Under the scorching sun, sunscreen has become an essential tool for people to protect against ultraviolet rays, and the silicone film-forming agent in it can be regarded as the "invisible guardian" for sunscreen to exert its sun protection effect.
Organosilicon film-forming agents have a unique molecular structure, with their main chain composed of silicon-oxygen bonds and side chains carrying organic groups. This structure endows it with good film-forming properties, low surface tension and excellent flexibility. When applying sunscreen, the silicone film-forming agent can quickly spread on the skin surface, forming a uniform, continuous and transparent film. This film is like a fine protective net. On the one hand, it can closely adhere to the skin, fill the tiny grooves on the skin surface, and make the sunscreen agent in the sunscreen more evenly distributed, effectively avoiding blind spots in sun protection. On the other hand, it can prevent the loss of sunscreen due to factors such as sweat and friction, enhance the stability of sunscreen, and thereby extend the sun protection effect of sunscreen.
In addition, silicone film-forming agents also have excellent breathability. While providing protection, they do not impede the normal breathing and metabolism of the skin, reducing the burden and discomfort on the skin. Meanwhile, its low surface tension makes the sunscreen easier to apply and enhances the user experience of the product. It is precisely these characteristics of silicone film-forming agents that enable sunscreen to better exert its sun protection effect and provide long-lasting and effective protection for the skin.
