Benzalkonium Chloride

INCI · Benzalkonium Chloride

Benzalkonium Chloride is a quaternary ammonium ingredient used in formulation to help keep a product clean and stable over its shelf life. In rinse-off and leave-on textures it supports a fresh, well-preserved feel and contributes to overall surface cleanliness.

Mechanism in detail

What Benzalkonium Chloride does

Its cationic structure helps maintain formulation stability and a clean, fresh surface feel without altering the product texture.

Where it helps

Concerns Benzalkonium Chloride addresses

  • Dryness

    Dryness is a barrier dysfunction in which skin loses water faster than it can retain or replenish it, presenting as flaking, tightness, dullness, and roughness. Mild dryness reflects routine over-cleansing or environmental exposure; chronic dryness signals a deeper deficit in skin lipids (ceramides, cholesterol, fatty acids) and humectant content (the natural moisturising factor). Effective treatment hydrates and replenishes the barrier through three layered actions: humectants that draw water in, occlusives that seal it in, and barrier actives that rebuild the lipid mortar. The BIOSAR Hydraderm range delivers this layered hydration and visibly plumps dehydrated skin.
