Organic-Inorganic Multilayer Microcarriers with Superior Mechanical Properties for Potential Active Delivery in Fast-Moving Consumer Goods.

ABSTRACT: This study introduces an eco-friendly approach to fabricating superstrong, core-shell, composite microcapsules, offering a sustainable alternative to traditional insoluble microplastic-based materials like melamine-formaldehyde. These microcapsules were engineered with a thick CaCO₃ shell formed via crystal ripening in the presence of water-soluble poly(acrylic acid), encasing a hexylsalicylate oil core armored by hydrophilic SiO₂ nanoparticles. An additional polydopamine layer was deposited via oxidative autopolymerization at pH 8.5 for improved structural and surface properties of the resulting microcapsules. These microcapsules (D _3,2 = 8.8 ± 0.3 μm) were spherical, with a relatively smooth surface, and exhibited unique mechanical properties, whic
