Dimethyl silicone oil and its emulsion products have deeply integrated into various aspects of modern society due to their outstanding physical and chemical properties. However, public concern about their safety has never ceased. In fact, after decades of application verification, dimethyl silicone oil has been recognized as a material with extremely low toxicity and good biocompatibility. The US FDA and relevant institutions in the EU have approved its use in food, medicine, and cosmetics, as long as it is used in accordance with the specifications, it is harmless to human health.
The safety of silicone oil emulsions is also reliable. Modern emulsification processes mostly use non-ionic surfactants, which are gentle and non-irritating. In skincare products, it can effectively isolate external pollution and reduce the chance of allergens contacting the skin. However, for a small number of sensitive skin groups, long-term high-concentration use may cause clogged pores, so choosing an appropriate concentration of product is crucial.
Looking to the future, the development of silicone oil materials is moving towards functionalization and greenness. On the one hand, through grafting modification, researchers have developed new silicone oils with intelligent properties such as antibacterial, anti-ultraviolet, and temperature-sensitive response; on the other hand, in response to the problem of difficult degradation of traditional silicone oil, breakthroughs have been made in the research and development of bio-based silicone oil and water-soluble silicone oxides.
Under the background of the "dual carbon" target, the silicone oil industry is also actively transforming. The reduction of energy consumption in the production process, the recycling and utilization of wastewater, and the recycling and regeneration technologies of waste silicone oil are gradually building a circular economy chain. It can be predicted that in the future, dimethyl silicone oil and silicone oil emulsions will be more intelligent and environmentally friendly, and will continue to serve as key basic materials to support high-end manufacturing demands from medical health to aerospace, contributing to the sustainable development of humanity.
