Polyol-stabilized pigment film networks: LorealRecent Research Landscape

Pigment agglomeration and phase separation in liquid cosmetics lead to inconsistent color application and reduced shelf life. Engineering the interface between coated pigments and polyol-based film formers ensures long-term suspension stability and uniform film deposition.

What technical problems is Loreal addressing in Polyol-stabilized pigment film networks?

Insufficient cosmetic film durability

(15)evidences

Standard aqueous and oil-based cosmetic layers suffer from poor adhesion and structural instability when layered. Improving film integrity prevents premature wear and product migration.

Cosmetic film phase separation

(3)evidences

Inadequate bonding between pigment layers and the skin surface leads to premature product failure. Improving adhesion ensures long-wear performance and resistance to environmental stressors.
