1. Security
Since the application of silicone oil, research and discussion on its safety have been ongoing. There are currently a large number of research reports related to the safety of silicone oil, covering the impact on the environment, animals, plants and human body, from natural decomposition, biological metabolism, Analyzes were conducted from multiple perspectives including sensitivity, physical safety, chemical safety, and toxicology. The United States established the Cosmetic Ingredients Review (CIR) in 1976. The evaluation expert group conducted systematic analysis and evaluation of silicone raw materials, and released reports including linear polydimethylmethane in 2003, 2011, 2014 and 2016. Safety reports on various silicone raw material products, including silicone-based siloxane, point out that silicone oil is a safe substance and can be used as a cosmetic raw material. In 2011, the 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, plants, and humans. Very low.
2. Impact on human safety
Human skin is not sensitive to various silicone oil materials, and the irritating effect of silicone oil is weak. Some cyclic silicone oils can be absorbed through the skin in trace amounts, but will not cause skin irritation or allergic reactions. Through clinical experiments, it was found that silicone oil has no significant impact on the human body’s urinary system, digestive system, and circulatory system. Longer-term clinical observational studies show that silicone oil does not increase the risk of cancer. The current impact of silicones on human immune stress has not yet been determined, but there is still no clear evidence that silicone oil will affect the immune system. So far, there is no experimental evidence that silicone oil materials have significant negative effects on the human body.
3. Impact on the environment
Linear silicone oil is difficult to be degraded by microorganisms in nature, but it can be hydrolyzed in moist sandy soil. The water-soluble oligomer can be further biodegraded into environmentally friendly substances such as carbon dioxide, water, and inorganic silicates, indicating that it cannot be permanently used in nature. exist.
