Since the application of silicone oil, research and discussion on its safety have been ongoing. At present, there have been a large number of research reports related to the safety of silicone oil, covering the impact on the environment, animals and plants and the human body. Sensitivity, physical safety, chemical safety, toxicology and other perspectives were analyzed. The United States established the Cosmetic Ingredient Evaluation Expert Group (CIR) in 1976. The Evaluation Expert Group conducted a systematic analysis and evaluation of silicone raw materials. In 2003, 2011, 2014, and 2016, it released linear polydimethylamines. Silicone and other silicone raw material safety reports include that silicone oil is a safe substance and can be used as a raw material for cosmetics. In 2011, European Chemical Industry Ecology and Toxicology Center (ECETOC) released a safety assessment report on linear polydimethylsiloxane, pointing out the safety risks of this type of silicone oil products to the environment, animals and plants and human Very low.
