Fragrance encapsulation is at an inflection point as regulatory pressure challenges the long-standing use of MF capsules, with no clear successor yet established. Biodegradable polymers, inorganic shells, biotech approaches and fragrance compaction are emerging as competing pathways, but questions around performance, scalability and compliance remain. A clearer view of where the science is gaining traction, where limitations persist, and how established and emerging players are responding can inform the technology choices shaping the next generation of fragrance delivery.
