The focus on liquid compositions and unit dose articles indicates the challenge of maintaining capsule integrity in chemically aggressive aqueous environments. Preventing early release ensures scent longevity and product shelf-life stability.

The use of polymer and salt hydrate matrices addresses the tendency of volatile fragrance compounds to dissipate or degrade before use. Controlling release through a stable matrix ensures scent longevity and intensity during the laundry cycle.

The keywords focus on the encapsulation and packaging of perfume particles to prevent the unintended release of scents before use. Solving this ensures long-term aromatic stability and controlled delivery during the laundry cycle.
