Further, the silicone compound is also widely used as a surface treatment agent for powder components.
• Silicone compounds have the above-mentioned advantages, but also have the problem that makeup is difficult to remove with water due to its high water repellency, and cleansing for cleaning puts a burden on the skin. Furthermore, since silicone compounds are usually not biodegradable, there is concern that they may accumulate in the environment for a long period of time, polluting the environment and disturbing the ecosystem.
