MoisturizingBarrier

INCI: Polyquaternium-51

In short · TL;DR

Category

Moisturizing

Effect

Forms a highly water-retentive film with a biomembrane-like structure, giving a long-lasting moist feel

Concentration

Roughly 0.05–1% (varies by raw-material specification and product)

Effect

Forms a highly water-retentive film with a biomembrane-like structure, giving a long-lasting moist feel

Mechanism

A phospholipid-mimetic MPC polymer. Its cell-membrane-like hydrophilic structure holds large amounts of water and forms a water-retaining film on the stratum corneum surface for sustained hydration

Typical concentration

Roughly 0.05–1% (varies by raw-material specification and product)

Onset

Moisturizing feel immediately after application, with lasting moistness

Cautions

Generally low-irritation. Raw-material cost is high, so high loading is rare
