As film-forming agents, fillers and adsorbents, microplastics are often added to daily personal care products. Because of their chemical stability, they remain in the environment for thousands of years, endangering the safety of the environment and human health. Therefore, it is urgent to find an environmentally friendly substitute for microplastics. Using -octyltrimethoxysilane (OTMS) and tetraethoxysilane (TEOS) as silicon sources, a novel, environmentally friendly, organic hollow mesoporous silica system is designed with a high loading capacity and excellent adsorption characteristics in this work. In our methodology, sandalwood essential oil (SEO) was successfully loaded into the nanoparticle cavities, and was involved in the formation of Pickering emulsion as well, with a content of up to 40% (/). The developed system was a stable carrier for the dispersion of SEO in water. This system can not only overcome the shortcomings of poor water solubility and volatility of sandalwood essential oil, but also act as a microplastic substitute with broad prospects in the cosmetics and personal care industry, laying a foundation for the preparation and applications of high loading capacity microcapsules in aqueous media.
作为成膜剂、填充剂和吸附剂，微塑料经常被添加到日常个人护理产品中。由于其化学稳定性，它们在环境中存在数千年，危及环境和人类健康的安全。因此，迫切需要找到一种对环境友好的微塑料替代品。本工作以正辛基三甲氧基硅烷（OTMS）和四乙氧基硅烷（TEOS）为硅源，设计了一种新型的、环境友好的、具有高负载能力和优异吸附特性的有机中空介孔硅体系。在我们的方法中，檀香精油（SEO）成功地负载到纳米颗粒的空腔中，并参与了 Pickering 乳液的形成，含量高达 40%（/）。所开发的系统是 SEO 在水中分散的稳定载体。该体系不仅克服了檀香精油水溶性和挥发性差的缺点，而且可以作为微塑料的替代品，在化妆品和个人护理行业具有广阔的前景，为在水介质中制备和应用高负载量微胶囊奠定了基础。
