Polyphenol hydrogen bonding network: LorealRecent Research Landscape

Standard cosmetic coatings suffer from poor adhesion and mechanical wear on keratin surfaces, leading to frequent reapplication. This lever utilizes a two-component chemical reaction to engineer a durable, crosslinked network directly on the substrate.

What technical problems is Loreal addressing in Polyphenol hydrogen bonding network?

Keratin fiber surface degradation

(16)evidences

Insufficient adhesion and mechanical instability of cosmetic coatings on keratin surfaces. Enhancing film persistence prevents premature product transfer and degradation.

Poor coating adhesion to keratin

(5)evidences

Keratinous surfaces often resist durable bonding with external agents due to their chemical structure. Improving interfacial attachment ensures long-lasting cosmetic or protective layers.
