Active ingredients often fail to adhere to fabric surfaces during the wash cycle and are rinsed away. Improving deposition efficiency ensures long-lasting sensory or functional benefits on the substrate.

Single encapsulate populations often fail to provide both immediate and long-lasting sensory experiences or fail to deliver across different usage stages. Using dual populations addresses the limitation of linear or insufficient scent longevity in consumer products.

The primary challenge in silica encapsulation is the premature leakage or inconsistent discharge of the encapsulated payload. Controlling release kinetics ensures the active ingredient reaches the target environment effectively.
