Unlike conventional synthetic microparticles, the readily biodegradable, non-nano powder provides a soft-focus blurring effect, reduces unwanted shine, and helps skincare products dry quickly without leaving a sticky sensation. The multifunctional ingredient can be incorporated into [serums, moisturizers, creams, and sunscreens](https://www.trendhunter.com/trends/light-serum-spf). Its UV-scattering properties may also improve SPF performance, potentially allowing manufacturers to reduce UV-filter concentrations. Esmeri SK1N10 meets the biodegradability requirements of EU Regulation 2023/2055, offering an alternative to materials such as PMMA and nylon-12. By combining desirable [skincare finishes](https://www.trendhunter.com/trends/is-a-sensory-enhancer) with regulatory compatibility, Eastman could help beauty manufacturers develop products that address changing consumer expectations. The ingredient may also support formulation flexibility as brands seek [biodegradable alternatives](https://www.trendhunter.com/trends/glucamate-evolve-thickener) without sacrificing product performance.
