Film-forming technology is essential in sunscreen performance. Composite film technology, which combines "hard film" and "soft film" components, has revolutionized sunscreen formulations, improving water resistance, durability, and comfort. Trimethylsiloxy silicate (TSS), a high-performance "hard film" ingredient, plays a key role in ensuring long-lasting and effective sun protection.

TSS creates a strong, dry, and uniform protective layer on the skin, improving adhesion and friction resistance. Its spherical microstructure makes formulations easier to spread, enhancing user experience. However, relying only on "hard film" components may make the film layer too rigid, causing it to crack and compromise protection.

To prevent this, composite film technology incorporates "soft film" ingredients, such as dextrin palmitate, to improve flexibility and comfort while maintaining water resistance. This soft-hard combination ensures optimal UV protection while keeping sunscreens lightweight and breathable.

TSS has already been widely adopted in high-SPF sunscreens, allowing them to maintain SPF 50+ protection even after water exposure. This makes TSS-based sunscreens ideal for outdoor activities, sports, and extended sun exposure.

From a market perspective, composite film technology has enhanced the competitiveness of modern sunscreens. Consumers now seek long-lasting, waterproof, and comfortable sun protection, and TSS-based formulations are meeting these expectations.

Looking ahead, as sunscreen formulations continue to evolve, TSS is expected to play a crucial role in next-generation sun protection products, driving innovation in the beauty industry.
