary analysis of silicone polymers (polysiloxanes), specifically focusing on the 2010–2020 decade. Driven by their unique inorganic-organic hybrid structure, polysiloxanes have become indispensable in biomedical, aerospace, and cosmetic applications. This paper details the chemical synthesis, structural advantages, and the exponential growth of global consumption, which reached 5.5 million metric tons by 2020. Crucially, this report investigates the paradoxical nature of silicones: while high-molecular-weight polymers exhibit high biocompatibility, their low-molecular-weight cyclic precursors and degradation products (such as D4, D5, and D6) pose significant toxicological and ecological risks. We analyze health controversies surrounding silicone breast implants, and present modeled environmental data illustrating the bioaccumulation of cyclic volatile methylsiloxanes (cVMS) in global aquatic ecosystems. To provide clarity on their versatile applications, a dedicated tabular analysis maps out their widespread uses across major industrial sectors. By integrating structural chemistry diagrams, empirical usage statistics, and an extensive theoretical literature review, this paper establishes a robust framework for understanding the environmental and health dynamics of silicone polymers up to the year 2020.
