The study explores perfume encapsulation and release from micellar solutions, emphasizing the impact of perfume-surfactant interactions and micelle geometry. Examining two mixed-micelle systems with branched-tail (ST2S/CAPB) and linear-tail (SLE1S/CAPB) surfactants, the research systematically investigates the effects of time, perfume concentration, and dilution on micelle geometry and headspace release. Utilizing SANS, GC-MS, and statistical analyses, the study reveals stable systems over time, with increased perfume content causing micelle growth and dilution leading to micelle shrinkage. Both systems exhibit consistent trends in micelle geometry, except the branched-tail system forming a lamellar phase with added perfume. GC-MS headspace concentration correlates with micelle geometry, influenced by tail group structure. The findings contribute insights into the intricate dynamics of perfume-micelle interactions, crucial for formulations in material science and actives delivery.
