Most fragrance compounds—consumed for the pleasure of their fresh odor—are labile and volatile, making it difficult to retain the stability and sustained release of the fragrance. In a previous work, Hu Jing et al. established that the fragrance can be encapsulated into poly(butyl cyanoacrylate) nanocapsules via anionic polymerization. In a new study, they prepare a spherical polyacrylate nanocapsule with a higher loading ratio of fragrance via one-pot miniemulsion polymerization. When lilial (PNL) is applied to leather, some PNL remains on the leather surface after flexing 5000 times, demonstrating that PNL has an excellent fragrance sustained release property. The cover shows the micromorphology of the leather finished with PNL without flexing. DOI: 10.1002/app.40182
