Polymeric microcapsule delivery systems: UnileverRecent Research Landscape

Fragrance loss during high-heat drying cycles reduces consumer perceived value, which is mitigated through controlled-release encapsulation. These micro-scale structures protect volatile actives from premature degradation in aqueous laundry environments.

What technical problems is Unilever addressing in Polymeric microcapsule delivery systems?

Fragrance loss during rinsing

(13)evidences

Volatile aromatic compounds dissipate or degrade before the consumer uses the treated textile. Preventing early release ensures long-lasting sensory performance and product efficacy.

Poor fragrance longevity on fabrics

(5)evidences

Volatile aromatic compounds dissipate rapidly during the wash cycle and subsequent drying. Retaining these compounds through controlled release prevents premature scent loss and improves consumer perception of cleanliness.

Inefficient active ingredient deposition

(4)evidences

Volatile active ingredients dissipate or degrade before reaching the target fabric surface. Preventing early release ensures long-lasting sensory performance and material efficiency.
