Reactive polymer film network: LorealRecent Research Landscape

Lipstick transfer and smudging lead to poor consumer perception and frequent reapplication. These formulations utilize specific polymer-solvent networks to ensure rapid evaporation and durable adhesion.

What technical problems is Loreal addressing in Reactive polymer film network?

Petroleum derivative dependency

(19)evidences

Conventional cosmetic bases rely on petroleum-derived ingredients which face consumer rejection and inconsistent structural integrity. Replacing these with natural alternatives while maintaining specific rheological properties is the primary technical challenge.

Inadequate cosmetic film persistence

(14)evidences

The combination of volatile and non-volatile oils with resins indicates a failure of standard emulsions to remain intact on the skin. Improving film durability prevents premature wear and product migration.

Poor cosmetic film durability

(13)evidences

Natural resins and fatty substances often suffer from mechanical instability, tackiness, or poor adhesion on biological surfaces. Improving film integrity and wear resistance ensures long-lasting aesthetic performance.

Cosmetic pigment transfer instability

(12)evidences

Standard cosmetic applications suffer from rapid wear, transfer, and degradation over time. Improving film persistence ensures long-lasting aesthetic performance and resistance to external friction or moisture.

Structural instability in thin films

(11)evidences

Incompatibility between volatile hydrocarbons, silicone resins, and aqueous phases leads to phase separation. Preventing degradation of the emulsion structure ensures product shelf-life and uniform application.
